Abstract
Abstract A gaseous fuel-enriching subsystem for an internal combustion engine includes a supplemental intake conduit to a an intake manifold internal combustion engine. Such supplemental input is provided with numerus apertures therein. An exhaust gas conduit from the internal combustion engine annularly surrounds the intake conduit permitting fuel values from exhaust in the exhaust conduit to enter the supplemental intake conduit through such apertures. A water supply input to the supplemental intake conduit, at a end opposite to the location of the manifold, provides a further fuel input to the supplemental intake conduit in that water from the water supply is evaporated and then hydrolyzed, separating the water into its chemical constituents of hydrogen and oxygen, thusly producing an enriched gaseous fuel mixture with the recycled exhaust gas which is fed to the manifold.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
151 words
A gaseous fuel enriching subsystem for an internal combustion engine comprising: (a) a supplemental intake conduit to an intake manifold of said internal combustion engine, said conduit having a multiplicity of apertures therein; (b) an exhaust gas conduit from said internal combustion engine, said conduit annularly surrounding said intake conduit in which gaseous exhaust from said exhaust conduit is through said apertures, maintained in fluid communication with an interior of said supplemental intake conduit; and (c) a water supply input to said supplemental intake conduit at an end of said conduit opposite to said intake manifold, whereby thermal values from said exhaust gas conduit, imparted to said supplemental intake, will elevate the temperature of said water, firstly evaporating the same and subsequently, hydrolyzing said water prior to its entry into said manifold, this producing a gaseous mixture with fuel value of said exhaust as entering said supplemental intake through said apertures.
Claim 2
Dependent Claim
151 words
A gaseous fuel enriching subsystem for an internal combustion engine comprising: (a) a supplemental intake conduit to an intake manifold of said internal combustion engine, said conduit having a multiplicity of apertures therein; (b) an exhaust gas conduit from said internal combustion engine, said conduit annularly surrounding said intake conduit in which gaseous exhaust from said exhaust conduit is through said apertures, maintained in fluid communication with an interior of said supplemental intake conduit; and (c) a water supply input to said supplemental intake conduit at an end of said conduit opposite to said intake manifold, whereby thermal values from said exhaust gas conduit, imparted to said supplemental intake, will elevate the temperature of said water, firstly evaporating the same and subsequently, hydrolyzing said water prior to its entry into said manifold, this producing a gaseous mixture with fuel value of said exhaust as entering said supplemental intake through said apertures.
Claim 3
Dependent Claim
53 words
The system as recited as recited in claim 1, further comprising: (a) valve means in fluid communication with an output of said water supply and an input to said supplemental intake conduit; and (b) valve means in fluid communication with an output of said supplemental intake conduit and an input to said manifold.
Claim 4
Dependent Claim
40 words
The system as recited in claim 2, in which an elevation of an end of said supplemental intake conduit nearest to said water supply valve defines a higher elevation than an end of said supplemental intake conduit nearest said manifold.
Claim 5
Dependent Claim
21 words
The system as recited in claim 1, further comprising: an auxiliary fuel input to said intake conduit and valve means therewith.
Claim 6
Dependent Claim
14 words
The system as recited in claim 4, in which said auxiliary fuel comprises oil.
