What Causes the Abnormal Noise in the Cruze Camshaft?

[MaxDella]

The camshaft is one of the key components of the engine. Abnormal noise in the camshaft is usually caused by wear between the camshaft neck and bearings, bending deformation of the camshaft, or lack of engine oil. It is best to have it checked at a 4S shop to avoid affecting the normal operation of the engine. Here is more information about the camshaft: 1. The camshaft is a component in a piston engine, responsible for controlling the opening and closing of the valves. Although in a four-stroke engine, the camshaft's speed is half that of the crankshaft, its speed is still typically very high, and it needs to withstand significant torque. Therefore, the design requires high strength and support for the camshaft, which is usually made of high-quality alloy steel or alloy steel. 2. The camshaft bears periodic impact loads, and the contact stress between the cam and the tappet is very high, with a relatively high sliding speed. As a result, the wear on the cam's working surface is quite severe. To address this, the camshaft neck and the cam's working surface should not only have high dimensional accuracy, low surface roughness, and sufficient rigidity but also high wear resistance and good lubrication properties.
