Abstract
Description
Die Erfindung bezieht sich auf eine Hubkolbenbrennkraftmaschine mit einem Kurbelgehäuse, in dem zumindest ein Zylinder mit einem Kolben angeordnet ist, wobei der Kolben mit einer im Kurbelgehäuse gelagerten Kurbelwelle mittels eines Pleuels in Wirkverbindung steht, mit einem den Zylinder abdeckenden Zylinderkopf, in dem zumindest ein Einspritzventil mit einer Einspritzdüse und einem Einspritzdüsenhalter in einer Stufenöffnung im Zylinderkopf eingebaut ist, wobei der dem Kolben zugewandte Endbereich des Einspritzventils mittels eines Absatzes und Zwischenschaltung eines Dichtsitzes an der Stufe unter Druckbelastung abgedichtet ist und wobei die Druckkraft durch ein Spannelement zwischen dem Einspritzdüsenhalter und dem Zylinderkopf dargestellt ist.The The invention relates to a reciprocating internal combustion engine with a Crankcase in which at least one cylinder with a Piston is arranged, the piston with a in the crankcase stored crankshaft is in operative connection by means of a connecting rod, with a cylinder head covering the cylinder, in which at least an injection valve with an injection nozzle and an injection nozzle holder is installed in a stepped opening in the cylinder head, wherein the piston end region of the injection valve by means of a paragraph and interposition of a sealing seat at the stage is sealed under pressure load and wherein the pressure force by a tensioning element between the injection nozzle holder and the cylinder head is shown.
Eine
derartige Hubkolbenbrennkraftmaschine ist aus dem
Aufgabe der Erfindung ist es daher, eine gattungsbildende Hubkolbenbrennkraftmaschine dahingehend zu verbessern, dass bei Qualitätsmängeln der Verschraubung zwischen Einspritzdüse und Einspritzdüsenhalter mit Sicherheit das Austreten von Kraftstoff aus der Brennkraftmaschine mit den zuvor geschilderten Problemen und Nachteilen vermieden wird.task The invention is therefore a generic reciprocating internal combustion engine to improve that in case of quality defects of the Screw connection between injector and injector holder with certainty the escape of fuel from the internal combustion engine avoided with the problems and disadvantages described above.
Die Aufgabe der Erfindung wird dadurch gelöst, dass der Einspritzdüsenhalter im Zylinderkopf abgedichtet ist und dass zwischen dem Dichtsitz und der Abdichtung des Einspritzdüsenhalters im Zylinderkopf an der Stufenöffnung ein Ablaufkanal angeschlossen ist. Dadurch wird erreicht, dass durch Undichtheit austretender Kraftstoff nicht nach Außen dringt, sondern in den Ablaufkanal gelangt und dort sicher abgeführt werden kann.The The object of the invention is achieved in that the injection nozzle holder is sealed in the cylinder head and that between the sealing seat and the seal of the injector holder in the cylinder head at the step opening a drainage channel is connected. This ensures that leakage through leaking fuel does not penetrate to the outside, but enters the drainage channel and can be safely removed there.
Liegt wie bei der gattungsgemäßen Ausgestaltung zwecks Luftkühlung des Zylinderkopfes ein Freiraum zwischen einer Brennraumplatte und einer abgewandten Platte am Zylinderkopf vor, so kann die Stufenöffnung beispielsweise durch ein eingesetztes Rohr hergestellt werden, an das der Ablaufkanal angeschlossen ist. Handelt es sich bei der Stufenöffnung um eine Stufenbohrung, die im Vollmaterial des Zylinderkopfes eingearbeitet ist, so kann der Ablaufkanal direkt daran angeschlossen werden. In vorteilhafter Weise steht der Ablaufkanal mit dem Kurbelgehäuse der Hubkolbenbrennkraftmaschine in Verbindung. Da es sich bei dem Überlauf normalerweise nur um eine geringe Menge Kraftstoff handelt, ist es unschädlich, dass dieser Kraftstoff in den Ölhaushalt der Hubkolbenbrennkraftmaschine gelangt, da dieser Kraftstoff in Warmbetrieb der Brennkraftmaschine ohne Nachteile verdampfen kann. Im Übrigen handelt es sich um Dieselkraftstoff, der eine Schmierwirkung hat.Lies as in the generic embodiment in order Air cooling the cylinder head a clearance between one Combustion chamber plate and a remote plate on the cylinder head, Thus, the step opening, for example, by an inserted pipe be manufactured, to which the drainage channel is connected. These it is the step opening to a stepped bore, the is incorporated in the solid material of the cylinder head, so can the Flow channel can be connected directly to it. In an advantageous manner Way is the flow channel with the crankcase of the reciprocating internal combustion engine in connection. Since the overflow is usually only is a small amount of fuel, it is harmless that this fuel is in the oil budget of the reciprocating internal combustion engine arrives, because this fuel in warm operation of the internal combustion engine without Can evaporate disadvantages. Incidentally, it is about Diesel fuel that has a lubricating effect.
