Improving engine oil: gasoline in the crankcase. What if the oil smells like a gasoline? In the injection motor in oil gasoline

This post is 1 comment.

Many car owners periodically faced the fact that the oil probe smells like a gasoline. Since the smell is all different, knowing motorists They advise one simple additional manipulation: move away from the car and try to spend the dipstick over the flame of the lighter. If the smell did not fail and the remains of gasoline are on the dipstick - a small flame will appear, testifying to the burning of fuel vapor. You can go to another way, without using a lighter: a drop of oil is put on a blank sheet of paper. If gasoline is - a drop of diameter begins to spread, wetting the paper. If there is no gasoline - oil remains in initial formHis viscosity will not give a drop to spread and wet the paper base.

Why oil probe smells like gasoline?

Possible causes: mechanical gas station is faulty; Malfunction of nozzles, or a malfunction of the piston system. In the first case, the gas station is removed and the pumping lever pumps gasoline. Appearing on the wall of the engine of the engine or sharply amplifying smell of gasoline - evidence that the aperture of the fuel pump lost hermeticity. Elimination of this problem is possible in two ways, one of which is fast, but gives a short-term effect, it is adding several layers of cellophane into the diaphragm. And a more reliable option, it is a replacement of a fuel pump for a new one.

Nozzle malfunction.

How to determine the nozzle faults: Connect the pressure gauge and check the power supply pressure, determine the upper limit and for at least five minutes you will observe the change in the testimony of the pressure gauge. If the appliance arrow shifts to a decrease in the indicator, then the fuel comes through the faulty nozzles. Run the engine and, as soon as the optimal pressure in the power system is scored, disconnect the ignition. Now you will visually determine which of the nozzles is faulty (roughly spraying fuel). Faulty nozzles change to new or clean special tool, ultrasound (only in a hundred). If we visually determine the quality of spraying the fuel injectors fails, use plastic disposable cups, putting one by one for each of the nozzles. By a subsoil on the wall of the cup, you can determine which of the nozzles works faulty and clean it or replace it.

The cause of the smell can be a malfunction of the piston system.

Repair this problem is the most expensive and complicated. And most often this problem occurs when using low-quality oil or fuel. Poor-quality lubricating and fuel products leads to a climbing of the piston rings, as a result of which the fuel will be disappeared through the gaps resulting between the piston and the walls of the cylinder and enters the oil.

To identify this problem, you will need a compressometer. The compressometer is measured by the compression indicators of each cylinder. The difference in more than 10% of the norms specified by the manufacturer, speaks of a malfunction. Focused piston rings are washed specially designed for this chemicalsAfter which the oil change is required. In rare cases, the flushing does not help, then the engine is disassembled and the defective pistons are replaced.

Supplement the author of the article. Gasoline into the oil can also get from an incorrectly working spark plug. It happens, you buy candles in the store, check them, everything seems fine. And under pressure in the cylinders, they do not perfect their functions. Gasoline does not burn, falls into the pallet with small. Therefore, the ignition candles store must be checked under pressure. For this they have a special stand. On the carburetor engines The reason for the fall of gasoline to the oil can not be the tightness of the needle of the float chamber. The fuel mixture is obtained enriched and well combines in the engine cylinders. The problem is solved by the replacement of the needle. If the gasoline situation in oil is solved, then the engine oil and filter should be replaced. Such oil lost its lubricating properties and can lead to engine jamming. And this is a major overhaul, which is worth it.

In vehicles equipped with an injector, fuel injection is carried out under pressure using special nozzles. If gasoline gets into the engine oil, you need to look for a breakdown.

About gasoline in lubricant can be judged by such factors:

1. Motor liquid has become less viscous.
2. Lubricant with probe flashes. Butter, without extraneous impurities, it is practically not lit, if it is mixed with a fuel, then it's easy to check it enough. Probe, with some number motor fluid Run to the flame lighters. If there is a gasoline lubricant - the probe will be a bright flash.
3. Increased fuel consumption.
4. Reducing the power of the power unit.
5. The appearance of extraneous noise in the motor.
6. A drop of oil, taken from the probe, when applied to a napkin or paper forms around itself a zone from a transparent material that quickly evaporates.

