Abstract

Downstream of the carburettor of an internal combustion engine, a flange at the inlet to a conical mixer has an annular distributor groove with several jets. Exhaust gas which is introduced into the flange comes pref. direct from the exhaust manifold elbow of the engine. This results both in savings in ptrol consumption of the engin and in a reduction of the CO, NOx and hydrocarbon content of the exhaust gases. It requires a minimum of appts.

Description

Beschreibung und Erläuterung zur Patent- und Hilfs-Description and explanation of the patent and auxiliary

gebrauchsmuster-Anmeldung "Vorrichtung zur Verbesserung des Benzinverbrauches bei gleichzeitiger Senkung der CO-, HC- und NO -Werte.Utility model application "Device for improving gasoline consumption with simultaneous lowering of CO, HC and NO values.

Die Erfindung betrifft eine Vorrichtung zur Einsparung des Benzinverbrauches bei gleichzeitiger Senkung der CO-, HC- und NO -Werte.The invention relates to a device for saving gasoline consumption with simultaneous lowering of CO, HC and NO values.

Es ist bekannt, Kraftstoffluftgemische vorzuwärmen und sie dem Verbrennungsraum zur Verfügung zu stellen.It is known to preheat fuel-air mixtures and the combustion chamber to provide.

Es ist weiterhin bekannt, Abgase dem Verbrennungsraum in bestimmtem prozentualen Anteil zuzuführen.It is also known to the combustion chamber in certain exhaust gases to be added as a percentage.

Die Vorrichtungen a) zur Erwärmung des Benzin-Luft-Gemisches und b) zur Einspeisung eines Teilabgasstromes sind großvolumig, aufwendig und entsprechen nicht den Anforderungen, die gewünscht sind.The devices a) for heating the gasoline-air mixture and b) for feeding in a partial exhaust gas flow are large-volume, complex and correspond not the requirements that are desired.

Es wird daher erfindungsgemäß vorgeschlagen, eine Vorrichtung zu wählen, die mit geringstem technischen Aufwand und Platzaufwand ein erforderliches Zumischen eines Abgasstromes zur Vorwärmung des Luft-Benzin-Gemisches und Verringerung, insbesondere der NOx -Werte, garantiert.It is therefore proposed according to the invention to choose a device the required mixing with the least technical effort and space requirements an exhaust gas flow to preheat the air-gasoline mixture and reduce, in particular the NOx values, guaranteed.

In der beiliegenden Zeichnung ist die erfindungsgemäße Ausführung dargestellt: mit 1) der Vergaser, mit 2) der erfindungsgemäße Düsenflansch, der eine Ringnut besitzt mit düsenartigen Bohrungen, mit 3) der Mischkörper unterhalb des Düsenflansches, der gleichzeitig als Vorwärmkammer für das Luft-, Benzin-und Abgasgemisch dient, mit 4) die Zuführungsleitung des Gemisches zum Verbrennungsraum, mit 5) der Auspuffkrümmer, mit 6) die Teilstromleitung für das Abgas zu dem Düsenflansch 2, mit 7) ein Wärmetauscher, der vorzugsweise im Auspufftopf angeordnet ist, um erfordernisgerecht das Gemisch unterhalb des Mischkörpers 3 dem Wärmetauscher zuzuführen, um es dann nach einer Aufwärmung, vorzugsweise über die Siedetemperatur des Kraftstoffes, wieder der Zufuhrleitung 4 zum Verbrennungsraum des Motors zuzuführen, mit 8) der Verbrennungsmotor.The embodiment according to the invention is shown in the accompanying drawing shown: with 1) the carburetor, with 2) the nozzle flange according to the invention, the has an annular groove with nozzle-like bores, with 3) the mixing body below of the nozzle flange, which doubles as a preheating chamber for the air, gasoline and The exhaust gas mixture is used, with 4) the feed line of the mixture to the combustion chamber, with 5) the exhaust manifold, with 6) the partial flow line for the exhaust gas to the nozzle flange 2, with 7) a heat exchanger, which is preferably arranged in the muffler to to supply the mixture below the mixing body 3 to the heat exchanger as required, then after a warm-up, preferably above the boiling temperature of the fuel, again to feed the supply line 4 to the combustion chamber of the engine, with 8) the Internal combustion engine.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellte und beschriebene Ausbildungsform beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, unterhalb des Vergasers in einem erfindungsgemäßen Düsenflansch, der eine ringnutartige Vorrichtung mit düsenlochartigen Bohrungen aufweist, einen Teilgasstrom aus dem Auspuffkrümmer über diesem Düsenflansch dem nachgeschalteten Mischkörper, der gleichzeitig auch als Vorwärmkammer dient, zuzuführen, wobei erfordernisgerecht wahlweise über einen Wärmetauscher 7 das genannte Gemisch bis auf vorzugsweise Übersiedetemperatur des Kraftstoffes vorgemischt wird, um eine Senkung des Benzinverbrauches bei gleichzeitiger Senkung der CO-, HC- und NOx -Werte zu erzielen.Of course, the invention is not limited to the above in detail The form of training shown and described is limited, but there are numerous Changes possible, but without deviating from the basic idea, below the carburetor in a nozzle flange according to the invention, which has an annular groove-like Has device with nozzle hole-like bores, a partial gas flow from the Exhaust manifold above this nozzle flange to the downstream mixing body, which at the same time also serves as a preheating chamber, and optionally over as required a heat exchanger 7, said mixture up to preferably boiling temperature The fuel is premixed to reduce gasoline consumption while at the same time Achieve a reduction in CO, HC and NOx values.
