Soft flushing engine cooling system. Wash engine. Should I wash the engine? Engine soft wash

the main / About cars

The engine is one of the main components of all types of vehicles, without which the operation of the machine is impossible. Over time, its details are gradually wear out, and also fail. To preserve their performance and extend the operational period of the elements, it is necessary to provide high-quality care. For this, experts recommend using special means Soft flushing engine cooling system.

What is the flushing of the engine cooling system?

Soft flushing of the engine cooling system is a substance that is used to carry out a thorough flushing of radiators of heating and cooling the cabin vehicle, as well as the remaining components of the cooling system. With its help, they are fairly easily cleaned of dirt and dust particles that accumulate when active work this mechanism.

To date, soft flushing is used quite wide. This is determined by the fact that the tool is effectively and very quickly dissolves the scale and other contamination, turning them into colloidal particles. Thus, the substance contributes to preventing radiator clogging by cleaning products. In addition, it does not destructive effects on sealants and gaskets, and also does not interact with various cooling fluids, so they do not need to replace them.

Soft flushing of the cooling system with regular and proper use gives the following effect:

Intensively increases the productivity of the heating radiator of the car;
Helps to increase the heat sink of the engine, preventing it overheating;
Prevents the development of the effect of a calil ignition;
Significantly slows down the corrosion destruction of metal parts;
Prevents the appearance of microcracks;
Supports the cooling system in almost perfect cleanliness.

In which cases it is necessary to make a soft flushing of the cooling system?

With the active operation of the vehicle, its cooling system is constantly subjected to corrosive destruction as a result of the fact that on the walls of this mechanism, the decomposition products of the antifreezes used, as well as products of corrosion, scale and other extraneous particles, are gradually postponed on the walls of this mechanism. In the consequence of this, there is a significant reduction in the heat sink from the combustion chamber and the occurrence of the effect of the vibil ignition, which leads to detonation, reduce the power of the engine and the significant overvoltage of the engine. Due to the deterioration of heat transfer, there is a sharp disruption of the temperature mode of the device, causing overheating and even the engine breakdown.

This composition can be used at all stages of antifreeze. In addition, on vehicles with a sufficiently polluted cooling system, a soft flushing must be used in about 2000 km prior to replacement of coolant.

In most cases, with the help of such a means, the device is treated every 50-60 thousand km. Driving a car before pouring a new antifreeze.

What is the soft flushing different from others?

Soft flushing is a unique solution developed by the latest technologies. It effectively restores the efficiency of the engine cooling system directly during the use of the vehicle. This increases its operational period.

From other similar means, the drug is characterized by the fact that it dissolves the scale and accumulated dirt at the molecular level, so colloidal particles do not clog the tubes of heating and cooling radiators. In addition, soft flushing ensures a pronounced passivation effect, slowing the formation of microcracks on the surface of the metal parts of the mechanism.

In addition to cleaning, the tool contributes to the maintenance of equipment in full purity for a long period of time, protecting it from corrosion. Another advantage of the drug lies in the fact that it can be combined with the most different cooling fluids.

The process of performing a soft flushing of the cooling system of the engine

Processing the device with this substance is necessary according to the following instructions:

Open the radiator cover on a pre-cooled engine, and then pump out a syringe 200 ml of antifreeze;
Capacity with soft flushing You need to shake and pour into the radiator, spin the lid back;
You must turn on the engine and start using the machine;
About 1500 km of mileage follows:
Completely merge the antifreeze, without giving the engine to cool;
Give antifreeze for several hours, and then 90% liquid pour back to the radiator, adding a new antifreeze (if the liquid is strongly dirty, then it must be changed completely).

Soft flushing is an excellent tool for maintaining the performance of the cooling system of the car. For getting excellent result Cleaning should be used only high-quality solutions. Otherwise, you can spoil the engine, which will result in additional cost-repairs.

Therefore, it is necessary to carefully choose a substance, paying attention to all characteristics of the solution.

Motor oil It is an integral engine element as other details. As the vehicle is used, the engine oil over time loses its properties, and accordingly it is necessary to replace it. There are also a number of reasons for which the replacement of the lubricant is simply necessary. You can change the oil both at home and in service centers.

