DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0191] As illustrated in the drawing of FIG. 1, the earth housing the forest coverage, factories, cars and human population is denoted G. The atmosphere is denoted A and is illustrated with its main elements represented within circles: [0192] dinitrogen=>N2 circles, [0193] dioxygen=>O2 circles, [0194] carbon dioxide=>CO2 circles.

[0195] This drawing depicts the situation at the beginning of the development of internal combustion vehicles, where there was a greater presence of forest coverage, very few factories, very few cars and a small human population. There was also a very significant presence (not shown) of phytoplankton.

[0196] The drawing in FIG. 2 illustrates the current situation of the earth G and the atmosphere A with a significant loss of forest coverage, a lot of factories, a lot of cars and a large human population. There are less and less phytoplankton (not shown). A decrease in oxygen in the atmosphere of the earth is to be noted.

[0197] The drawing of FIG. 3 illustrates the current mode of combustion of fossil fuels by using air from the atmosphere A. The furnace denoted 30 positioned on the earth G comprises a combustion chamber 31 supplied with fossil fuel (arrow 32) and by air (arrow 33) from atmosphere A, i.e. in particular by a mixture of dinitrogen N2 and dioxygen O2. The releases (arrows 34) are hot gases which in particular include carbon dioxide and nitrogen oxide NOx. The releases of steam and hot nitrogen are shown by arrow 35.

[0198] The consequences of using this type of combustion are: [0199] a reduction in the oxygen content in the atmosphere A of the earth, [0200] heating by injecting hot gases into the atmosphere A of the earth (including hot nitrogen), and [0201] production of harmful substances such as NOx.

[0202] FIG. 4 illustrates one of the technical solutions of the invention for the purpose of preserving the oxygen content of the air in atmosphere A consisting in using a furnace 40 with a combustion chamber 41 receiving a fossil fuel (arrow 42) and produced pure oxygen 45 intended for its injection (arrow 43) into the combustion chamber 41 of the furnace 40. In comparison with the drawing of FIG. 3, an absence of production of NOx and a higher presence of oxygen in the atmosphere A of the earth and a reduction in the concentration of carbon dioxide in the atmosphere of the earth is to be noted, since oxygen in the air is no longer consumed. The use of pure oxygen also avoids the release of hot nitrogen.

[0203] As described above, oxygen can be produced and injected directly into said furnace, engine, etc. or be produced to compensate for that used elsewhere.

[0204] FIG. 5 illustrates another of the technical solutions of the invention for the purpose of preserving the oxygen content of the air of the atmosphere A consisting in using a hearth 50 with a combustion chamber 51 receiving a fossil fuel (arrow 52) and pure oxygen 56 resulting from the decomposition of hydrogen peroxide 55 produced. Here too, in comparison with the drawing in FIG. 3, an absence of production of NOx and a greater presence of oxygen in the atmosphere A of the earth and a reduction in the concentration of carbon dioxide in the atmosphere of the earth can be noted, since the oxygen in the air is no longer consumed. The use of pure oxygen also avoids the release of hot nitrogen.

[0205] FIG. 7a illustrates one embodiment of an engine 70d using pure oxygen. As illustrated, this engine 70d includes a combustion chamber 70c supplied with oxygen from a pure oxygen tank 70a and with fossil fuel from a fossil fuel tank 70b. A heat exchanger 70e ensures the cooling of the engine 70d. A pump 70f ensures the displacement of the coolant 70g.

[0206] According to a possible option, the hot gases 70h resulting from the combustion are recycled (through the pump 70i) to be mixed with the fossil fuel/pure oxygen mixture and to be injected (reference 70k) into the engine 70d for the purpose of combustion optimization.

[0207] To avoid damaging engine parts, the cooling capacity of the heat exchanger 70e is significantly greater (up to twice) than the capacity of heat exchangers of current common vehicles. As a result, the pump 70i is also of higher capacity than current pumps.

[0208] FIG. 7b illustrates one embodiment of an engine 70d′ using oxygen extracted from atmospheric air. According to the invention, this embodiment is associated with a compensation of pure oxygen produced remotely. It uses the various elements of the engine 70d illustrated by the drawing of FIG. 7a. Compared with the embodiment illustrated by the drawing of FIG. 7a, it differs from the latter in that it is equipped, upstream the pure oxygen tank 70a′, with an extractor of the oxygen from the air 70l′.

