What Causes White Smoke from the Front Hood of a Car?

[VanDylan]

Detailed reasons and solutions for white smoke from the front hood of a car are as follows: 1. Engine temperature is too low: Some diesel fuel turns into oil vapor without burning and is discharged from the exhaust pipe along with the exhaust gas, causing white smoke. Solution: Preheat the engine. 2. Poor fuel injector atomization: Poor atomization leads to incomplete combustion of diesel fuel, which mixes with the high-temperature exhaust gas from normally working cylinders in the exhaust pipe, resulting in white smoke. Solution: Replace the fuel injector. 3. Cylinder pressure is too low: Some diesel fuel turns into oil vapor without burning, thus causing white smoke from the exhaust pipe. Solution: Go to a repair shop for maintenance.
