What is one function of a connecting rod in an engine?

The connecting rod serves a crucial function in the operation of an internal combustion engine by connecting the piston to the crankshaft. This component transmits the linear motion of the piston, which occurs during the combustion process, into the rotational motion of the crankshaft. As the piston moves up and down within the cylinder, the connecting rod converts this motion into a rotating action that ultimately drives the vehicle's wheels.

The relationship between the piston and the crankshaft, mediated by the connecting rod, is fundamental to the engine's power generation. This motion conversion is essential for the engine's overall efficiency and performance, making the connecting rod a key element in the engine assembly.
