TECHNICAL FIELD

[0001] The present invention generally relates to internal combustion engines, and more particularly relates to airflow enriching devices utilizing the bubbling of air through a liquid fuel source to create an enriched airflow for combustion in an internal combustion engine.

BACKGROUND OF THE INVENTION

[0002] Due to the ever rising price of gasoline and the continued popularity of motor vehicles as a mode of transportation, much effort in the prior art has been directed to increasing the efficiency of internal combustion engines. In addition, and often to the detriment of increasing the efficiency of internal combustion engines, further efforts in the prior art have been directed toward reducing the various pollutants emitted from motor vehicles. Needless to say, the prior art includes many different approaches to the problems of increasing the efficiency of internal combustion engines and for reducing the pollutants thereof.

[0003] A carburetor is a device that blends air and fuel for an internal combustion engine. The typical carburetor utilizes suction created by intake air accelerated through a Venturi tube to draw fuel into the internal combustion engines airstream for burning. A fuel injection system is a system for admitting fuel into an internal combustion engine by atomizing fuel by forcibly pumping it through a small nozzle under high pressure.

[0004] The primary problem with carburetors and fuel injector systems is that they are inadequate in breaking the fuel into small enough droplets. This results in the presence of relatively large droplets of fuel which will not completely vaporize in the intake manifold and/ or engine. The result is low engine operating efficiency with formation of carbon monoxide and high hydrocarbon emissions. It therefore becomes desirable to produce a carburetor/fuel injector system improvement that will break up the larger droplets of fuel and disperse them more evenly, increasing the efficiency of the engine by burning more of the fuel.

[0005] The prior art knows many different means of atomizing and vaporizing the fuel. One type of such a vaporization system uses a source of air which is bubbled through a reservoir of liquid gasoline, the resulting vapors being inputted into the combustion chamber of the engine. Various patents exist for similar types of devices, for instance, U.S. Pat. Nos. 474,838, 1,938,497, 3,749,376, and 4,011,847. SUMMARY OF THE DISCLOSURE

While internal combustion engines are envisioned as the likely use of such devices, it may also be able to be used on gasoline turbine engines, rotary type engines, and with any other manner of combusting liquid fuel.

[0049] Referring initially to Figure 1, a first exemplary airflow enriching device 10 is illustrated in general schematic format.

[0050] This exemplary airflow enriching device 10 is configured to be utilized with an internal combustion engine system. While this exemplary airflow enriching device 10 is so configured, a skilled artisan will be able to select an appropriate structure and configuration for an exemplary device in a particular embodiment based on various considerations, including the type of engine or motor with which it will be used.

[0051] In this exemplary airflow enriching device 10, a fuel tank 12 containing a supply of fuel is provided. A pump 16 is utilized to pump the fuel, preferably through a filter 14, from the fuel source (e.g., a fuel tank) 12, through a fuel inlet port 28, and to the reaction chamber 36 of the device 10. The filter 14 may be located between the fuel tank and the pump 16 (as illustrated), or the filter 14 may be located at another location between the pump 16 and the intake manifold 31 of the engine. Other means of supplying the airflow enriching device 10 with fuel are also envisioned, and many are well known to the public knowledge, including, but not limited to vacuum, gravity, etc.

[0052] The vaporization of fuel will typically result in the evaporative cooling of the fuel remaining in the reaction chamber 36. To maintain process efficiency, either incorporated into the device 10 itself or inline between the fuel tank 12 and the device 10, a heater 26 for heating the fuel may be utilized. It is preferred that the heater 26 not cause the fuel to boil, but instead keep the fuel at a temperature of between about 100°F (38°C) and about 130°F (54.5°C), more preferably about 120°F (49°C). Examples of heaters include, but are not limited to, a heating element located in the level of liquid fuel, an inline heater, and utilizing heat from the cooling system of the engine. It is preferred that the heating element or portion of the unit provide for a constant working temperature to enable the other elements of the unit to separate the molecular bonds that hold the hydrocarbons together. Alternatively, a heater could be wrapped around the reaction chamber. While it is preferred that the fuel not be boiled, other exemplary devices may utilize the cold boiling of the fuel.

[0053] It is preferred that the airflow enriching device 10 utilize a sensor 18 for sensing the level of fuel contained within the airflow enriching device 10. The sensor 18 measuring the level of fuel contained within the reaction chamber 36 of the airflow enriching device 10. Upon the sensor 18 detecting a level of fuel at or below a predetermined depth, the airflow enriching device 10 can, via fuel pump 16 pumping fuel through fuel inlet port 28 or other means, add fuel to the reaction chamber 36.

[0054] Attaching to the reaction chamber 36 is an air supply 24, preferably a vacuum regulated air source or a pneumatic system, for supplying a flow of air to the airflow enriching device 10. This supplied air is bubbled through the fuel contained within the reaction chamber 36 to create an enriched airflow containing fuel vapors. The enriched airflow flows out of the reaction chamber 36 through an outlet 19.

