[1989년 특허출원 제701578호] 내연기관에서의 공회전 및 감속 도중에 공기를 비례조정하기 위한 방법 및 장치가 제공된다. 여기서, 공회전 도중에, 내연 기관은 PI 콘트롤러(203,204)에 의해 정상 속도로 조절된다. 동시에, 소요 공기량(60)이 측정되어 스토어(304)에 저장된다. 감속 도중에, 내연 기관의 공기량 처리량은 상기 막 저장된 값으로 조절된다. 또한, 콘트롤은 특정 작동 모드의 함수로서 제어를 행하는 일련의 변수를 수용한다. PCT No. PCT/DE88/00745 Sec. 371 Date Aug. 10, 1989 Sec. 102(e) Date Aug. 10, 1989 PCT Filed Nov. 23, 1988 PCT Pub. No. WO89/05905 PCT Pub. Date Jun. 29, 1989.A process and a device for air proportioning during idling or overrun mode of operation in an internal-combustion engine are provided. During idling, the internal-combustion engine is regulated to a nominal speed by means of a PI controller (203, 204) and a preliminary air rate control value is determined as a function of temperature, gear position and air-conditioning state of the vehicle. At the same time, the actual air mass or air intake rate (60) is measured and the difference value of the actual air intake rate and the preliminary air-rate control value is stored in a store (304). During overrun, the air-mass throughput of the internal-combustion engine is regulated to this stored value. Furthermore, the control receives a series of auxiliary variables which make it easier to carry out the control as a function of the particular operating mode.
