The timing belt is an important part of the engine valve system, ensuring accurate intake and exhaust timing by connecting to the crankshaft and maintaining a certain transmission ratio. The use of a belt instead of gears for transmission is due to the belt's low noise, minimal self-variation, and ease of compensation. 2. The timing belt plays a connecting role, linking the upper part to the timing wheel of the engine cylinder head and the lower part to the crankshaft timing wheel; the timing wheel is connected to the camshaft, which has cams. The contact point is the small rocker arm, and the rocker arm generates pressure through the power brought by the timing belt, serving a lifting function.
