Description

Brennkraftmarchine Die Erfindung betrifft eine gemischverdichtende Brenniraftmaschine mit einem Turbolader.Internal combustion engine The invention relates to a mixture-compressing engine Distillery machine with a turbocharger.

Brennkraftmaschinen leiden bekanntlich darunter, daß die von ihnen erzeugten Abgase giftig sind und die Luft verunreinigen.Internal combustion engines are known to suffer from the fact that they The exhaust gases produced are poisonous and pollute the air.

Zweck der Erfindung ist es, eine Brennkraftmaschine vorzuschlagen, deren Abgase nur einen geringeren Anteil an giftigen Gasen aufweisen.The purpose of the invention is to propose an internal combustion engine, whose exhaust gases only have a lower proportion of toxic gases.

Es sind Brennkraftmaschinen bekannt, bei denen die Abgase durch ihre Nachverbrennung erträglicher gemacht werden.There are internal combustion engines known in which the exhaust gases through their Afterburning can be made more bearable.

Außerdem sind Abgasturbolader bekannt, die die Aufgabe haben, die in den Abgasen vorhandene Energie zum Antrieb einer Turbine auszunutzen, die wiederum dem Motor zuznfiihrende Luft komprimiert, um eine vollkomsnenere Verbrennung herbeizuführen und seine Leistung zu erhbhen.In addition, exhaust gas turbochargers are known that have the task of to use existing energy in the exhaust gases to drive a turbine, which in turn Air supplied to the engine is compressed in order to bring about a more complete combustion and increase its performance.

Aufgabe der Erfindung ist es, bei einer Brennkraftmaschine, die mit einem Turbolader arbeitet, mit einfachen Mitteln eine noch bessere Verbrennung zu erzielen, durch die sich besser als bisher entgiftete Abgase ergeben und die Lei- q stung der Brennkraftmaschine erhöht wird.The object of the invention is in an internal combustion engine with a turbocharger works to achieve even better combustion with simple means achieve, through which better than before detoxified exhaust gases result and the line q performance of the internal combustion engine is increased.

Diese Aufgabe wird dadurch gelost, daß die Brennkraftmaschine zur Gewinnung eines niedrigen NOGehaltes mit einem "fetten" = 0,7) Brennstoff-Luft-Gemisch bei Sauerstoffmangel betrieben wird und den aus den Verbrennungsräumen austretenden Abgasen zur Nachverbrennung derselben vor ihrem Eintritt in den Abgasturbolader Einblaseluft im wesentlichen im Gegenstrom zugeführt wird, die durch den Abgasturbolader verdichtet ist. Dabei kann in weiterer Ausgestaltung der Erfindung ein Teil der vom Abgasturbolader verdichteten Luft zur Aufladung der Verbrennungskraftmaschine benutzt werden, während der andere Teil dieser Luft - vorzugsweise unter Zwischenschaltung von Rückschlagventilen - den Abgasrohren möglichst bald nach den Auslaßventilen oder einem vor dem Turbolader angeordneten Reaktor oder Katalysator zugeführt wird.This task is achieved in that the internal combustion engine to Obtaining a low NO content with a "rich" = 0.7) fuel-air mixture operated in the event of a lack of oxygen and those escaping from the combustion chambers Exhaust gases for afterburning the same before they enter the exhaust gas turbocharger Injection air is supplied essentially in countercurrent, which is passed through the exhaust gas turbocharger is condensed. In a further embodiment of the invention, a part of the Air compressed by the exhaust gas turbocharger for charging the internal combustion engine be used, while the other part of this air - preferably with the interposition of check valves - the exhaust pipes as soon as possible after the exhaust valves or a reactor or catalyst arranged upstream of the turbocharger.

Zur weiteren Verdichtung der Einblaseluft, die aus dem Turbolader austritt, kann im Anschluß an diesen eine Zusatzpumpe vorgesehen sein, so daß die Einblaseluft den Auspuffgasen dann kontinuierlich zugeführt wird. Diese Zusatzpumpe kann vom Motor über eine Kupplung angetrieben werden, die in Abhängigkeit von motorischen Kennwerten (Drehzahl, Ladedruck usw.) geschaltet wird.For further compression of the air blown in from the turbocharger emerges, an additional pump can be provided in connection with this, so that the Injection air is then continuously supplied to the exhaust gases. This additional pump can be driven by the motor via a coupling, which depends on the motor Characteristic values (speed, boost pressure, etc.) is switched.

Die Zuführung der komprimierten Einblaseluft ist natürlich um so leichter, je geringer der Druck in den Abgasrohren ist. Um diesen Druck also zu senken, kann ein großes Auslaßventil verwendet werden9 dessen Öffnen auf einen späten Zeitpunkt im Ablauf des betreffenden AugpufÇhutes eingestellt wird. Einem ähnlichen Zweck dient die noaan Rahmen der Erfindung anwendbare Maßnahme, die Einblae luft vor ihrer Zuführung zu den Abgasrohren zusätzlich zu erwärmen, wodurch der Nachbrennwirkungsgrad weiterhin gesteigert wird. Zu dessen Steigerung dient schließlich auch, daß die Abgasrohre zwischen den Auslaßventilen und der Abgasturbine isoliert sind.The supply of the compressed air is of course all the easier, the lower the pressure in the exhaust pipes. So to lower this pressure, you can a large exhaust valve can be used9 whose opening at a late point in time is set in the process of the relevant eye-catcher. A similar purpose serves the noaan scope of the invention applicable measure, the inlet air before their Supply to the exhaust pipes additionally heat, increasing the afterburning efficiency will continue to increase. The fact that the Exhaust pipes between the exhaust valves and the exhaust turbine are isolated.

