Abstract
When a load given to the engine 100 is less than a predetermined value, the outside air suction port 104 is closed and only inside air is supplied to the engine 100, and the valve 112a is opened so as to supply warm water to the heater 112. When the load given to the engine 100 is not less than the predetermined value and the temperature of air outside the engine compartment 11 is lower than a predetermined value, the inside air suction port 102 is closed and only outside air is supplied to the engine 100, and the valve 112a is closed so that the supply of warm water to the heater 112 is stopped.
Claims11
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.