[0209] FIG. 7c illustrates one embodiment of oxygen production or compensation that may be associated with the operation of engine 70d′ described above. This embodiment comprises the following steps: [0210] a step of production of oxygen (O.sub.2) by the culture of phytoplankton 70n in oceans, seas, rivers, lakes (denoted 70m), [0211] a step of rejecting this oxygen produced by phytoplankton 70n in the atmosphere of the earth 70p and, [0212] a step of extracting this oxygen (O.sub.2) in the atmospheric air 70q by means of an extractor 70l′ illustrated in the drawing of FIG. 7b, and of sending this extracted oxygen (O.sub.2) to the storage tank 70a′.

[0213] This same Figure can be used as an illustration for another embodiment of which the only difference lies in the fact that the production of oxygen takes place by electrolysis of water by solar means (photolysis) and not by culture of phytoplankton.

[0214] The drawing of FIG. 8 illustrates an implementation of the cooling of combustion gases participating in the operation of a wheeled vehicle denoted 80.

[0215] FIG. 8 illustrates a combustion gas cooling device participating in the operation of a wheeled vehicle denoted 80 as a whole. This device comprises a hot gas-air condensation heat exchanger 81 which receives through the inlet 82 hot combustion gases which exit once cooled through the outlet 83. The device comprises a supply pipe 84 for hot combustion gases 86 from the engine of the vehicle 80 to the heat exchanger 81 and an outlet pipe 85 for the cooled combustion gases 87, freed of water vapor, returned to the rear of the vehicle 80. The cooling air 88 is received at the front of the vehicle 80 during the movement of the latter (arrow F1). The air 89 having served for cooling the combustion gases and for condensing the water vapor contained in these gases is discharged at the rear of the vehicle 80. However, as illustrated, the inlet 82 for the hot combustion gases is located on the rear part of the exchanger 81 while the outlet 83 of the cooled gases is arranged at the front of the exchanger 81. The enclosure formed by the exchanger 81 is also equipped with means for discharging the condensates represented by taps. Partitions denoted CI separate the pipes 84 and 85 from the body of the exchanger 81 to avoid a direct exchange between the pipes and the exchanger.

[0216] FIG. 9 illustrates a vehicle 80′ equipped with a combustion gas cooling device participating in the operation of the vehicle equivalent to that illustrated in the drawing of FIG. 8 but with the specific feature of storing the cooled exhaust gases. To do this, the vehicle 80′ is equipped with a sub-assembly for recovering said cooled gases. Thus, the outlet 83′ of the exchanger 81′ leads to a storage tank 100′ for the cooled combustion gases. A compression pump 101′ and a non-return valve 102′ controls the filling of this volume from the outlet 83′. A valve 103′ controls the discharging of said tank 100′. As an alternative or in addition to the concentration, said storage tank contains one or more chemical reagents in solid and/or liquid form for dissolving and or chemically neutralizing CO2. This embodiment is also equipped with partitions, here denoted CI′.

[0217] The vehicle 200 illustrated by the drawing of FIG. 10a comprises the means for cooling and storing the combustion gases of the vehicle 80′ of FIG. 9 with in addition means for filling with pure oxygen, with fuel, and for discharging the stored combustion gases. Thus, in addition to the various sub-assemblies described for the vehicle 80′, this vehicle 200 comprises a pure oxygen tank 201 with a starting line 202 towards the engine (not shown) of the vehicle 200 and a filling line 203 emerging on the outside. The fuel tank is here denoted 204 with a starting line 205 to the engine (not shown) of the vehicle 200 and a filling line 206 emerging to the outside. According to the non-limiting embodiment illustrated, the fuel and oxygen inlets and the outlet of the sequestered gases are grouped together in proximity to each other. Such a configuration will make it possible to group together the operations of filling and discharging the vehicle.

[0218] The drawing of FIG. 10b illustrates a vehicle 200′ equivalent to that denoted 200 illustrated by FIG. 10a but which is equipped with a means for extracting oxygen from the air. Thus, in addition to the various sub-assemblies described for the vehicle 200, this vehicle 200′ comprises an oxygen extractor 207′ for extracting oxygen from the air with a pipe 208′ ensuring the connection between the oxygen extractor 207′ and the oxygen tank 201′.

