Cutting the piston rings with solvent. Engine cutter. Best round rings. And the most important thing

Information about the cleaning of the engine from Nagara (otherwise - cutter) will be useful to those motorists who constantly exploit one car for a long time and tries to serve it independently. This procedure is rather prophylactic in nature, although in some cases it allows you to reanimate force aggregate and extend the mileage to overhaul by 5-20 thousand km. How the engine cutter is performed with their own hands and what means for this are applied, read in this publication.

Where does Nagar come from and where does he accumulate?

The cleaning procedure is not a panacea and helps not always, and sometimes it gives the opposite effect. To use the methodology correctly and on time, you need to understand the reason for the formation of deposits and the consequences of this phenomenon.

Cylindropional (CPG) and valve group of internal combustion engine operates in heavy conditions - Ply high pressure and temperature. Over time, the fuel surfaces of the parts are wear out, and the glands lose the tightness of the combustion chamber, the engine oil begins to penetrate. The conditions for burning the fuel-air mixture deteriorate, since the lubricant flashes and forms a solid bloom on all available surfaces:

• piston skirts and chamber walls - first of all;
• the side surfaces of the pistons in contact with the walls of the cylinders;
• facial planes of valves and their inner surfaces adjacent to saddles;
• grooves for piston rings and removal holes liquid lubricant (are in the depths of the groove of the oilmaging ring).

At the same time, the spark plug electrodes are covered by nagar, which reduces the quality of sparking.

When the amount of lubricant penetrating the cylinder becomes critical, black coke clogs all possible slots and holes. Because of this, the rings are stuck in the grooves (on the jargon - they lie), which is why real compression in the cylinders falls by 50-90%. The valve burned from the saddle side will not close hermetically, and then the compression pressure will fall at all to zero - the cylinder will completely refuse. The consequences can be prevented if you make the engine cutting on time.

When to cut the motor?

The procedure gives a positive result with timely execution. It is impossible too tightening - only in vain will spend money, because chemicals are not suiced. When the cutter becomes useless:

1. With long-term ride with high oil consumption. If the motor "devours" 1 l lubricant per 1000 km of run and more, and you do not take any measures for 2-4 months, then get ready to make overhaul. Nagar will score the rings and holes of the oil removal, which chemistry does not help, only mechanical cleaning.
2. If compression in one or two cylinders fell to zero. This indicates the burnt valves that the cleaner will not take.
3. In case of noise and knocking in the motor, which requires immediate replacement of parts.

You can make the cutting on your own risk, but with the listed symptoms, the chances of success are extremely low. Sometimes there is an opposite effect - after cleaning the compression in the motor drops and further ride becomes impossible, the engine is much losing in power.

The reason for the phenomenon is the same Nagar. Covering all available surfaces, coke begins to serve as a seal instead of piston rings and together with lubricant creates increased pressure in the chamber sufficient to ignite fuel mixes (so-called oil compression). After cleaning, the sealing tag disappears, and the pressure in the cylinders falls due to the wear of the elements of the CPG. Motor refuses to work.

Practice shows that special fluid To cut the engine should be applied at expenses motor lubricant 0.3-0.5 liters per 1 thousand miles of run. At that moment, intensive deposition of Nagar begins, but irreversible consequences have not yet come. If the culprits of the oil "zhora" were valve oil seals, then after the procedure they can be changed and over 20 thousand km, provided that the CPG is in a satisfactory condition.

Choosing a cleaning agent

In automotive stores and markets, there are many diverse chemicals declared by manufacturers as effective purifiers of parts of power units from coke. Which of them are applied most often and deserved a positive reputation:

• Mitsubishi Shumma;
• GZOX;
• BJ-211;
• Lavr.

The first 2 drugs are fluid in aerosol packaging with a capacity of 220 and 300 ml, respectively, injected into the cylinders through the tube. The remaining two means are poured with a syringe. As a rule, one packaging is a canister or vial - enough for servicing one four-cylinder engine to a working volume to 1.6 liters. On the high power engines with the number of cylinders 6-12, 2-3 tanks will be needed.

A few words about the better to do the engine cleaning. The Unconditional Leader is considered tool Mitsubishi Shumma, tested in practice by many masters - motorists. The lack of one is too high the price of the drug (about 30 y. E. Per canister). Alternative - GZOX aerosol, showing similar results for half a smaller value. Fluids BJ-211 and LAVR closure a list of the best cleaners present in the automotive chemistry market.

Council. It is not necessary to use the old "grandfathers" engine of the modern car for cuttering, pouring a mixture of acetone with solvent (kerosene) and other ineffective fluids into the cylinders. They act too slowly and weakly dissolve the Nagar.

Preparation for the removal of Nagar

Before making a cylinder cutter piston group Engine, it is necessary to prepare thoroughly. First of all, to allocate time - 8-15 hours are given to the entire procedure. The exact exposure time is indicated on the packaging of the liquid - the cleaner. The operation is desirable to verify by the time of the oil replacement, since part of the dissolved coke stalks into the crankcase and the lubricant will have to be changed anyway.

To make a worn out motor itself, such materials and spare parts should be prepared:

• cleaning agent;
• engine oil and filter;
• new spark plugs;
• bolts - plugs suitable on the thread instead of lambda probes.

