The VP 30 is modularly constructed. The fuel supply system is completely electronically
controlled.
The following requirements are optimally satisfied by the use of the VP 30
low emissions of pollutants
high economicalness
high driving comfort
The VP 30 is an axial piston distribution injection pump which is controlled by a high-
pressure solenoid valve. It has fully electronic control of the fuel quantity and the injection
timing.
A pump high pressure of up to 900 bar is created in the VP 30, which produces high
atomisation energy at the nozzle and a fast response to the fuel quantity regulation by fast
switching of the high pressure solenoid valve.
The pump control unit is mounted on the top of the injection pump. It uses information from
the rotational angle sensor and from the PCM to calculate the control signals for the high
pressure solenoid valve and the start of injection timing.
NOTE: Before the electrical plug connection of the pump control unit is disturbed, make
absolutely certain that no electrostatic charge is present. An electric discharge may lead
to a fault in the control unit.
The fuel system cannot be driven dry while the vehicle is driving. When there is only a
certain amount of fuel remaining, a signal from the sender in the tank causes the PCM to
make the engine judder.
