Also known as automotive piston

thumb|upright|Animation of a piston system A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the

AI overview

A piston is a moving part inside a cylinder that seals tightly using special rings, and it's found in engines, pumps, and compressors. It matters because it transfers force between expanding gases (or liquids) and rotating shafts, making it essential for converting the energy in engines or moving fluids in pumps and compressors.

In some engines, the piston also acts as a valve by covering and uncovering ports in the cylinder.
