DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The object of this invention is a magnetic-polarization device that can be used to improve the degree of atomization of a fuel that is to be injected and then combusted, as is done in, e.g., internal-combustion engines with fuels of any type (gasoline, diesel fuel, alcohols), in burners, and in heaters.
BACKGROUND OF THE INVENTION
It is known that, by improving the atomization of the jet of fuel and reducing the mean diameter of the injected droplets, the process of evaporation and/or heating to the temperature where combustion starts is accelerated, thus primarily ensuring a lower combustion temperature overall; this has a beneficial effect on the yield of the relative thermodynamic cycle and improves combustion overall, while reducing uncombusted and partially combusted components such as CO.
Magnetic-polarization devices are already known that subject the fuel, circulating in a feed circuit, to predetermined concatenated magnetic fluxes with permanent bar magnets, behind which the fuel is made to flow before it is injected.
An example is disclosed in U.S. Pat. No. 4,201,140:
In terms of its design and the arrangement of its parts, magnetic and non-magnetic, this kind of device calls for external shielding, which is expensive and difficult to produce, and achieves polarization results that are less good than those of the device of this invention owing to the different arrangement of the lines of flux, as will be further explained below. In particular, flux carrying members, that will be described below, are not present in any example of the prior art.
It is known that the most probable theory that accounts for the results mentioned above postulates that the polarization treatment reduces the electromagnetic forces of cohesion between molecules that have polar axes oriented in different ways.
As a result, better polarization of the molecules that make us the fuel corresponds to more energetic action of the magnetic fluxes which have a direction that varies abruptly as the fuel flows along the magnets; the molecules, whose polar axes tend to line up under the action of the external magnetic flux to which they are subjected, thus lose the order that creates the cohesion among the molecules themselves.
This is achieved with the device according to the invention which, as already mentioned, also turns out to be less expensive than those known to the current state of the art.
SUMMARY OF THE INVENTION
The object of the invention consists of a magnetic polarization device for a fuel supply circuit for burners or for internal-combustion engines comprising parallel multi-pole bar magnets (2) lodged inside a casing (6) that forms inside of itself passage vanes (9) through which said fuel can flow, wherein each of said multi-pole bar magnets (2) is made up of an odd number of contiguous bipolar magnetic segments (2a, 2b, 2c) that are aligned axially, facing one another with like-directed magnetic polarities, and thus having polarities of opposite directions corresponding to the ends of each bar (2), characterized in that said magnetic segments have concatenated magnetic fields of increasing intensity, as well as in that, between each pair of multi-pole bar magnets (2), equidistant from the latter, is arranged one parallel flux carrying bar (3, 3e) that is made of a ferromagnetic material, so as to generate a plurality of flux lines that traverse, with flux rising along each bar (3, 3e) zones (9) through which passes the fuel to be treated.