In the engine exploited engine, there is a standard process for producing lubricant properties, as well as its pollution of wear by means of mechanisms and motors parts. There is a chance of getting into tosol lubrication, fuel and soot when combustion of the fuel mixture.

The car's service book indicates the recommended engine time without the bay new liquid. In order to change the oil, the periodicity of the replacement should be taken into account, which may depend on the motorcycles, the amount of fuel used or from the kilometers of the car.

Units, lubricants in which is carried out using the use of seasonal oils, need to be replaced twice a year. The properties of seasonal fluids depend on the temperature of the outer air. As a rule, in the spring and autumn periods, the engine washed when the oil is replaced. Drivers suggest that lubricants have different viscosity and exposure to the parts of the motor. Therefore, if it is not changed according to the season, it decreases significantly.

Required security measures

Car service (and in particular - Oil bay surgery) must be carried out according to all safety requirements. As a rule, immediately before the replacement, you need to give the engine a little cool, in order not to get injured in the form of thermal burn. All work must be carried out in gloves and respirator.

The main reasons for washing the engine

A common reason can be replaced by a fill type lubricant (Synthetic-semi-synthetic-mineral, seasonal-demi-season).
Changing the brand of oil manufacturer.
In suspected that water or fuel could get into it.
After purchasing a car with hands (to reduce the risk factor premature wear details).
After repairing the engine, and in particular - after dismantling the head of the cylinder block.
For visual inspection And the detection of a large amount of nagar on the details and larger sediment at the bottom of the pallet.

Methods and rinsing rules

At the moment there are several flushing methods:

Chemical.
Soft.
Full volume.
With the forced movement of flushing fluid.

On the degree of wear of the parts of the motor, the oil used and the operating conditions, the choice of the method depends on how to rinse the engine.

There is also a manual method of cleaning the motor from various clogging. At the same time, the engine must be disassembled with the use of vessels, various brushes and detergents manually clean the parts of the motor and mechanisms, as well as the block. This method of cleaning allows you to visually determine the presence of probable damage, more carefully diagnose parts and replace them, thereby preventing the possibility of more serious faults.

Chemical

This is the most common washing of the engine when replacing the oil. Reviews: an inexpensive way and is held in a short period of time with minimal financial costs. It is carried out quite simple.

In the old oil, pour wash and give the engine to work on idling About fifteen minutes. Then testing merges from the crankcase along with the washing. The use of this method is quite efficient, but at the same time it is not intended for cleaning motors with strong sediments and pollution. As experts advise, this method serves as excellent prevention from small diesel particulates and other deposits. Apply the chemical method is recommended each time at the moment of replacing the lubricant material.

Main part of Washing preparations are solvents, which, in turn, contribute to partial dissolution of mud sediments and give them mobility, and also raise the mud sediment from the pallet.

In the event that chemical cleaning power aggregate It is carried out regularly, the possibility of forming a dense layer of Gary on the walls of the crankcase is reduced to a minimum that, in turn, affects the wear of moving and contacting parts of the motor.

Soft

This method is carried out by adding a drug into a motor lubrication approximately 250-500 kilometers to replacement. The means for flushing the engine contains a smaller concentration of solvents, which does not affect viscosity and when using this method, mud deposits dissolve in oil gradually and at the same time acquire a fine structure, in the future mixed with the old agent. The disadvantage of the soft washing is the unpredictability of the consequences for a highly polluted unit. therefore this method Cleaning should be carried out with caution and periodic verification of the state of the fluid.

Full volume

It is more thorough and high-quality flushing Engine when replacing the oil. Reviews of this method are positive due to excellent performance at the end of flushing work. It is carried out as follows: The exhaust oil is drained from the engine crankcase, the plum plug is twisted on the pallet. Then, the engine is fused and run a motor for twenty minutes.

After that, the engine washing the engine is drained. And its remnants are removed by a vacuum installation. Replace oil filter And pour new oil.

With forced flushing movement

At the same time, the method of working is completely merged with the motor, the filter element is dismantled. Then the hose from the forced circulation device is fixed on the filter fitting. The second hose is attached to the plug-in neck, and the third to the drain hole in the block pan. A device for cleaning the motor is equipped with a container in which the engine flushing fluid is poured, and the filter. Under the influence of air pressure, the detergent enters the motor lubrication system, and the cleaning of the fluid is carried out through the device filter. Thus, all mud deposits of the engine are delayed in the tank of the filter element. Forced flushing is carried out on a non-working unit.

