A Rocker Arm in an engine is a lever mechanism that converts the rotational motion of the camshaft into linear motion to open and close the valves. It distributes the force from the camshaft to the valve stem, ensuring smooth valve operation and proper sealing. Made from durable materials, the rocker's arm requires regular maintenance to ensure optimal performance. Its role is critical in the valvetrain system, contributing to the engine's overall functionality and performance.Attributes:• Provides strength and heat resistance.• Lever mechanism for opening and closing valves.• Load distribution across the valve stem.• Contribution to overall engine performance and functionality.Application:A Rocker Arm in an engine helps in opening and closing the valves, facilitating the intake of air and fuel and the expulsion of exhaust gases during the combustion process.
