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

The connecting rod serves as a crucial component in an engine's function by connecting the piston to the crankshaft. This connection is essential for transforming linear motion from the piston, which moves up and down in the cylinder due to combustion events, into rotational motion for the crankshaft. The crankshaft then converts this rotational motion into the power that drives the vehicle.

The design of the connecting rod allows it to handle the significant forces and stresses generated during the combustion process, making it a critical part of the engine's overall performance and efficiency. This direct linkage between the piston and crankshaft is fundamental to the operation of any internal combustion engine, ensuring that the mechanical energy produced during combustion is effectively harnessed for propulsion.
