Description

Verbesserung der Gemischverbrennnng durcK.WibbelZinrichtung und Abgasrückführung Verfahren zum Erzeugen einer solchen Verwirbelung nach dem Patent. (Patentanmeldung P 29 31 863,6) Bei üblichen Verbrennungen im Motor müssen zu große Kraftstoffteile verbrannt werden.Improvement of the mixture combustion thanks to the swirl device and exhaust gas recirculation Method for generating such a turbulence according to the patent. (Patent application P 29 31 863.6) In the case of normal burns in the engine, fuel parts that are too large to be burned.

Um dies zu verhindern sollten Leitwerke (Figur 3) in den Ansaugraum der Verbrennungsluft gebracht werden, Dabei vermischen sich die fetten Schichten innig mit Verbrennungsluft.To prevent this, tail units (Figure 3) should be in the intake chamber the combustion air, the fat layers are mixed together intimate with combustion air.

Ergebnis ist, daß dadurch eine starke Co-Minimierung eintritt, sowohl bei Neuen, als auch bei älteren Modellen.The result is that there is strong co-minimization, both with new, as well as with older models.

Durch Anreicherung der Ansaugluft mit Verbrennungsluft, welche über den Ansaugstutzen (4) der Wirbeleinrichtung zum Verbrennungsraum gelangt bewirkt, daß der Nox-Wert und der Co-Wert gesenkt werden, Die Kosten der leicht herzustellenden Trichter und Halteplatten hierfür mit Rohranschluß für verbrannte Abgase, stehen in keinem Verhältnis der erreichbaren Sehadstoffreduzierung, Auch unterliegen diese Teile keinem Verschleiß.By enriching the intake air with combustion air, which over causes the intake port (4) of the vortex device to reach the combustion chamber, that the Nox value and the Co value are lowered, The cost of the easy-to-manufacture Funnels and retaining plates for this with pipe connection for burnt exhaust gases are available in no proportion to the achievable reduction in visual pollutants, also subject to this Parts do not wear out.

Die beschriebene Einrichtung wurde seit 1978 in vielen Testfahrten an in- und ausländischen Motoren, Ein- und Mehrzylindern gründlich erprobt.The facility described has been used in many test drives since 1978 Thoroughly tested on domestic and foreign engines, single and multi-cylinders.

Es wurden dabei folgende Vorteile festgestellt: - Weicher, ruhiger Lauf des Motors, - Weiches, ruckfreies Beschleunigen.The following advantages were found: - Softer, quieter Running of the engine - soft, jerk-free acceleration.

- Besseres Drehmoment - Schadstoffreduzierung Co und Nox- Better torque - pollutant reduction Co and Nox

Claims (1)

Ansprüche: Gemischverbesserung bei Vergasermotoren durch Einbau der Wirbeleinrichtung (Figur 3) bei Einvergaser oder Wirbeleinrichtung (Figur 4+5) bei Mehrfachvergasern in den Ansaugkanal, Wirbeltopfhalter mit Querbohrung um Abgas mit Ansaugluft zu vermischen (Figur 2) und damit Co u. Nox Schadstoffe zu reduzieren,Claims: Mixture improvement in carburettor engines by installing the Vortex device (Figure 3) with single carburetor or vortex device (Figure 4 + 5) at Multiple carburetors in the intake duct, vortex pot holder with cross hole around the exhaust gas to mix with intake air (Figure 2) and thus to reduce Co and Nox pollutants,
