• The secondary movement of the piston within the piston-cylinder clearance was measured on a small automotive IDI diesel engine. A total of six inductive transducers were installed on the piston skirt to measure the clearance. Slap-induced vibration measurement was made on the liner, the cylinder block and the head bolt. The effects of the gudgeon pin off-set, the engine speed and the load on the piston slap phenomena are discussed. Some of the experimental results of the piston secondary movement are compared with the numerically simulated movement of the piston. It is suggested that the profiles of the piston skirt and the cylinder have also important effects on the impulse of the piston slap.
