Document Type and Number:
Japanese Patent JPH0531655
Kind Code:
B2
Abstract:
PURPOSE:To directly find fundamental injection timing from an engine condition, by installing a process, which finds controlling engine speed and controlling accelerator opening after idling speed controlling compensation, and another process finding the fundamental injection timing. CONSTITUTION:Fundamental injection timing Tbase being suitable for engine conditions inclusive of at least and engine speed NE and the actual accelerator opening Acco is found, and on the basis of this fundamental injection timing Tbase, the injection timing is controlled. According to at least the actual engine speed NE and the actual accelerator opening Accp, there is provided with a process finding the fundamental injection timing Tbase from controlling engine speed NEisc and controlling acceletator opening AccpA after idling speed controlling ISC compensation. Likewise, there is provided with a process finding the fundamental injection timing from the controlling engine speed and the controlling accelerator opening. Thus, the fundamental injection timing is directly findable from these engine conditions.
