Cause of a large number of white smoke emitted from automobile exhaust pipe
When the engine is running, the exhaust pipe discharges a large amount of white smoke. There are two kinds of situations:
1, exhaust pipe discharge of milk white oil mist.
The main reason is the poor fuel vaporization, no combustion will be discharged from the exhaust pipe, and the formation of milky white smoke. In winter, when the engine starts, it is common, because the temperature is low, the fuel atomization is bad. Usually after the start of the engine with the engine temperature will disappear.
2, a large amount of water vapor exhaust white smoke, and I have a water exhaust pipe.
The main reason is the cooling water into the cylinder or gasoline containing water and the formation of water vapor caused by.
Exhaust pipe to discharge a large number of white smoke fault maintenance:
1, in the winter or rainy season in the car when the initial launch, often can see the white smoke. It does not matter, once the engine temperature rise, the white smoke will disappear, this situation does not need to overhaul. If the engine temperature is increased, the exhaust pipe into black smoke, then indicate that the cylinder pressure is too low or individual cylinder does not work, should be checked and excluded.
2, when the engine running exhaust pipe exhaust a lot of water vapor, should check whether there is water inside the tank, check the cylinder gasket is damaged, whether there are cracks in the cylinder, the cylinder seal ring is good, etc..
