Which engine component transfers the power of the piston to the crankshaft?

The connecting rod is the component that transfers the power generated by the piston during its movement to the crankshaft. As the piston moves up and down within the cylinder due to the combustion of fuel, the connecting rod changes this linear motion into rotational motion. The upper end of the connecting rod is attached to the piston, while the lower end connects to the crankshaft. This relationship allows the engine to convert the piston's energy into a form that can be used to turn the crankshaft, ultimately powering the vehicle.

In the context of engine functioning, the camshaft operates separately by controlling the timing of the opening and closing of the engine's valves, while the flywheel stabilizes the rotational motion of the crankshaft, smoothing out power delivery. The block refers to the engine's main structure, housing the cylinders and facilitating other components but does not directly participate in power transfer between the piston and crankshaft. Thus, the connecting rod plays a crucial role in the engine's operation by linking the linear movement of the pistons with the rotational movement of the crankshaft.
