Why Do Diesel Vehicles Emit White Smoke?

Diesel vehicles emit white smoke due to the following reasons: 1. Insufficient combustion temperature: When the engine temperature is too low, the fuel injected into the cylinder forms a mixture with air that cannot fully combust, resulting in white smoke from the exhaust pipe. 2. Water in the diesel fuel: The presence of water in diesel directly affects the normal combustion of the mixture, causing white smoke. 3. Delayed fuel injection: If the fuel injection timing is too late, the cylinder temperature has already dropped by the time of injection, causing some diesel to turn into vapor without burning, leading to white smoke. 4. Poor fuel injector atomization: Inadequate atomization prevents the diesel from burning completely, and when it mixes with the high-temperature exhaust gases from normally functioning cylinders in the exhaust pipe, white smoke is produced. 5. Low cylinder pressure: Some diesel turns into vapor without burning, thus emitting white smoke from the exhaust pipe.
