Description
BACKGROUND OF THE INVENTION
The present invention relates to method and apparatus whereby
combustion processes may be efficiently conducted. In recent years
one of the greatest problems facing the public is the elimination
of air pollution, a great deal of which is due to the exhaust from
various combustion processes. The most troublesome of these seem to
be those wherein a hydrocarbon fuel is combined with oxygen and
burned such as the combustion processes taking place within
gasoline engines, diesel engines, gas turbines, jet engines, boiler
burners and the like. It has been recognized that the pollution
arising from these combustion processes is due largely to
incomplete or inefficient combustion but as yet a practical and
economical method of increasing combustion efficiency has not come
forth. In addition to contributing to pollution, incomplete
combustion is also undesirable in that it increases fuel
consumption and generally reduces mechanical life of the apparatus
in which the combustion takes place due to the formation of
undesirable carbon deposits.
SUMMARY
It is thus an object of the present invention to provide an
economical and relatively simple method and apparatus for
increasing the efficiency of combustion processes. It is also an
object of the present invention to provide a means whereby
pollution of the atmosphere from the exhaust of combustion
processes may be reduced. It is a further object of the present
invention to provide a means whereby an automobile internal
combustion engine may be modified in order to render it more
efficient and release less pollutants than before. Additional
objects will become apparent from the following description of the
present invention.
These and other objects are accomplished by the present invention
which in one of its aspects is an improvement in a combustion
process wherein combustion of a mixture of an oxygen-containing gas
and a fuel is effected in a combustion zone, which improvement
comprises treating said oxygen-containing gas by passing it through
the south pole section of a magnetic field such that the oxygen in
said oxygen-containing gas entering said combustion zone is in the
south pole magnetic state. In another aspect the present invention
is an apparatus wherein combustion of a mixture of fuel and an
oxygen-containing gas is effected in a combustion zone, said
apparatus having oxygen-containing gas intake means, means to
supply fuel and said oxygen-containing gas to said combustion zone,
and magnetic field means to act upon the oxygen in said
oxygen-containing gas to cause the oxygen entering said combustion
zone to be in a south pole magnetic state. The placing of the
oxygen-containing gas in a south pole magnetic state may be
accomplished prior to its being mixed with the fuel. The present
invention is applicable to practically any combustion process, from
that taking place in incinerators to that taking place in jet
engines. It is most applicable and beneficial when applied to
processes using a carbon-based fuel including coal, paper, wood and
the like, but it is most applicable to those utilizing normally
liquid or gaseous hydrocarbon fuels, such as kerosine, gasoline,
natural gas, butane and diesel oil.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the drawings, FIG. 1 illustrates a 4-cycle or 4-stroke
cycle internal combustion engine together with means for a fuel
supply and an exhaust. The engine has an engine cylinder block 10
which includes cylinder 11 in which piston 12 is disposed for
reciprocating movement. The walls of cylinder 11, the crown of
piston 12, and the upper inside face of cylinder block 10, together
define a combustion zone of chamber 13. A spark ignition means,
spark plug 14, in the upper inside face of cylinder block 10
extends into the combustion chamber.
On one side of and included within engine block 10 is an exhaust
passage 15 which has an opening to combustion chamber 13 which
opening is closed by exhaust valve 16. On the opposite side of the
engine is an inlet passage 17 through which a fuel mixture is
supplied to combustion chamber 13 as controlled by inlet valve
18.
Inlet passage 17 is openly connected with an inlet manifold 19
which itself is connected with carburetor 20. Atop the carburetor
20 is an air cleaner assembly having a filter housing 21 and an air
inlet tube 22 extending therefrom. Around the exterior of air inlet
tube 22 is wound a wire coil 23 both ends of which are connected to
a power supply 24 such that current passing through coil 23 sets up
a magnetic field. The coil 23 is wound and the current supplied
thereto in such a manner that the south pole of the magnetic field
is downstream of the inlet tube relative to the north pole, as
indicated by the letters "N" and "S". Although the leads to coil 23
are shown as being connected to its own power supply 24, in the
usual automobile engine this would be accomplished by grounding one
lead and connecting the other to the auto's power supply.
