• It can reduce mechanical noise and vibration and improve the overall performance and comfort of diesel engine.
• Control the opening and closing of the valve: the camshaft controls the opening and closing timing of the valve by cooperating with the valve mechanism.
• Through the rotation of camshaft and the shape design of cam, the working state of valve and piston can be effectively controlled and coordinated to avoid collision and wear.
• Control the timing of fuel injection: In diesel engines, the camshaft and the fuel injection pump are connected by a connecting rod to control the timing and quantity of fuel injection.
• Driving other accessories: Camshafts are usually directly connected to the crankshaft, and the rotating motion of the crankshaft is transmitted to other accessories, such as generators and cooling water pumps, through gear transmission.
