Black smoke from the exhaust pipe - causes, consequences and solutions. Why is black smoke from the silencer causes black smoke from exhaust

Consider the situation when carburetor Engine a passenger car Small smoke smoke. Namely, the causes of this phenomenon associated with the carburetor malfunction. Why appears blue smoke Described in another article on this topic -, white smoke.

Of exhaust pipe The car comes out black or dark gray smoke. The smoke can be of varying degrees from strong, to weak. Feeling smell of gasoline. Possible to the silencer. And the engine work is not stable. Fall and on the contrary, increases. On the spark plug black.

Small the engine can be at idle and under load (in motion).

Causes of engine smoke

At the heart of all the reasons for the appearance of black smoke from is strong re-enricmentation fuel mixes Entering car engine cylinders. Based on this, it is necessary to establish the cause of such a strong re-enclosure.

Here are some options:

1. The float chamber of the carburetor works incorrectly. The so-called "overflow" fuel.

What could be the problem:

- the fuel level above the norm;

5. Extra fuel in the carburetor through the system idle move.

Accompanied by increased engine idle speed. You need to turn special attention For the purity of air gibber SHS, as well as the presence and absence of damage to the fuel jets of the idle system.

You can clean the entire idling system entirely. This cleaner is described in articles, "Cleaning the idling system of the carburetor 2105, 2107 ozone."

Adjust idling speed.

6. The aperture of the fuel pump is damaged.

Gasoline returns to the oil. Burning in cylinders, this mixture gives smoky black and gray exhaust. Check and fix the fuel pump (gas station).

Black smoke from the exhaust pipe can appear from any car: gasoline or diesel, no matter. Moreover, with any fuel supply system: carburetor or injection. The appearance of black smoke speaks about the occurrence of small faults in the engine, and if they cannot be eliminated in time, they will grow into serious breakdowns and affect the operation of other systems. As a result - expensive repair.

Black smoke is usually accompanied by an increase in fuel consumption and unstable work Engine, it is difficult to start in the morning, especially in the cold time. And the more stronger to press the gas, the more intense is black smoke. So what are the causes?

Causes of malfunction

The first reason - Fuel supply system malfunction. To the combustion chamber of the engine is served too much a combustible mixture, which simply does not have time to burn, from which the exhaust acquires a thick black shade. Such an exhaust is much toxic than normal, because It does not cope with its task from the overaffect of smoke.
The second reason - Incorrect operation of the ignition system. The fuel is simply not set up in the combustion chamber and goes straight to the muffler. Such a situation is accompanied by unstable engine operation, speaking by simple language, it starts to told.

Gas engine

If the engine has a carburetor fuel supply system to get rid of black smoke, you need to clean the carburetor jets with compressed air. Often this procedure is sufficient. If after that the black smoke does not disappear, you will have to spend money on the repair - change the needle in the carburetor, adjust the level of gasoline in the fuel cell, etc.

If the engine has an injector fuel supply system, you need to clean fuel system. Crashing nozzles can not properly fuel the fuel, hence the engine jerk. Revolutions constantly jump, no stable work. In this case, you will need diagnosis and repair of the nozzle. On the site defors.ru you can consult specialists.

Injector is an automated fuel supply system that works using sensors. If the fuel supply sensor is faulty, it will be supplied unnecessary fuel, it must be replaced. The last thing you need to do is check the health of the fuel pump. It should not create overpressure. Cleaning the fuel system can be made in several ways. The easiest - to pour a special additive in fuel tank.

Diesel engine

In itself, diesel fuel differs from gasoline. Even in good condition, the engine will have a black shade of exhaust. If the color intensity is noticeably higher, most likely clogged dairy filterand need it to replace or cleaning (regeneration). The procedure for cleaning the particulate filter is made in any car service. The second reason may be the failure of the pump high pressure.

Effects

the emergence of more serious faults. Over time, the catalyst will die completely, and it will be necessary to replace it, and it is not cheap. You can, of course, ride and without it, but the inspection will not work.

If the oversuizigation of the fuel supply injector will be covered, it may occur - a fairly serious breakage, after which will have to make the engine overhaul. And further. W. diesel engines Fuel ignition is accompanied by greater pressure. The oversupply of fuel in the combustion chamber can cause the block break, and this is a heavy breakdown.

Conclusion

Black smoke from the exhaust pipe is only a warning signal about the appearance of small faults. It is not worth tightening with them, and it is better to eliminate right away, which then rolve the engine overhaul.

