What Causes Engine Shaking and White Smoke?

[LeJoshua]

There are many reasons for engine shaking and white smoke, mainly including the following aspects: 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, resulting in white smoke. 2. Water in the fuel supply system: There is water in the fuel or combustion chamber. The water is heated into steam by the heat released during combustion in the cylinder and is discharged from the exhaust pipe, forming white smoke. 3. Injection timing is too late: Due to the late injection timing, the cylinder temperature has already dropped when the fuel is injected, causing some diesel fuel to turn into oil vapor without burning, resulting in white smoke. 4. Poor fuel injector atomization: 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, resulting in white smoke. 5. Cylinder pressure is too low: Some diesel fuel turns into oil vapor without burning, thus causing white smoke from the exhaust pipe.
