Claims (2)

  1. 기통별로 연료분사벨브를 배설하고, 이들 연료분사밸브를 개별로 구동제어하도록 한 내연기관의 제어장치로서, 기통별로 배설되어 각기통의 실화를 검출하는 실화검출수단과, 실화가 검출된 기통의 연료분사밸브를 선택하여, 그 구동을 정지시키는 구동정지수단을 구비한 것을 특징으로 하는 내연기관의 제어장치.
  2. 기통별로 연료분사밸브를 배설하고, 엔진의 부하, 회전수등에 의거하여 연료분사량을 연산하는 동시에, 공연비센서의 출력에 의거하여 엔진의 공연비가 목표공연비로 되도록 연료분사량을 피드백 보정하여 상기 각 기통의 연료분사밸브를 개별로 구동제어하도록 한 엔진의 연료분사제어장치에 있어서, 기통마다 실화를 검출하는 실화검출센서를 배설하고, 이 실화검출센서에 의해서 실화가 검출되었을 때, 실화가 검출된 기통의 연료분사밸브의 구동을 정지시키는 동시에, 실화가 검출되어 있지 않은 다른 기통에 대해 상기 공연비센서의 출력에 의거한 피드백 보정을 제어하도록 한 것을 특징으로 하는 내연기관의 제어장치.