At the end of the washing, the filter is mounted on the engine, the process of full-volume washing with the start of the engine is 20 minutes.

Car maintenance in this way can take time within one hour. But at the same time the efficiency of the process is large enough. According to motorists' reviews, it is possible to clean even strong soot and gary raids, the intake oil grid is cleaned and all the oil channels of the block. The disadvantages of circulating washing with a compulsory method can be attributed to the moment of complete removal of the film of the lubricant material from the surfaces of the engine parts. This factor says that at the time of launch and in the first seconds of the engine operation, the mechanisms and motor nodes work without lubrication.

Depending on how the engine was washing, the service price will also be appropriate (from 3 to 5 thousand rubles).

If you decide to carry out the process of replacing the oil and washing the engine yourself, then initially determine the choice of flushing fluid. It must fit the type of oil that is flooded into the engine, as for synthetic and mineral oils exist different kinds Cleansing liquids. You should also consider the engine type - gasoline or diesel.

The detergent containers are usually indicated: the method of application, compliance with oils and engines, detailed instructions.

For better cleaning, it is also recommended to purchase an additional oil filter directly for the flushing process, after which it is dismantled and not used. To do this, it is quite enough to purchase a cheap filter element that is not sorry to throw out. This is necessary for cleaning the washing material and detention fractions of garbage.

If the engine itself does not seem to be possible, then you should contact professionals. Maintenance Station has a necessary set of equipment and tools for this event. At the same time, experts will be asked to hold any method of washing when the oil is replaced, also big choice Cleansing preparations.

Domestic motors

As a rule, the washing of the vase engine does not differ in the complexity of the process from the washing of power units of other manufacturers. The entire procedure for cleaning should be carried out according to the instructions, using a high-quality cleansing material and a properly selected, corresponding engine, engine oil brand.

Flushing of the fuel system of the gasoline engine

Many parts, knots and mechanisms of the car have their own working capacity and fitness resource, after which the items must be changed or producing them.

So, during the use of the car, regardless of the quality of the fuel, the elements are contaminated. fuel systemWhat affects operating modes power plant. New generation engines equipped with fuel injection system have a low tolerance threshold for fuel quality. Especially the motors with the distribution and direct injection of the working mixture. At the same time, small throughputs of the nozzles are often clogged with various foreign particles that are in the fuel. To prevent this type of malfunction in the system, various coarse filters use thin cleaningwhich are easily changed when clogged.

Since nozzles have the upper arrangement of the engine, they are affected by high temperatures.

Therefore, the probability of the formation of resinous deposits in the pump channels is very large. In the fuel of low quality there is an excessive percentage of heavy substances and sulfur, which affects this factor. In the process of clogging, the size of the nozzles channels are changed, thereby affecting the amount of transmitted fuel, up to the complete overlap and the moment of supplying the fuel mixture.

Fuel injector injection system gasoline motor It is a complex electromechanical device consisting of high-precision details that need permanent maintenance. The engine is performed in the order of planned and when the following problems occurs: the unit is badly launched, increased fuel consumption, micro-exhaust systems in the exhaust system, ignition switches in cylinders, reduction dynamic characteristics power unit, frequent failure oxygen sensor. At the same time, the flushing of the fuel system of the gasoline engine should be carried out on specially equipped stands, using high-quality washing material of the corresponding types and standards. Only with the use of high-precision equipment can be achieved high-quality repairs and excellent engine technical indicators.

What is washing liquid

The cleaning agent is made of non-very expensive engine oil (mineral), which add highcase and other active additives, which dissolve various negative sediments in the motor. All flushing can be divided into two categories of exposure: a long period of cleaning and the so-called "fifteen minutes".

Durable actions were widely used for approximately fifteen years ago. Such liquids were carried out during a certain period of time. At the same time, the car was operated only on washing oil, after which it was removed, and the usual engine oil was filled instead.

At the moment, this method of washing is used very rarely, which is associated with financial costs for the process. Another disadvantage is the restriction speed \u200b\u200bregime Auto.

