Claims (2)
- 전자 구동되는 인젝터와, 상기 인젝터에 제 1통전시간과 제 2통전시간을 갖는 구동신호를 출력하는 분사 제어수단과,상기 제 1통전시간에는 상기 인젝터를 밸브 개방시키는 대전류를 통전하며, 상기 제 2통전시간에는 상기 인젝터를 밸브 개방상태로 유지하는 소전류를 통전하는 인젝터 구동수단을 구비하며,상기 제 1통전시간이, 통전 시작부터 상기 인젝터의 전체 개방에 이를 때까지의 밸브 개방 소요시간 보다 짧은 시간으로 설정되고, 이 시간차가 상기 제 1통전시간에서 전류가 차단된 때, 이 전류 차단부터 상기 인젝터가 밸브 폐쇄 동작을 시작할 때까지의 밸브 폐쇄동작 지연시간보다 짧은 값으로 설정된 것을 특징으로 하는 연료 분사 시스템.
- 제 1항에 있어서,제 1통전시간과 제 2통정시간과의 사이에 통전을 휴지하는 통전 휴지시간이 설정되며, 이 통전 휴지시간이, 제 1통전시간의 전류 차단 후에 밸브가 폐쇄 될 때까지의 제 1밸브 폐쇄 소요시간과, 제 2통전시간의 전류 차단 후에 밸브가 폐쇄될 때까지의 제 2밸브 폐쇄 소요시간과의 시간차와 거의 동등하게 설정된 것을 특징으로 하는 연료 분사 시스템.
