What is difference between piston rod and connecting rod?
A piston rod connects the piston to the crankshaft in an engine, transmitting the force from the expanding gas to the crankshaft to generate motion. A connecting rod connects the piston to the crankshaft, converting the linear motion of the piston into rotational motion to drive the crankshaft. In summary, the piston rod is part of the piston assembly, while the connecting rod is part of the crankshaft assembly in an engine.