No need to create special conditions to create work, it is enough to have a flat platform near the house or garage. It is advisable to have a compressor from the equipment, but you can do without it.

The preparatory stage includes the following operations:

1. Heat the power unit to a temperature of 60-70 ° C needed to activate most cleaners.
2. Unscrew out exhaust tract oxygen sensors And put the stubs from the bolts. The goal is to protect the expensive electronic elements from clogging and soot.
3. Bring the car with anti-digit shoes and raise any leading wheel.

Instructions for rounding

Having warmed up the power unit before cleaning, it is worth pouring into the carcard washing composition - "five minutes" to remove the dirt from the oil channels. You should also measure the compression on the hot engine in advance, it will help to see the result before and after the cutting.

Further actions do in this order:

1. Carefully read the instructions on the packaging of the cleaning agent and find out how much fluid it is necessary to pour into each cylinder of your motor.
2. Remove the spark plugs and clean it with a brush on metal, rinse with gasoline and blow it.
3. Turning the drive wheel manually when the 5th transmission is enabled, set all the pistons into the middle position, measuring the depth of a long screwdriver.
4. The lowering tube is alternately into the candle holes, fill the cylinders with an aerosol from the canister. The engine "Lavr" engine is made using a syringe (comes with a drug).
5. Screw the candles back without tightening until you stop.
6. Hold 8-15 hours, periodically moving the crankshaft with a wheel with rotation. The goal is to help fluids penetrate between piston rings.

After the time specified in the instruction, turn out the candles again and try to pump off the cylinders dissolved with a syringe, and then thoroughly blow the compressor. The better it will be possible to clean the rest of the coke, the faster the engine will start.

Install old candles and run the motor without increasing speed above 1500 rpm. Give it to warm up and "spit out" pieces of Nagar through the graduation path. After 10-15 minutes of the engine, when the smoke from the exhaust decreases, return to the place of lambda probes and proceed to replace the engine lubrication.

New candles screw in the mostst reason when cleaning the power unit and change the oil. Before installing the candles, re-measure the compression and make sure the positive effect of the event. If the result is negative, start preparation for disassembly and overhaul Motor.

Outboard diesel engine Differs in the method of filling cylinders chemical means. Since the spark plugs are absent, the liquid is poured through the holes of the nozzles. The latter will have to dismantle, after throwing the fuel pressure in the system and turning off the pump.

Engine cutter - Removal of nagar with piston rings and piston grooves so that the rings have the "mobility" and the engine stopped "there" oil. It is also cleaning from the nagar valves and the walls of the engine combustion chamber to eliminate detonation and ignition skipping. The cutter can be made through oil, fuel and candle holes with various preparations. All these methods differ in the efficiency of cleaning from carpentry and laboriousness.
This article describes different methods Effective rolling in the engine, the pros and cons of these engine cutting options, as well as the causes and zones of the Nagar formation.

In our experience, in 95% of cases, the cuttless helps to avoid "Capitals", but sometimes it leads to the repair of the engine ("Zhor Oil" grows sharply). It may be associated with a large wear of the CPG details (there will be no longer anything here), or the coolant itself was carried out incorrectly (everything is in your hands here). Therefore, be careful when choosing a means and method of engine cutting !!!

All methods for cutting out the piston rings of the engine can be divided into 3 types: "Soft" cutoff, "tough" and in motion.

"Soft" engine cutting

The soft cutting of the piston rings is cleaning the piston group from a car through the oil system of the engine. Cleansing preparation (usually it is "washing the oil system with a rings cutoff effect") poured into the engine oil for 100-200 km prior to its replacement, and the engine must be operated in gentle mode, avoiding operation at maximum turns. The composition of the "soft" cooker must rebuild the nagar from the lower oil-free rings (which are most often susceptible to "bullshit" or coking) and piston grooves. Usually, washing butter is used for this, as well as 5- or 7 minutes.

The main minus of ordinary "soft" cutters: With their help, it is impossible to clear from Nagar neither the combustion chamber nor the engine valve. These are mainly the traditional flushing liquids of the oil system of the engine, with the addition of cleaning components to remove nagar. Such a method can be applied not in clinical cases of engine contamination, but as prevention, with each oil change.

Recently, the popularity of the engine cutter with Dimeksida is gaining. Mostly due to the cheapness of the drug (in the pharmacy it costs 50-70 rubles per bottle) and the quality of dissolution of the car in the oil system of the engine. Dimexide is poured into the oil neck at the rate of 100 ml per 1 liter of oil in the engine. The minuses have two ways to cut two: it is necessary to clean the pallet from the paint, so as not to score the oil-tank mesh (because the paint peels off and can score the oil pump mesh, break the oil supply to the pump) and rinse well with oil system (usually 2 times washing oil) After Dimskid's drain with old oil. Therefore, the costs grow to 1000 rubles, and the time will have to allocate a lot on such a cutting.

The "soft" cleaning of the engine from Nagara can be attributed to our additive to the oil of the active protection of Edial. Its addition to the engine oil allows Well clean the rings and piston grooves from Nagara and varnishes (not worse than Domexide),usually changes, from the use of additives, become noticeable after 10-15 minutes on idling And pass to 50 km. The main difference between it from other "soft" competitors: No need to change oil After use (replacement of the oil in the engine is planned). Our additive is filled both in "Fresh" and in the "old" oil and ride it until the end of the oil life. It is desirable that the car still drove on this oil at least 300 km so that the additive to work in full force. Its an additional plus serves the subsequent protection of friction pairs from wear and an increase in the resistance of oil on a volunteer.

