Bei warmer Brennkammer besteht dadurch die Gefahr von Frühzündungen oder Teilverbrennungen mit Ruß- oder Koksbildung. Auch kann explosionsartige Verbrennung auftreten, weil der zu früh in die Brennkammer gelangte Brennstoff nach Eintritt der Zündbedingungen plötzlich und. ungeregelt verbrennt.Internal combustion engine or internal combustion ram with a combustion chamber whose opening to the cylinder space is throttled towards the end of the stroke 1) ie l # - 'rtititluug is based on internal combustion Niascli1nen and Brentikraftramm with one Combustion chamber, whose C) opening to the cylinder space is throttled against 1 tul> eti <le, and with an slii-itzscliale, in which liquid fuel is is splashed. Il, -il lx> kautitcn: \ tisfiiliruiigen of this type is the Zyliuderratini <ltircli faithful, changeable upper- str <itnkatial connected with the 13rentikainmer and the 1 # .itisl> scratch shell inside the overflow channel titigeorcltret. Through this: \ tiorder of the injection scliale li_gt tliesellm t @ hren <l of the whole diclitungsliulx # s innerlialli of the air flow to the oil fireplace, so leave no or less burning material is carried away into the: combustion chamber at an early stage. When the combustion chamber is warm, there is a risk of premature ignition or partial burns with soot or coke formation. Explosive combustion can also occur because the fuel that entered the combustion chamber too early suddenly and after the ignition conditions have occurred. burns unregulated.

Diese Nachteile werden erfindungsgemäß dadurch vermieden, daß die Einspritzschale, in welche der Kraftstoff während des Verdichtungshubes eingespritzt wird, an der Zylinderwandung und die Brennkammer im Kolbenboden oder die Einspritzschale iin Kolbenboden und die Brennkammer an der Zylinderwandung angeordnet sind, und zwar die Einspritzschale derart, daß sich in ihr bis kurz vor Beendigung des Verdichtungshubes eine wesentliche Luftströmung nicht ausbilden kann., während gegen Ende des Verdichtungshubes zwischenKolben und Zylinder ein Kanal gebildet wird, durch den hindurch die verdichtete Luft in die Einspritzschale, diese ausspülend, gepreßt wird. Durch die Änordnung der Einspritzschale aUBerhalb der Luftströmung zur Brennkammer bis kurz vor Beendigung des Verdichtungshubes kann der in die Einspritzschale gespritzte Brennstoff nicht -"orzeitig in die Brennkammer mitgerissen werden. Nach der Erfindung sammelt sich in der Brennkammer nur reine Luft, zu der erst gegen Hubende Gemisch. hinzutritt. Es werden daher Frühzündungen leichter vermieden und der Verbrennungsablauf besser geregelt.These disadvantages are avoided according to the invention in that the Injection shell into which the fuel is injected during the compression stroke on the cylinder wall and the combustion chamber in the piston crown or the injection shell iin the piston crown and the combustion chamber the cylinder wall arranged are, namely the injection shell in such a way that it is in it until shortly before completion of the compression stroke can not form a substantial air flow., while towards the end of the compression stroke a channel is formed between the piston and cylinder through which the compressed air enters the injection bowl, flushing it out, is pressed. By arranging the injection bowl outside of the air flow to the combustion chamber until shortly before the end of the compression stroke, the can into the injection shell injected fuel will not - "be drawn into the combustion chamber prematurely the invention collects in the combustion chamber only pure air, to the first against Lifting mixture. join. It is therefore easier to avoid and the combustion process is better regulated.

Die erfindungsgemäße Anordnung der Einspritzschale und: die Gestaltung des Überströmkanals, der erst gegen Ende des Verdichtungshubes gebildet wird, ermöglichen ferner, daß der Kraftstoff durch eine vorzugsweise während der Verbrennungsperiode vom Kolben abgedeckte Einspritzdüse eingespritzt wird. Dadurch ist die Einspritzdüse gegen die heißen Brenngase und den hohen Verdichtungsdruck weitgehend geschützt.The inventive arrangement of the injection shell and: the design of the overflow channel, which is only formed towards the end of the compression stroke Furthermore, that the fuel is carried out by a preferably during the combustion period injected nozzle covered by the piston. This is the injector To a large extent protected against the hot fuel gases and the high compression pressure.

