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?

The engine works by taking heat from the hot reservoir, converting some of it into useful work, and rejecting the remaining ...
