The present invention refers to the mechanical sector. More? in detail, it concerns a peculiar system that can be implemented on any vehicle comprising an internal combustion engine, preferably an engine in which magnetic components are present, capable of promoting the conversion of the CO2 produced by combustion into CH4 through UV-LED irradiation. All in order to consistently reduce CO2 emissions from the combustion of fuel in the atmosphere. Is this system also characterized? due to the fact that it includes components that allow the by-products of said conversion to be reused to further facilitate the same, all while significantly reducing the emission of harmful products into the atmosphere as well as? fuel waste and its optimization.

Known art

? I know that the planet's global climate has suffered and is suffering more and more. quickly, a change that essentially is not? due to phenomena related to the climate system itself? such as orogeny, epinogenesis, variations in ocean currents or astronomical factors such as eccentricity? of the Earth's orbit or the obliquity? of the earth's axis. One of the main causes? instead it is indisputably due to the increase in the production of CO2 and its release into the atmosphere with the result of contributing to the notoriously harmful greenhouse effect. The majority of CO2 emissions into the atmosphere today are also attributable to the increase in motorization and specifically to the production of CO2 as a by-product of combustion in vehicles equipped with internal combustion engines. In this regard, in recent decades there have been countless solutions adopted by car manufacturers aimed at reducing CO2 emissions into the atmosphere. In particular, ? The beneficial effect induced by fuel magnetization on the performance of internal combustion engines has been known for several years. More? in detail, ? It has been observed that by magnetizing the fuel or irradiating it with infrared rays, energy consumption decreases and harmful emissions are reduced. In light of these experimental observations, in recent decades, devices specifically designed to induce the magnetization of fuel in engines have been created. However, according to the diamagnetic behavior of most of the substances that make up the fuel, the effect of the magnetization induced by the magnets on the molecules present in it is ? relatively mild and also tends to decay over time. For these reasons, various solutions currently proposed indicate that the magnetization of the fuel must occur by immersing the magnets inside the tank in which it is stored. content in order to make s? that the induced phenomenon is the most? possible constant and long-lasting during combustion. A recent and innovative solution which, by exploiting the phenomenon of magnetization induced by magnets, allows obtaining high engine performance,? described in patent WO2012143804. The cited document, of which the present invention is, in some of its embodiments an evolution, refers to a method of treatment of the substances involved directly and indirectly in the combustion reactions of internal combustion engines. Said method involves the use of a set of devices comprising magnetic elements which are appropriately positioned on the fuel line: inside an immersion container(s) present in the tank containing the fuel; on the cooling duct and on the supply air duct. These elements, what? positioned, they induce effects which, surprisingly, optimize the reaction conditions during combustion. The above achieves the result of improving the overall performance of the engine in terms of reducing energy consumption and reducing harmful emissions. More? in detail, the substances and mixtures of substances that interact with the generated magnetic field are: fuel, air and cooling water. As ? known, these substances do not have the same properties? when immersed in a magnetic field. Water and fuel are in fact diamagnetic substances for which the induced magnetization has the opposite direction compared to that of the applied magnetic field, with the result that said substances are weakly repelled by the magnetic field itself. Otherwise, paramagnetic substances, such as the molecular oxygen contained in the air, when they are in the presence of a magnetic field, show a magnetization having the same direction and direction as that associated with the external field. Paramagnetic materials have magnetic dipoles that align with the external field, thus weakly attracted. The invention described in document WO2012143804 was born from studies carried out on combustion reactions, typical of internal combustion engines, in the presence of applied magnetic fields. It describes more specifically a system that optimizes the performance of these motors thanks to a set of magnetic devices specifically positioned in specific points of the motor itself. More? in detail these devices are:

