Description
Einspritzbrennkraftmaschine mit Außenspeicher und herzförnügem oder kreisartigem Brennraum Gegenstand der Erfindung bildet die Anordnung einer in den Brennraum hineinzuschiebenden Luftspeicherkammer bei Einspritzbrennkraftmaschinen, insbesondere solchen mit kreisartigem oder herzförmigem Brennraum.Injection internal combustion engine with external accumulator and Herzförnügem or circular combustion chamber the subject of the invention is the arrangement of a in the Air storage chamber to be pushed into the combustion chamber in internal combustion engines, especially those with a circular or heart-shaped combustion chamber.
Durch die verschiebbare Anordnung der Speicherkammer sollen einerseits die Strömungsverhältnisse beim Ausleeren des Speichers in den Brennraum verändert werden, andererseits die Möglichkeit gegeben -werden, die Entfernung der Speichermündung bzw. des Speichertrichters von der Düsenmündung entsprechend der Durchschlagsstrecke des Brennstoffstrahles einzustellen, schließlich soll durch Einschieben des Speichers der Rauminhalt des Verdichtungsraumes und damit das Verdichtungsverhältnis der Maschine geändert werden können.Due to the displaceable arrangement of the storage chamber on the one hand the flow conditions changed when emptying the accumulator into the combustion chamber On the other hand, the possibility of removing the reservoir mouth will be given or the storage funnel from the nozzle orifice according to the breakdown distance adjust the fuel jet, finally by pushing in the memory the volume of the compression space and thus the compression ratio of the machine can be changed.
Durch diese gleichzeitig' herbeigeführte dreifache Wirkung soll mithin die Anpassung an den Belastungszustand der Brennkraftmaschine ermöglicht werden, welche die günstigsten Betriebsverhältnisse zeitigt.Through this three-fold effect brought about at the same time, the adaptation to the load condition of the internal combustion engine are made possible, which produces the most favorable operating conditions.
Besonders günstige Umstände werden hierdurch bei einventiligen Maschinen geschaffen, deren Ein- bz-w. Auslaßventil derart angeordnet ist, daß die Ventilachse mit oder nahezu mit der Zylinderachse zusammenfällt, wobei auch die weitere Anordnung getroffen sein kann, daß bei herzförmigem Brennraum die Speicherkammer an die Herzspitze und die Düse an den Herzeinschnitt verlegt werden kann.This creates particularly favorable conditions for single-valve machines created whose input or w. Exhaust valve is arranged such that the valve axis coincides with or almost coincides with the cylinder axis, the further arrangement also it can be made that, with a heart-shaped combustion chamber, the storage chamber is at the apex of the heart and the nozzle can be relocated to the heart incision.
In diesem Falle werden besonders starke und in ihrem Verlauf günstige Strömungsverhältnisse geschaffen, während gleichzeitig der Kolbenboden und die Zylinderwandung gegen die unmittelbare Berührung mit dem eingespritzten Rohöl gut abgedeckt werden.In this case they become particularly strong and favorable in their course Flow conditions created while at the same time the piston head and the cylinder wall well covered against direct contact with the injected crude oil.
Auf der Zeichnung ist in Abb. i und 2 eine Einspritzbrennkraftmasch.ine in zwei zueinander senkrechten Schnitten veranschaulicht. Die Abb. 3 und q. zeigen waagerechte Schnitte durch den herzförmigen Brennraum gemäß Abb. i und 2 und veranschaulichen zwei verschiedene Lagen des Außenspeichers. Die Abb. 5 und 6 zeigen zwei ähnliche Schnitte mit Grenzlagen für den Außenspeicher bei einem kreisartigen Brennraum.In the drawing, in Fig. I and 2, an injection internal combustion engine is shown illustrated in two mutually perpendicular sections. Fig. 3 and q. demonstrate horizontal sections through the heart-shaped combustion chamber according to Fig. i and 2 and illustrate two different layers of the external storage tank. Figs. 5 and 6 show two similar ones Sections with border positions for the external storage in a circular combustion chamber.
Hierbei ist das Ein- bzw. Auslaßventil mit a, der als Ventilkammer dienende herz-oder kreisförmige Brennraum mit b, die Einspritzdüse mit c, der Außenspeicher mit d, der Kolben mit e und der Zylinder mit f bezeichnet.The inlet or outlet valve is denoted by a, the heart-shaped or circular combustion chamber serving as a valve chamber is denoted by b, the injection nozzle by c, the external accumulator by d, the piston by e and the cylinder by f .
