One of the key reasons why the slotted link mechanism is not predominantly used in IC engines is the fundamental difference in how the reciprocating motion is initiated and controlledBasic kinematic concepts and definitions In an IC engine, the piston's movement is directly a consequence of the high-pressure gases generated by the combustion of the fuel-air mixture within the cylinder4, crank and slotted lever quick return motion mechanism.
