THE GENERAL BACKGROUND OF THE INVENTION
Today, people are becoming more cognizant of the needs
to conserve gasoline. The gasoline is increasing in price and
people are interested in securing more miles per gallon of gaso-
line. In fact, in many instances, it is necessary that better
mileage be realized from gasoline in order for people to continue
driving their automobiles.
One of the components in processing fuel for burning
in an internal combustion engine is the carburetion system. With
an improvement in the carburetion system and the vaporization of
the fuel, it is possible to realize better gasoline mileage or
more miles per gallon of gasoline from a given volume of fuel.
With this in mind, I have designed and made units to be used
with the carburetion system to increase the vaporization of the
fuel and to form a more homogenous air-fuel mixture vapor to
realize more miles from a given volume of gasoline.
With this invention, installed on my own automobile
for experimental purposes, I have increased the mileage from a
given volume of gasoline.
THE GENERAL DESCRIPTION OF THE INVENTION
According to the invention, there is a means for
heating the fuel prior to introducing the fuel into the carburetor.
This means is referred to as a fuel expander. The temperature of
the fuel is adjusted to a predetermined desirable temperature.
The fuel expander makes it possible to heat the fuel, when
necessary, to the desired predetermined temperature. Further,
the fuel expander makes it possible, when necessary, to cool the
fuel to the desired predetermined temperature. With the fuel
expander, it is possible to control the temperature of the fuel
to the desired predetermined temperature.

In a broad aspect the invention resides in a fuel
expander comprising a housing for housing a liguid; a cold water
inlet connecting with said housing; a hot water inlet connecting
with said housing; a heat sensitive means inside said housing;
a valve means functioning with said cold water inlet, and with
said hot water inlet for controlling the flow of cold water and
for controlling the flow of hot water into said housing to achieve
a heating water of a desired temperature and also connecting with
said heat sensitive means; a fuel line positioned in said hous-
ing for flowing fuel through said housing and to heat said fuel
to a temperature approximately that of said heating water of a
desired temperature; and said heat sensitive means in reacting to
the temperature in the housing moving said valve means to regu-
late the flow of hot water through said hot water inlet and to
regulate the flow of cold water through said cold water inlet.
Another facet of the fuel expander is that the fuel in
the carburetor can be circulated through the fuel expander so as
to maintain the fuel in the carburetor at the desired predeter-
mined temperature.
In a further embodiment of the invention there is
provided a humidifier for humidifying the air prior to the air
passing to the carburetor. It is possible to increase the
moisture content or the relative humidity of the air prior to
flowing to the carburetor. Generally, moisture in the air-fuel
mixture vapor which is introduced into and burned in the internal
combustion engine provides a more uniform burning of the fuel
and a more desLrable burning of the fuel. This, in itself, re-
sults in an increase in the gas mileage realized from a given
volume of fuel.
In a still further embodiment, there is provided an
air-fuel mixture varpoizer which is positioned between the
~ _3_
''~ 1!3
~070580
carburetor and the internal combustion engine. The air-fuel mix-
ture vaporizer heats and mixes, by turbulence, the air-fuel
mixture vapor from the carburetor. This results in a more uni-
form mixture of fuel and air for introduction into the internal
combustion engine to realize a more uniform burning of the fuel
and to realiæe a more complete burning of the fuel in the
internal combustion engine, and, as a consequence, better
mileage from a given volume of gasoline for a motor vehicle
using an internal combustion engine.

1 The fuel expander may be used by itself or may be used
2 in conjunction wlth either the humidifier or the vaporizer or may
3 be used in conjunction with the humidifier and the vaporizer.
4 Further, the humidifier may be used by itself or in conjunction
with the vaporizer. And, finally, the vaporizer may be used by
itself.
8 THE OBJECTS AND THE ADVANTAGES