The operation of the embodiment of FIG. 1 is as follows. Air which
contains about 21% by volume of oxygen enters air inlet tube 22 as
shown by the arrow and passes therethrough to filter housing 21. By
virtue of having passed through the magnetic field set up by coil
23, the oxygen in the air entering filter housing 21 will be in a
south pole magnetic state and will remain in that state until
combustion as hereinafter explained. It is emphasized that the
oxygen is in the south pole magnetic state as contrasted with a
north pole magnetic state since the advantages of the present
invention are attained only when the oxygen is caused to be in the
south pole magnetic state. Whether the oxygen in the air is in a
north pole or is in a south pole magnetic state after having passed
through a magnetic field can easily be determined by holding an
ordinary compass near the conduit through which such oxygen is
flowing. If in the desired south pole magnetic state, the needle of
the compass which normally points to the North Pole of the earth
will be deflected toward and point to the conduit containing the
oxygen. In the usual automobile internal combustion engine which
has no wire coil 23 as shown in FIG. 1, the oxygen entering the
filter housing through the inlet tube will not be in a magnetic
state and thus will not cause a deflection of a compass needle
since it is in neither a north pole nor a south pole magnetic
state.
Back to the operation of the embodiment of FIG. 1, the air entering
through filter housing 21 then passes to carburetor 20 wherein it
is combined with atomized and/or vaporized fuel, e.g., gasoline, in
the usual manner. From the carburetor the fuel mixture passes to
the inlet manifold 19 and thence inlet passage 17. The oxygen in
the fuel mixture will still be in the south pole magnetic state and
will remain so until combustion is effected as hereinafter
explained.
At the proper time in the combustion cycle and with the proper
opening and closing of inlet and outlet valves 18 and 16, the fuel
mixture will pass from inlet passage 17 to combustion chamber 13,
be ignited by spark plug 14 and after combustion the exhaust gases
will exit through outlet passage 15.
From the foregoing it may be seen that operation of an internal
combustion engine in accordance with the present invention differs
from the usual only in that the oxygen entering the combustion
chamber is in a south pole magnetic state. However, the combustion
which is accomplished according to the manner of the present
invention will differ from that ordinarily accomplished in that the
efficiency of combustion will be greatly enhanced with greater
conversions of the hydrocarbon fuel to carbon dioxide and the like.
Also, another notable difference is that the exhaust gases leaving
the combustion zone through exit passage 15 will be in a north pole
magnetic state. That is to say the needle on an ordinary compass
will be deflected away from these exhaust gases. The exhaust of the
usual automobile operating without the magnetic field of the
present invention will not noticeably deflect a compass needle at
all. This is also true of an exhaust where the oxygen entering the
combustion zone has been put in a north pole magnetic state (such
as by reversing the positions of the poles in the magnetic field of
FIG. 1) and, as has been pointed out before, putting the oxygen in
a north pole magnetic state does not increase combustion
efficiency.
It is believed that one contributing factor for the present
invention's reduction of pollution is that the exhaust from a
combustion process is in a north pole magnetic state as hereinabove
explained. Accordingly, it may sometimes be convenient to not only
place the oxygen entering the combustion zone in a south pole
magnetic state by use of a magnetic field but also to pass the
exhaust gas from the combustion process through another magnetic
field which will tend to even more cause the exhaust to be in a
north pole magnetic state. The enhancement of the north pole
magnetic state of the exhaust is accomplished in the opposite
manner of causing the oxygen feed to be in the south pole magnetic
state and will not be gone into in detail at this point.
FIG. 1 represents a 4-cycle reciprocating internal combustion
engine, but the present invention is applicable to any internal
combustion engine, either 4-cycle or 2-cycle, and either those
fired by spark ignition means, such as spark plug 14 or those fired
by compression such as the diesel engine. As is well known, the
diesel engine differs from that shown in FIG. 1 mainly in that the
air and the fuel are supplied by separate means to the combustion
chamber and in that ignition is effected by compression instead of
a spark ignition means. That is the air is first supplied to the
combustion chamber and compressed so as to cause the temperature
thereof to rise sharply, and then the fuel is supplied to the hot
compressed air so that combustion is effected. The present
invention is not only applicable to the reciprocating internal
combustion engines, but is also applicable to the types having a
rotary piston, such as the Wankel engine.
The apparatus of FIG. 1 represents only one means of causing the
oxygen to be in the south pole magnetic state. Another way that the
oxygen may be fed to the combustion zone of an ordinary internal
combustion engine is illustrated in FIG. 2. In this figure as well
as in succeeding FIGS. 3 through 6, the engine itself is not
illustrated as operation thereof remains the same regardless of the
manner of causing the oxygen to be in a south pole magnetic state.
