A mechanical cam in an engine converts rotational motion into linear motion to control the opening and closing of engine valves. As the cam rotates, its specially shaped profile pushes against a follower, which moves vertically to open the valve at precise timing during the engine's cycle. This ensures that the intake and exhaust valves operate efficiently, allowing for optimal airflow and combustion. The design of the cam determines the timing, duration, and lift of the valve movement, critical for engine performance.

Yes it does. But you can not run a mechanical pump on a fuel injected engine. It will not pump enough fuel to run the engine.


What is a cam?

A cam is a mechanical component that converts rotary motion into reciprocating motion. It typically has a non-circular shape to control the movement of other parts within a machine. Cam mechanisms are commonly used in engines, pumps, and other mechanical systems.
