Compatibility with Cummins Engines

The Cummins part number 3076343, a Fuel Shutoff Valve, is designed to be compatible with several specific engine models, including the K38, K50, and N14 MECHANICAL engines. This valve is integral to the engine’s operation, ensuring that fuel supply is controlled effectively ¹.

Role of the Cummins 3076343 Fuel Shutoff Valve in Engine Systems

The Cummins 3076343 Fuel Shutoff Valve is an integral component in the orchestration of engine systems, ensuring the precise control of fuel flow. This valve operates in conjunction with the fuel valve to manage the delivery of fuel to the engine. When the engine is operational, the valve remains open, allowing a steady stream of fuel to pass through the fuel valve and into the combustion chamber.

In scenarios where the engine needs to be shut down—either as part of normal operation or in an emergency—the valve closes, effectively halting the fuel supply. This action is vital for preventing fuel wastage and ensuring safety by stopping the combustion process.

Additionally, the valve interacts with the engine’s control system, which monitors various parameters such as engine temperature, pressure, and operational status. Based on these inputs, the control system signals the valve to open or close, maintaining optimal engine performance and efficiency ².

Conclusion

The Cummins 3076343 Fuel Shutoff Valve plays a significant role in the efficient and safe operation of commercial truck engines. Its precise control of fuel flow, robust design, and integration with engine systems make it a vital component for maintaining engine performance, safety, and environmental compliance.
