What is the problem of the car exhaust pipe spraying gasoline and white smoke

White smoke from cars is common in winter, as the white smoke we see is basically water vapor. There are two scenarios here:

Normal. The water vapor produced after gasoline combustion is normally discharged through the exhaust pipe, and due to the relatively low ambient temperature, the water vapor will condense and converge into small water droplets, which will change into water vapor that can be seen by the naked eye.

2.There is a fault. As part of the coolant enters the cylinder, it will appear as water vapor as the exhaust gas is discharged due to the high temperature.

In most cases, the white smoke emitted from gasoline injection from the exhaust pipe of the car is caused by the incomplete and insufficient combustion of the fuel mixture.

1. One possibility is that the mixture is too thick.

2. It is also possible that the ignition quality is too weak due to the poor working condition of the engine ignition system.

3. If the cooling water of the water tank is reduced: it means that the engine cooling channel or cylinder gasket is damaged, resulting in the cooling water entering the cylinder for combustion.

4. There is no shortage of cooling water: caused by water entering the exhaust pipe for some reason (rain or car washing).

5. White smoke from the exhaust pipe is absolutely abnormal. It is best to detect the cause, otherwise the exhaust pipe will cause corrosion to the exhaust pipe for a long time, and the exhaust pipe will be rusted and damaged in advance.

Normally, if the ambient temperature is relatively low, then the exhaust gas discharged from the engine may condense into small water droplets after being cold, which seems to us to be white water vapor, as long as it is not a particularly large amount of water vapor, we generally do not have to worry, this phenomenon is especially common in winter.

First of all, let me explain that the white smoke is the genuine factory [cold weather is more obvious] gasoline is definitely not [because the temperature of the exhaust pipe exceeds the ignition point of gasoline I don't know how many times, if the gasoline can't get here, it will burn out].

What you are talking about should be the smell of raw oil [it should be the substance emitted by incomplete combustion of gasoline] Analysis: The engine is not working very well Since the fault indicator light is on, you had better go to the auto repair shop computer to decode I estimate that it may be these sensors.

1: Three-way catalysis.

2: Absolute pressure sensor.

3: Throttle position sensor.

4: Crankshaft position sensor.

5: Inlet air temperature sensor.

The first four are the most likely

There is also a fuel injector leakage that cannot be detected by the computer version, if these are good, it is recommended to check the high-pressure package, spark plug and the inside of the engine.

The improvement of the national economy has also led to the improvement of consumption capacity. The most striking manifestation of our country is that basically every house has its own car. However, many car owners' understanding of cars has been in a very low state.

Many of the working conditions of a car can be representative of what the car is actually like.

Car owners don't recognize the seats, which can exacerbate the severity of the car problem. At that time, it was a big expense to be taken to a car repair shop. For example, when a car smokes white cigarettes.

There is a reason for the white smoke emitted by the car, a very serious reason, if it is found, it should be checked in time, when the outside temperature is low.

At this time, it is usually winter, the outside temperature is low, and the car engine will produce carbon dioxide, water and other emissions when burning fuel, and it will be in a high state when it is discharged to the outside of the car, so when the outside temperature is low, the physical change of liquefaction will occur, so the appearance is that the car emits white smoke. It's a simple physical phenomenon and it's normal.

Engine sealing issues. If there is a large amount of white smoke in the car, and this phenomenon does not decrease in the slightest, there will be problems with the engine seal, causing water to flow into other liquids such as water. If water flows into the cylinder, it will turn into water vapor and produce large white smoke when exhausting, so a simple analysis of the engine to check whether the tightness is complete is more involved.

Fuel** system issues. Generally, when a car discharges a large number of white machines, in fact, the part with a slightly simpler structure is checked first, and the structure of the refueling system will be much simpler than that of the engine, and this part of the inspection items is also relatively simple. One is to make sure there are no other things that are going into the engine cylinder together when refueling.

Ask a good question. Answer: White smoke comes from the exhaust pipe, and there is water, in this case, it means that you need to check the antifreeze, look at the antifreeze, if there is no shortage, it is caused by the poor combustion of the engine. You only need to clean the throttle and fuel injector, replace the spark plug, clean the three-way catalytic converter, and check the atomization effect of the fuel injector.

Is there a nuisance? To answer this situation, just check that the antifreeze is not missing, clean the carbon deposits of the engine, replace the spark plugs, and check the atomization effect made by this friend.

Ask how much it will cost.

is normal. After gasoline is burned, the water vapor is discharged normally through the exhaust pipe. Because of the low ambient temperature outside, the water vapor condenses into small water droplets, which become visible to the naked eye, emitting white smoke.

It's a glitch. Some of the coolant enters the cylinder, so the exhaust gas is discharged at a high temperature when the exhaust gas is discharged, so water vapor is ejected.

