PURPOSE:To supply a proper quantity of fuel according to the engine operation state by installing a control means which controls the injection quantity of fuel supplied from a fuel injection valve by switching a fuel setting means for low load and a fuel setting means for high load. CONSTITUTION:A fuel setting means 17 for low load which sets the fuel injection quantity in low-load operation on the basis of the intake pressure and engine revolution speed is installed. Similarly, a fuel setting means 18 for high load is installed. A control means 19 which switches the fuel setting means 17 for low load and the fuel setting means 18 for high load according to the case of the supply of intake from the second intake passage 7 and the stop of supply and controls the fuel injection quantity supplied from a fuel injection valve 10 is installed. Thus, a proper quantity of fuel can be always supplied into a cylinder without being applied with the influence of the variation of the intake pressure due to the opening and closing of the second intake passage.
