METHGDS AND APPARATUS FR MlXllNG FLUllBS Bo (Carl Gsta Nyman, Tyrese, Sweden, assigner to Alwae international, line., Bahamas, British W est Endies, a corporation of Panama Filed 4l, 196i), Ser. No. 330 17 Claims. (til. 12E-M9) This invention relates to method and apparatus for mixing fluids, and more particularly involves a mixing chamber that may be used in many mixing applications sucn as internal combustion engines of the reciprocating piston, gas turbine, turbojet and jet types, and in chemical processes, and for the generation of large volumes of gases for heating and generation of ionic winds and the like.
To obtain a thorough mixing of a rst medium, eg., combustive, but with a second medium, eg., combustible, in a mixing chamber for eventual combustion, it is indispensable that some kind of turbulence be created in the iluid within the chamber. In known combustion chambers, turbulence in the fluid is conventionally created by one or more obstacles, either rigid or constituted by jets of an auxiliary fluid. These obstacles have the inherent disadvantage of creating zones where the fluid is not in proper circulation and thereby results in a loss of energy. The application of the present invention to con bustion chambers, such as for example those used in internal combustion engines and as hereafter described is advantageous in that it aids in the proper mixing of the gases, the elimination of pulsations and noise and relatively clean combustion.
The improved results obtained by my present invention are attributable in large part to the ionization of gases and gaseous mixtures to increase their volume, the efficiency of reaction and hence their conversion into energy. I have discovered that the efficiency of fuel consumption and power produced for the development of energy is greatly improved by ionization which may result in dissociation of gaseous fuel mixtures under controlled conditions of temperature aud pressure.
ln general, my improved methods comprise a step of ionizing the air-fuel mixture, either prior to ignition or in the combustion chamber to thereby increase the volume of the products of combustion, their velocity away from the Zone of ignition, and the efhcency of mixing and combustion with the concomitant development of reduced pressures for the creation of a strong intake suction of the air-fuel mixture into the combustion zone after initiation of combustion. rhe resulting increase in efficiency of reactivity, energy release, gaseous thrust development, control and economy are marked, unexpected and surprising.
The benefits of my present invention can be realized to a substantial degree in many conventional types of internal combustion engines, oil burning combustion charnbers and like by the addition of ionizing equipment at or in advance of the ignition zone to increase the volume and velocity of burning fuel mixture as well as the homogeneity of the air-fuel mixture. A further essential novel element or" my present discovery is the utilization of a magnetic stabilizing field at the ionizing zone (the ionizing effect occurring at relatively low voltages) to control the ion flow pattern for maximum utilization.
Various prior efforts have been made to utilize ionization to increase reactivity of gases and vapors, but so far as I ain aware, the prior efforts have not gone into substantial commercial use. ln United States Patents No. 2,583,898 and 2,766,582 various proposals have been made where ionization is effected in the absence of magnetic fields and with ionizing potentials of at least 400 Bgllhzdd Patented Nov. l2, i963 ICC volts or higher. ln the United States Patent No. 2,766,- 582, ionization of a dielectric type fuel prior to vaporization is disclosed. My invention differs from such prior efforts in ionizing the mixture to be reacted in the gaseous or vapor phase, by utilization of a magnetic field, with ionizing potentials preferably of the order of from about 6 to 120 volts, depending upon the size of the equipment used and the mixtures to be reacted, and in certain applications under high temperature and subatmospheric pressures. While higher voltages may be used, optimum results have been secured with mixtures so far reacted with relatively low voltages and little if any change is noted by the application of much higher voltages. While I am aware that magnetic elds have been utilized in the ionization and dissociation of gases in equipment such as Phillips vacuum and pressure meters, and in cyclotrons, I am not aware of any use of a magnetic field to increase reactive eliciency of gaseous mixtures.
The primary object of my invention is to provide novel methods and apparatus for the ionization and utilization of gases, gaseous mixtures, vapors and the like.
Another primary object of this invention is to provide novel methods and apparatus for the improvement of chemical reactivity' of gaseous and vapor phase mixtures.
A further object of the present invention is the improvement of efliciencies and simplilication of equipment for the development of heat energy and thrust from fuel in heat engines, internal combustion engines and fuel burners of well-known types and common use.
Still a further object of this invention is to provide method and means for ionizing the gaseous combustile mixture in the presence of the magnetic field either in a fuel mixing chamber prior to ignition of the mixture or in the combustion chamber.
