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

Engine building is technically a science, but the truth is that there is just as much art as there is science. Where most might think that the “art” part of engine building is in the design and ...

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 ...
