Abstract
Abstract Method and device for dissolving gas, especially carbon dioxide or compressed air, in liquid subject to conditions of pressure and temperature at which, when the solution is subsequently introduced into the combustion air, it will be in a supersaturated state and accordingly finely disperses and distributes itself uniformly. The fuel is forced by a pump (41) into the mixer (11), to which the gas is supplied through a flow regulator (29). Downstream of the mixer (11) are a turbulent section (163), a mixing dome (161), and an exhaust section (164) from which the solution is supplied free of bubbles to the carburetor or injector of an internal-combustion engine, a heating burner, or a reaction-engine burner. The flow regulator (29) is controlled in accordance with the throughput of fuel and regulated by a regulation device (R) in accordance with the percentage of gas in the mixing dome (161) as determined by a pressure gauge (46) or light sensor (51).

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
89 words
In a method of distributing liquid fuel in combustion air at a certain mixing pressure and temperature mixed into it by a carburetor or injector into a combustion chamber or zone, the improvement comprising dissolving a gas from an external source in the fuel to produce a solution external to said combustion chamber or zone, providing a solution temperature at ambient temperature and a solution pressure greater than atmospheric at which a higher gas solubility of the gas is ensured supplying the liquid solution to the carburetor or injector.
Claim 2
Dependent Claim
89 words
In a method of distributing liquid fuel in combustion air at a certain mixing pressure and temperature mixed into it by a carburetor or injector into a combustion chamber or zone, the improvement comprising dissolving a gas from an external source in the fuel to produce a solution external to said combustion chamber or zone, providing a solution temperature at ambient temperature and a solution pressure greater than atmospheric at which a higher gas solubility of the gas is ensured supplying the liquid solution to the carburetor or injector.
Claim 3
Dependent Claim
19 words
The method as in claim 1, wherein the solution is completely saturated with the gas at the solution temperature.
Claim 4
Dependent Claim
32 words
The method as in claim 1, wherein the solution pressure is several atmospheres above the combustion air mixing pressure and the solution temperature is not greater than the combustion air mixing temperature.
Claim 5
Dependent Claim
54 words
The method as in claim 1, further comprising providing the combustion air mixing temperature higher than the solution temperature by adding combustion heat in the form of radiation from the combustion zone or from walls of the combustion chamber and providing the solution pressure and combustion air mixing pressure not greater than normal pressure.
Claim 6
Dependent Claim
121 words
The method as in claim 1, further comprising constantly supplying the fuel and the gas regulated in the specified quantitative ratio to a vertically positioned gas/fuel mixer with a turbulent section located above it and with a gas/fuel mixing dome located above the turbulent section, thereafter diverting same into a separating section that is oriented downward and supplying from its bottom the solution to the carburetor or injector, wherein the turbulent section is dimensioned so that the stream of gas bubbles is extensively dissolved before it arrives at the gas/fuel mixing dome and the cross-section of the separating section is dimensioned so that the speed at which the fuel solution falls is lower than that at which the gas bubbles rise.
Claim 7
Dependent Claim
23 words
The method as in claim 1, wherein the gas has a property of least one of dissolves readily, burns readily and is oxidizing.
Claim 8
Dependent Claim
31 words
The method as in claim 1, wherein the fuel is selected from methyl alcohol, ethyl alcohol, gasoline, benzene, heating oil, diesel oil, heavy oil, and a mixture of fuel and pollutant.
Claim 9
Independent Claim
77 words
A device for mixing liquid fuel in combustion air by feeding the fuel and air to a carburetor or injector at a mixing temperature and pressure, comprising means dissolving gas into the fuel and air at a solution temperature at ambient temperatures and at a solution pressure greater than atmospheric at which a higher gas solubility of the gas is ensured, said means for dissolving said gas in said fuel being external to said carburetor or injector.
Claim 10
Independent Claim
77 words
A device for mixing liquid fuel in combustion air by feeding the fuel and air to a carburetor or injector at a mixing temperature and pressure, comprising means dissolving gas into the fuel and air at a solution temperature at ambient temperatures and at a solution pressure greater than atmospheric at which a higher gas solubility of the gas is ensured, said means for dissolving said gas in said fuel being external to said carburetor or injector.
Claim 11
Dependent Claim
56 words
The device as in claim 8, further comprising a cylindrical pipe containing a turbulent section positioned downstream of a gas/fuel mixer and having a height that is twice its diameter and a cylindrical glass housing is positioned concentric to the pipe to form a separating section with a solution delivery line connected to its lower section.
Claim 12
Dependent Claim
33 words
The device as in claim 8, wherein the fuel is supplied from a tank to the dissolving means through a filter and a check valve, and wherein a pump supplies the solution pressure.
Claim 13
Dependent Claim
42 words
The device as in claim 8, further comprising means supplying a the gas via line fed by a pressure tank through a reduction valve to deliver the gas at the solution pressure and followed by a flow regulator to the dissolving means.
Claim 14
Dependent Claim
80 words
The device as in claim 11, wherein the flow regulator has a control input connected to a regulator connected on its input side with a sensor for indicating the intensity of a stream of bubbles of the gas in the gas/fuel mixing dome and has regulation means for controlling the flow regulator wherein a signal from the sensor is compared with a given reference value and the resulting differential signal is fed as a control signal to the flow regulator.
Claim 15
Dependent Claim
48 words
The device as in claim 12, wherein a fuel-return line leading to a tank is positioned at the gas/fuel mixing dome with a flow regulator that is turned on by the control means when the sensor indicates the pressure of a large gas bubble in the mixing dome.
Claim 16
Dependent Claim
21 words
Internal-combustion engine comprising the device of claim 10 and wherein the gas is dissolved in the fuel downstream of the pump.
