Description

Otto-Motor mit einem Turbolader und einer Entgiftungsanlage Die Erfindung bezieht sich auf einen Otto-Motor mit einem Turbolader und einer vor oder hinter diesem angeordneten Entgiftungsanlage (Katalysator oder Reaktor) sowie mit einer vom Notor über eine Kupplung angetriebene Luftpumpe, die der deutschen Patentanmeldung P 20 27 883.5 gemäß Einblaseluft in die Abgasrohre liefert.Otto engine with a turbocharger and a detoxification system The invention refers to a gasoline engine with a turbocharger and one in front or behind this arranged detoxification system (catalyst or reactor) as well as with a Air pump driven by the Notor via a clutch, that of the German patent application P 20 27 883.5 delivers according to air injection into the exhaust pipes.

Aufgabe der Erfindung ist es, die Entgiftungsanlage und den Turbolader vor zu hohen Drücken oder zu hohen Temperaturen zu bewahren.The object of the invention is the detoxification system and the turbocharger to protect against too high pressures or too high temperatures.

Diese Aufgabe wird durch die Erfindung dadurch gelöst1 daß der Aufladedruck durch ein zwischen Auslaßkanal und Entgiftungsanlage angeordnetes Ventil regelbar ist, das die durch eine Umgehungsleitung um die Entgiftungsanlage und den Turbolader strömende Abgasmenge durch den Saugrohr~ druck steuert. Dabei kann däs Ventil von einem vorbestimmten Saugrohr-Absolutdruclc ab einen Teil des Abgasstromes an der Entgiftungsanlage vorbeiführen, dessen Menge sich bei höheren Lasten und Drehzahlen steigert. Weiterhin kann das Ventil bei Überschreiten eines noch höher liegenden Grenzpunktes für Last und Drehzahl ganz geöffnet werden, so daß das Abgas die Zntgiftungsanlage fast völlig umgeht.This object is achieved by the invention in that the boost pressure adjustable by a valve arranged between the outlet channel and the decontamination system is the one that goes through a bypass around the decontamination system and the turbocharger the amount of exhaust gas flowing through the intake manifold pressure. The valve can be from a predetermined intake manifold absolute pressure from a part of the exhaust gas flow at pass the detoxification system, the amount of which increases at higher loads and speeds increases. Furthermore, the valve can be located at an even higher level when it is exceeded The limit point for load and speed are fully opened, so that the exhaust gas enters the Zntgiftungsanlage almost completely bypasses.

Durch diese Ivlaßnahmen wird der Ladedruck des au£geladenen Otto-Motors durch abgasseitige Abblasung mit hilfe eines membrangesteuerten Ventils begrenzt und dieses Ventil andererseits noch dazu verwendet, um die abgeblasene Abgasmenge bei höheren Lasten und Drehzahlen nicht durch das Katalysatorbett und/oder den Reaktor zu führen und damit diese Entgiftungsanlagen zu entlasten. Des weiteren kann mit demselben Ventil das Katalysatorbett und/oder der Reaktor bei Zündaussetzung mittels eines Temperaturfühlers vor Überhitzung dadurch geschützt werden, daß das Abblaseventil ganz öffnet und somit die durch den Ivatalysator strömende Abgasmenge stark absinkt oder überhaupt kein Abgas mehr durch den Katalysator hindurchströmt.These measures reduce the boost pressure of the charged Otto engine limited by blow-off on the exhaust gas side with the aid of a diaphragm-controlled valve and this valve, on the other hand, is also used to control the amount of exhaust gas that is blown off at higher loads and speeds not through the catalyst bed and / or the reactor to lead and thus to relieve these detoxification systems. Furthermore, with the same valve, the catalyst bed and / or the reactor when ignited by means of a temperature sensor can be protected from overheating in that the relief valve opens completely and thus the amount of exhaust gas flowing through the catalytic converter drops sharply or no exhaust gas at all flows through the catalytic converter.

