What causes white smoke from diesel engine exhaust?

[DiJesse]

Possible causes include a dirty air filter or a blocked exhaust pipe. Below is relevant information about diesel engines: 1. Concept: A diesel engine is an internal combustion engine that obtains energy by burning diesel fuel. The advantages of diesel engines are their high power output and good fuel economy. The working process of a diesel engine shares many similarities with gasoline engines, with each working cycle also going through four strokes: intake, compression, power, and exhaust. 2. Development prospects: The traditional image of diesel engines being heavy, noisy, and emitting black smoke has given many people a poor impression. However, after years of research and application of new technologies, modern diesel engines are vastly different from their predecessors. Modern diesel engines typically employ technologies such as electronic fuel injection, common rail systems, and turbocharged intercooling, achieving significant breakthroughs in weight, noise, and smoke emissions, reaching levels comparable to gasoline engines.
