What’s the matter with white smoke coming out of the exhaust pipe? What should I do if there’s white smoke coming out of the car’s exhaust?
What should I do if there’s white smoke coming out of the exhaust?
Method/Steps
1. The problems with your car are also likely to be caused by the following aspects: the air filter is dirty and the air intake is insufficient; the carburetor is faulty. EFI cars without carburetors , it may also be that the oxygen sensor in the exhaust pipe is contaminated and cannot provide correct information to the gas distribution computer.
2. Normal white smoke is caused by the high temperature of the exhaust gas coming out of the exhaust pipe, which condenses water vapor into small water droplets, if there is a large amount. It may be that one of the piston in the engine is broken and it starts to burn oil. The thick white color in the exhaust gas is naturally due to the high water content in the exhaust gas. The reasons are nothing more than the following two: too much moisture in the gasoline; or the sealing gasket of the water channel is damaged, the cylinder liner is damaged, and the cooling water enters the cylinder.
3. The high-temperature gas in the cylinder escapes into the oil pan, causing the oil to deteriorate, contaminate, and become thinner, affecting the lubrication effect. The harm is obvious. Therefore, when adding engine oil, you must add the appropriate amount as required.
4. White steam is generally water vapor. The reason why you spray a larger amount may be that the idling speed of the cold car is high, so more gasoline is burned naturally. There is also a lot of water vapor coming out, and this is related to the thickness of the car’s exhaust and the size of the three-way catalytic mesh. Although his car has just been started, it is not necessarily cold, so there is no need to worry. As long as it does not emit black, blue or yellow smoke, it will be fine.
5. The fuel injection advance angle is small and the combustion is incomplete; the cylinder liner is slightly leaking and the fuel contains water; and white smoke is emitted when the cold engine is started, especially when the engine is started at low temperature, but White smoke occurs as engine temperature rises.