If one is present, do not panic from the specified signs, try to find yourself and eliminate the cause.

We independently find and eliminate the causes of breakage

The presence of fuel in the engine fluid can be judged by the smell of oil taken from the probe, it begins to smell fuel. Letters of this there is a violation of such nodes:

1. Ignition systems. If one of the ignition candles ceases to work - the fuel-air mixture coming to the cylinder does not flammify and does not perform useful work, part of the gasoline is settled on the cylinder, then flows to the Carder, so the corresponding nasty smell. To eliminate this reason, check each of the candles.
2. Injector nozzles. If nozzles are not tightly closed, then when the motor is stopped, some fuel volume with residual pressure falls to the collector, then to the cylinders. You can eliminate the breakdown by checking the nozzles for tightness, feeding the liquid to flushing the nozzles from the spray. Replace leaking nozzles.
3. Electric pump. With it, fuel is injected. If the pump malfunction, the fuel pressure in the system is very low - nozzles do not spray gasoline, and pour. The degraded spraying leads to a poor-quality mixture of fuel with air, which causes poor fire, due to which gasoline burns not completely and its volume is seeping through the rings into the oil. Inspect the pump gaskets, if there are mechanical damage on them, cracks replace the gaskets with new ones.

Unscrupulous fuel manufacturers, wanting to save, add to gasoline low-quality additives to increase octane number. Thus, they increase their profits. The use of the specified fuel leads to a deterioration in the work of the spark plugs and the electric pump. Inspect the candles, flashing red on them means: Pointed low-quality fuel.

Causes requiring specialist intervention

The most unpleasant cause of gasoline getting into the engine oil with an injector there is a malfunction piston group. It is possible to deformation of the walls of the cylinders, the presence of cracks on them, scratches or chips. With prolonged use of oil with bad detergent properties, the oil surgery rings are climbing.

Determine the breakdown, measuring compression in each of the cylinders. Measures may differ from each other by one unit. With a greater breaking of compression values, you can talk about a malfunction in the specified cylinder. With such a situation, do without overhaul The engine is impossible.

You can try focusing masonry rings Restore, using special chemicals, but there is no good effect from such manipulations.

Let's summarize

The causes of gasoline in the lubricant Machine Machine Machine equipped with an injector are as follows:

1. Fault of the ignition system
2. Wear injector nozzles.
3. Violation of the gas station.
4. Locking, clocking of the oilmaging rings.
5. Malfunction of the piston system.
6. The use of low-quality fuel.

The last of the reasons is the most cunning. Gasoline is an aggressive chemical mixture with a certain amount of various additives, which should not be contacted with engine oil of cars equipped with an injector: it can change properties lubricant, It will destroy its structure - this will lead to drive breakage. Noticing the admixture of gasoline in the engine fluid, eliminate the cause of such a situation, then replace the engine mixture.

Many motorists faced an unpleasant fact when the oil is filled with the smell of gasoline. If the smell does not disappear, then you need to pay special attention and find out the reason for the occurrence of such an effect. As a rule, the cause of the phenomenon is a malfunction of the transport motor. Therefore, it is necessary to immediately visit the wizard having special equipmentor auto service - to diagnose system performance.

Leave such a defect in the state "as it is". The gasoline entering the lubricating component means a malfunction of the power unit, and this leads to the overflow of the fuel and its breakdown.

The essence of the problem

With a normally running engine, the fuel system does not come into contact with the space of lubricating elements by which oil comes with. That is, gasoline should not be in contact with oil. Find out if the gasoline component falls into the oil system, just enough. To do this, get the control probe from the oil system and check on the smell.

If the smell fails, then with the dipstream, you should move away from the car as far as possible and bring a match to it (pre-lit). The oil in its pure form is rapidly not ignited, but the mixture of petroleum products flashes brightly. Also check the availability of gasoline in oil by dripping water drops. If a rainbow shell appears on the surface of the water, then a certain part of the fuel is present in the oil.

