Durch kontrollierte Einleitung von Verbrennungsgasen einer Brennkraftmaschine in deren Brennräume werden während der Kraftstoffverbrennung Stickoxide -NOx-, die die Brennkraftmaschine emittiert, reduziert. Bei Verbrennung eines Kraftstoff-Luft-Gemischs nimmt die Bildung von Stickoxiden mit Anstieg der Verbrennungstemperatur überproportional zu. Durch Rückführung eines Teils der Abgase wird die Verbrennungstemperatur gesenkt und Stickoxide verringert.By controlled introduction of combustion gases of an internal combustion engine in the combustion chambers nitrogen oxides -NOx-, which emits the internal combustion engine, are reduced during fuel combustion. When burning a fuel-air mixture, the formation of nitrogen oxides increases disproportionately with an increase in the combustion temperature. By recycling some of the exhaust gases, the combustion temperature is lowered and nitrogen oxides are reduced.

Geschickt gelöst ist, dass das Abgasrückführungssystem über die mit der Abgasleitung verbundene Rohrabzweigung verfügt, die unter Zwischenschaltung des Steuerelements an die Abgasrückführungsleitung angeschlossen ist. Dabei ist hervorzuheben, dass die Abgasrückführungsleitung sich einerseits mit einem ersten Zuführungsleitungsanschnitt außerhalb und andererseits mit einem zweiten Zuführungsleitungsabschnitt im Innenraum eines Sauganlagenbehälters der Sauganlage erstreckt. Unterstützend ist in diesem Zusammenhang, dass mittels des zweiten Zuführungsleitungsabschnitts der Abgasstrom in den Sauganlagenbehälter zur gezielten Vermischung der Abgase mit dem im Sauganlagenbehälter enthaltenen Luftvolumen gefördert wird.The advantages achieved by the invention are to be seen in the fact that the exhaust gas recirculation system is an exemplary construction that can be integrated with simple means in an internal combustion engine. And thanks to this construction, the exhaust gas recirculation system has an excellent function with regard to the reduction of nitrogen oxides. Cleverly solved is that the exhaust gas recirculation system has connected to the exhaust pipe pipe branch, which is connected with the interposition of the control element to the exhaust gas recirculation line. It should be emphasized that the exhaust gas recirculation line extends on the one hand with a first Zuführungsleitungsanschnitt outside and on the other hand with a second supply line section in the interior of a Sauganlagenbehälters the suction system. It is aiding in this context that the exhaust gas flow into the intake system container for targeted mixing of the exhaust gases with the air volume contained in the intake system container is conveyed by means of the second supply line section.
Wirkungsvoll ist das Steuerelement, wenn es die Drosselvorrichtung aufweist, über die ein kalibrierter Abgasstrom in den Innenraum des Sauganlagenbehälters gelangt. Für diese Lösung ist funktionsgerecht, wenn die Abgasturboladereinrichtung in der Weise ausgebildet ist, dass im gesamten Kennfeldbereich der Brennkraftmaschine der Eintrittsdruck in die Abgasturbine größer ist als der Druck im Sauganlagenbehälter. Beispielgebend ist auch, dass das Steuerelement als pulsweitenmoduliertes Schaltventil ausgebildet ist, über das kennfeldgesteuert abgestimmte Abgasmengen Last und Drehzahl geregelt dem Sauganlagenbehälter zugeführt werden. Ein sinnreiches Steuerelement ist ferner, wenn es durch ein Auf- und Zu-Funktionen aufweisendes elektrisches Schaltventil gebildet wird, das Abgasmengen kennfeld- bzw. kennlinienabhängig entlang einer Kennlinie eines Antriebssystems freigibt.The control element is effective if it has the throttle device, via which a calibrated exhaust gas flow reaches the interior of the suction system container. For this solution is functional, if the exhaust gas turbocharger device is designed in such a way that in the entire map range of the internal combustion engine, the inlet pressure into the exhaust gas turbine is greater than the pressure in the suction system container. Exemplary is also that the control is designed as a pulse width modulated switching valve, via the map-controlled coordinated exhaust gas load and speed controlled are fed to the suction system container. An ingenious control is further, if it is formed by an up and to-functions having electrical switching valve, the exhaust gas maps characteristic or characteristic dependent releases along a characteristic of a drive system.
Maßstäbe setzen der erste Zuführungsleitungsabschnitt und der zweite Zuführungsleitungsabschnitt der Abgasrückführungsleitung, und zwar dergestalt, dass der zweite Zuführungsleitungsabschnitt sich über eine wesentliche Länge des Sauganlagenbehälters erstreckt und mit axial beabstandeten, kalibrierten Drosselöffnungen versehen ist. Und der erste Zuführungsleitungsabschnitt besitzt mehrere Bögen zur Kompensation thermischer Ausdehnungsfunktionen. Des Weiteren ist der zweite Zuführungsleitungsabschnitt an mit Abstand zueinander verlaufenden horizntalen Wänden des Sauganlagenbehälters unter Vermittlung von Halteeinrichtungen in Lage gehalten wird.The first supply line section and the second supply line section of the exhaust gas recirculation line set standards in such a way that the second supply line section extends over a substantial length of the intake system container and is provided with axially spaced, calibrated throttle openings. And the first feeder line section has multiple arcs to compensate for thermal expansion functions. Furthermore, the second supply line section is held at spaced apart horizontal walls of the suction system container by means of holding means in position.