"Tough" engine cutting

Rigid rings or old "Dedovsky Method" More common. The essence of this method is quite simple: an aggressive fluid is poured into the combustion chamber through the nozzle or candle holes that corrupt and softens the nagar on the rings and the bottom of the piston.

Method of application: the car is placed horizontally, the engine warms up to operating temperatureAfter that, turn off the ignition and unscrew the candles or remove the nozzles. Turning the crankshaft, with a wire or screwdriver exhibit pistons to the position close to the middle. Each cylinder is flooded with antikox (Lavr, Mitsubishi Noise, Greenol, Dimekside, Hado or Hairdryer) and is left there for a certain time - from 20 minutes to 12 hours for softening of the Nagar (depending on the manufacturer of such drugs). It is necessary to warm up the engine to enhance the procedure, the effect of "steam bath" is created, the nagar is better than "swelling" and softened.

Candle wells are closed at the same time, slightly putting the candles so that the engine does not quickly cool, and the ignition is better to turn off just in case. After that, the candles are twisted, and by scrolling the crankshaft starter from the combustion chamber all cleansing fluid is removed, often applying a syringe with a tube. This is the one that did not learn through the piston rings in the Carter. Candle holes are covered with a rapid, so that the dirt is not very scattered out of the holes and did not sleep all the inconsistent space. Then spin the candles, the engine is crushed and give it to work on variable turns or drive around 50 km. Next, the most important thing: required Before change oil and candles.

This technique today is quite actively used both at a hundred and car owners independently.

Cons "tough" cutter

The effectiveness of this method depends on the quality of the antiqua used (acetone or a mixture of kerosene with acetone was usually used in the Soviet time in the same proportions), as well as from the type of engine serviced. It is often possible to remove only the nagar on which the jig of the cleaning solvent came (i.e., the top of the piston and rings), and the walls of the combustion chamber and the valve are almost not cleaned. Recently, Mitsubishi Noise is gaining popularity, because It does not fall down when injected into the combustion chamber, and foaming fills its entire volume and cleans the entire combustion chamber, including the upper part of it and the valve.

Such chemistry is pretty toxic and applying it in the garage can be poisoned with poisonous pairs. IN winter timeThe quality of the dissolution of the Nagar strongly affects the rapid cooling of the engine, and in the frost, unscrew the candles or shoot the nozzles, the occupation is not pleasant.

It is not clear how much it is necessary to fill in the amount of solvent into each cylinder for the greatest achievement of the result, because Engines are different, different volumes of the combustion chamber and piston diameters, and the instructions for use for all engines are the same (in 2.5 liters of engine and in the engine of 1.3 l. The same number of pistons). Nallate a lot, there is a chance that a large amount of drug will be leaking into the oil and destroy rubber seals, it is not enough to clean, you can really clean anything.

Particularly destructive action from the rivet Greenol. An hour after the fill to the combustion chamber, she seeps through the rings in the crankcase and begins to squeeze the paint from the pallet. Therefore, this rounding is best used to clean the parts from the car already disassembled engine, lowering the part in the bath with Greenol, there is no competition. By the way, the developers of this cutoff show the rollers precisely with cleaning pistons with the removal from the engine.

Often, after the fill to the combustion chamber, the cutter is quickly seeping into the engine crankcase (through the castles of the rings) and does not perform its functions for cleaning the piston grooves and drainage holes, not to mention the walls of the combustion chamber.

It is quite difficult to independently set the pistons in the middle position, for this operation you will need at least one helper. If a car with automatic transmission (it is not pushing it backwards), then a lift or jack will be required for the cutting, to raise the drive wheels.

Opposite engine cutting

The engine design also strongly affects cleaning from Nagara. Suppose it is necessary to cut the SUBARU car with the opposite engine: raising the hood, it is not clear where the spark plugs are found there, and you still have to get to them, unscrew and try to pour antiques to the combustion chamber. Opposite engines are located horizontally and the cleaner follows from the combustion chamber until you turn the candles into place. Put pistons in the middle position on opposite Engine It is completely problematic, plus the rounding will clean only the lower half of the combustion chamber, and, accordingly, the lower segment of the rings. Although the effect of "steam bath" is created, but it is still better when the Nagar is completely covered with a reagent than the decomposition of it under the ferry.

Drawing V-engine

The same can be said about multi-cylinder V-shaped engines, where access to candles or nozzles makes the attachments and attachments. Plus, the pistons are under the tilt, the rounding will be unevenly affected by the Nagar, it means there will be more preparation for dissolving Nagara. Cleaning the rings in such a method of diesel engines in general is problematic. First you need to get to the nozzles (the same attached units), then remove them, and this often requires special pullers or no-intensive keys. After removing the nozzles, copper sealing washers should be changed (they are no longer suitable for reuse), which must be bought, and this is a trip to a specialized store, where they are not always in stock.

Another problem: the education of jelly loans. With the "hard" engine cleaning from a car, the oil was washed from the cylinder wall with a cleaning reagent and the first start of the engine is carried out "on dry" i.e. Rings are drunk along the sleeve without oil, which leads to additional jams on the sleeve and the sharp wear of the piston rings.

