Car connecting rods play a crucial role in the smooth operation of an engine's internal combustion system. These essential components connect the piston to the crankshaft, ensuring the efficient transfer of force. By transmitting the power generated by the piston to the crankshaft, the connecting rods contribute to the propulsion of the vehicle. Made from durable materials like steel or aluminum, these rods are designed to withstand the high stress and heat generated during engine operation. Their precise shape and size also impact the engine's performance, influencing factors such as horsepower and torque output.