Zur Optimierung der Temperatur des Abgasstroms des Abgasrückführungssystems ist in die Rohrabzweigung vor dem Steuerelement ein Kühler für den heißen Abgasstrom angeordnet, der mittels eines vom Kühlwasser des Kühlsystems der Brennkraftmaschine entwärmt wird und im entwärmten Zustand das Steuerelement passiert und über den ersten und den zweiten Zuführungsleitungsabschnitt in den Innenraum des Sauganlagenbehälters gelangt. Der Kühler ist dadurch gestaltungsgerecht ausgebildet, dass er einen zylinderischen Körper umfasst, der an einem ersten Endbereich eine Kühlwassereintrittsvorrichtung und eine Abgaseintrittsvorrichtung und an eine zweiten Endbereich eine Kühlwasseraustrittsvorrichtung und eine Abgasaustrittsvorrichtung besitzt. Von Vorteil ist ferner, dass benachbart der Kühlwassereintrittsvorrichtung und der Kühlwasseraustrittsvorrichtung radiale Lagerkonsolen für sich in axialer Richtung erstreckende Kühlwasserrohre vorgesehen sind.To optimize the temperature of the exhaust gas flow of the exhaust gas recirculation system, a cooler for the hot exhaust gas stream is arranged in the branch pipe before the control, which is cooled by means of one of the cooling water of the cooling system of the internal combustion engine and in the heat-treated state, the control passes and via the first and second supply line section in enters the interior of the suction system container. The radiator is formed in accordance with the design such that it comprises a cylindrical body which has a cooling water inlet device and an exhaust gas inlet device at a first end region and a cooling water outlet device and an exhaust gas outlet device at a second end region. A further advantage is that adjacent to the cooling water inlet device and the cooling water outlet device radial bearing brackets are provided for extending in the axial direction of the cooling water pipes.
Besonders geeignet ist das Abgasrückführungssystem für die Brennkraftmaschine, die als Innenbord- oder Außenbordmotor zum Antrieb eines Schiffs einsetzbar ist und wenigstens einen unter Vermittlung von zwei Pleueln mit zwei Kurbelwellen zusammenwirkenden Kolben aufweist. Diese Kurbelwellen stehen aufrecht in einem diese Kurbelwellen und den Kolben aufnehmenden Maschinegehäuse und beeinflussen ein Antriebssystem z.B. einen Propeller des Schiffs. Besagte Brennkraftmaschine arbeitet im Dieselverfahren mit Direkteinspritzung und ist mit der Abgasturboladereinrichtung versehen, umfassend die Abgasturbine und den Lader. Die Abgasturbine wird mittels des Abgasstroms beaufschlagt, der die an die Auslasseinrichtung angeschlossene Abgasleitung durchströmt. Zur baulichen Vereinfachung und Übersichtlichkeit trägt bei, dass die Abgasturboladereinrichtung und die Abgasleitung an einer oberen Stirnseite des Maschinengehäuses angeordnet sind und dass sich der Sauganlagenbehälter zumindest teilweise über die Höhe des Maschinengehäuses erstreckt. Darüber hinaus ist es von Vorteil, wenn von der Abgasleitung die Rohrabzweigung weggeführt und an das Steuerelement angeschlossen ist, von wo aus der erste Zuführungsleitungsabschnitt zum zweiten Zuführungsleitungsabschnitt verlegt ist, der in aufrechter Richtung im Innenraum des Sauganlagenbehälters verläuft und die axial beabstandeten kalibrierten Drosselöffnungen aufweist.Particularly suitable is the exhaust gas recirculation system for the internal combustion engine, which can be used as an inboard or outboard motor to drive a ship and has at least one cooperating with the intermediary of two connecting rods with two crankshafts piston. These crankshafts stand upright in a machine housing accommodating these crankshafts and the piston and influence a drive system, for example a propeller of the ship. Said internal combustion engine operates in the direct injection diesel process and is provided with the exhaust gas turbocharger device comprising the exhaust gas turbine and the supercharger. The exhaust gas turbine is acted upon by means of the exhaust gas flow, which flows through the exhaust pipe connected to the outlet device. For structural simplification and clarity contributes that the exhaust gas turbocharger device and the exhaust pipe are arranged on an upper end side of the machine housing and that the suction system container extends at least partially over the height of the machine housing. Moreover, it is advantageous if the pipe branch is led away from the exhaust pipe and connected to the control, from where the first supply line section is routed to the second supply line section, which runs in an upright direction in the interior of the suction system container and has the axially spaced calibrated throttle openings.
