Abstract

The invention relates to a fuel-jet divider in the combustion chamber of a self-igniting diesel internal combustion engine, the said divider interacting with an injection nozzle in the form of a single-jet or pintle nozzle arranged in the cylinder head, lying in the path of the fuel jet from the injection nozzle and, by means of integrated diversion passages, dividing the fuel jet into numerous fuel jets and guiding these separately into the combustion chamber.

Description

Die Erfindung betrifft einen Kraftstoffstrahlteiler im Brennraum einer selbstzündenden Diesel-Brennkraftmaschine gemäß den im Oberbegriff des Patentanspruchs 1 angegebenen Merkmalen.The invention relates to a fuel jet splitter Combustion chamber of a self-igniting diesel engine according to the specified in the preamble of claim 1 Characteristics.

Bekanntlich werden bei luftverteilenden, direkteinsprit­ zenden Diesel-Brennkraftmaschinen Mehrlochdüsen verwendet, die den Kraftstoff durch die Spritzlöcher in den freien Brennraum einspritzen, um eine möglichst gleichmäßige Verteilung des Kraftstoffes in der im Brennraum strömenden Luft zu erzielen.As is known, direct air injection is used for air distribution zenden diesel internal combustion engines used multi-hole nozzles, which free the fuel through the spray holes Inject the combustion chamber so that it is as uniform as possible Distribution of the fuel flowing in the combustion chamber To achieve air.

Als Nachteil der relativ aufwendigen Mehrlochdüsen ist anzusehen, daß sie abhängig von der eingespritzten Kraft­ stoffmenge verschieden gute Verteilwirkungsgrade haben. Es ist aber auch bekannt, eine gute Kraftstoffverteilung mit weniger aufwendigen Einlochdüsen zu erreichen, deren ein­ ziger Kraftstoffstrahl auf eine durch eine Bodenerhebung im Brennraum gebildete Prallfläche auftrifft, um den Kraftstoffstrahl gleichmäßig nach allen Seiten in den freien Brennraum abzulenken (DE 33 27 998 A1).The disadvantage of the relatively complex multi-hole nozzles consider that it depends on the force injected quantity of substance have differently good distribution efficiencies. It but is also known to have a good fuel distribution to achieve less complex single-hole nozzles, their one fuel jet onto a through a bump baffle formed in the combustion chamber hits the  Fuel jet evenly in all directions to deflect the free combustion chamber (DE 33 27 998 A1).

Auch bei dieser Ausführung zeigte es sich, daß die Kraft­ stoffverteilung und die Vermischung mit der Luft im Brennraum noch nicht ausreichend zufriedenstellend ist.This version also showed that the force distribution and mixing with the air in the Combustion chamber is not yet sufficiently satisfactory.

Der Erfindung liegt die Aufgabe zugrunde, Maßnahmen im Brennraum vorzusehen, durch die eine wesentliche Verbes­ serung der Kraftstoffverteilung und somit eine bessere Vermischung des Kraftstoffes mit der im Brennraum strö­ menden Luft erzielbar ist.The invention has for its object measures in Provide combustion chamber through which an essential verb improvement of the fuel distribution and thus a better one Mixing of the fuel with that in the combustion chamber air can be achieved.

Zur Lösung der Aufgabe dienen die im Kennzeichen des Pa­ tentanspruchs 1 angegebenen Merkmale.To solve the problem, use the in the characteristics of Pa Features 1.

Durch den besonderen Kraftstoffstrahlteiler wird erreicht, daß sich keine geschlossene Kraftstofffläche in Höhe des sich seitwärts im Brennraum ausbreitenden Kraftstoffes ergibt, sondern daß die durch die Umlenkkanäle in ge­ trennter Form zahlreich austretenden Kraftstoffstrahlen der im Brennraum strömenden Luft eine für eine gute Ver­ mischung effektivere Fläche bieten. Höhe Verbrennungsge­ räusche werden reduziert, die Stickoxid- und Rußemission weiter vermindert und die geringe Leistungsdichte ver­ mieden, ohne den Vorteil des sparsamen spezifischen Ver­ brauches einzubüßen.The special fuel jet splitter ensures that there is no closed fuel area in the amount of fuel spreading sideways in the combustion chamber results, but that through the deflection channels in ge separated form numerous escaping fuel jets the air flowing in the combustion chamber is one for a good ver provide more effective area. Combustion level Noise is reduced, nitrogen oxide and soot emissions further reduced and the low power density ver avoided without the benefit of economical specific ver need to lose.

