Cummins®

The Cummins 3006475 Throttle Shaft is a critical component in the operation of commercial trucks, designed to manage the airflow into the engine. It ensures that the engine operates efficiently and responsively to driver inputs. Throttle shafts are essential to engine management systems, acting as a bridge between the accelerator pedal and the throttle body to regulate engine speed and power output ¹.

Basic Concepts of Throttle Shafts

A throttle shaft is a mechanical component that connects the throttle body to the accelerator pedal. It translates the driver’s input from the pedal into a corresponding movement of the throttle plate within the throttle body. This movement controls the amount of air entering the engine, directly affecting engine performance. The throttle shaft interacts with both mechanical and electronic systems, including sensors that monitor its position and feed data to the engine control unit (ECU) for precise fuel injection and ignition timing ².

Purpose of the 3006475 Throttle Shaft

The Cummins 3006475 Throttle Shaft ensures that the engine responds accurately to the driver’s throttle inputs. It contributes to engine performance by allowing for fine-tuned control over the air intake, which is essential for maintaining optimal combustion. This component also aids in fuel efficiency by enabling the engine to operate at its most efficient air-fuel ratio under varying load conditions. Additionally, it enhances driver control by providing a direct and responsive link between the accelerator pedal and the throttle body ³.

Role of Part 3006475 Throttle Shaft in Engine Systems

The Throttle Shaft, identified by part number 3006475, is an integral component in the operation of engine systems, particularly in the regulation of airflow into the engine. This shaft is designed to work in conjunction with the throttle mechanism, which controls the amount of air entering the engine’s combustion chamber.

When the throttle is adjusted, either manually by the operator or automatically by the engine’s control system, the Throttle Shaft moves to open or close the throttle plate. This action directly influences the engine’s power output and operational efficiency.

In addition to its primary function, the Throttle Shaft also interacts with the Stop Shaft. The Stop Shaft serves as a limiter, preventing the throttle from opening beyond a certain point. This safety feature ensures that the engine does not receive an excessive amount of air, which could lead to over-revving and potential damage.

The coordination between the Throttle Shaft and the Stop Shaft is essential for maintaining optimal engine performance and protecting the engine from harm. This interplay ensures that the engine operates within safe parameters, delivering the necessary power while safeguarding against over-exertion ¹¹.

Conclusion

The Cummins 3006475 Throttle Shaft is a vital component in the efficient operation of commercial truck engines. Its role in managing airflow, ensuring precise control over engine performance, and contributing to fuel efficiency underscores its importance in engine management systems. Regular maintenance and proper installation are key to maximizing the benefits of this Cummins part, ensuring long-term reliability and performance.
