What are the two major mechanisms of an engine?

The two major mechanisms of an engine are the valve train mechanism and the crankshaft connecting rod mechanism. Below are the relevant introductions about these two mechanisms: Function of the valve train mechanism: According to the working cycle and firing sequence requirements of each cylinder in the engine, it timely opens and closes the intake and exhaust valves of each cylinder, allowing fresh charge to enter the cylinder promptly and exhaust gases to be expelled from the cylinder in time. During the compression and expansion strokes, it ensures the sealing of the combustion chamber. Function of the crankshaft connecting rod mechanism: It provides a place for combustion, converts the expansion pressure of the gas generated after fuel combustion acting on the top of the piston into the rotational torque of the crankshaft, transforms the thermal energy released after fuel combustion into mechanical energy, and continuously outputs power.
