Diesel Engine exhaust white smoke is not fully atomized and burned fuel particles or water vapor, not atomized fuel or water into the cylinder will make the exhaust white smoke. The main reasons are the followings:
1. Low temperature and insufficient cylinder pressure, poor fuel atomization, especially initial period of the cold start;
2. Cylinder gasket damage, cooling water into the cylinder;
3. Cylinder block crack, cooling water into the cylinder;
4. Much water in fuel.
The exhaust has white smoke when cold start, the white smoke will disappear after warming up the engine, which should be regarded as normal. But if after the normal operation of the vehicle, there is still white smoke, which is regarded as failure. So some inspection and analysis should be made to troubleshoot: if water in the water tank has phenomenon of abnormal consumption, if the cylinder works normally, if oil and water separator has too much water.
