Description

Brennkraftmaschine mit Brennstoffeinspritzung und Selbstzündung Die Erfindung bezieht sich auf eine Brennkraftmaschine mit Brennstoffeinspritzung und Selbstzündung, deren Verdichtungsraum aus dem eigentlichen Zylinderraum und einem damit durch mindestens eine enge Öffnung verbundenen Kammerraum besteht, dessen Wände als Einsatzstück in einem den Zylinderraum umschließenden Leichtmetallgußteil t Zylinderdeckel, Zylindermantel oder Kolben) eingegossen sind.Internal combustion engine with fuel injection and compression ignition The invention relates to an internal combustion engine with fuel injection and Auto-ignition, whose compression chamber consists of the actual cylinder chamber and a therewith connected by at least one narrow opening chamber space, whose Walls as an insert in a light metal casting enclosing the cylinder space t cylinder cover, cylinder jacket or piston) are cast in.

Gemäß der Erfindung bestehen die eingegossenen Wandteile aus einer den Boden und die Seitenwände der Kammer bildenden Glocke und einem die enge Öffnung enthaltenden Mündungsstück, das den Kammerdeckel bildet und mit dem Rand der Glocke verbunden ist. Die derart zusammengesetzten Stücke der eingegossenen Wandteile sind leicht herzustellen. Man kann dabei auch für die den Trichter umschließenden Wandteile widerstandsfähigeres Material wählen als für die in vielen Fällen weniger stark beanspruchte flocke.According to the invention, the cast wall parts consist of a the bottom and the side walls of the chamber forming a bell and a narrow opening containing mouthpiece that forms the chamber lid and with the edge of the bell connected is. The so assembled pieces of the cast wall parts are easy to manufacture. You can also do this for the wall parts surrounding the funnel Choose more resistant material than for the in many cases less strong claimed flake.

Auf der Zeichnung sind zwei Ausführungsi,eispiele des Erfindungsgegenstandes jeweils im Längsschnitt durch Zylinder und Kolben dargestellt.On the drawing are two Ausführungsi, examples of the subject of the invention each shown in longitudinal section through cylinder and piston.

Die Abb. i zeigt ein Ausführungsbeispiel, bei dem der Mischraum und der Kammerraum im Kolben angeordnet sind.Fig. I shows an embodiment in which the mixing space and the chamber space are arranged in the piston.

Abb. 2 veranschaulicht das zweite Ausführungsbeispiel. Der Mischraum und die Kammer sind dabei im Zylinderdeckel untergebracht.Fig. 2 illustrates the second embodiment. The mixing room and the chamber are housed in the cylinder cover.

In Abb. i ist der Zylinder mit a, der Zylinderdeckel mit b, der aus Leichtmetall gegossene Kolben mit c und der von diesen Teilen umschlossene Zylinderraum mit d bezeichnet. Der Zylinderraum bildet zusammen mit einem trichterförmigen Mischraum e und einem Kammerraum f den Verdichtungsraum. Die Räume e und f sind im Kolben angeordnet und durch eine enge Öffnung g miteinander verbunden. Der Brennstoff wird in der Nähe der inneren T otlage durch eine Düse i in den Mischraum e gespritzt.In Fig. I the cylinder is marked with a, the cylinder cover with b, the piston cast from light metal with c and the cylinder space enclosed by these parts with d. The cylinder space forms the compression space together with a funnel-shaped mixing space e and a chamber space f. The spaces e and f are arranged in the piston and connected to one another by a narrow opening g. The fuel is in the vicinity of the inner T plight sprayed through a nozzle into the mixing space i e.

Die Wände der im Kolben untergebrachten Räume e und f werden durch Einsatzstücke h und k gebildet, die in den Leichtmetallgußkolben a eingegossen sind und aus Gußeisen, Stahl, Bronze oder einem ähnlichen widerstandsfähigeren Werkstoff als Leichtmetall bestehen.The walls of the spaces e and f accommodated in the piston are formed by insert pieces h and k which are cast in the light metal cast piston a and are made of cast iron, steel, bronze or a similar more resistant material than light metal.

Das Einsatzstück k ist eine glockenförmige Schale und bildet den Boden und die Seitenwände der Kammer. Es ist an seinem Rand m mit dem den Kammerdeckel und die Trichterraumwände bildenden Einsatz- oder Mündungsstück h verschraubt. Der Rand m der aus Blech gedrückten Schale sticht über die Verschraubung hinaus noch ein Stück in die Gußwand des Kolbens hinein, so daß er umgossen wird und die Schale dadurch sicher festhält. Eine im Kolben befestigte Trennwand n schafft unter der Außenwand der Kammer f einen Luftisolierraum und verhindert überdies, daß Öl an die heiße Kammerwand spritzen, daran verkoken und dann als Ölkohle wieder in die Triebteile gelangen kann.The insert k is a bell-shaped shell and forms the bottom and the side walls of the chamber. It is at its edge m with the chamber lid and the insert or mouth piece h forming the funnel space walls is screwed. Of the Edge m of the shell pressed from sheet metal still protrudes beyond the screw connection a piece into the cast wall of the piston, so that it is poured over and the shell thereby securely holds on. A partition wall n fixed in the piston creates an air insulation space under the outer wall of the chamber f and also prevents that oil splash on the hot chamber wall, coke on it and then again as oil carbon can get into the drive parts.

Die beschriebene Bauart hat den Vorteil, daß beim Gießen ein Kern für die Kammer f, der durch die enge Öffnung g nur schwer entfernt werden könnte, nicht nötig ist, weil die Form der Kammerinnenwände schon vor dem Guß festliegt.The type of construction described has the advantage that a core during casting for the chamber f, which could only be removed with difficulty through the narrow opening g, is not necessary because the shape of the inner walls of the chamber is already fixed before casting.

Beim zweiten Beispiel nach Abb. 2 ist dieser Vorteil ebenfalls ausgenutzt. Es unterscheidet sich vom Beispiel nach Abb. r hauptsächlich dadurch, daß die Kammer im Zylinderdeckel angeordnet ist. Überdies ist dabei eine elektrisch beheizte Glühdrahtkerze o im Zylinderdeckel untergebracht, deren Glühschleife in den Mischraum e hineinragt.In the second example according to Fig. 2, this advantage is also used. It differs from the example in Fig. R mainly in that the chamber is arranged in the cylinder cover. There is also an electrically heated glow wire plug o housed in the cylinder cover, the glow loop of which protrudes into the mixing chamber e.

Die Außenwand der Kammer kann wie bei den Ausführungsbeispielen von einer abgeschlossenen Luftisolierschicht umgeben sein, sie kann aber auch, falls Bedarf vorliegt, mit Luft oder Wasser gekühlt werden.The outer wall of the chamber can, as in the embodiments of FIG be surrounded by a closed air insulation layer, but it can also, if If there is a need, it can be cooled with air or water.