Ausführungsformen nach der Erfindung sind in der Zeichnung beispielsweise dargestellt.Embodiments according to the invention are for example in the drawing shown.

Fig. i ist ein Längsschnitt durch einen hängenden Zylinder, wobei der Kolben gerade den Überströmkanal zu bilden beginnt; Fig. 2 zeigt den gleichen Schnitt und den Kolben in Totpunktlage, wobei der Überströmkanal seitlich angeordnet ist; Fig. 3 zeigt eine ähnliche Ausbildung, wobei die Brennkammer im Zylinderkopf angeordnet ist; Fig. 4 zeigt einen Schnitt durch einen stehenden Zylinder mit zentraler, am Zylinderkopf angeordneter Brennkammer, wobei der Kolben sich nahe dem unteren Totpunkt befirwdet; Fig. 5 zeigt eine andere Ausbildung der Einspritzschale; Fig. 6 zeigt noch eine Ausführungsform mit seitlicher Brennkammer.Fig. I is a longitudinal section through a hanging cylinder, wherein the piston is just beginning to form the transfer channel; Fig. 2 shows the same Section and the piston in dead center position, with the overflow channel arranged laterally is; Fig. 3 shows a similar design, the combustion chamber in the cylinder head is arranged; Fig. 4 shows a section through a standing cylinder with a central, Combustion chamber arranged on the cylinder head, with the piston close to the lower one Dead center; Fig. 5 shows another embodiment of the injection cup; Fig. 6 shows another embodiment with a side combustion chamber.

In allen Figuren ist der Zylinder mit i, der Kolben mit 2, die Brennkammer 'mit 3, die Einspritzschale mit 4., die Einspritzdüse mit 5 bezeichnet, aus der der Brennstoffstrah16 austritt. Die Öffnung zur Brennkammer trägt die Bezeichnung 7, und der L`berströmkanal, der durch den Zylinder i und den Kolben 2 am Hubende gebildet wird, ist mit 8 bezeichnet. Der Ansatzg am Kolben oder am Zylinder bildet im Zusammenwirken mit der Einspritzschale 4 an dem Gegenstück den Überströmkanal B. Nur in Fig. 5 strömt die Luft durch die Bohrungen io hindurch und streicht dabei über den in der Einspritzschale 4 lagernden Brennstoff hinweg, wobei sie ihn durch die Öffnung i i in die Brennkammer 3 mit sich reißt.In all figures, the cylinder with i, the piston with 2, is the combustion chamber 'with 3, the injection shell with 4., the injection nozzle with 5, from the the fuel jet 16 emerges. The opening to the combustion chamber bears the designation 7, and the overflow duct that runs through cylinder i and piston 2 at the end of the stroke is formed is denoted by 8. The approach to the piston or cylinder forms in cooperation with the injection shell 4 on the counterpart the overflow channel B. Only in Fig. 5 does the air flow through the holes io and sweep it over the fuel stored in the injection shell 4, with it through the opening i i in the combustion chamber 3 takes with it.

Die Zersdäubung des Brennstoffes wird verbessert durch Abspritrkanten 12 am Eintritt zur 13rentikammer, 3. Die verschiedenen Ausführungsformen lassen sich auch beliebig für stehende, hängende oder liegende Zylinder anwenden, wenn die eingespritzte Brennstoffmenge in der Einspritzschale .4 genügend haftet oder der Brennstoff in der kurzen Zeit bis zur Bildung des Überströmkanals nicht Zeit hat; aus der Einspritzschale 4 auszutreten. Die Anordnung der Einspritzschale am Kolben setzt voraus, daß der Kraftstoff infolge .der Kolbenverzögerung noch nicht wesentlich aus der Schale austritt, bevor der Ansatz des Zylindenbodens eintaucht, wozu gegebenenfalls die Einspritzung spät erfolgen muß.The atomization of the fuel is improved by spray edges 12 at the entrance to the 13rentikammer, 3. Leave the various embodiments can also be used for standing, hanging or lying cylinders, if the injected fuel quantity adheres sufficiently in the injection cup .4 or the fuel does not have time in the short time until the overflow channel is formed Has; to exit from the injection shell 4. The arrangement of the injection shell on the Piston assumes that the fuel is not yet due to the piston deceleration substantially emerges from the shell before the approach of the cylinder base is immersed, for which purpose the injection may have to take place late.

