A high-energy-content fuel composition, for controlled-ignition internal combustion engines, contains quadricyclane (tetracyclo-[2.2.1.0-(2,6).0-3,5]-heptane), for which a new synthesis method is proposed. The use of the quadricyclane-containing fuel composition makes it possible a larger amount of energy to be available per each fuel volume unit, and favorably modifies the combustion kinetics in controlled-ignition internal combustion engines.

High-energy-content fuel composition containing quadricyclane

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.
