Claims (4)
- 엔진의 메인통로를 통과하는 공기량에 대응하여 내연기관에 공급해야 할 연료량을 결정하고, 상기 메인통로에 대하여 설치된 바이패스통로를 통과하는 흡입공기량을 제어하는 자동차용 내연기관의 제어방법에 있어서, 엔진운전상태에 대해서 공연비가 미리 정해진 값이 되도록 상기 바이패스통로를 통과하는 흡입공기량을 제어하는 스텝을 갖는 것을 특징으로 하는 자동차용 내연기관의 공연비 제어방법.
- 제1항에 있어서, 상기 바이패스통로의 공기량이 증가하는 것에 대응해서 메인통로의 공기량이 감소되고, 그 감소에 따라서 감소되는 연료공급량을 증량 보정하는 스뎁을 갖는 것을 특징으로 하는 자동차용 내연기관의 공연비 제어방법.
- 제2항에 있어서, 상기 바이패스통로를 통과하는 흡입공기량을 상기 메인통로를 통과하는 공기량과 내연기관의 속도에 대응해서 기억되어 있는 루크업테이블에서 독해하므로써 얻는 것을 특징으로 하는 자동차용 내연기관의 공연비 제어방법.
- 제1항에 있어서, 상기 공연비의 파라미터가 스로틀 개폐도, 흡입공기량 또는 연료분사펄스폭인 것을 특징으로 하는 자동차용 내연기관의 공연비 제어방법.
