Understanding the Integration of Throttle Lever (Part 3625311) in Engine Systems

The throttle lever, identified by part number 3625311, is an essential component in the modulation of engine power. Its primary function is to regulate the airflow into the engine, which directly influences the fuel mixture and, consequently, the engine’s power output.

When the throttle lever is actuated, it adjusts the position of the throttle plate within the carburetor or throttle body. This action controls the volume of air entering the engine. In carburetor-equipped engines, the throttle lever’s movement is directly linked to the carburetor’s venturi, affecting the fuel-air mixture. In fuel-injected systems, the throttle lever sends signals to the engine control unit (ECU), which then adjusts the fuel injection timing and quantity to match the airflow.

The throttle lever also interacts with the linkage system, which may include cables or rods connecting it to the accelerator pedal. This setup ensures that the driver’s input is accurately translated into engine response. Additionally, in systems with cruise control, the throttle lever is part of a feedback loop that maintains a consistent engine speed despite varying loads or gradients.

In summary, the throttle lever (part 3625311) plays a significant role in the dynamic control of engine performance, ensuring that the engine responds appropriately to driver commands while maintaining efficient operation across a range of conditions.

Conclusion

The Cummins 3625311 Throttle Lever is a critical component in the operation of commercial trucks, providing drivers with precise control over engine performance.
