Title (EN) ARRANGEMENT FOR AGGLOMERATING AND COLLECTING PARTICLES CONTAINED IN EXHAUST GASES OF AN INTERNAL COMBUSTION ENGINE FOR A MOTOR VEHICLE PROVIDED A HIGH-VOLTAGE POWER SUPPLY
(FR) ENSEMBLE D'AGGLOMERATION ET DE COLLECTION DES PARTICULES CONTENUES DANS DES GAZ D'ECHAPPEMENT D'UN MOTEUR A COMBUSTION INTERNE DE VEHICULE AUTOMOBILE POURVU D'UN DISPOSITIF D'ALIMENTATION ELECTRIQUE HAUTE TENSION
Abstract:
(EN) An arrangement for agglomerating and collecting particles contained in exhaust gases of a motor vehicle internal combustion engine comprises at least one electrostatic agglomeration module (10) provided with internal (16) and external (5) electrodes between which an electric field is formed, wherein the external electrode is made of a porous material which lets the exhaust gases and agglomerated particles to pass through while the exhaust gas passage through said material and a module (12) for collecting particles located downstream of said agglomeration module in a direction of the exhaust gas flow. The inventive agglomeration arrangement also comprises a power generating device (22) provided with single step-up transformer for supplying a high DC voltage to the agglomeration and collecting modules.
(FR) L'ensemble d'agglomération et de collection des particules contenues dans des gaz d'échappement d'un moteur à combustion interne de véhicule automobile est pourvu d'au moins un module d'agglomération (10) électrostatique comprenant une électrode interne (16) et une électrode externe (5) entre lesquelles est créé un champ électrique, l'électrode externe étant réalisée en un matériau poreux capable de laisser passer les gaz d'échappement ainsi que des amas de particules agglomérés lors du passage des gaz d'échappement à travers la matière poreuse, et d'un module de collection (12) des amas de particules disposé en aval du module d'agglomération, en considérant le sens de circulation des gaz d'échappement. L'ensemble d'agglomération comprend, en outre, un dispositif de génération (22) électrique muni d'un unique transformateur élévateur de tension apte à permettre une alimentation en haute tension continue du module d'agglomération et du module de collection.
