Abstract

The supercharger pre-compresses the induction air for an internal combustion engine and is driven by the engine itself. Its revs, relative to those of the engine, can be stagelessly regulated. Because of this, it is no longer necessary to blow out combustion air in partial load regime. Regulation may be independent of the throttle.

Description

Verbrennungsmotoren arbeiten in der Regel mit angesaugter Luft, die durch Einspritzung oder Zerstäubung von Kraftstoffen zu einem zündfähigen Gemisch aufbereitet wird. In einigen Fällen wird zur Erhöhung der spezifischen Leistung die Luft nicht angesaugt sondern durch einen Turbolader oder Kompressor vorverdichtet. Internal combustion engines usually work with intake air, the by injection or atomization of fuels to one flammable mixture is processed. In some cases, to increase the specific performance the air is not sucked but by a Turbocharger or compressor pre-compressed.

Bei der Verwendung mechanisch angetriebener Kompressoren wird ein großer Teil der Verbesserung des erzielbaren Wirkungsgrades dadurch wieder verloren, dass die Drehzahl des Kompressors immer im gleichen Verhältnis zur Motordrehzahl steht, unabhängig von der gewünschten Motorleistung. Damit muss die Regelung bei Ottomotoren über eine Drosselklappe erfolgen, wodurch die bekannten Strömungsverluste entstehen und zusätzlich muss die Überschussluftmenge im Teillastbetrieb abgeblasen werden. Damit geht ein großer Teil der Verdichterleistungsaufnahme des Kompressors verloren. When using mechanically driven compressors is a large part of the improvement of the achievable efficiency thereby lost again that the speed of the compressor is always the same Relative to the engine speed, regardless of the desired Engine performance. Thus, the control of gasoline engines on a Throttle valve, whereby the known flow losses and in addition, the excess air quantity must be in part-load operation be blown off. This is a big part of the Compressor power consumption of the compressor lost.

Mit der vorliegenden Erfindung sollen diese Verluste vermieden werden. Dazu wird der Kompressor nicht in einem konstanten Verhältnis zur Motordrehzahl angetrieben sondern proportional zur gewünschten Motorleistung, indem ein stufenloses Getriebe in den Antrieb des Kompressors integriert wird. With the present invention, these losses are to be avoided. For this purpose, the compressor is not in a constant relationship to Motor speed driven but proportional to the desired Engine power, adding a continuously variable transmission in the drive of the compressor is integrated.

Durch Verwendung eines Satellitengetriebes, das sich durch besonders schnelle Regeleingriffe auszeichnet, ist es dabei möglich, auf eine Drosselklappe und auf ein Wastegate zur Ausblasung überschüssiger Luft ganz zu verzichten. Stattdessen arbeitet die gesamte Quantitätsregelung des Verbrennungsmotors über die Kompressordrehzahl. Die Kraftstoffzufuhr kann dabei in konventioneller Weise sowohl über Saugrohr- oder Brennkammereinspritzung als auch über herkömmliche Vergaser erfolgen. By using a satellite transmission, which is characterized by special fast rule interventions, it is possible to one Throttle and on a wastegate to blow off excess air completely to renounce. Instead, the entire works Quantity control of the internal combustion engine via the compressor speed. The Fuel supply can in a conventional manner via both intake manifold or combustion chamber injection as well as over conventional carburetors respectively.

Der Drehmomentverlauf wird in einer bevorzugten Ausführung im unteren Bereich maximiert, indem die Kompressorübersetzung deutlich ins schnelle erhöht wird, während bei erreichen der höheren Drehzahlen zur Leistungsbegrenzung der Ladedruck durch Absenken der Kompressorübersetzung reduziert wird. So kann eine Leistungsbegrenzung aus Gründen der Fahrzeugsicherheit oder wegen mechanischer oder thermischer Überlastung des Motors mit weichen Kennlinienübergängen und ohne Drosselverluste erreicht werden. The torque curve is in a preferred embodiment in bottom area maximized by the compressor translation clearly into fast is increased while reaching the higher speeds to Power limitation of the boost pressure by lowering the Compressor translation is reduced. So can a power limit off For reasons of vehicle safety or because of mechanical or Thermal overload of the motor with smooth characteristic transitions and can be achieved without throttle losses.

In einer besonderen Ausführung wird die Kompressordrehzahl durch ein Kennfeld gesteuert, das die Gaspedalstellung, die Drehzahl und die Abgas-, Zylinderkopf oder Öltemperatur und/oder die Abgaszusammensetzung berücksichtigt. In a particular embodiment, the compressor speed is by a Map controlled the accelerator pedal position, the speed and the Exhaust, cylinder head or oil temperature and / or the Considered exhaust gas composition.

Bei schnellem Wechsel aus Volllast in den Schiebebetrieb, Z. B. bei abrupten Bremsmanövern, wird zusätzlich die Kraftstoffzufuhr unterbrochen, um ein schnelleres Ansprechen des Motors zu gewährleisten. Um die Bremswirkung des Motors im Schiebebetrieb z. B. bei langen Gefällestrecken zu maximieren, wird der Kompressor auf hohe Drehzahl und hohen Ladedruck geregelt, die Kraftstoffzufuhr jedoch unterbrochen. For fast change from full load to push mode, eg at abrupt braking maneuvers, the fuel supply is also interrupted, to ensure a faster response of the engine. To the Braking effect of the motor in coasting operation z. B. at long To maximize downgrades, the supercharger becomes high speed and high Boost pressure regulated, but the fuel supply interrupted.

In einer weiteren Variante wird der Kompressor nicht nur für die Ladeluft benötigt sondern auch als Sekundärluftpumpe für die Abgasverarbeitung und/oder zur Druckerzeugung von anderen Fahrzeugkomponenten wie z. B. der Luftausblasung zur Optimierung des Aquaplaningverhaltens verwendet. Die Luftmengen- und -druckverteilung regeln dabei Verzweigungsventile, den Bedarf der Gesamtluftmenge regelt die Übersetzung des Kompressorantriebes. In another variant, the compressor is not just for the charge air needed but also as a secondary air pump for the Exhaust gas processing and / or for pressure generation of other vehicle components such as B. the air blowing to optimize the aquaplaning behavior used. The air volume and pressure distribution regulate Branching valves, the demand of the total amount of air regulates the Translation of the compressor drive.

In einer anderen Ausführung wird der Kompressor über eine Abgasturbine angetrieben und das stufenlose Getriebe regelt die Kompressordrehzahl in Relation zur Turbinendrehzahl in einem Kennfeld wie oben beschrieben. In another embodiment, the compressor via a Exhaust gas turbine driven and the continuously variable transmission regulates the Compressor speed in relation to the turbine speed in a map as above described.