THE DETAILED DESCRIPTION OF THE IN~ENTION
2 -_
3 In FIG. 1, there is schematically illustrated the inter-
4 nal combustion engine 10, the fuel expander 12, the air-fuel mix-
tuer vaporizer 14, and the humidifier 16 as used and associated
3 together for decreasing the consumption ~f fuel without any sub-
7 stantial change in the performsnce of the internal combustion
8 engine 10.
In FIG. 1, it is seen that there is a radiator 18. The
11 radiator 18 has a cold water outlet 20 which branches into a line
12 22 which connects with the water jacket of the internal combustion
13 engine 10. The internal combustion engine 19 has a hot water exit
14 line 24 which connects with the air-fuel vaporizer. 14 to supply
heat energy to the vaporizer 14. The air-fuel vaporizer 14 has
16 an exit line 26 which returns to the radiator 18 so that the hot
17 water from the internal combustion engine 10 can be cooled for re-
lB cycling purposes.
19
ao The cold water line 20 from the car radiator 18 also
al branches into a line 28 which connects with the heater 30.
aa
23 The line 28 branches int~ a line 32 which connects with
24 the fuel expander 12.
26 The hot water line 26 branches into a hot water line 34.
27 The hot water line 34 in turn branches into a line 36 and into a
28 line 38, The line 36 connects with the heater 30. Further, the
29 line 36 branches into a line 4~ which feeds into the valve control
means 42 associated with the fuel expander 12.

1~7V580
1 The line 38 from the hot water line 34 leads into an auxil-
2 iary radiator 44. The auxiliary radiator has an exit cold water
3 line 46 which feeds into the valve control means 42. Naturally,
4 the purpose of the auxiliary radiator 44 is to cool the hot water
from the wster jacket of the internal combustlon engine 10.
B
7 The line 32 from the fuel expander 12 and the line 28 are,
8 essentially, cold water return lines for introducin~ the cold water
~ into the water jacket for the internal combustion engine.
Il The lines 36 and 40 are feeder lines for the heater 30
12 and the valve control means 42 and the fuel expander 12.
13
14 Also, the cold water line 46 is a feeder line for the
valve control ~eans 42 and the fuel expander 12.
16
17 There i6 a fuel tank 50 which has an exit line or fuel
18 line 52. In the fuel line 52 is a fuel pump 54. The fuel pump 54
19 connects with the line 58 which runs into the fuel expander 12 and
ao out of the fuel expander 12 and connects with the carburetor 60.
21
22 Another l~ne 62 connects with the bottom of the bowl of
23 the carburetor and runs into the fuel expander 12 and then runs
24 out of the fuel expander 12 an~ connects with the top of the b~wl
of the carburetor 60. At times, it may be desirable to use the
26 line 62 to maintain the temperature of the fuel in the carburetor
27 at the desired predetermined temperature.

