Authors Abstract
Content
A new method for measuring friction has been developed in order to analyze piston and piston ring assembly friction force during engine operation. While this method does not require extensive modification to the piston or cylinder, two extra compression and expansion strokes each are added at the end of the conventional four-stroke cycle. In these measuring strokes, the gas pressure and temperature are maintained at firing levels, and friction force characteristics of the piston and piston ring assembly are measured continuously while the burned gas is compressed and expanded.
