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 ...

The motion of the top and second piston rings and pressures at the top land and intermediate land were recorded in an operating single cylinder engine. The parameters were measured on a tight top land ...

This paper reviews piston and ring friction which can account for 65% of the mechanical friction in an internal combustion engine. It shows that cylinder liner lubrication is predominantly ...