29 A humidifier 16 connects with and leads into the carbu-
retor 60 by means of a line 64

10~0580
I The air-fuel mixture v~porizer 14 connects with the car-
2 buretor 60 by means of a line 66 and leads into the internal com-
3 bustion engine 10 by means ~f a line 68.
There is an exhaust line 70 leading fro~ the internal
B combustion engine 10 to the exhaust system for the internal com-
7 bustion engine 10,
9 With reference to FIG. 2 and ~he fuel expander 12 and
associated valve 42, it is seen that the fuel expander 12 comprises
Il a tubular or right circular cylindrical housing 80 which is tapped
12 on its right end at 82 so as to receive the heater end plate 84
13 which is externally threaded at 86. The end plate 84 is screwed
14 onto the housing 80.
16 At the left end of the housing B0, there is a valve end
17 plate 88 which is threaded at 90. The housing 80 is internally
18 tapped at 92 so as to receive the valve end plate 88.
1~
ao In the valve end plate 88, there is a tapped central open-
21 ing 94 for receiving the housing 96 of the mixing valve 42. The
a2 housing 96 has an externally threaded nipple 98 for screwing into
23 the tapped central opening 94. Also, the housing 96 has a central
24 paSsageway 100.
a~ In the wall of the housing 96 is a hot water tapped
27 passageway 102 and in the housing 96 is a cold water tapped passage-
28 way 104.
29
At the nipple end of the central passageway 100, there
31 is a tapped passageway 106 ~or receiving a tubular support housing
32 108 which is externally threaded at 110.
10705~0
1 The outer end of the support housing 108 is externally
2 threaded at 112 and receives an end plate 114 which is internally
3 tapped at 116.
S In the end plate 114, there is a tapped.central opening
6 118.
8 There is screwed into the tapped central opening 118, a
~ thermostat cartridge 120 have external threads 122 on one end.
The thermostat cartridge 12- has a rod 122 which projects, in FIG.
11 2, left from the cartridge 120. The rod 122 has an external
la threaded end 124 which is screwed into a valve head 126. The
13 externally threaded rod 124 is screwed into central tapped passage-
i4 way 128 in the valve head 126.
16 Between the end of the valve head 126 and the end of the
17 housing 96, there is positioned a spr~ng 130, The cpring 130 urges
18 the valve head 126 toward the thermostat cartridge 120.
1~
In the support housing 108 there are openings 132 to
al allow hot water and cold water to flow from the central passageway
aa lOO and through the support housing 108 and through the passageways
23 132 into the housing 80.
24
In the valve head 126 are a number of longitudinal
26 passageways 134 connecting the spring end of the central passage-
27 way 100 with the nipple end of the central passageway 100 so that
28 hot water can flow through the hot water tapped passageway 102,
a9 into the spring end of the central passageway 100, through the
longitudinal passageways 134 in the valve head 126, and into the
31 support hous ing 108 and through the opening 132 and into the
32 housing ~0.
1070580
1 In FIGS. 1, 2, and 3, lt is seen that there are lines 58
2 and 62 in the housin~ 80. More particularly, the lines 62 connect
3 with the lower part of the bowl of the carburetor 60 and also with
4 the upper part of the bowl of the carburetor 60 so as to flow fuel
from the carburetor 60 through the housing 8~ and.back to the car-
6 buretor 60. Also, the line 52 connects with the fuel tank 50 and
7 the fuel pump 54. The fuel pu~p 54 connects with the fuel line S8
8 which enters the housing 80 through the heater end plate 84. As
9 previously stated, the line 58 leRves the housing 80, or the fuel
expander 12, and connects with the carburetor 60 to introduce fuel
11 into the carburetor 60.
12
13 For ease of illustration, the entrance of a fuel line 58
i4 into the housing 80 will be identified by reference numeral 140 and
the exit of the fuel line 58 from the housing 80 will be identified
16 by reference number 142. Also, for ease of ~llustration, the en-
17 trance of the line 62 into the housing 80 will be ident~fied by
18 reference numeral 144 and the exit of the line 62 fro~ the housing
19 80 will ~e identified by reference numeral 146.
21 In FIG 2, it is seen that in the heater end 84 that there
a2 iS a tapped passageway 148 in the lower part of the end plate 84.
23 In this tapped passageway 148, there is positioned a bushing 150
24 which positions an auxiliary electric heater 152.
2~
a6 In the heater end plate 84, near the upper part, there is
27 a tapped passa~eway 156. There is screwed into the tapped passa~e-
28 way 156 a threaded pipe 32 which returns water from the ~uel expander
29 12 to cold water line 28, see FIG. 1.
3~
31 In operation, the fuel expander 12 and the valve 42 func-
32 tion to maintain the liquid in the fuel expander 12 at a desired
107058~t
1 temperature so as to maintain the gasoline in the carburetor at
2 said desired temperature. The desired temperature is in the range
3 of about 130F to,approximately, 140F.
The thermostat cartridge 120 is designed to operate in
6 the range of about 125F to, approximately, 135F.
8 Assume that the internal combustion engine has not been
9 operated for a number of hours so that the internal combustion
engine is cold. This means that the water in the auxiliary radia-
11 tor 44 and also in the car radiator 18 is cold and tha~ the water
12 in the fuel expander 12 is cold. The thermostat cartridge 120 is
