For example, gasoline is a mixture of hundreds of hydrocarbon substances distillated at a temperature between 30°-220° and various additives such as a cleaning agent, a defoaming agent, and an antifreezing solution. The gasoline is injected into a cylinder by the fuel supply apparatuses and then ignited. Not every substances in the gasoline is combusted at the same time in the cylinder. The substances of the gasoline is continuously combusted while they travel to a muffler through an exhaust manifold.

Thus, the efficiency of fuel converted to kinetic energy of a piston is actually about 30% of the entire fuel.

To solve this problem, technologies to use liquefied petroleum gas or natural gas in a gas state which exhibits a high combustion efficiency as fuel by modifying gasoline engines and diesel engines have been developed and commercialized.

As the conventional technologies to solve the above problem, there are methods of installing metal exhibiting a magnetic force or a metal catalyst at a fuel supply hose, and an apparatus helping mixture of air and fuel at air and fuel intake portions, and a method of electronically controlling a fuel injection apparatus by detecting the amount of exhaust oxygen, the frequencies of rotation of an engine, or an idle state.

Nevertheless, since the above methods fail to show remarkable results, a further continuous improvement is needed.

FIG. 1A is a model view illustrating the structure of the present invention. FIG. 1 B is a block diagram showing the position and structural elements of the present invention.

The present invention as shown in FIG. 1 includes an ion generating apparatus 300, a heating apparatus 200, and a meal catalyst

apparatus 100. The ion generating apparatus 300 applies negative charges to fuel mixed with air. The heating apparatus 200 generates heat using external electric power. The metal catalyst apparatus 100 includes a metal catalyst to increase an internal chemical reaction speed in the present invention.

FIG. 2 is an exploded perspective view illustrating a detailed structure of the present invention. As shown in FIG. 2, in the present invention, the ion generating apparatus 300, the heating apparatus 200, and the metal catalyst apparatus 100 are included in a cylindrical main body 400.

The main body 400 is made of ceramic exhibiting superior insulation and heat resistance features or special plastic material. The main body 400 may be a structure made of metal exhibiting high conductivity and heat resistance and insulated by closely pressing an insulation cylinder 430 inside.

The heating apparatus 200 and the metal catalyst apparatus 100 which are disc type or circular structures are inserted in the main body 400. After the insertion, an end portion of the cylinder is formed as an inward flange to facilitate coupling and accommodation and a coupling mean for coupling the cylinder 10 and the fuel supply apparatus 20 are coupled is preferably formed. Although the coupling means is not shown in the drawings, it is general that a thread is formed on an outer circumferential surface to be screw coupled.

Also, the main body 400 is preferably provided with a cap 420 screw coupled to the main body 400 so that internal elements are easily accommodated and assembled.

The ion generating apparatus 300 includes a needle type electron generating portion 310 inserted in the main body 400 through holes 330 and 333 formed in the main body 400, an insulation pipe 320 inserted

around the electron generating portion 310 and inserted in the holes 330 and 333 of the main body 400 and the insulation cylinder 430, and a high voltage DC power supplier 50 inputting the cathode to the insulation pipe 320 insulating the main body 400 and the electron generating portion 310 and the electron generating portion 310 and connecting the anode and the main body 400 to apply a high voltage DC.

Although, in FIGS. 2 and 4, a need is used as the electron generating portion 310 of the ion generating apparatus 300, the technical concept of the present invention is not limited to the above embodiment.

It is preferred to form the electron generating portion in a disk type wire net and inserted in the main body 400 and then power is applied to supply negative charges in a path for the fuel mixed with air.

The high voltage DC power supplier 50 preferably uses a battery power for a car by converting the voltage thereof. Since a high voltage DC converter used therefor is a well known technology and already commercialized and further not the gist of the present invention, a description thereof will be omitted.

The output of the high voltage DC supplier 50 is preferably about 5, 000-100, 000 Volts.

