Abstract
Description
Die Erfindung betrifft eine Brennkraftmaschine gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to an internal combustion engine according to the preamble of the claim 1.
Zur Steigerung des Wirkungsgrads und der Leistung von Brennkraftmaschinen ist es aus dem Stand der Technik bereits bekannt, Brennkraftmaschinen mit einer Abgasturboaufladung auszurüsten. Bei einer Abgasturboaufladung wird aus einem Motor abgeleitetes Abgas in einer Turbine entspannt, wobei die Turbine einen Verdichter antreibt, in welchem dem Motor zuzuführende Verbrennungsluft verdichtet wird. Zwischen den Verdichter und den Motor ist ein Ladeluftkühler geschaltet, um die verdichtete Verbrennungsluft auf eine definierte Temperatur abzukühlen. Über eine derartige Abgasturboaufladung kann der Wirkungsgrad von Brennkraftmaschinen, die zum Beispiel einen Dieselmotor oder einen Gasmotor umfassen, gesteigert werden.to Increase the efficiency and performance of internal combustion engines It is already known from the prior art, internal combustion engines equipped with an exhaust turbocharger. In an exhaust turbocharger is derived from an engine-derived exhaust gas in a turbine, wherein the turbine drives a compressor in which the engine supplied Combustion air is compressed. Between the compressor and the Engine is a charge air cooler switched to the compressed combustion air to a defined Temperature to cool. Over a Such Abgasturboaufladung can the efficiency of internal combustion engines, the For example, a diesel engine or a gas engine, increased become.
Die oben beschriebene, einstufige Abgasturboaufladung mithilfe einer Turbine sowie eines Verdichters stößt hinsichtlich des realisierbaren Ladedrucks sowie des realisierbaren Wirkungsgrads an ihre wirtschaftlich darstellbaren Grenzen, so dass zu einer weiteren Verbesserung des Wirkungsgrads und der Leistung von Brennkraftmaschinen mehrstufige, insbesondere zweistufige, Abgasturboaufladungen durchgeführt werden. Bei einer zweistufigen Abgasturboaufladung ist dem Motor der Brennkraftmaschine eine Hochdruckladeeinrichtung sowie eine Niederdruckladeeinrichtung zugeordnet. Die Hochdruckladeeinrichtung umfasst eine Hochdruckturbine, in welcher ein den Motor verlassender Abgasstrom entspannt wird. Die Hochdruckturbine treibt einen Hochdruckverdichter an, der einen dem Motor zuzuführenden Verbrennungsluftstrom verdichtet. Zwischen den Hochdruckverdichter und den Motor ist wiederum ein Ladeluftkühler geschaltet. Die Niederdruckladeeinrichtung verfügt über eine Niederdruckturbine, in welcher der die Hochdruckturbine verlassende Abgasstrom nachentspannt wird.The described above, single-stage turbocharger using a Turbine as well as a compressor encounters in terms of realizable Boost pressure as well as the realizable efficiency to their economic representable boundaries, allowing to further improve the Efficiency and performance of internal combustion engines multi-stage, in particular two-stage, turbocharged turbochargers are carried out. In a two-stage Exhaust Turbo Charging is the engine of the internal combustion engine, a high-pressure charging device and associated with a low pressure charging device. The high pressure charging device includes a high-pressure turbine, in which a leaving the engine Exhaust gas flow is relaxed. The high pressure turbine drives a high pressure compressor on, one to be supplied to the engine Combustion air flow compressed. Between the high pressure compressor and the engine is in turn connected to a charge air cooler. The low pressure charging device has one Low-pressure turbine, in which the leaving the high-pressure turbine Exhaust gas stream is relieved.
Die Niederdruckturbine treibt einen Niederdruckverdichter an, in welcher der dem Motor über den Hochdruckverdichter zuzuführende Verbrennungsluftstrom vorverdichtet wird. Zwischen den Niederdruckverdichter und den Hochdruckverdichter ist dabei üblicherweise ein weiterer Ladeluftkühler geschaltet.The Low-pressure turbine drives a low-pressure compressor, in which the engine over the High-pressure compressor to be supplied Combustion air flow is pre-compressed. Between the low pressure compressor and the high-pressure compressor is usually connected another intercooler.