1) At least one immersion box-type container represented by a common suitably perforated container, with a plurality? of openings designed to facilitate direct contact of the fuel itself with a plurality? of magnetic elements positioned inside said immersion container. The latter ? furthermore stably fixed inside the fuel tank with special welded brackets, which make it fixed inside the tank itself, taking into account the particular use of the engine, the size of the tank and its application on engines such as those of aircraft, boats , or any other means of terrestrial locomotion, regardless of whether it moves by rail, rubber or tracks, or airplane. The immersion container should preferably be placed close to of the fuel outlet pipe. Inside the immersion container(s) placed in the tank containing the fuel, there is at least one solid container of any shape, preferably cylindrical, containing within it a plurality of of magnetic elements represented by permanent magnets with a discoidal profile and including some elements from the rare earth group, such as samarium-cobalt-neodymium magnets. Ceramic spacers are interposed between said magnetic discoidal elements, also with a discoidal profile, suitably spaced to optimize the magnetic effect. Said solid containers, preferably cylindrical, are in turn stably anchored to the bottom of the immersion container to facilitate their contact with the fuel on which they must exert their magnetizing effect. The anchoring takes place via stable locking systems such as screws or brackets, in order to appropriately distance said solid containers from each other by at least 3 cm, so? to help optimize the generated magnetic field. Each solid container, placed inside the immersion container, in turn placed inside the tank as much as possible. as close as possible to the exit of the duct to power the motor so? the maximum quantity to be treated? of fuel, ? made in such a way as to favor the most? contact between the fuel contained inside the tank itself and said magnetic elements is possible. The materials with which the aforementioned containers are made are of various nature, as long as they are are insoluble in the fuel. Even their shape can? vary and their dimensions are obviously proportional to those of the engine on which they must be applied. The indicative height of each cylindrical container and consequently of the immersion element varies according to the flow rate of the supply flow and the type of engine subjected to the magnetization process from a minimum height of 6 cm, ideal for motorcycle tanks , well over 100 cm high to induce magnetization in ship engines, preferably the height of each cylindrical container? from 20 to 40 cm, the optimal one? of 30 cm. The density? of the magnetic flux generated by the container, when completed with the magnetic discs and ceramic spacers, ? of the order of 1.17 tesla. Magnetic disks comprise rare earth elements preferably neodymium.

2) The second device? represented by a solid structure of parallelepiped shape, in which the fuel pipe coming from the tank where it is located? containing the aforementioned immersion container, enters by performing a series of folds and/or curves in order to create a serpentine and/or a winding of tubes thus? what a plurality? of further magnets can be stably housed. The coil and/or the winding of the tubes contributes to the permanence of the magnetization previously induced in the fuel. In fact, the fuel that flows inside the duct made up of the coil, passing close to of the magnets present on it, is magnetized by said magnets which are preferably made of ferrite and/or with elements belonging to rare earths such as those in neodymium and/or samarium-cobalt.

3) The third device? represented by a set of pairs of magnets positioned in proximity? of the mechanical fuel supply pump and/or in the vicinity? of the injection point of the fuel itself into the engine combustion chamber. Furthermore, these pairs of magnets can be covered by a plurality? of neodymium washers designed to further increase the applied magnetic field. These magnets also have a curved profile, therefore presenting convexities? and concavity? in order to allow their adaptation to the surfaces of the components on which they are installed to be optimal.

4) The fourth device? represented by a further set of magnets, on which neodymium washers are possibly applied, arranged radially on the air intake duct thanks to a sealing band. The temperature that these magnets must withstand? of at least 110?C.

5) The fifth device? instead represented by a plurality? of magnets installed on the cooling duct connected to the radiator of the internal combustion engine and magnetize the water and/or the coolant. For these substances, considering the water and the cooling liquid, the magnetization will have? opposite direction to that of the external magnetic field, similarly to what happens for fuel, being also diamagnetic.

6) The sixth device? also represented by a set of magnets that come for? arranged around the fuel filter connected to the internal combustion engine. Also in this case, the profile of the magnets ? such as to allow their adaptation to the surface of the component on which they are installed to be optimal.

The system including the aforementioned devices ? can be installed on any combustion engine, regardless of whether it is powered by diesel, petrol, LPG, methane, kerosene or any other fuel.

