It's a well-known fact that piston ring gaps represent an area of pressure loss in a running engine. It has been found that minimizing end gap under operating conditions offers a measurable power ...

In a conventional application, there are three rings per piston. The top ring is called the compression ring. Its purpose is to seal the combustion gas pressure, transfer heat from the piston to the ...

Regulating heat and pressure inside an engine is necessary for its healthy operation. Piston ring end gaps play a vital role in that, but they can be easily overlooked as a minor measurement. In ...

No matter how much we love them, our engines are still basically inefficient air pumps and need all the help they can get to make power. Like any other type of pump, if it leaks, it won't work. And ...