[0055] Connecting at the outlet 19 is a conduit 20, such as a supply line, for fluidly connecting the reaction chamber 36 with a vapor flow controller 25, thereby supplying enriched airflow to the vapor flow controller 25. The vapor flow controller 25 for regulating the flow of enriched airflow into the intake manifold 31 of the engine.

[0056] Referring now to Figures 2, 3, 4 and 5, illustrated is a second exemplary airflow enriching device 100 which could be used with the first exemplary vapor flow controller illustrated in Figures 6 through 15 or another exemplary vapor flow controller. In this exemplary airflow enriching device 100, a fuel tank containing a supply of fuel is provided. A pump is utilized to pump the fuel through a fuel inlet port 133, and into a reaction chamber 136. Other means of supplying the airflow enriching device 100 with fuel are also envisioned, and many are well known to the public knowledge, including, but not limited to vacuum, gravity, etc.

[0057] The illustrated reaction chamber 136 comprising a canister portion 137 and a lid portion 132. The canister portion 137 is an open topped vessel defining an internal space for holding a volume of fuel 121 having a surface level 122 therein. The lid portion 132 encloses the internal space. In the exemplary reaction chamber 136 illustrated in these figures, the lid portion 132 connects to the canister portion 137 via a clamp 119, and an O-ring 101 is utilized as a seal between the canister portion 137 and the lid portion 132. In other exemplary reaction chambers the reaction chamber could be a single piece (no separate lid portion), or otherwise configured.

[0058] In the exemplary reaction chamber 136 illustrated in these figures, the lid portion 132 comprises an air supply inlet port 128, an outlet port 146, and a number of accessory ports (e.g., sensor port 130 for receiving a sensor 131 therein, a fuel inlet port 133, an auxiliary port 135). While these ports are illustrated as being defined in the lid portion 132, in other exemplary airflow enriching devices/systems, the ports may or may not be present, and if present may located in the lid portion, in the reaction chamber, or in another location. A skilled artisan will be able to select an appropriate structure, configuration, and location for the ports in a particular embodiment based on various considerations, including the intended use of the device, the intended arena within which the device will be used, and the equipment and/ or accessories with which the device is intended to be used, among other considerations.

[0059] The exemplary reaction chamber 136 of these figures further comprises mounting brackets (155, 156) for allowing the airflow enriching device 100 to be mounted within the engine compartment of the vehicle, or another location, via a suitable fastener such as a bolt. Such mounting brackets are optional, and these exemplary mounting brackets are merely one example of a possible configuration.

[0060] While the illustrated reaction chamber 136 is generally cylindrical in shape, a skilled artisan will be able to select an appropriate shape for the reaction chamber in a particular embodiment based on various considerations, including the equipment and/or accessories with which the reaction chamber is intended to be used, among other considerations.

[0061] In this exemplary reaction chamber 136, located within the reaction chamber 136 is an air supply line 134. The air supply line 134 has a first end which fluidly connects the air supply inlet port 128 which is fluidly connected to an air supply generating airflow 140. It is preferred that the airflow 140 come from a regulated source, such as a vacuum regulator 127. It is preferred that the vacuum regulator 127 be adjustable, for allowing an operator to adjust the vacuum pressure within the reaction chamber 136 and airflow enriching device 100 as desired. It is preferred that the vacuum contained within the reaction chamber 136 be maintained at no lower than 8.00 inHg (203.2 mmHg), with a more preferred range of between 8.00 inHg (203.2 mmHg) and 10.00 inHg (254 mmHg). Higher settings (higher than 10.00 inHg (254 mmHg)) and lower settings (lower than 8.00 inHg (203.2 mmHg)) are possible, but are less preferred.

[0062] The air supply line 134 has a second end which fluidly connects with an aerator 150 so that the air supply can be utilized to produce a stream of bubbles within the volume of fuel 121. In the exemplary aerator 150 illustrated, the aerator 150 comprises a top plate 151, an O-ring 103, and a bottom plate 152, the top plate 151 and the bottom plate 152 defining a chamber 158 therebetween. The O-ring 103 for sealing the connection between the top plate 151 and the bottom plate 152. While such an aerator 150 is illustrated in the drawings, a skilled artisan will be able to select an appropriate structure and configuration for an aerator in a particular embodiment based on various considerations, including the intended use of the airflow enriching device, the fuel utilized, the temperature and pressure used, and the equipment and/ or accessories with which the airflow enriching device is intended to be used, among other considerations.

