Description

Die Erfindung betrifft die Kühlung eingekapselter Brennkraftmaschinen in Schienentriebwagen mit Luft, die der Einkapselung mit Überdruck zugeführt wird.The invention relates to the cooling of encapsulated internal combustion engines in rail cars with air, which is supplied to the encapsulation with overpressure.

Die Nachteile der bekannten Einrichtungen sind darin zu sehen, daß bei Luftzuführung durch den Staudruck, der durch die Fahrzeuggeschwindigkeit entsteht, nicht immer genügend Luft der Brennkraftmaschine zugeführt wird, besonders wenn die Fahrzeuggeschwindigkeit infolge erhöhten Widerstandes stark absinkt. Die Kühlung und die Belüftung der Brennkraftmaschine ist bei den bekannten Einrichtungen, auch bei solchen mit Lüftern, die unabhängig von der Brennkraftmaschine angetrieben werden, deshalb noch schlecht, weil der Maschinenraum im Verhältnis zur Größe der Brennkraftmaschine zu groß ist und die zugeführte Luft nicht mit genügender Geschwindigkeit entlang der hauptsächlich zu kühlenden Teile geführt wird.The disadvantages of the known devices can be seen in the fact that in the case of air supply through the dynamic pressure created by the vehicle speed, not always enough air is supplied to the internal combustion engine, especially if the vehicle speed drops sharply as a result of increased resistance. The cooling and the ventilation of the internal combustion engine is in the known devices, too for those with fans that are driven independently of the internal combustion engine, therefore still bad, because the engine room in relation to the size of the internal combustion engine is too large and the air supplied does not travel at sufficient speed the parts that are mainly to be cooled.

Durch die Erfindung wird gute, geringen Raum beanspruchende Führung der Kühlluft, eine ausgezeichnete Belüftung der Brennkraftmaschine und zugleich eine der Drehzahl der Brennkraftmaschine angepaßte Luftzuführung dadurch erreicht, daß die Frischluftzuleitung zu einem von der Brennkraftmaschine angetriebenen Lüfter eine Ummantelung der Auspuffleitung umgibt und der Überschuß der von dem Lüfter geförderten Luft durch eine zwangsweise Führung in dieser Ummantelung entlang- der Auspuffrohre ausgestoßen wird.The invention provides good, space-consuming guidance the cooling air, excellent ventilation of the internal combustion engine and at the same time an air supply adapted to the speed of the internal combustion engine is achieved by that the fresh air supply line to a fan driven by the internal combustion engine a jacket surrounds the exhaust pipe and the excess of the fan conveyed air by a forced guide in this casing along the Exhaust pipes is ejected.

Erfindungsgemäß sind die Ansaugöffnungen der Frischluft möglichst hoch über der Fahrbahn angeordnet. Vorteilhafterweise sind die Ansaugöffnungen um die Austrittsöffnungen herum und tiefer als dieselben angeordnet.According to the invention, the intake openings of the fresh air are as possible arranged high above the roadway. The suction openings are advantageously around the outlets are arranged around and lower than the same.

Die Zeichnung zeigt ein schematisch dargestelltes Ausführungsbeispiel der Erfindung größtenteils im Schnitt.The drawing shows a schematically illustrated embodiment of the invention mostly in section.

