Abstract
Abstract A system for selectively increasing the horsepower of an internal combustion engine having a carburetor for receiving fuel and air for mixing, including an oxygen tank, a conduit arrangement including a valve for selectively supplying oxygen to the engine, a fuel pump, a metering valve in communication with the fuel pump for supplying supplemental fuel to the engine in proportion to the oxygen supplied to the engine, a mixer for mixing the supplemental fuel and oxygen and injecting this mixture into the normal air supplied to the engine, and a signal for indicating if an excessive amount of supplemental fuel and oxygen is being supplied to the engine.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
179 words
A system for obtaining increased horsepower from an internal combustion engine having a fuel and air supply associated therewith comprising first means for supplying oxygen to the engine, second means for supplying supplemental fuel to said engine for combustion by said oxygen, said first means comprising a source of oxygen, first conduit means for effecting communication between said source of oxygen and said engine, valve means in said first conduit means for controlling the flow of oxygen to said engine, said second means comprising second conduit means and a fuel pump for supplying supplemental fuel to said engine, a fuel metering valve in communication with said second conduit means, means responsive to the pressure of oxygen in said first conduit means for controlling the amount of fuel passing through said fuel metering valve, third conduit means in communication with said fuel metering valve for conducting said amount of fuel from said fuel metering valve, and mixing means for mixing said oxygen in said first conduit means and said fuel in said third conduit means for delivery to said engine.
Claim 2
Independent Claim
179 words
A system for obtaining increased horsepower from an internal combustion engine having a fuel and air supply associated therewith comprising first means for supplying oxygen to the engine, second means for supplying supplemental fuel to said engine for combustion by said oxygen, said first means comprising a source of oxygen, first conduit means for effecting communication between said source of oxygen and said engine, valve means in said first conduit means for controlling the flow of oxygen to said engine, said second means comprising second conduit means and a fuel pump for supplying supplemental fuel to said engine, a fuel metering valve in communication with said second conduit means, means responsive to the pressure of oxygen in said first conduit means for controlling the amount of fuel passing through said fuel metering valve, third conduit means in communication with said fuel metering valve for conducting said amount of fuel from said fuel metering valve, and mixing means for mixing said oxygen in said first conduit means and said fuel in said third conduit means for delivery to said engine.
Claim 3
Dependent Claim
60 words
A system as set forth in claim 1 wherein said mixing means comprises an injector having an outlet, fourth conduit means for conducting the normal air supply to said engine, means positioning said outlet in said fourth conduit means for causing the oxygen and fuel emanating from said outlet to be entrained by the air in said fourth conduit means.
Claim 4
Dependent Claim
95 words
A system as set forth in claim 2 wherein said injector comprises a hollow cylindrical member centrally located within said fourth conduit means, fifth conduit means for combining the flow from said first conduit means and said third conduit means and said third conduit means for injecting the mixture of oxygen and fuel tangentially into said hollow cylindrical member, a baffle plate secured proximate the end of said cylindrical member to provide an annular opening at the end thereof and for projecting said mixture transversely to the flow of air in said fourth conduit means.
Claim 5
Dependent Claim
26 words
A system as set forth in claim 2 including means for sensing when excessive amounts of oxygen and fuel are injected into said fourth conduit means.
Claim 6
Dependent Claim
39 words
A system as set forth in claim 1 including a first check valve in said first conduit means and a second check valve in said third conduit means for preventing cross flow between said first and third conduit means.
Claim 7
Independent Claim
106 words
A system for obtaining increased horsepower from an internal combustion engine comprising a primary fuel source, first conduit means in communication with said engine for conducting a normal air supply to said engine, an injector, a supplementary fuel source, second conduit means in communication with said injector for conducting fuel from said supplementary source to said injector; third conduit means in communication with said injector for conducting oxygen to said injector, and means positioning said injector in said first conduit means for causing oxygen and fuel emanating from said injector to be entrained by the air being conducted through said first conduit means to said engine.
Claim 8
Independent Claim
106 words
A system for obtaining increased horsepower from an internal combustion engine comprising a primary fuel source, first conduit means in communication with said engine for conducting a normal air supply to said engine, an injector, a supplementary fuel source, second conduit means in communication with said injector for conducting fuel from said supplementary source to said injector; third conduit means in communication with said injector for conducting oxygen to said injector, and means positioning said injector in said first conduit means for causing oxygen and fuel emanating from said injector to be entrained by the air being conducted through said first conduit means to said engine.
Claim 9
Dependent Claim
84 words
A system for obtaining increased horsepower from an internal combustion engine as set forth in claim 6 wherein said injector comprises a hollow cylindrical member having a closed end and an open end, said injector being centrally and coaxially located within said first conduit means, and a baffle plate secured proximate said open end of said cylindrical member to provide an annular opening at said open end for projecting flow from said injector transversely to the flow of air in said first conduit means.
Claim 10
Dependent Claim
50 words
A system for obtaining increased horsepower from an internal combustion engine as set forth in claim 7 including fourth conduit means for combining the flow from said second conduit means and said third conduit means for injecting a mixture of oxygen and supplemental fuel tangentially into said hollow cylindrical member.