Generally normal, but if the owner is not at ease. You can go to the repair shop to check it. The complete combustion of automobile gasoline produces carbon dioxide and water, and the water turns into water vapor at high temperatures, which is colorless and transparent at high temperatures.

At low temperatures, the water vapor condenses into water, and the condensed water droplets are small and float in the air, and white gas is discharged. The production of white smoke in the exhaust of the car can be solved by cleaning or replacing the injectors, adjusting the spray pressure.

Remove water from the fuel tank and oil ducts. Don't buy low-quality oil at a low price. Replace cylinder head gaskets, cylinder liners, cylinder heads.

The treatment method of white smoke emitted from the exhaust pipe of the car, if the car has the phenomenon of white smoke emitting from the exhaust pipe. It could be a stain on the vehicle's air filter, insufficient air intake, a malfunctioning carburetor, or a contaminated oxygen sensor inside the exhaust pipe, which could be because the computer is not able to provide accurate information for the placement. Normal white smoke is caused by exhaust gas emissions from the exhaust pipe, and when the temperature of this exhaust gas reaches a certain level, water droplets condense.

If a large amount of white smoke occurs, the engine piston will be damaged, and if the engine oil is burned, a dull white exhaust will be produced, or the gasoline will contain too much water. In addition, the gasket in the waterway may be the result of a breakage. The high temperature in the cylinder is also the gas flowing into the user's housing, and the oil often deteriorates, so it should not be too much or too little oil when adding it.

Generally speaking, the exhaust gas is just water vapor, but there are also cases where water vapor produces white smoke due to the influence of the idle speed of herbal tea. In fact, the phenomenon of white smoke is relatively easy. Unless black smoke or blue smoke appears.

The question burned the engine oil, white smoke, and it stinks.

Question: Do you use a folding engine?

What is the reason for this?

It is water vapor that is emitted from the exhaust pipe. Because the water and carbon dioxide produced after the complete combustion of gasoline form water vapor at high temperatures, and condense into water, the water droplets are smaller, and the water droplets will become white gas when suspended in the air, and the condensed water droplets will accumulate and become water.

It is likely that there is too much water in the gasoline, which cannot be burned, so it is naturally discharged from the exhaust pipe.

If you find white smoke during driving, it may be because there is less water in the water tank, or it may be that the tank mattress is leaking, so it will emit white smoke.

It may be because there is a lot of water vapor, or it may be because the car has a particularly serious failure problem, so at this time, it must be checked and repaired in time.

This phenomenon means that the cooling of your car's water tank has been reduced a lot, causing the cooling water to enter the cylinder for combustion, so this white smoke will be discharged.

Mainly because the fuel is not fully burned from the exhaust pipe, forming milky white smoke, it is more common in winter, and the low temperature causes poor fuel atomization, which generally disappears after starting the hot car and the temperature rises.

This is because gasoline contains moisture and the engine is too cold, when the fuel entering the cylinder is not completely combusted, resulting in fog spots or water vapor to form white smoke. In winter or during the rainy season, when the car is first started, white smoke can often be seen. It doesn't matter, as soon as the engine temperature rises, the white smoke disappears.

This condition does not need to be serviced. Such as satisfied.

As can be seen from the headlight structure, whether it is halogen headlights, xenon headlights or LED headlights, the inside of the headlights is almost sealed with sealing strips. When removing the back cover of the headlight, you will find that there is a layer of sealing strip on the headlight, which is the main measure to prevent water from entering the inside of the headlight of the car. In addition to this, there is a vent in the headlamp for ventilation inside the headlight, but there is also a dry cotton-like treatment at the vent to filter the air entering the headlight.

From the above two measures, it is not difficult to see the real reason for the fogging inside the headlights. The first point is that the headlight back cover seal is damaged when it ages after long-term use or when disassembled. The second point is whether the dry cotton of the vents is still intact.

When a car headlight is turned on, a lot of heat is generated, the air inside the headlight expands, and the air is exhausted through the headlight outlet. When the headlights stop working, the internal air cooling needs to be supplemented by outside air. At this time, the drying cotton of the air outlet plays a drying role, which can filter out the moisture in the air and ensure that the inside of the headlight is dry.

However, in general, although water will enter the headlights, it will not collect in the headlights to form such a large fog, and the heat emitted is enough to expel moisture from the car without driving. The reason may be that the rear of the headlight is not tightly sealed and aging. If, likewise, after the headlights are turned off, moist air enters through the back cover instead of the vents, it turns out that after driving for a while, water mist is found inside the headlights, which is also related to the season and the temperature difference between day and night.

The treatment of fog and water droplets in the headlights of the car is divided into two situations: turn on the headlights when there are fewer fog and water droplets in the headlights, and disassemble and dry them when the fog and water droplets in the car headlights are more.

