• The gas pressure is endured, and the crankshaft is driven to rotate through the connecting rod by the piston pin, converting the thermal energy generated by combustion into mechanical energy to provide power for the car.
• The piston rings are installed on the head, and the skirt guides the reciprocating motion of the piston and withstands the lateral pressure.
• It can shorten the height of the engine block and the entire engine, reduce the volume, weight, metal consumption and cost of the engine, and at the same time reduce the reciprocating mass.
• To reduce friction work and improve mechanical efficiency.
• The combustion chamber is sealed by the tight fit of the piston ring and the cylinder wall.
