      a direct-current supply (1),
      at least one spark plug (SP),
      an ignition coil (IC) with a primary winding (L₁) connected to the supply (1) and a secondary winding (L₂) connected to the at least one plug (SP),
      a first electronic switch (S₁) between the primary winding (L₁) of the coil (IC) and the supply (1),
      an inductor (L) between the supply (1) and the primary winding (L₁) of the coil (IC),
      a capacitor (C) in parallel with the circuit branch including the primary winding (L₁) of the coil (IC) and the first electronic switch (S₁),
      a second electronic switch (S₂) between the inductor (L) and the supply (1), and
      an electronic control and operating unit (ECU) arranged to pilot the first and second electronic switches (S₁, S₂) in a first or in a second operative mode in dependence on the signals provided by the sensors (D₁-D n ).
      In the first operative mode, the control unit (ECU) first causes energy to be stored by the inductor (L) and then connects the inductor (L) to the capacitor (C) so as to form a resonance circuit whose energy is discharged into the primary winding (L₁) of the coil (IC) in order to generate a spark. In a second operative mode, the unit (ECU) causes a plurality of cycles to be effected to charge the capacitor (C) so as to increase the voltage across its terminals at each cycle and the capacitor (C) is then discharged into the primary winding (L₁) of the ignition coil (IC) in order to generate the spark.