In vorteilhafter Weise steht der Ablaufkanal mit einem Zwischenraum in Verbindung, der seinerseits mit einem dem Zylinderkopf benachbarten Raum für Betätigungselemente und Federn von Gaswechselventilen in Verbindung steht. Dadurch braucht keine eigene Verbindung geschaffen zu werden, da der Raum mit den Gaswechselventilen üblicherweise einen Rücklauf in das Kurbelgehäuse der Brennkraftmaschine, zum Beispiel über Stoßstangenbohrungen, aufweist.In Advantageously, the drainage channel is with a gap in turn, in turn, with a space adjacent to the cylinder head for actuators and springs of gas exchange valves communicates. As a result, does not need to create its own connection to become, since the space with the gas exchange valves usually a return to the crankcase of the internal combustion engine, for example, via bumper holes, has.
Der Zwischenraum kann sich bei einem Zylinderkopf für mehrere Zylinder, beispielsweise ein Blockzylinderkopf, entlang des Zylinderkopfes erstrecken und an einem Ende in den Ventilraum austreten. Der Ablaufkanal ist oberhalb der Verschraubung der Einspritzdüse, vom Kolben aus gesehen an der Stufenöffnung, angeordnet. Dadurch wird erreicht, dass der Raum zwischen Einspritzdüse und Einspritzdüsenhalter sich mit Kraftstoff oder auch mit Öl aus dem Raum der Gaswechselventile füllen kann, wenn auch der Zwischenraum hoch genug angeordnet ist, so dass bei extremem Motorbetrieb in chemisch aggressiver Umgebung (zum Beispiel in Salzbergwerken und Nickelminen) Korrosion an den Einspritzdüsen oder Einspritzdüsenhalter sowie der Stufenöffnung vermieden wird.Of the Interspace may vary for one cylinder head Cylinder, for example a block cylinder head, along the cylinder head extend and exit at one end in the valve chamber. The drainage channel is above the screw connection of the injector, from the piston seen from the step opening, arranged. This will achieved that the space between injector and injector holder with fuel or with oil from the space of the gas exchange valves can fill, even if the gap is arranged high enough is, allowing for extreme engine operation in chemically aggressive environments (for example in salt mines and nickel mines) corrosion at the Injectors or injector holder as well the step opening is avoided.
In vorteilhafter Weise ist das Spannelement als Kronenmutter ausgebildet, die sich am Einspritzdüsenhalter, vorzugsweise unter Zwischenschaltung eines Federrings, und an einem Gewinde in der Stufenöffnung abstützt. Dabei ist zwischen Kronenmutter und Einspritzdüsenhalter ein Dichtring vorgesehen, so dass eine Abdichtung zwischen Düsenhalter und Kronenmutter gegeben ist. Eine Abdichtung im Gewinde zwischen Kronenmutter und Stufenbohrung kann durch Dichtmittel, vorzugsweise elastisches Dichtmittel, erfolgen.Advantageously, the clamping element is designed as a castle nut, which is supported on the injection nozzle holder, preferably with the interposition of a spring ring, and on a thread in the step opening. In this case, a sealing ring is provided between the castle nut and injector holder, so that a seal between the nozzle holder and the crown nut is given. A seal in the thread between the castle nut and stepped bore can be done by sealant, preferably elastic sealant.
Zur weiteren Erläuterung der Erfindung wird auf die Zeichnung verwiesen, in der ein Ausführungsbeispiel der Erfindung vereinfacht dargestellt ist. Die einzige Figur zeigt einen Schnitt durch einen Zylinderkopf mit Ablaufkanal.to Further explanation of the invention is based on the drawing referenced, in which an embodiment of the invention is shown simplified. The single figure shows a section through a cylinder head with drainage channel.
