Title
(EN) CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE
(KO) 내연 엔진용 제어 장치
Abstract
(EN)
An engine ECU executes a program including the steps of: calculating a fuel injection ratio of an in-cylinder injector (S100); calculating an amount of spark advance using a first map employed when the in-cylinder injector has a fuel injection ratio of one, said first map providing a timing of ignition with a maximum amount of spark advance (S220); calculating an amount of spark advance using a second map employed for a fuel injection ratio of zero, said second map providing a timing of ignition with a minimum amount of spark advance (S230); and calculating an amount of spark advance using a third map employed for a fuel injection ratio larger than zero and smaller than one, said third map providing a timing of ignition with a larger amount of spark advance for a larger ratio (S240). ©KIPO&WIPO 2008

엔진 ECU 는 기통내 인젝터의 연료 분사 비율을 계산하는 단계 (S100), 기통내 인젝터가 1 인 연료 분사 비율을 가질 때 이용되며, 스파크 어드밴스의 최대 양으로 점화 타이밍을 제공하는 제 1 맵을 사용하여 스파크 어드밴스의 양을 계산하는 단계 (S220), 0 인 연료 분사 비율에 대해 이용되고, 스파크 어드밴스의 최소 양으로 점화 타이밍을 제공하는 제 2 맵을 사용하여 스파크 어드밴스의 양을 계산하는 단계 (S230), 및 0 보다 크고 1 보다 작은 연료 분사 비율에 대해 이용되고,더 큰 비율에 대해 스파크 어드밴스의 더 큰 양으로 점화 타이밍을 제공하는 제 3 맵을 이용하여 스파크 어드밴스량을 계산하는 단계 (S240) 를 포함하는 프로그램을 실행한다.
