    摘要: The invention relates to a method for controlling a radio-frequency plasma generator, comprising a supply circuit (2) with a switch (9) controlled by at least one control pulse train, for applying an intermediate voltage (Vinter) at a control frequency on an output to which is connected a resonator (6) for generating a spark between two electrodes (103, 106) when a high voltage level is applied to the output, said method being characterised in that it comprises: receiving first and second measurement signals respectively representative of the operation of a combustion engine and of the type of spark generated; real-time adjusting, based on the received measurement signals, at least one parameter selected from at least the intermediate voltage level, the control frequency and the duration of the control train, in order to promote the branching of the spark generated.

    摘要: The invention relates to a plasma generating device characterised in that it comprises: a supply circuit (2) including a switch (M) controlled by a control signal (V1) for applying an intermediate voltage (Vinter) on an output of the control circuit at a frequency defined by the control signal; a plurality of plasma-generating plug coils (BB1, BB2, BB3, BB4) arranged in parallel on said output via connectors (20), each connector being adapted to be removably connected to a corresponding plug coil and including means (23) adapted for offsetting the resonance frequency of said plug coil so that each plug coil has a distinct resonance frequency; a control device (5) of the supply circuit, that determines the control frequency from the resonance frequencies of the plug coils in order to selectively control the plug coils according to the control frequency used.

    摘要: The invention relates to a spark plug (1) for the internal combustion engine of a motor vehicle, said spark plug being embodied with a generally essentially long shape and comprising: an essentially capacitive lower part (C) provided with two coaxial electrodes, one of said electrodes being a central electrode (3), and a threaded shell (2) for screwing in the plug (1) on the engine; an essentially inductive upper part (I) comprising a central winding (5) provided with a plurality of coils (51) which are wound round a coaxial mandrel (8), an envelope (6), and an insulator (7) which is inserted between the envelope (6) and the winding (5). The essentially capacitive part (C) and the essentially inductive part (I) are mechanically interconnected in such a way as to enable the transmission of a clamping couple applied to the envelope (6) to the essentially capacitive lower part (C). The invention is characterised in that the mandrel (8) can be elastically deformed in such a way as to compensate the effects of the dilation of the insulator (7).