The color and intensity of the engine exhaust for an experienced motorist - as a patient's body temperature for a doctor. An experienced look for a couple of minutes to watch, listen and sniff, and you can diagnose. In most cases, the normal color of the exhaust from the silencer does not attract attention and, if suddenly, on the road, the cars overwhelming you will signal and shown on the silencer, it is worth stopping and evaluating the problem.

Auto with black exhaust from the silencer, to put it mildly, do not welcome on the road. Well, if there is enough patience to ignore the signals of motorists, but by the striped rod, it is hardly possible to drive with impunity.

The reasons for the black exhaust of the silencer are well known, but it is better to repeat:

• fuel tank is flooded with a minimum half diluted with diesel or straight-rich gasoline;
• fuel apparatus and diesel filter diesel engine are in the dying stage;
• non-religious overflows the primary chamber or XX carb system, the preparation system of the fuel-air mixture cannot stabilize the composition in accordance with the optimal parameters.

Important! The presence of a black exhaust in a diesel engine may still mean that the driver burns out a scored sump filter exhaust system A slightly non-original way, for example, instead of using special additives into fuel, the engine is reconfigured to work on the depleted mixture under the intensive load.

Why appears soot and black exhaust from the gasoline engine silencer

The fuel combustion parameters in the chamber are calculated on a certain chemical and physical composition of the fuel. It is known that gasoline of good quality consists of more than ten diverse hydrocarbons, from paraffins to aromatic and unshakable compounds, with different molecular weight, temperature and combustion rate.

Light fuel components are well mixed and quickly burned. Heavyly burn slowly, they need a very high combustion temperature. In high-quality fuel, parity is approximately observed - in the production of light, medium and heavy components, a certain amount is added, based on the main guests on gasoline.

In self-made mixture gasoline prepared by simply merging of a small amount of light gasoline, methyltretile ether and fuel oil, there are only very light components and very heavy. Intermediate averages are always expensive, so they save them, and in the sub-cooked fuel they are quite rare.

In the carburetor or in the injector fuel rapp, thanks to special additives, light and heavy components are practically not resolve, and in equal amounts fall into the combustion chamber.

If the gasoline engine is warmed enough, the following happens:

• light volatile components are burning relatively quickly and in full even "on the cold";
• heat from light gasoline is not enough for normal evaporation and burning heavy components, there are no medium-sized gasolines, which means that there is nothing to support burning. All heavy kerosene-fuel oil is partially disintegrating with the separation of the diesel particles.
• the final decay of heavy residues occurs in the collector and exhaust tube with black exhaust.

The operation of the engine, which has a black exhaust from the muffler, unstable and with obvious passes of flashes in separate cylinders.

In addition to poor-quality fuels, the cause of black exhaust from the muffler can serve as dirt and resin, creating resin and paraffin plugs in pipelines and injectors. Often they clog the nozzle, preventing it in normal operation. With overpressure or flushes a plug, or squeezes into a combustion chamber with a huge amount of excess fuel, which leads to a black exhaust from the muffler. Best way eliminate exhaust with black fuel residues is replacement fuel filters And flushing pipes.

Black exhaust - result of incredited fuel equipment

Diesel engines turned out to be more susceptible to plantation. Approximately similar processes giving black diesel emissions and exhaust, occur at the time of spraying. diesel fuel Either with delay, or with explicitly excessive solarium.

Tip! Often, prophylactic adjustments give a certain effect of reducing the black exhaust from the muffler, but after a while the black cloud reappears on the muffler cut. In this case, the main perpetrators of the appearance of the exhaust with soot are the tips, nozzles sprayers, the diameter of which is explicitly increased due to the operating fuel with a high content of abrasive.

Often the effect of black exhaust from the diesel muffler can manifest itself to a short period and also suddenly disappear. In this case, check the work oxygen sensor and controller ECU.

Realification of the mixture and black exhaust

Work on a re-engaged air and gasoline mixture causes intensive overheating of the motor, which in itself gives dark and sIZY smoke From the muffler. For high temperatures The viscosity of the oil is so falling that it easily penetrates the combustion chamber and adds small portions of engine oil to an excessive amount of fuel. So the black exhaust of the muffler appears with a black liquid dripping.

If the engine is worn out so much that the lubrication easily penetrates through masonry rings and seals on the valves, get rid of black exhaust possible only overhaul With the replacement of rings and seals.