Here's how:

1. There are fewer fog and water droplets in the headlights: the fog and water in the headlights can be turned on by turning on the headlights, and the heat generated by the headlights within 15 minutes can evaporate the fog or be discharged through the exhaust rubber pipe with the heat wave, which generally will not cause damage to the headlight circuit or bulb.

2. There are many fog and water droplets in the headlights: in this case, it can be judged that there is a problem with the sealing of the headlights, such as the damage of the headlight cover or the back cover, or the sealing strip between the lamp cover and the back cover. At this time, the owner will not be allowed to continue to use the vehicle, go to the repair shop to ask the professional staff to remove the headlight assembly of the vehicle, and wipe the water mist inside the headlight.

Then replace the sealing strip of the headlight assembly to avoid long-term use, resulting in water ingress inside the headlight assembly, damage to the connection line of the headlight of the vehicle, and even damage to other parts of the vehicle.

This is because the resulting exhaust gas has liquefied, which is normal and there is no need to make a fuss.

It is likely that the vaporization of the fuel is not particularly good, so the emitted gas becomes milky white, or it may be because the temperature is relatively low, or it may be because the atomization situation is not particularly good.

It could be because of a clogged exhaust pipe, or it could be because the engine burns oil very badly.

Mainly because the weather is very cold, and there are some other substances in the car, so it can only be discharged in this way.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

If the engine exhaust pipe emits white smoke, you need to check the antifreeze to see if there is a lack of antifreeze, if the antifreeze is missing, it means that the cylinder gasket of the engine is rushed, and the engine is boiling water.

Question: There is no shortage of antifreeze, the car can be driven normally, but the smoke is very large.

It should be burning engine oil, such a phenomenon must be paid attention to, and it must be repaired and inspected as soon as possible.

Some car owners are very confused by the white smoke coming out of the exhaust pipe of their car. What's going on with the white smoke coming out of a car's exhaust pipe? What to do if white smoke comes out of a car exhaust pipe?

Let me tell you about it! What to do if white smoke comes out of a car exhaust pipe? If you look closely at the white smoke of the car, it is not difficult to see that the white smoke actually emits a large amount of white water vapor, which is accompanied by the engine running.

What to do if white smoke comes out of a car exhaust pipe?

If you look closely at the car emitting white smoke, it is not difficult to find that the white smoke actually emits a large amount of white water vapor, which is accompanied by the phenomenon of unstable engine operation, and even after the engine is warmed up to the normal working water temperature, it will still emit a large amount of water vapor.

The reason for the above situation is most likely due to the wear of the cylinder gasket of the engine cylinder, which creates a certain gap, which causes a large amount of moisture in the heat dissipation system to enter the combustion chamber through the gap. When the non-combustible water is heated, it produces steam that is discharged directly from the exhaust pipe.

In addition, some cars emit white smoke because they encounter the legendary "black-hearted gas station", and the product after refueling is mixed with water by unscrupulous merchants, but this situation usually starts to emit white smoke after a certain refueling, and it is relatively easy to find the reason.

If there is white smoke in your car, you should check the engine block and head gasket for damage as soon as possible, and check the fuel tank for water. If you've just bought a new car, be sure to check the instructions carefully and add the right labeled gasoline exactly as the manufacturer prescribes.

Is there a problem with white smoke coming out of the exhaust pipe of a car.

The white smoke emitted by the car is likely to come from the following aspects: dirty air filters and insufficient air intake; The vaporizer is broken. EFI trucks without carburetors can also be contaminated with the oxygen sensor in the exhaust pipe and fail to provide correct information to the valve computer.

Normal white smoke is caused by the high temperature of the exhaust gas coming out of the exhaust pipe, and if there is a large amount of it, it will condense the water vapor into small water droplets. It could be that one of the engine's pistons is broken and the oil starts burning. The strong white color in the exhaust gas is naturally due to the high water content in the exhaust gas.

The reasons are none other than the following:

1.Too much water in gasoline.

2.The waterway gasket is damaged, the cylinder liner is damaged, and the cooling water enters the cylinder.

The high-temperature gas in the cylinder rushes into the oil pan, causing the oil to deteriorate, pollute and dilute, and affect the lubrication effect. The harm is obvious. So when refueling, be sure to add the right amount as needed.

White vapor is usually water vapor. The reason why you spray a lot may be that the idle speed of the cold car is high, so there is more gasoline naturally burned, and there is more water vapor coming out, which is related to the thickness of the car's exhaust and the size of the three-way catalytic network. Although his car has just started to turn on, it doesn't have to be cold, so don't worry, as long as it doesn't emit black, blue, or yellow smoke, it's fine.

The injection angle is small, and the combustion is incomplete; Slight leakage of cylinder liners, water in the fuel; However, white smoke will appear during cold starts, especially when the engine is started at low temperatures, but it is normal for white smoke to disappear as the engine temperature increases.
