ENGINE IDLE REDUCTION/RESTART DEVICE AND ENGINE IDLE REDUCTION/RESTART METHOD

摘要

PROBLEM TO BE SOLVED: To suppress duplicated fuel injection for a cylinder in which unburnt fuel is present when crank reversal turn is generated in an engine restart after an idle reduction.;SOLUTION: A control part (15) has: a timer synchronized fuel injection control part (60) for specifying a cylinder to which fuel is injected initially in the establishment of an engine restart condition and setting a timer synchronized injection finished flag; a sequential fuel injection control part (90) for specifying a cylinder to which fuel is injected in succession to the initial fuel injection and setting a sequential fuel injection finished flag; and an engine start ignition control part (95) for resetting the flag for each cylinder in prescribed flag erasing timing. When one of the timer synchronized injection finished flag and the sequential injection finished flag corresponding to the specified cylinder is set, the sequential fuel injection control part determines that the specified cylinder is a cylinder in which unburnt fuel is present and suppresses the fuel injection.;COPYRIGHT: (C)2014,JPO&INPIT
