The valve cam K 42160 is a precision timing and control component mounted on the camshaft of the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 engine, where it plays an essential role in controlling the mechanical operation of the corresponding valve mechanism. Its accurately defined cam profile converts camshaft rotation into precisely timed movement, helping ensure that the associated valve opens and closes at the required points of the engine operating cycle and follows the intended lift characteristics. Because valve timing directly influences gas exchange and overall engine performance, the geometry, angular position, surface finish, and dimensional accuracy of the K 42160 are particularly important. During operation, the valve cam is subjected to repeated contact stresses, cyclic loading, friction, vibration, and prolonged heavy-duty service, requiring good wear resistance, correct alignment, and effective lubrication of the associated contact surfaces. During overhaul, the cam profile and mating components should be inspected for wear, pitting, scoring, deformation, or other surface damage that could alter valve motion. By providing accurate and repeatable mechanical control of the valve mechanism, the K 42160 valve cam contributes to correct valve timing, efficient gas exchange, stable engine operation, and dependable long-term performance of the ZV40/48 engine.
