FUEL-ECONOMIZER

AND ENVIRONMEN'AL PROTECTION Our Ref 428594 POF Code: 63624/266264 The following statement is a full description of this invention, including the best method of performing it known to applicant(s): -1- 0 -1A- A High Efficiency and Environmental Protection Fuel Economizer The invention relates to an internal combustion engine, more particularly, to a magnetization fuel economizing device for automobile fuel engine.

In order to reduce the fuel consumption to improve combustion, there exists a method for fuel magnetization. This method causes the fuel to flow through a magnetization device for fuel so as to improve the dispersed property and atomization level of the fuel which will bring about the fuel to combust sufficiently, thus to realize the aim of fuel saving.

The utility model No.ZL9220 6719.8 discloses a double cavity magnetization fuel economizer shown as Fig. 1, which has a through cavity along the longitudinal direction of the aluminium alloy housing of the fuel economizer and the through cavity has its two ends to join with respectively threaded connection, tube connectors. Arranged in the housing is a magnetization cavity connected vertically with the longitudinal through cavity with two cylindrical permanent magnets in the magnetization cavity. In addition, there is a magnetic filter cavity with a cylindrical permanent magnet in it. After the two permanent magnets are loaded in the magnetization cavity with their N poles opposed each other, the upper end of magnetization cavity is sealed with S: 20 a cylindrical block. The advantage of this utility model is that the permanent magnets have a higher magnetic energy product and a higher inherent o:i coercitive force, which will cause fuel to combust sufficiently and to increase the output power of the engine through forming a stronger magnetization effect without having to be superimposed by a static electrical field. Meanwhile, the 25 contents of carbon monoxide and hydrocarbons reduce, and the iron magnetic materials in the fuel will be less accumulated in the magnetic filter cavity by means of the adsorption of the magnet in this cavity.

However, in this utility model, the arrangement of these permanent magnets can not form a closed magnetic circuit, which will influence the intensity of the magnetic field. Therefore, there still exists a need to further increase the intensity of magnetic field so as to improve the magnetization for the fuel.

CWWRO M 4239-91OG M r o iE i_ -2- An objec+ of the invention is to provide a new structure of the magnetization fuel economizer to improve the above mentioned structure.

It would be useful to provide a new magnetization fuel economizer which can form a closed magnetic circuit in the fuel economizer, thus to increase the magnetic field intensity and to further improve the magnetization effect of the fuel with the results that a high combustion efficiency of the fuel can be obtained hence the output power of the engine may be enhanced to realize a fuel saving and a exhaust gas clean up. Furthermore it would be helpful if the magnetic field intensity of the magnetic filter cavity can be increased to such an extent that the iron magnetic materials suspended in the fuel can be totally adsorbed in this cavity and so do not block up the cavity again.

According to an aspect of the present invention there is provided a magnetization fuel economizer for an internal combustion engine, including: a housing having a longitudinal through cavity, a tube connector being hermetically disposed at each of two ends of said through cavity for communication with a fuel supply pipe; a magnetization cavity in the housing substantially perpendicular to the through cavity havinq disposed therein two permanent magnets with their magntic poles ar: .ed spaced apart opposite each other, the interval beween the two permanent magnets forming a fuel passing gap in the through cavity with a width in the range of about 0.5-2.0mm; and a magnetic filter cavity arranged to communicate with the through cavity and being substantially parallel to the magnetization cavity, the magnetic filter cavity having a permanent magnet therein; wherein non-opposed ends of the two permanent magnets in the magnetization cavity are provided respectively with magnetic circuit sheets to form a closed magnetic circuit, and wherein one end of the permanent magnet in the magnetic filter cavity is provided with a magnetic circuit sheet and the S, ,other end of the permanent magnet is arranged spaced from and opposed to a magnet circuit sheet disposed on an opposite surface of the magnetic filter cavity to form a fixed fuel passing gap there-between.

CIWNWORDENNYMSLPECPwG,23g-95 OC -3- In comparison with the prior art, since the present invention provides an application of the fuel economizer of the structure having magnetic circuit sheets, it is possible to form a closed magnetic circuit in the fuel economizer and thereby enhance the instrumental magnetic field intensity and the magnetization efficiency of fuel, to thus realize the aim of fuel saving and exhaust gas clean up.