FIG. 2 illustrates an embodiment whereby the air cleaner assembly
housing, when manufactured of a ferrous metal, can itself become
the source of the magnetic field. All that is necessary is to
connect point 25 on the outer end of air inlet tube to ground and
connect a point 26 on the filter housing, preferably a point on the
opposite side of the filter housing from the inlet tube, with a
source of current. It is pointed out the above connections are
proper even for cars which have a positive ground system as do many
cars made outside the U.S. Back to FIG. 2, the connection of the
air cleaner assembly as shown will cause the magnetic field to be
set up with the north and south poles thereof in the position
indicated by the letters N and S. Thus as the air passes downwardly
(air flow being indicated by the arrows) to the carburetor, the
oxygen therein will be in a south pole magnetic state.
Another embodiment of the present invention is shown in FIG. 3
which has an air filter 27 connected to carburetor 28 by means of a
ferrous metal tube 29, the air flow being indicated by the arrows.
The tube 29 is connected to air filter 27 and carburetor 28 by
flanges 30 and 31 which by proper insulation material (not shown)
serve to electrically insulate ferrous tube 29 from the air filter
and the carburetor. A point 32 on the upstream end of ferrous metal
tube 29 is connected to ground and a point 33 downstream of the
ground connection is connected to a source of current (not shown).
A magnetic field is thus set up with the north and south poles
thereof in the regions indicated by the letters N and S. In
practically any existing engine where the air supply flows through
a ferrous metal duct (either before or after being filtered) a
magnetic field can be set up therein by the method shown in FIG. 3.
The points of electrical connection to the tube must, however, be
axially removed from each other, that is must be upstream and
downstream from each other, and preferably are on opposite sides of
the duct as is shown in FIG. 3. If the electrical connections are
merely made on opposite sides of the duct but at the same point
along the axis of the tube, the benefits of the present invention
will not be accomplished as a proper magnetic field will not be set
up.
Most internal combustion engines on today's automobiles have an air
cleaner assembly setting atop the carburetor which contains a dry
filter cartridge and one manner of modifying such in accordance
with the present invention is shown in FIGS. 4 and 5. As pointed
out before FIG. 5 is a top view of the air cleaner of FIG. 4 with
the cover of the air cleaner removed. Referring to FIGS. 4 and 5,
an air cleaner assembly having a circular bottom section 34 and a
circular cover 35 is constructed such that a doughnutshaped dry
cartridge-type air filter 36 may be clamped there between. Circular
bottom section 34 contains an opening 37 which fits over and openly
connects the inside of the air cleaner assembly with the usual
carburetor (not shown) such that outside air passes through the
filter 36 and then downwardly to the carburetor through opening 37
as indicated by the arrows. Also contained within the air cleaner
assembly is a funnel-shaped or cone-shaped coil 38 which increases
in diameter from the top to the bottom thereof. As may be seen the
bottom of the coil is of a diameter substantially that of the
inside of filter 36 such that this bottom coil is as far removed
from opening 37 as possible. Contained on coil 38 are rubber
washers 39 which prevent contact of the coil with and electrically
insulate it from the other parts of the filter assembly although
this may also be accomplished by coating the coil with an
insulating material. In operation of this device upper end 40 and
lower end 41 of the coil will be connected to a power supply so as
to cause a magnetic field to be set up due to current passing down
the coil. The direction of the coil winding and the direction of
the current flow therethrough will be such that the south pole of
the magnetic field is at upper end 40 and the north pole is near
the lower end 41. In the usual U.S. manufactured automobile having
a 12 volt negative ground system, this is accomplished by having
the coil clockwise wound with lower end 41 thereof being connected
to ground and the upper end 40 thereof being connected to the
automobile's power supply, these connections not being shown. At
first glance it appears that such an arrangement would not impart
south pole magnetic state to the oxygen in the air going downwardly
through opening 37 but it has been found that such is accomplished
since the arrangement tends to place the south pole of the magnetic
field near the center of the air cleaner assembly and the north
pole near the periphery thereof. Although the coil in FIGS. 4 and 5
is placed within the air filter 36, it could also be placed outside
thereof or acutally embedded therein.
