Abstract
Piston motion affects the thermal efficiency of an internal combustion engine. The efficiency loss due to piston motion is defined as time loss, and accounts for 6 - 7 % of the total loss in a spark ignition engine. In this paper, an analysis is made of the time loss for a conventional slider-crank engine and a perfectly sinusoidal piston motion engine. The heat release rate is modeled using test data from an 1.6 / OHC engine, and parametric studies are made to identify factors affecting thermal efficiencies of engines with conventional and unconventional piston motions.
