PURPOSE:To make it possible to satisfactorily distribute fuel among a plurality of engine cylinders, by supplying fuel from only a fuel injection valve upstream of a throttle valve when the temperature of an engine is below a predetermined temperature. CONSTITUTION:In an internal combustion engine 1 comprising a plurality of engine cylinders, an fuel injection valve 6 and an auxiliary fuel injection 6a are disposed respectively upstream and downstream of a throttle valve 3', and an ECU 5 control the supply of fuel. In this arrangement, when the temperature of an engine detected by an engine cooling water temperature sensor 9 is below a predetermined value, fuel is fed from the fuel injection valve 6. Meanwhile, when the temperature of the engine exceeds the predetermined value and the opening degree of the throttle valve detected by a throttle valve opening degree sensor 4 is below a predetermined opening degree, fuel is fed from the auxiliary fuel injection valve 6a. With this arrangement, even though the temperature of the engine is low, it is possible to satisfactorily distributes fuel among engine cylinders, and further, it is possible to a eliminate the necessity of changeover from the auxiliary fuel injection valve 6a to the fuel injection valve 6, thereby it is possible to prevent variations in the supply amount of fuel which are liable to occur upon changeover between the values 6, 6a.
