(FR) BRIDE DE COLLECTEUR D'ECHAPPEMENT POUR UN MOTEUR A COMBUSTION INTERNE
Abstract
(DE)
Es wird ein Abgaskrümmerflansch für eine Verbrennungskraftmaschine vorgeschlagen, der wenigstens ein Basisteil (24) mit mindestens einer Ausnehmung (4) für einen Abgasstutzen (26) und mindestens eine Öffnung (12, 13) zu einem Zylinderzugang am Motorblock der Kraftmaschine sowie Zuführungsmittel für Sekundärluft und/oder rückgeführtes Abgas umfasst, wobei die Zuführungsmittel mit der Öffnung (12, 13) zu dem Zylinderzugang in Verbindung stehen. Erfindungsgemäss weisen die Zuführungsmittel einen unmittelbar auf dem wenigstens einen Basisteil (24) angeordneten Gaskanal (9) auf, der sich über nur einen Teilbereich des Basisteils (24) erstreckt, und aus zwei gasdicht miteinander verbundenen Schalenelementen (10, 11) gebildet ist.
(EN)
Disclosed is an exhaust gas collector flange for an internal combustion engine, comprising at least one base part (24) with at least one recess (4) for an exhaust muff (26) and at least one opening (12, 13) towards a cylinder access on the engine block of the engine, in addition to supply means for secondary air and/or recycled exhaust gas, whereby the supply means are in contact with the opening (12, 13) to the cylinder access. According to the invention, the supply means consist of a gas duct (9) that is arranged directly on the at least one base part (24), whereby said gas duct extends over only one partial area of the base part (24) and is formed from two gastight interconnected shell elements (10, 11).
(FR)
L'invention concerne une bride de collecteur d'échappement pour un moteur à combustion interne, comprenant au moins une base (24) qui présente au moins un évidement (4) pour une tubulure d'échappement (26) et au moins une ouverture (12, 13) vers un accès aux cylindres du bloc moteur, ainsi que des éléments d'acheminement pour l'air secondaire et/ou les gaz d'échappement recyclés. Ces éléments d'acheminement communiquent avec l'ouverture (12, 13) vers l'accès aux cylindres. Selon l'invention, les éléments d'acheminement présentent un canal de gaz (9) qui est placé directement sur la ou les bases (24), s'étend seulement sur une zone partielle de la ou des bases (24) et est formé à partir de deux coques (10, 11) communiquant entre elles de manière étanche aux gaz.