[0219] FIG. 11a illustrates an embodiment of a plant denoted 300 which comprises three tanks associated with pumps in order to manage the supply of fuel, oxygen and the recovery of exhaust gases. The plant 300 thus comprises a liquid oxygen reservoir 326 associated with a liquid oxygen pump 327 for filling the vehicle with oxygen (not shown but corresponding to that equipped with a fuel tank, an oxygen tank and gas storage tank). The plant 300 also includes a combustion gas storage tank 328 associated with a pump 329 for withdrawing the combustion gases stored in the vehicle tank. This pump 329 also serves as a compressor.

[0220] The plant finally comprises a reservoir 330 of liquid or gaseous fuel associated with a pump 331 for filling the vehicle with liquid or gaseous fuel. Each tank or reservoir is equipped with a pipe to which is connected the pump with which they are associated.

[0221] The ends of these pipes are assembled and each equipped with an end fitting capable to be connected, so as to connect with the inlets and outlets of the vehicle, for example for the vehicle 200 of FIG. 10a. The end fittings are assembled on a service gun 338 allowing a user to manipulate the three nozzles simultaneously when filling the fuel and oxygen tanks and when discharging the gases.

[0222] FIG. 11b shows a plant 300′ for filling the vehicle with fuel and for discharging the combustion gases, being a variant of the plant 300 in that it is suitable for filling and discharging a vehicle equipped with an oxygen extractor such as the vehicle 200′ illustrated by the drawing of FIG. 10b. Plant 300′ then only includes two tanks: [0223] a combustion gas storage tank 328′ associated with a pump 329′ for withdrawing the combustion gases stored in the tank of the vehicle. This pump 329′ also serves as a compressor, [0224] a reservoir 330′ of liquid or gaseous fuel associated with a filling pump 331′ for filling the vehicle with liquid or gaseous fuel.

[0225] Each tank or reservoir or is equipped with a pipe to which is connected the pump with which they are associated.

[0226] The ends of these pipes are assembled and each equipped with an end fitting capable to be connected, so as to connect with the inlets and outlets of the vehicle, for example for the vehicle 200′ of FIG. 10b. The end fittings are grouped together on a service gun 338′ allowing a user to manipulate both end fittings simultaneously during the fuel tank filling phase and the gas discharging phase.

This device comprises a heat accumulator 349′ containing hot-melt substances 342′, a circuit 340′ for exchanging heat between the hot combustion gases and the hot-melt substances 342′, a circuit 341′ for exchanging heat between a liquid or a cold gas 343 to be heated and the chemical substances 342′ which are melted by recovery of sensible and latent heat of the hot combustion gases 86, means 347′ for filling the heat accumulator 349′ with hot-melt substances 342′, means 348′ for withdrawing (discharging) hot-melt substances 342′ from the accumulator 349′. The exchange circuit 341′ includes an inlet 344′ for the liquid or gas to be heated and an outlet 345′ for the outlet of the liquid or the heated gas. The inlet 344′ and the outlet 345′ can be fitted with sealing plugs. Circuit 341′ may contain a circulation pump. The exchange circuit 341′ may have isolation valves Ve′ and Vs′. These valves can be controlled remotely.

[0295] According to another feature of the invention, the device comprises a second heat exchanger 346′ of the combustion gas-air, combustion gas-water or combustion gas-air-water type allowing secondary cooling and condensation of the residual water vapor contained in the combustion gases leaving the outlet 83. This second exchanger 346′ is connected to the heat accumulator 349′.

[0296] While driving the vehicle, the hot combustion gases 86 melt the hot-melt substances 342′ through the exchange circuit 340′. The melted hot-melt chemical substances form a liquid which remains in the heat accumulator 349′. The cooled gases then pass into the heat exchanger 346′ in which they undergo secondary cooling and in which they are freed of the residual water vapor they contain, before leaving through the outlet 87. Once the vehicle has arrived at home or on a heat recovery site, the inlet 344′ is connected to the source of gas or liquid to be heated and the outlet 345′ is connected to the storage tank for the heated liquid or gas.

[0297] FIG. 16 illustrates a heat recovery infrastructure installed at the parking point or at the vehicle stop and storage point.

[0298] FIG. 17 is an exemplary embodiment of the liquid (LF) or gas (GF) storage tank and the use of this heated liquid or gas.

[0299] It is understood that the method, device, vehicles and plants, which have just been described and shown above, have been described and shown for disclosure rather than limitation. Of course, various arrangements, modifications and improvements can be made to the above examples, without departing from the scope of the invention.
