The studies of engine components reveal the cause for the engine vibration and noise. The piston slap due to the impact of the piston in the walls of the cylinder is considered as one of the predominant source of engine noise. In the present work engine performance characteristics are considered. The variation of the torque from minimum to maximum and the corresponding values of the engine performance parameters are logged. The effect of torque on engine speed and on piston movement is studied.

The piston lateral movement is recorded by measuring the gap between cylinder inner wall and the piston skirt for the piston primary motion from TDC to BDC and vice versa. Finite element analysis is carried for von-Mises stress and x-directional displacement for the lateral displacement. The high stress region in the piston is emphasized for the study. It is found that near TDC region the engine is experiencing the maximum impact due to high torque which is the result of combustion pressure and also corresponds to the cause for piston lateral motion in this region.
