Definitions

  • the invention is based on an ignition system according to the preamble of the main claim.
  • Such an ignition system is already known (according to FIG. 3 of DE-AS 23 39 784), but it can happen that if one of the diodes is damaged and no longer has a blocking effect, the spark plug lying in series in the wrong place When an ignition spark is generated that does not exclude damage to the internal combustion engine.
  • US-A-4,411,247 also shows and describes a distributorless ignition system, diodes being arranged between the ignition coil and spark plugs, so that depending on the polarity of the ignition pulse, only the spark plugs ignite, the diode of which has the corresponding polarity.
  • the ignition system shown schematically in the drawing is intended for an internal combustion engine (not shown) of a motor vehicle (also not shown).
  • This ignition system is fed from a direct current source 1, which can be the battery of the motor vehicle.
  • a line 2 connected to ground starts from the negative pole and a supply line 4 containing an operating switch (ignition switch) 3 starts from the positive pole.
  • the supply line 4 leads to a middle tap 5, from which a primary winding section 6 and a primary winding section 7 originate.
  • the primary winding sections 6, 7 sit on an iron core 8 and form an ignition coil 10 with a secondary winding 9 which is also located on the iron core 8.
  • the free connection of the primary winding section 6 is connected to the anode of a blocking diode 11, the cathode of which is applied to the collector with its emitter the ground line 2 lying transistor 12 is connected.
  • the free connection of the primary winding section 7 is connected to the anode of a blocking diode 13, the cathode of which is connected to the collector of a transistor 14 with its emitter connected to the ground line 2.
  • the base of transistor 12 and the base of transistor 14 alternately receive switch-on pulses 15, 16.
  • One terminal 17 of the secondary winding 9 is connected to the anode of a diode 18 and to the cathode of a diode 19.
  • the cathode of the diode 18 is connected to the ground line 2 via a spark plug 20 and the anode of the diode 19 via a spark plug 21.
  • the spark plug 20 is connected in parallel with the anode on the ground line 2, the diode 22, while the spark plug 21 is a diode 23 in the shunt, which is connected at its cathode to the ground line 2.
  • the other terminal 24 of the secondary winding 9 is connected to both the anode of a diode 25 and the cathode of a diode 26.
  • the diode 25 has a connection to the ground line 2 at its cathode via a spark plug 27 and the diode 26 at its anode via a spark plug 28.
  • the spark plug 27 is connected in parallel with the anode on the ground line 2 diode 29, while the spark plug 28 has a diode 30 in its shunt, the cathode of which is connected to the ground line 2.
  • the switch-on pulse 15 is now effective, whereupon the primary winding section 6 is switched on and off by the transistor 12. Switching off the primary winding section 6 should result in a high voltage surge in the secondary winding 9, in which the connection 17 is positive and the connection 24 is negative. This high voltage surge will result in a spark at the spark plugs 20, 28, while an effect on the spark plugs 21, 28 is blocked by the diodes 19, 26.
  • the switch-on pulse 16 then comes into effect, the primary winding section 7 is switched on and off by the transistor 14, a high voltage surge now occurring in the secondary winding 9, in which the connection 24 becomes positive and the connection 17 becomes negative.
  • ignition sparks will now occur on the spark plugs 21, 27, while ignition sparks on the spark plugs 20, 28 are prevented by the diodes 18, 26.