FIG. 6 represents another particular embodiment whereby the air
cleaner assembly of an internal combustion engine is modified to
cause the oxygen passing therethrough to be in a south pole
magnetic state. Referring to FIG. 6, an air cleaner assembly which
normally is mounted above a carburetor, contains a ferrous metal
air inlet tube 42 and an air filter housing 43 which are connected
to and electrically insulated from each other by flange 44. A point
on the outer end of inlet tube 42 is connected to ground as shown
and a point 45 downstream of and on the opposite side of the tube
therefrom is connected to a power supply (not shown). The oxygen in
the air entering inlet tube 42 is thus caused to be in the south
pole magnetic state upon passing to the carburetor and thence to
the combustion zone in the same manner as that embodiment shown in
FIG. 3.
All of the foregoing embodiments have involved causing the oxygen
in the air to be put in a south pole magnetic state prior to being
mixed with the fuel. This is preferred--and the easiest manner to
convert an existing engine--but it is pointed out that the oxygen
fed to the combustion zone may be put in a south pole magnetic
state after being mixed with the fuel. All that is required is that
the oxygen be in the south pole magnetic state at the time of
combustion. For example, a device may be placed between the
carburetor and intake manifold which causes the oxygen in the fuel
mixture to be converted to the south pole magnetic state. FIG. 7
illustrates the general configuration of a device that may be
utilized between a carburetor and the intake manifold so as to
cause the oxygen to be in a south pole magnetic state. Of course,
it could also be utilized at other points. Referring to FIG. 7, it
has been found that a piece of ferrous metal shaped as shown, that
is, with a discontinuous or unclosed loop 46 having one end thereof
projecting outwardly therefrom in a projection 47, if connected
properly to a power supply will set up a magnetic field the south
pole of which is within the loop and the north pole of which is
outside the loop near the projection 47. This is accomplished in a
12 volt negative ground system by connecting the outer end of the
projection 47 to ground and connecting the end of the loop 48 not
projecting outwardly to a power supply. The cross-sectional area of
the ferrous metal utilized will depend on its desired placement and
could, for example, be circular (such as when made of an iron rod)
or rectangular (such as when made from a flat iron bar). At any
rate, such a device as shown in FIG. 7 may be placed such that the
loop surrounds the conduit through which the oxygen passes so as to
cause the oxygen to be in a south pole magnetic state. It will
usually be most convenient to mount or embed the loop in a plate or
collar which may be inserted at the desired position--such as
between a carburetor and an inlet manifold.
The device shown in FIG. 7 does not have to be formed from bar
stock but for some applications may even be formed from thin sheet
metal such as the device shown in FIG. 8. Such a device is
particularly useful for actually clamping around a long pipe or
conduit having an oxygen-containing gas flowing therethrough. As
may be seen, FIG. 8 like FIG. 7 has a discontinuous loop 46, one
end of which projects outwardly therefrom in projection 47. The
outer end of projection 47 is grounded and a point 48 at or near
the non-projecting end of the loop is connected to a power supply
(not shown). Of course, the device of FIG. 8 could be embedded
within a collar for easy mounting and could be manufactured in two
or more pieces which when clamped together would give the desired
shape and effect.
In the devices of FIGS. 7 and 8, the reversal of the direction of
current flow therethrough will cause the north pole to be within
the loop and the south pole outside thereof. With the north pole
within the loop these devices become useful for application to the
exhaust from a combustion process as mentioned above.
The foregoing described embodiments have all utilized
electromagnets but permanent magnets may also be utilized, and are
preferred, in the present invention. In fact, in a combustion
apparatus which does not have a power supply connected thereto or
have a generator in connection therewith, permanent magnets such as
bar magnets may be utilized. Thus, an ordinary 2-cycle gasoline
engine such as found on a lawnmower or outboard motor engine may be
modified in accordance with the present invention by use of
permanent magnets. All that is involved is mounting one or more bar
magnets such that the south pole end extends into or near the air
intake while the north pole of the bar magnet is as far removed
from the air inlet as possible. In other words the south pole
section of the permanent magnet should be nearest the
oxygen-containing gas passing through the air inlet and the north
pole section should be as far away as possible, such as where the
north pole section extends radially outward. For example, FIG. 9
illustrates a collar 49 having bar magnets 50 embedded therein and
projecting radially from opening 51. As may be seen the south pole
of the bar magnets extends up to and is in close proximity with
opening 51 while the north pole of the bar magnets is removed from
opening 51. Air flowing through opening 51 would thus assume a
south pole magnetic state. If the magnets were reversed, air
flowing through opening 51 would assume a north pole magnetic
state. Although only two magnets are shown in FIG. 9, there could
be only one magnet present or there could be more than two
present.
