description

Engine Camshaft controls the timing and movement of intake and exhaust valves for the right side of a multi-bank engine. It translates rotational motion into linear movement through a series of lobes that push against valve lifters and rocker arms. Ensures that valves open and close in an accurate sequence with piston movement to manage air-fuel intake and exhaust expulsion.
