The Pressure Regulator Valve, identified by part number 3395465, is a critical component in the fuel system of various Cummins engines. This part is designed to maintain optimal fuel pressure within the engine’s fuel system, ensuring efficient engine performance and longevity.

B5.9 GAS PLUS CM556

The B5.9 GAS PLUS CM556 engine benefits from the precise regulation of fuel pressure provided by the 3395465 Pressure Regulator Valve. This valve ensures that the engine receives the correct fuel pressure, which is essential for maintaining the balance between performance and fuel efficiency.

G5.9 and G8.3

For the G5.9 and G8.3 engines, the 3395465 Pressure Regulator Valve plays a pivotal role in managing the fuel system’s pressure. These engines, known for their robust performance, rely on this component to deliver consistent and reliable fuel pressure, which is crucial for their operation.

G855

The G855 engine also integrates the 3395465 Pressure Regulator Valve into its fuel system. This valve is essential for maintaining the precise fuel pressure required by the G855 engine, ensuring that it operates at peak efficiency and reliability.

Role in Engine Systems

In the orchestration of engine systems, the 3395465 Pressure Regulator Valve assumes a significant role by ensuring the precise regulation of fuel pressure. This component is integral to the module, where it works in concert with the fuel control system to maintain optimal fuel delivery conditions.

The Pressure Regulator Valve is positioned downstream of the fuel pump within the fuel control module. Its primary function is to modulate the pressure of the fuel that is delivered to the engine’s fuel injectors. By doing so, it ensures that the fuel injectors receive a consistent fuel pressure, which is essential for the injectors to atomize the fuel properly and deliver it into the combustion chamber in a fine mist. This atomization is vital for efficient combustion and engine performance.

Moreover, the Pressure Regulator Valve interacts with the main valve within the system. This interaction allows for the fine-tuning of fuel pressure in response to varying engine loads and operating conditions. The valve adjusts the pressure by redirecting excess fuel back to the fuel tank, thus preventing over-pressurization and ensuring that the fuel system operates within its designed parameters.

Conclusion

In summary, the Cummins 3395465 Pressure Regulator Valve is a vital component for the B5.9 GAS PLUS CM556, G5.9, G8.3, and G855 engines, ensuring that each engine maintains the correct fuel pressure for optimal performance. Its role in engine systems is crucial for maintaining efficient fuel delivery and ensuring the overall reliability and performance of Cummins engines.
