![]() Separate camshafts are provided for using the fuel pump in the engine.Ĭredit: h ttps://Cam and Follower in Industries Cam automatic latheĪn automatic cam lathe is a machine in which the movements of tools are controlled by the cam and follower mechanism. The fuel pumps are operated by a cam and follower mechanism similar to the valves. In a Diesel engine, the only air is added to the cylinder in the suction stroke after compressing the air to high temperature and pressure, fuel is injected through a fuel pump. The fuel pumps are used in the Diesel engine. Operation of the fuel pump in Diesel engine The figure shows two camshafts, one for the exhaust valve and one for the suction valve. The number of camshafts varies with the engine. ![]() Hence, the camshaft is driven by the engine itself. The camshaft is linked with the crankshaft through a chain or belt drive or gear mechanism. Generally, an engine consists of multiple cylinders hence, each cylinder requires a cam mechanism. Generally, a radial plate cam with a flat-faced or spherical follower is used. The accurate opening of these valves is operated by a cam and follower mechanism. The suction valve should open during air intake to the cylinder, and the exhaust valve should open to remove the combustion product. Those valves have to be opened accurately for the better performance of the IC engine. There are two valves in a four-stroke IC engine. Cam and follower in IC engine Valves in IC Engine
