What is the general fault of the engine piston of a car
Possible faults are
1 When the cylinder is pulled, the piston cannot be lubricated, which causes dry friction of some parts on the piston and damages the cylinder. The other is that if the piston ring is not cooled in time, the piston ring will expand due to heat, which will cause the cylinder to die and form a cylinder pull. In severe cases, it may cause the crankshaft to bend and deform.
2 Air leakage, oil leakage, the piston ring on the piston is not installed properly, or it is installed incorrectly, which may cause the sealing performance to decrease, resulting in air leakage and oil leakage. This is why some cars always burn oil. The oil is burned due to the oil leakage of the piston ring.
3 Loose piston pin. The piston pin is an important part that connects the connecting rod and the piston. Its looseness may cause the power transmitted by the piston to the crankshaft to decrease, resulting in increased fuel consumption.