For the carburetor version, re-enclosure occurs due to improper adjustment of the idling system of XX.

With increasing motor revolutions, the bypass channels of the XX system are not turned off, and continue to fill the intake manifold excess gasoline. You can check the assumption about the causes of the black exhaust, by installing a worker and adjusted carburetor on the problem engine. In most cases, the hosts of the car prefer not to "treat" a sick knot, and replace new.

Why the exhaust pipe goes black smoke and drips fluid and how to avoid it is shown in the video:

Almost every car immediately after starting the engine is noticeable from the muffler. Normally, they are pairs, the transparency of which depends on the temperature of the motor - the hot engine, the more transparent steam. Couples should become unnoticed after the warming of the car, and if this does not happen, it means that something is wrong with the machine. In the article, we will tell about what faults can evidence different color of the exhaust.

1 because of what exhaust gases acquire a characteristic color?

Selection from the muffler may have different shades. White smoke from the exhaust pipe, as well as gray and black are most often found. It is in color that indicates the nature of physical and chemical processes occurring in the engine, you can determine which problems your car has. Characteristic shades of smoke indicate a malfunction of the mechanism of the gas distribution, cylindrical group, power system, injection control, cooling or ignition systems.

Different processes can paint smoke, namely:

1. Incomplete or low-quality fuel combustion can paint smoke in blue or black.
2. Antifreeze in the combustion chamber makes smoke white.
3. The combustion of the oil in the cylinder stains pairs from the pipe in blue color.

However, it is not always possible to accurately determine the malfunction of the machine only by the color of exhaust. There are no cases when a malfunction in the system, leading to staining of smoke from the pipe, is a consequence of problems in other vehicle systems.

2 White smoke or white couple - What does the car malfunction?

Most often, in the detection of white steam from the exhaust pipe, car owners think about the problems in the engine. Couples are best noticeable during the warm-up of the motor, but it does not always indicate any faults. In the cold exhaust system, moisture accumulates, condensed from the air, and when heated it evaporates and becomes a ferry. As evaporation, the steam-coming from the pipe must disappear.

The saturation of the steam depends on the humidity - the higher the humidity of the air, the thick of the steam.

The color of the pair affects the air temperature:

• at -10 ° C pairs can form during the operation of the heated engine;
• at -20 ° C pairs can purchase a nine shade.

The so-called "white smoke" most often turns out to be a steam obtained as a result of condensate formation in the exhaust system

If, with a positive air temperature, the engine warmed up, but the white exhaust did not disappear, cooling fluid could get into the combustion chamber. The reason for this is damage to the head of the cylinder block or problem with the gasket of the GBC. When antifreeze in the camera, water, which is in its composition, does not have time to evaporate and turns into white pairs. It is when he looks like smoke.

A pair shade depends on the antifreeze used, air humidity, ambient temperature and illumination. Couples may look naiz and remind smoke characteristic of the combustible oil. Discern a couple and smoke is very simple, whatever the color of the couple, it is quickly dissipated, but the fog of a bluish shade remains in the air.

3 white smoke and faults that cause it

When a white pair is detected, similar to smoke, it is necessary to initially confirm the presence or absence of a cooling fault. To do this, you will need a sheet of paper that you need to apply for 15-20 seconds to the silencer hole when the engine is heated. If the oil is burning, then noticeable oil trails will remain on the sheet.

Next you need to check for damage to the cylinder and cylinder block. Damage to the cylinders during the operation of the engine leads to the fall in the exhaust cooling system. Therefore, to determine the problem, you must open the radiator cork. If you see on the surface of antifreeze (it will be less than the usual) oil film or feel the resistant smell exhaust gases - The problem is really in the cylinder block.

It is recommended to check the oil for the formation of emulsion. Open the oil pouring cork or pull the oil dipstick. When passing through the engine channels, the emulsion leaves a consecable foam on a stopper or lid, the color of which can range from yellow-brown to light blue. Emulsion in oil appears due to antifreeze in the cylinder. Over time, it passes through the piston rings, and then it turns out in the oil and in the pallet of the crankcase. Due to mixing with antifreeze, oil becomes emulsion and brighten.

Minor cylinder defects, leading to a small amount of antifreeze into oil, may not lead to the formation of the emulsion, but the foam on the traffic jam will appear. Strong wells and cracks lead to the accumulation of antifreeze above the piston, which prevents the crankshaft starter at the first moment when the engine starts. All this can cause a hydroedar in a cylinder, breakdown piston rings, pistons and valves.

