What are the causes of white smoke from the engine?

[HarrisonMarie]

The causes of white smoke from the engine are: 1. The purchased fuel is of low quality with high water content; 2. The water-fuel separator is malfunctioning, unable to separate water from the fuel; 3. Damage to the cylinder liner or cylinder gasket, allowing coolant to enter the cylinder, where it mixes with fuel and burns under high temperature and pressure, producing a large amount of water vapor; 4. The fuel injector is faulty, spraying fuel in droplet form, which mixes with air and is compressed to raise the temperature, causing the fuel to turn into vapor directly without combustion; 5. The fuel injection timing is adjusted too small, resulting in a smaller amount of fuel sprayed by the injector before combustion, reducing the amount of pre-mixed gas, slowing down the combustion speed, and prolonging the end time of combustion, forming white mist.
