<P>PROBLEM TO BE SOLVED: To reduce Raw NOx at engine start-up and prevent a reduction in power charged in a battery at a high level, in a hybrid vehicle with an engine to which the gaseous fuel is supplied. <P>SOLUTION: The device includes an engine 6 to which gaseous fuel is supplied, a generator 7 driven by the engine 6 to generate power, a battery 9 storing generated power in the generator 7, a motor 4 to be driven by electric power received from at least one of the battery 9 and the generator 7. When power charged in the battery 9 is a predetermined value or more, a fuel injection ratio during intake stroke is set to be more than a fuel injection ratio during intake stroke in a second fuel injection mode. When the amount of charged power is less than a predetermined value, a fuel injection ratio in the first injection mode is reduced to increase a fuel injection ratio in the second fuel injection mode as compared with the case where the amount of charged power is a predetermined value or more. <P>COPYRIGHT: (C)2013,JPO&INPIT |