There are a number of secondary factors that indicate the leakage of petroleum products from the fuel space:

• increased gasoline consumption;
• reduction of engine power indicators;
• transformation of the shade of oil and smell;
• the emergence of an unusual sound in the piston space;
• the volume of the cooler.

If any of the signs occur, it is recommended to contact the car service. Although in certain knowledge this question can be solved on their own. The presence of the fuel cell in the oil indicates the presence of some defects. The causes of the occurrence are a malfunction in the fuel supply pump, damage to the nozzle, damage in the piston space. For restoration work, the following tool will be required:

• Pressure meter, which comes complete with the fitting;
• Compressometer;
• A set of various keys and devices;
• Electrical measuring device;

As well as tissue and solution to remove contaminants.

Any preparation procedure provides for cleaning the surface in place. repair work. Next, remove the gasoline pump, turning the fastener bolts. The wires of the leaving and supplying type are recommended not to touch, but if they interfere with when working, you should remove them and secure the plug so that the fuel does not flow.

The next step is to wear the wires on the fittings and clamping clamps for fixing. Withdogging rubber gasoline with clamp. But if the pipe is made of metal, then it is required to disconnect it from the carburetor system and shut a tight plug.

After that, the fuel is pumped in the engine with a manual type pumping lever. If a gasoline in oil appears on the motor side, or a sharp smell occurs, then the aperture of the fuel tube is notch.

Further work can be carried out in two scenarios. To the first one refers to the replacement of the old type of wire to the new one, to the second - the restoration of the benzier. Do not forget that the analysis and collecting gasoline pump should be carried out in accordance with technical recommendation manufacturer on the vehicle.

If the car owner has a set of auto parts for repair work, it is recommended to change all the corresponding parts, including pneumatic and valves. The filtration grid must be thoroughly cleaned in the solvent. At the end of the collection of design, a test launch of the performance of the system and the closing density of the diaphragm is performed.

After completion of the repair, it will be necessary to closely monitor the control of oil, especially with a hint and level, for confidence that everything is done correctly.

There are situations when one or several nozzle elements are notometric, as a result of which fuel can be faced in the cylindrical system and through the gaps in the space of the pistons. To confirm these concerns, you need to use the pressure meter with a rubber hose and the configurator to the fuel rail. The maximum pressure of the pressure gauge pressure is no less than 6 kgf / cm 2.

Connect the configurator to the fuel rail, and the pressure instrument to the adapter and turn the ignition. If the fuel pump is normally started, it should be waited a little when the pressure in the rail is stabilized. Next, you can turn off the ignition. If the fuel pump is not operational when the ignition is turned on, then the engine is required. Next, we carry out control over the pressure surge until the optimal value, after which we drown out the engine and turn off the ignition.

Within a few minutes, you should monitor the values \u200b\u200bof the pressure gauge. If the pointer in the device is shifted to the left side of a quarter or more, then this means a failure in the gasoline supplied system. After detecting a defect you want to remove the rail fuel system From the sprayer and make a thorough inspection.

Nozzles We place in conventional glasses from the store, the volume in the floor of the liter, and the fuel tubes and the connections of the electrocurity should be connected at this time. Turn on the ignition. During the scrolling, we estimate the visual effect of the fuel sprayer. Having achieved optimal pressure revolutions in the supply system, ignition should be turned off. We look again and control the operation of the nozzles on the sublifting. If the leakage is detected on these elements, it is necessary to measure the resistance of the windings with a special device.

The nominal value of the resistance is at the level of 10-14 ohms. If the instrument indicators do not coincide with these values, the nozzle leaks. In this case, the replacement of the nozzle is necessary, but only in accordance with the regulations on the management of transport.

Disorder in the piston system

This malfunction is the most cost of all existing ones. If low-quality raw materials are used in the car, then the formation of slag on pistons and wear of the corresponding rings that have lost the indicators of elasticity are possible. It is also possible to form gaps through which the leakage of incoming gasoline occurs.

