What happens to the white smoke coming out of my car s exhaust pipe?

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.

The main reason for this situation is that the fuel is not completely burned, which is generally more common in winter, because the low temperature causes poor atomization of the fuel, and the temperature rise will disappear after starting the hot car.

The white smoke from the exhaust pipe of the trolley is likely to be due to the wear of the cylinder gasket of the engine cylinder, which produces a certain gap, causing a large amount of water from the heat dissipation system to enter the combustion chamber through the gap. Water that cannot be burned is heated to produce water vapor that is discharged directly from the exhaust pipe. If the car has already emitted white smoke, it is necessary to check the engine block as soon as possible.

It is normal for the exhaust pipe of the car to emit white smoke, which should be gasoline containing ethanol, and the ethanol is in a state of water vapor after combustion, so there will be white smoke!

White smoke from the exhaust pipe is the water vapor that is emitted from the exhaust pipe.

If the cooling water in the tank is reduced, it means that the engine cooling channel or cylinder gasket is damaged, causing the cooling water to enter the cylinder for combustion.

There is no shortage of cooling water: for some reason (rain or car washing) causing water to enter the exhaust pipe.

White smoke coming from the exhaust pipe, 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.

This is because the substances in the gasoline additives are burned to produce water, water vapor at high temperatures.

White smoke is not a big problem, and it is only for a short time, and the reason is very simple: the water is heavier than the oil, you stop for four days, and the oil pump is at the bottom of the tank, sending the water to the water vapor produced by the combustion of the engine. Two:

Water vapor produced by heating the water from the exhaust pipe due to the high temperature of combustion. Three: It's a little scary, that is, the water vapor generated by the coolant entering the combustion chamber.

The main reason.

The reasons for the white smoke emitted from the exhaust pipe are: 1. The cooling water of the water tank is reduced and excavated; 2. The engine cooling water channel or cylinder gasket is damaged and the cooling water enters the cylinder for combustion; 3. It is best to detect the original digging bucket, otherwise the exhaust pipe will corrode the exhaust pipe due to water vapor coming out for a long time; 4. The exhaust pipe is corroded and damaged in advance. When a cold car is first driven in winter, a large amount of white smoke comes out of the rear exhaust pipe of the car's engine.

However, after driving for a period of time, as the temperature of the car engine increases, the white smoke gradually subsides and returns to normal, indicating that the temperature of the car engine is too low to be eliminated. Place your hand near the exhaust pipe. When white smoke blows through your hands and there is a mist of water, it means that the water has entered the tank.

At this time, you can find the leaking cylinder by cutting off the oil in the single cylinder. If the speed of the diesel fiber dispersal machine is affected when the single cylinder is cut off, it means that the cylinder is working well; Otherwise, it means that the cylinder is not working, and the injector should be removed for inspection and repair.

White smoke comes out of the exhaust pipe of the car, and if it is white smoke under normal conditions, it is usually caused by the outside temperature being too low. Usually this situation is not left unattended, but if it is caused by other problems, then it is necessary to check carefully.

In addition to the above reasons, the faults that may also occur are as follows:

1. The air filter is dirty, in this case, there will be water or oil in the air intake type of the air filter, which will make the car exhaust white smoke. It can be improved by washing. If the cleaning method is not obvious, the filter can be replaced directly.

2. The cylinder gasket is damaged, the cylinder steel is cracked, and the sleeve sealing ring is defective. Go to a professional repair facility for inspection first, and then repair according to the specific problem. Replace in a timely manner if necessary.

3. If the amount of white smoke is particularly large, it is likely that the engine piston is broken, and a large amount of white smoke is produced by burning engine oil. The engine is broken and needs to be replaced at a professional repair shop.

4. If the owner does not replace the coolant for a long time, and the quality of the coolant used by the owner for a long time is not good, then the cooling effect of the car will not be good. Therefore, car owners should change the coolant in time. As a general rule, change the coolant every two years, and also choose a regular brand to prevent other situations.

5. Under normal circumstances, if white smoke appears when the car is started cold, then with the continuous increase of engine temperature, the white smoke disappears as a normal phenomenon. For example, when the temperature is low in winter, white smoke coming out of the exhaust pipe is a common phenomenon. However, if there is still a large amount of white smoke at room temperature, it is best to check and repair it as soon as possible.