Um die Brennstoffdüse 5 der Verbrennung nicht auszusetzen, ist sie durchweg so eingezeichnet, daB sie durch den Kolben -von dem Arbeitsraum während einer gewissen Zeit abgetrennt wird. Sie kann jedoch auch aus baulichen Gründen am Zylinderkopf oder bei Gestaltung nach Fig. 4 auch in der Brennkammer selbst angeordnet sein. Sie ist dann allerdings den hohen Drücken und Temperaturen der Verbrennung stärker ausgesetzt als hei der gezeichneten Anordnung.In order not to expose the fuel nozzle 5 to combustion, it is consistently drawn in such a way that they pass through the piston -from the working space during is disconnected after a certain period of time. However, it can also be used for structural reasons arranged on the cylinder head or in the configuration according to FIG. 4 in the combustion chamber itself be. It is then however the high pressures and temperatures of the combustion more exposed than in the arrangement shown.

Die Wirkungsweise ist folgende: Während des Verdichtungshubes wird der Brennstoff im wesentlichen unzerstäubt in die Einspritzschale .4 eingespritzt. Dabei erwärmt sich. der Brennstoff je-nach dem Wärmezustand der Schale und wird gegebenenfalls auch zum Teil vergasen. ,Da in der Einspritzschale 4 vorerst keine wesentliche Luftbewegung vorhanden ist, bleibt das Gas in der Einspritzschale und mischt sich nur wenig mit der Luft. Die Vermischung erfolgt erst am jEnde der Verdichtung durch das Überströmender aus dem Zylinderraum verdrängten Luft, die dann auch die Zylinderraum Selbstzündung erforderliche Temperatur hat. Eine wirksame Luftgeschwindigkeit wird dabei durch Verengung der Verbindungswege zwischen Zylinderraum und Brennkammer erzeugt. Die heiße und innig mit dem vergasten oder nebelförmigen Brennstoff gemischte Luft bildet ein zündfähiges Gemisch, das in der Brennkammer iverbren.nt und dann, auf dem umgekehrten Wege unter weiterer Vermischung in den Zylinderraum zurückströmt.The mode of operation is as follows: During the compression stroke the fuel is injected into the injection shell .4 in essentially non-atomized form. This warms up. the fuel depending on the heat state of the shell and will possibly also partially gasify. Since there are initially no If there is substantial air movement, the gas will remain in the injection cup and mixes little with the air. The mixing only takes place at the end of the compaction the air displaced from the cylinder space by the overflow, which then also the Cylinder chamber has auto-ignition temperature required. An effective air speed is achieved by narrowing the connecting paths between the cylinder space and the combustion chamber generated. The hot and intimately mixed with the gasified or foggy fuel Air forms an ignitable mixture that burns in the combustion chamber and then, flows back into the cylinder chamber in the opposite direction with further mixing.

Fremdzündung oder die Anordnung eines Glühkörpers, der z. B'. beim Anlassen elektrisch aufgeheizt wird, kann zum Anlassen oder zur Anpassung an schwer zündende Brennstoffe oder zur Herabsetzung der Verdichtung erwünscht sein. Der Glühkörper kann dann bei Ausgestaltung nach F ig. 3, 4 und 6 in der Öffnung 7 zur Brennkammer 3 so angeordnet werden, daß Frühzündungen nicht eintreten.External ignition or the arrangement of an incandescent body that z. B '. at the Starting is electrically heated, can be used for starting or adapting to difficult igniting fuels or to reduce compression may be desirable. The incandescent body can then with the configuration according to F ig. 3, 4 and 6 in the opening 7 to the combustion chamber 3 are arranged so that pre-ignition does not occur.
