If the second gas concentration is lower than or exceeds a set range, the gas supplement unit stops supplying air to the first vaporized fuel.

In summary, the present invention utilizes the first gas detecting unit and the second gas detecting unit to respectively detect the concentration of the specific gas of the first vaporized fuel or the second vaporized fuel.
