Abstract

The V-engine has an exhaust manifold (11) leading to an exhaust turbo-charger. The manifold is contained inside a pressure tight housing formed by an upper part (13), a lower part (18) and seals (22). Exhaust gas enters from the engine through connections (16) and leaves through a connection (17). The manifold is supported at intervals on lugs (12). Additional insulation (19) assists heat retention and provides additional energy in the exhaust gas for input to the turbocharger.

Description

Abgassammelleitung für Brennkraftmaschinen mit mehrerenExhaust manifold for internal combustion engines with several

Zylindern Die Erfindung betrifft eine Kolbenbrennkraftmaschine iit zwei V-förmig angeordneten Zylinderreihen und mit einer ii V liegenden, von eine gasdichten Gehäuse umgebenen Abgassammelleitung iür die Zylinder. Cylinders The invention relates to a piston internal combustion engine iit two V-shaped rows of cylinders and with a ii V lying, of one Gas-tight housing surrounded exhaust manifold for the cylinders.

Eine derartige Abgassammelleitung dient der Zusammenführung und Überleitung der Abgase in den Abgasturbolader der Brennkraftmaschine. Durch das Gehäuse ist ein Schutz gegen Energieverluste durch Abkühlung der Abgase und eine Abdeckung der heißen Abgassammelleitung gegeben. Üblicherweise wird die Abgassammelleitung über Flanschverbindun6en iiir das Abgas mit den Zylinderköpfen der Brennkraitraschine oder itt Zwischenflanschen des gasdichten, die Abgassammelleitungen umgebenden Gehäuses verbunden. Diese Befestigung für die Abgassammelleitun6 ist sehr aufwendig und wegen Platziangel nur umständlich zu montieren, weil dabei die Abgassaiielleitung in We6e ist.Such an exhaust manifold serves to bring together and transfer of the exhaust gases in the exhaust gas turbocharger of the internal combustion engine. Through the housing is a protection against energy losses by cooling the exhaust gases and a cover of the given hot exhaust manifold. Usually the exhaust manifold is over Flange connections for the exhaust gas with the cylinder heads of the combustion engine or itt intermediate flanges of the gas-tight housing surrounding the exhaust manifolds tied together. This attachment for the exhaust manifold is very complex and because of Difficult to assemble because of the lack of space, because the exhaust gas pipe is in We6e is.

Aufgabe der Erfindung ist es deshalb, eine günstigere und einfachere Methode zur Überleitung des Abgases in die Abgassammelleitung und eine einfache Anordnung, Ausbildung und Montageiöglichkeit der Sammelleitung und des sie umgebenden gasdichten Gehäuses aufzuzeigen.The object of the invention is therefore to provide a cheaper and simpler one Method of transferring the exhaust gas into the exhaust manifold and a simple one Arrangement, training and assembly of the manifold and the surrounding one to indicate gas-tight housing.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches gelöst.This task is achieved by the characterizing features of the claim solved.

Durch die Erfindung wird eine einfache, leicht zu iontierende Ausführung für die Abgassammelleitung angegeben, bei der Dichtungen und entsprechende Flansche mit ihren Befestigungen veriteden werden. Das durch die entstehenden Spalten entweichende Abgas baut zwischen Gehäuse und Abgasleitung einen Druck auf, der ein weiteres Entweichen von Abgas sicher verhindert.The invention provides a simple, easy-to-iont design specified for the exhaust manifold, with seals and corresponding flanges be verified with their fortifications. That through the resulting gaps escaping Exhaust gas builds up a pressure between the housing and the exhaust pipe, which further escapes safely prevented from exhaust gas.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below.

Die Zeichnung stellt einen Querschnitt durch eine erfindungsgeiäße Abgassammelleitung dar, lit einer gasdichten Gehäuse und den Abgasanschlüssen von zwei im V zueinander angeordneten Zylindern Eine Abgassammelleitung 11 ist über angeschweißte Beiestigungspunkte 12 ilt einer Gehäuseoberteil 13 verbunden.The drawing represents a cross section through a erfindungsgeiässer Exhaust manifold, lit a gas-tight housing and the exhaust connections from two cylinders arranged in a V to one another. An exhaust manifold 11 is over Welded attachment points 12 are connected to an upper housing part 13.

Mehrere solcher Befestigungspunkte 12 sind aui beiden Seiten der Abgassammelleitung über die Länge verteilt angeordnet. Die mittleren Befestigungspunkte aui jeder Seite sind über Schrauben 14 an der Gehäuseoberteil 13 fixiert. Die übrigen Befestigungspunkte weisen Haltebügel 15 auf, die eine Längenausdehnung der Abgassammelleitung gegenüber den Gehäuseoberteil 13 zulassen Das Gehäuseoberteil weist Abgaskanäle 16 und einen Abgasaustrittsstutzen 17 auf.Several such attachment points 12 are on both sides of the exhaust manifold arranged distributed over the length. The middle attachment points on each side are fixed to the upper housing part 13 by means of screws 14. The remaining attachment points have retaining brackets 15 which have a longitudinal expansion of the exhaust manifold the upper housing part 13 allow the upper housing part has exhaust gas ducts 16 and a Exhaust outlet nozzle 17 on.

Ein Gehäuseunterteil 18 ist einer Wärmeisolierschicht 19 versehen und gasdicht ilt dei Gehäuseoberteil 13 verschraubt.A lower housing part 18 is provided with a heat insulating layer 19 and gas-tight ilt the upper housing part 13 screwed.

Das aus Gehäuseoberteil 13 und Gehäuseunterteil 18 bestehende Gehäuse wird mit der Abgassammelleitung 11 zusammen über Schrauben 20 iit den Zylinderkurbelgehäuse 21 der Brennkraftmaschine verbunden. Dichtungen 22 stellen die Abdichtung zwischen den Zylinderköpfen 23 und der Gehäuseoberteil 13 her.The housing consisting of the upper part 13 and the lower part 18 of the housing is connected to the exhaust manifold 11 together via screws 20 iit the cylinder crankcase 21 connected to the internal combustion engine. Seals 22 provide the seal between the cylinder heads 23 and the upper housing part 13.

Die Abgasübergänge zwischen den Abgaskanälen 16 und der Abgassammelleitung 11 und zwischen der Abgassammelleitung 11 und den Abgasaustrittsstutzen 17 sind berührungslos durch einander gegenüberliegende Öffnungen der Abgaskanäle, der -sammelleitung und der-austrittsstutzen gebildet.The exhaust gas transitions between the exhaust ducts 16 and the exhaust manifold 11 and between the exhaust manifold 11 and the exhaust outlet nozzle 17 are Contactless through opposing openings in the exhaust gas ducts, the manifold and the outlet nozzle is formed.
