Das technische Gebiet, auf das sich die Erfindung bezieht, betrifft im weitesten Sinne die Kraftfahrzeugtechnik und im engeren Sinne Brennkraftmaschinen, bei denen eine Abgasrückführung in das Luftzufuhrsystem der Brennkraftmaschine erfolgt.The technical field to which the invention relates concerns in the broadest sense the automotive technology and, in the narrower sense, internal combustion engines in which an exhaust gas recirculation takes place in the air supply system of the internal combustion engine.

Stand der TechnikState of the art

Derartige Abgasrückführsysteme für Brennkraftmaschinen sowie die zugehörigen Abgasrückführ-Absperrorgane sind seit geraumer Zeit bekannt und bedürfen hier keiner besonderen Erläuterung. Im allgemeinen dient diese Abgasrückführung der Verbesserung der Emissionswerte, des Verbrauchs etc.Such exhaust gas recirculation systems for internal combustion engines and the associated exhaust gas recirculation shut-off valves have been known for some time and require no particular explanation here. In general, this exhaust gas recirculation serves to improve the emission values, consumption, etc.

Eine Anordnung nach dem Oberbegriff des Anspruchs 1 ist aus der DE 197 33 964 A1 bekannt und weist im wesentlichen eine Kühleinrichtung, die von den Abgasen durchströmt wird, eine Bypass-Leitung, welche die Kühleinrichtung umgeht, sowie eine Ventilanordnung auf, mittels derer die Abgase wahlweise durch die Kühleinrichtung oder die Bypass-Leitung geführt werden.An arrangement according to the preamble of claim 1 is known from DE 197 33 964 A1 and comprises essentially a cooling device, which is flowed through by the exhaust gases, a bypass line, which bypasses the cooling device, and a valve arrangement, by means of which the exhaust gases are selectively guided by the cooling device or the bypass line.

Die nachveröffentlichte EP 0 987 427 A sowie die Druckschriften US 4,147,141 A und DE 197 33 964 A offenbaren ebenfalls Abgasrückführsysteme mit Bypass-Leitungen.The post-published EP 0 987 427 A as well as the pamphlets US 4,147,141 A and DE 197 33 964 A also disclose exhaust gas recirculation systems with bypass lines.

Darstellung der ErfindungPresentation of the invention

Das technische Problem (Aufgabe) der Erfindung besteht in einer weiteren Verbesserung der Emissionswerte sowie des Kraftstoffverbrauchs einer Brennkraftmaschine im Zusammenhang mit einer Abgasrückführung sowie einer konstruktiven Vereinfachung des Abgasrückführsystems.The technical problem (object) of the invention consists in a further improvement of the emission values and the fuel consumption of an internal combustion engine in connection with exhaust gas recirculation and a constructive simplification of the exhaust gas recirculation system.

Diese Aufgabe wird durch das Abgasrückführsystem gemäß dem Anspruch 1 gelöst.This object is achieved by the exhaust gas recirculation system according to claim 1.

Insbesondere ist eine Bypass-Leitung vorhanden, die eine Kühleinrichtung für das rückgeführte Abgas umgeht, wobei vor der Kühleinrichtung eine Weiche angeordnet ist, deren Einlaß mit einer Abgasrückführleitung verbunden ist. Diese Weiche weist zwei Durchlässe auf, von denen einer mit der Kühleinrichtung und der andere mit der Bypass-Leitung verbunden ist. Dies ist derart vorgesehen, daß die Abgase alternativ durch die Kühleinrichtung oder die Bypass-Leitung strömbar sind. Die Weiche ist integraler Bestandteil der Kühleinrichtung und besteht aus genau einem Bypass-Ventil oder genau einer Bypass-Klappe besteht, das bzw. die in der Verzweigung vor Kühleinrichtung und Bypass-Leitung angeordnet ist und in einer ersten Betriebsstellung die Kühleinrichtung und in einer zweiten Betriebsstellung die Bypass-Leitung verschließt.In particular, a bypass line is provided, which bypasses a cooling device for the recirculated exhaust gas, wherein before the cooling device, a switch is arranged, whose inlet is connected to an exhaust gas recirculation line. This switch has two passages, one of which is connected to the cooling device and the other to the bypass line. This is provided in such a way that the exhaust gases can alternatively be flowed through the cooling device or the bypass line. The switch is an integral part of the cooling device and consists of exactly one bypass valve or exactly one bypass flap, which is arranged in the branch before the cooling device and bypass line and in a first operating position, the cooling device and in a second operating position closes the bypass line.