In der Zeichnung stellt 2 die Brennkraftmaschine eines Schienentriebwagens i dar. Die Einkapselung 3 umgibt den Motor und ist möglichst dicht. Am Ende der Zuführungsleitung 4 der .Einrichtung befindet sich der von der Brennkraftmaschine 2 angetriebene Lüfter 5. Den Anfang der Zuführungsleitung 4 bilden die auf dem Dach des Triebwagens konzentrisch um die Austrittsöffnung 9 angeordneten Ansaugöffnungen 6. An Stelle dieser kann auch ein einziger ringförmiger Querschnitt vorgesehen werden. Die Auspuffleitungen 7 der Brennkraftmaschine sind von einer Ummantelung 8 umgeben und innerhalb der Zuführungsleitung 4 nach oben geführt. Die gemeinsame LuftundAuspuffaustrittsöffnungg befindet sich in einem Abstand über und in der Mitte der Ansaugöffnungen 6. Die Einkapselung kann auch nur einen Teil der Brennkraftmaschine, z. B. die Zylinder, umgeben. Die Ummantelung der Auspuffrohre nimmt dann ihren Anfang in dem durch die Einkapselung der Zylinder gebildeten Raum. Beim Ingaugsetzen des Motors beginnt der Lüfter 5 Luft durch die Ansaugöffnungen 6 und die Zuführungsleitung 4 anzusaugen und drückt diese in den von der Einkapselung 3 gebildeten Raum. Durch die besondere Anordnung der Ansaugöffnun- gen 6, nämlich konzentrisch um und etwas tiefer als -die Austrittsöffnung 9, wird mit Sicherheit vermieden, daß die ausgestoßene erwärmte Luft wieder angesaugt wird. Die Förderleistung des Lüfters ist so bemessen, daß trotz der zweckmäßig möglichst klein gehaltenen Undichtheiten der Einkapselung 3 und trotz des Luftverbrauchs der Brennkraftmaschine genügend Luft durch die Ummantelung der Auspuffleitungen gedrückt wird, so daß dieselben gut gekühlt werden. Der Querschnitt der Ummantelung 8 wird nach der Erfindung so gewählt, daß bei der festgelegten Förderleistung des Lüfters in der Einkapselung noch ein Überdruck entsteht, der das Eindringen von Staub und Schmutz verhindert.In the drawing, 2 represents the internal combustion engine of a railroad car i. The encapsulation 3 surrounds the engine and is as tight as possible. At the end of the feed line 4 of the device is the fan 5 driven by the internal combustion engine 2. The beginning of the feed line 4 is formed by the suction openings 6 arranged concentrically around the outlet opening 9 on the roof of the railcar. Instead of these, a single annular cross section can be provided will. The exhaust lines 7 of the internal combustion engine are surrounded by a casing 8 and are guided upward within the supply line 4. The common air and exhaust outlet openingg is located at a distance above and in the middle of the intake openings 6. The encapsulation can also only be part of the internal combustion engine, e.g. B. the cylinder surrounded. The covering of the exhaust pipes then begins in the space formed by the encapsulation of the cylinders. When the motor is started, the fan 5 begins to suck in air through the suction openings 6 and the supply line 4 and presses it into the space formed by the encapsulation 3. The special arrangement of the suction openings 6, namely concentrically around and somewhat deeper than the outlet opening 9, reliably prevents the expelled heated air from being sucked in again. The flow rate of the fan is such that, in spite of the leaks in the encapsulation 3, which are expediently kept as small as possible, and despite the air consumption of the internal combustion engine, enough air is forced through the casing of the exhaust pipes so that they are well cooled. The cross-section of the casing 8 is selected according to the invention so that at the specified delivery rate of the fan in the encapsulation there is still an overpressure which prevents the penetration of dust and dirt.

Da die Lüfterförderleistung proportional der Motordrehzahl verläuft, ist mit der Erfindung eine Einrichtung geschaffen, die unabhängig von der Geschwindigkeit des Fahrzeuges i. die Füllung und damit die Leistung der Brennkraftmaschine gewährleistet, 2. eine gute Belüftung der Maschinenlage erzeugt, 3. die Maschine mit den Triebwerksteilen vor Verschmutzen sichert und 4. mit einfachsten Mitteln die Auspuffanlage der Brennkraftmaschine kühlt.Since the fan delivery rate is proportional to the engine speed, the invention provides a device that is independent of the speed of the vehicle i. ensures the filling and thus the performance of the internal combustion engine, 2. creates good ventilation of the machine position, 3. secures the machine with the engine parts from contamination and 4. cools the exhaust system of the internal combustion engine with the simplest means.

Durch die doppelte Ummantelung der Auspuffanlage und der in diesen Mantelräumen stetigen und lebhaften Luftbewegung ist der Fahrzeugraum ausgezeichnet gegen die Wärme und auch eventuell den Geruch der Auspuffanlage isoliert.Because of the double coating of the exhaust system and the one in it The vehicle compartment is excellent with constant and lively air movement insulated against the heat and possibly the smell of the exhaust system.
