Piston rod

From Wikipedia, the free encyclopedia

In a piston engine, a piston rod joins a piston to a connecting rod.

Many internal combustion engines, and in particular all current automobile engines, do not have true piston rods, and the term piston rod is often used as a synonym for connecting rod in the context of these engines.

All engines with crossheads do have true piston rods. These include most steam locomotives and large marine diesel engines.
