Abstract

This paper presents the analytical method to evaluate the impact force and engine noise induced by piston slap considering the detailed piston profile. This method is applied to examine the effect of the piston profile on piston slap impact force and frequency spectrum related to the engine noise. The tendency of the piston pin offset to abate the piston slap is compared with the measured one to confirm the availability of this method. And it is pointed out that piston movement in the vicinity of the combustion top dead center is governed by the friction moment around the piston pin and the additional piston pin offset moment induced by combustion pressure.
