Abstract
Description
Die vorliegende Erfindung betrifft Verbrennungsmotor mit mehreren, mindestens zwei, Zylindern, deren Abgase mit Krümmern zu mindestens einer ersten und zweiten Abgasgruppe zusammenfassbar sind und zwei Frischluftverdichtereinheiten, die von den Abgasen antriebbar sind und die Frischluft des Verbrennungsmotors verdichten, wobei der erste Frischluftverdichtereinheit durch ein Absperrmittel abschaltbar ist.The The present invention relates to an internal combustion engine having a plurality, at least two, cylinders whose exhaust gases with manifolds to at least a first and second exhaust group are summarized and two fresh air compressor units, the are driven by the exhaust gases and the fresh air of the engine compact, wherein the first fresh air compressor unit by a Shut-off is switched off.
Bei
Mehrzylindermotoren werden jeweils die Hälfte der Zylinder zu jeweils
einer Abgasgruppe zusammengefaßt,
so dass zwei Abgasgruppen entstehen. Die Abgase dieser Abgasgruppen
treiben heutzutage oftmals Turbinen zweier baugleicher Turbolader
an, um die für
den Verbrennungsprozeß benötigte Frischluft
zu verdichten. Da die Turbolader im unteren bis mittleren Drehzahlbereich
nicht optimal arbeiten, ist es mittlerweile Stand der Technik, in
diesen Drehzahlbereichen die Abgasgruppen zusammenzufassen und nur
noch einen Turbolader zur Verdichtung der Frischluft zu betreiben.
Der zweite Turbolader wird mit einem minimalen Abgasstrom lediglich auf
Drehzahl gehalten. Die Zusammenfassung der Abgasströme, wie
sie beispielsweise in der
Es war deshalb die Aufgabe der vorliegenden Erfindung einen Verbrennungsmotor zur Verfügung zustellen, der die Nachteile des Standes der Technik nicht aufweist.It Therefore, the object of the present invention was an internal combustion engine to disposal deliver, which does not have the disadvantages of the prior art.
Gelöst wird die Aufgabe mit einem Verbrennungsmotor gemäß Patentanspruch 1, bevorzugte Ausführungsform des erfindungsgemäßen Verbrennungsmotors sind in den Patentansprüchen 2 bis 8 beansprucht.Is solved the task with an internal combustion engine according to claim 1, preferred embodiment the internal combustion engine according to the invention are in the claims 2 to 8 claimed.
Es war für den Fachmann überaus erstaunlich und nicht zur erwarten, dass es mit dem erfindungsgemäßen Verbrennungsmotor gelingt auch in mittleren bis unteren Drehzahlbereich Turbolader mit guten Wirkungsgraden zur Verfügung zustellen, ohne dass die beiden Abgasgruppen gasseitig zusammengeführt werden müssen. Der erfindungsgemäße Motor ist einfach und kostengünstig herzustellen und zu betreiben.It was for the expert very much amazing and not to expect it with the internal combustion engine according to the invention also succeeds in medium to low speed turbocharger with good efficiencies available without the Both exhaust groups must be merged on the gas side. Of the Motor according to the invention is easy and inexpensive manufacture and operate.
Erfindungsgemäß weist der Verbrennungsmotor eine erste und eine zweite Frischluftverdichtereinheit auf, wobei die erste Frischluftverdichtereinheit mit Absperrmitteln abschaltbar bzw. mit so wenig Abgas beaufschlagbar ist, dass sie nur auf Drehzahl gehalten wird aber keine Verdichtung erfolgt. Die zweite Frischluftverdichtereinheit weist hingegen zwei Antriebsmittel auf, die mit den Abgasen zusammenwirken.According to the invention the internal combustion engine, a first and a second fresh air compressor unit on, wherein the first fresh air compressor unit with shut-off can be switched off or acted upon with so little exhaust gas that they only held at speed but no compression occurs. The second Fresh air compressor unit, however, has two drive means, which interact with the exhaust gases.
Vorzugsweise wird im unteren bis mittleren Drehzahlbereich, im unteren Lastbereich und/oder bei niedriger Drehzahl im oberen Lastbereich des Verbrennungsmotors, dass eine Antriebsmittel mit den Abgasen der ersten Abgasgruppe und das zweite Antriebsmittel mit den Abgasen der zweiten Abgasgruppe beaufschlagt. Diese bevorzugte Ausführungsform der vorliegenden Erfindung hat den Vorteil, dass auch im unteren bis mittleren Drehzahlbereich die Abgase der beiden Abgasgruppen nicht zusammengefaßt werden müssen, um den Turbolader zu betreiben. Im oberen Drehzahlbereich des Verbrennungsmotors hingegen werden vorzugsweise beide Antriebsmittel mit den Abgasen der zweiten Abgasgruppe beaufschlagt. In diesem Drehzahlbereich ist die erste Frischluftverdichtereinheit nicht mehr abgasseitig abgeschaltet, so dass diese Verdichtereinheit mit den Abgasen der ersten Abgasgruppe beaufschlagt wird.Preferably is in the lower to medium speed range, in the lower load range and / or at low speed in the upper load range of the internal combustion engine, that a drive means with the exhaust gases of the first exhaust gas group and the second drive means with the exhaust gases of the second exhaust group applied. This preferred embodiment of the present invention Invention has the advantage that even in the lower to medium speed range the exhaust gases of the two exhaust groups are not summarized have to, to operate the turbocharger. In the upper speed range of the internal combustion engine on the other hand, preferably both drive means with the exhaust gases the second exhaust gas group acted upon. In this speed range the first fresh air compressor unit is no longer exhaust switched off, so that this compressor unit with the exhaust gases of the first exhaust gas group is acted upon.
Vorzugsweise ist die Verdichterleistung der beiden Verdichtereinheiten im wesentlichen gleich groß.Preferably is the compressor performance of the two compressor units substantially same size.
In einer bevorzugten Ausführungsform der vorliegenden Erfindung ist die zweite Frischluftverdichtereinheit ein Turbolader mit zwei Schnecken, die jedoch lediglich ein Laufrad zur Verdichtung der Frischluft antreiben.In a preferred embodiment The present invention is the second fresh air compressor unit a turbocharger with two screws, but only one impeller drive to compress the fresh air.
In einer anderen bevorzugten Ausführungsform weist die zweite Verdichtereinheit zwei Turbolader auf, die besonders bevorzugt ungefähr jeweils 50% jeweils der Verdichterleistung der zweiten Verdichtereinheit zur Verfügung stellen.In another preferred embodiment The second compressor unit has two turbochargers, which are particularly preferably about each 50% each of the compressor capacity of the second compressor unit to disposal put.
Vorzugsweise weist der erfindungsgemäße Verbrennungsmotor Stellorgane auf, die so einstellbar sind, dass an der Frischluftseite der abgeschalteten Verdichtereinheit immer Ladedruck anliegt. Diese bevorzugte Ausführungsform der vorliegenden Erfindung hat den Vorteil, dass bei zuschalten dieser Verdichtereinheit sofort der entsprechende Ladedruck vorliegt und nicht erst aufgebaut werden muß, was die Ansprechzeit dieses Verdichters reduziert.Preferably has the internal combustion engine according to the invention Actuators that are adjustable so that on the fresh air side the switched-off compressor unit always applies boost pressure. This preferred embodiment The present invention has the advantage that when switch on this compressor unit immediately the corresponding boost pressure is present and does not have to be built first, what the response time of this Reduced compressor.
