The air that has flowed into the tank body 1a circulates in the tank while being in contact with the radiant energy generator, and during that time, oxygen molecules and water molecules in the air absorb the radiant energy, resulting in a so-called dissociated state. , Become excited or ionized. The activated air is taken out from the air outlet 1d and supplied to a combustion apparatus such as a boiler. The air in which oxygen and water molecules are in an ionized state or a dissociated state by the activation treatment has so-called reactivity, and the combustion oxidation reaction is promoted to increase the calorific value and the like.

There was a problem that it was difficult to raise.
According to the second example of the air filter cleaner 2 of the internal combustion engine described above, the filter 2b becomes very dirty during long-time use, and the clogging phenomenon of the filter 2b is also caused. Combustion air does not flow to the internal combustion engine. Therefore, it is necessary to replace the filter 2b and the entire air filtration cleaner 2, and there is a problem that the cost and reassembly man-hours increase. In addition, when severe clogging is left, the filter 2b is deformed by the negative pressure generated in the intake stroke of the cylinder, and dirt accumulated in the filter 2b is mixed into the combustion chamber (not shown) of the internal combustion engine.

Embodiments of an air filtration cleaner for an internal combustion engine according to the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 shows an example of an internal combustion engine, in particular, a fuel-injection gasoline internal combustion engine and its accessory device. An air filter cleaner A according to the present invention is arranged in an intake pipe, that is, an intake air flow path 7. The form of is shown.

A gasoline internal combustion engine 6 as an internal combustion engine is arranged in an intake air circulation path 7 as an intake pipe arranged in an intake system, an air filter cleaner A arranged in the intake air circulation path 7, and an exhaust system. When the intake air P is sent from the intake air flow path 7 to the combustion chamber 6a of the gasoline internal combustion engine 6 to the combustion chamber 6a, the intake valve 9 for controlling the intake air P is discharged. An exhaust valve 10 for controlling the amount of exhaust gas to be produced, a fuel injection valve 11 provided in the gasoline internal combustion engine 6, a piston 13 driven in a crankcase 12 integrated with the combustion chamber 6a, and the exhaust pipe 8 to the O ₂ sensor 14 provided, the O ₂ fuel control device for controlling the injection amount of fuel to be fed Note into the combustion chamber 6a by an electric signal proportional to the oxygen concentration including the exhaust gas from the sensor 14 15 And each. Further, during operation of the gasoline internal combustion engine 6, blow-by gas 12a flows into the combustion chamber 6a. The blow-by gas 12a is made of hydrogen (H ₂ ), hydrocarbon (HC), a mixed gas or a smoke gas subjected to partial oxidation, or the like.

The casing 16 is connected to the blow-by gas discharge port 12b of the crankcase 12 via the first connecting pipe 17 and the intake port via the ventilation valve 7a provided in the intake air circulation path 7. And a gas supply port 16b connected to the second connecting pipe 18 communicating with 7b.
The casing 16 contains a mixed liquid of water and a hydroxyl compound, and further includes a circulation inlet 16c and a circulation outlet 16d, and the mixture liquid is circulated by a circulation pump 16e. An oil filter 19 for supplementing oil mist in the blowby gas 12 a is provided in the first connection pipe 17. The gasoline vapor generated from the fuel tank 20 contains hydrocarbons (HC) and pollutes the atmosphere. In order to effectively use this as a part of the fuel, the fuel vapor is fed via the third connecting pipe 21. The tank 20 and the 2nd connection pipe 18 are connected.
In the figure, reference numeral 22 denotes a carbon canister.

The blow-by gas 12a leaked into the crankcase 12 during operation of the gasoline internal combustion engine 6 as an internal combustion engine and the gasoline vapor in the fuel tank 20 are pumped to a gas tube (not shown) via the blow-by gas intake port 16a. Is done. Since the circulation pump 16e is driven at the same time as the ignition switch is turned on, the liquid mixture is fed to the liquid tube (not shown) at a predetermined pressure. When a liquid mixture containing a hydroxyl group is ejected from a liquid tube nozzle (not shown) in a reaction zone (not shown) direction at a high pressure, a large amount of oxygen is generated. At this time, when ganlin vapor (CH ₃ ) and hydrogen (H ₂ ) are ejected from an ejection nozzle (not shown), hydrogen atoms are separated from CH ₃ to form CH ₂ , and H and CH ₂ are mixed into the liquid mixture. Mixed. This mixed liquid is ejected from the liquid tube into the mixed liquid at a predetermined pressure via the circulation pump 16e. As a result, a large amount of oxygen ions (O ₂ ) and CHO are generated from the nozzle of the liquid tube. Since the mixing chamber is heated by the blow-by gas 12a, extremely small water vapor (H ₂ O) is also generated. Oxygen molecules generated from the liquid tube trap hydrogen in the reaction zone to generate OH ions. Oxygen ions, OH ions, hydrogen ions, and hydrocarbons flow out from the overflow opening (not shown) of the mixing chamber and rise, where they are charged negatively while passing through the upper part of the deflector (not shown) and sucked from the port 16b. It is supplied to the combustion chamber 6 a via the air flow path 7.
