Title
(EN) ENGINE EXHAUST PARTICULATE FILTER
(FR) FILTRE DE SUBSTANCES PARTICULAIRES CONTENU DANS LES GAZ D"ECHAPPEMENT D"UN MOTEUR
Abstract
(EN)
A filter apparatus for removing particulates from exhaust gases of engines has a housing (10) containing a manifold (13) to receive exhaust gases directly from an inlet opening (12), and the manifold (13) has a series of exhaust openings (23) spaced along its length to discharge exhaust gases outwardly between a pair of filter elements (28, 29). The filter elements (28, 29) trap the particulates and release effectively particulate-free gases to the atmosphere in response to pressure changes in the exhaust gases between the filter elements (28, 29).
(FR)
Dispositif de filtre servant a extraire des substances particulaires des gaz d"echappement d"un moteur, possedant un boitier (10) contenant un collecteur d"echappement (13) servant a recevoir les gaz d"echappement directement d"une ouverture d"admission (12), ce collecteur d"echappement (13) possedant une serie d"ouvertures d"echappement (23) espacees le long de sa longueur pour liberer vers l"exterieur les gaz d"echappement entre une paire d"elements filtres (28, 29). Les elements filtres (28, 29) retiennent les substances particulaires et liberent efficacement dans l"atmosphere des gaz exempts de substances particulaires en reponse a des changements de pression dans les gaz d"echappement entre les elements filtres (28, 29).
