The valve camshaft, code P50705-12, is an integral part of the MAN L21/31 engine’s valve train system. It precisely actuates the engine’s intake and exhaust valves through its lobes, transforming rotational motion into linear valve movement. Engineered for high-strength and dimensional accuracy, the camshaft is responsible for the precise timing and duration of valve opening, directly influencing combustion efficiency, engine output, and emissions. Its robust design supports long service intervals even in demanding marine and industrial environments.
