Abstract

Abstract Translated from French Procédé de régénération de filtres à particules, notamment pour moteurs Diesel. On injecte périodiquement en amont du filtre colmaté un liquide organique tel que Cx Hy Oz, du type éthanol ou méthanol possédant une température de vaporation basse, le cas échéant additionné d'eau, ledit liquide organique, après avoir été préchauffé et craqué de façon à donner naissance à un mélange très inflammable essentiellement constitué d'hydrogène et d'oxyde de carbone, est introduit sur le trajet des gaz d'échappement incidents. Application aux moteurs Diesel. Method for regenerating particulate filters, in particular for diesel engines. An organic liquid such as Cx Hy Oz, of the ethanol or methanol type having a low vaporization temperature, optionally added with water, is periodically injected upstream of the clogged filter, said organic liquid, after having been preheated and cracked so as to giving rise to a highly flammable mixture essentially consisting of hydrogen and carbon monoxide, is introduced into the path of the incident exhaust gases. Application to Diesel engines.