As a result of this phenomenon, the piston became a leakage. Diagnose this defect is elementary - it is recommended to twist the candle and put in the hole to shove ordinary paper. Next, turn the engine starter. If the paper cork does not remain in place, it will mean that the compression is present. This method is effective when there is a significant loss of compression in the engine. To determine small losses, it will require the use of a special compressometer, which will identify even the smallest loss of compression loss.

The device is a device similar to a manometer, but it has a metal tube with a rubber part and a check valve. Diagnostics are better to produce together. If the engine is carburetor, then all the candles should be turned out. After that, the compressor is connected to any of the cylinders and the engine rotation is rotated. It is necessary to do this while the shooting of the arrows will stop moving into an increase in the values \u200b\u200bof the device.

The limit value of the device will mean the compression of the cylinder. Next, similar manipulations are performed on other cylinders, the indicators are fixed. If values \u200b\u200bdiffer from the data set by the manufacturer, more than ten percent, or different between the cylinders, then you need to make damage to eliminate damage. On the injection type machines, turn off the fuel pump before diagnosis.

Motorists in their mass, as a rule, never pay attention to the smell of oil. And it can smell gasoline. It is necessary to know that if such a smell appeared, then it is necessary to establish the reason for its occurrence. Since this suggests that, with a great degree of probability, a malfunction appeared in the car engine.

The essence of the problem

In the working engine, the lubricant system in which the oil circulates is isolated from the fuel system. As a result, it cannot penetrate oil. However, if this happened, the oil control probe will exhibit the gasoline smell (oil smells with gasoline).

If the driver does not believe its sense of smell, the presence of gasoline on the dipstick is quite simple. To do this, you need to move away from the car for a sufficient distance and affect the probe by open fire by means of a lit match or lighter. The presence of gasoline is determined by the flash, while pure oil It will light up very slowly.

Auto mechanics, as well as motorists with experience advise to check the oil level once a week. System and permanent checks will allow reveal a decrease in the oil level in the engine. And also to evaluate its condition.

If the oil is in acceptable boundaries, but its color and consistency have changed, the smell appeared, oil smells with gasoline, then these are signs indicating the need to diagnose internal combustion engine.

Gasoline may appear in oil even in the engine, which has a completely working cylinder-piston system. However, if the engine oil smells like a gasoline, then this is considered to be serious. It may entail failures in the operation of the motor, reduce its life, and also lead to its full breakdown.

When gasoline gets into the oil, it begins to lose its properties, becomes more liquid. The more gasoline penetrated into oil CarterMoreover, there will be damage.

The main signs of the appearance of gasoline in oil

Specialists in the signs indicating the emergence of the problem of fuel penetration into lubricant include the following:

• The engine begins to lose power, increases noticeably fuel consumption.
• Exhaust system Gives a gray and thick exhaust, in which there is a smell of gasoline.
• The engine begins to make failures, told, periodically stuck.
• The engine work has become noticeably louder, the knocks in the piston system are recorded, in the area of \u200b\u200bfinding crankshaft and other engine nodes.
• Oil probe shows that the oils in the crankcase became greater, the engine oil smells like a gasoline, which is clearly captured.
• The oil has become more liquid, his drop with the probe calmly flammives from open fire.

METHOD OF QUALITY QUALITY OIL

There is a way to check the quality of oil. It is used including when checking on the presence of gasoline in it. The method is called "oil stain". When using it on a sheet of paper, one drop of oil from the probe is dripped. Paper dried about 2 hours. If the edges of the spreader drop smooth, then this reports that the oil does not lose their properties. The black contour in the central part of the spot indicates that the lubricant has operational additives. This method is used to assess the qualitative condition of the oil, establishing the presence of other inclusions in it, including water and gasoline.

It is worth understanding that fuel (gasoline) is an aggressive product in relation to oil. It includes a significant number of varied chemical additives and additives. Engine oil also has additives, and they should not contact with fuel. If the contact of gasoline and oil occurred, then it should be understood that at the same time irreversible changes in the physical and chemical parameters of the engine lubrication occur. As a result, if in the Carter oil level increases due to fuel ingress, this is a serious threat to the motor's motor.

