Engine piston

An engine piston is a cylindrical part that reciprocates inside a cylinder and serves to convert a change in gas, vapor or liquid pressure into mechanical work, or vice versa - a reciprocating movement into a pressure change. Initially, pistons for automobile internal combustion engines were cast from cast iron. With the development of technology, they began to use aluminum, because it gave an increase in speed and power, less stress on parts, better heat transfer. Functions: provides the transfer of mechanical forces to the connecting rod, is responsible for sealing the fuel combustion chamber, ensures timely removal of excess heat from the combustion chamber.
