PROBLEM TO BE SOLVED: To prevent knocking, generation of misfire, and an increase in concentration of NOx in exhaust gas, even in the case a secondary fuel injection amount is changed or dispersed. SOLUTION: In this device, a secondary fuel is supplied through a fuel injection device 5, and gaseous fuel is supplied through an air intake system 2. Then, a misfire detecting means 8 checks for misfire. If the misfire is detected, the secondary fuel injection amount is increased to prevent the misfire. The increased secondary fuel injection amount is newly stored in a fuel injection amount controlling means 4 as a set fuel injection amount. |
