There's no need to sugarcoat what bad piston rings can do to your engine. Those rather thin cast-iron or steel rings may look small and irrelevant to untrained eyes, but they play a vital part in ...

Heat is a byproduct of combustion. Both air-cooled and water-cooled engines need to dissipate that heat to keep the engine from running too hot. Can piston rings play a role in managing that heat?

But when done right, piston rings can create a power advantage by maximizing dynamic engine compression while still maintaining good oil control. This involves both proper selection for the intended ...

Unless you drive a Wankel rotary, your combustion engine vehicle has pistons, and each of those pistons has three rings. Why ...
