Nombre d'une échelle conventionnelle exprimant la résistance à la détonation des carburants utilisés dans les moteurs à allumage commandé. (Cette caractéristique essentielle détermine les qualités de combustion d'un carburant et ses conditions optimales d'utilisation.) [...] Les carburants de référence sont deux hydrocarbures purs choisis pour leur comportement extrême au point de vue l'heptane normal, très détonant et affecté conventionnellement d'une valeur nulle et un isoctane, le trémethyl-1,2,4 pentane, réfractaire à la détonation et affecté d'un indice d'octane égal à 100. 6, record 1, French, - taux%20d%26rsquo%3Boctane