Der Grenzpunkt, von dem ab das Ventil umgeschaltet wird, kann in weiterer Ausgestaltung der Erfindung durch einen Thermostaten ermittelt werden, der die Temperatur des Abgases nach dem Katalysator und vor dem Turbolator nbtastet sowie über einen Meßwertaufnehnier einen entsprechenden Offnungsbefehl an den Steuermagneten des Abblaseventils gibt. Dabei kann der Meßwertaufnehmer zugleich einen Öffnungsbefehl an die Kupplung der Luftpumpe geben, so daß diese zur gleichen Zeit abgeschaltet wird.The limit point from which the valve is switched can be set in further Embodiment of the invention can be determined by a thermostat that the temperature of the exhaust gas after the catalytic converter and before the turbolator and via a Meßwertaufnehnier a corresponding opening command to the control magnet of the Relief valve there. The transducer can at the same time issue an opening command to the coupling of the air pump so that it is switched off at the same time will.

Die durch den die Temperatur des Abgases abtastenden Thermostaten über den tter,wertaufnelmter geöffneten Mittel, nämlich der Steuermagnet des Abblaseventils und die Kupplung können im übrigen so ausgebildet sein, daß sie auch, nachdem die Temperatur schon wieder abgesunken ist, solange geöffnet bleiben, bis sie von hand wieder geschlossen Der den. Durch diese weitere erfindungsgemäße Ausstattung wird eine Notschaltung dargeboten, die nur durch einen äußeren Eingriff rückgängig gen acht werden kann, so daß dadurch der Fahrzeugbenutzer auf den vorliegenden liotorschaden aufmerksam gemacht wird. Der gleiche Regeleingriff soll auch dazu benutzt werden, eine eventuell verwendete Luftpumpe durch Entkuppeln außer Betrieb zu setzen.- Diese Entkupplungseinrichtung ist so ausgebildet, daß beim Offnen des Abblaseventils eine Vorrichtung einrastet, die solange eingerastet bleibt, bis sie von liand wieder entriegelt wird. Diese Vorrichtung, die das Äbblaseventil geöffnet halt, kann zugleich auch die Kupplung der Luftpumpe geöffnet halten.The thermostat that senses the temperature of the exhaust gas about the killer, security office opened agent, namely the control magnet of the relief valve and the coupling can also be designed so that they even after the temperature has dropped again, stay open as long as until they are closed again by hand. By this further according to the invention Equipment is offered an emergency circuit, which can only be done by an external intervention can be reversed eight, so that thereby the vehicle user on the present liotor damage is made aware. The same control intervention should also be used can be used, a possibly used air pump out of order by uncoupling to set.- This uncoupling device is designed so that when the Relief valve engages a device that remains in place until it is unlocked again by liand. This device that opens the blow-off valve stop, can also keep the clutch of the air pump open at the same time.

Die Erfindung ist im folgenden anliand eines in der Zeichnung -dargestellten Ausführungsbeispiels, dem auch weitere Einzelheiten der Erfindung cntnommen werden können, näher erläutert.The invention is shown in the following anliand in the drawing Embodiment, which also cnttnn further details of the invention can, explained in more detail.

Die Zeichnung zeigt in schematischer Darstellung einen Zylinderblock 1 einer Sechszylinderbrennkraftmaschine, die nach dem Otto-Prinzip arbeitet. Die Abgase treten aus dem Auslaßventil in sechs abgasrohre 2 aus, die in den Katalysator 3 münden. An den Katalysator 3 schließt sich ein Abgasturbolader 4 an, von dem aus die- Abgase in das Abgasrohr 5 abgeleitet werden. Der Abgasturbolader 4 treibt einen Kompressor 6 an, der über ein Filter 7 und eine Drosselklaipe 8 angesaugte Luft lortlpril:liert und sie über die Leitung 9 sowie die Ladeluftlühler 1o dem SaugroI-ir 11 zuführt.The drawing shows a schematic representation of a cylinder block 1 of a six-cylinder internal combustion engine that works according to the Otto principle. the Exhaust gases exit the exhaust valve in six exhaust pipes 2 which lead into the catalytic converter 3 open. The catalytic converter 3 is followed by an exhaust gas turbocharger 4, from which the exhaust gases are diverted into the exhaust pipe 5. The exhaust gas turbocharger 4 drives one Compressor 6 on, the air sucked in via a filter 7 and a throttle valve 8 lortlpril: liert and she via line 9 and the charge air cooler 1o the suction tube 11 feeds.

