OEM Bosch 281006019 Fuel Rail Pressure Regulator Relief Valve

The high-pressure rail gives its name to the common-rail system and binds the fuel injection pump and the fuel injectors together as the central hydraulic component. The Common Rail system stores the high-pressure fuel and supplies this to the eight fuel injectors as needed. A fuel rail pressure sensor and fuel rail pressure relief valve are independent parts of the common rail fuel injection system design. The 6.6L Duramax diesel engine uses a Bosch Fuel pressure regulator, pressure control valve, or pressure limiting valve located at the end of the high-pressure common rail.

The Bosch Diesel Fuel Injection Pump Pressure Relief Valve is one of the major components of the high-pressure common rail. The RPS Sensor or rail pressure sensor is installed on the high-pressure pump to constantly monitor the fuel injection pump's output pressure. The rail pressure sensor transmits this data back to the engine control module or ECM to optimize engine performance. The rail sensor communicates the pressure values that serve to regulate the system pressure and control the injectors. The pressure control valve sets the fuel injection system pressure supplied to the common rail injection system. The pressure regulator or limiting valve will reduce the common rail pressure in case of overload to protect the fuel injection system components injection from damage.

• FAQ: Bosch 0281006019 fuel rail pressure sensor monitors the fuel rail pressure generated by your fuel injection pump. The data acquired by the 6.6L Duramax Bosch Fuel Pressure Relief Valve controls the rail pressure by varying the volume of fuel delivered by the high-pressure pump. When excess fuel rail pressure is determined, the 6.6L Duramax Bosch Fuel Pressure Relief Valve removes the excess pressure from the fuel rail and allows this to return to the fuel return system.
