Piston ring end gaps matter more than you think because they manage pressure and heat, preventing catastrophic failures ...

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?

Most of us consider piston rings little more than a necessary evil. That's probably because grinding rings is a time-consuming chore. And who hasn't accidently ground a gap too large and wasted both ...

The piston rings on any engine have three main purposes - to ensure the combustion chamber’s tightness, to clean the cylinder and to leave a very thin layer of oil on its surface in order to reduce ...
