Analysis of CAM Shaft

The camshaft is an apparatus often used in piston engines to operate poppet valves. It consists of a cylindrical rod running the length of the cylinder bank with a number of oblong lobes or cams protruding from it, one for each valve. The cams force the valves ¬open by pressing on the valve, or on some intermediate mechanism, as they rotate. The diesel engine 523 camshaft are generally made by EN19 (carbon steel) Steel material. However, EN19 steel material has low wear resistance and its service life is shorter. In camshaft, particularly lobes suffer wear over time to a point where valve lift is reduced and engine performance is degraded. Also it necessitates frequent replacement leading to loss of time and money. In this projects we are analyzing and comparing mechanical properties of EN 41 B (Nitride steel) Over EN 19 & EN 351 (alloy steel) steel.
