N2 - This paper presents the theoretical procedure to predict the piston slap and its related noise radiation from the engine block. Using this method, the optimum value of the piston pin offset to reduce the impact force and engine noise is determined and compared with the measured one to evaluate the availability of this theoretical method. And it is revealed that piston impact force in the vicinity of the combustion top dead center is controlled by the friction moment around the piston pin and the piston pin offset moment induced by combustion pressure.
