Introduction
The electric fuel pump in the "Fuel pump electronic control" system is activated as and when required. The DME or
DDE control unit calculates the amount of fuel required at the given point in time. The EKP control unit controls the
electric fuel pump on the basis of mappings so that the electric fuel pump delivers the exact amount of fuel required.
[System overview ...]
In conventional systems, the electric fuel pump is operated continuously at maximum speed using the highest on-
board supply voltage available. The maximum amount of fuel that may be required is made available regardless of
the operating conditions.
The electronically controlled fuel pump system optimises the supply of fuel and reduces fuel consumption.
The electronically controlled fuel pump system is available for both petrol and diesel engines.
Note: In this case, EKP = "Electronic fuel pump control" .
The abbreviation EKP is often used to refer to the electric fuel pump itself. The electronically controlled fuel
pump system described here is controlled by a control unit called the EKP control unit. The abbreviation EKP
is used here to refer to the system as a whole.
