Abstract:
Disclosed is a fuel composition comprising a hydrocarbon boiling in the gasoline or diesel range and from about 30 to about 5,000 parts per million of a fuel soluble alkylphenyl poly(oxyalkylene) aminocarbamate having at least one basic nitrogen and an average molecular weight of about 800 to 6,000 and wherein the alkyl group contains at least 40 carbon atoms. The instant invention is based on the discovery that use of the unique hydrocarbyl gorup, i.e., an alkylphenyl group wherein the alkyl group contains at least 40 carbon atoms provides for improved lubricating oil compatibility.

Abstract:
A family of liquid hydrocarbon motor fuel additives known as polynitro alkyls having the general formula R.sub.1 --C(NO.sub.2).sub.2 --R.sub.2 have been found to enhance the overall combustion characteristics of motor fuels by increasing combustion efficiency and reducing undesirable combustion by-products.
Abstract:
A fuel composition for gasoline engines which keeps combustion chambers clean, does not contribute to octane requirement increase and even serves to decrease the octane requirements of an engine which has undergone octane requirement increase while operating on other fuel compositions. The fuel composition comprises a major amount of gasoline and at least 0.4 weight percent of a hydrocarbyl poly(oxyalkylene) aminocarbamate.