In operating according to the present invention it has been found
that the most efficient combustion is effected when the magnetic
field utilized to treat the oxygen has a magnetic field strength of
about 5,000 to 10,000 Gauss although it can vary over an extremely
wide range, for example, from 1,000 to 20,000 Gauss and higher. In
an ordinary automobile engine with the type device shown in FIGS. 4
and 5, this will require only about 1 to 5 amps which is less than
many car radios draw. It is emphasized that the range of 5,000 to
10,000 Gauss is the magnetic field strength desired when the oxygen
does not become de-Gaussed before entering the combustion zone. In
many apparatuses, depending, of course, on the treatment received
by the oxygen after being put in the south pole magnetic state, the
magnetic field strength must be at a higher Gauss level since it
may be de-Gaussed to some extent before reaching the combustion
chamber. In the usual automobile gasoline engine de-Guassification
usually does not occur even when the oxygen is treated in the air
filter section of the engine as illustrated in FIGS. 1 through 6.
However, if the oxygen is put in a south pole magnetic state in the
air filter section of a diesel engine it has been found that the
oxygen will be de-Gaussed to some extent in the blower section and
thus the magnetic field strength should be about 13,000 Gauss in
air filter section in order to have the oxygen at the proper level
when it reaches the combustion chamber.
The strength of the magnetic field of a permanent magnet is
constant under most conditions but the field strength may be
controlled in an electromagnet such as those in FIGS. 1 through 8
by varying the amount of current flow. The control of the current
flow is usually accomplished, for example, by placing a
potentiometer in the circuit, preferably in the lead which goes
from the electromagnet to ground. For example, in FIG. 2, the
potentiometer is most conveniently placed between point 25 and
ground.
The foregoing discussion has been limited to reciprocating internal
combustion engines such as the 4-cycle and the 2-cycle engines
found in most of today's automobiles since that is where the
present invention is presently most advantageous. However, the
present invention is by no means limited to such internal
combustion engines and can certainly be utilized to great advantage
in any combustion process wherein a hydrocarbon fuel and oxygen are
combined and combustion of this mixture effected. For example, the
present invention is very useful in rockets, gas turbine or other
jet engines and serves to increase the combustion efficiency of
such engines. "Jet engine" as used herein is used in a generic
sense to include any engine whereby expanding hot gases from a
combustion zone are used as reaction forces--whether to actually
produce a forward thrust by exiting through a narrow opening and/or
by turning a turbine which in turn mechanically drives other parts.
Referring to FIG. 10, there is illustrated a typical gas turbine or
turbojet engine having a compressor section 52, combustion chamber
53, and turbine section 54. In the ordinary operation of this
engine air enters the front, passes through the compressor section
52 where it is compressed and then goes into combustion chamber 53
where, after mixing with fuel such as kerosine fed through fuel
line 55, combustion takes place. The hot expanding gases then exit
through and drive the turbine 54 and in some cases also pass
through an afterburner (not shown). When modified according to the
present invention the air entering the combustion zone would first
be passed through one or more magnetic fields in order that the
oxygen therein would be in a south pole magnetic state. This can be
accomplished for example by setting up a proper magnetic field at
the entrance of the engine through the use of coil 56 and also by
the use of coil 57 at the entrance to the combustion chamber. These
coils must, of course, be connected to a source of current which is
not illustrated. When a magnetic field is set up at the entrance of
the turbojet engine such as by coil 56, it is pointed out that the
substantial de-Gaussification of the oxygen occurs as it passes
through the compressor section and thus the strength of the
magnetic field must be adjusted accordingly. If an after burner is
present in the jet engine the oxygen entering the combustion zone
thereof can also be placed in a south pole magnetic state in
accordance with the present invention so as to achieve more
efficient after-burning. Jet engines, including ram jets, pulse
jets, rockets, turbojets and other gas turbines, modified in
accordance with the present invention have increased combustion
efficiency and thus contribute less to pollution of the atmosphere
than do the usual jet engines. Fuel consumption of the jet engines
will also be enhanced.
