Camshaft lobe diagram

WebAs the camshaft turns, the cam lobe brings the tappet upward. When the tappet moves up, it pushes the push-rod and one end of the rocker arm upwards. The other end of the rocker arm’s tip moves downward and the inlet valve opens against the spring’s tension. When the cam lobe reaches the maximum height, the valve opens fully. WebThe cam's centerline specification is used to determine the position of the lobes on both the cam and as installed in the engine. Most cam companies include an intake centerline number, which is the position of the intake …
