Principle app timing7/11/2023 This camshaft has a cam and its contact point It is a small rocker arm. The upper connection is the timing wheel of the engine cylinder head, and the lower connection is the crankshaft timing wheel the timing wheel is connected to the camshaft. The function of the timing belt is to link up and down. The piston lifts are coordinated with each other, and the timing belt acts as a "bridge" in the engine, and transmits power to the corresponding parts under the drive of the crankshaft. It is connected with the crankshaft and matched with a certain transmission ratio to ensure the accuracy of the intake and exhaust time.ĭuring the working process of the automobile engine, the four processes of intake, compression, explosion, and exhaust occur continuously in the cylinder, and the timing of each step must be matched with the movement state and position of the piston, so that the intake and exhaust can be combined with each other. The timing belt is an important part of the engine's air distribution system.
