Patent

CA 2456634

A fuel composition comprises a hydrocarbon fuel, a combination of nitrogen- containing detergents that includes a hydrocarbyl-substituted polyamine and a Mannich reaction product, and optionally a fluidizer. Methods of operating and of controlling deposits in an internal combustion engine involve fueling the engine with the fuel composition which results in unexpectedly effective and efficient control of deposits in the fuel induction system.

Cette invention concerne une composition de carburant contenant d'une part un combustible hydrocarboné et d'autre part une combinaison de détergents à base d'azote comprenant une polyamine à substitution hydrocarbyle ainsi qu'un produit de réaction de Mannich et éventuellement un fondant. Cette invention porte également sur des procédés d'exploitation et de contrôle des dépôts dans un moteur à combustion interne, consistant à alimenter le moteur avec la composition de carburant, et permettant d'obtenir un contrôle incroyablement effectif et efficace des dépôts dans le système d'admission du combustible.
