To prevent the injection volume of main fuel from becoming insufficient, and stably inject the main fuel even when an injection volume of reformed fuel increases.
An internal combustion engine 10 includes a fuel reforming catalyst 28 which generates combustible gas from a reformed fuel. During an operation of the engine, the control device injects a fuel supplied by a fuel pump 46 from a main fuel injection valve 18 toward a combustion chamber, and injects toward fuel reforming catalyst 28 from a reformed fuel injection valve 34. Consequently, a combustible gas generated from the catalyst 28 is refluxed to an air intake system together with an exhaust gas. Further, an ECU 50 corrects a target injection volume of the main fuel according to an amount of pressure drop of the fuel which is caused by an injection of the reformed fuel. Thus, the injection volume of the main fuel can be controlled with high accuracy, even when the pressure of the fuel drops transiently by a large volume of the reformed fuel being injected.
