Brennstoffeinspritzventll-Zündkerze-Kombination Brennstoffeinspritzventll-spark plug combination
Stand der TechnikState of the art
Die Erfindung geht aus von einer Brennstoffemspritzventil - Zündkerze -Kombination nach der Gattung des Hauptanspruchs.The invention relates to a fuel injection valve - spark plug combination according to the preamble of the main claim.
Aus der EP 0 661 446 AI ist ein Brennstoffemspritzventil mit einer integrierten Zündkerze bekannt Das Brennstoffemspritzventil mit integrierter Z ndkerze dient zum direkten Einspritzen von Brennstoff den Brennraum einer Brennkraftmaschine und zum Zünden des m den Brennraum eingespritzten Brennstoffs Durch die kompakte Integration eines Brennstoffeinspritzventils mit einer Zündkerze kann E bauraum am Zylinderkopf der Brennkraftmaschine eingespart werden. Das bekannte Brennstoffemspritzventil mit integrierter Zündkerze weist einen Ventilkorper auf, der zusammen mit einem mittels einer Ventilnadel betatigbaren Ventilschließkorper einen Dichtsitz bildet, an welchen sich eine an einer dem Brennraum zugewandten Stirnflache des Vent ilkorpers ausmundende Abspritzoffnung anschließt Der Ventilkorper ist durch einen keramischen Isolationskorper von einem m den Zylinderkopf der Brennkraftmaschine einschraubbaren Gehausekorper hochspannungsfest isoliert. An dem Gehausekorper befindet sich eine Masseelektrode, um ein Gegenpotential zu dem mit Hochspannung beaufschlagten Ventilkorper zu bilden Bei Beaufschlagung des Vent ilkorpers mit einer ausreichenden Hochspannung erfolgt ein Funkenύberschlag zwischen dem Ventilkorper und der mit dem Gehausekorper verbundenen Masseelektrode.A fuel injection valve with an integrated spark plug is known from EP 0 661 446 AI. The fuel injection valve with an integrated spark plug is used for the direct injection of fuel into the combustion chamber of an internal combustion engine and for igniting the fuel injected into the combustion chamber. The compact integration of a fuel injection valve with a spark plug can E space can be saved on the cylinder head of the internal combustion engine. The known fuel injection valve with an integrated spark plug has a valve body which, together with a valve closing body which can be actuated by means of a valve needle, forms a sealing seat, to which a spray opening opening at an end face of the valve body facing the combustion chamber connects. The valve body is made of a m by a ceramic insulation body the cylinder head of the internal combustion engine screw-in housing body is insulated against high voltage. A ground electrode is located on the housing body in order to form a counter potential to the valve body to which high voltage is applied when the valve body is acted on with sufficient high voltage, a sparkover occurs between the valve body and the ground electrode connected to the housing body.
Bei dem bekannten Brennstoffemspritzventil mit integrierter Zündkerze ist jedoch nachteilig, daß die Position des Funkenuberschlags bezuglich des von der Abspritzoffnung abgespritzten BrennstoffStrahls nicht definiert ist, da der Funkenuberschlag an einer nahezu beliebigen Stelle im seitlichen Bereich eines Vorsprungs des Ventilkόrpers erfolgen kann. Eine sichere Zündung der sogenannten Strahlwurzel des von der Abspntzöffnung abgespritzten BrennstoffStrahls ist bei dieser bekannten Bauweise nicht mit der notwendigen Sicherheit möglich. Eine sichere und zeitlich exakt definierte Entflammung des BrennstoffStrahls ist jedoch für eine Schadstoffreduzierung unbedingt erforderlich. Ferner kann an der Austrittsöffnung des BrennstoffStrahls eine stetig fortschreitende Verrußung oder Verkokung auftreten, die die abgespritzte Strahlform beeinflußt.In the known fuel injection valve with an integrated spark plug, however, it is disadvantageous that the position of the spark flash is not defined with respect to the fuel jet sprayed from the spray opening, since the spark flash can take place at almost any point in the lateral region of a projection of the valve body. A reliable ignition of the so-called jet root of the fuel jet sprayed from the bracing opening is not possible with the necessary certainty in this known construction. However, a safe and precisely defined ignition of the fuel jet is absolutely necessary to reduce pollutants. Furthermore, a progressively sooting or coking can occur at the outlet opening of the fuel jet, which affects the sprayed jet shape.

Advantageously, the candle stone is secured by a screw sleeve, a clamping ring or a suitable form of plastic sheathing of the fuel injection valve in its receiving bore. The candle stone is screwed or inserted into the respective holder
Besonders vorteilhaft ist die Neigung der Längsachse desThe inclination of the longitudinal axis of the
Kerzensteins gegenüber der Langsachse der Ventilnadel, da ein direktes Anspritzen der Zündkerze durch das Brennstoffemspritzventil vermieden werden kann.Candle stones opposite the longitudinal axis of the valve needle, since a direct injection of the spark plug by the fuel injection valve can be avoided.
Ein weiterer Vorteil liegt darin, daß die Funkenlage naher an die Düse herangefunrt werden kann (im Vergleich zur parallelen Achsenanordnung) Damit wird ein ungedrosselter Leerlaufbetrieb möglichAnother advantage is that the spark position can be closer to the nozzle (compared to the parallel axis arrangement). This enables unrestricted idling
Weiterhin ist . von Vorteil, daß die Zündkerze und die Masseelektrode der Zündkerze jeweils unabhängig vom Brennstoffemspritzventil austauschbar sind.Still is. It is advantageous that the spark plug and the ground electrode of the spark plug can each be replaced independently of the fuel injection valve.