Other detailed objects of my invention will be apparent from the foregoing general and the following detailed descriptions, from the claims, and from the appended drawings, wherein:

FIGURE 7 is a view in section similar to FIGURE 6 and which is provided with a series of separate ionizing stages and magnetic iields along the combustion chamber;
FGURE 8 is a longitudinal side elevation view in section of a conventional ram jet engine modified in accordance with the present invention to provide improved mixing of the air and fuel prior to combustion;
FIGURE SA is a partial end view of the lower pair of electrodes taken along lines A-A in FIGURE 8; and
FIGURE 9 is a longitudinal side View in elevation in section of a conventional turbojet modified in accordance with the present invention to provide one or more pairs of ionizing terminals and magnetic fields for acting upon the fuel-air mixture in the combustion chamber.
Referring now to FIGURES l and 2, the invention relates to an air-fuel mixing or combustion chamber itl having tubes 12 which serve as means through which a liquid or gaseous fuel is fed into chamber iii for mixing with an oxidizing element, such as air, that is supplied to the left hand side of chamber i@ as viewed in FIG- URE 1 through suitable valve means I4. In accordance with the present invention, a superior atomization and mixture of the fuel and air is provided by applying an ionizing potential through electrodes 20 and 22 which extend through the walls of chamber and the thoroughness of this mixture is further enhanced by application of a magnetic field at or near the place of ionization as by permanent magnets 24 and 26. The direction of the magnetic eld is perpendicular to the current path between electrodes Ztl and 22 of chamber it?.
The homogeneous diffusion or mixture of the fuel 'and air, which results in improved output through higher combustion efficiency of the fuel in an internal combustion engine or burner as will be described in greater detail below, is effected by first converting the particles or molecules in chamber l@ into charged ions at the region adjacent terminals Ztl and 22. It appears that some dissociation of the molecules may occur. As the charged particles pass through the magnetic field supplied by magnets 24 and 26 along chamber it) toward the region of low pressure as combustion takes place, there is induced in such charged ions or particles, a component of force resulting in movement of the charged particles in a direction perpendicular to the axial ilow of the airfuel mixture along chamber 10. The negatively charged particles and positively charged particles are deflected in opposite directions when moving through the magnetic field in a manner analogous to the movement of electrical charges in a conductor cutting the flux lines of a magnetic field in a dynamo which generates an electrical potential.
The walls of chamber 16 accordingly are made of nonmagnetic materials, such as aluminum, or an insulating non-conducting plastic material, such as for example polyethylene or of a heat resistant, non-magnetic insulating material such as non-magnetic stainless steel where combustion takes place in chamber 10. The permanent magnets 24 and 25 may be a ferrite and polarized as shown in FIGURE 2 to provide a sutiicient magnetic field across chamber 1t). VJhile various configurations of permanent magnets may be used to provide a magnetic field across chamber 1i), I have found that the use of a pair of arcuately shaped magnets having the inner arcuate surface and the outer arcuate surface polarized in opposite directions as arked in FIGURE 2 is sufficient to materially improve the air-fuel mixture and the resulting efficiency of combustion.
Magnetic rubber, as developed by the Goodyear Company, may also be used by wrapping around and along the full length chamber lil, which it serves as a pre-ignition ionizing section and the temperatures are not too high, to advantage.
Electrodes 2li: and 22 are made of a suitable conducting material that is not corrosive, such as copper or brass, and are preferably mounted through the walls of chamer l@ in such a manner as to be sealed and to be insulated from one another. If the walls of chamber l@ are electrically conductive, then insulation bushing 28 or rubber or like material is used around at least one of the electrodes 20.
The magnitude of the voltage applied to electrodes 20 and 22 depends upon the spacing between the electrodes.
With a spacing of about 50 millimeters, voltages on the order of from 5 to 100 or 200 volts are satisfactory for effecting ionization of the air-fuel mixture. In practice, I have found that 40 volts D C. produces Satisfactory ionization and that little or no increase in eiiiciency results from the application of higher voltages, or from the use of an alternating voltage. A battery 3@ or other conventional source of D.C. voltage and variable resistor 3l may be used to supply the ionizing potential to electrodes 20 and 22.
The fuel and air mixing techniques discussed above may be used in conjunction with internal combustion engines of several types. For example, in FIGURE 3 block 32 may be part of an L-head type reciprocating piston engine having spark plug 34 may be generally of the type as illustrated in United States Patent No. 2,563,939. Each cylinder has an inlet port 35 and individual right angle pipe elbows 33 cast integrally with header filly/hielt extends longitudinally of the engine. Header 4t) isprovided with an inlet 42 which extends upwardly therefrom at the central portion of the manifoldvheader 49 and is adapted to receive upon its upper end the usual form of air cleaner 43. In this embodiment, the fuel line is shown connected to a fuel feed tube 44, the end of which injects the fuel with the air at the region of electrodes 2t? and 22, which are encompassed by the magnetic ield supplied by the magnets as shown in FIG- URES 1 and 2, magnet 24 only being illustrated in FIP- URE 3. The mixing of fuel and air takes place not only by the usual turbulence, but the foregoing arrangement of parts is effective to produce the improved mixture of fuel and air with the resulting increase in the engine output due to improved efficiency of combustion.