Next, you should check the state of the spark plugs. To do this, it is necessary to initially turn the crankshaft to the position in which the valves will be closed, turn on the transmission and keep the car on the brake. In such conditions, it is necessary to pull the candles alternately and carefully inspect them. If antifreeze hit the system, it can clean the candle, make it outwardly similar to the new one. If one candle is clean, then you have found a breakdown, you can confirm this by sending air under pressure to the cylinder, because of this, the fluid in the tank will increase.

It is recommended to check the possibility of antifreeze to the cylinders through the inlet system. This is possible if the intake manifold laying has severe damage. There is also damage to the sealing unit throttle valve. Most often, such problems are found in Asian cars. In such conditions, the pressure in cooling is not increased, there is no smell of exhaust and there are no signs of converting oil into the emulsion, but in the exhaust there is a strong smell of antifreeze, accompanied by an active career.

The next stage of diagnostics is the removal of the GBC and the mechanical test of the motor. You need to check the condition gBC padsAnd also inspect the combustion chamber, the bottom of the piston and the valve plates. The start of the gasket of the GBC can occur due to overheating of the motor, which is often accompanied by deformation of the head of the cylinder block. If the problem is confirmed, you will need to poll the plane of the GBC and replace the gasket. If, when removing the head of explicit defects, it is not noticed, you will need to check the head for tightness - perform crimping under pressure. You also need to check the cylinder itself for integrity. To do this, it must be omitted in bottom point And inspect.

Thus, there are a number of reasons, because of which white smoke can go from the muffler. It is very important to find the root cause of the detected smoke, and it is not recommended to ride a damaged car. When the oil turns into the emulsion, the load on the engine parts is sharply increasing, which can lead to even more significant malfunctions. Cracks in cylinders can quickly progress. If when a problem is detected, immediately contact the car service, the repair can be limited to the replacement of the GBC laying, but if you continue the operation of the machine with damage and on bad oil, you can drive to overhaul.

4 Why is the silencer goes black smoke?

Unlike white smoke, which can be confused with steam, black is really smoke, which acquires its color due to particles contained in it, appearing in case of incomplete combustion of the fuel mixture. Black smoke always indicates an unnecessary enrichment of the fuel and air mixture, based on what can be concluded about the presence of problems in the ignition system, nutrition or injection control. Such breakdowns are always accompanied by increased fuel consumption, unstable operation of the motor, poor engine launch, high contaminance of exhaust gases and the total power loss of the car. That is, the damaged car simply does not pull.

In the car with a carburetor, smoke appears due to the wrong angle of the ignition and malfunction of the carburetor itself. Fuel can be blocked into the float chamber due to the breakdown of the needle valve or due to the contamination of air jaws by burnt oil.

Black smoke may appear when malfunctions gasoline engine. If the fuel supply is performed through an injector controlled by a computer, re-enrolling the fuel mixture is possible due to the fault of the flow meter or lambda probe. In addition, the problem may occur because of the injectors flowing. The main danger of the described faults is to get into the cylinder of gasoline, due to which the piston will not be able to reach a dead point, as a result of which the likelihood of the hydroudar appears.

Diesels black smoke can act a malfunction fuel equipment. This is possible not only because of the defects of the high pressure pump, but also due to the large angle of the injection. For a diesel engine, as for any other, it is harmful to function on a too enriched mixture. Because of this, an increased wear of the engine elements is possible, the appearance of scaling on the walls of cylinders, where the fuel will wash off the oil, worsening the lubricant of parts.

Unburned fuel can burn in a catalyst that will be late, because of what a fire may appear, which threatens not only the car, but also its owner. To detect such a problem, it is enough to remove the oil probe, while the oil level will be enhanced, and the resistant smell of fuel will go from it.

5 Blue Oil Smoke - Causes and Possible Consequences

The main reason for the appearance of a blue shade smoke is the combustion of oil in the motor. Blue smoke is called oil, it testifies to the problems with the engine. Depending on the type of malfunction, the color and texture of smoke may vary. It can have a blue shade or be saturated blue.

The color of the smoke during the combustion of the oil may vary and depends on a number of factors, starting with the degree of engine heating and the number of revolutions and ending with the amount of oil, oil makeup and external environmental conditions. Oil smoke is easily distinguished from steam, it holds for a long time in the air and has a characteristic smell.

