Description
Die Erfindung betrifft luftspaltisolierte Abgaskrümmer für Brennkraftmaschinen gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to air gap insulated exhaust manifolds for internal combustion engines according to the preamble of claim 1.
Abgaskrümmer haben
die Aufgabe, die aus den Zylinderauslässen des Verbrennungsmotors austretenden
heißen
Abgase zu sammeln und an die nachfolgenden Abgaskomponenten wie
Katalysator, Schalldämpfer
usw. weiterzuleiten. Dabei sind sie hohen thermischen Belastungen
durch die heißen
Abgase ausgesetzt. Um die dadurch bedingte hohe Wärmeabgabe
an die Umgebung zu reduzieren, können
die Abgaskrümmer
zunächst
mit einer Wasserkühlung
versehen werden. Ein Beispiel zeigt die

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Abgaskrümmer der eingangs genannten Art anzugeben, der aus nur wenigen Einzelteilen besteht und sich einfach und überwiegend automatisiert zusammenbauen lässt.Of the present invention is based on the object, an exhaust manifold of the to specify the type mentioned above, from only a few items exists and is simple and prevalent automated assembly.
Diese Aufgabe wird gelöst durch einen Abgaskrümmer mit den Merkmalen des Anspruchs 1.These Task is solved through an exhaust manifold with the features of claim 1.
Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.advantageous Further developments emerge from the subclaims.
Ein erster wesentlicher Vorteil des erfindungsgemäßen Abgaskrümmers ist, dass er aus lediglich fünf Einzelteilen besteht. Ein weiterer Vorteil ist, dass sowohl die Innenschale als auch die Außenschale in sich geschlossene Gebilde darstellen, die dadurch eine hohe Stabilität besitzen. Des weiteren lassen sich die Schweißnähte zwischen Unter- und Oberteil von Innen- und Außenschale so positionieren, dass keine Gefahr besteht, dass Schweißspritzer in den abgasführenden Teilen verbleiben. Die Montagegrundfläche des Abgaskrümmers am Motorblock ist minimal. Freigänge für die Befestigungsschrauben lassen sich in Innen- und Außenschale problemlos einformen. Insgesamt ist die Montage des erfindungsgemäßen Abgaskrümmers am Motorblock identisch mit der derzeitigen Vorgehensweise.A first significant advantage of the exhaust manifold according to the invention is that it consists of only five parts. Another advantage is that both the inner shell and the outer shell are self-contained structures, which thus have a high stability. Furthermore, the welds between the lower and upper part of the inner and outer shell can be positioned so that there is no danger that welding fuel zer remain in the exhaust-carrying parts. The mounting surface of the exhaust manifold on the engine block is minimal. Clearances for the fixing screws can easily be formed in the inner and outer shell. Overall, the assembly of the exhaust manifold according to the invention on the engine block is identical to the current procedure.
Die Innenschale besitzt eine definierte Position, der Ausgleich der thermischen Ausdehnungsdifferenzen ist in vollem Umfang gewährleistet.The Inner shell has a defined position, balancing the thermal expansion differences is fully guaranteed.
Anhand der Zeichnung soll die Erfindung in Form eines Ausführungsbeispiels näher erläutert werden.