The oil for cleaning the unit does not fully protect the contact details of the mechanism, which can lead to their failure. The disadvantages include the impact on rubber glands and seals of various chemical reactions occurring in the crankcase. With long-term use of this flush, rubber parts lose their properties and begin to collapse, which subsequently leads to more expensive repair.

More sparing is the fast flushing of the engine when the oil is replaced.

Owners of old cars with motors with big mileage Often are forced to use various engine cleaners, which in theory prolong the service life. However, disputes around the washing of motors will not die away. Someone believes that this operation harms the mechanism, although other drivers are confident in the opposite. Let's figure out what engine cleaners are whether the washing is effective and it is necessary at all. It is also appropriate to talk about the flushing of the fuel system. All this will be discussed below.

What are the engine cleaners?

To clean the motor from different sediments exist different methods and drugs. The very first and common is the method of full-volume washing. Note that this method is often used on a variety of one hundred, but its efficiency is low. If the old motor has thick oil sediments in the chambers, then there is no fully applied flushing. Need special chemicals and installation of forced recirculation. As for full-volume washing, it is simply performed.

The process of performing washing

To begin with, all oil from the oil system merges, then a special flushing oil is poured (or special fluid). Most often it is a simple cheap mineral oil with a large content of detergent additives. At the same time, the old oil filter is removed and the new one (preferably cheap, since it needs to be thrown after washing).

After refueling the washing oil and replacing the filter, the engine must be started and warm up for 10-15 minutes. After that, the exhaust oil can be merged. Most likely, it will be black and containing large dirt particles. The remnants of the waste liquid can be removed using a vacuum pump, which is practically in all professional workshops. Most drivers have no such equipment, so after removing the crankcase cover, it is desirable to wait about 20 minutes so that all the oil is completely merged. After that, it remains to put a new oil filter, close the crankcase cover and pour new oil.

In response, drivers indicate the effectiveness of the use of such a method on more or less new cars. Owners dirty motors Always remain unhappy with full-volume flushing and resort to aggressive means.

Soft flushing

In this method, a special engine cleaner is used (HI Gear, for example), which works in conjunction with old oil. It pours to the old oil. The composition of the soft engine cleaner includes solvent and detergent additives, but their content is small. System cleaning occurs slowly, so experts advise to add a flushing agent for 300-500 km to the oil replacement. And operational properties And the viscosity of the latter in the process of interaction with the cleaner does not change.

Judging by the reviews of car owners with old motors (with a large layer of deposits), such a flushing is ineffective for engines with significant mileage. In addition, there is a chance that such a flushing will cause a detachment of a large dirt particle, and that can clog some oil canal.

With regular use, this washing is not hazardous and suitable for not very dirty motors. After using the washing agent, the old oil is replaced, the residues of the lubricant are removed by a vacuum pump, and the new one is poured.

Chemical flushing

To implement it, a powerful aggressive means is used, which is poured into the engine before replacing the oil. Such drugs are usually called "five minutes" or "sevenminoths". They refuel the system (the old oil should be inside), give a motor to work for 10 minutes (there is an exact time on the package), drain the exhaust oil along with the preparation. The filter, of course, must be changed on a new one.

It is important before washing the motor and fill fresh lubricant to remove the remains of the old oil. Therefore, in any case you need vacuum pump. It is he who is more efficiently coping with this task. If you drain the oil from the crankcase, then not all the remains of aggressive chemical additive will be deleted. This engine cleaner is enough effective toolAnd it is recommended to use it systematically - after 2-3 oil replacements. In this case, the sediment layers will not be formed on the walls, and this will greatly increase the resource of the motor.

Does this motor harm?

In the reviews, car owners write that such an aggressive remedy has a destructive effect on the glands, which may tribal to flow after washing the motor. Therefore, it is necessary to choose a reliable engine cleaner. Gear, for example, provides sufficiently reliable soft and aggressive fluids. However, when using unknown manufacturers, the glands can really damage, and then they will have to be replaced with new ones.

Professional flushing

To perform professional flushing, a special installation is used to create forced circulation of lubrication via channels. With the help of a professional cleaner gasoline engines (and diesel too) can be effectively removed contaminated, without fearing the blockage of oil canals. At the same time, even the grid of the oil worker will remain clean.

