Abstract A fuel composition for a spark-ignition internal combustion engine comprises an additive having a chemical structure comprising a 6-membered aromatic ring sharing two adjacent aromatic carbon atoms with a 6- or 7-membered saturated heterocyclic ring, the 6- or 7-membered saturated heterocyclic ring comprising a nitrogen atom directly bonded to one of the shared carbon atoms to form a secondary amine and an atom selected from oxygen or nitrogen directly bonded to the other shared carbon atom, the remaining atoms in the 6- or 7-membered heterocyclic ring being carbon. The additive increases the octane number of the fuel, thereby improving the auto-ignition characteristics of the fuel. La présente invention concerne une composition de carburant pour un moteur à combustion interne à allumage par étincelle comprenant un additif ayant une structure chimique comprenant un cycle aromatique à 6 chaînons partageant deux atomes de carbone aromatiques adjacents avec un cycle hétérocyclique saturé à 6 ou 7 chaînons, le cycle hétérocyclique saturé à 6 ou 7 chaînons comprenant un atome d'azote directement lié à l'un des atomes de carbone partagés pour former une amine secondaire et un atome sélectionné parmi l'oxygène ou l'azote lié directement à l'autre atome de carbone partagé, les atomes restants du cycle hétérocyclique à 6 ou 7 chaînons étant des atomes de carbone. L'additif augmente l'indice d'octane du carburant, ce qui permet d'améliorer les caractéristiques d'auto-allumage du carburant.
