Abstract

Cette invention se rapporte à un carburant liquide peu polluant, qui comprend 10 à 50 % en volume d'au moins deux alcools monohydriques aliphatiques, 40 à 60 % en volume d'au moins un hydrocarbure (un)saturé, et 10 à 30 % en volume d'au moins un éther. On produit ce carburant en mélangeant ces ingrédients dans leur ordre de polarité. Ce carburant ne nécessite aucune modification de la structure/matériau des moteurs à essence à combustion interne existants. Il est utilisé seul ou mélangé à de l'essence, et on obtient grâce à lui un rendement ou une puissance qui sont égaux ou supérieurs à ceux réalisables avec de l'essence, et les gaz d'échappement produits par un moteur ainsi alimenté ont une teneur considérablement réduite en monoxyde de carbone (CO) et en hydrocarbures (HC).
