Definition
A camshaft is a rotating shaft within an engine that contains cams, which are shaped protrusions. These cams operate valves, controlling the intake and exhaust of gases in the engine's cylinders. It's like the brain of the valve system, precisely timing the opening and closing of valves. Unlike a crankshaft, it focuses solely on valve operation. It's a crucial component for engine performance and efficiency. Its precise engineering ensures smooth engine function.
