Abstract
Abstract A method for decreasing hydrocarbons and oxides of nitrogen emanating from the exhaust system of an internal combustion engine involves supplying substantially pure oxygen to the air intake means of the engine. Such pure oxygen may be passed from a tank in which it is stored to the air intake means of the engine. The pure oxygen may be created by storing a chemical compound in a chamber and heating the chamber so that the compound may release the oxygen, or oxygen can be created by electrolytically decomposing water, passing oxygen generated by such decomposition into a storage tank coupled to the air intake means of the engine.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
99 words
A method for decreasing hydrocarbons and oxides of nitrogen emanating from an exhaust system of an internal combustion engine by supplying substantially pure oxygen to said engine, the improvement comprising the steps of: storing a chemical source of oxygen which is at least one compound selected from the group consisting essentially of potassium perruthenate, potassium persulfate, calcium peroxide and potassium pyrophosphate in a chamber; heating said at least one compound to a temperature within the range of about 100° to 360° farenheit so as to release oxygen therefrom; and passing the released oxygen to an intake of said engine.
Claim 2
Independent Claim
99 words
A method for decreasing hydrocarbons and oxides of nitrogen emanating from an exhaust system of an internal combustion engine by supplying substantially pure oxygen to said engine, the improvement comprising the steps of: storing a chemical source of oxygen which is at least one compound selected from the group consisting essentially of potassium perruthenate, potassium persulfate, calcium peroxide and potassium pyrophosphate in a chamber; heating said at least one compound to a temperature within the range of about 100° to 360° farenheit so as to release oxygen therefrom; and passing the released oxygen to an intake of said engine.
Claim 3
Dependent Claim
20 words
The method of claim 1, wherein said chemical source of oxygen is limited to substantially a compound of potassium perruthenate.
Claim 4
Independent Claim
20 words
The method of claims 1, wherein said chemical source of oxygen is limited to substantially a compound of potassium persulfate.
Claim 5
Dependent Claim
20 words
The method of claim 1, wherein said chemical source of oxygen is limited to substantially a compound of calcium peroxide.
Claim 6
Dependent Claim
20 words
The method of claim 1, wherein said chemical source of oxygen is limited to substantially a compound of potassium pyrophosphate.
