PURPOSE:To improve the output and fuel consumption by feedback controlling the fuel injection for every cylinder such that the exhaust gas temperature and the average gas temperature are detected for every cylinder and matched. CONSTITUTION:On the basis of the signals from exhaust gas temperature sensors 21-26 arranged on respective cylinder of internal-combustion engine 1, exhaust gas temperature operating means 3 will calculate the exhaust gas temperature for every cylinder corresponding with actual air-fuel ratio for every cylinder and the average exhaust gas temperature corresponding with the average air-fuel ratio of all cylinders then compare them through feedback correction factor setting means 4 for every cylinder and set the feedback correction factor inherent to every cylinder. Injection operating means 5 for every cylinder will multiply the average injection by said correction factor to obtain the injection for every cylinder thus to function a fuel injection valve 7 through drive pulse output means 6 with the fuel injection timing of said cylinder.
