A rocker arm is an essential component of the engine's valve train system in a car. It plays a vital role in the operation of the valves. The rocker arm is a lever that sits between the camshaft and the valves. When the camshaft rotates, it pushes against the rocker arm, which then pivots on a shaft to open and close the valves. This mechanical action allows the intake and exhaust valves to open and close at the proper times, ensuring precise air-fuel mixture intake and exhaust gas expulsion.

Additionally, the rocker arm serves as a force magnifier in the valve train system. The camshaft exerts a small amount of force on the rocker arm, and the rocker arm multiplies this force to open and close the valves with sufficient power. It transfers the motion from the rotating camshaft to the linear motion required for the valve operation. The proper functioning of rocker arms is crucial for maintaining engine performance, as any issues with them can lead to inefficient airflow, loss of power, or engine misfires.
