camshaft
Engine valve controller
A camshaft is a rotating shaft fitted with cams—lobed projections that convert rotational motion into reciprocal motion.
In internal combustion engines, the camshaft controls the opening and closing of valves, determining when fuel enters the cylinder and when exhaust exits.
The shape and timing of the cams directly affect engine performance.
The mechanic said the camshaft needed replacing.
Camshafts also appear in other machinery requiring precisely timed mechanical action.
