Abstract

The turbocharger is driven by a turbine (4) in the exhaust duct and drives a compressor (5) in the inlet manifold. An electric motor (2) is coupled to the turbocharger shaft (1) when the engine speed is below a set level. This provides effective turbocharging even with insufficient engine speed. The electric motor is coupled to the turbine shaft by a gearing and a freewheel clutch. Hydraulic transmission can also be used. For an additional benefit the electric motor can be driven as a generator at higher engine speeds, replacing the conventional generator for the engine. ADVANTAGE - Effective turbo-charging at all engine speeds.

Description

Es ist bekannt, daß Abgasturbolader bei niedriger Motordrehzahl ungenügenden Ladedruck aufbauen oder aber das Ansprechverhalten der Turbomotoren durch komplizierte Steuereinrichtungen am Turbolader ver­ bessert werden muß.It is known that turbochargers at low Engine speed build up insufficient boost pressure or but the response behavior of the turbo engines complicated control devices on the turbocharger ver needs to be improved.

Der Erfindung liegt nun die Aufgabe zugrunde, das Ansprechverhalten von Turbomotoren auf einfache und preiswerte Weise zu verbessern.The invention is based on the object Responsiveness of turbo engines to simple and cheap way to improve.

Diese Aufgabe wird dadurch gelöst, daß ein Elektro­ motor mit dem Laufzeug (Welle, Turbinenräder) des Turboladers gekoppelt wird. Bei niedriger Drehzahl des Verbrennungsmotors wird über eine Steuerung der Elektromotor aktiviert und dadurch die Turbolader­ welle beschleunigt. Der Aufbau des Ladedrucks erfolgt jetzt spontan und unabhängig von der Drehzahl des Verbrennungsmotors. Die Gaswechselarbeit des Verbren­ nungsmotors wird zudem durch die angesaugten Abgase erleichtert.This object is achieved in that an electric motor with the running gear (shaft, turbine wheels) of the Turbocharger is coupled. At low speed of the internal combustion engine is controlled by a controller Electric motor activated and thereby the turbocharger wave accelerates. The boost pressure is built up now spontaneously and regardless of the speed of the Internal combustion engine. The gas exchange work of burning engine is also sucked in by the exhaust gases facilitated.

Die Übertragung des Elektromotor-Drehmoments auf die Laderwelle kann entweder durch eine feste oder trenn­ bare Verbindung erfolgen. Bei trennbarer Verbindung können sowohl mechanische oder hydraulische Kupplungen eingesetzt werden als auch eine Freilaufvorrichtung, die die Verbindung löst sobald die angetriebene Welle (Laderwelle) sich schneller dreht als die treibende (E-motorwelle).The transmission of the electric motor torque to the The supercharger shaft can either be fixed or separated bare connection. With separable connection can be both mechanical or hydraulic couplings be used as well as a freewheel device, which releases the connection as soon as the driven shaft (Supercharger shaft) turns faster than the driving one (Electric motor shaft).

Hat der Verbrennungsmotor genügend Drehzahl erreicht, so kann der Elektromotor entweder wie im vorigen Ab­ satz beschrieben ausgekoppelt und abgeschaltet werden oder aber über den Abgasstrom angetrieben, weiterlaufen und als Generator arbeiten. Hierbei wird die kinetische Energie der Abgase in elektrische Energie umgewandelt, was den Wegfall einer separaten Lichtmaschine zur Folge hat.If the internal combustion engine has reached enough speed, so the electric motor can either as in the previous Ab described described can be decoupled and switched off  or driven by the exhaust gas flow, continue to run and work as a generator. Here the kinetic Energy of the exhaust gases converted into electrical energy, which results in the elimination of a separate alternator Has.

Die mit der Erfindung erzielten Vorteile bestehen darin, daß der optimale Ladedruck spontan aufgebaut ist und damit das Drehmoment des Verbrennungsmotors im unteren Drehzahlbereich ansteigt. Bestehende Turboladerkonstruk­ tionen können nach geringfügiger Änderung weiterver­ wendet werden. Eine Neudimensionierung bzw. Neukonstruk­ tion ist nicht zwingend notwendig.The advantages achieved by the invention are that the optimal boost pressure is built up spontaneously and thus the torque of the internal combustion engine in the lower Speed range increases. Existing turbocharger construction After minor changes, be applied. A redimensioning or redesign tion is not absolutely necessary.
