What is the function of the camshaft?
1 Answers
Automobile camshaft is responsible for controlling the opening and closing of the valves. Below are the key points about the camshaft: 1. Camshaft: It is a component in piston engines. Although in four-stroke engines, the camshaft rotates at half the speed of the crankshaft, its rotational speed is still very high, and it needs to withstand significant torque. Therefore, the design requires high strength and robust support for the camshaft, which is typically made of high-quality alloy steel or alloy steel. 2. If: The oil pump fails to provide sufficient oil pressure due to prolonged use, or the lubrication passages are blocked preventing oil from reaching the camshaft, or the bearing cap fastening bolts are over-tightened preventing oil from entering the camshaft clearance, all these can lead to abnormal wear of the camshaft. 3. Abnormal wear of the camshaft: This can cause an increase in the clearance between the camshaft and the bearing seat, leading to axial displacement of the camshaft during operation, which in turn produces abnormal noise. 4. When installing the bearing cap: Pay attention to the directional arrows and position numbers marked on the surface of the bearing cap, and strictly follow the specified torque using a torque wrench to tighten the bearing cap fastening bolts.
