DISPOSITIVO DE IGNIÇÃO POR MICROONDAS, E, MÉTODO PARA DIAGNOSTICAR UM ESTADO DE SUJEIRA DOS ELETRODOS DE IGNIÇÃO |
摘要 |
A radiofrequency ignition device including: a control capable of generating an ignition control signal; a supply circuit controlled by the ignition control signal for applying a supply voltage on an output interface of the supply circuit at a frequency defined by the control signal; at least one plasma generation resonator connected on an output interface of the supply circuit and capable of generating a spark between two ignition electrodes of the resonator upon an ignition control; a mechanism measuring an electric parameter representative of a variation in a supply voltage of the resonator; and a module determining the fouling condition of the electrodes based on the measured electric parameter and on a predetermined reference value. |
