Automobile fuel pump with control device adjusting DC voltage for fuel pump drive motor for controlling pump output

摘要

The fuel pump (2) has an electric drive motor and a control device which controls the output of the fuel pump by altering the DC voltage (4) for the drive motor via a DC/DC converter (8), in response to control signals (16) received from an engine control device. The control signals may be supplied to a microcontroller (14) providing setting signals (18) for the DC/DC converter.
