The function of the crank linkage
The function of the crank-link mechanism is to provide a combustion place, which converts the expansion pressure of the gas generated by the combustion of the fuel on the top of the piston into the torque of the crankshaft rotation, and continuously outputs power.
(1) Changing the pressure of the gas into the torque of the crankshaft
(2) Changing the reciprocating motion of the piston into the rotational motion of the crankshaft
(3) Converting the force of combustion on the top of the piston into the torque of the crankshaft to output mechanical energy to the working machine