Der Erfindung liegt die Erkenntnis zugrunde, daß die Rückführung der Abgase nicht jederzeit zu günstigen Ergebnissen führt. Insbesondere wurde erkannt, daß in der Warmlaufphase die Temperatur der Abgase zu niedrig ist, um den angestrebten Erfolg zu erzielen. Erfindungsgemäß ist daher vor der Kühleinrichtung eine Weiche vorgesehen, damit in der Warmlaufphase das Abgas um die Kühleinrichtung herum geleitet werden, also ungekühlt in das Luftzufuhrsystem gelangen kann, wodurch in der Warmlaufphase bessere Emissionswerte und ein günstigerer Kraftstoffverbrauch erzielt werden können. Wenn die Abgase dann im Normalbetrieb eine Temperatur haben, bei der eine Kühlung zu besseren Ergebnissen führen würde, wird die Weiche umgeschaltet, so daß die Abgase den Kühler durchströmen und dann entsprechend gekühlt in das Luftzufuhrsystem gelangen.The invention is based on the finding that the recirculation of the exhaust gases does not always lead to favorable results. In particular, it was recognized that in the warm-up phase, the temperature of the exhaust gases is too low to achieve the desired result. According to the invention, therefore, a switch is provided in front of the cooling device, so that the exhaust gas can be conducted around the cooling device in the warm-up phase, ie can reach the air supply system without cooling, whereby better emission values and more favorable fuel consumption can be achieved in the warm-up phase. If the exhaust gases are then in normal operation at a temperature at which cooling would lead to better results, the switch is switched so that the exhaust gases flow through the radiator and then get cooled accordingly in the air supply system.

Eine vorteilhafte Ausgestaltung ergibt sich aus dem Unteranspruch.An advantageous embodiment results from the dependent claim.

Fig. 1 zeigt ein Abgasrückführsystem mit der schematischen Darstellung einer Vierzylinder-Brennkraftmaschine 1 mit einem Abgasleitungssystem 2 und einem Luftzuführ- bzw. Luftansaugsystem 3, welches ein Luftströmungsmeßgerät 4 und eine Drossel 5 aufweist. Wesentliches Bestandteil des Abgasrückführsystems ist eine Abgasrückführleitung 6 mit einem Abgasrückführventil 7 und einem Kühler 10. Die Abgasrückführleitung 6 mündet in das Luftzuführsystem 3, wie dies der Fig. 1 zu entnehmen ist. Gesteuert wird die Abgasrückführung über das Abgasrückführventil 7. Eine weitere Beschreibung des Prinzips ist hier nicht notwendig, da dies dem Fachmann hinlänglich bekannt ist. Fig. 1 shows an exhaust gas recirculation system with the schematic representation of a four-cylinder internal combustion engine 1 with an exhaust pipe system 2 and an air intake 3, which comprises a Luftströmungsmeßgerät 4 and a throttle 5. An essential part of the exhaust gas recirculation system is an exhaust gas recirculation line 6 with an exhaust gas recirculation valve 7 and a radiator 10. The exhaust gas recirculation line 6 opens into the air supply system 3, as the Fig. 1 can be seen. The exhaust gas recirculation is controlled via the exhaust gas recirculation valve 7. A further description of the principle is not necessary here, since this is well known to the person skilled in the art.

Eine den Kühler 10 umgehende Bypass-Leitung 17, die durch ein Bypass-Ventil 18 gesteuert ist, ist in Fig. 1 als vom Kühler 10 räumlich getrenntes Ventil dargestellt.A bypass passage 17 bypassing the radiator 10, which is controlled by a bypass valve 18, is in FIG Fig. 1 shown as spatially separated from the radiator 10 valve.

