Definitions

  • the invention is particularly, even if not exclusively, applied as an ignition system for otto cycle small size two-stroke internal-combustion engines, particularly for motorcycles and mopeds, not excluding its application on small internal-combustion engines destined to other uses, like chain saws, bush mower, mowers, portable generators, etc.
  • Capacitive knocking ignitions and inductive knocking ignitions depending on the use of the stored energy coming from a capacitor or from an inductance.
  • the capacitive knocking ignitions having the possibility of utilizing higher spark currents and high tensions with higher uprisings, are particularly utilized in engines where a good starting isapplicationeed, even if there is the problem of fouling the spark plugs (originated for example, by the presence of oil in the fuel mixture of the two stroke engines).
  • the inductive knocking engines are particularly utilized in the motors in which antipollution norms should be respected, such norms imposing the use of particularly lean air-gasoline mixes, limiting the output of unburnt hydrocarbons.
  • the ideal electronic ignition therefore is the one that, even when disposing of high peak powers and of high tensions with fast uprisings, also keeps high long lasting of sparks.
  • US-A-3 835 830 further describes a method to operate an ignition system with capacitive discharge ignition for internal-combustion engines.
  • the ignition system of US-A-3 835 830 has and utilizes for the capacitive discharge ignition a capacitor means with a thyristor to generate a spark in a correspondent ignition plug and has an electrical energy generating flywheel comprising a feed coil.
  • the ignition system has a secondary winding which has an end electrically connected to the feed coil and an end connected to the ignition plug. The ignition generates a spark on the ignition plug by the discharge of the capacitor means on a primary winding, inducing voltages with high potential on the secondary winding.
  • US,A,4892079 discloses a magnetogenerator having a capacitive plug spark system in which there are no solutions to increment or reinforce the spark time.
  • the Magnetogenerator is however conceived to prevent accidental counterrotation of the engine, using two pick-up pulses in connection with positive and negative current wave.
  • the feeding coil is indicated (obviously in the generators the feeding coils can be more than one and they make part of a stator group around which a flywheel with North-South magnetic sectors turns around, as for example illustrated in the EP-A-305 670 corresponding to the IT-A-83445/87, or even in the version described in IT-A-83393/90, corresponding to WO-A- 91/18 202, in the name of the applicant and of other possible innumerable applicants).
  • the ignition control is supplied by means of a Pick-Up for example according to the solution proposed by the applicant by means of the PCT WO-89/05035, or by means of an electronic elaboration system directly from the feeding coil/s of the applicant IT-A-83417/90 (WO-A- 92/00 453) with the advantageous solution that presents however the inconvenient of a quite short ignition (with all the capacitive knocking ignitions).
  • the diode D1 gets polarized inversely and in this phase having reached a certain potential "Va", the start command is given to the gate (G) of the thyristor, allowing the discharge of the capacitor C1 on the primary winding Lp.
  • Said start command comes from a rotoric position detector that sends electric impulses (P.U.) Fig.1, or directly from the electric energy feed coil/s Ba of said electric energy generator set ( Figures 3-4).
  • the power transmitted to the primary coil (winding) Lp, is transferred to the secondary coil (winding) Ls, to which it is coupled where a high potential is inducted such to start a spark on the ignition plug Ca.
  • the spark current initially flows through D1, polarized now directly by the positive potential induced on the secondary coil Ls, and through the thyristor getting started towards ground.
  • a tension limiter gets in, in parallel to the feed coil/s "Ba"" made for example with a series of zener Dz1, ... Dzn or with a variator or other similar devices preceded by a diode D6 (See Figures..1,3,4) letting this way unaltered the positive half-wave, for the charge of capacitive means (C1) and limiting the negative one to a value not too high , but however higher than the maintenance (sustaining) tension of the "VM” spark in order to guarantee the deriving advantages coming from the circuital solution in object and simultaneously not damaging the electronic components .
  • FIG.3 An example of a concrete application can be made with the circuit of Fig.3 or Fig.4.
  • the second utilizing a inductor-capacitor in reference at IT-A-83393/90 of the applicant and regarding a capacitive knocking ignition system, characterized by the fact that the piloting of the thyristor is carried out on its cathode through a branch with high impedance with the gate of the thyristor electrically connected to ground.