Be sure to replace the oil in the engine, because Part of the drug through rings penetrates the crankcase and is mixed with oil, which changes its properties and will adversely affect rubber seals and glands. Usually subject to replacement and spark plugs.

Cutting rings in motion through fuel

Engine cutter through fuel - burning in motion. itthe easiest to carry out, but no less effective way to combat Nagar. The essence of the method is the use of special additives into fuel to combat Nagar in the combustion chamber. Here for now Corolor Edialhas no analogues in the auto chemical market. Clean the engine using our additive is the easiest, not time-consuming and budget way. It does not require special skills, tool and a bunch of time to remove and install the candle or nozzles. By the time of administration of the drug, you spend no more than a minute.

The edinal is filled into the car's tank and, together with fuel, enters the combustion chamber. On the operating engine of the additive particles (falling with fuel to the combustion chamber) penetrate into the thickness of the car and lacquer sediments and completely burn them, and the residues are removed through exhaust system. The essential difference between our engine cleaning method from others, also in the fact that the burning of the nagar occurs faster with high load and speeds. Those. The operation of the car is carried out without restrictions on the load, in the usual ride manner, and riding on the track significantly helps cleaning from Nagara.

Outcasting of oilmaging rings

The most problematic zone in the piston rings is the oil surcharge rings. The only effective way to clear them is an increase in the exposure time on the Nagar. Here it is more efficient to simultaneously apply 2 additives: Active defense in engine oil and Edial rounding in car fuel. Our drugs will gently clean the piston grooves from Nagara, freeing the rings. If the rings do not "revive" immediately, throughout the run, up to 300 km of "Zhor" oil will fall sharply or completely stops.

If the consumption of oil on the paste was about 1 liter per 1000 km of mileage, then 100% of the result may not work, because (According to statistics), oil surgery rings can be simply erased. Also, the turbocharged Vagovsky engines are heavier than the cutter (the drainage holes for draining oil from the piston groove in Carter are poorly cleared. Especially the turbo folstswagenes (1.8l) suffer from this. It can be advised several times to apply the complex or after our complex to the oil and fuel to apply " Tough "cutting (noise) and replace the oil in the engine. This should help.

Cutting valve

If the car is operated mainly in urban conditions (low turns and frequent work at idle), then the valve is quite quickly fascinated by Nagar. Our roundabout Edial fuel is well cleaning the tart on the inlet valves, providing tightness in the "valve-saddle" pair. What eliminates ignition pass and improves the dynamics and efficiency of the engine.

Best round rings

If you decide to make the cutoff yourself and there is no desire to unscrew the candles or shoot the nozzles, then our recommendations. With "Zhore" oil engine more than 0.5 liters per 1000 km very efficiently in the complex (at the same time) apply Edial rounding (bay her into the car tank) and EDIAL engine active protection (bay it into engine oil). It is best possible to remove the tart from the rings of the engine and clean the combustion chamber and valve. On the V-shaped engine, it is effective to fill 2 bottles of active protection into an engineering engine.

Poured into the oil for 15-20 minutes of operation of the engine clean and "revitalizing" the rings of the engine, and the cooler flooded into the tank auto will carefully burn out the entire nagar in the combustion chamber. Especially this complex approach is recommended to motorists who are moving only around the city.

At the same time, our engine cleaning method Edial has in front of other competitors presented in the market, a number of significant advantages:

The speed of making the drug (flooded into the tank of the car and engine oil - and ready !!!).

After cleaning the engine from Nagara, it is not necessary to change the engine oil, since the decomposition and combustion products of nagar and lacquer deposits are removed through the car's exhaust system, respectively, do not seep into the crankcase and do not affect the glands. Our car chemistry can be applied to any time convenient for car owner.

Piston rings of the engine are well cleared.

It is perfectly cleaned by the nagar from the parts of the combustion chamber, including intake and exhaust valves, their landing saddles and spark plugs, increasing their service life.

Due to the effective recovery of compression, it reduces the fuel consumption and oil consumption, increases the power and pickup engine.

On the surfaces of the parts of the combustion chamber and steam of friction in the engine, protective films are created preventing the appearance of Nagara. These films reduce the subsequent coking of the rings due to the decrease in contact temperatures in the combustion chamber and, consequently, a decrease in the destruction of oil molecules.

• Edial additives (integrated use in oil and fuel) combine the ability to neatly influence the rocked piston rings as a "soft" method of cutting and the complete cleansing of the parts of the combustion chamber from Nagar, which is not always achievable with the "hard" engine cutting method.

AND THE MOST IMPORTANT THING:

Any cuttlefish is good as prevention !!!
It is like oral hygiene in humans. Teeth you brush constantly, remove the "dental flare". So the cutoff should be applied on the engine periodically as prevention. As soon as the "Mased" appeared - do the cutter so as not to erased the rings (especially oiling). Do not bring the engine coking to a critical state when "reanimate" the engine can only replace the rings. For this, our additives are developed that are very simple and effective in use.

