Abstract
Abstract A reaction carburetor for an internal combustion engine which operates to catalytically convert fuel from the liquid to the gaseous state for improved combustion. According to the invention, means are provided for stabilizing the flow of fuel and air in the carburetor. The stabilizing means include at least one temperature-stable body, arranged in the fuel-air flow path ahead of the catalyst, having a plurality of flow channels extending therethrough in the direction of the flow path.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
92 words
In a reaction carburetor, containing at least one catalyst arranged in the flow path of a fuel-air mixture, for catalytic conversion of fuel from the liquid to the gaseous state, the improvement comprising means for stabilizing the flow in said carburetor, said stabilizing means including at least one temperature-stable, non-catalytically active body arranged in the said flow path immediately ahead of said catalyst and having a plurality of flow channels extending therethrough in the direction of said flow path and of sufficient length to create substantially laminar flow of said fuel-air mixture.
Claim 2
Dependent Claim
92 words
In a reaction carburetor, containing at least one catalyst arranged in the flow path of a fuel-air mixture, for catalytic conversion of fuel from the liquid to the gaseous state, the improvement comprising means for stabilizing the flow in said carburetor, said stabilizing means including at least one temperature-stable, non-catalytically active body arranged in the said flow path immediately ahead of said catalyst and having a plurality of flow channels extending therethrough in the direction of said flow path and of sufficient length to create substantially laminar flow of said fuel-air mixture.
Claim 3
Dependent Claim
24 words
The improvement defined in claim 1, wherein said body is made essentially of a ceramic material having a high wetting ability for liquid fuel.
Claim 4
Dependent Claim
18 words
The improvement defined in claim 1, wherein said body is made essentially of a ceramic, aluminum silicate-fiber material.
Claim 5
Dependent Claim
35 words
The improvement defined in claim 1, wherein said body is essentially cylindrically shaped with said flow channels formed in its axial direction, the cross-section of said cylindrical body corresponding to the cross-section of said catalyst.
Claim 6
Dependent Claim
18 words
The improvement defined in claim 1, wherein said body is molded and said flow channels are stamped therein.
