Title (EN) EXHAUST GAS RECIRCULATION FILTRATION SYSTEM
(FR) SYSTEME FILTRANT DE RECIRCULATION DES GAZ D'ECHAPPEMENT
Abstract:
(EN) A filtration system (10) adapted to prevent diesel soot carried with recirculated exhaust gas from being recirculated through internal combustion engine. The filtration system provides continuous elimination of soot, thus reducing its negative impact on engine life, lubrication oil quality, and on components in the exhaust gas recirculation system. The filtration system comprises a non-thermal plasma generator (34) that periodically, or continuously, oxidizes carbon deposited, or trapped, within a carbon filter (32) disposed downstream of the non-thermal plasma generator.
(FR) L'invention concerne un système filtrant (10) destiné à empêcher la suie de diésel transportée avec les gaz d'échappement remis en circulation de recirculer dans un moteur à combustion interne. Le système filtrant élimine la suie de façon continue, réduisant ainsi son impact négatif sur la durée de vie du moteur, sur la qualité de l'huile de graissage, et sur les composants du système de recirculation des gaz d'échappement. Le système filtrant comprend un générateur (34) de plasma non thermique qui, de façon périodique ou continue, oxyde le carbone déposé ou coincé dans un filtre (32) de carbone situé en aval du générateur de plasma non thermique.
