Abstract

PURPOSE:To obtain the device for passing the fuel oil through a magnetic field, capable of improving the combustion efficiency of the fuel oil by passing the fuel oil to be used for an internal combustion engine of an automobile, a vessel or the like, through a magnetic field immediately before burning. CONSTITUTION:A magnetic field as a whole of permanent magnet groups 15 constituted by connecting different poles of an anisotroipic sintered magnet mainly composed of neodymium, iron and boron by a magnetic force, is produced between the upper end and the lower end. Since neighboring ends of two sets of permanent magnet groups 15 and 15 have the same pole, the interposed part 13a of a sleeve 13 acts as one magnetism collecting part, and further a cylindrical member 17 acts as another magnetism collecting part. When the fuel oil passes through a space formed between the inner peripheral surface of the interposed part 13a in a magnetic field forming oil passage 19 and the outer peripheral surface of the cylindrical member 17 opposing thereto, the fuel oil is subjected to a physicochemical change by the operation of a strong magnetic force which is generated between both surfaces, and thus the combustion efficiency is improved.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention involves passing fuel oil, such as gasoline, light oil, and heavy oil, used as fuel for internal combustion engines of automobiles, ships, etc., through a magnetic field immediately before combustion. The present invention relates to a magnetic field passing device for fuel oil that improves the combustion efficiency of fuel oil.

[Conventional technology]

For example, combustion efficiency can be improved by passing a magnetic field through fuel oil just before it is combusted in an internal combustion engine.
This is already a well-known fact from Japanese Patent Publication No. 38-9354, Japanese Patent Application Laid-Open No. 59-176504, and Japanese Patent Application Laid-open No. 60°-259761. In this case, the above-mentioned special public interest public
Although the technologies described in No. 9354 and JP-A-59-176504 are configured such that fuel oil passes through magnetic fields formed by permanent magnets, these magnetic fields are Since only the magnetic force acts, the magnetic force is weak, and therefore the physicochemical influence on the fuel oil is small, and the combustion efficiency is not improved much.

On the other hand, the structure disclosed in JP-A No. 60-259761 has a structure in which the magnetic forces of a plurality of permanent magnets are superimposed so that the sum total is output. Although it is expected that the combustion efficiency will be improved over the conventional techniques, there is still a problem in that the magnetic field is generated in several locations, so it is still not completely satisfactory.

Therefore, in order to deal with such problems, the magnetic force of a plurality of ring-shaped permanent magnets is aggregated into a set of permanent magnets, and the magnetic force of this permanent magnet set is aggregated between two magnetic collecting members facing each other. A magnetic field passing device for fuel oil has been proposed or used, in which a strong magnetic force is generated from pole protrusions formed at the ends of both magnetic collecting members, and the fuel oil is configured to pass between these pole protrusions. is being attempted. According to this device, when the fuel oil passes between the pole protrusions of the two magnetic collecting members, a strong magnetic force imparts a suitable physicochemical influence to the fuel oil, and the fuel oil is It is expected that the combustion efficiency of the internal combustion engine used can be effectively improved.

[Problem that the invention seeks to solve]

However, even with this device, there are still problems to be solved in order to more effectively improve combustion efficiency.

That is, this device uses samarium cobalt magnets (or ferrite magnets) as permanent magnets, and it cannot be said that the magnetizing force or maximum magnetizing energy product of this type of magnet is necessarily a sufficient value. Moreover, it has the disadvantage that its specific gravity is relatively large, and furthermore, its bending strength and tensile strength are inferior. Therefore, when configuring a fuel oil magnetic field passing device using this type of magnet, a large amount of magnets is required in order to generate a desired strong magnetic field in the device, and this causes problems in the device. This results in an increase in the size and weight of the device, as well as complicating the structure of the fuel oil passages within the device and causing problems in terms of layout.

[Means for solving problems]

This invention has been made in view of the above circumstances, and its means is such that a fuel oil introduction passage and a fuel oil discharge passage are arranged so that their adjacent ends are of the same polarity, and that neodymium , two sets of permanent magnets formed by magnetically connecting a plurality of ring-shaped permanent magnets with different polarities mainly composed of iron and boron, and a magnet fitted on the outside of these two sets of permanent magnets. a sleeve made of a magnetic material and having an intervening part that is fixed and interposed between adjacent ends of the two sets of permanent magnets; A through hole is provided to communicate the fuel oil introduction passage and the magnetic field forming oil passage, and adjacent ends of the two sets of permanent magnets are provided with a communicating magnetic field forming oil passage therebetween. and a cylindrical member made of a magnetic material and having a flange member fixed to each end on the opposite side.

[Effect]

According to the above means, the fuel oil led from the fuel tank to the fuel oil introduction passage of the magnetic field passing device passes through the through hole of the cylindrical member communicating with the fuel oil introduction passage, and then passes through the two sets of permanent magnet sets. The fuel oil passes through a magnetic field forming oil passage which is interposed between the magnetic field forming oil passage and the cylindrical member and communicates with the through hole, and is then discharged from the internal combustion oil discharge passage which communicates with the magnetic field forming oil passage. Supplied to institutions.

In this case, since the two permanent magnet sets are each constructed by connecting members of different polarity with magnetic force, the overall magnetic field of each permanent magnet set is between one end and the other end of each permanent magnet set. Moreover, since the adjacent ends of the two sets of permanent magnets are arranged to have the same polarity, the adjacent ends of the two sets of permanent magnets An intervening part of a sleeve interposed therebetween acts as one magnetic collecting part, and a cylinder has a collar member fixed to an end opposite to an adjacent end of the two sets of permanent magnets. The shaped member acts as the other magnetic flux collector. Therefore,
When the fuel oil flows into the magnetic field forming oil passage and passes between the interposed part and the cylindrical member, the magnetic force generated between the two causes a physicochemical change in the fuel oil. It turns out.

Furthermore, since each of the permanent magnets constituting the two sets of permanent magnets is an anisotropic sintered magnet whose main components are neodymium, iron, and boron, its magnetizing force or maximum magnetizing energy product is It is large and has a small specific gravity (and has excellent bending strength, etc.), so even if a small and small number of permanent magnets are used, there is a sufficient size between the intervening part and the cylindrical member. Magnetic force will be generated.

Next, the operation of this first embodiment having the above configuration will be explained.

First, fuel oil led from a fuel tank (not shown) to the fuel oil introduction passage 9 in the upper cover member 5 of the casing 2 via the oil guide pipe 11 passes through the cylindrical member 170 as shown by the arrow in FIG. After passing through the hole 16 and flowing into the internal space of the bottom cover member 7, foreign matter is removed by a filter 22, and then flowing into the magnetic field forming oil passage 19 via the oil passage hole 21 of the collar member 18. Then, this fuel oil is transferred to the magnetic field forming oil passage 1.

〔Effect of the invention〕

As described above, according to the present invention, when fuel oil passes through the magnetic field forming oil passage provided in the magnetic field passing device, a strong force is generated between the interposed part of the sleeve and the cylindrical member. Due to the action of the magnetic force, suitable physicochemical changes occur in the fuel oil, so that the combustion efficiency of the fuel oil in the internal combustion engine is significantly improved and fuel consumption is reduced.

Furthermore, since an anisotropic sintered magnet containing neodymium, iron, and boron as the main components was used as a permanent magnet that is a component of this magnetic field passing device, there is a gap between the interposed part of the sleeve and the cylindrical member. Not only is it possible to make the generated magnetic force stronger than before, but it also makes it possible to downsize and reduce the number of permanent magnets, which in turn makes the magnetic field passing device lighter and more compact. This will solve layout problems and the like.
