PROBLEM TO BE SOLVED: To provide a fuel injection control device capable of suppressing occurrence of combustion failure caused by replenishment of fuel having fuel properties different from stored fuel in start of fuel injection with the usage of the replenished fuel.SOLUTION: In a fuel injection control device, a learning value KG which compensates steady deviation between an actual air-fuel ratio and a target air-fuel ratio is updated through air-fuel ratio feed back control during operation of an engine, and a fuel injection amount is corrected with the usage of the learning value KG. When replenishment of fuel is detected in starting of the engine, a correction amount C is added to the learning value KG. When the learning value KG is included in a prescribed range L, the correction amount C is made to be 0 (zero), and the learning value KG is used as it is to start the engine. When the learning value KG is not included in the prescribed range L, the learning value KG is corrected to be a value equivalent to boundary values KGb1, KGb2 of the prescribed range L by the correction value C, and the engine is started. |
