Abstract

1416844 Fuel J MICHAELS 8 Feb 1974 05942/74 Heading C5G A fuel composition for internal combustion engines comprises a homogeneous blend of (A) 5-95 vol. per cent of gasoline (defined) and (B) 95-5 vol. per cent of a blend comprising (a) 10-90 vol. per cent of a nitroalkane having 1 or 2 nitro groups, and containing up to 4 C atoms, and mixtures thereof and (b) 90-10 vol. per cent of at least 1 normally liquid ester lubricant having a viscosity of at least 1 centistoke selected from (i) esters of lineary primary alcohols and linear dicarboxylic acids (ii) esters of branched chain primary alcohols and linear dicarboxylic acids (iii) esters of branched or linear chain monocarboxylic acids and linear or branched chain dihydric alcohols and/or polyalkylene glycols (iv) esters of linear or branched chain primary alcohols and branched chain dicarboxylic acids (v) esters of alkane polyols and monocarboxylic acids having the formula below where R 3 to R 6 , which may the same or different, are selected from (a) C 1 -C 10 alkyl, straight chain or branched and (b) -C 5 H 25 OOCR 7 where S is 1 to 4 and R 7 is C 4 -C 12 alkyl, straight chain or branched provided that no more than 2 of R 3 -R 6 groups are alkyl groups and (vi) mixed complex esters of straight chain or branched primary alcohols, straight chain or branched mono- and dicarboxylic acids and polyalkylene glycols. The ester lubricant does not exceed 25 vol. per cent of the fuel composition. The term "gasoline" includes natural gasoline and straight, unblended aliphatic hydrocarbons having from 5 to 12 carbon atoms. The fuel may be used for reciprocating piston engines, turbine engines and glow engines.
