Abstract
Description
Die Entwicklung von mehr Energie im Abgas hat mit dem duothermischen D.I.-Brennverfahren im Motor einen hohen Stand erreicht. Gleichgültig, ob mit Benzin, Diesel oder Pflanzenöl gefahren wird, entfällt bei diesem Verfahren wärmeleitendes Aluminium im Brennraum ebenso wie Wasserman tel und Kühlrippen. Die dadurch entstehende höhere Wärme in der Arbeitsluft kommt etwa zur Hälfte dem Abgas zugute, wo eine bessere Nutzung erforderlich ist.The development of more energy in the exhaust gas has with the duothermal D.I. Status reached. No matter whether with petrol, diesel or Vegetable oil is not used in this process heat-conducting aluminum in the combustion chamber as well as Wasserman tel and cooling fins. The resulting higher heat in About half of the working air benefits the exhaust gas, where better use is needed.
Um diesen thermodynamischen Gewinn nicht an verlustreiche Anbaugeräte wie Rußfilter, Katalysatoren und deren Heizanla gen wieder verlorengehen zu lassen, wird vorgeschlagen, die gesteigerte Abgasenergie für bessere Abgasemissionen zu mobilisieren. Will man den Katalysator sparen, werden alle Schademissionen reduziert, wenn mehr Luft in den Zylinder kommt, als zur Verbrennung gebraucht wird.In order not to lose this thermodynamic gain Attachments such as soot filters, catalysts and their heating system to be lost again, it is proposed that increased exhaust gas energy for better exhaust emissions mobilize. If you want to save the catalyst, everyone will Crush emissions are reduced when more air is in the cylinder comes when is needed for combustion.
Anstelle von Abgasrückführung in die Brennraumluft, bringt auch jedes Mehr an Frischluftmasse über den Bedarf an Sauer stoff hinaus eine Absenkung der Brenntemperatur im Verhält nis der zu erwärmenden Masse eine kleinere Maximaltempera tur und weniger NOx. Ein erhöhter Luftüberschuß bringt außerdem den Vorteil einer wesentlichen Absenkung von CO, CH und anderer Emissionen, so daß Rußfilter und Katalysato ren überflüssig sind; dies besonders im unteren Drehzahl bereich, wo bisher Luftmangel herrschte, ganz abgesehen davon, daß bei dieser Lösung der Emissionsprobleme auch Ver brauch und CO₂ gesenkt werden und weniger Drehzahl für die gleiche Leistung nötig wird (Motorgeräusch).Instead of exhaust gas recirculation into the combustion chamber air also every increase in fresh air mass over the need for acid a reduction in the firing temperature in the ratio a smaller maximum temperature depending on the mass to be heated tur and less NOx. An increased excess of air brings also the advantage of a significant reduction in CO, CH and other emissions, so that soot filter and catalytic converter ren are superfluous; this is particularly the case in the lower speed not to mention the area where there was previously a lack of air of the fact that with this solution of the emission problems also Ver consumption and CO₂ are reduced and less speed for the same power is required (engine noise).
Nachdem also die Optimierung der thermodynamischen Vorgänge im Zylinder einen gewissen Abschluß erreicht hat, muß also nur die Nutzung der vergrößerten Abgasenergie so verbessert werden, daß trotz Emissionsvorschriften auch der thermodyna mische Wirkungsgrad in der Abgasnutzung so verbessert wird, daß damit sogar die mechanischen Verluste in der Kolbenarbeit ausgeglichen werden. Die effektive Leistung des Motors wird gleich oder größer als die induzierte Kol benleistung.So after optimizing the thermodynamic processes has reached a certain degree in the cylinder, must only the use of the increased exhaust gas energy so improved be that, despite emission regulations, the thermodyna mixing efficiency in exhaust gas use improved will that even the mechanical losses in the Piston work can be compensated. The effective performance of the engine becomes equal to or greater than the induced Kol performance.
Über den Erhalt der Wärmeenergie im Abgas und die optimierte Energienutzung im Abgas werden auch Schadstoffe wie Blei oder Benzol im Benzin nicht mehr gebraucht, weil reines Benzin dann im Selbstzünder mit den geschilderten Fort schritten mit wesentlich besserem Wirkungsgrad und ganz ohne nachgeschaltete Geräte am umweltfreundlichsten ver brannt wird.About the preservation of the thermal energy in the exhaust gas and the optimized Energy use in the exhaust gas will also pollutants such as lead or benzene in gasoline is no longer needed because it is pure Gasoline then in the diesel with the Fort described steps with much better efficiency and completely most environmentally friendly without downstream equipment is burned.
