PROBLEM TO BE SOLVED: To provide a fuel injection valve control device accurately detecting a fuel injection valve with fuel oil consumption reduced. SOLUTION: In this fuel injection valve control device for the fuel injection valves 1 injecting fuel to the cylinders of an engine, a crank angle sensor 3 detects engine speed, an air-fuel ratio sensor 4 provided in an exhaust passage 10 detects an air-fuel ratio of exhaust gas, and a decrease in engine speed is correlated with a part where the air-fuel ratio made lean, thereby detecting the cylinder from which exhaust gas where the air-fuel ratio made lean is discharged. Then, the fuel oil consumption of the cylinder from which the exhaust gas with the air-fuel ratio made lean is discharged is learned. COPYRIGHT: (C)2010,JPO&INPIT
