Definitions

  • the invention relates to an ignition device for internal combustion engines and other work machines excited by spark ignition with an energy source having an ignition coil or ignition transformer.
  • capacitors are advantageously used in parallel with the ignition sparks and arcing paths to ground in order to improve the ignition.
  • the circuit has the disadvantage of an excessively slow voltage rise. This is due to the impedance of the long current path, because it is difficult to carry a high-frequency current signal over a more branched casting (engine block).
  • the charging and discharging process is carried out via a current path or series resonant circuit.
  • this disadvantage is eliminated in that the ignition coil or ignition transformer is replaced by a pulse oscillator ignition.
  • parallel to A capacitor is arranged on the primary and secondary side.
  • charging and discharging takes place via separate cable routing, with the charging current of the capacitor being fed back and inducing a much higher voltage across the secondary side via the primary side.
  • a correspondingly dimensioned attenuator is also arranged in the circuit according to the invention, which allows the ignition current to be extended in favor of time.
  • the capacitor according to the invention does not directly bridge the spark gap, but the circuit closes via the primary electrolytic capacitor of the ignition coil or via the vehicle electrical system (battery).
  • this is achieved in that the primary side of the ignition coil is acted upon by the charging current of the capacitor lying in parallel to the primary and secondary sides with a negative current potential which accelerates the magnetic field breakdown and thus a higher voltage is induced secondarily. This process is repeated until an overturn occurs on the respective discharge route or routes.
  • a tunable voice coil 19 must be provided parallel to the primary winding 5 of the pulse oscillator. With the spark plug tuning plug, the impedance of the spark plug of the ignition system is adjusted.
  • the capacitor 32 is charged from point 29 via line 31 and line 2 via point 16 and line 15 to the ignition lock to the battery.
  • the control device contacts
  • line 34 the negative side of the capacitor 32 is led via line 31 point 30, line 33 via the switching unit 35 and line 8 to the connection points 20 and 36 of the coils 19 and 5 .
  • line 3 leads the current back via point 17 and line 15 and point 16 with line 2 to the positive plate of capacitor 32.
  • a magnetic field is built up in the cores 10 and 21 by the current flow in the coils 5 and 19.
  • the charging current is interrupted, the magnetic field in both cores begins to collapse.
  • an oppositely directed voltage builds up in the coils 5, 19 and 22.
  • point 23 of line 25 and point 24 with line 9 charge capacitor 7.
  • the current flowing in the opposite direction via line 6, point 1, line 2, point 16 and line 15 at point 17 via line 3 at points 4 and 18, now causes an accelerated field breakdown in the cores 10 and 21 Tension increased.
  • the breakdown voltage is reached at the cathode 26 via line 25, a high-energy arc is formed, which in turn charges the capacitor 12 via anode 27, point 28, line 13.
  • connection point 44 of the plug adapter plug 50, via the winding 45, connection point 46 ensures that the arc is maintained on the candle with the highest energy flowing current is in turn braked by an oppositely directed voltage, which is influenced in this way by the core 48 in the carrier 47 ssen that the current simultaneously from the coatings of the capacitors 12 and 7 and the coil 22 via ground 29, line 31, capacitor 32, line 2, point 16, line 15 and line 2, points 1 and 17, line 3, 6th and 11 flows back into the coils 19 and 5 and the capacitors 7 and 12.
