Valve drive group: camshaft, timing gear, timing chain, timing belt, tappet, pushrod, rocker arm, rocker shaft, and rocker bracket. The functions of the valve train are: 1. To open and close the intake and exhaust valves of each cylinder in accordance with the working cycle and ignition sequence of the engine; 2. To allow the combustible mixture or air to enter the cylinder in a timely manner and exhaust gases to be discharged from the cylinder promptly; 3. To ensure the sealing of the combustion chamber by closing the valves during the compression and power strokes.
