Patent ID: 7567866

Claim:
A fuel injection control device of a internal combustion engine that is adapted to use multiple kinds of fuel, the control device comprising: a starting completion detection means adapted to detect a starting state of an internal combustion engine, and adapted to determine a fuel injection quantity in response to a state of the internal combustion engine after detecting the completion of starting by the starting completion detection means, wherein the control device stores a plurality of reference fuel injection quantity maps corresponding to a mixed concentration of the multiple kinds of fuel, and also stores which map out of the plurality of reference fuel injection quantity maps is used, and wherein a start control of the internal combustion engine is performed by the control device based on stored data of the reference fuel injection quantity map which is used immediately before previous stopping at a time of initiating of starting, and at the same time, the start control is performed by gradually increasing a fuel injection quantity until the starting of the internal combustion engine is completed.