Bei einer Brennkraftmaschine mit einer zweistufigen Abgasturboaufladung sind demnach dem Motor der Brennkraftmaschine zwei Ladeeinrichtungen, nämlich eine Hochdruckladeeinrichtung und eine Niederdruckladedruckeinrichtung, zugeordnet, die nach dem Stand der Technik beide am Motor angebaut werden müssen. Liegt ein Motor in V-Bauweise vor, der je Zylinderreihe über eine separate Abgasturboaufladung verfügt, so würde sich bei einer zweistufigen Abgasturboaufladung die Anzahl der am Motor zu befestigenden Ladeeinrichtungen auf vier erhöhen, nämlich auf je Zylinderreihe jeweils eine Hochdruckladeeinrichtung und eine Niederdruckladeeinrichtung.at an internal combustion engine with a two-stage turbocharger Accordingly, the engine of the internal combustion engine are two charging devices, namely a high-pressure charging device and a low-pressure charging device, associated with the prior art both mounted on the engine Need to become. If an engine in V-construction, which per cylinder row on a separate turbocharging has, so would be in a two-stage Turbocharging the number of charging devices to be attached to the engine increase to four, namely on each cylinder row each have a high-pressure charging device and a Low-pressure charger.
Erhöht sich die Anzahl der am Motor zu befestigenden bzw. zu lagernden Ladeeinrichtungen, so kann dies infolge des nicht unerheblichen Platzbedarfes der Ladeeinrichtungen zu Problemen bei der Installation derselben führen. Weiterhin kann die Festigkeit und das Schwingungsverhalten der Brennkraftmaschine negativ beeinträchtigt werden.Increases the number of charging devices to be mounted or stored on the motor, see above This may be due to the considerable space requirements of the charging devices lead to problems with the installation of the same. Furthermore, the strength and the vibration behavior of the internal combustion engine are adversely affected.
Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zugrunde, eine neuartige Brennkraftmaschine zu schaffen.Of these, Based on the present invention, the problem is based to create a novel internal combustion engine.
Dieses Problem wird durch eine Brennkraftmaschine gemäß Patentanspruch 1 gelöst. Erfindungsgemäß ist die Niederdruckladeeinrichtung als separates Modul ausgebildet und vom Motor derart entkoppelt, dass die Niederdruckladeeinrichtung an einem separaten Rahmen bzw. Gestell gelagert ist.This Problem is solved by an internal combustion engine according to claim 1. According to the invention Low-pressure charging device designed as a separate module and from Motor decoupled such that the low pressure charging device to a separate frame or frame is stored.
Im Sinne der hier vorliegenden Erfindung wird vorgeschlagen, bei einer Brennkraftmaschine mit einer mindestens zweistufigen Abgasturboaufladung die Niederdruckladeeinrichtung als separates Modul auszubilden und vom Motor derart zu entkoppeln, dass die Niederdruckladeeinrichtung an einem separaten Tragrahmen bzw. Traggestell gelagert ist. Auf diese Art und Weise wird die Festigkeit und das Schwingungsverhalten der Brennkraftmaschine gegenüber einer einstufig aufgeladenen Brennkraftmaschine nicht verändert. Platzprobleme bei der Installation bzw. Montage der Niederdruckladeeinrichtung werden vermieden. Da die Niederdruckladeeinrichtung als separates Modul ausgebildet ist, können bestehende Brennkraftmaschinen mit einstufiger Abgasturboaufladung einfach nachgerüstet werden, ohne dass am Motor oder an der Hochdruckladeeinrichtung konstruktive Änderungen erforderlich wären.in the For the purposes of the present invention, it is proposed in a Internal combustion engine with at least two-stage turbocharging form the low pressure charging device as a separate module and decouple from the engine so that the low pressure charging device is mounted on a separate support frame or support frame. On This way is the strength and vibration behavior the engine opposite a single-stage supercharged internal combustion engine not changed. space problems during installation or assembly of the low-pressure charging device avoided. Because the low pressure charging device as a separate module is trained, can existing internal combustion engines with single-stage turbocharging simply retrofitted without being on the engine or on the high-pressure charging device constructive changes would be required.
Vorzugsweise ist die Hochdruckladeeinrichtung zusammen mit dem Motor an einem gemeinsamen Rahmen bzw. Gestell gelagert, wobei die Hochdruckladeeinrichtung und der Motor insbesondere als ein Modul ausgebildet sind.Preferably is the high pressure charging device together with the engine on one stored common frame or frame, wherein the high-pressure loading device and the motor are in particular designed as a module.