Works installation as follows. An oil filter is removed, a waste oil is merged with the motor. The opening is screwed down with a hose from installation. The other hose is connected to the neck for the oil bay, the third fitting is connected to the oil drain hole.

A aggressive fluid is poured into the installation tank, and its this unit "chases" in a circle, effectively removing all the contaminants inside. All dirt is delayed on the filter of the installation itself and does not get back into the engine. Most often, such devices have transparent hoses in some places, and they can be seen as flushing fluid becomes black from dirt. This process It can be carried out within one hour, but it depends on the engine status. Such cleaning is extremely effective and suitable even for very dirty motors. Many owners of old cars in responses indicate that their motors acquire a new life after cleaning in this way.

Naturally, with such a flushing there is no need to run the engine, the installation itself pumps the required pressure and flips the dirt with the help of aggressive chemistry. After completion of the procedure, the engine must be rinsed again with the help of mineral washing oil. This is necessary in order to completely remove from the inside the aggressive substances that will definitely remain there. Well, and then you can already pour the "native" oil, change the filter and ride. Similar cleaners of diesel engines (and gasoline too) are on many hundred. Although this service is more expensive compared to standard cleaning, sometimes drivers have no choice.

Engine fuel system cleaners

In cleaning, not only the oil channels of the engine may need, but also the fuel system. When the engine is launched poorly, the problem may be in nozzles - it is sometimes necessary to wash them. This is done with the help of special fuel system cleaners. Liqui Molly, Hi-Gear, "Suprek", AutoProfi Line - All these manufacturers offer different means. They are added to gasoline in a certain ratio (always indicated on the package), as a result of which the composition of the combustible fluid changes slightly. In particular, the oxygen content in fuel increases. This indicates the presence of additional oxygenates, due to which the burning of fuel is improving. It is just necessary to clean the engine parts.

Result

Preparations really work. After their use, the motor functions better, the fuel consumption is reduced by 100 kilometers, and less residual hydrocarbons are detected in the exhaust. This is one of the most important indicators that determine the degree of pollution of the fuel system and the engine as a whole.

On the russian market Such drugs are inexpensive - their price on average is 300-400 rubles per bottle of capacity of 250-300 ml.

Do I need a long-term washing of the engine when replacing the oil? And does this problem be controvery? Mikhail Kolodochp and Professor of the St. Petersburg Polytechnic University Alexander Shabanov express their opinion.

To the question "How and why so wash?" Immediately added more global: how to change? Many believe - just merge and pour. Their opponents are confident that it is a direct path to the accelerated death of the motor and that the washing when changing the oil is required.

How to change oil

Options, how to change the oil, quite a lot. The easiest and cheapest is to merge or pump out the old and pour fresh. A more complex and expensive way to apply special flushing oil. A variety of five-ten-minute compounds, so-called short flushing are sold. This washing the engine before replacing the oil. They are recommended to pour themselves immediately before changing the oil and twist the motor for five to ten minutes on the minimum idle speed. And there are also drugs, conventionally referred to as "two sucksometer" or long. They are advised to fill over the week and ride with them the same 200 km.

New line of goods A-PROHIM ("Aprokhim")

During the first half of 2019 will be made phased replacement The goods of auto-chemistry "Supethek" and the commodity line, which was presented on a-proved.ru to a new, combined line. Buyers expect (the list will be replenished):

service tools: New silicone wax, universal metal cleaner based on brake cleaners, liquid key.

fuel additives: Fuel system cleaner with modified, more efficient formula and multifunctional Cleaning additives SGA and SDA.

purifiers: Disinfecting spray for cleaning the ventilation system and hand cleaner, long-term (soft) Wash engine.

plastic lubricants: The updated version of the reducing lubricants for bearings and hinges.

On the release time and the appearance of each new product in stores will be announced separately.

What option is better? We checked all the nuances of the theory and test techniques set forth in the sings. Compared not drugs different manufacturersand technology - they typed five.

To begin with, we act on the principle of "plin": the motor warms up to operating temperature, then stop and drains hot oil for 10 minutes; At the same time change the filter.

