The irregular occurrence of noise which is caused by the interaction of piston pin and piston pin boss is subjectively perceived as extremely annoying. The effect of shock excitation, related to pin and pin boss, on airborne and structure-borne noise in a gasoline engine with floating pin design will be presented. The dependency on water temperature and engine speed in shock excitation will be shown. The measurement procedure for detecting piston pin noise and the evaluation method for quantification in the time range will be described. Using examples the influence of different parameters on piston pin noise such as pin fitting clearance and various pin bore geometries will be presented.
