DESCRIPTION
The Engine Piston Kit, also known as a piston assembly, is a critical component of an internal combustion engine. It consists of a piston, piston rings, and wrist pin. The piston is a cylindrical piece of metal that moves up and down within the cylinder bore. The piston rings seal the gap between the piston and cylinder walls to prevent oil from entering the combustion chamber while also providing a compression seal to maximize engine power. The wrist pin connects the connecting rod to the piston and allows for reciprocating motion. The Engine Piston Kit is designed to withstand high temperatures and pressures generated by combustion in order to convert fuel into mechanical energy that powers the vehicle's wheels.
