Description

Einspritz-Brennkraftmaschine mit mindestens einer im Kolben angeordneten Mischkammer Brennkraftmaschinen, bei welchen im Kolben eine Mischkammer vorgesehen ist, in welche der Brennstoff eingespritzt wird, sind seit langem bekannt. Es sind schon Brennkraftmaseh inen vorgeschlagen worden, bei welchen im Boden des Kolbens ein etwa kugelförmig ausgebildeter Mischraum vorhanden ist, in welchen der Brennstoff eingespritzt wird. Da es jedoch schwer hält, in einer solchen Mischkammer eine wirksame Durchwirbelung von Luft und Brennstoff, welche erst eine restlose Verbrennung gewährleistet, zu erzielen, kommt es oft vor, daß solche Maschinen qualmen und sich in der Mischkammer Ruß und Brennstoffrückstände ansammeln. Es ist ferner auch schon vorgeschlagen worden, die Mischkammer im Kolben solcher Maschinen mit einer seitlich liegenden Öffnung zu versehen und die Einspritzdüse so anzuordnen, daß ein Teil des Brennstoffes in den Zylinderraum und der restliche Teil durch die seitliche Offnung in die Mischkammer eingespritzt wird. Es soll damit eine wirksame Durchwirb@elung der Mischkammer erzielt werden. Bei dieser Ausführung läßt es sich jedoch nicht vermeiden, daß ein Teil des Brennstoffes gegen die die Mischkammer nach oben abschließende Wand und die Kante an der seitlichen Öffnung der Mischkammer gespritzt wird, was erfahrungsgemäß leicht zu Niederschlag von Brennstoff und Rußbildung führt. Durch die vorliegende Erfindung werden diese Nachteile vermieden.Injection internal combustion engine with at least one arranged in the piston Mixing chamber Internal combustion engines in which a mixing chamber is provided in the piston into which the fuel is injected have long been known. There are Brennkraftmaseh inen have already been proposed in which in the bottom of the piston there is an approximately spherical mixing space in which the fuel is injected. However, since it is difficult to find an effective one in such a mixing chamber Swirling air and fuel, which only ensures complete combustion, To achieve, it often happens that such machines smoke and get in the mixing chamber Build up soot and fuel residue. It has also been suggested that the mixing chamber in the piston of such machines with an opening on the side to provide and to arrange the injection nozzle so that part of the fuel in the cylinder space and the remaining part through the side opening into the mixing chamber is injected. It is intended to achieve an effective swirling of the mixing chamber will. In this embodiment, however, it cannot be avoided that a part of the fuel against the wall that closes off the mixing chamber at the top and the Edge at the side opening of the mixing chamber is injected, which experience has shown easily leads to fuel deposition and soot formation. Through the present Invention, these disadvantages are avoided.

Gegenstand vorliegender Erfindung ist eine Einspritz-Brennkraftmaschine mit mindestens einer im Kolben angeordneten Mischkammer, bei welcher die Mischkammer länglich, mit kreisförmigem Querschnitt und höhlkug elfö rmigen Enden ausgebildet ist und bei welcher in der oberen Kolbenwand eine schlitzförmige, über etwa dreiviertel der ganzen Länge der Mischkammer sich erstreckende Durchtrittsöfnung, welche die Mischkammer mit dem Zylinderraum verbindet, und seitlich am Kolben eine Eintrittsöffnung für den Brennstoff zur Mischkammer in deren Achse derart angeordnet ist, daß die vor der Erreichung der oberen Totpunktlage des Kolbens durch sie in die- Mischkammer eingespritzten ersten Brennstoffteilie .innenseitig an der oberen Wand der Mischkammer entlang geführt werden, ohne diese Wand zu berühren, und daß, während der Kolben den restlichen Weg bis zum oberen Totpunkt zurücklegt, die übrige Brennstoffmenge über die ganze obere Hälfte der Mischkammer gleichmäßig verteilt eingespritzt wird. Mit Vorteil wird dabei die schlitzförmige Durchtrittsöffnung nicht radial zur Achse der Mischkammer, sondern schräg durch die obere Kolbenwand geführt.The present invention relates to an injection internal combustion engine with at least one mixing chamber arranged in the piston, in which the mixing chamber elongated, with circular cross-section and hollow sphere Ends is formed and in which in the upper piston wall a slot-shaped, Passage opening extending over approximately three quarters of the entire length of the mixing chamber, which connects the mixing chamber with the cylinder space, and one on the side of the piston Inlet opening for the fuel to the mixing chamber arranged in the axis thereof is that the before reaching the top dead center position of the piston by them in die-mixing chamber injected first fuel part .innenseiten at the top Be guided along the wall of the mixing chamber without touching this wall, and that, while the piston covers the rest of the way to top dead center, the rest Amount of fuel evenly distributed over the entire upper half of the mixing chamber is injected. The slot-shaped passage opening is advantageous not radially to the axis of the mixing chamber, but at an angle through the upper piston wall guided.

