Title:
FUEL INJECTION CONTROL DEVICE FOR ENGINE
Document Type and Number:
Japanese Patent JP2015102024
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel injection control device for an engine, in which the fuel injection ratio of an injector disposed at each intake port and each surge tank is controlled on the basis of an engine load and a cooling water temperature thereby to reduce the harmful exhaust gas that is due to a high mileage and a combustion promotion.SOLUTION: A fuel injection control device for an engine comprises an intake port 19, a surge tank 15, an intake port injector 23, a surge tank injector 29, and a control device 61 for controlling the fuel injection sharing ratios of the intake port injector 23 and the surge tank injector 29 on the basis of an engine load and a cooling water temperature. Said control device 61 is characterized by increasing the injection ratio of the intake port injector 23 more for the higher cooling water temperature, and for the higher engine load.
