Method of reducing the vapour pressure of a C3 to C12 hydrocarbon-based motor fuel mixture containing 0.1 to 20 % by volume of ethanol for conventional spark ignition internal combustion engines, wherein, in addition to an ethanol component (b) and a C3 to C12 hydrocarbon component (a), an oxygen-containing additive (c) selected from at least one of the following types of compounds: alcohol other than ethanol, ketone, ether, ester, hydroxy ketone, ketone ester, and a heterocyclic containing oxygen, is used in the fuel mixture in an amount of at least 0.05 by volume of the total fuel, is disclosed. A mixture of fuel grade ethanol (b) and oxygen-containing additive (c) usable in the method of the invention is also disclosed.
L'invention concerne un procédé permettant de réduire la pression de la vapeur dans un mélange de carburant à base d'hydrocarbone C¿3?C¿12? qui contient 0,1 à 20 % d'éthanol par volume, destiné à des moteurs à combustion interne à allumage commandé. Outre le composant éthanol (b) et le composant hydrocarboné C¿3? C¿12? c (a), on utilise un additif à base d'oxygène (c) sélectionné dans le groupe constitué par au moins l'un des types de composés suivants: alcool autre qu'éthanol, cétone, éther, ester, hydroxy cétone, cétone ester, et oxygène hétérocyclique, dans le mélange de carburant selon une quantité d'au moins 0,05 de la totalité du carburant par volume. L'invention concerne également un mélange de carburant à base d'éthanol (b) et d'additif à base d'oxygène (c) utilisable dans ladite invention.
