Why is the tractor emitting white smoke?

[VonRebecca]

The reasons for a tractor emitting white smoke are as follows: White smoke emission: When the diesel engine has delayed fuel injection, low injection pressure, or poor atomization, it can lead to white smoke emission. During cold starts in winter, white smoke from the exhaust pipe is normal and will gradually disappear after running for a while. Poor atomization of the fuel injector: Poor atomization causes incomplete combustion of diesel, resulting in white smoke. Repairing the fuel injector can solve this issue. Low cylinder pressure: Some diesel fuel turns into oil vapor without being burned, leading to white smoke from the exhaust pipe. Damaged cylinder gasket: If the engine has been used for a long time, the cylinder gasket may be damaged or the cylinder itself may be worn out, allowing coolant to enter the cylinder. In this case, replace the cylinder gasket and tighten the cylinder head bolts strictly in order using a torque wrench. It could also be due to uneven contact between the cylinder head and the cylinder block after prolonged use, requiring the cylinder surface to be ground flat with specialized equipment.
