Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 117 words
A gasoline additive composition designed to be added to the fuel tank of an automobile, said composition comprising the following components: a) from about 0.1 to about 20% by weight of an organic peroxide; b) from about 0.5 to about 20% by weight of a gasoline detergent selected from amines, diamines, fatty imidazolines, polymeric amines and combinations thereof with carboxylic acids; c) from about 99.4 to about 60% by weight of a hydrocarbon solvent; said composition intended to be used in unleaded and leaded gasolines at a level of from about 0.01% to about 5% in order to improve the efficiency of combustion within the engine, thereby boosting engine power, improving fuel economy and reducing tailpipe emissions.
Claim 2
Dependent Claim 117 words
A gasoline additive composition designed to be added to the fuel tank of an automobile, said composition comprising the following components: a) from about 0.1 to about 20% by weight of an organic peroxide; b) from about 0.5 to about 20% by weight of a gasoline detergent selected from amines, diamines, fatty imidazolines, polymeric amines and combinations thereof with carboxylic acids; c) from about 99.4 to about 60% by weight of a hydrocarbon solvent; said composition intended to be used in unleaded and leaded gasolines at a level of from about 0.01% to about 5% in order to improve the efficiency of combustion within the engine, thereby boosting engine power, improving fuel economy and reducing tailpipe emissions.
Claim 3
Dependent Claim 16 words
The gasoline additive composition of Claim 1 wherein the organic peroxide component is di-tertiary butyl peroxide.
Claim 4
Dependent Claim 22 words
The gasoline additive composition of Claim 2 wherein the gasoline detergent is a fatty imidazoline in combination with a dimethyl alkanoic acid.
Claim 5
Dependent Claim 44 words
The gasoline additive composition of Claim 3 wherein the di-tertiary butyl peroxide is present at a level of about 1 to 10% and the fatty imidazoline and dimethyl alkanoic acid gasoline detergent combination is present at a level of from about 2 to 10%.
Claim 6
Dependent Claim 29 words
An improved fuel composition for a gasoline internal combustion engine comprising gasoline in admixture with from about 0.25 to about 1.5% of the gasoline additive composition of Claim 1.
