Reduced Friction Power Cell Components 2000-01-3321

This paper describes the development of a low friction power cell (piston, piston rings, connecting rod and bearings) for a spark-ignition 1.0 liter engine with the help of mathematical simulations.
Using numerical modelling, small variations in friction power loss can be studied, which would be impossible by actual engine tests due to uncertainties in measurement process.
Although it was not possible to experimentally quantify the individual component gains, the increase in engine brake power measured with the engine running with the original and modified power cells correlates very well with the simulated values.