In the present embodiment, the electron generating portion 310 is formed as a needle type. The needle type electron generating portion 310 is preferably made of a material which is not easily oxidized and has a high conductivity. The needle type electron generating portion 310 is inserted in the main body 400 by being insulated from the main body 400 by the insulation pipe 320 and installed perpendicular to the flow of the fuel mixed with air.

The ion generating apparatus 300 grounds the anode of the main body 400 and insulates the cathode of the electron generating portion 310, so that electrons generated by the electron generating portion 310

are derived to be coupled to the fuel mixed with air.

That is, in the above structure, when a high voltage DC power is applied to the ion generating apparatus 300, discharge like natural discharge (lightening) is generated and a discharge phenomenon ionizes surrounding air and fuel.

The ionization of air due to the discharge phenomenon is the same principle adopted in an anion generating apparatus used in air cleaners.

The heating apparatus 200 will be descried in detail with reference to the drawings.

As shown in FIGS. 2 and 3, the heating apparatus 200 includes a heating disk 220, a fixed disk ring 210, a support disk ring 230, an electric connection means 250, and a DC power supplier 40.

The heating disk 220 is provided in multiple numbers deposited in the main body and a honeycomb type structure made of barium (Ba) or titanium (Ti) or an alloy thereof. The honeycomb type structure of the heating disk 220 makes the fuel mixed with air incoming from an inlet of the main body easily pass therethrough.

The fixed disk ring 210 is inserted between the heating disks 220 in the main body 400 and made of a metal conductive body having a circular structure supporting the heating disks 220 at both ends of the heating disks 220.

A support body 213 circularly protrudes in the middle and along an inner circumferential surface of the fixed disk ring 210 to form a"-L" shaped sectional structure. The fixed disk ring 210 and the heating disk 220 are alternately deposited. The alternate deposition means a structure in which the fixed disk ring 210 is inserted between the heating disks 220 and deposited thereon.

The outer circumferential surface of the fixed disk ring 210 is

accommodated on the inner circumferential surface the heating disk 220.

The heating disk 220 has a thickness such that the fixed disk rings 210 at both ends of the heating disk 220 do not contact each other. The outer circumferential surface of the heating disk 220 is supported by the support body 213 of the fixed disk ring 210 so that the heating disks 220 at either end do not contact each other.

Two electrode holes 251 and a plurality of fixing holes 211 are formed in the fixed disk ring 210. A hole 254 for electrode connection which is a female screw and connected to one of the electrode holes 251 is formed at the outer circumferential surface of the fixed disk ring 210.

A support disk ring 230 is a circular structure disposed at one end portion of the alternating deposition structure of the fixed disk ring 210 and the heating disk 220. A female screw 231 is formed in the support disk ring 230 in a consecutive line with the fixing hole 211 of the fixed disk ring 210. The alternating deposition structure of the fixed disk ring 210 and the heating disk 220 is coupled by the support disk rig 230 and a disk fixing screw 215.

In the disk fixing screw 215, one end portion of a rod 215-b where a male screw is formed on an outer circumferential thereof passes through the fixing holes 211 of the fixed disk ring 210 and is coupled to the female screw 231 of the support disk ring 230. A portion of the disk fixing screw 215 inserted in the fixed disk ring 210 is insulated from the fixed disk ring 210 by inserting an insulation pipe 215-a around the above portion. An insulation washer is inserted around the other portion of the disk fixing screw 215 to be insulated from the fixed disk ring 210 and a spring 215-c and a nut 215-d are inserted therearound.

The alternating deposition structure of the fixed disk ring 210 and the heating disk 220 is screwed and coupled by the disk fixing screw 215 and the support disk ring 230. The spring 215-c provides a

predetermined coupling force and absorbing thermal expansion stress when the alternating deposition structure expands due to heat.

Electric power having different polarities is alternately applied by the electric connection means 250 to the fixed disk rings 210. The electric connection mean 250 is inserted in the electrode hole 251 of the fixed disk ring 210. Each wire penetrates the fixed disk ring 210 and alternately connects the fixed disk ring 210.

