- The function of the combination of the crankshaft and connecting rods converts the reciprocating motion of the piston into the rotational motion of the crankshaft, and outputs power.

- The connecting rod transmits the motion and power of the piston to the crankshaft, which pushes the crankshaft to rotate.

- The crank bearing receives the force from the connecting rod and converts it into a torque about its own axis, which is then transmitted to the transmission system, while driving the valve train and some other auxiliary devices.
