Under normal circumstances, the exhaust gas from the car is almost invisible (unless it is seen in the lower winter temperatures). But when there is a problem with the car engine, the exhaust gas will change significantly. We can often see that some cars emit white smoke, some blue smoke, and some black smoke. So what do these situations mean?
Car cylinder bed (mat) damage, mainly caused by high temperature, because the oil has a good heat dissipation effect, the high temperature will burn the cylinder bed, but the cylinder bed is broken, the engine will appear weak, sometimes white smoke, row The trachea is flooding, there may be organic oil in the tank, or water in the oil pan.
Cylinder pad ablation is a very common failure for diesel engines used in some large trucks. So what are the faults in the cylinder head ablation? How should we judge? What are the precautions for changing the cylinder head? Let's talk about this issue below.
At present, there are several types of cylinder head gaskets that are used more frequently:
The cylinder head gasket is located between the cylinder head and the cylinder block, also called the cylinder bed. Its function is to fill the microscopic pores between the cylinder block and the cylinder head, to ensure a good sealing at the joint surface, thereby ensuring the sealing of the combustion chamber to prevent the cylinder from leaking. And the water jacket leaks.
