VERFAHREN UND VORRICHTUNG ZUR UEBERWACHUNG EINER BRENNKRAFTMASCHINE

摘要

This specification discloses an internal combustion engine control system which meets two conflicting performance requirements in the automotive internal combustion engine. In the control system according to this invention, the operation of the throttle valve is controlled such that the opening angle of the throttle valve of an internal combustion engine changes according to the travel amount of the accelerator pedal in the range from the minimum value to a predetermined value less than the maximum value of the accelerator pedal travel amount of the automobile, and that the throttle valve becomes full open in the range from the predetermined value to the maximum value of the accelerator pedal travel amount. The air-fuel ratio is controlled such that an air-fuel mixture of a first air-fuel ratio is supplied in the range from the minimum value to the predetermined value of the accelerator pedal travel amount, and an air-fuel mixture of a second air-fuel ratio is supplied in the range from the predetermined value to the maximum value of the accelerator pedal travel amount.