Die ßrfindung wird im folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels, dem auch weitere Einzelheiten der Erfindung entnommen werden können, näher erläutert.The ßrfindung is shown below with reference to one in the drawing Embodiment, which also further details of the invention are taken can, explained in more detail.

Die Zeichnung zeigt in schematischer Darstellung einen Zylinderblock t einer Vier-Zylinder-BrennkFaftmaschine Die Abgase treten aus den vier Auslaßventilen 2 in vier Abgasrohre 3 aus, die in eine Abgassammelleitung 4 münden.The drawing shows a schematic representation of a cylinder block t of a four-cylinder internal combustion engine The exhaust gases emerge from the four exhaust valves 2 into four exhaust pipes 3 which open into an exhaust manifold 4.

Die Abgassammelleitung leitet die Abgase in eine Abgasturbine 5, aus der heraus die Abgase durch-einen Abgasauslaß 6 ins Freie geleitet werden. Die Turbine 5 bildet zusammen mit dem Kompressor 7 die Ladegruppe 8.The exhaust manifold directs the exhaust gases into an exhaust gas turbine 5 the exhaust gases are passed out through an exhaust outlet 6 into the open. The turbine 5 together with the compressor 7 forms the charging group 8.

Vom Kompressor 7 wird nun Frischluft 9 angesaugt, in üblicher Weise komprimiert und über die Leitung li den Einlaßventilen 12 zugeführt.Fresh air 9 is now sucked in by the compressor 7, in the usual way compressed and fed to the inlet valves 12 via the line li.

Von der Leitung 11 zweigt nun erfindungsgemäß eine Einblasleitung 13 ab, durch die Einblaseluft über Rückschlagventile 14 in die Abgasrohre 3 in einer Richtung eine blasen wird, die der Strömung der Abgase in wesentlichen entgegen gerichtet ist. In der bgassa-ielleitung 4 kann ein Reaktor oder Katalysator 15 sitzen, in dem dann im wesentlichen die Nachverbrennung stattfindet.According to the invention, an injection line now branches off from the line 11 13 from, through the air injection through check valves 14 in the exhaust pipes 3 in a Direction one is blowing, which is the flow of the exhaust gases in the opposite direction is directed. A reactor or catalyst 15 can be located in the gas pipe 4, in which the post-combustion then essentially takes place.

Außerdem kann in der Einblasleitung 13 eine Pumpe 16 sitzen, die, vom Motor angetrieben, die vom Koinpressor 7 verdichtete Einblaseluft nochmals nachverdichtet.In addition, a pump 16 can be located in the injection line 13 which, driven by the motor, the injection air compressed by the Koinpressor 7 is re-compressed again.

Die von der Pumpe 16 kornnende Einblaseleitung 13 kann am Reaktor 15 und an den Abgasrohren 3, i entlang oder auch in denselben gefthrt werden, so daß die Einblaseluft nach dem Gegenstromprinzip nochmals erwärmt wird, bevor sie in das Abgas eingeleitet wird.The injection line 13 graining from the pump 16 can be attached to the reactor 15 and along the exhaust pipes 3, i or also in the same, see above that the blown air is heated again according to the countercurrent principle before it is introduced into the exhaust gas.

Da ein wesentlicher Abbtlu von Schadstoffen in den Abgasen nur in bestimmten Drehzahl- und Lastbereichen, also hauptsächlich bei Stadtfahrten von wesentlicher Bedeutung ist, kann die' Pumpe 16 abgeschaltet werden, wenn außerhalb der genannten Bereiche gefahren wird. Dies geschieht dadurch, daß die Pumpe 16 vom Motor über eine Trennkupplung 17 angetrieben wird.Since a significant discharge of pollutants in the exhaust gases only in certain speed and load ranges, i.e. mainly when driving around town Is essential, the 'pump 16 can be switched off when outside of the mentioned areas is driven. This is done by the fact that the pump 16 from Motor is driven via a separating clutch 17.

Die Überlegungen, die zu der Erfindung geführt haben, gehen davon aus, daß die N0=-Bildvmg durch die fette" Verbrennung, d.h. durch Sauerstoffangel klein gehalten werden kann. Die noch vorhandenen CH- und C0-Anteile werden durch Nachoxydation klein gehalten oder beseitigt.The considerations that led to the invention are based on this from the fact that the N0 = image is due to rich "combustion, i.e. due to lack of oxygen can be kept small. The remaining CH and C0 shares are through Post-oxidation kept small or eliminated.

Durch die Kombination dieser beiden Merkmale, nämlich durch Nachverbrennung der Schadstoffe und Ausnutzung der dadurch entstehenden Energie- und Mengenerhöhung der Abgase in der Turbine, kann ein besserer Wirkungsgrad der Maschine erreicht werden, wobei sich auch noch saubere Abgase ergeben.' Die Abgasterbrennungs-Aufladegruppe kann durch die erfindungsgemäße Anordnung bei kleinen Abgasgegendrücken höhere Lade drücke liefern und trägt damit zu besseren Leistungs- und Verbrauchswerten bei.By combining these two features, namely through afterburning the pollutants and utilization of the resulting increase in energy and volume the exhaust gases in the turbine, a better efficiency of the machine can be achieved which also result in clean exhaust gases. ' The exhaust combustion charging group can by the arrangement according to the invention with low exhaust gas back pressures higher loading deliver pressures and thus contribute to better performance and consumption values.
