outboard engine camshaft part

The camshaft of an outboard motor is a crucial component responsible for controlling the opening and closing of the engine's valves. It is a cylindrical shaft with multiple lobes or cams, strategically placed to operate the valves at specific intervals. The camshaft is typically made of hardened steel to withstand the high temperatures and pressures within the engine. Single Cylinder Engine Camshaft The lobes on the camshaft are designed with precise contours to determine the valve timing. As the camshaft rotates, the lobes push against the valve lifters or followers, causing the valves to open and close at the right moment. This synchronized movement ensures the proper intake of air and fuel and the efficient expulsion of exhaust gases. In addition to controlling the valve timing, the camshaft also plays a role in other engine functions. It drives the fuel pump, oil pump, and water pump, ensuring the continuous supply of fuel, lubrication, and cooling to the engine components…
