In a conventional application, there are three rings per piston. The top ring is called the compression ring. Its purpose is to seal the combustion gas pressure, transfer heat from the piston to the ...

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?

If asked what you wanted for piston rings in your engine build, would you know how to answer? Piston rings have the most important job in your engine. We will get arguments on this one because there ...
