In der Abgasnebenleitung ist eine Drosselklappe angeordnet, die die Abgasleitung verschließt, wenn sich der Katalysator in normalen Betriebsbereichen befindet, und die Abgasnebenleitung wieder öffnet, wenn sich der Katalysator in unverträglichen Betriebsbereichen befindet. Diese Steuerung erfolgt in Abhängigkeit von der Temperatur des Katalysators. Hierbei hat sich der zusätzliche Kostenaufwand als nachteilig erwiesen, der durch diese Einrichtung zur Vermeidung von Beschädigungen des Katalysators infolge von überbelastung verursacht wird.

No. 3,037,344), which has an exhaust gas bypass line bypassing the catalytic converter having. There is a throttle valve in the secondary exhaust line arranged that closes the exhaust line when the catalytic converter is in normal operating ranges, and the exhaust gas bypass opens again when the catalytic converter is in incompatible operating ranges. This control takes place as a function of the temperature of the catalytic converter. This has increased the additional cost proved to be disadvantageous by this device to avoid damage to the catalytic converter as a result caused by overload.

Bei der Brennkraftmaschine mit der bekannten Abgas-TTJrbo-Aufladung saugt die Brennkraftmaschine über den Luftfilter und den Gemischregler 2 über die Saugleitung 3 Frischluft an, die über den Abgas-Turbolader 5 in die Druckleitung 6, das Drosselklappengehäuse 7, zu dem Luftverteiler 8 und somit der Brennkraftmaschine 9 zugeführt wird. Der Abgasstrom der Brennkraftmaschine 9 wird durch eine Abgassammelleitung 10 über die Abgasturbine 11 des Abgas-Turboladers und den Schalldämpfer 12 ins Freie geleitet. Durch den Abgasstrom wird die Abgasturbine 11 angetrieben, die wiederum das Ladegebläse 4 antreibt, das die Frischluft unter überdruck der Brennkraftmaschine 9 zuführt. Ein in die Abgassammelleitung 10 eingesetztes Regelventil 13 regelt den Ladedruck des Ladegebläses 4, indem über eine Steuerleitung 14 durch den Ladeüberdruck das Regelventil 13 geöffnet und der Abgasstrom über die Abgasnebenleitung 15 unter Umgehung der Abgasturbine 11 direkt zum Schalldämpfer 12 gelangt. Zur Aufrechterhaltung der Ladegebläsedrehzahl, z.B. bei Schiebebetrieb des Fahrzeuges bzw. um ein schnelles Ansprechen der Brennkraftmaschine 9 beim Beschleunigen zu erhalten, ist zwischen der Saugleitung 3 und der Druckleitung 6 eine Verbindungsleitung mit einem Abblaseventil angeordnet. Das Abblaseventil 16 wird über eine weitere Steuerleitung 17 betätigt, in welcher bei geschlossener Drosselklappe durch Unterdruck das Abblaseventil 16 geöffnet wird, so daß ein Kreislauf des Frischluftstromes um das Ladegebläse 4 entsteht, wodurch die Ladegebläsedrehzahl aufrecht erhalten bleibt. In dem Ausführungsbeispiel der Figuren 1 und 2 ist in der Abgasleitung 10 vor der Abgasturbine 11 ein Katalysator und in dem Ausführungsbeispiel der Figur 3 ist in der der Abgasleitung im wesentlichen entsprechenden Abgasleitung 18 hinter der Abgasturbine 11 ein Katalysator 19 angeordnet.In the internal combustion engine with the known exhaust gas TTJrbo charging The internal combustion engine sucks in fresh air via the air filter and the mixture regulator 2 via the suction line 3 on, which via the exhaust gas turbocharger 5 into the pressure line 6, the throttle valve housing 7, to the air distributor 8 and thus the internal combustion engine 9 is supplied. The exhaust gas flow from the internal combustion engine 9 is conveyed through an exhaust manifold 10 Via the exhaust gas turbine 11 of the exhaust gas turbocharger and the Silencer 12 directed into the open. Through the exhaust gas flow is the exhaust gas turbine 11 is driven, which in turn drives the charging fan 4, which feeds the fresh air under overpressure of the internal combustion engine 9 feeds. One inserted into the exhaust manifold 10 Control valve 13 regulates the charge pressure of the charge blower 4 by the Control valve 13 is opened and the exhaust gas flow via the exhaust gas secondary line 15, bypassing the exhaust gas turbine 11, directly to the muffler 12 arrives. To maintain the supercharger speed, e.g. when the vehicle is coasting or when the internal combustion engine 9 responds quickly when accelerating To obtain a connection line with a relief valve is between the suction line 3 and the pressure line 6 arranged. The relief valve 16 is via a further control line 17 actuated, in which with the throttle valve closed the relief valve 16 is opened by negative pressure, so that a circuit of the fresh air flow around the charge blower 4 is created, whereby the charge blower speed is maintained. In the embodiment of Figures 1 and 2 is in the exhaust pipe 10 in front of the exhaust gas turbine 11 is a catalytic converter and in the exemplary embodiment in FIG. 3 it is in the exhaust gas line A catalytic converter 19 is arranged downstream of the exhaust gas turbine 11, essentially corresponding to the exhaust gas line 18.
Die Funktion der Erfindung ist folgende:The function of the invention is as follows:
Nach dem Anlassen der Brennkraftmaschine 9 wird durch deren Abgase die Abgasturbine 11 und somit das Ladegebläse 4 angetrieben. Aufgrund des noch relativ geringen Ladedruckes ist das Regelventil 13 geschlossen und sämtliche Abgase werden von dem Katalysator 17 bzw. 19 geleitet. Wird die DrosselklappeAfter starting the internal combustion engine 9 is through the Exhaust gases, the exhaust turbine 11 and thus the charging fan 4 are driven. Due to the still relatively low boost pressure is the control valve 13 is closed and all exhaust gases are passed from the catalytic converter 17 and 19, respectively. Will the throttle

der Brennkraftmaschine 9 weiter geöffnet, steigt der Ladedruck des Ladegebläses 4 an. Erreicht dieser einen vorbestimmten Wert, so öffnet das Regelventil 13 die Abgasnebenleitung 15 und ein Teil der Abgase wird über die Abgasnebenleitung 15 unter Umgehung des Katalysators 17 bzw. 19 direkt bzw. über den Schalldämpfer 12 in die Atmosphäre abgeblasen. Somit wird eine thermische überbelastung des Katalysators 17 bzw. 19 mit Sicherheit vermieden. Fällt der Ladedruck wieder ab, schließt das Regelventil 13 die Abgasnebenleitung 15 und die gesamten Abgase werden wieder über den Katalysator 17 bzw. 19 geleitet.the internal combustion engine 9 is opened further, the boost pressure increases of the charge blower 4. If this reaches a predetermined one Value, the control valve 13 opens the exhaust gas secondary line 15 and part of the exhaust gases is via the exhaust gas secondary line 15, bypassing the catalytic converter 17 or 19, directly or via the muffler 12 into the atmosphere blown off. Thermal overloading of the catalytic converter 17 or 19 is thus reliably avoided. The falls Boost pressure decreases again, the control valve 13 closes the secondary exhaust line 15 and all of the exhaust gases are over again the catalyst 17 or 19 passed.
