L10 MECHANICAL

For the L10 MECHANICAL engine, the shutoff valve controls the flow of fuel to the engine. Its precise fit and function ensure efficient engine start and stop, maintaining the integrity of the engine’s operation. The valve’s design allows for smooth transitions between operational states, contributing to the engine’s overall performance and longevity.

N14 MECHANICAL

In the N14 MECHANICAL engine, the shutoff valve part number 3073888 is engineered to handle the specific demands of this engine model, ensuring a quick and reliable shutoff process. Its compatibility with the N14 MECHANICAL engine is critical for maintaining engine efficiency and preventing potential issues from improper shutoff procedures.

Grouping for Efficiency

Both the L10 MECHANICAL and N14 MECHANICAL engines benefit from the use of the Cummins Shutoff Valve part number 3073888. This compatibility ensures that users can rely on a single part for multiple engine types, simplifying maintenance and inventory management.

Role of Part 3073888 Shutoff Valve in Engine Systems

The Part 3073888 Shutoff Valve is integral to the fuel management system of various engine setups. It operates in conjunction with the Fuel Valve to regulate fuel flow to the engine. When activated, it interrupts the fuel supply, effectively stopping the engine, which is crucial in emergency situations requiring immediate shutdown.

In normal operation, the Shutoff Valve remains open, allowing a consistent flow of fuel from the Fuel Valve to the engine’s combustion chambers. This ensures the engine receives the necessary fuel for combustion, maintaining efficient operation. The valve’s precise control over fuel flow also contributes to better fuel economy and reduced emissions by allowing for more accurate fuel delivery.

Additionally, the Shutoff Valve plays a role in the engine’s start-up sequence. During start-up, the valve ensures that fuel is delivered only when the engine is ready to ignite it, preventing fuel wastage and potential engine damage from unburnt fuel.

The integration of the Shutoff Valve with the Fuel Valve enhances the overall safety of the engine system. By providing a reliable means to cut off fuel supply, it reduces the risk of fuel-related fires or explosions in the event of an engine malfunction.

Conclusion

The Cummins 3073888 Shutoff Valve is a key component in the fuel management system, working in tandem with the Fuel Valve to ensure safe, efficient, and reliable engine operation. Its robust design, compatibility with various engine models, and critical role in fuel flow regulation make it an essential part for commercial trucks.