Die bisherigen Energieverluste in der vorgeschalteten Tur boaufladung durch eine Abgasturbine begannen bisher schon im Zylinderkopf damit, daß die Abgase zwar im Ventildurch gang auf die hohe Geschwindigkeit gebracht wurden, wie sie in der Turbine gebraucht wird, durch die Irrwege des Abga ses, das erst alle Nebenkanäle und den Abgassammler auffül len mußte, bevor es zur Turbine kam, entstanden große Ener gieverluste sowohl thermisch wie dynamisch. Erst mit der Restenergie wurde in der Turbinenspirale wieder die nötige Gasgeschwindigkeit zum Turbinenantrieb erzeugt. Eine Nutzung der Sogwirkung beschleunigter Gassäulen im Auslaßrohr, wie sie für größere Motoren mit konstanter Drehzahl von Bedeu tung ist, kann auch erst mit einer nicht unterbrochenen Strömung vom Ventil bis zur Turbine erfolgen.The previous energy losses in the upstream door Bo charging by an exhaust gas turbine has already started in the cylinder head so that the exhaust gases pass through the valve were brought to the high speed as they were is used in the turbine through the wrong paths of the Abga This first fills all the secondary ducts and the exhaust manifold Before the turbine came into being, large energies had to be built casting losses both thermally and dynamically. Only with the Residual energy became necessary again in the turbine spiral Gas velocity generated for the turbine drive. One use the suction effect of accelerated gas columns in the outlet pipe, such as for larger engines with constant speed from Bedeu can only be started with an uninterrupted one Flow from the valve to the turbine.
Mit der Steigerung der Abgasenergie über höhere Ladedrücke wird auch die Entwicklung der Luftlagerung des Turbolaufes als weitere Verbesserung der Turbinenleistung vorangetrie ben. With the increase in exhaust gas energy via higher boost pressures will also develop the air bearing of the turbo barrel as a further improvement in turbine performance ben.

Der Flansch 1 mit dem Einlauf- und Dichtungsteil 2 ist auf kürzestem Weg an die Auslaßöffnung 3 des Ventiles heran gebracht. Eine Verbindung zwischen den Zylindern 4, 5, 6 im oder außerhalb des Zylinderkopfes 7 ist nicht vorgesehen.The flange 1 with the inlet and sealing part 2 is brought up to the outlet opening 3 of the valve by the shortest route. A connection between the cylinders 4 , 5 , 6 in or outside the cylinder head 7 is not provided.
Der Querschnitt der Auslaßöffnung 3 ergibt sich aus dem Ventilsitzdurchmesser 8 abzüglich des Ventilschaftquer schnitts 9 im Bereich des Ventilsitzes. Diese Querschnitts fläche wird in den folgenden Auslaßrohren 10, 11, 12 nicht überschritten. In der Bündelungsstelle 13 wird je nach Art des praktischen Einsatzes mit verschiedenen Düsenausführun gen 14, 15 ein Unterdruck in den Nebenrohren erzeugt und da das Gas mit erhöhter Geschwindigkeit dem Turbinenrad 16 zu geführt. Über die Welle 17 erfolgt in der herkömmlichen Weise der Antrieb des Luftverdichters und die Zufuhr der Luft zu den Zylindern 4, 5 und 6. Diese Luftzufuhr ist nicht Gegenstand der Anmeldung.The cross section of the outlet opening 3 results from the valve seat diameter 8 minus the valve stem cross section 9 in the region of the valve seat. This cross-sectional area is not exceeded in the following outlet pipes 10 , 11 , 12 . In the bundling point 13 , depending on the type of practical use with various nozzle designs 14 , 15, a negative pressure is generated in the secondary tubes and since the gas is fed to the turbine wheel 16 at increased speed. The shaft 17 drives the air compressor and supplies the air to the cylinders 4 , 5 and 6 in the conventional manner. This air supply is not part of the registration.
In Fig. 2 ist das gleiche System dargestellt, jedoch sind hier die einzelnen Auslaßrohre 18, 19, 20 am Umfang des Tur binenrades 21 angeordnet.In Fig. 2 the same system is shown, but here the individual outlet pipes 18 , 19 , 20 are arranged on the circumference of the turbine wheel 21 .
Die letzte Gasbeschleunigung erfolgt hier im Teil 22. Dessen Ausführung richtet sich nach der Anzahl der Zylinder und dem Durchmesser des Turbinenrades 16.The last gas acceleration takes place here in part 22 . Its design depends on the number of cylinders and the diameter of the turbine wheel 16 .
