FAQs

What is a rocker arm in a car? A rocker arm is a fundamental component of an internal combustion engine's valvetrain. It is a lever that pivots on a shaft or stud and is responsible for transferring the rotational motion of the camshaft into the linear motion needed to open and close the engine's intake and exhaust valves.

What are rocker arms made of? Rocker arms are manufactured from various materials chosen for strength, durability, and weight. Common materials include stamped steel for cost-effective mass production, cast iron for durability, and forged aluminum or chromoly steel for high-performance applications where reducing valvetrain mass is critical for engine efficiency.

What does a rocker arm do? The primary function of a rocker arm is to act as an intermediary lever between the camshaft and the valves. As the camshaft lobe rotates, it pushes on one end of the rocker arm, causing the other end to press down on the valve stem, opening the valve to allow air/fuel in or exhaust gases out before a spring returns it to the closed position.

What is a roller rocker arm? A roller rocker arm is an advanced type of rocker arm that features a small roller bearing at the point where it contacts the camshaft lobe. This roller design significantly reduces friction compared to a standard sliding contact rocker, leading to less wear, lower operating temperatures, the potential for increased engine rpm, and improved overall valvetrain efficiency.

How does a rocker arm work? A rocker arm works on a simple pivoting lever principle. It is mounted on a stationary shaft or stud. One end (the heel) rests on or is pushed by the camshaft lobe. As the cam lobe's high point rotates into position, it lifts that end of the rocker arm. This causes the opposite end (the toe) to press downward on the stem of the valve, opening it against the pressure of the valve spring.

What is the purpose of a rocker arm? The essential purpose of a rocker arm is to enable the camshaft, which is located in the engine block or cylinder head, to actuate the valves, which are located in the cylinder head. It translates the camshaft's profile into the precise opening and closing timing of the valves, which is absolutely critical for engine operation, air/fuel mixture intake, combustion, and exhaust expulsion.
