Engine piston set

Piston is a reciprocating movement in the cylinder body of an automobile engine. 1. The basic structure of the piston can be divided into top, head and skirt. The top of the piston is the main part of the combustion chamber, and its shape is related to the selected combustion chamber form. 2. Gasoline engines mostly use flat-top pistons, which have the advantage of small heat absorption area. 3. The top of the diesel engine piston often has a variety of pits, and its specific shape, position and size must be adapted to the formation and combustion requirements of the diesel engine mixture.