Von der Kurbelwelle des Rotors wird iiber ein Vorgelege 12 und eine Magnetkupplung 13 eine Luftputiipe 14 angetrieben, die aus dem Freien Luft ansaugt und komprimierte Luft über die Leitung 15 als Einblaseluft den Abgasrohren 2 zuführt.A countershaft 12 and a Magnetic coupling 13 drives an Luftputiipe 14, which sucks in air from the open and compressed air is supplied to the exhaust pipes 2 via the line 15 as blowing air.

Die Abgasrohre 2 stehen mit einer Umgehungsleitung 16 in Verbindung durch die Abgase bei geöffneten Abblaseventil 17 um den I;atalysator 3 und den Abgasturbolader 4 herum und direkt dem Abgasrohr 5 zugeleitet werden können.The exhaust pipes 2 are connected to a bypass line 16 through the exhaust gases with the blow-off valve 17 open, around the analyzer 3 and the exhaust gas turbocharger 4 around and directly to the exhaust pipe 5 can be fed.

Das Abblaseventil 17 wird durch Unterdruck dadurch betätist, daß es über die Leitung 18 mit dem Saugrohr 11 verbunden ist. Das Abblaseventil 17 weist einen Steuermagnet 19 auf, der von einem Meßwertaufnehmer 21 geschaltet wird.The relief valve 17 is operated by negative pressure in that it is connected to the suction pipe 11 via the line 18. The relief valve 17 has a control magnet 19 which is switched by a transducer 21.

Der lleßwertaufnehmer 21 tastet ständig mit einem Thermoelement 22 die Temperatur der Abgase im Stutzen 23 des Abgasturboladers 4 ab. Wird bei höheren Lasten und Drehzahlen ein vorbestimmter Meßpunkt erreicht, dann gibt der Bießwertaufnehmer 21 an das Abblaseventil 17 über den Steuermagnet 19 den Befehl, das Abblaseventil ganz zu öffnen und somit den grör,ten Teil der Abgase um den Katalyse tor herum zu führen, wodurch dieser entlastet wird und somit seine Temperatur sinken kann. Wenn der Steuermagnet voll unter Strom steht und somit das Abblaseventil ganz geöffnet ist, rastet eine Vorrichtung ein, die auch bei wieder absinkender Temperatur eingerastet bleibt und nur von hand geöffnet werden kann. Gleichzeitig flient auch ein Steuerstrom in die Nagnetkupplung 13 der Luftpumpe 14.The measured value sensor 21 constantly scans with a thermocouple 22 the temperature of the exhaust gases in the connection 23 of the exhaust gas turbocharger 4. Will be at higher Loads and speeds reached a predetermined measuring point, then the bias value transducer gives 21 to the relief valve 17 via the control magnet 19 the command, the relief valve to open completely and thus most of the exhaust gases around the catalytic converter to lead, whereby this is relieved and thus its temperature can drop. When the control magnet is fully energized and the relief valve is fully open a device engages, which engages when the temperature drops again remains and can only be opened by hand. At the same time also flies a Control current in the magnetic coupling 13 of the air pump 14.

Dadurch wird diese vom Motor abgetrennt und fördert nicht mehr.As a result, it is separated from the engine and no longer feeds.
