Piston slap is the collision of the piston of a reciprocating machine onto the inner surface of the cylinder through the clearance between them due to side forces and moments around the piston pin. It is a source of noise in internal combustion engines and also induces cavitation pitting of their liquid cooled cylinder liners. The authors for the first time clarify the dynamics of the piston slap, so that the calculated velocity and phase of collision near t.d.c. and also near b.d.c. of a 2-stroke cycle simulated combustion engine fairly agree with the measured ones in case the friction forces at five bearing surfaces are appropriately assumed.
