Description

Die Erfindung betrifft eine Einrichtung zur Kühlung des Inneren einer Brennkraftmaschine mit einem durch eine Abgasturbine angetriebenen Aufladegebläse, insbesondere für Kraftfahrzeuge.The invention relates to a device for cooling the interior of a Internal combustion engine with a supercharger driven by an exhaust gas turbine, especially for motor vehicles.

Es ist bekannt, die bei Auf ladegruppen vorhandenen hohen Temperaturen durch Zuleitung von Luftströmen zu vermindern. Dazu kann z. B. die einem zur @"erminderung der Axialdrücke vorgesehene» Ausgleichkoll>en zugeführte Luft von niedrigem Druck benutzt werden. Es sind auch Einrichtungen bekannt, bei denen ein besonders für diesen Zweck angeordnetes Gebläse Preßluft erzeugt, mit welchem die Kühlung vorgenommen wird. Bei allen diesen Einrichtungen wird die zur Kühlung verwendete Luft unmittelbar von außen entnommen, ohne daß dabei eine Belüftung des Gehäuses der Brennkraftmasc'hine stattfindet.It is known that the high temperatures present in charging groups to be reduced by supplying air currents. For this purpose z. B. the one to @ "reduction the axial pressures provided »compensation coll> en supplied air of low pressure to be used. There are also facilities known in which a particularly for This purpose arranged fan generates compressed air with which the cooling is carried out will. In all of these devices, the air used for cooling is immediate taken from the outside without venting the housing of the internal combustion engine takes place.

Die Erfindung ermöglicht eine ausgezeichnete Kühlung und Belüftung des Gehäuses der Brennkraftmaschine und verhindert zugleich wirksam den \\'ärmeiibergang von der Altgasturbine zu dein Gebläse dadurch, daß aus dem Gehäuse der Brennkraftrnaschine Luft abgesaugt und in die Ableitung der .M>gasturbine eingeführt wird. Durch die gute Durchlüftung des Gehäuses wird außerdem <las Schmieröl und das Innere der Maschine wirksam gekühlt. Es ist möglich, eine große ?Menge Luft durch das Gehäuse zu fördern, und cla diese ölhaltige Luft in die Ableitung der Abgasturbine geführt wird, wird ein Verschmutzen von irgendwelchen Teilen verhindert. Gleichveitig werden die Abgase mit Kühlluft vermengt und gekühlt.The invention enables excellent cooling and ventilation of the housing of the internal combustion engine and at the same time effectively prevents the heat transfer from the old gas turbine to your blower in that from the housing of the internal combustion engine Air is sucked off and introduced into the outlet of the .M> gas turbine. Through the Good ventilation of the housing will also <read the lubricating oil and the inside of the Machine effectively cooled. It is possible to move a large amount of air through the case to promote, and cla led this oily air into the discharge of the exhaust gas turbine contamination of any parts is prevented. Become equivocal the exhaust gases are mixed with cooling air and cooled.

Vorteilhafterweise wird die aus dein Gehäuse entnommene Luft durch einen Raum zwischen der Altgasturbine und dein Gebläse geführt. In Verbindung mit dem Entnehmen von Luft aus dem Gehäuse der Brennkraftmaschine und Eitifülirc-n (fieser Luft in die Ableitung der Altgasturbine wird in besonders tvirksamer Weise verhindert, claß von der Altgasturbine aus Wärme an das Aufladegebläse übertragen und die Leistung der Maschine durch die Erwärmung der Aufladeluft herabgesetzt wird.The air removed from your housing is advantageously passed through led a space between the old gas turbine and your blower. Combined with the removal of air from the housing of the internal combustion engine and Eitifülirc-n (nasty Air in the discharge of the old gas turbine is prevented in a particularly effective way, heat is transferred from the old gas turbine to the supercharger and the power of the machine is reduced by the heating of the charging air.

Erfindungsgemäß wird die Gehäuseluft.durch ein zusätzliches Gebläse abgesaugt, welches zwischen (lern Aufladegebläse und der Abgasturbine abgeordnet ist.According to the invention, the housing air is provided by an additional fan extracted, which is placed between (learn the supercharger and the exhaust gas turbine is.

Durch die Einrichtung nach der Erfindung ergeben sich außer den Vorteilen einer sehr einfachen und wirksamen Belüftung des Gehäuses der Brennkraftmaschine sowie einer guten Abschirmung des Aufladegebläses gegen Erwärmung von der Abgasturbine her besonders kurze und einfache Leitungen, und außerdem wird ein besonderer Antriel) für ein die Kühlluft förderndes Gebläse vermieden.The device according to the invention also results in the advantages a very simple and effective ventilation of the housing of the internal combustion engine and good shielding of the supercharger against heating from the exhaust gas turbine especially short and simple lines, and also a special drive) avoided for a fan promoting the cooling air.

