What is the Crank Connecting Rod Mechanism Composed Of?

[LaJosephine]

The crank connecting rod mechanism is composed of components such as the piston group, connecting rod group, crankshaft, and flywheel group. It serves as the main moving part of the engine to achieve the working cycle and complete energy conversion. During the power stroke, the piston moves linearly in the cylinder under the pressure of the combustion gas, converting this motion into the rotational movement of the crankshaft through the connecting rod, thereby outputting power externally. During the intake, compression, and exhaust strokes, the flywheel releases energy, converting the rotational movement of the crankshaft back into the linear motion of the piston. The function of the crank connecting rod mechanism is to provide a combustion chamber, transform the expansion pressure of the gas generated after fuel combustion acting on the top of the piston into the torque of the crankshaft's rotation, and continuously output power.