In der Zeichnung sind beispielsweise zwei Ausführungsformen des Erfindungsgegenstandes schematisch veranschaulicht. Es zeigen: Abb. i einen axialen Schnitt durch Zylinder und Kolben einer Viertakt-Einspritz-Brennkraftmaschine, Abb. 2 einen zu Abb. i senkrechten axialen Schnitt durch den Kolben, Abb.3 einen Grundriß zu Abb. 2 und Abb. ¢ einen Grundriß eines Kolbens mit drei Mischkammern.The drawing shows, for example, two embodiments of the subject matter of the invention illustrated schematically. They show: Fig. I an axial section through a cylinder and piston of a four-stroke injection internal combustion engine, Fig. 2 a perpendicular to Fig. i axial section through the piston, Fig.3 a plan to Fig. 2 and Fig. ¢ a Plan of a piston with three mixing chambers.

Mit i ist ein Zylinder und mit 2 - ein Kolben einer Wertakt-Brenlkraftmaschine bezeiclinet. Im Kolben 2 ist eine längliche, im Querschnitt kreiförmige, mit kugelförmigen Enden versehene Mischkammer 3 gebildet, die durch eine in den Kolben 2 eingesetzte Wand 2a aus hochhitzebeständigem Stahl gegen den Zylinderraum 5 abgeschlossen ist. In dieser Wand 2a ist eine etwa über dreiviertel der ganzen Länge der Mischkammer 3 sich erstreckende schlitzförmige Durchtrittsöffnung 4. vorhanden, welche die Mischkammer 3 mit dein Zylinderraum 5 verbindet. Seitlich am Kolben 2 befindet sich eine in die obere Hälfte der Mischkammer 3 mündende Eintrittsöffnung 6, durch welche vor Erreichung der oberen Totpunktlage des Kolbens 2 durch eine in der Zylinderwandung vorgesehene Brennstoffdüse 7 der Brennstoff eingespritzt wird. Die Anordnung ist dabei so getroffen, daß in der oberen Totpunktlage des Kolbens 2 die. Achse der Brennstoffdüse 7 mit der Mittelachse der Mischkammer zusammenfällt.With i is a cylinder and with 2 - a piston of a Wertakt-Brenlkraftmaschine labeled. In the piston 2 is an elongated, circular cross-section, with spherical Mixing chamber 3 provided with ends is formed by a mixing chamber 3 inserted into the piston 2 Wall 2a made of heat-resistant steel is closed off from the cylinder space 5. In this wall 2a is about three quarters of the entire length of the mixing chamber 3 extending slot-shaped passage opening 4. present, which the mixing chamber 3 connects to your cylinder space 5. On the side of the piston 2 there is an in the upper half of the mixing chamber 3 opening inlet opening 6 through which before Reaching the top dead center position of the piston 2 by means of one in the cylinder wall provided fuel nozzle 7, the fuel is injected. The arrangement is taken so that in the top dead center position of the piston 2 the. Axis of Fuel nozzle 7 coincides with the central axis of the mixing chamber.

