Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Glühkerze zur Verwendung in einem Dieselmotor mit einem Glühelement und einem Brennraumdrucksensor nach der Gattung des unabhängigen Patentanspruchs.The invention is based on a glow plug for use in a diesel engine with a glow element and a combustion chamber pressure sensor according to the preamble of the independent claim.
Aus der
Offenbarung der ErfindungDisclosure of the invention
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Glühkerze mit den Merkmalen des Hauptanspruchs weist demgegenüber den Vorteil auf, dass das elektronische Bauelement noch weitere Funktionen hinsichtlich der Ansteuerung des Glühelements aufweist. Insbesondere enthält dieses Bauelement Daten, die zur Ansteuerung des Glühelements verwendet werden. Durch Abspeicherung der jeweils abgeleisteten Betriebsstunden kann eine Alterung der Glühkerze erkannt und durch entsprechende Ansteuermaßnahmen kompensiert werden. Es wird so das elektronische Bauelement mit mehreren Funktionen versehen, insbesondere wird eine Ansteuerung des Glühelements der Glühkerze ermöglicht.In contrast, the glow plug according to the invention with the features of the main claim has the advantage that the electronic component has even more functions with regard to the control of the glow element. In particular, this component contains data that are used to drive the glow element. By storing the respective number of operating hours, aging of the glow plug can be detected and compensated by appropriate control measures. It is thus provided the electronic component with multiple functions, in particular a control of the glow element of the glow plug is possible.
Weitere Vorteile und Verbesserungen ergeben sich durch die Merkmale der abhängigen Patentansprüche. Durch Ansteuerdaten von Glühelementen individueller Glühkerzen können Fertigungsstreuungen oder Alterungserscheinungen von individuellen Glühkerzen durch eine entsprechende Ansteuerung kompensiert werden. Durch die Auswertung von Seriennummern der Glühkerzen kann ein Austausch der Glühkerzen erkannt werden. Durch Angabe eines Glühkerzentyp können standardisierte Ansteuerdaten für diesen Typ von Glühkerzen aus einem weiteren Speicher eines ansteuernden Steuergerätes herangezogen werden. Weiterhin können in dem elektronischen Bauelement Daten zur Auswertung des Brennraumdrucksensors gespeichert werden. Insbesondere können dabei Abgleichsdaten, die nach einer Herstellung der Glühkerze bezüglich der Auswertecharakteristik des Brennraumdrucksensors durch eine Testmessung ermittelt werden, abgespeichert werden. Weiterhin weist die Glühkerze Anschlussstifte auf, durch die eine elektrische Verbindung des elektrischen Bauelements zu einem Steuergerät zur Ansteuerung der Glühkerze bzw. zur Weiterverarbeitung der Messsignale des Brennraumdrucksensors hergestellt werden. Dazu können zwei oder auch nur ein Anschlussstift vorgesehen werden.Further advantages and improvements result from the features of the dependent claims. By control data of the glow elements of individual glow plugs, manufacturing variations or aging phenomena of individual glow plugs can be compensated by a corresponding control. By evaluating the serial numbers of the glow plugs, replacement of the glow plugs can be detected. By specifying a Glühkerzentyp standardized control data for this type of glow plugs from a further memory of a controlling controller can be used. Furthermore, data for evaluating the combustion chamber pressure sensor can be stored in the electronic component. In particular, compensation data that are determined after a production of the glow plug with respect to the evaluation characteristic of the combustion chamber pressure sensor by a test measurement can be stored. Furthermore, the glow plug has connection pins, by means of which an electrical connection of the electrical component to a control device for controlling the glow plug or for further processing of the measurement signals of the combustion chamber pressure sensor is produced. For this purpose, two or only one pin can be provided.