[0063] One or more air outlets 157 are defined through the air supply line 134 for allowing the air supply line 134 to fluidly connect with the aerator 150, for instance connecting to the chamber 158 defined between the top plate 151 and the bottom plate 152. The top plate 151 and the bottom plate 152 having a plurality of bubbler holes defined therethrough. The bubbler holes 159 for allowing the supply of air passing through the air supply line 134 and into the chamber 158 to be bubbled through the fuel 121 held within the reaction chamber 136, thereby aerating the fuel.

[0064] In use, the aerator 150 is submerged below the surface level 122 of the fuel 121. As airflow 140 passes through the aerator 150, bubbles 138 bubble out the aerator 150 and through the fuel 121, resulting in an expansion of the fuel through use of vacuum energy, creating a fuel vapors 139 (aka vaporized fuel mist, expanded fuel, atomized fuel) and an enriched airflow 160 within an air-fuel vapor mixing chamber 154. Heating the fuel (optionally) may be utilized to supplement this expansion process.

[0065] Optionally, a mist barrier (not illustrated) can be utilized within the reaction chamber to inhibit the transfer to the carburetor/fuel injection system of mist particles that have not expanded to gas. These mist particles will then settle and be later expanded into gas state. It is preferred that the mist barrier be comprised of a material that is not effected by gasoline, fuels and/ or fuel additives likely to be utilized with the present invention.

[0066] As necessary, liquid fuel is supplied to the reaction chamber 136 through use of a fuel inlet port 133. A sensor 118, extending through a sensor port 115, or otherwise located, can be utilized to sense the level of fuel 121 within the reaction chamber 136, enabling additional fuel 121 to be added to the reaction chamber 136 via fuel inlet port 133, or another source, when a fuel level that is lower than a predetermined level is sensed. In this embodiment, the sensor 118 comprises an electronic sensor eye. In the exemplary reaction chamber illustrated in Figure 2, the port 115 is defined through the sidewall of the reaction chamber 136, approximately two inches (five centimeters) above the bottom of the reaction chamber 136, and the sensor 118 is illustrated as extending through this port. Control of the level of fuel is useful to provide a minimum depth of fuel within the reaction chamber, preferably at a level at least deep enough to keep the bubbler holes 159 of the aerator 150 submerged.

[0067] The bubbles 138 and pressure cause the atomization and vaporization of the fuel 121 present within the reaction chamber 136 to form an enriched airflow 160 containing fuel vapors 139. The enriched airflow 160 leaves the reaction chamber 136 through an outlet port 146. This outlet port 146 fluidly connecting with a vapor flow controller 125 via an inlet conduit 165, thereby supplying enriched airflow 160 to the vapor flow controller 125. The vapor flow controller 125 for regulating the flow of enriched airflow into the engine, preferably the intake manifold of the engine.

[0068] As illustrated in Figures 5 and 6, the inlet conduit 165 having a first connector 164 for fluidly connecting with the outlet port 146, and a second connector 166 for fluidly connecting with the inlet port 126 of the vapor flow controller 125. While such fittings and connections are illustrated with respect to this exemplary device, a skilled artisan will be able to select an appropriate connection structure and material in a particular embodiment based on various considerations, including the intended use of the airflow enriching device, the intended arena within which the airflow enriching device will be used, and the equipment and/ or accessories with which the airflow enriching device is intended to be used, among other considerations.

[0069] The vaporization of fuel may result in the evaporative cooling of the fuel remaining in the reaction chamber 136. To maintain process efficiency, either incorporated into the airflow enriching device 100 itself or inline between the fuel tank and the airflow enriching device 100, a heater for heating the fuel may be utilized, as described above regarding the exemplary airflow enriching device of Figure 1.

[0070] Referring now to Figures 6 through 15, illustrated is a first exemplary vapor flow controller 125. The vapor flow controller 125 comprising a vapor flow control valve 124 and an actuator 129. The vapor flow controller 125 for controlling flow of enriched airflow 160 from the airflow enriching device 100 into the engine.

[0071] The vapor flow control valve 124 comprises an inlet port 126 which flu idly connects with the reaction chamber 136 via inlet conduit 165. The vapor flow control valve 124 further comprising a passageway 190 extending between the inlet port 126 and an outlet port 198. The outlet port 198 fluidly connects with an outlet conduit 194 (such as via outlet connector 192) for supplying the enriched airflow 160 to the engine. For instance, as illustrated in Figure 6, a throttle body spacer 195 could be provided, the throttle body spacer 195 comprising an inlet port 197 therethrough into an internal passage 193. A connector 199 or other fitting could be used to fluidly connect the outlet conduit 194 with the inlet port 197. The throttle body spacer 195 configured for attachment to the engine's air-intake system, for instance, downstream of the throttle body between the intake manifold and throttle body, or upstream of the throttle body. A skilled artisan will be able to select an appropriate location for the throttle body spacer 195 or other manner of fluidly connecting the airflow enriching device 100 with the engine's air-intake system in a particular embodiment based on various considerations, including the equipment and/or accessories with which the airflow enriching device 100 is intended to be used, among other considerations.