But why oil smells gasoline? To answer this question, it is necessary to understand how it falls there.

Ways of gasoline to oil

To understand why gasoline penetrates the motor lubrication, it is required to obtain an idea of \u200b\u200bthe design of the internal combustion engine.

1. The main way to penetrate gasoline into the engine crankcase from the combustion chamber (both injector and on carburetor engines) are piston rings. Frequently often gasoline falls into the crankcase on new engines. When the piston rings are not yet fit, there are loyal in the cylinders.
2. The engines equipped with a carburetor have a weak link is a fuel pump aperture. If it is deformed or has a different defect, then gasoline will definitely penetrate the engine lubricant. Other reasons include problems with a needle carburetor valve, a valve of the float chamber, fuel overflows, etc.

Causes of oil pollution with fuel

It follows from this that the main reason for dilution of gasoline oil is problems in the system of nutrition and ignition either in the engine itself. Systematizing all reasons, you can get the following picture:

• the working fuel mixture is subjected to re-enrollment;
• faulty nozzles, carburetor, fuel pump;
• there are malfunctions of the ignition system, it works incorrectly;
• the engine is worn, there is no compression in the cylinders, the fuel ignition does not occur.

Due to the above reasons, fuel is fed to the combustion chamber in excess. This leads to the fact that it is concerned and cannot ignite. The fuel does not burn in particular due to the lack of spark on the ignition candle or due to small compression.

Fuel, which is not burned, penetrates the oil crankcase.

In any case, if the fuel penetrates into the oil, the engine is not recommended to exploit until the causes and elimination of the problem. This is especially dangerous if the driver does not know about the problem, and a significant amount of fuel has accumulated in the crankcase. Pressure in the lubrication system falls, dashboard Signals an emergency condition of oil pressure.

With such a situation, it is necessary to immediately take steps to eliminate the main problems. This is done at stations that are engaged in the repair of the ignition system, carburetor, injection injection. Be sure to replace the oil and oil filters. If after that there are no signs that the engine in the engine smells with gasoline, the reason is eliminated.

Fault of gas station

In the car, which is equipped with a mechanical benzonasosos, its diaphragm pumps gasoline directly into the carburetor. However, if it is damaged, overshadowed, fuel paves the path to the rod canals. The pump of the pump is driven by an eccentric, which is involved in the distribution of oil in the engine. Therefore, gasoline easily finds itself a way to the oil environment. You can identify this problem by learning the smell of fuel on the dipstick (oil smells with gasoline). If the diaphragm damage is insignificant, the lubrication level can remain the same for a long time. However, with significant gaps, gasoline no longer goes into the carburetor in the required quantities, the car starts with difficulty, its movement occurs with jerks. Usually, the fault is eliminated by replacing the diaphragm to a new, which is included in the standard repair kit of the fuel pump. If when checking after repair it is not found that the oil in the motor smells like a gasoline, then the problem was solved.

Malfunction of nozzles

If the engine is an injection system and if the oil smells like a gasoline, the reason is that there are problems with nozzles or the ignition system. Nozzles, one or more, do not provide hermetic closing. After turning off the engine, the fuel due to the residual pressure penetrates the collector, and then into the cylinders. If the piston rings are not worn, then gasoline will not fall into the crankcase. But if they are operated for a long time, there is a rings, they will not be able to prevent gasoline leakage into the oil crankcase. To eliminate this malfunction, it is recommended to remove the fuel ramp and check each nozzle for tightness. In this case, kerosene or special fluid From aerosol cylinders. If nooking is installed, as well as damage to the candles, they are replaced with serviceable.

Fault of a piston system

The elimination of this problem is considered the most expensive and difficult. Usually this fault occurs if low-quality oil and gasoline are used. Low-grade fuel and lubricants lead to the fact that the piston rings are locked. The fuel begins to leak through the gaps that occur between the piston and the walls of the cylinder. Then it gets into the oil crankcase.

