• Injection pressure and injection timing selectable within wide limits and independent of engine operating point
• Reduced black smoke formation due to high injection pressures of up to 1350 bar
• Reduced noise and emissions due to preliminary injection
• High pressure generated by radial piston pump
• Pressure control by pressure control valve
• Continuous measurement of pressure by sensor in distributor strip, closed control circuit
• Injector with electromagnetic 2/2 solenoid valve
Low pressure delivery
The advance delivery pump supplies the high pressure pump with fuel via the in-line EFP and the fuel filter.
High pressure delivery
The high pressure pump compresses the fuel to system pressures of up to 1350 bar. The compressed fuel is then routed into a pipe-like fuel high pressure accumulator (rail) via a pressure control valve and a high pressure line.
