(DE) RUSSPARTIKELFILTER MIT KATALYTISCH BESCHICHTETEM HEIZELEMENT
(EN) SOOT PARTICLE FILTER WITH CATALYST-COATED HEATING ELEMENT
(FR) FILTRE A PARTICULES DE SUIE ASSURANT UNE COMBUSTION DE SUIE A COMMANDE VARIABLE
Abstract
(DE)
Rußpartikelfilter für Dieselmotoren und Ölheizungen bestehend aus mindestens einem Filtergehäuse (3) , mindestens einem Filterelement (13, 14) und mindestens einem Heizelement (8) , das durch Öffnungen (6, 7) in das Filtergehäuse ragt, wobei das Heizelement aus zug und druckfesten Heizspirale (24 besteht, die mit katalytisch beschichteten Kerakschnüren umhüllt sind.
(EN)
The invention relates to a soot particle filter for diesel engines and oil heaters, comprising at least one filter housing (3) at least one filter element (13)(14) and at lest one heating element (8) extending through openings (6, 7) in the filter housing (3) the heating elements being made from tensile and pressure resistant heating spirals (24) enclosed by ceramic ties.
(FR)
L'invention concerne un filtre à particules de suie assurant une combustion de suie à commande variable et présentant une action catalytique, ce filtre étant conçu pour des moteurs diesels et des chauffages au fioul. Le filtre à particules de suie selon l'invention comprend au moins un logement de filtre (3), et un élément de filtrage (13, 14). Cette invention est caractérisée en ce que la partie catalytique (13) est assemblée, dans le logement (3), avec des ficelles céramiques (23) qui comportent des spirales chauffantes (24) constituées de matériaux résistant à la traction et à la pression, de manière à former un faisceau, et en ce qu'une rotation du faisceau de ficelles céramiques permet ensuite d'obtenir une forme spiralée.
