What is piston assembly?

A piston assembly is a crucial component of an internal combustion engine, consisting of the piston itself, piston rings, and often a connecting rod. The piston moves up and down within the cylinder, converting the energy from combustion into mechanical work. The piston rings ensure a tight seal between the piston and the cylinder wall, preventing gas leakage and maintaining compression. This assembly plays a vital role in the engine's overall efficiency and performance.