Causes of Nagar Education In Engine

The operation of the engine on poor-quality fuels or oil leads to the enhanced formation of a car in the combustion chamber. The bottom and walls of the piston, as well as the walls of the combustion chamber, turn by naigar and carbon sediments from not burnt fuel. Valves overwhelm in Nagar, and in some cases just roasted. Piston rings are kinking and lose mobility, the walls of the combustion chamber are in force by Nagar, worsening the heat sink. Also, the formation of Nagar contributes to the presence of additives in fuel, decomposition and oxidation of oil in the combustion chamber. Frequent ride on not heated engine with a small load, riding on small speeds, standing in "traffic jams", winter riding - All this contributes to the intensive formation of a car on the surfaces of the combustion chamber.

A large amount of nagar (decrease in the volume of the combustion chamber) leads to detonation. Detonation reduces engine power, increases friction losses and wear engine parts. In addition, the passage sections of intake and exhaust valves decrease (deterioration of mixture formation and the increase in fuel consumption). Nagar, who fell under the valve, leads to his loose landing in the saddle, causing the valve over time. The loose closure of the valves also leads to a significant drop in compression, respectively - the power loss of the engine.

Recently, very carefully acquire the engine oil. Often, modern motors of Euro5 and 4 pour oils designed for euro-class engines to toxicity. The inconsistency of the oils used leads to the burnout of the oil in the combustion chamber and the rings crooking, because motor oils For EURO5 engines, the temperature is maintained to + 110-115 degrees, and motor oils of the Euro3 class only 90 degrees. Therefore, if you fill such an oil in modern engine It will burn out.

Nagara education zones

A thick layer of nagar on the valves significantly worsens the engine operation. Especially dangerous deposits on the reverse side of the inlet valve plates: they act as a sponge and absorb fuel. The engine is forced to work on a depleted mixture. The result is a possible detonation combustion of the fuel mixture and damage to the engine.

In the grooves of the piston rings, on the side surface of the piston and the walls of the cylinders, medium-temperature sediments are formed - varnishes. Nagar and varnish on the top edge of the piston accelerate the cylinder wear. Varnish in the piston grooves and the carved tart rushing the piston rings rushes there, reducing compression; Begins to increase the consumption of oil "On the Ear". When the deposits completely fill the gap between the piston groove and the ring, the ring is cutting, squeezing it out. The pressure on the walls of the cylinder increases sharply, the wear of the sleeve and rings accelerates, even may occur on the walls of the sleeve. Through the "cluttered" rings increases the breakthrough of gases into the crankcase, and oils into the combustion chamber. It even more increases the formation of varnishes and nagar.

All this leads to a drop in compression in cylinders, reduced engine power, poor launch, overcurrent fuel and oil, increase the toxicity of exhaust gases. With a strong nagar, the "autorun" of the engine is possible after the stop. Because The volume of the combustion chamber is noticeably reduced and carbon particles continuing to smoke fuel and the engine continues to operate.

Causes of oil entering the combustion chamber

In the combustion chamber, the oil falls in two ways:
1. From the walls of the sleeve, because the oil-changing rings cannot remove it perfectly clean.
2. From the rods of the intake valves, the oil is washed off into the cylinders with a flow of fuel mixture.
These are only the main ways of getting oils into cylinders on "healthy" and new engines. And when the car's mileage passes for 100,000 km and you will notice that the oil taking to the desired level has become frequent, and haze with a specific smell began to appear from the muffler, it means that other elements were connected to the addition of oil in the combustion chamber.

An experienced motorist for the exhaust and the condition of the candles will definitely determine because of which such smoke and oil consumption. The main perpetrators are two:
I. — oil reflective caps valves. Here only their replacement will help, there are no other options. ( Signs of "leaks" Oil reflective caps:
1. Smoke from the exhaust pipe when fugazovka.
2. The presence of oil on the threaded part of the candles ("wet" thread on candlelight).

II - cylindropional group(rings, pistons, cylinders). There are already possible solutions to the problem. And if you are offered to sort out the engine and replace the rings, you should not hurry. In most cases, the engine cutting and a resource to "Capitals" increases by 50-100 thousand km, and even more.

R Rymerno 50 years ago in front of the designers there was a task to create an engine that could be transferred sometimes very hard modes of the piston group and the disgusting oil work. And she would have supported long work on the verge of detonation (and even behind it), repaid mixtures and long-term operation with maximum load and small turnover. Approximately under the same conditions there are also modern motors.

Let me remind you just in case that detonation is not cotton short-lived fuel in the muffler, but the process of explosive combustion of the working mixture in the cylinders. In this case, the explosive wave destroys the parts of the engine, and the combustion temperature rises. Easy detonation with early ignition gradually destroys the pistons, forming the craters on the surface, spoils the spark plugs and valves. But the detonation of the mixture is particularly detonated until the ignition is - in this case, the pressure in the cylinder increases particularly sharply, and the explosive wave can break the piston finger, bubming the connecting rod or deform the liners. And if detonation appears several consecutive clocks, then the sharp increase in the temperature of the exhaust gases (EGT. ) Includes to melting pistons, especially if there are local overheating places due to gas leaks in Carter.

Precisely because of the risk of detonation petrol engines It is necessary to be content with a small degree of compression, a mixture is close to stoichiometric and adjust the working process in throttling.

