Abstract

For an air-compressing internal combustion engine with fuel injection, especially a diesel engine with direct fuel injection with a controllable/adjustable exhaust gas recirculation device, it is proposed, in order to reduce the influence of long-lasting deposits from externally recycled exhaust gas in the intake lines, that separate intake lines provided for each combustion chamber comprise a swirl duct and a charging duct of essentially swirl-free design, the charging duct being controllable by means of a throttle element and the exhaust gas recirculation device having a feedline opening into the charging duct downstream of the throttle element.

Description

Die Erfindung bezieht sich auf eine nach dem Oberbegriff des Patentanspruches 1 gestaltete luftverdichtende Ein­ spritz-Brennkraftmaschine.The invention relates to one according to the preamble of claim 1 designed air-compressing A injection internal combustion engine.

Die bei Dieselmotoren bekannte, externe Abgasrückführung ergibt in den Ansaugleitungen dauerhafte Ablagerungen, die das auf Leistung, Verbrauch und Abgasqualität opti­ mierte Einströmen der Ladung nachteilig beeinflussen.The external exhaust gas recirculation known from diesel engines results in permanent deposits in the intake lines, that opti for performance, consumption and exhaust gas quality adversely affect the inflow of the cargo.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungs­ gemäße Einspritz-Brennkraftmaschine so weiter zu bilden, daß der Einfluß dauerhafter Ablagerungen auf den Betrieb der Maschine wesentlich reduziert ist.The invention has for its object a genus to further develop the appropriate injection internal combustion engine, that the influence of permanent deposits on the operation the machine is significantly reduced.

Diese Aufgabe löst die Erfindung gemäß den Kennzeichen­ merkmalen des Patentanspruches 1 dadurch, daß je Brenn­ raum vorgesehene, gesonderte Ansaugleitungen einen Drall­ kanal und einen im wesentlichen drallfrei gestalteten Füllkanal umfassen, wobei der Füllkanal mittels eines Drosselorgans steuerbar ist und die Abgasrückführeinrich­ tung eine in den Füllkanal stromab des Drosselorgans mün­ dende Zuleitung aufweist. The invention achieves this object according to the characteristics Features of claim 1 characterized in that each Brenn space provided, separate suction lines a twist channel and a substantially swirl-free Filling channel include, the filling channel by means of a Throttle body is controllable and the exhaust gas recirculation device tion into the filling channel downstream of the throttling device end of the supply line.  

Der Vorteil der Erfindung ist, daß die Abgasrückführung auf eine der Ansaugleitungen je Brennraum beschränkt ist, die im Betriebsbereich der Dieselmaschine mit Abgasrück­ führung an der für Leistung, Verbrauch und Abgasqualität wesentlichen Dralleinströmung nur geringen Anteil hat. Mit der erfindungsgemäßen Rückführung von Abgas aus­ schließlich in eine als Füllkanal dienende Ansaugleitung bleibt die als Drallkanal gemischbildungsbestimmende An­ saugleitung über die gesamte Betriebsdauer frei von Abla­ gerungen aus der Abgasrückführung, wodurch in vorteilhaf­ ter Weise gleichbleibende Werte für Leistung, Verbrauch und Emissionen erzielt werden.The advantage of the invention is that the exhaust gas recirculation is limited to one of the intake lines per combustion chamber, those in the operating area of the diesel engine with exhaust gas return leadership in performance, consumption and exhaust gas quality essential swirl flow has only a small proportion. With the recirculation of exhaust gas according to the invention finally into a suction line serving as a filling channel remains the determining factor as a swirl channel Suction line free of waste over the entire operating time wrestled from the exhaust gas recirculation, which is advantageous consistent values for performance, consumption and emissions are achieved.

Eine in Ausgestaltung der Erfindung vorgeschlagene funk­ tionelle Koppelung der Steuerungen von Abgasrückführein­ richtung und Füllkanal ermöglicht es ferner in vorteil­ hafter Weise, die Abgasrückführrate in weiten Grenzen be­ liebig zu verändern, wobei der gesamte oder überwiegende Luftanteil über den gemischbildungsbestimmenden Drall­ kanal dem Brennraum zugeführt ist. Erreicht ist damit eine größere Ladung je Arbeitsspiel im Brennraum.A radio proposed in an embodiment of the invention tional coupling of the exhaust gas recirculation controls direction and filling channel also allows it to advantage way, the exhaust gas recirculation rate be within wide limits change as you please, the whole or predominant Air fraction over the swirl that determines the mixture formation channel is fed to the combustion chamber. This is achieved a larger charge per work cycle in the combustion chamber.