The invention described in document WO2012143804 therefore refers to an efficient system of magnets which consistently optimizes the performance of the engine. The purpose of this patent application for an industrial invention, described in detail below, is? that of defining an innovative system for optimizing the performance of internal combustion engines, which can be implemented on any vehicle with this type of engine, which, in addition to significantly increasing the efficiency of the engine thanks to the peculiar and pre-existing presence of suitable magnets, in first of all, to induce the magnetization of the fuel, is such as to guarantee an equally significant reduction in CO2 emissions into the atmosphere as well as? the conversion of the latter into methane and its storage for use as a reserve fuel.

About that ? It is interesting to note that, to date, most national, European and international regulations are inducing more and more vehicle manufacturers to reduce CO2 emissions from cars by designing increasingly smaller vehicles. green. This is a fundamental aspect of combating climate change through mobility. more? green and to reduce the environmental impact linked to travel. ? I know that carbon dioxide is a gas normally present in the atmosphere, however? in quantity? rather limited. CO2, in fact, contributes to the greenhouse effect, as it affects the thermoregulation of the Planet.

A quantity? excessive use of this gas causes warming of the Earth's climate with negative impacts on the natural biosphere. The transport sector? one of the main causes of CO2 emissions. The CO2 emitted by cars? therefore a very serious problem, for this reason national and international institutions increasingly aim to the definition of programs aimed at reducing carbon dioxide emissions. In fact, the CO2 emissions produced by vehicles notoriously affect the ozone which protects the earth from ultraviolet solar rays, thus increasing global warming and, obviously, appreciably worsen the quality? of the air, especially in large cities.

Although many programs aim to abandon fossil fuel as an energy source in vehicles, the definitive end to its use is currently still doubtful or, in any case, presumably not imminent. In this regard, several studies in recent decades have focused on the development of processes that involve at least the conversion of CO2 into a reusable or non-harmful product at an environmental level or, even more, its reuse for different applications, for example in agriculture.

Of particular interest? the conversion of CO2 into methane. Recent studies have shown that an interesting conversion of CO2 into methane occurs through the interaction of a mixture of CO2 and hydrogen with UV rays in the presence of a catalyst, and in particular in the presence of a catalyst represented by metallic nano-particles, typically of Rhodium.

And therefore, the aim of the present invention, described in detail below, is? is to propose a system for optimizing the performance of internal combustion engines, which can be implemented on any vehicle that uses this type of engine, which, in addition to contributing to the efficiency of the engine thanks to a peculiar magnetization induced in its components and especially in fuel, involves a significant reduction in CO2 emissions into the atmosphere as well as? the conversion of this substance into methane or into reserve fuel that can be usefully reused within the same engine.

Description of the invention

This description refers to a peculiar system for optimizing the efficiency of internal combustion engines and for the substantial reduction of CO2 emissions into the atmosphere as well as? for the conversion of the latter into further reusable fuel. The said system? advantageously implementable on any vehicle on which? an internal combustion engine installed/can be installed.

How already? mentioned, the said invention in addition to preferably exploiting the effect of magnetization, induced on all the components described in the aforementioned prior art document, and primarily induced in the fuel, which as known consistently improves the performance of the engine in terms of efficiency, consumption and reduction of harmful emissions, overall resulting from a greater conversion of the said fuel during the combustion process, offers the important advantage of converting the CO2 in this way. produced in CH4.

The said system is therefore characterized by the fact that it includes a specific section for the conversion of CO2 into methane, as well as? for the possibility? to store methane like this? obtained inside the vehicle on which it was purchased. installed the said system.

? It is interesting to point out that the said invention exploits the results of an important study carried out by researchers at Duke University who found a way to convert carbon dioxide into methane using UV rays as an energy source. More? in detail, this reaction occurs thanks to the use of rhodium nanoparticles which, in addition to promoting the conversion, also favor? a greater formation of methane, instead of? an equal mix of methane and unwanted products such as carbon monoxide.

? else? It is interesting to report that, normally, by heating the nanoparticles to high temperatures of around 300 degrees centigrade, the conversion reaction triggered produces methane and carbon monoxide in equal parts. Otherwise, without heating but by irradiating the nanoparticles with preferably high-power ultraviolet LED lamps, the reaction occurs at room temperature and produces almost exclusively methane.

