• The rocker arm is an integral part of the engine's valve drive system, located above the engine and connected to the valve stem and valve.
• The rocker arm carries the pressure of the valve spring and transmits it to the valve for control.
• The rocker arm has sufficient strength and rigidity to withstand valve movement and valve spring force at high speed.
• Rocker arms are usually made of cast iron or cast aluminum alloy to provide sufficient strength.
• The rocker arm usually has a CAM contact surface, which controls the opening and closing time of the valve through the rotation of the camshaft.
