<P>PROBLEM TO BE SOLVED: To make both compatible in a well-balanced state in protecting a nozzle port part of a fuel injection valve from corrosion when stopping an internal combustion engine and preventing exhaust emission and fuel efficiency from being deteriorated by operation of the fuel injection valve for such the protection, when applying a fuel injection control device of the internal combustion engine to a vehicle having the function of automatically stopping the internal combustion engine when starting a vehicle system. <P>SOLUTION: This fuel injection control device includes the fuel injection valve 12 for injecting fuel into the internal combustion engine 10 mounted on the vehicle having the idle reduction function. After stopping fuel injection for generating torque when stopping an engine, a small quantity of fuel injection is performed so that the fuel sticks to the nozzle port part (an inner wall surface of a nozzle port 12e and a wall surface of a sac 12d) of the fuel injection valve 12. When stopping by an idle reduction, only when a probability of performing operation for turning off an IG switch 44 after stopping the engine by the idle reduction is a predetermined value or more, the small quantity of fuel injection is performed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