For the purposes of greater exhaustiveness? descriptive? It is interesting to report that the said study has in fact found that when rhodium nanoparticles are hit by ultraviolet rays produced by UV-LED lamps, they capture the energy and direct it to promote specific chemical reactions. In particular, if irradiated within a mix of hydrogen and CO2, the said rhodium particles induce the two molecules to recombine, almost exclusively forming methane molecules.

The system according to the present invention, exploiting the aforementioned modality? of conversion of CO2 into methane, allows the transformation of the CO2 produced by the combustion of the fuel inside an internal combustion engine, previously confining it in a particular conversion chamber, and subsequently transforming it into methane. All this? involves a significant reduction in CO2 emissions into the atmosphere from the vehicle's exhaust pipe.

More? in detail, said conversion system includes, in turn, a UV irradiation system, preferably made with UV-LED emitters, found in the duct that conducts the burnt fuel, or the combustion products, to the exhaust pipe. In this duct? else? interposed is the said conversion section which includes at least one chamber represented by a jacketed and thermostated tank, in order to maintain the temperature inside the tank as much as possible. possible constant and preferably at the ambient T value, and within which molecular H2 flows.

Inside the said jacketed tank, there is present a catalyst represented by metal nanoparticles, preferably rhodium, designed to promote the conversion of CO2 into methane.

At the exit of the said jacketed tank? else? There is a filtration system that separates the methane, so? obtained from the other components possibly present in the jacketed conversion tank, as well as from the possibly unconverted CO2, and from which the said methane is conveyed and stored inside a special storage tank designed to act as a fuel reserve, in this case methane indeed.

The system, according to the present invention, also provides that at the outlet of said jacketed tank, there is a filter which allows both the passage of CO, produced by combustion and also present as a possible by-product of the conversion reaction of CO2 into CH4, and its confinement inside a tank for the CO. More? in detail, the system in question provides for the said CO to be conveyed into a further tank suitably placed for the CO, in which it is water is present which, reacting with CO through the well-known water gas displacement reaction, produces CO2 and H2. Through special ducts, the CO2 like this? obtained from the water gas displacement reaction, it is conveyed inside the jacketed tank for its conversion into methane, while the hydrogen is conveyed inside a special hydrogen tank which is designed to provide the further component, i.e. hydrogen, necessary to carry out the reaction of conversion of CO2 into methane.

The said system? furthermore such as to include a specific electrolytic cell for the electrolysis of water capable of providing the hydrogen necessary for said conversion from which the said gas flows into the specific hydrogen tank and from which it is then conveyed into the tank conversion jacket.

The other product of water electrolysis, i.e. O2, is instead conveyed inside the combustion duct, air. This procedure consistently optimizes the combustion process, minimizing consumption, reducing harmful emissions and also reducing? fuel waste.

All residual combustion products not converted into methane escape from said jacketed conversion tank, flowing into a duct that leads them to the exhaust pipe.

Advantageously, the important and primary effect that follows from the use of the system in question is? that of consistently reducing the emission of CO2, coming from the combustion of fuel in the atmosphere, as at least 50% of this is convertible into methane.

Advantageously, methane is so obtained turns out to be an important and useful source of reserve fuel that can? alternatively be used within the same internal combustion engine, where the characteristics of the latter are such as to allow it to be powered by methane, or it can be used be taken to recovery centers that operate for the discharge of said storage tanks, thus making them? again available to accept further methane produced by the conversion of CO2 promoted by UV radiation.

Another advantage, as already? said, ? that the conversion reaction can? occur effectively at room temperature, thus avoiding the energy expenditure to facilitate the conversion which, typically and in the absence of a catalyst and UV rays, would require decidedly higher temperatures? high, as well as precision systems for controlling reaction conditions.

Additional advantage? that the system in question uses UV-LED emitters which, compared to traditional UV bulb lamps, are characterized by low consumption while emitting the same light energy.

? Finally, it should be noted that the large-scale use of the system according to the present invention on pre-existing or newly developed vehicles would make it possible to reach the target of reducing CO2 emissions into the atmosphere in a relatively short time, as well as offering the additional advantage of promoting the conversion of CO2 into methane with greater yield when catalyzed in the presence of UV-LED irradiation.
