Description

Selbstzündende, luftverdichtende Brennkraftmaschine Die Erfindung betrifft eine selbstzündende, luftverdichtende Brennkraftinaschine mit einer vom Hubraum abgezweigten und mit diesem über einen tangential in sie einmündenden Kanal in Verbindung stehenden, der Form des Brennstoffstrahles angepaßten, langgestreckten, kegelförmigen Brennkammer, die am Ende des Verdichtungshubes im wesentlichen die gesamte Verbrennungsluft aufnimmt und in die gegen Ende des Verdichtungshubes der Brennstoff eingespritzt wird. Bei den bekannten Brennkraftmaschinen dieser Art mündet der Verbindungskanal nach Lage oder Richtung derart in den Brennraum ein, daß der Luftbewegung eine starke Komponente in Richtung der Brennstoffstrahlachse aufgezwungen wird. Große und kleine Brennstofftropfen, früher und später eingespritzte Tropfen werden also durcheinandergewirbelt. Diese Vorgänge sind für den Verbrennungsablauf von Nachteil, da dieser derart beeinflußt wird, daß die Neigung zur Rußbildung erhöht wird.Self-igniting, air-compressing internal combustion engine The invention relates to a self-igniting, air-compressing internal combustion engine with one of the Displacement branched off and with this via a tangential channel opening into it connected, elongated, adapted to the shape of the fuel jet, conical combustion chamber, which at the end of the compression stroke essentially the absorbs all of the combustion air and enters it towards the end of the compression stroke Fuel is injected. In the known internal combustion engines of this type opens the connection channel according to position or direction into the combustion chamber in such a way that the Air movement imposed a strong component in the direction of the fuel jet axis will. Large and small drops of fuel, drops injected sooner and later are thus mixed up. These processes are for the combustion process disadvantageous, since this is influenced in such a way that the tendency to form soot increases will.

Erfindungsgemäß soll der Verbindungskanal zwischen Hubraum und dem kegelförmigen Verbrennungsraum in oder angenähert in der halben Längsausdehnung der Brennkammer münden. Diese Anordnung hat zur Folge, daß die Luftbewegung beim Überströmen nur eine sehr kleine Komponente in Richtung der Brennstoffstrahlachse erhält. Auf diese Weise werden die im Verlaufe der Einspritzung zeitlich nacheinander eingespritzten Tropfen in ihrer gegenseitigen räumlichen Lage durch die Wirbelbewegung der Luft nur sehr wenig beeinflußt. Durch diese Bewegung erfolgt vielmehr im wesentlichen lediglich eine Änderung der gegenseitigen Lage der jeweils -gleichzeitig eingespritzten Tropfen. In der halben Höhe des Kegels hat aber der Brennstoffstrahl einerseits schon eine Teilauflösung infolge der natürlichen Wirkung der Düse selbst erfahren, andererseits besitzen die einzelnen Tropfen eine genügende Größe, so daß diese Tropfen nicht augenblicklich die vorhandene Luftgeschwindigkeit ohne weitere Aufteilung annehmen, sondern vielmehr eine weitere Auf-Lösung in kleinere Tropfen erfolgt. Infolge der Reibung der Luft vermindert sich deren Geschwindigkeit mit zunehmendem Drehwinkel. Bei der vorliegenden Ausführung wird sie am Ende der Verdichtung in der Nähe des größten Kreisquerschnittes also geringer sein als im übrigen Verbrennungsraum. Infolge der geringeren Wärinev erluste dieses Teiles der Ladung wird das Anlassen des Motors bei dieser Anordnung erleichtert.According to the invention, the connecting channel between the displacement and the conical combustion chamber in or approximately half the length of the length open into the combustion chamber. This arrangement has the consequence that the air movement when Only a very small component flows over in the direction of the fuel jet axis receives. In this way, they are sequential in time in the course of the injection injected drops in their mutual spatial position due to the vortex movement affects the air very little. Rather, this movement essentially takes place only a change in the mutual position of the injected at the same time Drops. On the one hand, however, the fuel jet is halfway up the cone already experience a partial dissolution due to the natural effect of the nozzle itself, on the other hand, the individual drops have a sufficient size so that these drops not instantaneously the existing air velocity without further division assume, but rather a further dissolution into smaller drops takes place. Due to the friction of the air, its speed decreases with increasing Rotation angle. In the present version, it is converted into the vicinity of the largest circular cross-section must therefore be less than in the rest of the combustion chamber. As a result of the lower heat loss of this part of the load, the start-up takes place of the engine is facilitated with this arrangement.

Abb. I zeigt eine Ausführungsform einer Brennkraftmaschine mit den Merkmalen gemäß der Erfindung im senkrechten Schnitt, Abb. 2 die dazugehörige Ansicht des Zylinderkopfes von unten.Fig. I shows an embodiment of an internal combustion engine with the Features according to the invention in vertical section, Fig. 2 the associated view of the cylinder head from below.

Die kegelförmige Brennkammer 6 ist zum Teil im Zylinder i und zum Teil im Zylinderkopf 2 untergebracht. Bei der Verdichtung wird die Ladeluft durch den Kolben 3 vorn Hubraum 4. durch den Verbindungskanal in die Brennkammer 6 übergeschoben. Der Verbindungskanal 5 mündet tangential in den Kreisquerschnitt ein, der in der halben Höhe des Kegels liegt. Durch diese Anordnung des Verbindungskanals zur Brennkammer wird, wie oben näher ausgeführt, ein leichtes Anlassen, ein geringer Zündverzug bei hohen Drehzahlen sowie eine vollkommene Verbrennung bei geringstem Luftüberschuß gewährleistet.The conical combustion chamber 6 is partly in the cylinder i and for Part housed in cylinder head 2. During the compression, the charge air gets through the piston 3 at the front of the cubic capacity 4. is pushed over through the connecting duct into the combustion chamber 6. The connecting channel 5 opens tangentially into the circular cross-section, which is in the half the height of the cone. This arrangement of the connection channel to the combustion chamber As explained in more detail above, a slight starting, a slight ignition delay at high speeds as well as complete combustion with the least amount of excess air guaranteed.