To identify the specified malfunction, the application of the compressor will be used. They measure data on the compression of cylinders, each separately. If the readings differ more than ten percent of the established norms, this indicates the presence of a malfunction. Piston ringsPurchased, is washed, is washed with chemicals specially designed for these purposes. Replacing the oil after such a procedure is required. Typically, the engine oil does not smell gasoline after such a procedure. If the flushing of the cylinder block did not help, which happens infrequently, then the engine disassembly in order to replace faulty rings and pistons.

Embossed fuel

Sometimes the cause of incomplete combustion fuel mixes In the cylinders is the gasoline itself. It is not uncommon that at filling stations the quality of fuel leaves much to be desired. Moreover, gasoline can be mixed with other additives, due to which it is harder to ignite. Unburned fuel mixture residues penetrate the engine crankcase. In these cases, it is necessary to start using another gas station to eliminate the problem, but the oil will still have to replace.

Separate specialists are advised to prevent when traveling to free tracks to give the Motor to work a slight time at high speed. This way of driving leads to more high temperatures Heating oil. This reduces the amount of condensate accumulated in the lubricant and hitting gasoline oil.

How is gasoline in the oil? When using the car, sometimes trouble happens. It is based on the situation when gasoline gets into the oil. This can turn into faults, car outlet.

In order to prevent this, it is necessary to understand what the cause of gasoline in the oil is caused.

What is the danger of mixing fuel with lubricant

When gasoline falls into engine oil, it starts complex reactions, as a result, leading to different damage. It is necessary to add that it all depends on the volume of fuel, which turned out to be in the engine oil. If it is small, the motor will normally work a little more. However, serious malfunctions will still appear. If gasoline in the crankcase is present in large quantities, it quickly leads to the vehicle breakdowns.

The effect of gasoline penetration into the oil:

• violation of the fuel coefficient of correction. The power unit sometimes cannot be started;
• reducing the speed of driving, the car hardly develops the maximum speed;
• piston breakdowns appear;
• output engine output. This happens when the carburetor, injectors are damaged.

How to determine what is a malfunction in the car? You need to pay attention to certain signs:

• increased fuel costs. Gasoline is spent quickly due to the fact that some of its part flows into the engine to the lubricant;
• strong tapping, noise in the piston system. This is evidence that fuel processing is broken;
• the power of the motor decreases, the car is more difficult to travel to the elevation;
• oil color changes;
• falls the coolant level.

What if you noticed one of the above signs? Immediately go to the car service.

How fuel penetrates the crankcase with lubrication

Gasoline falls into Carter in such ways:

1. By means of the main oil pump. The lower area of \u200b\u200bthe pumping diaphragm prevents the top of the harmful vapor of gas from the crankcase. It is sometimes possible to check the state of the diaphragm.
2. Through a carburetor. This happens if the needle valve is broken. The car is overloaded, it leads to high fuel costs.

In order to under the carburetor, the glass fuel was accumulated, it is necessary to display it through a special drainage tube embedded in the collector. If the tube clogs, excess fuel will be on the engine cylinders. If the temperature is large, they will almost immediately evaporate. With a cold start of the engine in winter, especially in a strong frost, fuel will flow through the walls in the crankcase. This will lead to the formation of a mixture of gasoline and oil.

It often happens that the driver does not suspect the penetration of fuel in the lubricant until the high pressure indicator in the oil complex does not light up on the instrument panel.

Low-quality gasoline

Fuel can be found in lubricant due to its own low quality. Why does quality matter?

The car owner often buys fuel, which has a variety of added additives (benzene, toluene). It can quickly penetrate the lubricant due to the substances added. The car, which had an influence of a bad fuel, rapidly worsens its own characteristics. This brings the fuel distribution node to faults.

In view of this, to eliminate the problem, sometimes quite simply change gasoline. We must carefully choose fuel. Immediately replace it if we noticed that the oil was smelled with gasoline.

