EXPERIMENTAL ANALYSIS OF CAM ROLLER OF INTERNAL COMBUSTION ENGINE BY CHANGE IN AREA OF CONTACT

Most of the IC engines used in the market have roll er cam and follower mechanisms, having a line contact between the cam and the roller follower. In a effort to improve the mechanical efficiency of the mechanism the company requires us to change the line contact to a point contact. Hence it is required to change the flat roller follower to a curved profile. The existing cam & follower mechanisms used in Internal Combustion engines have a line contact between them causing frictional losses. These frictional losses in present line contact are being considered on the higher side. These frictional losses affect the total efficiency of an Internal Combustion engine. The mechanical efficiency of cam & follower mechanism i s to be increase by minimising the frictional losses.The roller of rocker arm of a Hero Honda passion bike is replaced by new one to check performance experimentally.