13 retracted so that the valve head 126 covers the cold water passage-
i4 way 104 and prevents water entering into the central passageway
100 and into the housing 80. Also, the valve head 126 is away from
1~ the hot water pas5ageway 102 so that hot water can flow freely into
17 the central passageway 100 and into the housing 80, Upon, initially,
18 startin~ the internal c~mbustion engine, it may be desirable to
1~ use the auxiliary electric heater 152 to heat the liquid in the
housing 80. Further, with the heating of the water in the radia-
21 tors 18 and 44, a warmer water will enter through hot wat2r passage-
22 way 102 and into the central passageway 100 and flow into the
a3 housing 80. The temperature of the liquid in the housing 80 in-
24 creases and the thermostatic cartridge 120 expands so as to move
the valve head 126 toward the end of the central passageway 100
a6 and to compress the spring 130. When the temperature of the
27 liquid in the housing 80 reaches, approximately, 135F, the thermo-
23 stat cartridge 120 has expanded sufficiently to move the valve
29 head 126 over the hot water passageway 102 so as to prevent hot water
flowing into the central passageway 100. To repeat, this occurs
31 when the t~perature of the liquid in the housing 80 is about 1350F,
32 viz., in the desired temperature range of about 130F to, approxi-
-12-
10>7~580
1 mately, 140~F. The fuel 156 flowing in the fuel line 58 is heated
2 to, appro~imately, 135F. If there is the line 62 connecting with
3 the car~uretor 60 and the fuel expander 12, the fuel in the line
4 62 is heated to, approximately, 135F. Cold water port is closed
at all times except when the temperature exceeds the desired tem-
perat~re and cold water is needed to cool the fuel to a temperature
7 in the desired range.
8 If the temperature of the liquid in the housing 80 falls
9 below about 130F, the cold water passageway 104 is covered by the
valve head 126 so as to prevent the flow of cold water into the
11 passageway 100 and the hot water passageway 102 is opened so that
12 not water can fl~w into the central passageway 100 and into the
13 housing 80. In this manne~ the temperatu~e of the water in the
14 housing 80 can ~e increased to a temperature in the range of about
~ 130F to, approximately, 140F.
i6 If the temperature of the water in the housing 80 is
17 greater than about 140F, the thermostat cartridge 120 expands so
18 as to move the valve head 126 over the hot water passageway 102 to
19 prevent the flow of hot water into the central passageway 100 and
ao also the valve head 126 does not cover the cold water passageway
21 104 so as to allow cold water to flow into the central passageway
a2 lOO to allow cold water to flow through the passageway 104 and into
23 the housing 80 so as to cool the water in the housing 80 to be in
24 a range of about 130 F to, approxim~tely, 140F
An auxiliary electric heater brings the expander to 100F
26 then shuts off when the hot incoming water reaches that temperature
27 or a greater temperature.
28 Naturally, after the water in the housing 80 h~s reached
29 the temperature in the range of about 130F to, approximately, 140F,
there is no need for the auxiliary electric heater 152. The aux~-
31 liary electric heater 152 can connect with a source of electricity,
32 such as a battery, ~y means of wires 160 and 162.
-13-
~?70580
1 When the expander reaches its desired temperature, both
2 parts are closed, placing the mixing valve in a parked position.
3 Then the valve can move to allow the flow of cold water or hot
4 water as required.
From the foregoing, it is seen that the.fuel expander 12,
in conjunction with the valve control means 42, controls the tem-
7 perature of the fuel 56, when the internal combustion engine 10 is
8 fully operational and up to the desired temperature, so as to
9 introduce fuel at a predetermined temperature in the range of
about 130F to, approximately, 140F into the carburetor 60.
11 I have constructed a fuel expander 12 and have placed
12 it on my automobile, a 1972 El Camino, with the 307 cu. in. V-8
13 engine and automatic engine. The mileage on the automobile was
li about 24,000 miles. It is to be realized by the reader that the
fuel expander 12 and valve control means 42 I made and used on
16 my automobile was made and used by itself. There was not used the
17 humidifier 16 and there was not used the air-fuel mixture vapori-
18 zer 1~. There was used only the fuel expander 12 and valve control
1~ means 42.
In Table No. 1, Relative Mileage, there is indicated the
21 mileage on said automobile for a speed of 50 miles an hour and
22 with no heat to the fuel expander 12 or a heat of about 60F. The
23 mileage was 15.2 miles per gallon. With the te~'>erature of the
24 fuel expander 12 at 100F, the mileage increased to 17.2 miles per
gallon. With the temperature of the fuel expander 12 at 130F,
26 the mileage increased to 1~.~ miles per gallon. From this data
27 for 50 mph, it is seen that by operating the fuel expander at
28 130 F, there is an increased mileage of approximately 23% as com-
29 pared with the fuel expander being at a temperature of 60F.
A test was run on said engine at 30 mph and no heat in
31 the fuel expander or a temperature of about 60F. The mileage was
32 1~.5 miles per gallon. With the fuel expander at a temperature
-14-
- 1~7~580
1 of 130F, the mileage increased to 28 miles per gallon, or a per-
2 centage increase of about 41%.

