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 ...

SAE Transactions, Vol. 97, Section 2: JOURNAL OF MATERIALS (1988), pp. 393-402 (10 pages) In current designs of the automotive (kinematic) Stirling engine, the piston rings are made of a reinforced ...

A new technique termed the "fixed sleeve" method has been developed to measure the instantaneous friction of the piston and ring assembly as a function of crank angle. This method is a derivative of ...
