Abstract
Description
Die Erfindung betrifft eine Kraftstoffeinspritzeinheit eines insbesondere selbstzündenden Hubkolbenmotors mit einer Einspritzdüse.The The invention relates to a fuel injection unit of a particular self-igniting Reciprocating engine with an injection nozzle.
Die DE-A-101 44 692 zeigt eine Befestigungsanordnung für Pumpe-Düse-Element im Zylinderkopf eines Verbrennungsmotors, wobei in den Zylinderkopf neben dem Pumpe-Düse-Element in den Brennraum reichendes Heizelement, in der Art eines Glühstifts eingeschraubt ist.The DE-A-101 44 692 shows a mounting arrangement for the pump-nozzle element in the cylinder head of an internal combustion engine, being in the cylinder head next to the pump-nozzle element in the combustion chamber reaching heating element, in the manner of a glow plug is screwed.
Das der Erfindung zugrunde liegende Problem wird darin gesehen, dass eine derartige Anordnung einen großen Bauraum benötigt.The The problem underlying the invention is seen in that Such an arrangement requires a large amount of space.
Dieses Problem wird erfindungsgemäß durch die Lehre des Patentanspruchs 1 gelöst, wobei in den weiteren Patentansprüchen Merkmale aufgeführt sind, die die Lösung in vorteilhafter Weise weiterentwickeln.This Problem is inventively solved the teaching of claim 1, wherein in the other claims features listed are the solution develop in an advantageous manner.
Auf diese Weise wird eine Kraftstoffeinspritzeinheit zur Verfügung gestellt, welche ein integriertes Heizelement aufweist, wodurch das Heizelement keinen Bauraum benötigt bzw. für das Heizelement keine separate Aussparung in dem Zylinderkopf des Verbrennungsmotors vorgesehen werden muss. Bei einer derartigen Kraftstoffeinspritzeinheit kann es sich beispielsweise um eine kraftstoffdruckgesteuerte Standardeinspritzeinheit, eine nebenwellengesteuerte, mechanische Kraftstoffeinspritzeinheit, eine elektronische Kraftstoffeinspritzeinheit oder auch eine eine Hochdruckpumpe aufweisende Kraftstoffeinspritzpumpe handeln.On this way, a fuel injection unit is provided, which has an integrated heating element, whereby the heating element no Space required or for the heating element no separate recess in the cylinder head of the internal combustion engine must be provided. In such a fuel injection unit For example, it may be a fuel pressure controlled standard injection unit. a side-wave controlled mechanical fuel injection unit, an electronic fuel injection unit or a Act high pressure pump having fuel injection pump.
Es ist denkbar, dass das Heizelement beispielsweise in einen Korpus der Kraftstoffeinspritzeinrichtung integriert ist und/oder von der Einspritzdüse beabstandet vorgesehen ist. Eine optimale Erfüllung der Heizfunktion wird aber erfüllt, wenn das Heizelement in der Umgebung der und/oder angrenzend an die Einspritzdüse angeordnet ist.It It is conceivable that the heating element, for example, in a body the fuel injection device is integrated and / or of the injection is provided spaced. An optimal fulfillment of the heating function is but fulfilled, when the heating element is in the vicinity of and / or adjacent to the injector is arranged.
Das Heizelement kann beispielsweise im Wesentlichen punktförmig, beispielsweise in der Art einer konventionellen Heizeinrichtung, ausgebildet sein oder durch mehrere unabhängige oder abhängig beheizte Heizelemente gebildet werden. Eine besonders gleichmäßige Erwärmung ergibt sich aber, wenn das Heizelement die Einspritzdüse zumindest im Wesentlichen ringförmig umgibt. Dieser Ring kann einteilig oder mehrteilig, geschlossen oder auch unterbrochen ausgebildet sein. Es ist auch eine quadratische, dreieckige oder jede andere geeignete, an die jeweiligen Einsatzbedingungen angepasste Ausbildung des Heizelements denkbar.The Heating element, for example, substantially punctiform, for example in the manner of a conventional heater may be formed or by several independent ones or depending on heated Heating elements are formed. A particularly uniform heating results but if the heating element, the injection nozzle at least substantially annular surrounds. This ring can be one-piece or multi-piece, closed or be formed interrupted. It is also a square, triangular or any other suitable, to the particular conditions of use adapted design of the heating element conceivable.
Das Heizelement und die Einspritzdüse können direkt aneinander angrenzend vorgesehen sein. Es ist aber auch möglich, dass zwischen dem Heizelement und der Einspritzdüse wenigstens eine Isolationseinrichtung vorgesehen ist.The Heating element and the injector can be provided directly adjacent to each other. But it is also possible that between the heating element and the injection nozzle at least one isolation device is provided.
Eine derartige Isolationseinrichtung kann beispielsweise in der Art einer Hülse aus einem vorzugsweise thermisch isolierenden Material, beispielsweise Keramik ausgebildet sein. Es ist aber auch denkbar, dass zwischen dem Heizelement und der Einspritzdüse ein Spalt bzw. ein Luftspalt vorgesehen ist, der eine insbesondere thermisch isolierende Wirkung aufweist und die Isolationseinrichtung bilden kann.A Such isolation device may, for example, in the manner of a Sleeve off a preferably thermally insulating material, for example Ceramic be formed. But it is also conceivable that between the heating element and the injection nozzle, a gap or an air gap is provided, which has a particular thermal insulating effect and can form the isolation device.
Das Heizelement kann in jeder geeigneten Art und Weise insbesondere aber in der Art eines Widerstands-, Induktions- oder Halogenheizelements und/oder eines Glühelements ausgebildet sein und kann beispielsweise ein keramisches, vitrokeramisches oder auch ein Stahlgehäuse aufweisen.The Heating element can in any suitable manner in particular but in the manner of a resistance, induction or Halogenheizelements and / or a glow element be formed and can, for example, a ceramic, vitroceramic or a steel case exhibit.