11From these figures, it is seen that by heatlng the gaso-
12 line or fuel 56 to a temperature of about 130F, there is an in-
13 crease in the mileage received from a given volume of fuel. To
14 repeat, one of the advantages of this fuel expander 12 is to main-
tain the temperature of the fuel 56 in a desired range of about
16 130F to, approximately, 140F. The fuel expander 12 has the cap-
17 ability of heating fuel 56 at a temperature less than 130F and
18 also has the im~ortant capability of cooling fuel at a temperature
1~ greater than about 140F The result is a fuel maintained in the
desired temperature range of about 130F to about 140F. The tem-
21 perature i8 held to within 3F of the desired temperature. For
22 example, the 140F sensor operates between 138F and 141F.
23In FIGS 4 and 5, there is illustrated ~ humidifier 16
24 having a housing 170 with a top member 172 and bottom member 174,
a5 a side wall 176 connecting ~he 0embers 172 and 174 and another
26 side wall 178 connecting the members 172 and 174.
27In FIG. 5, it is seen that there i* a left end wall 1~0
28 having an opening 1~2. A housing 184 connects with the opening
29 182 and the housing 1~4 leads to the carburetor 60.

10705~0
I In FIG. 4, it is seen that in the right wall there is an
2 opening 186 which connects with an inlet housing 188. The inlet
3 housing 188 connects with an air filter 190 which in turn connects
4 with an air inlet 192.
6 In the housing 170, there is a support plate 194, posi-
7 tioned below the outlet 182. There is supported on the support
8 plate 194 a plurality of alternating baffles 196 and 198. In FI~.
~ 5, it is seen that these baffles 196 and 198 alternate with each
other so as to cause turbulence in the air flowing through the
11 humidifier 16.
12
13 A pipe 200 connects with the lower part of the housing
li 170. The pipe 200 also connects with the pump 202 which in turn
connects with the pipe 204 and which pipe 204 re-enters the hous-
16 ing 170, above the baffles 196 and 19~, and drips water from open-
17 in~s 206 in between the baffles 196 and 198 so as to add moisture
18 to the incoming air. The addition of moisture t~ the incoming air
19 has the beneficial effect of the gasoline burning more evenly
ao instead of tendin~ to explode unevenly in the internal combustion
21 en~ine.
2a
a3 Further, there may be a circulation fan 20~ in the
24 entrance into the unit 170 so as to force air a~ainst the baffles
196 and l9~. A fan is used to drive the pump, to pump water up
26 onto the baffles.
27 In the h~usin~ 170, it is seen that there is a reservoir
28 of water 21U which lies at the bott~m of the housing so that the
29 pump 202 can pump the water into the upper part of the housing
and over the baff les 1~6 and 19~ and also to allow the water to
31 drip in between the baffles 196 and l9~.

