What causes camshaft signal distortion in the Besturn B50?
1 Answers
It refers to an unreasonable signal from the camshaft position sensor. The causes for this fault code include: sensor interference; intermittent circuit faults (intermittent open circuits or short circuits); foreign objects between the sensor and the target wheel, or excessive installation gap; damage or looseness of the target wheel. Introduction to the Camshaft: The camshaft is a component in a piston engine. Its function is to control the opening and closing of the valves. Although in a four-stroke engine, the camshaft's rotational speed is half that of the crankshaft (in a two-stroke engine, the camshaft's speed is the same as the crankshaft), its speed is generally still very high, and it needs to withstand significant torque. Therefore, the design requires high strength and support for the camshaft, and it is usually made of high-quality alloy steel or alloy steel. Since the valve movement pattern affects an engine's power and operational characteristics, camshaft design plays a crucial role in the engine design process. Camshaft Structure: The main body of the camshaft is a cylindrical rod approximately the same length as the cylinder group. It is fitted with several cams that drive the valves. The camshaft is supported within the camshaft bearing bore by camshaft journals. The number of camshaft journals significantly affects the camshaft's support stiffness. If the camshaft lacks sufficient stiffness, it may bend and deform during operation, affecting the valve timing.
