Abstract:
An internal combustion engine device comprising:a suction air duct for introducing combustion air into an internal combustion engine; an inside air introducing duct having an inside air suction port for taking in air from an engine compartment into which the internal combustion engine is incorporated, the inside air introducing duct introducing the thus taken inside air into the suction air duct; an outside air introducing duct having an outside air suction port for taking in outside air from the outside of the engine compartment, the outside air introducing duct introducing the thus taken outside air into the suction air duct; an inside and outside air volume adjusting means for adjusting a ratio of a volume of inside air to that of outside air, introduced into the suction air duct; a suction air volume adjusting means for adjusting a volume of all air supplied to the suction air duct; a heating means for heating the suction air volume adjusting means, the heating means being capable of variably controlling the heating; and a control means for controlling the suction air volume adjusting means and the heating means, wherein when a load of the internal combustion engine is lower than a predetermined value, the inside and outside air volume adjusting means is controlled by the control means so that the inside air, the volume of which is larger than that of the outside air, can be supplied to the internal combustion engine, and the heating means is controlled by the control means so that the suction air volume adjusting means can be heated.
