Description

Verbrennungskraftmaschine mit .im .Kolben vorgesehenem Verbrennungsraum. Es sind Verbrennungskraftmaschinen mit im Kolben vorgesehenem Verbrennungsrauen bekannt geworden. Bei einer solchen bekannten Vorrichtung ist der Düsenteil als Leitkörper für die Kühl- und Verbrennungsluft .ausgebildet und ragt mit einem großen Zwischenraum in den Kolben hinein. Infolge des großen Zwischenraumes zwischen Leitkörper und Wandung des Kolbenhohlraumes wird aber insbesondere in der Nähe des oberen Totpunktes beim Einspritzen des Brennstoffes keine Wirbelung der Verbrennungsluft eintreten können. Eine solche Verbrennungskraftmaschine wird daher nicht ohne Kompressor betrieben werden können, weil . keine ausreichende Mischung von Brennstoff und Luft möglich ist. Der Fort-' fall eines Kompressors ist aber gerade Zweck der* Erfindung. Dies wird gemäß derselben dadurch erreicht, da:B der Verdränger in .den Kolbenhohlraum mit kleinem Spiel hineinragt und dadurch auch in der Nähe des oberen Totpunktes trotz kleiner Kolbengeschwindigkeit einen ausreichenden Luftwirbel und wirksame Mischung des ausgespritzten Brennstoffes erzeugt. Ferner ergibt sich für den durch -die Düse hindurchtretenden BTennstoff eine starke Vorwärmung, da die Düse in der oberen Totpunktlage des Kolbens beim Eintreten .in den Verbrennungsrauen. erwärmt wird. Dieser letzte Umstand tritt insbesondere dann ein, wenn der Brennstoff unmittelbar von der Brcennstoffpumpe in den Verbrennungsraum eingespritzt wird. Diese Vorwärmung ist aber zur Vergasung des Brennstoffes erwünscht. Andererseits wird bei der Vergasung des Brennstoffes und durch die bei der Einspritzung erfolgende Expansion desselben der Brennstoffdüse so viel Wärme entzogen, daß eine Überhitzung derselben nicht stattfindet.Internal combustion engine with a combustion chamber provided in the piston. They are internal combustion engines with combustion grooves provided in the piston known. In such a known device, the nozzle part is as Guide body for the cooling and combustion air. Formed and protruding with a large Interspace into the piston. As a result of the large space between the guide body and the wall of the piston cavity is particularly close to the top dead center No turbulence in the combustion air occurs when the fuel is injected can. Such an internal combustion engine is therefore not operated without a compressor can be because. a sufficient mixture of fuel and air is not possible is. The omission of a compressor is precisely the purpose of the invention. this is achieved according to the same because: B the displacer in .den Piston cavity protrudes with a little play and therefore also near the top dead center a sufficient and effective air vortex despite the low piston speed Mixture of the injected fuel is generated. Furthermore results for the by -The fuel passing through the nozzle requires a lot of preheating because the nozzle is in the Top dead center position of the piston when entering the combustion grooves. warmed up will. This last circumstance occurs especially when the fuel is immediately is injected into the combustion chamber by the fuel pump. This preheating but is desirable for gasifying the fuel. On the other hand, when gassing of the fuel and the expansion of the same during the injection So much heat is withdrawn from the fuel nozzle that it does not overheat takes place.

Die gleichzeitige Anordnung des Verbrennungsraumes im Kolben, die an sich bekannt ist, ermöglicht ferner hierbei, daß zier heiße aus-, der Düse heraustretende Brennstoff bis zum Auftreffen auf die Wandung genügend Zeit hat zu verbrennen, so daß örtliche Überhitzungen der Wandungen und damit Verkrustungen derselben leicht vermieden werden können.The simultaneous arrangement of the combustion chamber in the piston, which is known per se, also allows here that ornamental hot out, the nozzle emerging Fuel has enough time to burn before it hits the wall, so that local overheating of the walls and thus encrustations of the same easily can be avoided.

Der Gegenstand -der Erfindung ist in der Zeichnung in beispielsweiser Ausführung veranschaulicht. Hierin bezeichnet a die Brennstoffeinspritzdüse, welche, wie dargestellt, in der oberen Kolbentotpunktlage in die in dem Kolben b vorgesehene kugelförmig ausgebildete Verbrennahgskammer c hineinragt, also als Verdränger wirkt. Hierdurch wird bewirkt, äaß die in dem Ringraum d des Zylinders e befindliche Luft in der oberen Totpunktlage an der Düse ca vorbei wirbelbildend in die Verbrennungskammer hineinströmt. Der beim Durchtritt durch die Brennstoffdüse vorgewärmte Brennstoffstrahl- wird infolgedessen die Wandung des Verbrennungsraumes nicht in unverbranntem Zustande treffen können.The subject of the invention is shown in the drawing by way of example Demonstrates execution. Here a denotes the fuel injector which, as shown, in the upper dead center position of the piston into the position provided in piston b spherical combustion chamber c protrudes, so it acts as a displacer. This causes the air located in the annular space d of the cylinder e in the top dead center position past the nozzle, creating vortices into the combustion chamber flows in. The fuel jet preheated as it passes through the fuel nozzle as a result, the wall of the combustion chamber is not in an unburned state can meet.