The above and further features of the present invention will be more fully appreciated from the following detailed description of preferred embodiments of the invention with reference to the accompanying drawings, in which: Fig. 1 is a sectional view of a magnetization fuel economizer according to the prior art; Fig. 2 is a sectional view of the magnetization fuel economizer according to a first embodiment of the invention; Fig. 3 is a vertical view of the magnetization fuel economizer according to the invention; Fig. 4 is a sectional view of the magnetization fuel economizer according to a second embodiment of the invention; and Fig. 5 is a sectional view of the magnetization fuel economizer according 2 to a third embodiment of the invention.

The invention will be described in the following through its embodiments with reference to the accompanying drawings, in which the some part is denoted by the same reference numeral.

As shown in fig. 2, a housing is denoted by the reference numeral 1, which is made of aluminium alloy. The housing 1 has a longitudinal and circular :o 25 through cavity, and the inner walls of the two ends of the cavity are formed with internal threads. The housing 1 has formed in it a magnetic filter cavity and a magnetization cavity, and the two cavities being perpendicular to and in communication with the longitudinal cavity. The two ends of the through cavity 4.4.

4 4 are joined hermetically with tube connectors 13 and 14 respectively. The tube connectors are made of aluminium alloy or brass. The inner flow passage of the tube connecters is shaped at one end to be flared and outwardly expanded RAfor connection with the fuel economizer, and the other end portion of the tube e$ C ORD UENNYMSPECPVWGC34239-.95C C 1. j -4 connector is formed as a straight tube for communication with a fuel supply pipe, a carburettor or a fuel injection pump.

The magnetization cavity is a circular hole with two pern. .,ient magnets 3 and 4 disposed in it with their magnetic poles opposite each other. A fuel passing gap with a width in the range of 0.5 2.0 mm is formed between permanent magnets 3 and 4, which may be located opposite each other with the N pole to N pole, or S pole to S pole, or N pole to S pole. Furthermore, the magnetic circuit sheets 7 and 8 are disposed on the other ends (the nonopposite magnetic poles) of the magnets 3 and 4 respectively, so that a closed magnetic circuit is formed.

The magnetic filter cavity is a stepped hole in communication with both the longitudinal through cavity of the housing 1 and the surface of the housing 1. A permanent magnet 2 is mounted in the magnetic filter cavity with one end of the magnet provided with a magnetic circuit sheet 6 and the other end of the magnet opposed to a magnetic circuit sheet 5 disposed on the undersurface of the magnetic filter cavity, thus to form a closed magnetic circuit. A fixed fuel passing gap is formed between the permanent magnet 2 and the magnetic circuit sheet 5. In this embodiment, the width of the gap is in the range of about 1 5mm, and preferably, 2 3mm. The magnetic circuit sheet 5 is mounted in 20 a recess of the housing on the bottom of the magnetic filter cavity which may be realized through a shrink fit and a compression bonding of an industrial gelatin.

Since the magnetic circuit sheets of the aforesaid type are applied in the magnetization cavity and the magnetic filter cavity, closed circuits of high intensity magnetic field are formed, which enhance greatly the magnetization 25 effect of the fuel in the fuel circuit and achieve a notable effect of fuel saving and exhaust gas clean-up.

In this embodiment, the permanent magnets 2, 3 and 4 are made as cylindrical bodies from a material of NF30 with diameters and heights all in the range from 6mm to 80mm. The inherent coercive force of the permanent 30 magnet is in the range of 18000 20000 oersteds. After magnetizing by means of a conventional art, the magnetic field intensity of the N pool face is in i the range from 4000 to 5200 Gauss.

it~ C~:aNIWOROJENNYMSPECPWG4239-5.DOC u In this embodiment, magnetic circuit sheets 5, 6, 7, and 8 are in shapes of circular disk or cylindet with diameters from 6 to 80mm and thicknesses from 0.3 to 10mm, and all can be made from magnet conductance material such as iron DT4 of the industrial purity level or silicon steel sheet.

During the operation of a fuel engine, the fuel passes through the fuel supply pipe into 'he double cavity magnetization fuel economizer. When the fuel flows through the fuel passing gap formed between the permanent magnet 2 and the magnetic circuit sheet 5 on the bottom of the magnetic filter cavity, the area passed by the fuel flow changes abruptly, and the flow rate of fuel changes suddenly from slow to fast, thus the fuel flow forms substantially as a turbulence. The molecular group structures of the fuel in this turbulent state are in collision and friction with each other, and change from a relative stable state to a metastable state under the influence of molecular Brownian movement.

