Abstract

Abstract A fuel vaporizing device for use with a carburetor to more efficiently vaporize and distribute the fuel portion of the air/fuel mixture. The device is mounted between the carburetor and intake manifold and positions a hot plate element in the flow path of each carburetor barrel discharge. Each hot plate is comprised of a solid metal disk in which a plurality of through bores are formed. Heat is supplied by a conduit extending through the disk, but does not intersect any of the through bores. The conduit is connected to both the intake and exhaust manifolds so that hot exhaust gas passes therethrough at relatively high velocity. To assure uniform flows of exhaust gas, an exhaust reservoir is provided in the connecting line between the exhaust manifold and the vaporizing device.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 231 words
A fuel vaporizer for use in cooperation with at least a two barrel carburetor and a fuel supply for an engine comprising a mounting plate for positioning the vaporizer between the carburetor and an engine manifold, said mounting plate having means defining an open interior, said open interior including at least two circularly shaped recesses, a plate member means positioned within each of said at least two circularly shaped recesses, said plate member means including means defining a plurality of through bores, each of said plate member means being axially aligned with one of the barrels in the carburetor, said fuel vaporizer further including means defining a hollow conduit passing through said mounting plate and through each of said plate member means so as to avoid said through bores therein, said conduit means terminating at first and second ends, each of which extends outwardly beyond said mounting plate, said first end being connected to an engine exhaust system, said second end being connected to an engine air intake system so that exhaust gases flow from said exhaust system through said hollow conduit means and into said air intake system and wherein said first end further includes means defining a separate reservoir chamber positioned exteriorly of said mounting plate and operatively connected within said conduit means so as to serve as a reservoir for exhaust gas being drawn through said conduit means.
Claim 2
Dependent Claim 231 words
A fuel vaporizer for use in cooperation with at least a two barrel carburetor and a fuel supply for an engine comprising a mounting plate for positioning the vaporizer between the carburetor and an engine manifold, said mounting plate having means defining an open interior, said open interior including at least two circularly shaped recesses, a plate member means positioned within each of said at least two circularly shaped recesses, said plate member means including means defining a plurality of through bores, each of said plate member means being axially aligned with one of the barrels in the carburetor, said fuel vaporizer further including means defining a hollow conduit passing through said mounting plate and through each of said plate member means so as to avoid said through bores therein, said conduit means terminating at first and second ends, each of which extends outwardly beyond said mounting plate, said first end being connected to an engine exhaust system, said second end being connected to an engine air intake system so that exhaust gases flow from said exhaust system through said hollow conduit means and into said air intake system and wherein said first end further includes means defining a separate reservoir chamber positioned exteriorly of said mounting plate and operatively connected within said conduit means so as to serve as a reservoir for exhaust gas being drawn through said conduit means.