Progress is cyclic, and at the new stage of the DVS development, once again I had to bring the workflow to the very "edge". In the 1960s, the designers had a problem with accurate mixing formation (it was before the mass introduction of injectors), and the chemical industry could not even give high-quality oil, retaining its properties in different conditions. Now the causes of detonation are others - just an increase in temperature and work on the verge of possible allows you to save fuel. But the essence is nevertheless alone. A piston group of modern motors - in the risk area, crankshaft inserts and all bearings also get, oil cocks in the block and especially on pistons. Hence the need for "Kapitalka Light" by 120-150 thousand kilometers of run.

Why it is necessary

The mobility of the piston rings, the tight fit of the valves and the purity of the combustion chamber are three factors that strongly affect the efficiency of the engine. Piston rings are responsible for compression, heat removal from the piston and the amount of oil remaining on the walls. When the transfer of heat from the piston is disturbed by reducing their mobility or complete cylinder, the temperature of the piston rings themselves sharply increases and the oil is increasing. The thickness of the layer on the walls of the block becomes too large, and the temperature of the upper layer of oil film begins to grow. All these factors most negatively affect the likelihood of detonation and contribute to the destruction of the piston and piston rings, up to the rogs and the appearance of cracks.

The tight fit of the valves is important both to provide compression, on which the combustion efficiency depends on the cooling of the valves itself - heat from the valve plate for the most part goes into the head of the block through its chamfer. And if the contact is bad, then the valve overheats, and now the detonation is raised again.

Well, finally, the cleanliness of the combustion chamber and piston depends on the degree of compression of the motor (after all, there may be a lot of blood) and the degree of absorption of the piston and the GBC heat when combustion of fuel. And the various solid particles of nagar and irregularities of the walls contribute to the appearance of foci, the same crushing detonation, which is trying to avoid all the might.

Once again, summarizing: on all modern motors, the working conditions are so severe that the oil is cocking on the piston rings, the walls of the cylinders and the valves are very active. To 120-150 thousand kilometers, you need to do something with it, and if you neglect, you can destroy the motor detonation for the next 20-30 thousand. Question - Is it possible to save on repair, limiting the chemical cutter?

Drawing process. Dedov methods

For many years the work of the DVS We learned to restore the purity of the piston group and the combustion chamber in several ways. The most "grandfather" undoubtedly can be considered an attempt to clean everything with a mixture of kerosene and gasoline. Gasoline in the mixture is not for better combustion, and the kerosene is less in harming the rubber parts of the engine.

It is enough to pour the mixture into the cylinders and occasionally "move" the motor, turning the crankshaft there and here to facilitate the passage of the mixture to the piston rings. Hold how much you can, then scroll the motor starter, and the remains of the cutting mixture together with dissolved mud will fly out. A little mixture will fall into the crankcase and evaporate later.

The method is quite popular and now, the benefit components are available to any, and only a candle wrench is needed from the tools. Yes, that's just the effectiveness of it is extremely low, because it was designed for laundering a relatively low-temperature ash, and the process needed to repeat literally every couple of months. Modern motors Nagar is completely different: hard, high-temperature, even if it turns out due to the combustion chamber of the oil.

A much more exotic way turned out to be an arrangement of water, it is an alcohol cutoff. Once people noticed that on the motors that injected the water metal mixture on the leaf, the piston and the combustion chamber is simply shiny. The search for reasons indicated water - it is she who is responsible for cleaning the combustion chamber. The shock dose of the steam acts perfectly on all sediments, because water is a universal solvent. And the combination of H 2O + O 2 is generally a slaughter high temperatures. Of course, steam does not penetrate too deeply, but there, where it penetrates, bows from the metal literally layers of layers. And they already fly out with exhaust gases further.

On the carburetor motor, the cutter process was usually in mixing gasoline and vodka in proportion 1 to 1 and feeding the mixture to the inlet of the carburetor. Then everything is simple: the "SUPPLC" turned on, and the motor sucking the mixture. Hour of work at idle or unhurried movement - and the unit is clean. You can ride further, but often the operation was performed before the overhaul so as not to wash the details manually.

The same methods, but today

In fact, little has changed since then, but a more resistant Nagar in a much smaller volume does not even harm engines. Yes, and the focused piston rings are easier, less, but the "stick" in the groove is already completely tight. Dedovsky methods have to be improved.

Unfortunately, over the years of the development of motors, they have become not only more powerful and more compact, but also covered with a number of very fragile and sensitive to all processes in the combustion chamber of components, lambda sensors, EGT sensors, direct injection injectors and, finally, catalysts and summary filters. All of them are not at all welcome flying from the combustion chamber solid soot and water drops. And even more so do not rejoice in incomprehensible hydrocarbons in the liquid phase with impurities. But the need for a motor cleaning remains. What to do?

The improvement of the conventional cutoffs of kerosene led to the appearance of a whole arcsenal of mixtures. Sometimes little different from the "original" garage bottling, and sometimes very innovative and carefully worked out.

Most of the mixtures are one or another set of solvents. The most useless is mainly of kerosene with minimum impurities, more advanced contains xylenes and solvents that dissolve far faster and better.

But in addition to very conservative solutions, there are also real masterpieces like Mitsubishi Shumma composition, which also contains a solution of ammonia (ammonia alcohol), and a complex of organic acids. Of course, in the title of this composition, it is not in vain. automotive company: this is service fluid And perhaps the only one of its kind. Once, when the GDI motor series appears with a direct injection, it was found that due to the rigid workflow and the type of injection, they have an increased solids in the gases and the tendency to the nagara formation. The company has developed a special mixture for prophylactic work, because not to disassemble the motor for cleaning every 15-20 thousand kilometers? The effect of application is noticeably more pronounced than from ordinary organic solvents, this composition and a few of the likes are really capable of changing something in the operation of the motor and even avoid already the brewing repair.

