Abstract

A differently ignited combustion engine comprises three spark plugs in the combustion chamber. One is in the center of the cylinder head with two additional plugs situated between the valve openings and the edge of the chamber. There are the usual additional mechanical and electrical components.

Description

Fremdgezündete Brennkraftmaschinen dienen in erster Linie als Antrieb von Kraftfahrzeugen.Third-party internal combustion engines serve primarily as a drive of motor vehicles.

Aufgrund unvollständiger Verbrennung weisen die bisher verwendeten Brennkraftmaschinen einen hohen Anteil an Abgasrohemissionen auf. Verringerungen der Abgasrohemissionen sind bisher nur durch Maßnahmen zu erreiehen, welche das Start-, Lauf-, und Leistungsverhalten dieser Maschinen sowie den Treibstoffverbrauch negativ beeinflussen.by virtue of incomplete Combustion have the previously used internal combustion engines high proportion of exhaust emissions. Reductions in exhaust emissions are so far only through measures to get the start, run, and performance of this Machines and negatively affect fuel consumption.

Das Problem der unvollständigen Verbrennung liegt an den zu langen Flammwegen im Brennraum. Bei großen Zylinderdurchmessern brennt das angesaugte Kraftstoffluftgemisch nicht vollständig ab. Besonders in den kühleren Randzonen des Zylinders wird das Gemisch nicht sicher entflammt. Die Verbrennung neigt an diesen Stellen zum Erlöschen (Quench-Effekt). Das Abgas ist entsprechend mit HC (unverbranntem Kohlenwasserstoff) angereichert. Versucht man diesem Nachteil durch entsprechende Frühzündung und fettem Gemisch entgegenzuwirken, leidet das Laufverhalten der Brennkraftmaschine. Schadstoffausstoß wie CO und NOx sowie Kraftstoffverbrauch steigen. Außerdem wird die Verwendung von entsprechend klopffestem Kraftstoff erforderlich.The Problem of incomplete Combustion is due to the long flame paths in the combustion chamber. at huge Cylinder diameters burn the sucked in fuel air mixture not completely off. Especially in the cooler ones Edge zones of the cylinder, the mixture is not reliably inflamed. The combustion tends to extinguish at these points (quench effect). The Exhaust gas is corresponding to HC (unburned hydrocarbon) enriched. Tried this disadvantage by appropriate pre-ignition and counteract fat mixture, the running behavior of the internal combustion engine suffers. Pollutant emissions like CO and NOx as well as fuel consumption are rising. In addition, the use is of correspondingly knock-resistant fuel required.

Der im Patentanspruch angegebenen Erfindung liegt das Problem zugrunde, das angesaugte Kraftstoffluftgemisch in möglichst kurzer Zeit vollständig zu entflammen und somit eine effiziente Verbrennung einzuleiten.Of the in claim the invention is based on the problem the aspirated fuel air mixture in the shortest possible time completely inflame and thus initiate efficient combustion.

Dieses Problem wird durch die im Patentanspruch aufgeführten Merkmale der Erfindung gelöst.This Problem is solved by the features of the invention listed in the claim solved.

Im Vergleich zu Brennkraftmaschinen nach dem Stand der Technik bietet diese Erfindung folgende Vorzüge:

  • – Die Schadstoffemission ist erheblich niedriger.
  • – Das Start-, Lauf- und Leistungsverhalten wird erheblich verbessert.
  • – Der Kraftstoffverbrauch ist geringer.
  • – Der Zündzeitpunkt kann erheblich später erfolgen.
  • – Die mechanische Belastung der Bauteile des Kurbeltriebs wird reduziert.
  • – Die Verwendung von weniger klopffestem Kraftstoff wird möglich.
Compared to prior art internal combustion engines, this invention offers the following advantages:
  • - The pollutant emission is considerably lower.
  • - The start, running and performance is significantly improved.
  • - The fuel consumption is lower.
  • - The ignition can be done much later.
  • - The mechanical stress on the components of the crank mechanism is reduced.
  • - The use of less knock-resistant fuel is possible.

Ein Ausführungsbeispiel ist im Anhang "Zeichnungen" in Bild 1 dargestellt und wird im folgenden näher beschrieben:
Um die Flammwege zu verkürzen werden in den Brennraum (Bild 1/Detail A) zusätzliche Zündkerzen (Bild1/Detail 1) eingebracht. Diese sind möglichst im Randbereich bzw. je nach Brennraumform entsprechend angeordnet.An embodiment is shown in the appendix "drawings" in Figure 1 and is described in more detail below:
To shorten the flame paths, additional spark plugs (Fig. 1 / Detail 1) are inserted into the combustion chamber (Fig. 1 / Detail A). These are arranged as possible in the edge region or depending on the combustion chamber shape.

Die zusätzlichen Zündkerzen dienen als Nebenzündkerzen und können in den Abmessungen kleiner sein als die Hauptzündkerze (Bild 1/Detail 2)The additional spark serve as Nebenzündkerzen and can be smaller in size than the main spark plug (picture 1 / detail 2)

Das Kraftstoff-Luft-Gemisch im Brennraum wird an 3 Stellen im Regelfall gleichzeitig gezündet.The Fuel-air mixture in the combustion chamber is at 3 places in the rule ignited simultaneously.

Die Flammfront breitet sich von der Hauptzündkerze gleichmäßig mit stetig weniger werdenden Energie in Richtung Zylinderwand aus. Gleichzeitig breiten sich die von außen gezündeten Flammfronten zur Brennraummitte hin aus.The Flame front spreads evenly from the main spark plug steadily decreasing energy towards the cylinder wall. At the same time broad yourself from the outside ignited Flame fronts to the combustion chamber center out.

Die Verbrennung ist somit an den Randzonen ebenso effizient und vollständig wie in der Mitte des Brennraumes wo die Hauptzündkerze sitzt.The Combustion is therefore as efficient and complete as on the fringes in the middle of the combustion chamber where the main spark plug sits.

Ein weiteres Ausführungsbeispiel ist in Bild 2 dargestellt und wird im folgenden näher beschrieben:
Bei Brennkraftmaschinen mit 3 Ventilen pro Zylinder (2 Einlass – und 1 Auslassventil) werden die zusätzlichen Zündkerzen im Randbereich neben dem Auslassventil angeordent.Another embodiment is shown in Figure 2 and is described in more detail below:
For internal combustion engines with 3 valves per cylinder ( 2 Inlet and 1 Exhaust valve), the additional spark plugs are arranged in the peripheral area adjacent to the exhaust valve.

Für besondere Brennraumformen ist eine phasenversetzte Zündung und, eine entsprechend andere Anordnung der Nebenzündkerzen sowie eine Kombination aus beidem möglich. Dies ändert jedoch nichts am Grundprinzip der Erfindung.For special Combustion chamber shapes are a phase-shifted ignition and, respectively, a different one Arrangement of secondary spark plugs as well as a combination of both possible. This does not change anything at the basic principle of the invention.
