Definitions
- the invention relates to a device for the pretreatment of oxidizer upstream of its injection into the inlet of an internal combustion device. It also relates to a vehicle equipped with such a device as well as internal combustion boilers provided with a routing of the oxidizer to the air filter specific to the engine and to the boiler and or hearth.
- This device can be used with any type of thermal engine, also called internal combustion engine, as well as internal combustion boilers.
- An internal combustion engine and boiler use the reaction of a fuel and an oxidizer, the latter generally being the oxygen in the air and a certain level of humidity, to transform the thermal energy produced by the reaction of combustion into mechanical work or the production of energy.
- fuel we mean here a fuel derived from petroleum products, for example gasoline, unleaded gasoline, gas oil or a fuel belonging to the category of bio-fuels or bio-mass, for example an oil vegetable or an alcohol or a so-called bio-mass wood.
- oxidant is meant a substance which has the property of allowing the combustion of a fuel.
- thermal energy is provided by the combustion of a fuel in liquid or solid form in the presence of a gaseous oxidant, the oxygen in the air.
- the gas resulting from this combustion is used, during an expansion phase, to set in motion mechanical parts located, for example, in a vehicle, a pump, a compressor or in other devices producing movement and energy in general.
- combustion is used to produce thermal energy which can also be transformed into other energy (electrical for example).
- the products, in gaseous form, resulting from combustion are discharged outside the engine onto public roads in general. Due to the anti-pollution standards in force and the scarcity of petroleum products, it is advantageous to limit the gaseous emissions resulting from the combustion in such engines while improving the efficiency by the quality of the combustion and the fuel consumption of the engine. these engines and boilers.
- This part of the exhaust gases also known as "EGR gas”
- EGR gas This part of the exhaust gases, also known as "EGR gas”
- P is also known that the oxidant is the most consumed element during combustion by an internal combustion engine, whether in mass or in volume.
- the various known stoichiometric ratios being: for diesel, 1 gram of diesel oil requires at least 15 grams of air. For gasoline 1 gram of fuel requires about 17 grams of air. For ethanol: 1 gram of fuel requires approximately 9 grams of air.
- refined fuel can increase the efficiency of an internal combustion engine. It is also known to inject water into the air and exhaust gas mixture. The combustion temperature of the fuel/oxidizer mixture is thus lowered and the emission of certain pollutants is limited, in particular NOx or nitrogen oxides such as NO (nitrogen oxide) or N02 (nitrogen dioxide). These pollutants combine with water to form certain compounds, such as nitric acid. The addition of water by reducing the combustion temperature preserves the engine components, avoiding overheating of the latter, while limiting the need for thermal energy necessary to bring the fuel/oxidant mixture to combustion temperature.

- the member 2 is in this embodiment connected by a pipe 3, schematically illustrated in Fig.l, to the member 2.
- the pipe 3 is made of a material insensitive to environmental conditions and resistant to heat; it is, for example, a flexible or rigid metal pipe 3, made of stainless steel, the dimensions and size of which are adapted to the mounting conditions of the device in the environment of the engine or of a boiler and its circuit air intake.
- An air inlet end 1, located in the direction of travel or in the environment of the pipe 3, is fixed to the outlet of the member 2 and the other end is fixed to an inlet connection 4 of the formatting chamber 5.
- a transfer cannula 7 is connected to an outlet connection 6 of the formatting chamber.
- the assembly of the pipe 3 is carried out in a removable manner, for example by threaded rings, on the cannula 7 and on the outlet of the member 2.
- the air treatment chamber 5 (FIGS. 2 and 5) is defined by a duct 55 comprising treatment members embedded in a network of magnetic or ferromagnetic fibers 52.
- the treatment members also called homogenization, comprise a central and longitudinal axis 51 of magnetic or ferromagnetic material, and being provided with magnetic elements 53.
- said magnetic elements are arranged along the central axis 51 in field opposition and alternating with ceramic elements 52. It is thus possible to optimize the combustion of an engine, that is to say the ambient air passing through the chamber with a frequency and coercive field induced by the elements magnetic elements, as well as concentrating the water molecules at the level of the ceramic elements.
- the integration of the ceramic elements inside the air treatment chamber 5 makes it possible to reduce the number of elements necessary to optimize the oxidant, by eliminating the need for a water injection device. . This also facilitates the installation of the chamber, requiring only simple connections to be connected to the motor.

It is therefore possible to optimize the combustion of an engine without the need for additional injection of water. It is currently not understood the mechanism of action of this improvement, however the results are clear as regards the improvement of the combustion, and the reduction of the fuel requirement of up to 22%.
- This alternating composition of ceramics would seem to capture the water vapor, and modify the flow and concentrating that water vapor passing through the treatment chamber. It would seem that the induction of a magnetic field on the water molecules is also optimized by the presence of alternating ceramics.

- the ceramics are chosen from ceramic beads for insulating electric cables produced for example from steatite.
- the chamber 5 is configured as a stainless steel braid provided with a non-magnetic shield suitable for balancing the pressure in the chamber. It is located near the inlet 20, the pipe 3 then being of a minimum length to be free for the acquisition of air. In another embodiment, the distance between the two chamber connection points 2, 4 depends on the mounting conditions of the device and the space available in the vicinity of the motor. Chamber 4 is also remote from member 2.

- the passage allows the air to be formatted before it enters the engine's own air filter.
- the formatting chamber 5 is flexible and it has the overall shape of a non-exhaustive tube. Such a flexible shape makes it possible to position it in the engine compartment against an element located in the vicinity of the engine, in order to facilitate the attachment of the device while minimizing the overall size of the device.
- the fixing of the formatting chamber 5 is facilitated by a flexibility due to its composition.
- This chamber is for example a flexible stainless steel hose, a known industrial product.
- the chamber 5 has a tubular (non-exhaustive) and flexible shape, so as to define an air line path inside the formatting chamber 5, between the inlet 4 and the outlet of the chamber 6. It should be noted that on installation, chamber 5 has no direction of installation. As a variant, the formatted oxidant is admitted directly into the intake collection pipe before the engine air filter and without passing through a transfer nozzle.
- organs 51 52 53 and 56 are inserted in a central position in the chamber 5 and comprise:
- a network of water-repellent magnetic or non-magnetic fibers 52 such as a sheathing and water-repellent ferrous textile ribbon, for example a stainless steel wool;