Der in Fig. 2 bzw. Fig. 3 dargestellte Kühler 10 weist einen Einlaß 11 und einen Auslaß 12 auf, jeweils für die Zuführung und die Abführung des Kühlmittels. Außerdem ist ein Einlaß 13 vorgesehen für die Zuführung des Abgases entsprechend einem Pfeil 14. Der Kühler weist weiterhin einen Auslaß 15 auf, aus dem entsprechend dem Pfeil 16 entweder gekühltes oder nicht gekühltes Abgas abgegeben wird. Den Kühler 10 umgeht die Bypass-Leitung 17. Im Einlaßbereich des Kühlers gemäß der Ausführungsform der Fig. 2 ist integriert in den Kühler ein Ventil 18 vorgesehen. Bei dem Ausführungsbeispiel der Fig. 3 ist eine Klappe 19 vorgesehen. Dieses Ventil 18 bzw. die Klappe 19 bilden als Bypass-Organe eine Weiche, durch die bei entsprechender Einstellung das Abgas entweder durch den Kühler strömt oder durch die Bypass-Leitung 17 geleitet wird. Das Ventil 18 bzw. die Klappe 19 sind mit einem Steuerorgan 20 verbunden. In diesem Steuerorgan drückt im Normalbetrieb eine Feder 21 das Ventil 18 gemäß Fig. 2 in die mit ausgezogenen Linien dargestellte Normalbetriebsstellung, in der das Abgas durch den Kühler geleitet wird. In Fig. 3 ist die entsprechende Stellung der Klappe 19 ebenfalls in ausgezogenen Linien dargestellt. In der gestrichelten Betriebsstellung des Ventils 18 und der Klappe 19 gelangt das in den Einlaß 13 strömende Abgas in die Bypass-Leitung 17, umgeht also den Kühler 10 und gelangt ungekühlt in den Auslaß 15.The in Fig. 2 respectively. Fig. 3 shown cooler 10 has an inlet 11 and an outlet 12, respectively for the supply and the discharge of the coolant. In addition, an inlet 13 is provided for the supply of the exhaust gas according to an arrow 14. The radiator further has an outlet 15, from which according to the arrow 16 either cooled or not cooled exhaust gas is discharged. The cooler 10 bypasses the bypass line 17. In the inlet region of the radiator according to the embodiment of the Fig. 2 is integrated in the cooler, a valve 18 is provided. In the embodiment of the Fig. 3 a flap 19 is provided. This valve 18 and the flap 19 form as bypass organs a switch, through which the exhaust gas either flows through the radiator with an appropriate setting or is passed through the bypass line 17. The valve 18 and the flap 19 are connected to a control member 20. In this control member presses a spring 21, the valve 18 in accordance with normal operation Fig. 2 in the normal operating position shown in solid lines, in which the exhaust gas is passed through the radiator. In Fig. 3 the corresponding position of the flap 19 is also shown in solid lines. In the dashed operating position of the valve 18 and the flap 19, the exhaust gas flowing into the inlet 13 passes into the bypass line 17, thus bypasses the radiator 10 and passes uncooled into the outlet 15th

Gesteuert wird das Ventil 18 bzw. die Klappe 19 als Weiche durch ein in Fig. 2 und 3 nicht, aber in Fig. 1 dargestelltes elektronisches Steuersystem 8. Dies erfolgt entweder abhängig von der Temperatur des rückgeführten Abgases oder lastabhängig, drehzahlabhängig oder durch andere Motorparameter, die durch einen Sensor erfaßt werden. Wenn in der Warmlaufphase die Abgase eine relativ niedrige Temperatur aufweisen, werden die Abgase durch die Bypass-Leitung 17 geleitet und gelangen ungekühlt in das Luftzufuhrsystem der Brennkraftmaschine. Wenn die Brennkraftmaschine warmgelaufen ist, durchströmen die Abgase bei entsprechender Stellung der Weiche den Kühler und gelangen gezielt gekühlt in das Luftzufuhrsystem.The valve 18 or the flap 19 is controlled as a switch by a in FIGS. 2 and 3 not, but in Fig. 1 This is done either depending on the temperature of the recirculated exhaust gas or load-dependent, speed-dependent or by other engine parameters that are detected by a sensor. When in the warm-up phase, the exhaust gases have a relatively low temperature, the exhaust gases are passed through the bypass line 17 and arrive uncooled in the air supply system of the internal combustion engine. When the internal combustion engine has warmed up, the exhaust gases flow through the radiator in the appropriate position of the switch and get targeted cooled in the air supply system.

Die Steuerung des Ventils 18 bzw. der Klappe 19 in die gestrichelt dargestellte Stellung für die Warmlaufphase erfolgt gegen die Kraft der Feder 21 durch Überdruck oder Unterdruck, bevorzugt durch Unterdruck.The control of the valve 18 and the flap 19 in the position shown in dashed lines for the warm-up phase takes place against the force of the spring 21 by overpressure or negative pressure, preferably by negative pressure.
