Abstract: The invention relates to a method for diagnosing the malfunctioning of a device for adding an additive into a fuel for a vehicle comprising an internal combustion engine, said method including: a step of analyzing the fuel in order to determine a variation in the amount of additive in the fuel; a step of comparing the variation in the amount of additive, measured during the previous step, with a theoretical variation in said amount; a step of sending information when the difference between the measured variation and the theoretical variation exceeds a set value. The invention also relates to a system for adding an additive into fuel and for diagnosis for a vehicle comprising an internal combustion engine, which is intended for implementing said method.

Abstract: The present invention relates to compositions containing a detergent composition and an active metal containing compound, where the detergent composition includes a quaternary ammonium salt detergent and optionally an oxygen-containing detergent, and where the active metal containing compound is in the form of a colloidal dispersion, comprising an organic phase, particles of an iron compound in its amorphous form, and at least one amphiphilic agent. These compositions may be used in fuels and provide improved engine performance when such fuels are used, specifically by reducing fuel injector fouling in the engine and/or by improving the regeneration of the engine's particulate exhaust trap.