[0072] The vapor flow control valve 124 further comprising a valve 170 for interrupting the passageway 190, enabling the flow of enriched airflow 160 to be turned on, increased, decreased, and turned off. [0073] In the exemplary vapor flow controller 125 illustrated in the figures, the valve 170 comprises a piston 180 which is in slidable engagement with the passageway 190. While this type of valve is illustrated herein, a skilled artisan will be able to select an appropriate structure, type and configuration for the valve in a particular embodiment based on various considerations, including the intended use of the valve, among other considerations, including but not limited to plug valves, piston valves, ball valves, gate valves, globe valves, needle valves, stopcock valves, spool valve, and butterfly valves.

[0074] The piston 180 configured for slidably engaging the passageway 190. The piston 180 having an external surface comprising at least one lateral groove 182 defined therein.

[0075] The valve 170 having a closed position which is illustrated in Figures 11 and 13, and open positions which are illustrated in Figures 12, 14 and 15. In the closed position, the piston 180 is inserted into the passageway 190 thereby stopping up the passageway 190. In the open positions, the piston 180 is withdrawn from the passageway 190 so that one or more of the lateral grooves 182 are exposed, enabling enriched airflow 160 to pass from one side of the valve 170 to the other side of the valve.

[0076] In the exemplary vapor flow controller 125 illustrated in these figures, the piston 180 is moved from the closed position to the open positions (and back to the closed position) through use of the actuator 129. The exemplary actuator 129 illustrated in the figures having a rotatable shaft 186. The piston 180 connecting to the actuator 129 via an arm 184 connecting to the shaft 186. The actuator 129 rotates the shaft 186, which is translated into lateral motion of the piston 180 via the arm 184, moving the piston 180 from the open position to the closed position (and vice versa). It is preferred that the piston 180 be hingedly connected to a first end of the arm 184 and that the shaft 186 be hingedly connected to a second end of the arm 184.

[0077] The opening and closing of the valve 170 serves to vary the pressure within the airflow enriching device 100, and allows (in the open positions) enriched airflow 160 to be drawn into the engine. The actuator 129 further comprising an outlet port 198 defined in an end plate 196, the outlet port 198 configured for fluid connection with the engine. For instance, the outlet port 198 could connect, via a conduit 194, to a connector attached in-line with the intake manifold (for instance, between the intake manifold and the throttle body), thereby enabling enriched airflow 160 to be drawn into the intake manifold of the engine. While this is one such manner of feeding the enriched airflow into the engine, a skilled artisan will be able to select an appropriate structure and material for the connection in a particular embodiment based on various considerations, including the intended use of the airflow enriching device, the intended arena within which the airflow enriching device will be used, and the equipment and/or accessories with which the airflow enriching device is intended to be used, among other considerations.

[0078] In engines utilizing a fuel injection system (a "fuel injected engine"), the "throttle body" is the part of the air intake system that controls the amount of air flowing into the engine, typically in response to driver accelerator pedal input in the main. The throttle body is usually located between the air filter box and the intake manifold. A throttle body is somewhat analogous to the carburetor in a non-fuel injected engine. A typical throttle body will have a rotatable shaft connected to a throttle plate, comprising a butterfly valve that regulates the airflow. Typically, accelerator pedal motion is utilized to determine how much the throttle body's butterfly valve should be open, allowing more (or less) air into the intake manifold.

[0079] It is preferred that the actuator 129 comprise a throttle body which is the same as, or is similar to, the existing engine throttle body, such a throttle body electronically controlled by the vehicle's computer system. It is further preferred that the actuator 129 be electronically connected into the vehicle's electrical and computing systems in parallel with the existing throttle body, so that the two components work in tandem. For instance, a split connector, a Y-splitter, or other wiring connection could be used to electronically connect the throttle body and actuator 129 in parallel.

[0080] In the exemplary airflow enriching device 100 illustrated in Figures 6 through 15, the actuator 129 can comprise the same or similar make and model of throttle body already being used on the engine. Such a throttle body being converted for use in the vapor flow controller 125 by connecting the vapor flow controller 125 to one side, and an end plate 196 to the other end. The outlet port 198 is preferably defined through the end plate 196.

[0081] The butterfly valve portion of the throttle body would be removed from the shaft 186. In this exemplary throttle body, the shaft 186 comprises a channel 183 therein to which the butterfly valve portion connects. The butterfly valve portion is replaced with a suitable connector, such as connector 185 having a tongue 187 for insertion into the channel 183. At least one fastener 181 utilized to fix the tongue 187 into the channel 183. The connector 185 pivotally attached to the arm 184, which is in turn pivotally attached to the piston 180.
