Engine Poppet Valve Rocker Arm
Item Name Code (INC) 60983
 |
A metal item designed to pivot on a shaft, ball stud, or the like, and transmit the intermittent motion derived through linkage, from the cam lobe of a camshaft or cam ring to the poppet valve of an internal combustion engine. It may have an adjusting screw, roller, and/or bearing(s).
Additional Information for Engine Poppet Valve Rocker Arm
The engine poppet valve rocker arm is a component of an internal combustion engine. It is responsible for transmitting the motion from the camshaft to the poppet valve, allowing the valve to open and close at the appropriate times during the engine's operation.
The rocker arm is typically mounted on a rocker shaft and pivots on a fulcrum. One end of the rocker arm is in contact with the camshaft, which has lobes that push against the rocker arm to create the necessary motion. The other end of the rocker arm is in contact with the poppet valve, which is located in the cylinder head.
When the camshaft rotates, the lobes push against the rocker arm, causing it to pivot. This motion is then transferred to the poppet valve, which opens or closes depending on the engine's timing requirements. The poppet valve allows the air-fuel mixture to enter the combustion chamber and the exhaust gases to exit.
The rocker arm is an essential component in the engine's valve train system, ensuring proper valve operation and timing. It is typically made of durable materials such as steel or aluminum to withstand the high forces and temperatures within the engine. Regular maintenance and inspection of the rocker arm are important to ensure optimal engine performance and longevity.
