<P>PROBLEM TO BE SOLVED: To provide a control device of a dual-fuel engine capable of suppressing the consumption of a fuel which cannot be easily supplemented, and a control device of a hybrid vehicle having a dual-fuel engine in which the consumption of the fuel which cannot be easily supplemented is suppressed without causing torque shock. <P>SOLUTION: Hydrogen is used as the fuel while a catalyst is not activated. After the catalyst is activated, the fuel is changed to a gasoline and hydrogen by operating a switch for the operation. When the gasoline is used, a map for gasoline is used for the operation. When the hydrogen is used, a map for hydrogen is used for the rich operation and the lean operation. When the hydrogen is used by operating the switch and the residual amount of hydrogen is less, the lean operating area is so increased or the degree of leanliness is increased as to suppress the consumption of the hydrogen. In this case, the insufficient amount of the drive torque of the vehicle is compensated for by supplying a power from a battery to a motor. <P>COPYRIGHT: (C)2008,JPO&INPIT |