The following experiment is more difficult. After a drain, the motor was allowed, giving a minute to twist so much, - and some more dirty juicy came out of it. Next - see the first item.

Other experiments: We use two different flushing oils ("Onions .. l" and "av."), Then two short flushing ("High-g .." and "Auuto to ... P"), and then a couple Long - long-term flushing "Super Uprokhim"(not to be confused with additives!) And German "L ... and M.I" (). Results reduced to the table.

Gerontology of oil

Motor oil not only lubricates, it also removes wear products from the motor, mineral dust particles, traces of incomplete combustion of fuel. Therefore, dirt in oil is normal.

As it develops oil, its main indicators change. The viscosity on which the ability of oil is depends on to form layers separating work surfaces will grow. Alkaline number falls: clean additives are triggered. And the acid number falls: it reflects the accumulation of its oxidation products in oil. Dispersing ability (on it judges how oil holds pollution) with an increase in the operation decreases. When some of these parameters go beyond the specified, the oil becomes some kind.

It is clear that this alien must be merged. But it alters it is not all - the residue is cut in the hidden cavities, on the walls of the engine, etc. The value of the residue depends on the properties of the waste oil, the engine design, oil temperature before the drain.

Up to 15-20% of the old oil is mixed when changing with fresh, worsening its initial characteristics.

Moreover, during the operation of oil in the engine, deposits are formed. High temperature deposits are varnishes, settlement in the area piston rings On the side surface of the piston. And the low-temperature will be found in the pallet, in lubricating channels, on the details of the gas distribution mechanism. When changing the portion of oil, they must be removed from the maximum and - Attention! - Do not harm at the same time the motor: washed sediments capable of tightly clog the oil system channels.

Well-being after bath

The "Slip-flooded" procedure significantly worsened the parameters of fresh oil. Its resource is clearly reduced. As far as I do not say, but in our case, the state of the new oil according to alkaline and acid numbers was approximately as we watched it in the experiments of a pair of thousand kilometers of mileage. And the viscosity increased: "Thank you" to thick precipitation ...

Blowing the engine on the minimum idle turnover before the fill of fresh portions has improved the situation, but not much. Yes, dirty oil is extruded from the channels, but on the walls and in the hidden cavities will still remain.

Now - washing oils. After draining the workout and fill the washing product, the motor every time was allowed to work 20 minutes, then dropping and refueling with fresh oil. The deterioration of alkaline and acid numbers has become less. Viscosity due to flushing residues in the motor slightly fell, but it will not affect further operation. The mass of deposits decreased noticeably. However, it is still far from cleaning. But the metal content has decreased significantly.

In turn short Flushing of the gasoline engine.It was poured to the drain of the old oil, while the engine was completely warm. Then he was chased 10 minutes on minimal idle speed. Analysis of residual pollution of fresh oil and the weight analysis of the control elements revealed a very decent effectiveness of these compositions. But the complete drain was still failed to achieve, and the fresh oil became slightly less viscous.

After autopsy, the pallet found small fragments of deposits, obviously removed from the walls with detergent components. It means that wash engine Effectively flaps sediments, but does not dissolve them. And if they block the channels, then wait for the bearings!

Came Long / long-term washing. They screwed up an analogue of 200 km of run in different load modes. The viscosity has decreased, but within reasonable limits. After the arrival, they opened, looked ... pieces of "breed", which were previously observed, was not in the pallet - dissolved! This is a big plus. The quality of fresh oil after using long washing deteriorated slightly. Note here Long-term flushingsuitable I. for diesel engine And for gasoline.

Wash or wash?

Those who from the very beginning was only one thing - wash or not washed, we set out your opinion.

Motor is not necessary to wash the one who:

applies good oil And changes it according to the "buckle" of the car without a substantial root. The remnants of such an oil, in our experience, still quite augment and packages do not make it.

Motor is preferably to wash the one who:

goes to a higher class (for example, with mineral water on synthetics). The table shows how much the viscosity index asked - the main decoration of synthetics - after contact with the remains of the old oil;
allowing significant trials over the required replacement period;
i revealed or implies the fact of overheating and whether a sharp increase in foam;
uses incomprehensible origin oil (for example, when it buys a car in the secondary market).

