Abstract
Abstract A vaporization chamber for an internal combustion engine, the engine having a liquid fuel reservoir and an intake manifold, the generator serving to convert liquid fuel to a combustible gas mixture including a vaporization chamber the outlet of which is connected to the engine intake manifold, a plurality of small diameter tubular reeds extending within the vaporization chamber and communicating with the inlet and means of introducing liquid fuel from the fuel reservoir and air through the reeds into the vaporization chamber.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
106 words
For an internal combustion engine having a liquid fuel reservoir and an intake manifold, a generator for converting liquid fuel to a combustible gas, comprising: a vaporization chamber having an outlet and an inlet, the outlet being connected to the engine intake manifold; a plurality of small diameter spaced apart independently vibratable tubular reeds extending within said vaporization chamber and communicating with said inlet; and means of introducing liquid fuel from the reservoir and air through a passage located within each of said reeds into said vaporization chamber, the reeds being dimensioned so that they vibrate harmonically by the effect of fuel and air passing therethrough.
Claim 2
Dependent Claim
106 words
For an internal combustion engine having a liquid fuel reservoir and an intake manifold, a generator for converting liquid fuel to a combustible gas, comprising: a vaporization chamber having an outlet and an inlet, the outlet being connected to the engine intake manifold; a plurality of small diameter spaced apart independently vibratable tubular reeds extending within said vaporization chamber and communicating with said inlet; and means of introducing liquid fuel from the reservoir and air through a passage located within each of said reeds into said vaporization chamber, the reeds being dimensioned so that they vibrate harmonically by the effect of fuel and air passing therethrough.
Claim 3
Dependent Claim
33 words
A combustion gas generator according to claim 1 including: means of simultaneous variably controlling the quantity of combustible gas from said generator and the quantity of air passing into the engine intake manifold.
Claim 4
Dependent Claim
21 words
A combustion gas generator according to claim 1 wherein the reeds are from about 1.75 to about 5 inches in length.
Claim 5
Dependent Claim
23 words
A combustion gas generator according to claim 1 wherein the length of said reeds are of variable length between 1.75 and 5 inches.
Claim 6
Dependent Claim
36 words
A combustion gas generator according to claim 1 wherein said reeds are of metal, are thin walled, are of length between about 1.75 and 5 inches and inside diameter of about 0.001 to about 0.0076 inches.
Claim 7
Dependent Claim
74 words
A combustion gas generator according to claim 1, said inlet in said vaporization chamber comprises: an opening in said vaporization chamber; a metal plug received in and closing said opening, the plug having an opening therethrough for each said reed, and one each of said reeds being received in a said opening; and a layer of hard epoxy received on the interior surface of said plug and surrounding each of said reeds extending therefrom.
Claim 8
Dependent Claim
17 words
A combustible gas generator according to claim 1 including: means for evacuating liquid from said vaporization chamber.
Claim 9
Dependent Claim
59 words
A combustible gas generator according to claim 7 wherein said means for evacuating liquid from said vaporization chamber comprises: a liquid collection vessel having an inlet and outlet; a conduit connecting the collection vessel inlet to a lower portion of said vaporization chamber; and means of conducting liquid fuel out of said collection vessel to the liquid fuel reservoir.
Claim 10
Dependent Claim
52 words
A combustion gas generator according to claim 8 including: a liquid level detector means in said collection vessel; an electrically controlled solenoid valve in said conduit between said vaporization chamber and said collection vessel; and means of opening said control valve when the liquid in said collection vessel reaches a preselected level.
