Abstract
Abstract A liquid for vaporizing and subsequent introduction, downstream from the carburetor, into the fuel stream of a gasoline-fired internal combustion engine, the liquid comprising water and a concentrate mixed with said water, the concentrate including methanol and nitro-methane. The concentrate may also include a suitable blender or blenders such as acetone and nitro-benzene. The acetone is effective to prevent separation of the nitromethane and methanol.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
15 words
The liquid of claim 1 in which said liquid also includes approximately 18 percent acetone.
Claim 2
Dependent Claim
15 words
The liquid of claim 2 in which the liquid also includes approximately 2 percent nitro-benzene.
Claim 3
Dependent Claim
89 words
A liquid additive for vaporizing and subsequent introduction, downstream from the carburetor along with carbureted gasoline, into the fuel stream of a gasoline-fired internal combustion engine, said liquid comprising water and a concentrate mixed with said water, said concentrate including methanol and nitro-methane as essential ingredients, said water, methanol and nitro-methane being present in said additive in such amounts and proportions as to react among themselves and with the carbureted gasoline to promote combustion of the gasoline and reduce the deleterious contents of the exhaust emissions of said engine.
Claim 4
Dependent Claim
23 words
The liquid of claim 3 in which the methanol and nitro-methane comprise, respectively, approximately 75 percent and 5 percent of the said concentrate.
