Throttle Shaft (Part 3046951) Compatibility with Cummins Engines

The Cummins Throttle Shaft, part number 3046951, is a critical component that ensures the smooth and precise control of engine throttle. This part is designed to fit seamlessly with several Cummins engine models, providing reliable performance across various applications.

N14 CELECT and N14 CELECT PLUS Engines

The N14 CELECT and N14 CELECT PLUS engines are part of Cummins’ advanced electronic engine control systems. The throttle shaft in these engines is engineered to interface with the electronic control module (ECM), ensuring that the throttle position is accurately reported and managed. This compatibility is crucial for maintaining optimal engine performance and fuel efficiency ¹.

N14 MECHANICAL Engine

The N14 MECHANICAL engine, which relies on mechanical linkages rather than electronic controls, also utilizes the 3046951 throttle shaft. This part is designed to work with the mechanical linkage system, providing a robust and dependable connection between the throttle pedal and the engine’s throttle body. The mechanical design ensures that the throttle response is direct and responsive, which is essential for the engine’s performance ¹.

NH/NT 855 Engines

The NH/NT 855 engines, known for their durability and power, also incorporate the 3046951 throttle shaft. This part is designed to fit the specific requirements of these engines, ensuring that the throttle control is precise and reliable. The compatibility with the NH/NT 855 engines is particularly important for applications that demand consistent and high-performance engine operation ¹.

Role of Part 3046951 Throttle Shaft in Engine Systems

The Throttle Shaft, identified by part number 3046951, is an integral component in the operation of engine systems. It is responsible for regulating the airflow into the engine, which directly influences the power output and efficiency of the engine ¹.

Interaction with the Oil Pan

The Throttle Shaft operates independently of the oil pan; however, the smooth operation of the Throttle Shaft is essential for the overall performance of the engine, which in turn affects the lubrication system managed by the oil pan. The oil pan collects and stores engine oil, which is pumped throughout the engine to lubricate moving parts, including the Throttle Shaft. Proper lubrication ensures that the Throttle Shaft moves smoothly, reducing wear and tear and enhancing the longevity of the component ³.

Influence on Engine Performance

As the Throttle Shaft regulates the airflow, it works in conjunction with other components such as the carburetor or fuel injection system to maintain the correct air-fuel mixture. This mixture is vital for efficient combustion, which powers the engine. The Throttle Shaft’s precise control over airflow ensures that the engine operates within optimal parameters, contributing to fuel efficiency and power delivery ¹.

Integration with Other Systems

The Throttle Shaft is also connected to the throttle body, which houses the butterfly valve. When the driver presses the accelerator pedal, a linkage or cable connected to the Throttle Shaft opens the butterfly valve, allowing more air into the engine. This action is synchronized with the fuel delivery system to maintain the correct air-fuel ratio ².

Conclusion

In summary, the Throttle Shaft (part 3046951) plays a significant role in modulating airflow, which is essential for the efficient operation of the engine. Its smooth functioning is supported by the lubrication system, managed by the oil pan, ensuring that all moving parts operate with minimal friction and maximum efficiency ³.
