摘要:The invention relates to a circuit arrangement and method for controlling anelectric fuel pump in a non-return fuel delivery system that comprises an electric fuelpump (1) arranged in a fuel tank (2) for delivering fuel from the fuel tank to a first fuelline (3) to a high-pressure pump (4) that is linked with fuel injection valves (7) via a secondfuel line (5). The circuit arrangement further comprises a motor control (9) that controlsthe pump capacity of the electric fuel pump (1) and a control circuit (11) that is preferablyintegrated in the motor control (9) and that determines the required pump capacity ofthe electric fuel pump (1) and outputs a control signal to the motor control (9) thatcorresponds to the required pump capacity determined. The circuit arrangement isspecifically characterized in that the control circuit (11) is provided with a temperaturemodel circuit (18) for determining the highest temperature (Tmax) present in the fueldelivery system, thereby controlling the required pump capacity of the electric fuelpump (1) in accordance with the highest temperature present in the fuel delivery system
that was determined.
