The basic mechanism of a piston
Release date:
2019-05-15
【SUMMARY】 The piston is a reciprocating component housed within the cylinder block of an automobile engine. Its basic structure is divided into three main sections: the crown, the head, and the skirt. The piston crown forms the primary part of the combustion chamber, and its shape depends on the specific type of combustion chamber design used. Gasoline engines typically employ flat-top pistons, which offer the advantage of a smaller heat-absorbing surface area. In contrast, diesel engine pistons often feature various types of recessed cavities in their crowns; the exact shape, location, and size of these features must precisely match the requirements for air-fuel mixture formation and combustion in the diesel engine.
