<p><P>PROBLEM TO BE SOLVED: To improve exhaust emission in a bifuel engine. <P>SOLUTION: A device for control of an internal combustion engine has gas fuel supply units (310, 320, and 330) for supplying gas fuel, and liquid fuel supply units (410, 420, and 430) for supplying liquid fuel. The control device includes: catalyst deterioration degree detectors (124 and 125) for detecting deterioration degree of a catalyst (123) installed on an exhaust route of the internal combustion engine; and a fuel ratio determination unit (100) for determining each supply ratio between the gas fuel supplied by the gas fuel supply unit and the liquid fuel supplied by the liquid fuel supply unit, on the basis of the deterioration degree of the catalyst which is detected by the catalyst deterioration degree detector. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
