Definitions

  • FIG. 2a is a graph showing the current cycle at a first control element
  • FIG. 2b is a graph showing the voltage cycle at the magneto generator.
  • FIG. 3 shows various kinds of second switching devices that may be used in series with the primary winding 30a of the spark coil. utilizing various kinds of elec tronic circuit components.
  • FIG. 1 shows the circuit of a so-called coil ignition system for a single cylinder internal combustion engine. supplied with current by a magneto generator 10.
  • the latter consists of a rotor ll driven by the internal combustion engine comprising a number of permanent magnets I2 describing a circular path and an armature l3 excited by the motor and carrying an armature winding [4 having one terminal connection l4b grounded to the chassis.
  • the other terminal connection of the armature winding 14 is connected through a diode 15 with an output terminal 16 to which various utilization circuits are connected, which are symbolically indicated by the resistor 17 shown in dashed lines.
  • a magnetic timing pulse generator 24 has its output connected in parallel to the baseemitter path of the control transistor 23 and this mag netic timing pulse generator is connected over a capacitor 25 and a resistor 26 disposed in parallel to the last mentioned capacitor. and further over a diode 27. to the base of the control transistor 23.
  • the base of this control transistor 23 is also connected to ground over a resistor 28. the connection conductor 35 and a resistor 29.
  • the succeeding negative voltage half-wave reaches the face of the transistor 22 over the resistor 36 and switches this transistor by producing a current in its base-emitter path and likewise the transistor 21 by producing a current over its base-emitter path, so that both of these transistors are put into their conducting state.
  • a current 1, begins to flow over the emitter'collector path of the transistor 21 and over the diode 18, which is driven by the voltage produced in the armature winding 14. This current reaches its highest value at the ignition timing moment t,-. At this moment the timing pulse generator 24 produces a control pulse which reaches the base of the control transistor 23 after passing through the capacitor 25 and the diode 27 and causes the control transistor 23 to be switched into its conducting state.
  • the control transistor 23 has its base electrode connected over the resistor 29 to one end of the armature winding 24 in such a way that the voltage pulse produced in the armature winding 24 upon interruption of the current I in the transistor 21 holds the control oil transistor 23 in its fully conducting condition. Only after the control pulse in the timing pulse generator 24 has dropped off and after the voltage pulse in the armature winding l4 has likewise fallen off does the control transistor 23 again go into its non-conducting state and thus again switch the semiconductor switching device I9 into its conducting stage, this switching being accomplished over the resistor 24.
  • VDR voltagedependent variable resistor
  • the Darlington transistor combination shown in FIG. I can be replaced by other electronic switching elements just as the Zener diode 31 can be replaced by other elements as just discussed.
  • a first and second electronic component functioning as a switching device operate together to produce a current-diverting arrangement which first allows the current produced by the magneto generator to flow through the circuit connected in parallel to the primary winding and then at the moment of ignition timing this parallel circuit is opened and the current is suddenly directed over the primary winding of the spark coil and thereby excites a spark.
  • the magneto generator can. without departure from the inventive concept. be equipped with additional power-delivering windings and the ignition system can also be operated with a differently poled winding 14 with corresponding change of the po larity of the various circuit components.
  • An ignition system for an internal combustion engine comprising:
  • a magneto generator having a permanently magnetized rotor driven by said engine and an armature provided with a generator winding arranged for excitation by said rotor;
  • an ignition coil having primary and secondary windings
  • At least one spark plug connected in circuit with said secondary winding
  • semiconductor switching means connected in parallel to said generator winding arranged to be switched from its conducting to its non-conducting state at said ignition timing moment;
  • said semiconductor switching means comprising a first switching device of the semiconductor type (19) having a switching path and a control path and a second switching device (31) connected with said first switching device and said primary winding (a) of said ignition coil (30) in such a way that upon the switching of said first switching device to its non-conducting state said second switching device (31 is switched from its non-conducting to its conducting state.
  • said threshold voltage semiconductor device comprises a plurality of diodes (40) connected in series.
  • said semiconductor control switch (19) comprises a transistor unit (21. 22) having a control path in parallel with which is connected the emittercollector path of a control transistor (23) and in which means are provided for applying a control voltage to the base of said control transistor (23) for switching said emitter-collector path of said control transistor (23) from non-conducting to conducting condition.
  • An ignition system in which the ungrounded end of said generator winding (14) is connected with an additional diode (15) poled with its direction of conduction opposite to that of said first diode (l8) and having its other electrode connected with a connection terminal (id) for supply of current to equipment other than the engine ignition equipment.