Elimination of the problem

When smells of gasoline are felt in oil, it is usually recommended to go to the car service. If everything goes too far, there is no other way out.

However, at the beginning, when there are no significant car malfunctions, the driver has the ability to eliminate malfunctions. To do this, you need to quickly drive a couple of kilometers by car, then perform lubrication plums, check whether there is gasoline in oil. If it is not, it means you managed to get rid of the smell of gasoline.

Foreign manufacturers recommend that it is to diagnose the car. We often leave on the highway for discharge of extra fuel. Thanks to this, you will be able to get rid of the problem at the very beginning, prevent the emergence of significant breakdowns. You do not have to spend money on expensive repair work.

Fuel in a lubricant complex

Masters like foreign cars and russian cars Known the problem of the appearance of gasoline smell from the car. In the two-stroke power unit, fuel is a combination of gasoline and lubrication. In a four-stroke engine, these liquids should not come into contact. Oil circulates closed. If there is a smell of gasoline on the dipstick, it means that the fuel mixed with the car.

Signs of leakage

Is it possible to understand what happened to the leak? It is possible to know about it, noting the dark puddle under the car. It happens that the lubricant follows from under the lining of the valve cover, the glands or curtain gasket. The machine can be mixed with fuel only in the motor. Determine that gasoline got into oil fluidmaybe in such signs:

• changed the viscosity of the oil, it was gone;
• machine on the dipstick lights up, if you bring the flame;
• oil droplets on a piece of paper leaves a fat increasing stain.

Causes of leakage

Fuel, regardless of the type of power supply system, after a gasoline pump should reach a carburetor and combustion chamber. The latter presents the part of the GBC (the head of the cylinder block) and the piston head, where the combustion of fuel and oxygen is combustion. A mixture of fuel and air on the way to the combustion chamber passes the channels inlet, their necks are always lubricated by car. Here there are leaks. The reason lies in the fact that the valves are equipped with rubber caps. They are designed to reflect the car. If, due to the strong wear of the caps, the lubricant will penetrate into the combustion chamber, the exhaust cars will become smoke from motorcycles. The chance that the car will fall into the combustion chamber, rather low. Usually oil smells with gasoline for other reasons.

It is worth adding that if you start a car in winter conditions, gasoline 1st a couple of minutes will burn inefficiently. Traffic fumes It smells raw fuel, condensate flows from the exhaust pipe. This is completely normal.

Injector nozzles

In the engine with the injectors of the smell of gasoline, which comes from the probe, testifies to breakage of the nozzles, the ignition system. In the 1st case, we are talking about the nozzles lose due tightness. After turning off the fuel engine, due to the residual pressure, it seeps into the collector, it penetrates the cylinder block. The piston rings serve as a barrier on the way to Carter, however, if they are worn, gasoline will still fall there.

Gasoline smells also with faulty system ignition. If the candle broke, it does not flash fuel in the cylinder block, then you are spent just so. To eliminate the problem, it is necessary to remove the fuel ramp, in turn to check the tightness of all the nozzles by supplying the kerosene in them. The flowing parts and broken candles must be changed to others.

Common problems

The main reason for which the car is in contact with flammable is a strong wear of compression / oiling rings. Gasoline breaks into the crankcase, the oil enters the combustion chamber. All this indicates that it is necessary to overhaul to repair force aggregateSince it has accumulated many serious faults.

The motor becomes much weaker if the compression is reduced at least one cylinder. Superior fuel in the combustion chamber also does not lead to anything good. Cartoon sediments will increase, the motor will constantly overheat. Consequently, viscosity automotive lubricant will change. In other words, the oil will become diluted. It is unsafe for the engine operating in high revs, in harsh operating conditions.

The consequences of any malfunction can be minimized if you detect the problem in time. It is necessary to pay attention to the above leakage signs. Then you do not have to go to the car service so that there is a complete repair of the engine of the machine. This service is quite expensive, so it is better to know what the main signs of fuel from the oil fluid. This will give the opportunity to avoid many significant cash costs.