Currently, several methods for washing the engine lubrication system are applied:

chemical;
soft flushing;
full-volume washing;
washing using the installation of forced fluid circulation.

Chemical (The most common abroad) method: The remedy is poured into the exhaust oil immediately before replacement and after 10-15 minutes of the engine at idle is merged with oil. Contrary to popular belief, the chemical method works efficiently, but at the same time it is not intended for the "treatment" of a fully contaminated engine, but only for periodic prophylaxis. The chemical method is used for each oil replacement or after a few, to remove small coke and other sediments. Thus, the accumulation of a nagar layer and deposits on the engine parts is excluded, and the oil sucks in the engine crankcase is not allowed.

The basis of drugs is chemical compounds - solvents that are guided by a specific type of deposits. When using such funds in a highly polluted sediment engine, coke and other garbage acquire "mobility". Some sediments in the oil filter can also dissolve. When merging the exhaust oil in the engine, up to 10% of the lubricant remains, and this "movable" residue can score the oil grid, significantly limiting the oil supply into the lubrication system of the entire engine. In some modern engines Constructively provides a mesh in oil channels ( Honda CR-V), But if she also breaks, oil starvation will arise. The sound of the engine in this case reports the need for overhaul.

Conclusion - if it is known that the oil replacement was carried out regularly, and the oil was applied to the appropriate quality, it is possible to periodically use chemical flushing. If the engine is heavily polluted, or its previous life is a dark past, rinse the oil system is needed with a new filter, with a mandatory pumping of the vacuum installation of the unsalted residue. To achieve a guaranteed result, it is better to remove the engine crankcase pallet, clear it from the inside and the grid of the oil worker and, if possible, blow oil channels with compressed air through the holes supplying the oil to the filter and removing from it. This will help prevent sad consequences.

Soft Flushing is carried out by adding the drug to the oil for 200-500 km of mileage before replacement. It also contains solvents, but their concentration is less, and the washing itself does not change the viscosity of the oil. With this method, the contamination dissolve gradually, and also gradually go into a fine form, even merging with the exhaust oil. But the effects of soft flushing for a strongly contaminated motor are unpredictable, and this method must be used with caution.

Full volume Flushing is most common to one hundred Irkutsk. In this case, the method of spent oil merges, and instead it is flushing, on which the engine runs 10-20 minutes. After that, the washing merges, on some one hundred years is removed by a vacuum, the oil filter changes and the new oil is poured. Some hundred in Irkutsk with this washing method are used by Korean filters. That is, before the fill of the full-volume washing, the filter is replaced with the Korean filter, and after, before the fill of the oil, they change it to the corporate or just Japanese. Such a procedure even with a strongly contaminated engine reduces the likelihood of sad consequences, but not too effectively rinsing the oil system. Purpose - flush weak deposits at regular use. In a strongly contaminated engine, efficiency is minimal.

Flushing S. forced circulation of washing liquid. Exhaust oil merges from the engine, the oil filter is removed. Instead of an oil filter through an adapter joins the hose from the installation, the second hose is connected to the oil-tapping neck, the third to the drain opening of the crankcase. Installation has a container with detergent liquid and its own filter. Air pressure washing liquid is supplied to the engine oil system in the "straight" and "reverse" directions, and in the circulation process passes through the installation filter, leaving dissolved sediments there. The engine is not started with this method. After washing, a Korean filter is put, a full-volume washing is poured, and the engine is started for several minutes to completely remove the aggressive flushing. The process can last about an hour, but it is quite effective, does not leave deposits in oil channels and flushes pollution from the oil grid. Especially recommended for highly contaminated diesel engines. But this method has one unpleasant moment - the flushing fluid is completely flushes with the finest oil film from the details, and with the subsequent startup, the engine works "dry" for some time. All other means are completely oil film not delete.

Unambiguous answer to the question "wash or not washed" no, but in russian conditionswhen most of Transport has a significant mileage, oils have various bases and additive packages, unknown quality filters and, which is very important, fuel, and many cars often move from hand to hand, wash can be considered an effective way to maintain the engine in the normal state. On the most hundred years of oil replacement, it is strongly recommended. This, although it does not guarantee from subsequent trouble, but reduces their probability. Selecting the method of washing and in general, the decision to carry out this procedure remains behind the car owner.