Um bei einem Lastpunktwechsel einer mehrzylindrigen Ma­ schine die Einflüsse der in den Füllkanälen stromab der geschlossenen Drosselorgane gegebenen Toträume auf die Betriebsweise der Dieselmaschine zu reduzieren, stehen die Füllkanäle über eine Rohr-Leitung miteinander in Ver­ bindung. Erreicht ist damit eine Vergleichmäßigung der Inhalte der Toträume an Luft- und Abgasen, wodurch das Instationärverhalten der Maschine hinsichtlich Leistung und Rauch verbessert ist.In order to change a multi-cylinder Ma seem the influences of the filling channels downstream of the closed throttle bodies given dead spaces on the To reduce the operating mode of the diesel engine the filling channels via a pipe line with each other in ver binding. An equalization of the Contents of the dead spaces in air and exhaust gases, which means that Transient behavior of the machine in terms of performance and smoke is improved.

Zur gleichmäßigen Verteilung des extern rückgeführten Ab­ gases im Brennraum wird ferner vorgeschlagen, daß der Füllkanal in Richtung der Drallströmung im Brennraum der Mündung des Drallkanals benachbart in den Brennraum mün­ det.For even distribution of the externally returned Ab gases in the combustion chamber is also proposed that the Filling channel in the direction of the swirl flow in the combustion chamber  Mouth of the swirl channel adjacent to the combustion chamber det.

Ein geringer Platzbedarf bzw. Einbauraum für eine Ansaug­ anlage einer erfindungsgemäß gestalteten Dieselmaschine ergibt sich mit in einem gemeinsamen Luftsammler münden­ den Ansaugleitungen. Es können aber bei einer insbeson­ dere mehrzylindrigen Dieselmaschine den Drallkanälen und den Füllkanälen auch jeweils gesonderte Luftsammler zuge­ ordnet sein. In diesem Fall kann eine die Toträume der Füllkanäle gesondert verbindende Leitung entfallen.A small space requirement or installation space for an intake System of a diesel engine designed according to the invention results in having a common air collector the suction pipes. But it can in particular their multi-cylinder diesel engine the swirl channels and the air ducts also each have separate air collectors to be in order. In this case, the dead spaces of the There is no need for a separate connecting line for filling channels.

Die Erfindung ist anhand eines in der Zeichnung schema­ tisch dargestellten Beispiels einer Dieselmaschine be­ schrieben. Es zeigtThe invention is based on a schematic in the drawing table shown example of a diesel engine be wrote. It shows

Fig. 1 in einen Brennraum eines Zylinders mündende Ansaugleitungen, und Fig. 1 in a combustion chamber of a cylinder opening intake lines, and

Fig. 2 ein Lastdiagramm mit zugeordnetem Abgasrück­ führ-Betrieb. Fig. 2 is a load diagram with associated exhaust gas recirculation operation.

Eine abschnittsweise gezeigte, insbesondere direkt ein­ spritzende Dieselmaschine 1 weist einen Zylinder 2 auf, dessen Brennraum 3 mit zwei gesonderten Ansaugleitungen 4 und 5 einer Ansauganlage 6 in Verbindung steht. Die An­ saugleitung 4 weist in ihrer Mündung 7 in den Brennraum 3 eine Dralleinrichtung 8 auf und dient somit als gemisch­ bildungsbestimmender Drallkanal 9. Die andere Ansauglei­ tung 5 ist dagegen in ihrer Mündung 10 drallfrei gestal­ tet und dient als Füllkanal 11.A diesel engine 1 shown in sections, in particular directly spraying, has a cylinder 2 , the combustion chamber 3 of which is connected to two separate intake lines 4 and 5 of an intake system 6 . The suction line 4 has in its mouth 7 in the combustion chamber 3 a swirl device 8 and thus serves as a mix-forming swirl channel 9th The other Ansauglei device 5 , on the other hand, is designed in a swirl-free manner in its mouth 10 and serves as a filling channel 11 .