FIGS. 2 and 5 shows in detail the electric connection means which is inserted in the electrode hole 251-a of the fixed disk rings 210 and alternately coupled to the fixed disk rings 210-a and 210-c by a screw 255 coupled to the hole 254 for electrode connection, and including a positive electrode 250-a insulated by inserting the insulation tube 253 in the electrode hole and provided at the fixed disk rings 210-b and 210-d which are not coupled and a negative electrode 250-b inserted in the other electrode holes 251-b of the fixed disk rings 210, alternately connected to the fixed disk rings 210-b and 210-d of the fixed disk rings to which the positive electrode is not connected, and insulated from the fixed disk rings 210-a and 210-c connected to the positive electrode by the connection tube 253.

As shown in FIGS. 2 and 5, the electric connection means 250 and the fixed disk ring 210 are coupled by screwing the screw 255 into the hole 254 for electrode connection of the fixed disk ring 210.

That is, the electric connection means 250 and the fixed disk ring 210 are coupled by separately and alternately arranging the fixed disk rings 210-a and 210-c to which the positive electrode is connected and the fixed disk rings 210-b and 210-d to which the negative electrode is connected.

Thus, when DC power of different polarities is applied to the electric connection means 250, the fixed disk ring 210 applies electric

power of different polarities to the both ends of the heating disk 220.

FIG. 5 is a sectional view and an equivalent circuit diagram showing the electric connection means 250 applying to the heating disk 220 and the fixed disk ring 210 are coupled.

As shown in FIG. 5, the heating disk 220 is equivalent to three resistors in parallel connection, and joule heat is generated by the DC power supplier 40.

The heat capacity of the generated joule heat is determined by the material of the heating disk 220. In the present invention, the heating disk 220 is made of a metal body formed of barium (Ba), titanium (Ti), or an alloy thereof.

Accordingly, when a car battery is used as the DC power supplier 40, heat having a temperature between 370°C-480°C is generated in the heating disk 220.

The fuel mixed with air passing through the heating apparatus 200 is in a low pressure state in the main body by the cylinder of the engine and is not exploded in the main body by a fast supply speed.

In the preferred embodiment shown in FIG. 5, the heating apparatus having three heating disks is shown together with an equivalent circuit. However, the present invention is not limited to the above number of the heating disks and the numbers of the heating disks and the fixed disk rings can vary according to the capacity of the internal combustion engine.

The metal catalyst apparatus 100 is a honeycomb type sponge disk having a gauze or fine ventilation structure which is made of each of ruthenium (Ru), rhodium (Rh), palladium (Pd), Osmium (Os), and platinum (Pt), or an alloy thereof.

The metal catalyst apparatus 100 is inserted in the main body.

Although in the preferred embodiment the metal catalyst apparatus 100

is inserted between the fixed disk ring 210 and the support disk ring 230 of the heating apparatus 200, the present invention is not limited to the order of insertion.

In the present preferred embodiment, the metal catalyst apparatus 100 is formed as a honeycomb sponge disk having an outer diameter such as the fixed disk ring 210. A hole 411 is formed in the disk surface in line with the fixing hole 211 formed in the fixed disk ring 210. the disk fixing screw 215 penetrates the hole 411 and coupled to the support disk ring 230 at the rear end.

When the temperature of gas fuel passing through the metal catalyst apparatus 100 is higher than 300°C, a catalyst action begins.

Since the above temperature is provided by the heating disk 220, when the fuel mixed with air passing through the heating apparatus 200 and the ion generating apparatus 300 are derived by the metal catalyst to have a chemical reaction and sucked into the cylinder, an efficiency of electrochemical reaction increases.

When the ion generating apparatus 300, the heating apparatus 200, and the metal catalyst apparatus 100 are inserted in the main body 400, since the support disk ring 230 can be electrically connected to the inward flange portion of the main body, in the case of forming the main body as an inwardly flanged cylinder, an insulation disk ring 240 is preferably inserted between the main body and the support disk ring 230 to insulate them.

