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 ...

This is a preview. Log in through your library . Abstract Inter-ring gas pressure and piston ring motion are considered important for the control of oil consumption, particulate emissions, and reduced ...

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 ...

A new ring pack model has been developed based on the curved beam finite element method. This paper describes the second part of this model: simulating oil transport around the ring pack system (two ...
