What Causes White Smoke and Water Dripping from the Exhaust of a Diesel Engine?

[MacKennedy]

White smoke and water dripping from the exhaust of a diesel engine indicate that the coolant from the radiator has entered the engine interior, usually due to a damaged cylinder head gasket. Coolant, also known as antifreeze coolant, prevents the cooling liquid from freezing during cold winter parking, which could otherwise crack the radiator or damage the engine cylinder block. Many people believe that antifreeze is only used in winter, but in fact, it should be used year-round. A diesel engine is an engine that burns diesel fuel to release energy, with advantages including high torque and good fuel economy. The working process of a diesel engine shares many similarities with that of a gasoline engine, with each working cycle also going through four strokes: intake, compression, power, and exhaust.
