The white smoke may be caused by the wear of the cylinder gasket of the engine cylinder, resulting in a certain gap, which leads to a large amount of water in the cooling system entering the combustion chamber. Water can't burn, and when heated, it produces steam, which is directly discharged from the exhaust pipe.
Causes of black smoke from automobile exhaust pipe: the phenomenon of black smoke is more common in carburetor cars. This is because the fuel injection quantity of carburetor model is not controlled by computer, but by pedal accelerator. In some cases, too much fuel enters the cylinder and is discharged from the car before burning, which causes the black smoke we see.