Beim Kompressionshub, d. h. bei der Aufwärtsbewegung des Kolbens 2 wird die im Zylinderraum 5 befindliche Luft durch die schlitzförmige Durchtrittsöffnung 4 in die Miselikatnmer 3 verdrängt, wobei in dieser eine intensive Wirbelung erzeugt wird. L m diesen Luftwirbel noch zu verstärken, ist es von Vorteil, die schlitzförmige Durchtrittsbffnung 4. nicht radial zur Achse der Mischkammer 3, sondern schräg durch die Wand 2a hindurchzuführen. Hat die obere Kante der Brennstoffeintrittsöffnung 6 vor Erreichung der oberen Totpunktlage des Kolbens 2 die Mitte der Brennstoffdüse 7 um etwa den halben Streuwinkel derselben überschritten, so werden von derselben die ersten Brennstoffteile durch die Eintrittsöffnung 6 in den obersten Teil der Mischkammer 3 derart der oberen Wand 2" entlang eingespritzt, daß sie diese Wand in keinem Fall berühren. Durch die heiße Verbrennungsluft werden diese Brennstoffteile in der üblichen Weise zur Entzündung gebracht. Während der Kolben 2 mit der Mischkammer 3 seinen restlichen Weg zur oberen Totpunktlage zurücklegt, wird die übrige Brennstoffmenge in die Mischkammer 3 eingespritzt und somit die ganze obere Hälfte der Mischkammer 3 von den Brennstoffstrahlen gleichmäßig durchdrungen. Der Brennstoff wird mit der in der Mischkammer 3 in Wirbelung versetzten und der immer noch durch -die Durchtrittsöffnung ¢ in diese eintretenden Luft sehr gut vermischt. Diese sehr gute Durchmischung des Brennstoffes und der Verbrennungsluft wirkt sich in einer praktisch vollständigen, rauch- und geruchlosen Verbrennung aus. Einspritz-Brennkraftmaschinen gemäß der Erfindung zeichnen sich dank der guten Mischung von Brennstoff und Luft durch einen bei jeder Belastung klopffreien Gang, wodurch sämtliche Teile geschont werden, und gute, praktisch restlose Ausnutzung des Brennstoffes, somit geringen Brennstoffverbrauch aus. Der Einspritzdruck kann niedriger gewählt werden als sonst bei ähnlichen Maschinen üblich, was sich ebenfalls vorteilhaft auswirkt.During the compression stroke, i. H. on the upward movement of the piston 2 the air located in the cylinder space 5 passes through the slot-shaped passage opening 4 is displaced into the Miselikatnmer 3, creating an intense vortex in this will. In order to intensify this air vortex, it is advantageous to use the slot-shaped Passage opening 4. not radially to the axis of the mixing chamber 3, but through at an angle pass through the wall 2a. Has the top edge of the fuel inlet opening 6 before reaching the top dead center position of the piston 2, the center of the fuel nozzle 7 is exceeded by about half the scattering angle of the same, then of the same the first fuel parts through the inlet opening 6 in the uppermost part of the Mixing chamber 3 is injected along the top wall 2 ″ along this wall never touch it. The hot combustion air makes these fuel parts inflamed in the usual way. While the piston 2 with the mixing chamber 3 covers the rest of the way to the top dead center position, the remaining amount of fuel is injected into the mixing chamber 3 and thus the entire upper half of the mixing chamber 3 penetrated evenly by the fuel jets. The fuel comes with the set in vortex in the mixing chamber 3 and still through the passage opening ¢ very well mixed in this incoming air. This very good mixing of the Fuel and the combustion air acts in a practically complete, smokeless and odorless combustion. Injection internal combustion engines according to Invention stand out thanks to the good mixture of fuel and air by one Knock-free gear with every load, which protects all parts, and good, practically complete utilization of the fuel, thus low fuel consumption the end. The injection pressure can be selected to be lower than otherwise with similar machines common, which is also beneficial.

Bei der Ausführungsform gemäß Abb. ,1 sind im Kolben 2 drei um 120' zueinander versetzte Mischkammern 3 vorgesehen, welche je an ihrem nach außen zu liegenden Ende eine Eintrittsöffnung 6 für den Brennstoff und oben eine Durchtrittsöffnung 4. aufweisen und für welche in der Zylinderwandung je eine Einspritzdüse vorgesehen ist.In the embodiment according to Fig. 1, three by 120 'are in the piston 2 staggered mixing chambers 3 are provided, each of which is towards the outside lying end an inlet opening 6 for the fuel and above a passage opening 4. have and for each of which an injection nozzle is provided in the cylinder wall is.
