With a history spanning over a century, Cummins has established a reputation for quality and innovation in the commercial truck industry. The company’s commitment to excellence is reflected in its products, including the Cummins 3035346 Shutoff Valve.

Compatibility with Various Engines

The Cummins Shutoff Valve 3035346 is engineered to fit seamlessly with a range of Cummins engines, providing reliable shutoff functionality. It is compatible with K19 and L10 MECHANICAL engines, M11 CELECT PLUS and M11 MECHANICAL engines, N14 MECHANICAL engines, and NH/NT 855 engines. This compatibility ensures that these engines can be safely and efficiently shut down, contributing to their overall reliability and performance.

Role in Engine Systems

The 3035346 Shutoff Valve is an integral component within various engine systems, ensuring precise control over fuel flow. It operates in conjunction with several other components to maintain efficient and safe engine performance.

Integration with Fuel Systems

In fuel systems, the 3035346 Shutoff Valve works alongside the Fuel Shutoff Valve and the Fuel Shut-Off Valve Arrangement. Its primary function is to regulate the flow of fuel to the engine, allowing for smooth starts and stops. When the engine is turned off, this valve shuts off the fuel supply, preventing any residual fuel from entering the combustion chamber, which enhances safety and reduces the risk of fuel leaks.

Interaction with Solenoid Components

The Shutoff Valve is often paired with solenoid components such as the FP Solenoid Valve and the Solenoid. These solenoids are electrically controlled and are responsible for actuating the Shutoff Valve. The solenoid receives signals from the engine control unit (ECU) to open or close the valve, ensuring that fuel delivery is synchronized with engine operation. This precise control is essential for maintaining optimal fuel efficiency and reducing emissions.

Coordination with Fuel Valves and Mountings

The 3035346 Shutoff Valve also interacts with the Fuel Valve and the Fuel Valve MTG (Mounting). The Fuel Valve controls the overall flow of fuel into the system, while the Fuel Valve MTG ensures secure and stable installation of the valve. The Shutoff Valve complements these components by providing an additional layer of control, allowing for fine-tuning of fuel delivery based on engine demand.

Role in On-Board Spares Kit

In the Kit On-Board Spares, the 3035346 Shutoff Valve is a vital component. This kit is designed to provide essential spare parts for in-field repairs, ensuring that the engine can be quickly restored to operation in case of a failure. The inclusion of the Shutoff Valve in this kit underscores its importance in maintaining engine reliability and uptime.

Enhanced Engine Management

By integrating with the EBM (Engine Management System), the 3035346 Shutoff Valve contributes to enhanced engine management. The EBM relies on real-time data to optimize fuel delivery, and the Shutoff Valve plays a key role in executing these commands. This results in improved engine performance, better fuel economy, and reduced environmental impact.

Conclusion

The Cummins 3035346 Shutoff Valve is a fundamental component in modern engine systems, working in harmony with various fuel and solenoid components to ensure efficient, safe, and reliable engine operation. Its robust design, compatibility with a wide range of engines, and integration with fuel systems and engine management systems make it an essential part of Cummins’ commitment to quality and innovation in the commercial truck industry.
