Abstract
Abstract A gasoline refractionator for internal combustion engines has a first heat exchanger which receives gasoline from a fuel source and cools the gasoline sufficiently to cause the gasoline to separate into its lighter and heavier ends or components. The separated components are then heated in a second heat exchanger to a temperature at which the components will tend to remain separated even when in physical contact with one another. By imparting a swirl to the heated components, the heavier components will tend to surround the lighter components and provide maximum surface contact between the components during ignition in a cylinder of an internal combustion engine.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
77 words
A method of stratifying gasoline into lighter and heavier components prior to entrance of the gasoline into a combustion chamber of an internal combustion engine, comprising the steps of: a. cooling the gasoline to a temperature wherein settling of the gasoline into layers of lighter and heavier components occurs and separating the components; and b. heating the separated components to a temperature at which the components tend to remain separated when in physical contact with one another.
Claim 2
Independent Claim
77 words
A method of stratifying gasoline into lighter and heavier components prior to entrance of the gasoline into a combustion chamber of an internal combustion engine, comprising the steps of: a. cooling the gasoline to a temperature wherein settling of the gasoline into layers of lighter and heavier components occurs and separating the components; and b. heating the separated components to a temperature at which the components tend to remain separated when in physical contact with one another.
Claim 3
Dependent Claim
82 words
A method as set forth in claim 1, wherein the heating step (b) includes the steps of placing the heated components in contact with one another along a flow path, and imparting a swirl to the heated components for bringing the heavier components outside and surrounding the lighter components and concentrating the lighter components near the center of the flow path for allowing intense heat of ignition of the lighter components to contact and ignite a great percentage of the heavier components.
Claim 4
Dependent Claim
28 words
A method as set forth in claim 2, wherein the heating step (b) further includes the step of dividing the components into different flow paths during the heating.

Dependent Claim
27 words
A method as set forth in claim 1, wherein the heating step (b) includes the step of dividing the components into different flow paths during the heating.
Claim 7
Dependent Claim
39 words
A method as set forth in claim 1, wherein the cooling step (a) includes the step of cooling the gasoline substantially 10° F., and the heating step (b) includes the step of heating the components to substantially 160° F.
