Abstract

A fuel composition with a high energy content, for direct-ignition internal combustion engines contains a gasoline from petroleum and an amount of up to 90% by volume, as referred to the same fuel composition, of hydrocarbon "cubane" or of its alkyl-derivatives, to be defined by means of the formula: ##STR1## wherein R'"'"' and R" represent, independently from each other, a hydrogen atom or an alkyl radical containing from 1 to 3 carbon atoms.

Claims

1. Fuel composition for direct-ignition internal combustion engines, with a high energy content, containing a gasoline from petroleum and an amount of up to 90% by volume, as referred to the same fuel composition, of hydrocarbon "cubane" or of its mono-alkyl-or di-alkyl-derivatives, to be defined by means of the formula:

##STR4## wherein R'"'"' and R" represent, independently from each other, a hydrogen atom or an alkyl radical containing from 1 to 3 carbon atoms.

2. Composition according to claim 1, characterized in that it contains from 20 to 60% by volume of cubane or of its mono-alkyl- or di-alkyl-derivatives.
