Rail Pressure Control Digital Diesel Electronics (DDE 7.3) In The M57TU2TOPPING US: Notes

The following components belong to the common rail system and influence the rail pressure control, the principle of which is identical to the ECE version of the M57TU2TOPPING engine both with regard to structure and function. This entire high-pressure system is able to build up and maintain fuel pressures of up to 1800 bar:

• High-pressure pump (HDP)
• Rail Pressure Control Valve (DRV)
• Flow regulating valve (MRV)
• Rail pressure sensor
• High-pressure accumulator (fuel rail)
• High-pressure lines
• All six Piezo injectors