Drawing water was also useful. On motors with gasoline injection, it is a bit more complicated than on antique carburetor, but the essence of the same. Water in this case is fed through a dropper or a different dosing device at elevated circulation. The effect is exactly the same. There is an option when the composition is supplied by a special machine through the fuel ramp of the engine, and in the process combined with water and solvents.

Well, with turbosways, it is still clearer. They work in all modes and turnover at the limit of workflow forcing, which means even a slight improvement in the characteristics of the combustion chamber and the piston greatly facilitate their lives. Yes, and the piston rings they work at high temperatures, so once again clean at least the zone of the upper piston ring is already beneficial.

Do you behave personally and what exactly?

If your car over five years old and / or has a motor from a risk group, then most likely there will be no chemical cutoff. It will allow you to slightly improve the performance characteristics. But in the launched cases, when I want to eliminate the oil appetite, everything is not so unequivocal.

On the motors of the old design and with a large wear of the piston group, the effect, oddly enough, is well pronounced, because the gaps are increased, and the fluid easily penetrates down. On the relatively fresh designs of the effect engines may not be at all, since the reasons simply cannot be eliminated in this way.

In general, as a temporary measure of the cutter can help in some cases. But if you are aimed at the long operation of the car, and not for sale it in the coming months, then from the "Kapitalki Light" with the replacement of the rings you will not leave anywhere.

Did you do the cutter?

Alexey and visitors good day All! This is again Dmitry and repeat about his experiments with solvent. The story of the freshest, did on this weekend (09/23/2017-24.09.2017). Since I do not lead my blog, we will help it!)) I write, trying to keep the neutral position, without taking the side of any fans nor opponents of solvent in the car. And people themselves will conclude - it is necessary for them or not. As I have already written earlier - I made a solvent as a roundabout of Alexey recipe (with some of my additions), and poured a small amount of solvent in the benzobak. Both episodes are described above. Go ahead. I remind you, I have a Mazda CX-7 gasoline 2, 3 turbo 2011 G.V., chip-tuning 270 hp, the car is not killed, there is no sharp need for something emerge there no Necessary, I like to ride on well-groomed machines, but not to be experimenting in reasonable limits. So, pour 1, 5 liters of solvent in 40 liters of fuel seemed to me little. I went further.))) The spouse, having learned, in the hearts said: "When you achieve it and calm down")) Lovy said. She trusts my experiments ... In general, this time, I am in an almost empty tank (gasoline remained 70 km - with my consumption it is liters of 8 approximately) flooded 8 liters of solvent! And of course to reduce the risk of detonation (remembering that octane number The solvent is about 70 units and burns in the chambers not completely), did not go on the car, but left to work at idle. The meaning of this operation was exactly the fact that the solvent does not fully burn and having the properties of the solvent of varnishes and resins, it will clear not only the fuel route, but also exhaust, reaching it after the combustion chambers. The engine left to work until completely exhausted, or rather - until everything ended ... In the tank ... the car worked at idle 7, 5 (seven and a half) hours. As a result, I'm exhausted. In general, in a half-night night, I could not stand and drowned the engine, fuel remained in the tank (I suspect that one solvent remained) 30 km. Now that all this time happened with the car. On the entire period of the engine, the engine was white smoke with a characteristic odor. Not so white (already transparent), as with the first rounds, but quite thick. It was hoping that there would be a lot of soot from the neutralizer, but, or whether the neutralizer is clean, or it does not work with the soot)) Saya went out (rubbed the pipes until pure and they smoked again), but I repeat, not so much. But what a lot happened so this water !!! From one pipe is slightly smaller, from another, but in general, gram 200 (two hundred). It was late to substitute a measuring cup. In principle, on the remaining solvent, both in the fuel route and remains in the tank, the car had the right not to be placed. I poured the prepared 10 liters from the gasoline canister and turned the starter. I started as usual, the starter spinned no longer than the usual, the car was not troil, turns as usual, 650-700 per minute. In general, everything is as always, the only thing that resembled the experiment is the smell. On this canister drove to refueling kilometers 80 and flooded full tank. The car was driving a little worse than the usual - not Troil, but also did not work. Consumption per half liter is larger. Another half-tank drove on gasoline, and the car ran down everything. Not a valley, so let's say. Yes, even on the engine, remembered. He began to work a little louder, as it seemed to me. The noisometer was measured - "it turned out to be", 84 decibels on average per minute at the intercooler as before the experiment, well, 83 was that a small difference. But there was no precipitate anyway, I don't really believe all these iPhonov applications. On my hearing \u003d still dialing intensified. And yesterday, after a common run after filling and solving solvent, 350 kilometers (my usual running route + three days in the city) The machine began to go at least no worse. Walit as it should be. Yes, more: all these 350 kilometers smoke from exhaust pipes continued to be white. The engine has not been quieter. But! First, smoke again transparent, almost nothing smells, there is no water from the pipe (a little bit of night condensate, which is normal), and secondly, it also takes as it should. At high speed as it would be better to take better. I think it cleared the turbine into which exhausts from the collector go.

