<p>PROBLEM TO BE SOLVED: To enable the supply of stable gas fuel to an internal combustion engine just after return from a fuel stop, which is caused by removal of a stop condition, ensure the combustion stability of the internal combustion engine and improve adverse effects to the emission control of exhaust gas, the fuel economy and the operation performance.SOLUTION: A control apparatus 15 of an internal combustion engine comprises: a first intake passage 8 connected to the internal combustion engine 1, a first injection device 11 provided on the first intake passage for supplying liquid fuel to the internal combustion engine, and a fuel stop control part for stopping the supply of the liquid fuel when a stop condition of the internal combustion engine is satisfied during deceleration. The control apparatus comprises: a second injection device 13 for supplying gas fuel to the internal combustion engine; a second intake passage 12 provided with the second injection device and connected to the first intake passage; a fuel switch control part for switching between the liquid fuel and the gas fuel; and a fuel increase control part for increasing the supply amount of the gas fuel when the stop condition is removed after the supply of the gas fuel is stopped by the fuel stop control part.</p> |
