camshafts
Valve-timing rods
Camshafts is the plural of camshaft, a rotating shaft with lobes (cams) that convert rotational motion into linear motion.
In internal combustion engines, the camshaft controls the opening and closing of intake and exhaust valves: The mechanic replaced both camshafts during the rebuild.
High-performance engines often feature multiple camshafts for precise valve timing.
