Intake VVT sprocket for changan Alsvin CS15

This intake camshaft sprocket is suitable for Changan CS15

The intake camshaft sprocket is a key component that controls valve opening and closing, and is crucial for engine performance and durability. ‌

The intake camshaft sprocket, as a part of the camshaft, controls the opening and closing actions of the valves. In a four stroke engine, although the speed of the camshaft is half that of the crankshaft, its speed is still high and it needs to withstand a large amount of torque. Therefore, the design of camshafts plays a very important role in engine design. The material of the camshaft is generally high-quality alloy steel or alloy steel, because the contact stress between the cam and the tappet is high, and the relative sliding speed is also high, resulting in severe wear on the working surface of the cam. In order to cope with this situation, the camshaft journal and cam working surface should not only have high dimensional accuracy, small surface roughness, and sufficient rigidity, but also have high wear resistance and good lubrication. In addition, the side of the cam is designed in an egg shape to ensure sufficient intake and exhaust of the cylinder, while considering the durability and smoothness of the engine operation, to avoid excessive impact on the valves due to the acceleration and deceleration process during opening and closing actions, which may cause serious wear, increased noise, or other serious consequences. ‌
