The single-cylinder engine camshaft is a crucial component in the engine's valve timing system. It is responsible for opening and closing the intake and exhaust valves at the correct time, ensuring optimal engine performance.
The camshaft is typically located in the engine block and is driven by the crankshaft through a timing belt or chain. It consists of a series of lobes or cams, which are strategically positioned to control the valve movement.
Outboard Engine Camshaft
During the engine's combustion cycle, the camshaft rotates, causing the lobes to push against the valve lifters or followers. This action lifts the valves, allowing the air-fuel mixture to enter the combustion chamber during the intake stroke and exhaust gases to exit during the exhaust stroke.

The design of the camshaft is crucial in determining the engine's power output and efficiency. The shape and size of the lobes, known as the cam profile, dictate the valve lift an…
