Cummins®

The Cummins 3013300 Rocker Lever is a component designed for use in heavy-duty truck engines. It plays a significant role in the operation of these engines by facilitating the transfer of motion from the camshaft to the valves. This transfer is vital for the engine’s ability to intake air and expel exhaust gases, which are fundamental processes for engine function and performance.

Basic Concepts of Rocker Levers

A rocker lever, in the context of an engine system, is a mechanical component that amplifies and redirects the motion it receives. Typically, it converts the rotational motion of the camshaft into the linear motion needed to open and close the engine’s valves. This conversion is achieved through a pivot point, allowing the lever to rock back and forth, hence its name. The efficiency and precision of this motion transfer are crucial for the engine’s overall performance and efficiency ¹.

Purpose of the 3013300 Rocker Lever

The 3013300 Rocker Lever plays a role in the operation of a truck engine by connecting the camshaft’s motion to the valves. It ensures that the valves open and close at the correct times and with the appropriate force. This interaction is critical for maintaining the engine’s combustion process, affecting both the engine’s power output and its fuel efficiency. The rocker lever works in conjunction with pushrods, camshafts, and valve springs, forming a coordinated system that regulates the engine’s air and fuel mixture ².
