Fuel gasification for internal combustion engines

Claim 3

The system of claim 1 including a preheating chamber adjacent said gasification chamber said exhaust conducting means having a first branch connecting the exhaust manifold of said engine to said preheating chamber for preheating said gasification, and a second branch connecting said preheating chamber to said gasification for directing the exhaust gases directly to said gasification to intimately mix with and gasify said liquid fuel by direct heat transfer therebetween.

Claim 4

The system of claim 2 including an air preheater operatively connected to said gasification whereby a portion of the exhaust gases directed to said gasifying means is utilIzed to preheat air, and means directing said preheated air to said gasification to intermingle and impart heat to said liquid fuel within said chamber.

Claim 5

The system of claim 3 including an air preheater means connected to said second branch whereby a portion of the exhaust gases flowing therethrough is tapped to supply heat to said air heater means, and a hot air line connecting said air preheater to said gasification for directing the preheated air to said gasification.

Claim 6

The system of claim 2 including an auxiliary heater for imparting heat to said gasification to effect gasification of said liquid fuel on start up.

Claim 7

A carburetor for use with an internal combustion engine having an exhaust manifold and a fuel inlet, said carburetor being capable of using low-grade liquid fuel and effecting the gasification thereof prior to the distribution of said fuel to said engine, said carburetor means including gasification chamber, a fuel conduit connected to said chamber for introducing liquid into said chamber in predetermined amounts, an exhaust conduit connected between said exhaust manifold and said gasification chamber, said exhaust conduit being connected between said exhaust manifold and said gasification chamber for direct mixing with said fuel, an air preheater, said air preheater including a tap conduit off said exhaust conduit for tapping off a portion of the exhaust gases flowing therethrough, an air heating coil disposed in heat transfer relationship about said tap conduit, an air line connecting the outlet of said air preheater to said gasification chamber, means disposed in said exhaust conduit means and hot air line to control the flow of the respective heated gases flowing therethrough, a fuel conductor for directing the gasified fuel mixture from said gasification chamber to said engine fuel inlet, a combustion air supply disposed in communication with said fuel conductor, and means disposed within said fuel conductor for mixing combustion air with said gasified fuel mixture to form a combustible fuel mixture, said means utilizing the negative pressure developed by the engine.

Claim 8

A carburetor for use with an internal combustion engine having an exhaust manifold and a fuel inlet, said carburetor being capable of using low-grade liquid fuel and effecting the gasification thereof prior to the distribution of said fuel to said engine, said carburetor means including gasification chamber, a fuel conduit connected to said chamber for introducing liquid into said chamber in predetermined amounts, an exhaust conduit connected between said exhaust manifold and said gasification chamber, said exhaust conduit being connected between said exhaust manifold and said gasification chamber for direct mixing with said fuel, an air preheater, said air preheater including a tap conduit off said exhaust conduit for tapping off a portion of the exhaust gases flowing therethrough, an air heating coil disposed in heat transfer relationship about said tap conduit, an air line connecting the outlet of said air preheater to said gasification chamber, means disposed in said exhaust conduit means and hot air line to control the flow of the respective heated gases flowing therethrough, a fuel conductor for directing the gasified fuel mixture from said gasification chamber to said engine fuel inlet, a combustion air supply disposed in communication with said fuel conductor, and means disposed within said fuel conductor for mixing combustion air with said gasified fuel mixture to form a combustible fuel mixture, said means utilizing the negative pressure developed by the engine.

Claim 9

The carburetor of claim 6 including an auxiliary heater for imparting heat to said liquid fuel within said gasification chamber for effecting the gasification of said liquid fuel on start up.

Claim 10

The carburetor of claim 6 including a heating chamber juxtaposed adjacent said gasification chamber, and said exhaust conduit serially flowing a portion of the exhaust through said heating chamber and to said gasification chamber whereby said exhaust gases mix with and heat said liquid fuel to form a gaseous mixture.
