Description

Einspritzbrennkraftmaschine mit zweiteiligem Zündkammereinsatz Gegenüber den bekannten Einspritzbrennkraftmaschinen mit zweiteiligem Zündkammereinsatz kennzeichnet sich die Einspritzbrennkraftmaschine nach der Erfindung dadurch, daß der als Verdampfer dienende, in an sich bekannter Weise napf-, hut- oder trogartige Unterteil des Zündkammereinsatzes mit seiner konischen Außenfläche glatt und genau auf seinen Sitz passend ausgebildet ist und vom Oberteil, der als Haltemutter dient und in die Zündkammer ragt, scharf angepreßt wird.Injection internal combustion engine with two-part ignition chamber insert opposite the known internal combustion engines with two-part ignition chamber insert the internal combustion engine according to the invention in that the evaporator serving, in a manner known per se, cup, hat or trough-like lower part of the ignition chamber insert with its conical outer surface designed to be smooth and to fit exactly on its seat and from the upper part, which serves as a retaining nut and protrudes into the ignition chamber, sharp is pressed.

Die besondere Ausbildung des Verdampfers ergibt beim Einsetzen in den Zylinderkopfboden den Vorteil, daß die Zündkanäle ,.jeweils genau an die die beste Wirkung ergebende Stelle gebracht werden können. Außerdem braucht nur mehr der Verdampfer aus gegen hohe Temperaturen unempfindlichem, hochwertigem Material hergestellt zu werden, während der Oberteil aus normalem Baustoff gefertigt sein kann. Schließlich kann durch die eigenärtige Ausbildung des Zündkammereinsatzes der Wärmeübergang vom Verbrennungsraum zur Zündkammer-jeweils auf der für die Sicherheit der Zündung des Gemisches günstigsten Höhe eingestellt und aufrechterhalten werden: Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes im Schnitt veranschaulicht.The special design of the vaporizer results in insertion in the cylinder head base has the advantage that the ignition channels, each exactly to the best effect resulting body can be brought. Besides, just need more the evaporator made of high-quality material that is insensitive to high temperatures to be manufactured, while the upper part can be made of normal building material can. Finally, due to the peculiar design of the ignition chamber insert the heat transfer from the combustion chamber to the ignition chamber - each on the one for safety the ignition of the mixture to be set and maintained at the most favorable level: An exemplary embodiment of the subject matter of the invention is shown in section in the drawing illustrated.

Bei dem Ausführungsbeispiel nach der Abbildung ist der als Verdampfer dienende Unterteil f des Zündkammereinsatzes mit seiner konischen Außenfläche glatt und auf seinen Sitz im Zylinderkopfboden d passend ausgebildet, während der auf den Verdampfer aufgesetzte Oberteil h als Haltemutter dient und in die Zündkammer c ragt, welche oben die Einspritzdüse e aufnimmt.In the embodiment according to the figure, the is as an evaporator serving lower part f of the ignition chamber insert with its conical outer surface smooth and designed to fit on its seat in the cylinder head base d while on The upper part h on the evaporator serves as a retaining nut and into the ignition chamber c protrudes, which receives the injection nozzle e above.

Der Verdampfer f -ist nahe über oder an seinem Boden mit, den Zündkanälen g ver-=sehen, die in den Verbrennungsraum a des Zylinders b münden.The evaporator f -is close above or at its bottom with the ignition channels g = see, which open into the combustion chamber a of the cylinder b.
