A rocker arm is a mechanical component used in internal combustion engines to transfer motion from the camshaft to the engine valves. It acts like a small lever, converting the cam’s rotating motion into the opening and closing of valves, allowing air and fuel in and exhaust gases out. Made from durable materials like steel or aluminum alloys, rocker arms are designed for strength, precision, and wear resistance. They ensure smooth engine performance, efficiency, and reliable operation under high-speed conditions.