By the nature of the smoke, you can determine the degree of wear of the car engine:

1. Smoke blue-white or blue is well noticeable only when the cold engine is started, and it becomes smaller after the warming up. Most often, this indicates the lack of substantially worn items. It is explained by the expansion of individual elements when warming up.
2. Smoke is best noticeable on a warm engine. Indicates a strong wear of the engine elements. The extension of the parts is not enough to seal the leakage, the oil easily flows into the cylinder. Such an engine consumes oil in large quantities.

Diagnosing the causes of smoke, it is necessary to remember that compression can be both overestimated and understated. Compression can be reduced, since the details of the cylindrophone group were strongly worn out, and the pressure of crankcase gases increased. But due to the large volume of oil falling into the cylinders, there is a sealing of the gaps of adjacent parts. If the gaps are not very high, then compression measurements can give normal or slightly overpriced results.

There are two ways in which the oil can fall into the combustion chamber:

1. Through the gaps between the guide sleeves and the valve rods.
2. Through piston rings.

If in your car heavily smokes the engine, produces white, black or blue smoke, it is strongly recommended to use it. Trips on a damaged car will not only completely uncomfortable for you, but also truly destructive for the car itself. The problems with the car and breakage only will be exacerbated, which will lead to a sharp increase in value repair required. Follow the state of the car and, without losing time, give it to the car service when smoke from the muffler appears.

Large white cloud of smoke

Running car with cold winter in the morning, you have repeatedly noticed the clubs of white smoke coming out of the exhaust pipes, enveloping the car from behind. Cloud rises up and completely dissolved in the air. The formation of such "smoke" is explained by the fact that the engine of the car cools overnight and becomes very cold. The cloud in its composition is not smoke, it is water vapor, which is condensed under the influence of cold air. Water steam is a by-product of gasoline combustion and formed at cold temperatures. What it is lower, the more and more noticeable cloud. A large amount of water vapor in the exhaust indicates good engine operation. For the exhaust system itself, his education is not a good indicator. With long trips when the engine is heating to optimal operating temperatureWater evaporates completely. If the car moves to short distances, the engine to the desired temperature is not heated, and the water remains in the exhaust pipes and the silencer, which causes corrosion.

Blue-white smoke

If the launch of the car is accompanied by the release of bluish smoke from exhaust pipes, this suggests that a small amount fell into cylinders. When the engine is started in a few seconds, oil combustion occurs, the smoke disappears and no longer appears. The appearance of bluish-white smoke does not speak of a serious problem, does not exceed the oil consumption and is not a sign of wear of the pistons. It can be compared with the "obedientness" of the body in the morning, which quickly disappears after several movements.

The formation of thick white smoke after heating

The appearance of white smoke after the engine warming when its cloud reaches huge sizes and density, talks about an existing problem. The thick white smoke is a sign that the coolant, half consisting of water, got into the engine. When the engine is heated, the metallic parts are expanded, of which it consists. Between items, including in cylinder heads, laying gaskets, called seals. Their task is not to give a flow of coolant inside the cylinder. When wearing the glands of the heads, the liquid begins to leak into the cylinder. In order to avoid serious problems with the engine, the cylinder block gaskets are required. Thick white smoke may also appear as a result of cracking in the cylinder head. This is a serious problem that requires access to the car service.

Permanent white smoke

Some cars of the mid-90s are equipped with a valve with a vacuum engine hose. The formation of thick white smoke occurs due to hitting transmission fluid In the engine through this valve. The liquid falling into the cylinders quickly pollutes the spark plugs, which entails the absence of the spark and the inoperability of the cylinder. There is nothing good in this, but it's not worth talking about the big risk for the engine in this case.

Education of black smoke from the exhaust pipe

Black smoke, which comes from the exhaust pipe, testifies to the wrong fuel in it. Smoke may appear as a result of a large amount of fuel in the cylinders due to the bay of candles. On the modern cars With the injectors of the bay of candles can occur due to the pressure of the fuel or injection system. There may be other reasons. For example, power loss and. At a certain point, the candle is finally polluted and stop working. To correct this problem need special equipmentAvailable in car service.

Permanent blue smoke

If a motor oil Constantly falls into the cylinders, there is a constant presence of bluish-white smoke. It's connected with piston Ringsealing the gap between the piston and the cylinder. Attentive to his car, the motorist will notice the increase in oil consumption characteristic with this problem and will be able to solve the problem in time. If you leave it without attention, the oil can pour candles and problems will become more. To check each cylinder, special equipment will be required, that is, you will have to contact the car service.

