Abstract
Description
Die
Erfindung geht aus von einer Vorrichtung bzw. einem Verfahren zum
Zünden
einer Brennkraftmaschine nach der Gattung der unabhängigen Patentansprüche. Aus
der
Vorteile der ErfindungAdvantages of invention
Die erfindungsgemäße Vorrichtung bzw. das erfindungsgemäße Verfahren mit den Merkmalen der unabhängigen Patentansprüche hat demgegenüber den Vorteil, dass es die Leistung der einzelnen Hochfrequenzsignale an den Leistungsbedarf bei der Ausbildung eines Hochfrequenzplasmas anpasst. Die entsprechenden Hochfrequenzerzeugungsmittel können somit auf eine geringere mittlere Leistung ausgelegt werden, was die Kosten, die Baugröße und den Kühlbedarf verringern. Weiterhin kann so die Zuverlässigkeit der Hochfrequenzerzeugungsmittel erhöht werden. Als weiterer Vorteil ist zu sehen, dass die im Brennraum angeordneten Zündmittel in Abhängigkeit von der mittleren Leistung des Hochfrequenzplasmas verschleißen. Durch eine verringerte gemittelte Leistung wird somit auch der Verschleiß der im Brennraum angeordneten Zündmittel verringert.The inventive device or the inventive method with the characteristics of the independent claims has the opposite Advantage that it is the power of each high-frequency signals to the power requirement in the formation of a high-frequency plasma adapts. The corresponding high frequency generating means can thus be designed for a lower average power, what the cost, the size and the cooling requirements reduce. Furthermore, so can the reliability of the high-frequency generating means elevated become. Another advantage is that in the combustion chamber arranged ignition dependent on from the average power of the high-frequency plasma wear. By a reduced averaged power will thus also reduce wear in the Combustion chamber arranged ignition reduced.
Weitere Vorteile und Verbesserungen ergeben sich durch die Merkmale der abhängigen Patentansprüche. Da das Hochfrequenzsignal mit hoher Leistung nur für eine sehr geringe Zeitdauer verwendet wird, wird die mittlere Leistung gering gehalten. Eine einfache Signalfolge besteht darin, dass zunächst ein Hochfrequenzsignal hoher Leistung und danach ein Hochfrequenzsignal mit geringerer Leistung verwendet wird. Das Signal mit geringerer Leistung kann aber bereits vor dem Signal mit hoher Leistung vorhanden sein. Um eine sichere Zündung zu gewährleisten, können mehrere Hochfrequenzsignale mit hoher Leistung jeweils gefolgt von Signalen geringer Leistung verwendet werden. Die zeitliche Ansteuerung der Hochfrequenzerzeugungsmittel wird vereinfacht, wenn sich die Signale hoher und geringer Leistung überlappen. Wenn jeweils für die unterschiedlichen Hochfrequenzsignale unterschiedliche Hochfrequenzerzeugungsmittel vorgesehen sind, so können diese jeweils besonders einfach ausgestaltet sein.Further Advantages and improvements result from the characteristics of the dependent Claims. Because the high-frequency signal with high power only for a very low period of time, the average power becomes low held. A simple signal sequence is that first a High-frequency signal of high power and then a high-frequency signal is used at a lower power. The signal with lesser But power can already exist before the signal with high power be. To have a safe ignition to ensure, can several high-frequency signals with high power respectively followed by Low power signals are used. The timing the high frequency generating means is simplified when the High and low power signals overlap. If respectively for the different ones High frequency signals different high frequency generating means are provided, so can each of these be particularly simple.

Alternative kann für die Erzeugung des ersten und zweiten Hochfrequenzsignals auch nur ein einziger Hochfrequenzgenerator vorgesehen werden. Von dem Zeitsteuerglied wird dann ein Leistungssteuerungssignal erzeugt durch das die Leistung des einzigen Hochfrequenzgenerator beeinflusst wird. Ein derartiger einziger Hochfrequenzgenerator mit steuerbarer Leistung ist für sich aufwendiger als jeder der beiden Hochfrequenzgeneratoren für sich. Der Fachmann wird die Lösung auswählen, die das gewünschte Ergebnis zu den günstigsten Kosten bereit stellt.alternative can for the generation of the first and second high-frequency signal only a single high-frequency generator can be provided. From the timer Then, a power control signal is generated by the power the single high frequency generator is affected. Such a single high-frequency generator with controllable power is more expensive in itself as each of the two high frequency generators for themselves. The expert will be the solution select that the wished Result at the best cost ready.
