Abstract
A fuel expansion system or carburetor for internal combustion engines utilizing the bubbling of air through use of a number of bubble tubes through a supply of liquid fuel. The resulting atomized, vaporized and expanded fuel is then mixed with air and fed into the engine for combustion.
Claims10
A fuel enriching carburetor device for an internal combustion engine, said device comprising:
- a reaction chamber operable to hold a supply of liquid fuel at a selected level therein, said reaction chamber provided with a plurality of generally vertically extending air tubes;
- said air tubes having a first end extending to a second end, said first end fluidly connected to a source of air, said source of air regulated through use of a vacuum regulator, said second end submerged below said selected level of liquid fuel;
- said reaction chamber defining an air-fuel vapor chamber, said air-fuel vapor chamber connecting to at least one air-fuel vapor mixing conduit in fluid communication between the air-fuel vapor chamber of said reaction chamber and an intake manifold of said engine;
- and said air-fuel vapor mixing conduit for delivering a supply of air-fuel mixture to the engine, said air-fuel vapor mixing chamber further comprising an air-fuel ratio inlet valve means for controlling airflow into said air-fuel vapor mixing conduit.

A fuel enriching carburetor device for an internal combustion engine, said device comprising:
- a reaction chamber operable to hold a quantity of liquid fuel at a selected level therein, said reaction chamber provided with a plurality of generally vertically extending air tubes, said air tubes having a first end extending to a second end, said first end fluidly connected to a source of air, said source of air regulated through use of a vacuum regulator, said second end submerged below said selected level of liquid fuel so that air supplied through said air tubes is bubbled through said quantity of liquid fuel, the bubbling of said air through said level of fuel resulting in the vaporization of said fuel, and further the expansion of said fuel;
- and
- a preheater for heating said quantity of liquid fuel;
- wherein said reaction chamber further defining an air-fuel vapor chamber, said air-fuel vapor chamber connecting to at least one air-fuel vapor mixing conduit in fluid communication between the air-fuel vapor chamber of said reaction chamber and an intake manifold of said engine, said air-fuel vapor mixing conduit provided with a mixing valve for controlling air-fuel ratio provided to the engine, said air-fuel mixing chamber further comprising an air-fuel ratio inlet valve means for controlling airflow into said air-fuel vapor mixing conduit.