In FIGURE 4 a similar arrangement is shown for feeding the air-fuel mixture to the fuel input manifold of and over-head valve type engine comprising a cylinder Sil having piston 52. In this embodiment the fuel inlet chamber 42 contains the electrical terminals 2l) and 22 across which the ionizing potential is provided at the region of the magnetic field provided by the magnets, only magnet 2.4 being shown in FIGURE 4. Fuel is supplied through fuel feed tube 44 and air from air cleaner 43 in a conventional manner.
FIGURE 5 shows an embodiment of an internal combastion engine having the usual carburetor 62 for effecting the original air-fuel mixture and an intake duct 6i) between carburetor 62 and a cylinder head having valve 64 and spark plug 66. Tube 60 is preferably formed of two or more telescoping sections 67 and 63 to be variable in length and the tube length is varied until the engine shows maximum performance. Such tubes in ordinary automobile engines should have a length in the range of from 25 to 45 inches between carburetor 62 and the intake valve 64.
A separate pair of ionizing electrodes 2t) and 22 are mounted in each of tubes `67 and 68. In tube 68, the orientation of the electrodes Ztl and 22 and the magnetic field are rotated 96 from the position of the correponding parts in tube e6. This orientation has the effect of more completely mixing the ionized particles to aid further in effecting a complete mixture of the fuel and air. By displacing the two sets of electrodes and magnetic fields with respect to each other, the stream of air and fuel molecules passing along tube 63 at a position to be least affected by the ionizing potential will be in the maximum electric field provided by the terminals in tube 67.
With tubes or the foregoing length, it is preferable to provide more than one magnetic field since each time ionized or electrically charged particles pass through a` magnetic field, additional mixing is provided. As ionization may be neutralized through the recombination of oppositely charged particles as the air-fuel mixture passes through duct 6i? and to effect a more complete ionization and possibly dissociation prior to combustion, it is f positions along the combustion chamber 7d.
D desirable to place la second pair of ionizing electrodes downstream from the carburetor in tube 67 to eect a re-ionization of the air-fuel mixture before it passes through the downstream magnetic iield.
The purpose of using a long duct 6@ of variable length is to lgain the advantage of the added pressure in duct o@ due to a reflected wave which will give a pulse of pressure above atmospheric, and `a deiinite super charging effect on power and torque, Where the total length of the intake duct is selected to get the pressure wave to the cylinder when the piston is at the end of the suction stroke. Such an arrangement results in optimum output from the engine due to a combination of a thoroughly mixed air-fuel mix-ture and to the Iadded pressure in the piston due to the reflected wave through duct ntl.
In each of the embodiments of 3, l and 5, electrodes 2li and Z2 are obviously electrically insulated from one another as explained in connection with `ElGURllS l and 2, and the walls must ,be of a non-magnetic material `as described above to provide a magnetic field across the mixing chamber.
ln FIGURES 6 and 7, two embodiments lof the present invention are illustrated wherein the ionization potential and magnetic field are :applied either in the combustion chamber or at the position where combustion of the fuel-air mixture is initiated.
Considering FIGURE 6 irst, the mixing or combustion chamber Walls '79, which are preferably of a nonconducting, non-magnetic material are closed at the upstream end by a hemispherical section i2 through which fuel injection tube 74 and air supply tubes 76 and 78 are mounted. ionizing electrodes Ztl and 22 are of identical constluction to that shown in FlGURE l and, if the material of wall 7@ is an electrically conducting material, at least one of the terminales 2i? or 22 must be insulated `from wall 7. Permanent magnet 24 is the only magnet shown in this embodiment, magnet Z6 being also present to provide a magnetic field across the mixing chamber at the region of the ionizing terminals 2li and 22 to effect a mixing of the fuel from nozzle 74 `and air from tubes '76 and 78. Suitable means for producing an ignition spark such as spark plug il@ may be provided in walls 7l) of the mixing chamber upstream of the ionizing terminals and magnetic field to thereby initiate combustion of the fuel and air mixture. A suitable nozzle, such for example as that shown in United States Patent No. 2,538,460 to Kaveny, may be provided at the downstream end to adapt this mixing chamber for use with a typical oil fired `furnace whereby the llame, during .operation would be downstream or terminals Ztl and 22, or alternatively the combustion may take place at or about the location of terminals Zd and 22.
In the embodiment of FGURE 7, three pairs of electrodes and separate magnetic fields are provided at spaced Fuel is supplied throuigh tube 7l-l and air is introduced into chamber *7b* through louvres or slotted openings 82. Spark plug Sil is positioned in the hemispherical end wall 72 to cause ignition of the fuel and air mixture. Combustion is initiated at or slightly downstream of the first pair of electrodes 2?) and 22. As combustion continues, the fuel and air mixture is further mixed by the second pair of electrodes Ztl and 22 and by the third pair of electrodes Ztl and 22 :and their respective magnetic fields.
