Abstract (en)

[origin: WO2007085561A1] The invention relates to a method of improving an engine equipped with an exhaust line fitted with a particulate filter, in which the particulates contained in the exhaust gas are trapped on said filter, and the trapped particulates are periodically burnt off, which method is characterized in that, for the purpose of catalysing the combustion of said particles, a composition resulting from mixing a lubricating oil with a colloidal dispersion is used as engine-lubricating composition, which dispersion comprises particles of a compound of at least one rare earth and an amphiphilic agent.