Die Zeichnung zeigt in zwei Altbildungen Ausführungsheispiele der Anordnung nach der Erfindung größtenteils im Schnitt.The drawing shows exemplary embodiments of the in two old formations Arrangement according to the invention mostly in section.

In der Abb. i sitzt auf der einen Seite der Welle i das Turbinenlaufrad 2 mit den Schaufeln. 3, auf der anderen Seite sitzt das Gebläserad .I für die Rufladung des Motors. Dieses Aufladegebläse saugt über die Kanäle 5 im Geli<iuse 6 Frischluft an und fördert diese in den (Zaum N und von da weiter zum Motor.In Fig. I, the turbine wheel sits on one side of shaft i 2 with the shovels. 3, on the other side is the fan wheel .I for the call charge of the motor. This supercharger draws in fresh air via the channels 5 in the geli <iuse 6 and conveys this into the (bridle N and from there on to the engine.

io ist das Laufrad eine: 1-Iilfsgel>läses. welches ebenfalls von der \Velle i aus angetrieben wird und zwischen dein Altgasturltinenrad 2 und dem Aufladegebläserad d sitzt. Dieses f lilfsgebläse saugt über den Stutzen 1 r, die 1Z<iurne 12 und 13 die Abluft aus dem Maschinengehäuse an und führt diese dann im Innern des Rohrstückes r 5 an der Drelle 1 mit hoher Geschwindigkeit entlang. Das Rohrstück 15 mündet in den Abzugratini i6 für die Auspuffgase des Motors, so claß die Geliiitiseluft zusammen mit den Auspuffgasen ins Freie gelangt. Da die Gehäuseluft auch die Rä unie 13 durchströmt, deren :Mündungen unmittelbar an (las Grehä tise des Aufladegebläses anschließen, so ist der dort bestehende Wä rmeühergang. der durch diels(Ilierungr7 naturgemäß nicht genügend verhitrclert \\-erden kaiirr. durch die vorhandenen finit kiilturer Luft an7efiiilten Räume wesentlich vermindert.io the impeller is a: 1-auxiliary gel> läses. which is also driven by the \ Velle i and sits between your Altgasturltinenrad 2 and the Aufladegebläserad d. This auxiliary fan sucks in the exhaust air from the machine housing via the connection 1 r, the 1Z <iurne 12 and 13 and then guides it inside the pipe section r 5 along the trough 1 at high speed. The pipe section 15 opens into the exhaust gas outlet 16 for the engine's exhaust gases, so that the geliiitiseluft and the exhaust gases get into the open air. Since the housing air also flows through the rooms 13, the mouths of which are directly connected to (read the Grehä tise of the supercharger blower, so the heat process existing there is. Which is naturally not sufficiently hardened by the (Ilierungr7 \\ - earth kaiirr. By the existing finite Cooler air in cold rooms is significantly reduced.

Bei dem in der Abb. r siclitliaren Hilfsgebläse handelt es sich um ein @1@ialgel>lä se. Die .11>1t. 2 zeigt ein Ausführungsbeispiel, hei welchem für das Hilfsgebläse eilt Schleu<lergel>läscrad 20 verwetrdet wird. Die diesem Gebläsera(I entsl»-ecbende Gestaltung des Gebläsegelrä trses ist dabei derart, daß ein Teil der geförderten Luft über den Ringkanal 21 unmittelbar in den Abzugrauni 16 für die Auspuffgase gelangt, während der andere Teil durch den Raum 22 in das die Tur-1>irienwelle i konzentrisch umgeltende Rohrstück 23 gedrückt wird und von da in den Abzugratim 16 gelangt. Bei dieser Ausführung ist eitre wirksame hiililtitig der Turltinenwelle gewährleistet.The auxiliary fan shown in the illustration r is a @ 1 @ ialgel> lä se. The .11> 1t. 2 shows an exemplary embodiment in which Schleu <lergel> läscrad 20 is used for the auxiliary fan. The design of the blower control mechanism for this blower is such that part of the air conveyed via the ring duct 21 directly reaches the exhaust 16 for the exhaust gases, while the other part passes through the space 22 into the door 1> irienwelle i concentrically circulating pipe section 23 is pressed and from there reaches the withdrawal rate 16. In this embodiment, an effective support of the turltine shaft is guaranteed.