Under the action of premagnetization of the closed magnetic circuit formed by the permanent magnet 2 in the magnet filter cavity with magnetic circuit sheets and 6, the molecular groups under metastable state are partially broken up with the fuel particulates tending to be finer and dispersed. Meanwhile the iron magnetic particles suspended in the fuel are adsorbed totally on the permanent magnet 2, which purifies the fuel. The fuel flowing out from the above mentioned fuel passing gap moves through the longitudinal through cavity of the housing into the fuel passing gap formed between the permanent magnet 3 and 4 of which their magnet poles are opposed each other. Now, the area *S passed by fuel flow in this gap changes from small to big, and again suddenly becomes very small, and the fuel which has been in a high speed turbulent 25 state is again influenced intensively by a high density magnetic force line in the closed magnetic circuit formed by permanent magnets 3 and 4 as well as a magnetic circuit sheets 7 and 8, thus the molecular groups of metastable state are further broken up massively. The viscosity and density of the fuel are S reduced, the fuel particulates become smaller and more easily dispersed, the a 30 level of fuel atomization is enhanced and the conditions for fuel to combine with oxygen are improved remarkably, so that the fuel can be combusted more C: WINWORDENNYMSPECPWt4.239-25.COC II -6 completely. In this way the output power of the engine can be enhanced and the exhaust gas is cleaned up.

During assembly, the magnetic circuit sheets 7 and 8 are first attached respectively on the other ends (ie. the non-opposed poles) of permanent magnets 3 and 4, then the permanent magnets 3 and 4 are disposed in the magrnetization cavity, a round block 10 is fixed on the magnetization cavity and sealed through an adhesive to prevent from leakage. The fuel passing gap between permanent magnets 3 and 4 should have a width in the range of 0.5 The tube connectors 13 and 14 are mounted on the housing, then the magnetic circuit sheet 5 is compression bonded through a shrink fit in the recess on the bottom of the magnetic filter cavity. The diameter of magnetic circuit sheet 5 should be less about 1mm than that of the permanent magnet 2.

Then, the permanent magnet 2 is inserted into the magnetic filter cavity, so that a pole opposes to the magnetic circuit sheet 5, and a step restricts the magnet 2 in a certain position such that the fuel passing gap between magnetic circuit sheet 5 and the magnetic pole is of a width preferably in the range of 2-3mm. Finally, a cavity cover 9 is screwed down to seal and to bond the cover.

When the magnetization fuel economizer according to the invention is mounted on an engine, the connection position are some what different ",!depending on the kind of engine. When it is mounted on a gasoline engine, the fuel inlet is connected with a fuel supply pipe of a gasoline pump, and the fuel outlet is connected with a carburettor and is preferably mounted directly on the carburettor. When it is mounted on a diesel engine, the fuel inlet is connected 25 with the fuel outlet tube of the filter, and the fuel outlet is connected with the fuel ;injection pump and is preferably mounted directly on the fuel inlet of the fuel injection pump.

Fig. 4 and 5 show respectively the second and third embodiments 1 4 according to the invention. They are multi fuel circuit fuel economizers respectively, and are suitable for large internal engines of large tonnages automobiles, tractors, locomotives and ships.

IK~ N C~\MloRDUEfu~sPeCPWC3423-5OC -7- Fig. 4 shows a multi cavity magnetization fuel economizer, which has in its longitudinal through cavity disposed three or more magnetization cavities arranged vertically, and parallel with each other. In these cavities there are many pairs of permanent magnats with magnetic circuit sheets. The arrangements of permanent magnets and magnetic circuit sheets are the same as in embodiment 1. To dispose many pairs of permanent magnets in the device provides for repeated magnetization of the fuel to increase the magnetization effect.

Fig. 5 shows a multi fuel circuit magnetization fuel economnzer. There are arranged a plurality of parallel through cavities along the longitudinal direction in the housing of the economizer. Each end of the through cavities is connected with a common inlet and outlet tube connector of the fuel tube and each through cavity has many pairs of permanent magnet with magnetic circuit sheets arranged as in the second embodiment. This kind of fuel economizer is especially for the magnetization of fuel in large internal combustion engines.

The applicatiuri of intensified two or more stages magnetization 25 process has a superposition effect, which may sufficiently develop the magnetization effect of high magnetic energy product and high magnetic field .00 Cintensity of permanent magnets to the fuel so as to render a further fuel saving and a reduction of the emission of harmful substances. The experiments and practices show that by the invention, a fuel saving rate of 10%-25% may re realized; CO and HO reduces respectively 20%-80% with Co reducing 35% in average and reducing 80% at maximum, HO reducing 30% in average and reducing 80% at maximnum; and the smoke density reduces over Li~.
