Description
Zweitaktverbrennungskraftmaschine mit Abgasturbine und einer von dieser antreibbaren Spülpumpe Es ist bei Zweitaktbrennkraftmaschinen bereits vorgeschlagen worden, die Abgase zum Antrieb einer Abgasturbine zu verwenden, die wiederum die Spülpumpe der Brennkraftmaschine antreibt. Diese Maßnahme ist jedoch nur für den normalen Betrieb der Brennkraftmaschine, nicht aber für das Anfahren geeignet. Man hat deshalb weiter vorgeschlagen, für die Zeitdauer des Anfahrens der Brennkraftmaschine, währenddessen die Spülpumpe bereits Ladeluft liefern muß, als Spülpumpenantrieb einen - Elektromotor zu verwenden. Dies erweist sich jedoch als unwirtschaftlich, weil dadurch die Anlagekosten vermehrt werden, sofern der Elektromotor nicht ohnehin für den Antrieb notwendig ist, und weil hierdurch die Gesamtanlage von Stromquellen in Abhängigkeit gebracht wird. Wo diese Stromquellen nicht zur Verfügung stehen, ist daher die Anlage nicht zu verwenden.Two-stroke internal combustion engine with exhaust gas turbine and one of these Drivable scavenging pump It has already been proposed for two-stroke internal combustion engines been to use the exhaust gases to drive an exhaust gas turbine, which in turn the Drives scavenging pump of the internal combustion engine. However, this measure is only for the normal operation of the internal combustion engine, but not suitable for starting. Man has therefore further proposed, for the duration of the start-up of the internal combustion engine, while the scavenging pump must already deliver charge air as a scavenging pump drive to use an - electric motor. However, this proves to be uneconomical, because this increases the investment costs, provided the electric motor is not anyway is necessary for the drive, and because it makes the entire system of power sources is brought into dependency. Where these power sources are not available, the system is therefore not to be used.
Gemäß der Erfindung wird mit der Abgasturbine eine besondere Druckluft- oder Druckgasturbine verbunden, die während des Anlassens der Brennkraftmaschine zum Antrieb der Spülpumpe in Betrieb genommen, nach Übergang auf den normalen Betrieb dagegen abgeschaltet wird. Das zum Betrieb dieser Luftturbine verwendete Druckmittel ist bei Dieselmaschinen in Form von Anlaßluft stets vorhanden. Die Anlage ist daher von der Verwendung besonderer Kraftquellen außerhalb der Brennkraftmaschine frei. Das zum Betrieb der Luftturbine verwendete Druckmittel kann vorgewärmt werden, um eine Abkühlung auf zu tiefe Temperaturen, die zu Eisbildungen führen können, zu vermeiden.According to the invention, the exhaust gas turbine is a special compressed air or pressure gas turbine connected during the starting of the internal combustion engine Started to drive the flushing pump after switching to normal operation on the other hand is switched off. The pressure medium used to operate this air turbine is always present in diesel engines in the form of starting air. The plant is therefore free from the use of special power sources outside the internal combustion engine. The pressure medium used to operate the air turbine can be preheated to cooling down to temperatures that are too low, which can lead to ice formation avoid.
Die Betreibung der Abgasturbine während des Anfahrens der Brennkraftmaschine mit einem anderen aufgespeicherten Druckmittel. z. B. Preßluft, ist nicht Gegenstand der Erfindung.The operation of the exhaust gas turbine while the internal combustion engine is starting up with another stored pressure medium. z. B. compressed air is not the subject the invention.
In der Zeichnung ist die Erfindung schematisch an einem Ausführungsbeispiel dargestellt.In the drawing, the invention is shown schematically in an exemplary embodiment shown.
a sind die Zylinder einer Zweitaktbrennkraftmaschine, deren Auspuffleitungen b in einen gemeinsamen Auspuffsammler c münden. Dieser letztere ist an eine zweckmäßig nur zum Teil beaufschlagte Abgasturbine d bekannter Bauart angeschlossen, die von den Abgasen betrieben wird. Die Abgase verlassen die .Turbine durch die Leitung e, die entweder in das Freie oder nach einem Abwärmev erwerter führen kann, wo sie weiterhin zu beliebigen Zwecken ausgenutzt werden können. Mit der Welle der Abgasturbine ist die Spülpumpe f gekuppelt, die in dieseln Falle vorzugsweise aus einem kreiselförmigen Gebläse bestehen kann, das die Luft bei g ansaugt und durch die Leitung h nach dem Spülluftaufnehmer i. drückt.a are the cylinders of a two-stroke internal combustion engine, their exhaust lines b open into a common exhaust collector c. This latter is expedient to one only partially acted upon exhaust gas turbine d of known design connected by the exhaust gases is operated. The exhaust gases leave the turbine through the line e, which can lead either to the open air or to a waste heat recovery unit, where they are can continue to be used for any purpose. With the shaft of the exhaust gas turbine the flushing pump f is coupled, which in this case preferably consists of a gyro-shaped There may be a fan that sucks in the air at g and through the line h after Purge air sensor i. presses.
Neben der Abgasturbine ist eine besondere Druckluft- oder Druckgasturbine L vorgesehen, deren Laufrad auf der Turbinenwelle sitzt. Durch eine Leitung in, steht diese Turbine mit einem Druckluft- oder Druckgasbehälter in Verbindung, während die Abluft bzw. das Abgas durch die Leitung n entweicht. Während des Anfahrens der Brennkraftmaschine wird durch Öffnen eines in die Leitung in eingeschalteten Absperrorganes Druckluft oder Druckgas auf die Turbine! geleitet und dadurch die Spülpumpe in Betrieb gesetzt. Das Laufrad der Abgasturbine läuft während dieser Zeit leer mit. Sobald die Brennkraftmaschine angesprungen ist, wird die Druckluftturbine abgeschaltet, und der Antrieb der Spülluftpumpe erfolgt nunmehr durch die Abgasturbine, während das Laufrad der Druckluftturbine leer mitläuft.In addition to the exhaust gas turbine, there is a special compressed air or pressure gas turbine L is provided, the impeller of which sits on the turbine shaft. Through a line in, stands this Turbine with a compressed air or compressed gas tank in Connection, while the exhaust air or the exhaust gas escapes through line n. While the start-up of the internal combustion engine is switched on by opening one in the line in Shut-off device Compressed air or pressurized gas on the turbine! guided and thereby the Rinsing pump started. The impeller of the exhaust gas turbine runs during this Time empty with. As soon as the internal combustion engine has started, the compressed air turbine is switched off, and the purge air pump is now driven by the exhaust gas turbine, while the impeller of the compressed air turbine runs idle.
Gegebenenfalls kann auch eine Kupplungseinrichtung vorgesehen sein, die gestattet, nach Übergang auf den normalen Betrieb die Verbindung des Laufrades der Druckluftturbine mit der Turbinenwelle zu lösen, so daß die Druckluftturbine ganz ausgeschaltet ist. Die Art der verwendeten Spülluftpumpen ist nebensächlich. Vorzugsweise sind jedoch wegen des direkten Antriebes durch die Turbine Kreiselgebläse geeignet.If necessary, a coupling device can also be provided, which allows the connection of the impeller after the transition to normal operation to solve the air turbine with the turbine shaft, so that the air turbine is completely off. The type of purge air pumps used is irrelevant. However, because of the direct drive by the turbine, centrifugal fans are preferred suitable.