1 In this manner, the air enterin~ into the humidifier 162 passin~, throuy,h the humidifier 16 can pick up moisture so as to
3 raise the relative humidity.
6 The air-fuel mixture vaporizer is illustrated in FIGS.
~ 6, 7, and 8. The vaporizer 14 comprises a top plate 220 and a
7 bottom plate 222. There is a side wall 224 connecting the plates
8 220 and 222 and also there is a side wall 226 connecting the plates
~ 220 and 222.
11 There is spaced inwardly and apart from the wall 224, a
12 wall 228 which has a central openin~, 230. Also, there is spaced
13 inwardly from the wall 226 a wall 232 and which wall has a central
14 openin~, 234.
16 A central deflection tube 236 connects with the wall 228
17 and also connects with the wall 232.
18
1~ In FIG. 8, it is seen that the deflecti~n tube 236 is in
the confi~,uration of an inverted T wherein there i8 a cross member
21 238 and a ley, 240.
22
23 In the upper plate 220,there are ~wo spaced apart holes
24 ~r passaC~eways 242. In the l~wer plate 222, there are two spaced
apart holes or passageways 244.
26
27 In FIG. 8, it is seen that there are outside walls 246
28 and 248. Spaced inwardly of the wall 246 is a wall 250. Spaced
29 inwardly of the wall 248 is a wall 252.
31 In FIG. 6, it is seen that there is a baffle 256 which
32 extends between the corner of the inner walls 232 and 252 and the

3 Also, it is seen, in FIG. 6, that there is a baffle 258
4 which extends between the corner of the inner walls 228 and 250
and the corner of the outer waLls 224 and 246.
7 There is a water inlet pipe 260 which projects through
8 an opening in the walls 248 so as to allow water to enter the vapor-
~ izer 14. Further, there is a water outlet pipe 260 which projects
through a passageway in the wall 246 so as to allow water to leave
11 the vaporizer 14.
12
13 In practice, water enters the water inlet pipe 260 and
14 flows between the walls 24~ and 252 and then flows between the walls
228 and 224 so as to enter the center deflection tube 236, The
16 center def~ection tube 236 is positloned below the inlet opening
17 242 and positioned above the outlet opening 244. The water flows
18 through the center deflection tube 246 and between the wall 232
19 and the wall 226 and then flows between the wall 246 and the inner
wall 250. Then, the water flows out of the water outlet tube 260.
21 Naturally, warm water from the water jacket of the internal com-
22 vustion en~ine 10 flows through the hot water line 24 and to the
23 hot water inlet Line 260. The water flows from the vaporizer 14
24 and thro~h the water outlet tube 260 to the line 26 which leads
to the car radiator 18.
26
27 In the baffle 256, there is a hole or passageway 260.
23 In the baffle 25~,there is a hole or passageway 262. The holes
29 260 and 262 allow some circulation of hot water in the vaporizer
14 other than throu~h the center deflection tube 236.

1 In effect, the air-fuel mixture flows from the carbure-
a tor 60 and into the air-fuel mixture vaporizer 14. The center
3 deflection tube 236 is hot, approximately, the temperature of the
4 water leavin~ the water jacket of the internal combustion engine.
The air-fuel mixture from the carburetor 14 comes.in contact with
6 the hot center deflection tuber, at a temperature in the range of
7 about 170F to, approximately, 180F, and if there are drops of
8 fuel in this air-fuel mixture, the hot center deflection tube 236
~ vaporizes these drops of fuel so as to have a vapor of fuel and
air. Further, the shape of the center deflection tube 236 is such
11 aR to lend turbulence to the air-fuel mi~ture from the carburetor
12 60 and such tur~ulence assists in vaporizing the drops of fuel.
13
i4 I consider that the air-fuel mixture vaporizer 14 assist
in forming a homoOonous air-fuel mixture and is of value in the
16 formation of this homogonous air-fuel mixture.
17
18 From the foregoin~, it iB seen that I have provided a
19 combination of individual components, such as a fuel expander 12,
the air-fuel mixture vaporizer 14,and the humidlfier 16. It is
21 possible to use these components in combination with each other
22 or to use the components separately.
a3
24 The fuel expander 12 can readily be used alone in combi-
nation with the internal combustion engine 10 to increase the gas
26 milesge as indicated earlier in this speci~ication. Or, the vapor-
27 izer 14 can be used alone in combination with the carburetor 60
28 and the internal combustion engine 1~. For maximum efficiency in
29 the burning of fuel, it is advi able to use the expander 12, the
vaporizer 14, and the humidifier 16 in combinati~n. The humidifi-
31 cation of air for burning in an internal combl1stion engine as,
32 previously, explained is beneficial giving a more even burning of
- 1 9 -

the fuel in the internal combustion engine and a more complete
burning of the fuel in the internal combustion engine.