The present invention may be applied to combustion processes other
than the combustion process taking place within an engine, for
example, to the ordinary burners found in heaters and boilers and
to the combustion which takes place in the regeneration section of
a fluid catalytic cracking process. In this latter-type process a
feed such as gas oil is contacted in a reactor section with a
fluidized bed of hot, finely-divided catalyst causing the feed to
be cracked to the desired components such as gasoline. A small
portion of the hot catalyst used in the reactor section (usually a
finely-divided clay) as a source of heat is continuously withdrawn
and passed to a regenerator section in order that the catalyst may
be regenerated. After regeneration the catalyst is cycled back to
the reaction zone. Regeneration is needed not only to reheat the
catalyst but also to burn off carbonaceous deposits which are
formed on the catalyst in the cracking process of the reaction
section. These carbonaceous deposits generally consist of elemental
carbon plus various hydrocarbon tars. The regeneration of the
catalyst is the combustion process which the present invention
enhances, the combustion taking place when the preheated air fed to
the regeneration section is first treated such that the oxygen
therein is a south pole magnetic state then more efficient
regeneration is accomplished and also equipment fouling is
reduced.
FIG. 11 illustrates a burner 58 constructed in accordance with the
present invention. The burner 58 consists of a cylindrical housing
59 having a closed end 60 and an open end 61. A feed line 62
extends through closed end 60 so as to feed a fuel gas such as
natural gas. Air enters burner 58 through openings 63 in the
cylindrical housing and then most of the air along with the fule
gas passes through a Venturi 64 where the two are thoroughly mixed.
Venturi 64 is constructed of a ferrous metal and is concentrically
suspended within cylindrical housing by spider 65 and is also
electrically insulated therefrom although such insulation is not
illustrated. Some of the air entering openings 63 does not pass
through the Venturi but instead passes through the concentric space
between the housing and the Venturi. Upon exiting the Venturi
thoroughly mixed, burning or combustion of the fuel gas-air mixture
occurs in the combustion zone at or near open end 61 as indicated
by flame front 66. In accordance with the present invention a point
on the downstream end and also a point on the upstream end of the
Venturi 64 is connected to a power supply 67 in a manner similar to
the devices of FIGS. 3 and 6 such that a magnetic field is set up
by the current passing through Venturi 64. The current flow is such
that the north pole of the magnetic field is near the upstream end
of Venturi 64 (as indicated by the letter N). Since the air and
fuel gas mixture passes through the south pole section of the
magnetic field after it passes through the north pole section, the
oxygen exiting the Venturi will be in a south pole magnetic state
and will remain so until the time of combustion.
By the term "oxygen-containing gas" as used herein is meant any gas
which contains the necessary oxygen to support combustion. Such may
be pure oxygen, air, oxygen-enriched air or any other mixture of
oxygen with other gases. For economical reasons air is the usual
source of oxygen for a combustion process.
It is recognized that various prior art processes have disclosed
the use of magnetic fields in combustion processes. For example,
U.S. Pat. No. 3,349,354 to Miyota, U.S. Pat. No. 3,110,294 to
Nyman, U.S. Pat. No. 3,266,783 to Knight and British Patent
Specification No. 714,015 to Sabetay all disclose the use of
magnetic fields in combustion processes. However, the present
invention is simpler in operation than the methods and apparatus
disclosed in such reference in that the present invention may be
used to treat the oxygen-containing gas alone before being mixed
with the fuel while the foregoing references deal only with
treating the fuel-air mixture. Further the foregoing references all
call for the use of an applied electrical potential, that is the
fuel-air mixture is subjected to the influence of an electric
field, sometimes also referred to as an electrostatic field. The
present invention does not require and may be operated without the
treatment of either the oxygen-containing gas or the fuel prior to
combustion by use of an electric or electrostatic field. Thus an
apparatus of the present invention may be much more simple in
nature than those of the prior art since no means is needed for
subjecting the oxygen-containing gas or fuel to an electric or
electrostatic field prior to combustion.
EXAMPLE
The exhaust from an eight cylinder, 4-cycle gasoline automobile
engine was analyzed for the presence of various combustion products
and then the same automobile engine was modified according to the
present invention by use of an apparatus as shown in FIG. 4 and the
exhaust once again analyzed. In the modified engine the current
carried through the coil was about 3 amps causing the oxygen
entering the combustion chambers to be in the south pole magnetic
state. The field strength of the magnetic field was about 10,000
Gauss. Both tests were conducted with the engine at 600 RPM. The
results of the exhaust analysis are shown in the following
table.
______________________________________ Component Mole Percent

As may be seen from the foregoing greater combustion efficiency was
attained when the engine was modified in accordance with the
present invention as evidenced by the fact that a greater amount of
oxygen was consumed and more carbon dioxide was produced with the
modified engine.