The second pair of electrodes and 22 may be rotated through an angle of 129 relative to the orientation of the first pair of electrodes 2b* and 22 as shown in FIGURE 7 and the third pair of electrodes 2li and Z2 are then rotated through a further 120 to thereby be oriented symmetrically with respect to the yorientation of the iirst two pairs of electrodes. The application or" the ionizing potential along three axes, each rotated 120 with respect to .the other, etects a helical path to the charged particles as they pass through the combustion 6 chamber and also :a more complete ionization of the particles forming the air-fuel mixture.
At the locations oi' each of the three pairs of electrodes, the magnetic field extends across the combustion chamber in a direction perpendicular to the electric lield between the electrodes Ztl and 22, and is provided as by the arcuate magnets 2d and 2.o which are rotated to have the same position relative to their respective electrodes. This has the eiiect of producing a further force on the electrically charged particles as they pass through the combustion chamber 7i? in varying directions to thereby further reduce dead areas ot poor circulation and mixing in the combustion chamber which result in pulsations and poor combustion.
ln one embodiment where l have used multiple tandem magnetic ields and ionizing electrodes, a voltage of about 4t) volts between electrodes Zit and 22 that were about rnrn. apart and a longitudinal spacing between the pairs of ionizing elec todos or approximately 5G mm. were satisfactory. rl`hese dimensions are not critical, but are simply given by way of illustration.
ln vFlGURE 8, a rarnjet is illustrated in longitudinal section, the conventional showing being modified by the addition of the means for providing magnetic field and the ionizing terminals in accordance with the present invention. The generally cylindrical outer shell lilo has an `air entry or nose section liZ and a combustion char ber ldd with a centrally disposed air-fuel mixing chamber lf desired, an air guide cone lill-5 may be used to serve as a compressor. Near the rear portion of air guide cone a `nel ring il@ is provided having nozzles il?. through which fuel is sprayed into mixing chamber At the downstream end of mixing chamber ldd, `a flame holder lle is provided which conventionally serves to hold the leading edge of the llame on the downstream side of flame holder Lilli to prevent the llame from advancing into the mixing chamber lilo.
Because of the relatively large diameter of the air-fuel mixing chamber lilo, it has been found desirable to provide four ionizing electrodes llo, lib, l2@ and i212. Alternate electrodes are connected to the same terminal on the voltage source as indicated in the drawings. Electrodes and l2?, on opposite side walls lill? are infrom one another and preferably from walls lil@ of mixing chamber lilo. Electrodes lid and l2@ are arcuately shaped about center lines i2/l and 126 with opposite ends thereof secured to the outer wall lit@ of mixing chamber lilo, a partial View of the lower pair of electrodes being shown in FlGURE SA. The negative voltage on electrode llZd is supplied through lead lib, which may be supported at one end by air guide cone ldd, and pass through the inside ofthe guide cone as illustrated and to the outside of walls lili) along a support member (not shown) for air guide cone l'r. lonizing electrode lib is connected by lead llfiil to a positive terminal on the voltage source through wires which are mounted similarly to wire llZS.
The magnetic lield may be provided by any conventional means that is effective for producing a magnetic field across chamber of suflicient strength. ln the illustrated embodiment, a pair of arcuate magnets are contemplated, though only magnet Zd is illustrated in S. By the present invention, a superior mixing of the fuel and air results in chamber lil/l so that a greater thrust is obtained from the ramj'et than is obtainable without the magnetic held and i 'zing potential.
in FEGURE 9, the present invention is shown applied to a turbo-jet engine of generally conventional design, except for the use of ionization electrodes and the magnetic field. Such an engine conventionally comprises an air inlet or nose portion let), downstream of which are fuel orifices ld?. that supply fuel in an atomized condition, which then passes through compressor lid/l into the combustion chamber. Combustion is effected by any conventional means, such as spark plug lido, and in this embodiment the usual turbine 14S and nozzle 15h, which in the drawings are diagrammatically illustrated are downstream of the combustion chamber. Around the combustion chamber are magnets 152 and R54 which provide a magnetic field across the combustion chamber at the region of the electrodes E56, 153, lr6@ and to2, these electrodes being connected to the respective negative and positive terminals of a D.C. source of voltage as indicated in the drawing. The magnetic fields and the electric fields may have the same orientation or, if desired, one or both of the fields at the downstream pair of electrodes may be reversed.
In this embodiment, the ionization and dissociation of the air and fuel molecules take place in the combustion chamber to thus effect a more complete burning of the fuel thereby resulting in a greater output force and higher efficiency than is provided without the use of the ionizing electrical terminals or the magnetic field.
The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