Der vom Drallkanal 9 getrennt verlaufende Füllkanal 11 ist im stromaufseitigen Endbereich mittels eines Drossel­ organs 12 steuerbar. Stromab dieses Drosselorgans 12 mün­ det in den Füllkanal 11 eine Zuleitung 13 einer nicht ge­ zeigten Abgasrückführeinrichtung der Dieselmaschine 1. Die Zuleitung 13 ist mit einem Steuerventil 14 ausgerü­ stet. Für einen Abgasrückführ-Betrieb, dessen Bereich 15 über der Drehzahl der Dieselmaschine 1 aus Fig. 2 er­ sichtlich ist, sind das Steuerventil 14 der Zuleitung 13 und das Drosselorgan 12 des Füllkanals 11 funktionell miteinander verknüpft bzw. gekoppelt. Die beispielsweise mechanische oder vorzugsweise über ein Kennfeld bewirkte Koppelung wird bei nicht benötigter Abgasrückführung auf­ gehoben, so daß über den im Querschnitt mit dem Drossel­ organ 12 steuerbaren Füllkanal 11 zusätzliche Ladung in den Brennraum 3 einführbar ist.The filling channel 11 , which runs separately from the swirl channel 9 , can be controlled in the upstream end region by means of a throttle element 12 . Downstream of this throttle element 12, a feed line 13 of an exhaust gas recirculation device (not shown) of the diesel engine 1 is fed into the filling channel 11 . The feed line 13 is equipped with a control valve 14 . For an exhaust gas recirculation operation, the area 15 of which is visible over the speed of the diesel engine 1 from FIG. 2, the control valve 14 of the feed line 13 and the throttle element 12 of the filling channel 11 are functionally linked or coupled to one another. The coupling, for example mechanical or preferably effected via a characteristic map, is lifted when exhaust gas recirculation is not required, so that additional charge can be introduced into the combustion chamber 3 via the filling channel 11 which can be controlled in cross section with the throttle organ 12 .

Mit dem Anschluß der steuerbaren Abgasrückführeinrichtung über die Zuleitung 13 an den steuerbaren Füllkanal 11 bleibt der für jeden aus dem Diagramm der Fig. 2 erkenn­ baren Lastpunkt der Ladungszufuhr dienende Drallkanal 9 als gemischbildungsbestimmende Ansaugleitung 4 frei von extern rückgeführten, Ablagerungen bewirkenden Abgasen.To the terminal of the controllable exhaust gas recirculation device via the feed line 13 to the controllable filling channel 11 of the charge supply serving swirl duct 9 recirculated for each of the diagram of Fig. 2 Detection cash load point as mixture formation determining intake duct 4 free of externally deposits causing exhaust gases remains.

Um bei instationärem Betrieb einer mehrzylindrigen Die­ selmaschine 1 die Einflüsse der in den Füllkanälen 11 stromab der geschlossenen Drosselorgane 12 bis zu den Ka­ nalmündungen 10 gegebenen Toträume auf die Betriebsweise der Dieselmaschine 1 zu reduzieren, stehen die Füllkanäle 11 über eine Rohrleitung 16 miteinander in Verbindung.To Selma machine 1 to reduce downstream in the filling channels 11 of the closed throttle bodies 12 to the Ka nalmündungen 10 given dead spaces to the operation of the diesel engine 1 at unsteady operation of a multi-cylinder, the influences of stand the filling channels 11 via a pipe 16 with each other.

Eine gleichmäßige Verteilung des extern rückgeführten Ab­ gases in jedem Brennraum 3 ist dadurch erreicht, daß die Mündung 10 des Füllkanals 11 in Richtung der Drallströ­ mung gemäß Pfeil A im Brennraum 3 der Mündung 7 des Drallkanals 9 benachbart ist.A uniform distribution of the externally recirculated gas from each combustion chamber 3 is achieved in that the mouth 10 of the filling channel 11 in the direction of the swirl flow according to arrow A in the combustion chamber 3 of the mouth 7 of the swirl channel 9 is adjacent.

Stromauf des Drosselorgans 12 des Füllkanals 11 mündet dieser mit dem Drallkanal 9 in einen gemeinsamen Luftsammler 17. Upstream of the throttle element 12 of the filling duct 11 , the latter opens with the swirl duct 9 into a common air collector 17 .

Im Rahmen der Erfindung ist es auch denkbar, daß die Drallkanäle und die Füllkanäle einer mehrzylindrigen, luftverdichtenden Einspritz-Brennkraftmaschine jeweils mit gesonderten Luftsammlern in Verbindung stehen.In the context of the invention it is also conceivable that the Swirl channels and the filling channels of a multi-cylinder, air-compressing injection internal combustion engine each communicate with separate air collectors.
