Abstract

연료가 펌프로부터 고압부로 공급되고, 개개의 실린더로의 연료량의 조절이 솔레노이드 밸브에 의해서 제어 가능한 내연기관의 제어를 위한 방법 및 장치에 있어서, 가능한 한 신속하게 차단하는, 안전을 위한 차단기구를 제공하는 것이다.A method and apparatus for controlling an internal combustion engine in which fuel is supplied from a pump to a high pressure section and control of the amount of fuel to an individual cylinder is controllable by a solenoid valve, which provides a safety shut-off mechanism that cuts off as soon as possible. It is.

연료의 조절량이 토오크에 기여하지 않는 각도 영역에서, 연료의 조절수단에 의해 에러가 해결된다.In the angular region where the adjustment amount of the fuel does not contribute to the torque, the error is solved by the adjustment means of the fuel.
