Exhaust Cam Follower 058109309A

The cam follower, also known as a valve lifter, is a small component that follows the contour of the camshaft lobe. It connects the camshaft to the engine's valves and transfers the motion of the camshaft to open and close the valves at precise intervals. In a car's engine, the camshaft rotates as the pistons move up and down, controlling the timing and duration of the opening and closing of the valves. The cam follower ensures that the valves follow the camshaft's profile accurately, enabling efficient intake and exhaust processes as well as optimal engine performance.
