The upper and lower ends of the push rod are heat-treated and polished to improve wear resistance; the rod body has two types: solid and hollow. [Engine valve mechanism] The function of the valve mechanism is to open and close the intake and exhaust valves in time according to the working sequence of the engine and the requirements of the working cycle of each cylinder, so that the combustible mixture (gasoline engine) or fresh air (diesel engine) engine) into the cylinders and expel the exhaust gases into the atmosphere.
