The connecting rod links the piston to the crankshaft, transmitting the forces acting on the piston to the crankshaft and converting the piston’s reciprocating motion into the crankshaft’s rotational motion, while simultaneously transmitting force and torque. Key dimensions such as the coaxiality and center distance between the big end and small end of the connecting rod are critical to ensuring the connecting rod’s functionality, reliability, and the overall performance of the engine.