In den Unteransprüchen sind noch förderliche Weiterbil­ dungen enthalten.In the subclaims there are still helpful further developments included.

Fig. 5 den Kraftstoffstrahlteiler in Draufsicht und in teilweise geschnittener Darstellung. Fig. 5 shows the fuel jet splitter in plan view and in a partially sectioned view.

Bei dem in Fig. 1 gezeigten Teil einer selbstzündenden, direkteinspritzenden Diesel-Brennkraftmaschine ist ein in OT-Stellung befindlicher Kolben mit 1, ein Zylinderkopf mit 2, eine im Zylinderkopf 2 angeordnete Einspritzdüse mit 3, ein in den Kolbenboden 4 eingelassener Brennraum mit 5 und ein Kraftstoffstrahlteiler mit 6 bezeichnet.In the example shown in Fig. 1 part of a self-igniting, direct-injection diesel internal combustion engine is an in-TDC position of piston 1, cylinder head 2, one arranged in the cylinder head 2, injection nozzle 3, a recessed in the piston crown 4 combustion chamber 5 and a fuel jet splitter designated 6 .

Dieser Kraftstoffstrahlteiler 6 ragt als zylindrisch ge­ formter Körper mittig in den Brennraum 5 hinein, ist ein­ teilig mit dem Kolbenboden 4 verbunden und liegt im Weg des einzigen Kraftstoffstrahles 7 der Einspritzdüse 3. Der Kraftstoffstrahl 7 gelangt über eine mit Abstand von dem Lochende 8 der Einspritzdüse 3 liegende Eintrittsöffnung 9 des Kraftstoffstrahlteilers 6 in bogenförmig verlaufende Umlenkkanäle 10 und wird in zahlreiche kleine Kraftstoff­ strahlen aufgeteilt, die durch Austrittsöffnungen 11 am zylindrischen Umfang des Kraftstoffteilers 6 gleichmäßig nach allen Seiten in den ringförmigen freien Brennraum 5 unter Bildung von kleinsten Zwischenräumen zwischen den einzelnen Kraftstoffstrahlen reichen und sich mit der in dem Brennraum 5 strömenden Luft optimal vermischen.This fuel jet splitter 6 projects as a cylindrically shaped body into the center of the combustion chamber 5 , is connected in part to the piston crown 4 and lies in the path of the single fuel jet 7 of the injection nozzle 3 . The fuel jet 7 passes through an inlet opening 9 of the fuel jet splitter 6 , which is at a distance from the hole end 8 of the injection nozzle 3 , into arcuate deflection channels 10 and is divided into numerous small fuel jets which flow through outlet openings 11 on the cylindrical circumference of the fuel splitter 6 evenly on all sides the annular free combustion chamber 5 to form the smallest gaps between the individual fuel jets and mix optimally with the air flowing in the combustion chamber 5 .

Der Kraftstoffstrahlteiler 6 gemäß Fig. 2 ist mit der Einspritzdüse 3 fest verbunden und ragt zylinderkopfseitig in den Brennraum 5 hinein. Der Abstand zwischen dem Lo­ chende 8 der Einspritzdüse 3 und der Eintrittsöffnung 9 des Kraftstoffstrahlteilers 6 entspricht demjenigen nach Fig. 1, ebenso demjenigen in Fig. 3, in der der Kraft­ stoffstrahlteiler 6 an seinem oberen Ende einen Befesti­ gungsring 12 aufweist, der am Zylinderkopf 2 fixiert ist.The fuel beam splitter 6 as shown in FIG. 2 is fixedly connected to the injection nozzle 3 and the cylinder head side protrudes into the combustion chamber 5. The distance between the Lo chende 8 of the injector 3 and the inlet opening 9 of the fuel jet splitter 6 corresponds to that of FIG. 1, as well as that in Fig. 3, in which the fuel jet splitter 6 has a fastening ring at its upper end 12 , which on the cylinder head 2 is fixed.

Die Umlenkkanäle 10 sind durch am Außenrandbereich des Kraftstoffstrahlteilers 6 vorgesehene und am Umfang dieses Kraftstoffstrahlteilers gleichmäßig verteilte Führungs­ stege 13 getrennt.The deflection channels 10 are separated by guide webs 13 provided on the outer edge region of the fuel jet divider 6 and evenly distributed on the circumference of this fuel jet divider.
