This Paper deals with the analysis of lubrication exaggerated by the secondary motion of the piston. The technique is use to make a mathematical model of piston. It is analyze on MATLAB using Gauss Seidel iterative method to get the required results and see the effects on lubrication layer caused by piston tilt. The technique used in this research is by discretizing the equations and making matrices of the required forces for different crank angles. Also mesh is being generated at piston skirt. Across each node of mesh the effect of lubrication layer was observed. The results showing the lubrication regimes changes and affect piston secondary motion.
