Description

Viertakteinspritzbrennkraftmaschine Die Erfindung betrifft eine Viertakteinspritzbrennkraftmaschine mit einem als Wirbelkammer ausgebildeten Nebenbrennraum, in den der Kraftstoff eingespritzt wird, und mit im Zylinderkopfboden und/ oder Kolbenboden angeordneten, aus dem Bereich der Mündung des die Wirbelkammer mit dem Hauptbrennraum verbindenden Kanals zu den Räumen unterhalb der Ein- und Auslaßventile hin verlaufenden Gasführungskanälen.Four-stroke injection internal combustion engine The invention relates to a four-stroke injection internal combustion engine with a secondary combustion chamber designed as a swirl chamber into which the fuel is injected is, and arranged in the cylinder head base and / or piston base, out of the area the mouth of the channel connecting the swirl chamber with the main combustion chamber to the Spaces below the inlet and outlet valves running gas ducts.

Mittels der Gasführungskanäle wird bei solchen Brennkraftmaschinen eine Beteiligung der in den Räumen unterhalb der Ein- und Auslaßventile vorhandenen verdichtenden Luft an der Verbrennung herbeigeführt. Aufgabe der Erfindung ist es, diese Beteiligung durch entsprechende Ausbildung der Gasführungskanäle intensiver zu gestalten. Erreicht wird dieses Ziel erfindungsgemäß dadurch, daß am Übergang der Gasführungskanäle in die Räume unterhalb der Ein- und Auslaßventile eine Stolperkante angeordnet ist.In such internal combustion engines a participation of those present in the spaces below the inlet and outlet valves compressing air brought about the combustion. The object of the invention is this participation is more intensive through appropriate training of the gas ducts to design. This goal is achieved according to the invention in that at the transition the gas ducts in the spaces below the inlet and outlet valves are a stumbling block is arranged.

Die Wirkung der Stolperkante beruht darauf, daß an ihnen aus der Wirbelkammer in den Hauptbrennraum und dort in die Gasführungskanäle übergetretenen heißen Gase eine starke Auflockerung erfahren. Durch die Stolperkanten wird die gerichtete Strömung in eine turbulente umgewandelt, d. h., die Gase breiten sich stark verwirbelt in den Räumen unterhalb der Ein- und Auslaßventile aus und vermischen sich dadurch schneller und intensiver mit der in diesen Räumen vorhandenen verdichteten Luft.The effect of the stumbling block is based on the fact that they are out of the vortex chamber hot gases that have passed into the main combustion chamber and into the gas ducts there experience a strong loosening. The directional flow is created by the stumbling blocks transformed into a turbulent one, d. That is, the gases spread strongly in swirls the spaces below the inlet and outlet valves and mix as a result faster and more intense with the compressed air present in these rooms.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Abb. 1 zeigt den Kolben einer Viertaktbrennkraftmaschine in Draufsicht auf den Kolbenboden; Abb. 2 stellt einen Schnitt nach der Linie II-II durch den Kolben nach Abb. 1 dar.Fig. 1 shows the piston of a four-stroke internal combustion engine in plan view on the piston crown; Fig. 2 shows a section along the line II-II through the Piston according to Fig. 1.

Die aus der Wirbelkammer austretenden heißen Gase treffen auf den Boden des in Abb. 1 dargestellten Kolbens 1 im Bereich a auf und werden durch Kanäle bildende Vertiefungen 2 und 3 in Pfeilrichtung den Räumen 4 bzw. 5 unterhalb der nicht gezeichneten Ein- und Auslaßventile zugeleitet. Sie vermischen sich mit der in diesen Räumen 4 und 5 befindlichen verdichteten Luft und zwingen diese, sich an der Verbrennung zu beteiligen. An Übergang eines jeden Kanals 2 und 3 zu den Räumen 4 bzw. 5 ist eine Stolperkante 6 bzw. 7 angeordnet, an der der Gasstrom, wie in Abb. 2 veranschaulicht, eine starke, zur Wirbelbildung führende Auflockerung erfährt. Die bisher gerichtete Strömung geht in eine turbulente über, was zur Folge hat, daß sich die heißen Gase in den Räumen 4 und 5 schneller und inniger mit der darin befindlichen verdichteten Luft mischen.The hot gases emerging from the swirl chamber hit the Bottom of the piston 1 shown in Fig. 1 in area a and are through channels forming wells 2 and 3 in the direction of the arrow the spaces 4 and 5 below the Intake and exhaust valves not shown. They mix with that in these rooms 4 and 5 located compressed air and force them to to participate in the incineration. At the transition of each channel 2 and 3 to the In rooms 4 and 5, there is a trip edge 6 and 7, where the gas flow, as illustrated in Fig. 2, a strong loosening leading to vortex formation learns. The previously directed flow changes into a turbulent one, which results in has that the hot gases in rooms 4 and 5 are faster and more intimate with the Mix the compressed air in it.
