The piston of the engine is one of the main parts in the engine. It forms a piston group with piston rings, piston pins and other parts, and forms a combustion chamber together with the cylinder head, which bears the force of gas and transmits power to the crankshaft through the piston pin and connecting rod. , to complete the working process of the internal combustion engine.
The piston ring is a metal ring used to embed into the groove of the piston. There are two types of piston rings: compression rings and oil rings. The compression ring is used to seal the combustible mixture in the combustion chamber; the oil ring is used to scrape excess oil from the cylinder. The piston ring is a metal elastic ring with large outward expansion deformation, which is assembled into the annular groove corresponding to the cross section. Reciprocating and rotating piston rings rely on the pressure difference of gas or liquid to form a seal between the outer circular surface of the ring and the cylinder and one side of the ring and the ring groove.
Generally, the piston is a cylindrical body. According to the working conditions and requirements of different engines, the structure of the piston itself is various. Generally, the piston is divided into three parts: the top part, the head part and the skirt part. The piston skirt refers to all the parts below the piston ring groove, which is called the piston skirt. Its function is to keep the vertical posture of the piston during the reciprocating motion as much as possible, that is, the guiding part of the piston.
