What causes the starter to smoke?

[BrynleeAnn]

The reasons for the starter smoking are: 1. The engine temperature is too low: some diesel fuel does not burn and turns into oil vapor, which is discharged from the exhaust pipe along with the exhaust gas; 2. There is water in the fuel supply system: water in the fuel or combustion chamber is heated by the heat released during combustion in the cylinder and turns into steam, which is discharged from the exhaust pipe, forming white smoke; 3. The fuel injection timing is too late: due to the delayed injection timing, the cylinder temperature has already dropped when fuel is injected, causing some diesel fuel to not burn and turn into oil vapor, resulting in white smoke; 4. Poor atomization of the fuel injector: poor atomization leads to incomplete combustion of diesel fuel, which mixes with the high-temperature exhaust gas from normally operating cylinders in the exhaust pipe, causing white smoke; 5. The cylinder pressure is too low.
