What is the reason why the truck emits white smoke?

There is too much water in gasoline, which can be solved by cleaning the throttle; If the gasoline contains moisture, check whether there is water leakage or oil leakage at the joint between the cylinder head and the cylinder gasket. If there is, it means that the cylinder gasket is damaged, resulting in leakage.

Normal white smoke is caused by the high temperature of the exhaust gas from the exhaust pipe and the condensation of water vapor into small water droplets. If it is large, it may be that a piston of the engine is broken and the oil starts to burn. The thick white color in the exhaust gas is naturally due to the high water content in the exhaust gas. There are two reasons for this: there is too much water in gasoline; Or the waterway gasket is damaged, the cylinder liner is damaged, and cooling water enters the cylinder.

When a car emits blue smoke, it is usually a real fault. This situation is generally caused by a large amount of engine oil entering the cylinder and not completely burning. If the spark plug is removed, serious carbon deposit will be found.

At this time, it is generally necessary to check whether the oil level of the dipstick is too high, whether the gap between the cylinder and the piston is too large, whether the piston ring is installed backwards, whether the intake valve guide tube is worn, whether the sealing ring is damaged or whether the cylinder gasket is ablated. , find the problem and fix it in time.
