Abstract

PURPOSE:To provide effectively a combustion efficiency of fuel oil by a method wherein a powerful magnetic field generated between adjoining end parts of two sets of permanent magnets is acted when the fuel oil passes through a magnetic field forming oil passage. CONSTITUTION:Fuel guided to a fuel oil introducing passage 9 passes through a through-pass passage 14 of a cylindrical member 13 and flows into an inner spacing of a bottom lid member 7, thereafter the fuel passes through an outer circumferential oil passage 19 of a set of magnets, a magnetic field forming oil passage 20, a fuel oil discharging passage 10 and a discharged oil pipe 12 and is supplied to an internal combustion engine. When the fuel oil passes through the magnetic field forming passage 20, a physical and chemical variation is applied to the fuel oil through an action of powerful magnetic field generated between the adjoining ends of two sets of permanent magnets 16 and 16 connecting the different poles of each of two permanent magnets 15 and 15. Each of the permanent magnets 15 and 15 is of anisotropic sintered magnet having as its major constituent neodymium, iron and boron.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention is directed to 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. 3B-9354, Japanese Patent Application Laid-Open No. 59-176504, and Japanese Patent Application Laid-open No. 60-259761. In this case, the said Special Publick Publication No. 38-9
Although the technology described in No. 354 and JP-A-59-176504 is configured such that fuel oil passes through a magnetic field 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 the fuel oil introduction passage and the fuel oil discharge passage are arranged so that their adjacent ends are of different polarities, 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 on the inner peripheral side of these two sets of permanent magnets. a cylindrical member arranged and having a through path; and a magnet set formed between an inner peripheral surface of one of the two permanent magnet sets and an outer peripheral surface of the cylindrical member. an inner peripheral oil passage; a magnet assembly outer peripheral oil passage formed on the outer peripheral side of the local permanent magnet assembly of the two permanent magnet sets;
a magnetic field forming oil passage formed between adjacent ends of the permanent magnet sets to communicate the magnet assembly inner circumferential oil passage and the magnet assembly outer circumferential oil passage, the upstream end of the through passage; is connected to the fuel oil introduction passage, and the upstream oil passage of the magnet assembly inner peripheral oil passage and the magnet assembly outer peripheral oil passage is connected to the downstream end of the through passage, and the downstream oil passage is connected to the downstream end of the through passage. The fuel oil discharge passages are connected to the respective fuel oil discharge passages.

[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 passage of the cylindrical member, and then passes through the magnet assembly inner periphery oil passage and the magnet assembly outer periphery oil passage. It passes through the oil passage on the upstream side of the two, and then flows into the magnetic field forming oil passage formed between the adjacent ends of the two sets of permanent magnets.

In this case, since the two permanent magnet sets are each constructed by connecting comrades of different polarity with magnetic force, the overall magnetic field of one permanent magnet set is between one end of the permanent magnet set and the other end of the permanent magnet set. Moreover, since the adjacent ends of the two permanent magnet sets are arranged to have different polarities, the adjacent ends of the two permanent magnet sets The magnetic field forming oil passage formed between the parts includes
An extremely strong magnetic field will be generated. When the fuel oil passes through this magnetic field forming oil passage, it is subjected to suitable physicochemical effects by the strong magnetic field. Furthermore, since each of the permanent magnets constituting the two sets of permanent magnet papers is an anisotropic sintered magnet containing neodymium, iron, and boron as main components, their magnetizing force or maximum magnetizing energy product is It is large, has a low specific gravity, and has excellent bending strength. Therefore, even if a small and small number of permanent magnets are used, a sufficiently large magnetic field is generated in the magnetic field forming oil passage, and the fuel The desired physicochemical changes will occur in the oil.

After the fuel oil passes through this magnetic field forming oil passage,
The fuel oil passes through the downstream oil passage of the magnet assembly inner circumferential oil passage and the magnet assembly outer circumference oil passage, and is then discharged from the fuel oil discharge passage communicating with the oil passage to the internal combustion engine. is supplied to
