Abstract (en)
[origin: EP1985829A1] An automatic fuel supply adjusting device for motor vehicles comprises a driving speed sensor (SV), a driving state sensor (SS), a gas pedal sensor (9) and a control unit (8) for controlling the amount of fuel supply, the gas pedal sensor (9), the driving speed sensor (SV) and the driving state sensor (SS) being coupled with the control unit (8), wherein the operation state of the control unit (8) of the automatic fuel supply adjusting device is so controlled according to a signal detected by the gas pedal sensor (9), that the engine is supplied with fuel in the normal state or with fuel at idle speed. In the case where the gas pedal is kept in an advanced position and the engine is supplied with fuel in the normal state for so long time that the motor vehicle reaches a constant-speed state, then the control unit (8) enables to supply the engine with fuel in the normal state and with fuel at idle speed alternatively under a preset speed difference value.
