Abstract

The arrangement places a water-cooled cooler (6) for recirculated exhaust gas, and a water-oil heat exchanger (5) for cooling the engine oil, between the cylinder banks (2,3), below the induction system air cleaner (7). The exhaust gas- and engine oil coolers are coupled to the engine coolant circuit. A cross-pipe (17) feeds exhaust gas from the exhaust manifolds (13,15), upstream of the turbochargers (10,12) to the cooler, and at the cooler can be straight-through, or can have a blanking plate to keep separate the exhaust gases from each bank. The cross-pipe can be free-standing (17a), or can be, in part, integral (17b) with the cylinder heads.

Brennkraftmaschinen in V-Bauart mit jeweils vier Zylindern pro Zylinderreihe und mit Abgasrückführung sowie mit einem Luftzu­ führungsgehäuse und Wärmetauscher, darüber hinaus mit zwei par­ allel wirkenden Abgasturboladern sind hinreichend bekannt.V-type internal combustion engines with four cylinders each Row of cylinders and with exhaust gas recirculation and with an air supply guide housing and heat exchanger, also with two par Allel-acting exhaust gas turbochargers are well known.

Der Erfindung liegt die Aufgabe zugrunde, an einer mehrzylin­ drigen Brennkraftmaschine eine optimale Bauraumausnutzung ver­ schiedener Komponenten, wie Wärmetauscher und Luftzuführungsge­ häuse, sowie stromauf der Abgasturbolader druckausgleichende Maßnahmen zwischen den beiden Zylinderreihen sowie thermisch unkritische Abgasrückführungen zu schaffen.The invention is based on a Mehrzylin the task drigen internal combustion engine an optimal use of space various components, such as heat exchangers and air supply devices housing, and upstream of the exhaust gas turbocharger pressure equalizing Measures between the two rows of cylinders as well as thermally to create uncritical exhaust gas recirculation.

Zur Lösung der Aufgabe dienen die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale.To solve the problem serve in the characterizing part of the Claim 1 specified features.

In den Unteransprüchen sind noch vorteilhafte Weiterbildungen der Erfindung angegeben. Advantageous further developments are in the subclaims specified the invention.  

Durch die zusätzliche Anordnung eines Wärmetauschers als Ölküh­ ler und eines weiteren Wärmetauschers als Abgasrückführungsküh­ ler im V-Raum der Brennkraftmaschine ergibt sich eine vorteil­ hafte Bauraumausnutzung, die insbesondere durch die schichtwei­ se Positionierung der verschiedenen Bauteile sehr platzsparend ist.The additional arrangement of a heat exchanger as an oil cooler ler and another heat exchanger as exhaust gas recirculation cooler There is an advantage in the V-space of the internal combustion engine use of space, which is particularly due to the layered The positioning of the various components is very space-saving is.

Außerdem hat die zentrale Position des Abgasrückführungskühlers zwischen den beiden Zylinderreihen den Vorteil, daß die Abgas­ rückführung aus der Abgasleitung beider Zylinderreihen glei­ chermaßen erfolgen kann.It also has the central position of the exhaust gas recirculation cooler between the two rows of cylinders the advantage that the exhaust gas return from the exhaust pipe of both cylinder banks can be done.

Die Wärmetauscher, nämlich der Abgasrückführungskühler und ein Ölkühler im V-Raum der Brennkraftmaschine, können aufgrund der günstigen Anordnung auf einfachste Weise am Wasserkreislauf der Brennkraftmaschine angeschlossen sein.The heat exchanger, namely the exhaust gas recirculation cooler and a Oil coolers in the V-space of the internal combustion engine can, due to the favorable arrangement in the simplest way on the water cycle Internal combustion engine to be connected.

Zur Verbindung des Abgasrückführungskühlers mit der jeweiligen Abgasleitung kann eine Querleitung vorgesehen sein, die an dem Abgasrückführungskühler angeflanscht ist, welcher mit Kühlkanä­ len versehen ist, die für rückgeführte Abgase als Dämpfungs­ strecke wirken.To connect the exhaust gas recirculation cooler to the respective one Exhaust line, a cross line can be provided on the Flue gas recirculation cooler is flanged, which with cooling channel len is provided for the recirculated exhaust gases as damping stretch work.

Je nach Bedarfsfall kann die Querleitung als durchgehend offene Verbindungsleitung ausgebildet sein, durch die neben einem Druckausgleich auch ein Druckwellen- bzw. Impuls- und Masseaus­ tausch von der einen Zylinderbank zur anderen Zylinderbank stattfinden kann.Depending on the need, the cross line can be open throughout Connection line to be formed, through which in addition to a Pressure equalization also includes a pressure wave or pulse and mass balance exchange from one cylinder bank to the other cylinder bank can take place.

Die Querleitung kann aber auch mit einer Trennwand versehen sein, durch die der rückgeführte Abgasstrom von der einen Zy­ linderreihe und der rückgeführte Abgasstrom von der anderen Zy­ linderreihe in getrennter Weise in den Abgasrückführungskühler einströmen. The cross line can also be provided with a partition be, through which the recirculated exhaust gas flow from one Zy row of linders and the recirculated exhaust gas flow from the other Zy Row of linders in a separate manner in the exhaust gas recirculation cooler flow in.  

Bei dieser Ausführung findet auch ein Druckausgleich statt, je­ doch wird hier ein Impulsaustausch aufgrund der zunächst zu durchlaufenden Kühlkanäle unterbunden. Die Zusammenführung der beiden Abgasströme erfolgt also nach einer Dämpfungs- bzw. Be­ ruhigungsstrecke, die in einen Mischraum im Abgasrückführungs­ gehäuse mündet.In this version, there is also pressure equalization, depending however, here an impulse exchange is initially due to the continuous cooling channels prevented. The merger of the Both exhaust gas flows thus take place after a damping or loading calming section leading into a mixing room in the exhaust gas recirculation system housing opens.

