A device for generating a radiofrequency plasma, that includes a voltage generator, and at least one ignition assembly that includes an ignition plug and a switch provided between a supply terminal of the plug and an output of the generator adapted for electrically connecting the output of the voltage generator to the plug upon reception of a control signal, and an electronic control unit generating the control signal. The electronic control unit measures values representative of evolution in time of the output voltage of the generator. The device further includes a mechanism varying the voltage and/or the frequency of the electric current applied to the supply terminal of the plug based on measured values. The evolution of the generator output voltage is representative of the condition of the plug (new or used).