Regarding solvent at one time (10-15 years ago) wrote a journal "driving" in particular that in all flushes of the fuel system, solve solvent, although packed in beautiful jars

Viktor Markevich

I own Shevi, I wash the engine with coal solvent before the replacement fill in the Motor 1/3 of the Solvet Bottle Work at idle 15-20min. I drag the work. As a flushing, since thick and can be gasped on it to gas and pour 1/2 beds of solvent into it and idling 20 more-30. Min works Motor after that drain through the work. And pour fresh oil. I do not use the washing oil because I do not see the point in it. The solvent remains will evaporate through the ventilation of crankcase gases under the lid of the valves, everything glitters oil by changing every 5 thousand km anywhere else does not flow through the norms. Many machines were washed with such a method including dieselk paint. Do not raise the secret. Before you throw something about the dosage, you don't need to dilute the oil to the state of the water and gas like a fucked and then fooling the solvent killed me. No need to pour into the side engine bucket of solvent and wait for the miracle to wash it is necessary in a gentle mode and in no case to pour solvent into flushing oil

Zloi Morder.

solvent on the glands do not act in any way abandoned the gland in the neck with solvent no changes in the alive

Evgeny Syroyzhkin

everything made the solvent rinsed and dismissed the engine 2l hand the result is tangible rinse do not be afraid)

Dmitriy Kiselev

Interesting. I have a diesel engine. It will be necessary to change the solvent before changing the oil. Like.

Hello Alexey!
Last night in the garage, made on your technique this washing with solvents. Automobile Alfa Romeo 159 (2, 2 gasoline), mileage 173 thousand km. There is a problem of zhore oil on the OK.0 track, 5l per 1 thousand km (oil city does not eat), plus a lot of soot in the silencer, but there is no smoke at all. I didn't have any smoke, I thought something would not be taxed, but everything went smoothly)) Conclusion for today at the end of all procedures with the oil change, but at the same time and the car began to work a little His quieter, on the proven oil barely noticeably, so clean)) in the middle looking through the oil-fuzzy neck, the islands of pure, washed metal, but mostly a lot of dark yellow plaque. I will continue to continue the procedure before the following changes in the oil. It will be interesting to know, I hope it helped, but it will only be noticeable on the track. In general, I would like to thank you that on the bare enthusiasm make such a necessary work and enlighten people. For you and health!

Arthur Max

So the neighbors on the garage of the fucking when I began to rinse, cut down and all the solvent, rusted the reptiles, say the piston to fly out the current to catch

Andrei Henri

Hello, what do you think you can ride with solvent in oil or only idle?
Let me get to the pit from the garage for about 10 minutes.

After solvent, I will try to rinse it still. Can help?

All that was shown was confirmed with washing, and engine shower. Compression rose by 2, 5 atm.

Andrei Tsarik

Alexey, what is your red valve? I tried to do this - a crane on air filter And the hose in the backwater hole, the Sapun down. But stalls. Echo no.

Of course not. All the favorite and respected Opel Vectra in the FRO KVS trilionnik.

Alexey and visitors, good day to everyone! This is again Dmitry and repeat about his experiments with solvent.

Thank you all for patience ... For many letters)) P.S. Like is a thumb up))) "A new answer is left

Alexey and all visitors great hello!

Friends, reporting: two tanks (about 1000 km) in a mixed cycle for 1.5 liters of isopropyl alcohol (99.7% purity) added to 60 liters of 95 gasoline, after it cleaned the solvent of the fuel route 8 liters of solvent on 8 Gasoline liters in the tank.

The car on alcohol was eagerly swept. Now a full tank of 95 gasoline without alcohol and solvent. No complaints about the work of the aggregates.

Personally, my conclusion on the reaction of the machine to the previous procedures described above is very effective, it is what is a straight fill in candleys (and further in combustion chambers) solvent without any impurities. As for the maximum risky flushing of the fuel system purely on solvent (8 liters) - as it was described above, it came to the conclusion that with the same effect you can reduce the risks of detonation and others, which way: not pouring a small amount of solvent in the benzobac ( 1.5 liters per 60 liters of gasoline - it is inffective) and not pouring a large amount of solvent (8 liters of solvent on 8 liters of gasoline - it is still risky), but to do so (I repeat - the effect will not be worse, and the risks for your car are less ): In almost an empty tank, there are 8 liters of solvent + 1.5 liters of isopropyl alcohol (you can buy in a radio shop, in Moscow 500 rubles per liter in Chip and Dip) and tighten 95 gasoline to full tank (if such gasoline on the manual, if 92 - So Pour 92). And you can go as usual. If the alcohol to the solvent does not fool, then I personally recommend on the car, do not ride, but to develop solvent at idle and only because the solvent is an octane number 70 and there are risks when opening a choke is more than 50% with a load, to get detonation. Alcohol 99.7% with its approximately 150 octans is balanced by solvent and will strengthen the cutting, which will reduce the number of "garbage", which goes into the exhaust manifold and reduce the "glukeness" of the catalytic neutralizer. At the same time, the increase in temperature on the lambda is not feared. In general, we arrive at the banal formula: the cleaner the fuel, the cleaner the exhaust, the better all the intake-release nodes work, the cheaper the car service))) Thanks Alexey for solvent !!! And thanks to all for your feedback!
