Pistons are a fundamental part of a piston combustion engine. The engine pistons mediate energy transfer between the combustion chamber and the moving mechanism connected to the pistons.

This article will shed light on pistons' function, construction, material, and what forces they need to withstand.

Piston rings are part of a piston combustion engine and separate the combustion chamber from the crankcase. In addition, they also serve to define the clearance between the piston and the cylinder.

In this article, we'll take a quick look at the function of piston rings, their breakdown, and what a worn piston ring can cause.
