Repeated cycles of searing combustion heat alternating with cool incoming air and fuel, extreme load reversal, thrust forces that slam the pistons into the cylinder wallsits quite amazing that ...

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 ...

There's no need to sugarcoat what bad piston rings can do to your engine. Those rather thin cast-iron or steel rings may look small and irrelevant to untrained eyes, but they play a vital part in ...

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 ...

Pistons reciprocate inside the cylinders of an internal combustion engine. The outer diameter of the piston is slightly smaller than that of the cylinder liner, enabling it to move up and down with ...

Engineered using the OEM CAD models to clear the OEM piston cooling oil jets and crankshaft reluctor wheel of the LSA engine, the Lingenfelter LSA piston and ring kit will also work alongside ...

If asked what you wanted for piston rings in your engine build, would you know how to answer? Piston rings have the most important job in your engine. We will get arguments on this one because there ...