The function and operation of the present invention will now be described.

Since gasoline or light oil used as fuel for internal combustion engines is a mixture of numerous substances, it is difficult to explain every chemical changes. Accordingly, typical chemical reactions generating in the present invention will be described.

The ion generating apparatus ionizes fuel mixed with air and derives chemical reactions by applying negatrons to the fuel mixed with air sucked into the cylinder of the engine, which is a phenomenon like a sort of natural lightening.

In particular, since ozone (03) generated in this step exhibits a very high oxidation degree than oxygen O2, ozone takes an important role in combustion.

Typical chemical reaction formulae are shown below. <BR> <BR> <BR> <BR> <BR> <BR> <BR> <P> O2+O2+O2#O3+O3<BR> <BR> <BR> <BR> <BR> <BR> <BR> O2#(O2)-<BR> <BR> <BR> <BR> <BR> <BR> <BR> CnH2n+2#(CnH2n+2)-<BR> <BR> <BR> <BR> <BR> <BR> <BR> H20 o (H20) The heating apparatus is a sort of an oil refining process and pyrolyzes long chain hydrocarbon based substances into short chain hydrocarbon based substances such as methane, ethane, propane, and butane based substances.

In addition, as a sort of preliminary combustion step, the hydrocarbon based substances are changed to aldehyde (R-CHO), alcohol (R-OH), keyton (R-CO-R), carbon oxide (CO), and alkyl radical (R-).

Typical chemical reaction formulae are shown below. <BR> <BR> <BR> <BR> <BR> <BR> <BR> <P> CnH2n+2---o 2Cn/2H (2n+2)/2<BR> <BR> <BR> <BR> <BR> <BR> <BR> CnH2n+2--------- CnH-x + XH CnH2n+2#Cn-xH(2n+2)-3x+ XCH3 <BR> <BR> <BR> CnH2n+2+O2#CnH2n+H2O2<BR> <BR> <BR> <BR> <BR> <BR> <BR> CnH2n+2+O#CnH2n+1+OH

The metal catalyst lowers activation energy of internal chemical reactions of the present invention. In particular, a metal catalyst of a platinum (Pt) base characteristically oxidizes or hydrogenizes a synthesized substance by changing the configuration thereof while it absorbs and discharges the substance, particularly, hydrogen.

In particular, the metal catalyst facilitates reactions of cycloalkein, alkin (C=C), or alkain (C=C) based hydrocarbon family to be changed to alkein (C-C) based hydrocarbon family.

Typical chemical reaction formulae are shown below. <BR> <BR> <P> CnH2n+H2#CnH2n+2<BR> HC-CH + 2H2 o C2H6<BR> CO + 0-)-CO Thus, the fuel mixed with air injected into the cylinder of the engine after passing the present invention, which is a compound exhibiting a high octane number such as oxygen family (O, O@ 02, °2-7 and 03), hydrogen family (H, H-, and H2), carbon oxide family (CO, CO-, and CO2), hydroxide family (OH and OH-) and alcohol family (R-OH), and carbon family (C and Cx) and hydrocarbon family (CHx, C2Hx, C3Hx, and C4Hx), which are generated by a complicated chemical reactions, is changed to a sort of synthesized natural gas. In particular, ozone (O3), hydrogen (H2), and alcohol (R-OH) generated during this process are important in increasing an efficiency of combustion.

Industrial Applicability As described above, the fuel saving device for an internal combustion engine according to the present invention is inserted

between the carburetor and the cylinder of the internal combustion engine and processes the fuel mixed with air sucked into the cylinder to have a high combustion efficiency. Thus, combustion close to a complete combustion is generated in the cylinder of the engine so that consumed fuel is reduced.

Also, due to the complete combustion, generation of toxic gas such as carbon monoxide or hydrocarbon is reduced.
