摘要:
A fuel additive is formed from dispersions including an organic phase, at least one amphiphlic agent and solid objects based on particles of an iron compound in the crystallized form with a small size, as a fuel additive. The particles have an average size DDRX of less than or equal to 7 nm measured by X-ray diffraction, and at least 80% by number of the particles have a size DMET of less than or equal to 7 nm measured by transmission electron microscopy.

摘要:
Compositions that include a detergent composition and an active metal compound are described wherein the detergent composition includes a quaternary ammonium salt detergent and optionally an oxygen-containing detergent, and wherein the active metal 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 can be used in fuels to provide improved engine performance by, for example, reducing fuel injector fouling in the engine and/or by improving the regeneration of the engine's particulate exhaust trap.
摘要:
The invention relates to a process for operating an internal combustion engine of a vehicle equipped with an exhaust system comprising a catalysed particulate filter in which the engine is supplied with a fuel containing a catalyst for regenerating the particulate filter. The process is characterized in that the concentration of catalyst in the fuel varies discontinuously.
