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

We might be covering ground that's well trampled for many, but the static compression ratio of an engine is simple to understand: it's all the volume of a cylinder above the compression ring at Bottom ...

The folks at TRW have come up with a revolutionary idea for reducing the piston ring drag of the top compression ring. It is called the Pressure Balance Ring (PBR). Essentially, the PBR design amounts ...

Piston ring grooves serve a larger purpose than simply supporting the rings. They impact combustion sealing, oil control, friction, and many more engine attributes. Wiseco is a world leader in piston ...
