Connecting rods are essential components in internal combustion engines, linking the pistons to the crankshaft. They convert the linear motion of the pistons into rotational motion, enabling the engine to produce power. Typically made from materials like steel or aluminum, connecting rods must be strong yet lightweight to withstand high forces during operation. The design of connecting rods varies depending on the engine type, with some featuring a simple I-beam shape while others may have more complex geometries. Proper maintenance and quality materials are crucial, as a failure in the connecting rod can lead to severe engine damage, affecting the overall performance of the vehicle.
