Abstract

L'invention porte sur un procédé de décrassage ou de prévention d'encrassement d'au moins un injecteur de carburant dans un véhicule automobile, l'injecteur étant relié à un circuit d'alimentation en carburant partant du réservoir de carburant, avec mesure ou estimation de la quantité de carburant injectée dans le moteur par l'injecteur, quand cette quantité est jugée suffisante, diagnostic d'un non encrassement de l'injecteur et ajout en continu d'une première quantité de n-heptane (lhep1) dans le carburant, cette première quantité (lhep1) étant suffisante pour assurer un traitement préventif (SP) d'un encrassement de l'injecteur, quand cette quantité de carburant injectée est jugée insuffisante, diagnostic d'un encrassement de l'injecteur et ajout d'une série de secondes quantités de n-heptane (lhep2) équivalentes dans le carburant par intermittence, ces secondes quantités (lhep2) étant suffisantes pour effectuer un traitement curatif (SC), chaque seconde quantité (lhep2) étant plus grande que la première quantité (Ihep1).The invention relates to a method of slagging or preventing clogging of at least one fuel injector in a motor vehicle, the injector being connected to a fuel supply circuit starting from the fuel tank, with measurement or estimation of the quantity of fuel injected into the engine by the injector, when this quantity is considered sufficient, diagnosis of a non-fouling of the injector and continuous addition of a first quantity of n-heptane (lhep1) in the fuel, this first quantity (lhep1) being sufficient to ensure a preventive treatment (SP) of a clogging of the injector, when this quantity of injected fuel is considered insufficient, diagnosis of a clogging of the injector and addition of a series of second quantities of n-heptane (lhep2) equivalent in the fuel intermittently, these second quantities (lhep2) being sufficient to effect a curative treatment (SC), each second quantity (lhep2) being more greater than the first quantity (Ihep1).
