DESCRIPTION
The Engine Piston Kit is a set of components that includes the piston, piston rings, and wrist pin. These parts work together to transfer energy from the combustion process to the engine's crankshaft. The piston is a cylindrical component that moves up and down in the engine cylinder, compressing fuel and air during the intake stroke and then pushing exhaust gases out during the exhaust stroke. The piston rings help create a tight seal between the piston and cylinder walls to prevent loss of compression or oil leakage. The wrist pin connects the connecting rod to the piston. A high-quality Engine Piston Kit can improve engine performance, increase fuel efficiency, and reduce emissions.