9 comments on "go smoke from the exhaust pipe - gray, blue, white, black smoke from the exhaust pipe"

A very useful article, definitely in bookmarks, it is especially worth paying attention to the exhaust when you get a car. If there is smoke, then bypass the car.

It is difficult to determine the condition of the engine in the color of the smoke. My friend Moskvich passed more than 100 thousand. Frankly, still unknown, as he smokes. In the morning cold Engine - The pair can be seen with the naked eye, the garage closed and drove. Do not warm the engine never. Rings are not touchdown, butter does not take. But the chemotes we regularly. Any serious additives - tried. Determination of serious intuition. Fuel consumption, which was new car, the same remained. From mechanical instruments IS IS for adjusting the carburetor.

The entire visual diagnostics of the condition of the car in the color of smoke from the exhaust pipe is excellent. Let it be no one hundred percent hit, but still a hint of "diagnosis" real. And using this can be warned by the "disease", conducting preventive check and the necessary adjustment.

Not always, pair of exhaust pipe should be ignored if it can somehow explain it in the cold, then when it is warm and appears such a pair, then this indicates the leaks of the coolant to the cylinders, and, therefore, it will be necessary to check the piston cuffs and rings that are not Support the tightness of the block. And also the formation of black smoke can not talk about any serious malfunctions, but only a bad fuel, especially often it is noticeable by diesel cars.

In addition, you need to know that domestic cars "Drink oil", i.e. It is elementary enters the fuel system and it is considered the norm, but there is no such thing on modern foreign cars, there will be how much oil will flood the same thing in a year. Therefore, the presence of oil in the motor and, accordingly, a bluish-white smoke, which comes from the pipe, does not indicate a malfunction for domestic machines. I'm not talking about the color of smoke when bayed in a typewriter of the hard oil, which is of such a burner color, which I think with him even salon Auto There will be a special smoke.

Alexey, I do not believe that the Vazovskaya Troika may not eat oil. In order to reduce oil consumption, you need to minimize the engine of the engine, change all the rings, piston, laying the cylinder block and then fully remove its consumption. I think I do not work out. And measure the amount of oil during its minimum consumption can only be drained completely old from the system, flushing it and only then pour a new one, and after half a year, as you say, again merge the oil and see its quantity, but only know what is still in The system will remain its some part, so the statement that allegedly "neither the oil droplets for half a year did not go" does not correspond to reality, or you have some kind of high-quality measurement method. How did you measure? By oil Shchu You definitely do not define if it decreased by 50 grams. Perhaps you simply did not correctly calculate the number when the new oil was poured, did not take into account that there was also a certain amount of old in the system, and in the end it turned out zero consumption.

The article warns, and gives elementary concepts how to determine the malfunction. But judging by the reviews all the super specials, and the VAZ oil can not not "eat" and a foreign car is a limit of perfection - read the instructions for your foreign cars and theory of DVS. Then stop clever and write nonsense. Thanks to all.

Information is useful but not fully described. There is such a thing as a car does not smoke, but sometimes smokes a bluish shade with a culprit in such a situation there are worn out valves oil seals. It happens when the car slows down the engine, at this time the ignition does not occur, the oil is going in the cylinders and, if necessary, the driver presses the gas pedal on the gas pedal goes short-term combustion of the fuel oil and we see the cloud of blue smoke, then it all disappears and the car works in normal mode. Or smoke may appear from overpressure in the engine with which the milk oil seals are not able to cope occurs this most often on the protracted lines.

The article is cognitive and useful. I can tell how to get rid of the white cloud of smoke, which appears due to water in the silencer. Everything can be done in garage conditions Within ten minutes.

You will need:
1. Drill
2. Drill with a diameter of 3mm.

It is necessary to visually mark the lowest point of your silencer and drill a hole there. Through this hole, the whole moisture will flow, which used to be collected in the silencer and created a large white cloud of smoke. Thanks to this hole, you not only get rid of smoke, but also extend the service life of the muffler twice. Inside the silencer will be constantly dry - therefore, corrosion will not develop.

By the way, earlier, the domestic auto industry did these technological holes in production. Then they stopped and began to make money well on selling new silencers. I drive the sixth year daily on one silencer with a hole. The silencer without a hole was enough for two years a maximum. And the last, the hole does not affect the sound of the exhaust.