Die Dämpfungsstrecke kann durch geeignete Strömungswiderstände in Form von in dem Abgasrückführungskühler eingebrachten Kühl­ kanälen oder Bögen als längere Gaslaufstrecken ausgebildet sein. Der Masseaustausch setzt somit zeitlich verzögert ein.The damping section can be adjusted by suitable flow resistances in the form of cooling introduced in the exhaust gas recirculation cooler channels or arches formed as longer gas routes be. The mass exchange is therefore delayed.

Die Querleitung kann als freiliegende Verbindungsleitung ausge­ bildet sein, die vor der Stirnseite der Zylinderreihen ver­ läuft. Die Querleitung kann im Falle enger Platzverhältnisse im Motorraum durch die Zylinderreihen hindurch verlaufen.The cross line can be made as an exposed connecting line forms be, the ver in front of the front of the rows of cylinders running. The cross line can be used in tight spaces Run the engine compartment through the rows of cylinders.

Eine zu dem Abgasturbolader 10 führende Abgasleitung 13 ist mit einem Anschluß 14 versehen, ebenso wie eine zu dem Abgasturbo­ lader 12 führende Abgasleitung 15, deren Anschluß mit 16 be­ zeichnet ist. Beide stromauf des jeweiligen Abgasturboladers 10, 12 angeordneten Anschlüsse 14, 16 sind für eine sich über beide Zylinderreihen 2, 3 erstreckende Querleitung 17 bestimmt.A leading to the exhaust gas turbocharger 10 exhaust pipe 13 is provided with a connection 14 , as is a charger to the exhaust gas turbo 12 leading exhaust pipe 15 , the connection of which is marked with 16 be. Both connections 14 , 16 arranged upstream of the respective exhaust gas turbocharger 10 , 12 are intended for a transverse line 17 extending over both rows of cylinders 2 , 3 .

Gemäß Fig. 2 ist die Querleitung 17 an dem langgestreckt ausge­ bildeten Abgasrückführungskühler 6 angeflanscht, und zwar im stirnseitigen Bereich in der Mitte dieses Abgasrückführungsküh­ lers 6.Referring to FIG. 2, the transverse line is flange 17 on the elongated been formed EGR cooler 6, namely in the end region in the middle of this Abgasrückführungsküh coupler 6.

Die Querleitung 17 kann als freiliegende Verbindungsleitung 17a zwischen den Anschlüssen 14, 16 ausgebildet sein, sie kann aber sowohl in der linken Zylinderreihe 2 als auch in der rechten Zylinderreihe 3 integiert sein bzw. die Zylinderreihen 2, 3 durchsetzen. In Fig. 1 sind beide Ausführungsbeispiele hälfig gezeigt, nämlich auf der linken Seite der Brennkraftmaschine 1 die freiliegende Verbindungsleitung 17a und auf der rechten Seite der Brennkraftmaschine 1 die die Zylinderreihe 3 durch­ setzende Verbindungsleitung 17b. Diese Verbindungsleitung 17b ist an dem Zylinderkopf in Höhe des Auslaßkanales im nahen Be­ reich der Stirnseite der Zylinderreihe 3 angeflanscht.The transverse line 17 can be designed as an exposed connecting line 17 a between the connections 14 , 16 , but it can be integrated both in the left row 2 of cylinders and in the right row 3 of cylinders or pass through the rows of cylinders 2 , 3 .

Die Querleitung 17 kann durch eine Trennwand 18 in zwei vonein­ ander getrennte Leitungsabschnitte aufgeteilt sein, durch die eine Trennung der von beiden Abgasleitungen 19, 20 der jeweili­ gen Zylinderreihen 2, 3 rückgeführten Abgasströme erfolgt. Die getrennten Abgasströme durchlaufen eine Dämpfungsstrecke bzw. Beruhigungsstrecke in dem Abgasrückführungskühler 6, die durch geeignete Strömungswiderstände in Form von in dem Abgasrückfüh­ rungskühler eingebrachten und in Längsrichtung verlaufenden Kühlkanälen 21 oder bogenförmigen Kühlleitungen als längere Gaslaufstrecke ausgebildet sein können, die allesamt in einen Mischraum 22 am auslaßseitigen Ende des Abgasrückführungsküh­ lers 6 münden.The cross line 17 can be divided by a partition 18 into two mutually separate line sections through which a separation of the exhaust gas streams recirculated from the two exhaust lines 19 , 20 of the respective rows of cylinders 2 , 3 takes place.

Gegebenenfalls kann bei Brennkraftmaschinen, welche aufgrund ihres Einsatzes keine Kühlung der rückgeführten Abgase benöti­ gen, die Querleitung 17 als reine Verbindungsleitung zwischen den beiden Zylinderreihen ausgeführt sein, das heißt eine durchgehende Verbindungsleitung ohne Abgasrückführungskühler oder Abgasrückführungsentnahmeanschluß. Somit hat die Verbin­ dungsleitung nur die Funktion des Druckausgleichs stromauf der Turbinen beider Abgasturbolader.If necessary, in internal combustion engines, which do not require cooling of the recirculated exhaust gases due to their use, the cross line 17 can be designed as a pure connecting line between the two rows of cylinders, that is to say a continuous connecting line without exhaust gas recirculation cooler or exhaust gas recirculation extraction connection. Thus, the connecting line only has the function of pressure equalization upstream of the turbines of both exhaust gas turbochargers.
