Method for controlling an ignition device and ignition device corona corona

摘要

Method for controlling an ignition device and ignition device corona corona.The present invention provides a method for controlling ignition device corona electrode, which comprises a plug (5) in which a corona discharge u00e9u00a0produzida,A resonant circuit (7) which contains ignition electrode (5) and a generator of high frequency (100 connected to the resonant circuit (7), where the resonant circuit (7) is excited with AC voltage produced by the generator of high frequency (10).Au00a0frequ00fcu00eancia of this voltage being specified by a control signal (UD) applied through the high frequency generator (10) the frequency of the control signal (UD) sendou00a0alterado as a control variable of a control circuit and au00a0posiu00e7u00e3o phase between the current (II) F. Lui in the resonant circuit (7) and a voltage signal is regulated to a target value.Characterized by the fact that the target value to be changed during the operation of the ignition device corona. An ignition device for igniting fuel in a corona chamber of fuel in an internal combustion engine is also described.
