Abstract
Eine Abgasnachbehandlungsanordnung (10) für einen Verbrennungsmotor umfasst ein hohles Gehäuse (12), das mindestens eine Abgasnachbehandlungseinheit (16, 18) enthält. Durch das hohle Gehäuse (12) wird eine Düse (24) zum Wegleiten von Abgasen von der mindestens einen Abgasnachbehandlungseinheit (16, 18) gebildet. Eine hohle zylindrische Abschirmung (30) umgibt das hohle Gehäuse (12) und ist davon beabstandet. Eine Venturi-Einheit (50) empfängt Abgase von der Düse (24) und empfängt Außenluft. Die Venturi-Einheit (50) wirkt dahingehend, Außenluft über eine Außenseite der hohlen zylindrischen Abschirmung (30) zu ziehen und die Außenluft mit durch die mindestens eine Abgasnachbehandlungseinheit (16, 18) strömenden Abgasen zu vermischen.An exhaust gas aftertreatment arrangement (10) for an internal combustion engine comprises a hollow housing (12) which contains at least one exhaust gas aftertreatment unit (16, 18). The hollow housing (12) forms a nozzle (24) for guiding exhaust gases away from the at least one exhaust gas aftertreatment unit (16, 18). A hollow cylindrical shield (30) surrounds the hollow housing (12) and is spaced therefrom. A venturi unit (50) receives exhaust gases from the nozzle (24) and receives outside air. The venturi unit (50) acts to draw outside air over an outside of the hollow cylindrical shield (30) and to mix the outside air with the exhaust gases flowing through the at least one exhaust gas aftertreatment unit (16, 18).
Description
Die vorliegende Erfindung betrifft eine Abgasnachbehandlungsanordnung für einen Verbrennungsmotor.The present invention relates to an exhaust aftertreatment device for an internal combustion engine.
Eine Abgasbehandlungskomponenteanordnung für ein geländegängiges Fahrzeug, wie zum Beispiel einen Ackerschlepper, wird in der
Es wird ein Regenerationsprozess mit Abgasnachbehandlungsvorrichtungen verwendet, bei dem Ruß und Partikel verbrannt werden, und Temperaturen innerhalb der Vorrichtungen können 630 Grad Celsius erreichen. Darüber hinaus können einige der Nachbehandlungsvorrichtungshauttemperaturen in bestimmten Bereichen höhere Temperaturen als erwünscht erreichen. Bei Fahrzeugbetrieb und insbesondere während Regenerierung solcher Nachbehandlungsvorrichtungen ist es erwünscht, die Erwärmung solch einer Abgasnachbehandlungsvorrichtung zu begrenzen.A regeneration process is used with exhaust aftertreatment devices in which soot and particulates are burned and temperatures within the devices can reach 630 degrees Celsius. In addition, some of the aftertreatment skin temperatures in certain areas may reach higher temperatures than desired. In vehicle operation, and particularly during regeneration of such aftertreatment devices, it is desirable to limit the heating of such an exhaust aftertreatment device.
Demgemäß besteht eine Aufgabe der vorliegenden Erfindung in der Bereitstellung einer Abgasnachbehandlungsanordnung, die Abgasluft, die dort hindurch strömt, abkühlt.Accordingly, it is an object of the present invention to provide an exhaust aftertreatment assembly that cools exhaust air flowing therethrough.
Eine weitere Aufgabe der Erfindung besteht in der Bereitstellung einer Abgasnachbehandlungsanordnung, die die Abgasnachbehandlungskomponenten abkühlt.Another object of the invention is to provide an exhaust aftertreatment assembly that cools the exhaust aftertreatment components.
Diese und andere Aufgaben werden durch die vorliegende Erfindung gelöst, wobei eine Abgasnachbehandlungsanordnung für einen Verbrennungsmotor ein hohles Gehäuse umfasst, das mindestens eine Abgasnachbehandlungseinheit enthält. Durch das hohle Gehäuse wird eine Düse zum Wegleiten von Abgasen von der mindestens einen Abgasnachbehandlungseinheit gebildet. Eine hohle zylindrische Abschirmung umgibt das hohle Gehäuse und ist davon beabstandet. Eine Venturi-Einheit empfängt Abgase von der Düse und empfängt Außenluft. Die Venturi-Einheit wirkt dahingehend, Außenluft über eine Außenseite der hohlen zylindrischen Abschirmung zu ziehen und die Außenluft mit durch die mindestens eine Abgasnachbehandlungseinheit strömenden Abgasen zu vermischen.These and other objects are achieved by the present invention wherein an exhaust aftertreatment assembly for an internal combustion engine comprises a hollow housing containing at least one exhaust aftertreatment unit. Through the hollow housing, a nozzle is formed for the passage of exhaust gases from the at least one exhaust aftertreatment unit. A hollow cylindrical shield surrounds and is spaced from the hollow housing. A venturi unit receives exhaust gases from the nozzle and receives outside air. The venturi unit functions to draw outside air over an outside of the hollow cylindrical shield and to mix the outside air with exhaust gases flowing through the at least one exhaust aftertreatment unit.
