Definitions

  • the invention relates to an ignition system for an internal combustion engine with a capacitor and an ignition coil, which comprises a primary winding connected to an ignition current switching unit and a secondary winding connected to the primary winding in an autotransformer series circuit.
  • an ignition system of this type is known from "The great book of automotive electrics", 1973, pages 136 to 142.
  • the primary winding of the ignition coil which is designed as an autotransformer, is connected in series to an interrupter contact to a battery.
  • the breaker contact opens, the current in the primary winding is suddenly interrupted, as a result of which a high voltage is induced in the secondary winding of the ignition coil.
  • a capacitor is connected in parallel to the interrupter contact, which stores the opening induction voltage which arises when the contact opens until the distance between the contacts of the opening interrupter is so large that no arc arises at the interrupter contact.
  • an ignition system is known from US-A-2,981,865, whose ignition transformer comprises a plurality of primary windings in addition to a secondary winding.
  • One of the primary windings together with a capacitor, forms the output resonant circuit of a transistor oscillator operating as a blocking oscillator.
  • Another primary winding forms a feedback winding for the oscillator.
  • the blocking oscillator is controlled by an interrupter contact and oscillates as long as the interrupter contact is closed, the alternating magnetic field of its output circuit inducing high-voltage oscillations in the secondary winding.
  • the capacitor is connected on the high voltage side to the secondary winding to form a pulse oscillator and the series connection of primary winding and secondary winding is connected in parallel. Based on the series connection of the windings, the capacitor forms a parallel resonance circuit whose resonance oscillations increase the high voltage induced on the secondary side when the primary current is interrupted. Charging and discharging take place here via separate lines.
  • the capacitor does not directly bridge a spark gap, but its circuit closes via a primary electrolytic capacitor of the ignition coil or via the vehicle electrical system (battery).
  • the primary winding of the ignition coil is charged with a negative current potential by the charging current of the capacitor lying parallel to the primary and secondary windings, which accelerates the magnetic field breakdown and thus induces a higher voltage on the secondary side. This process is repeated until a flashover occurs on the respective discharge route or routes.
  • the ignition system can include an attenuator, which allows the duration of the ignition current to be extended.
  • Another capacitor can be connected to the primary winding parallel to the arcing distance of the distributor, which leads to a further increase in the ignition voltage and to an almost complete reduction of the magnetic field during the ignition process.
  • a tunable voice coil is provided parallel to the primary winding. With the spark plug tuning plug, the impedance of the spark plug of the ignition system is adjusted.
  • the efficiency of the ignition system is determined by the ignition coil and the pulse oscillator, wherein a tunable coil 19, the inductance of which can be changed by changing the position of its core 21, allows adaptation to the respective requirement.
  • a capacitor 32 is charged from a point 29 via a line 31, a point 16 and a line 15 to the ignition lock from the battery.
  • a control signal from a control device (contacts) via a line 34 to a switching unit 35
  • the negative side of the capacitor 32 is connected via a line 31, a point 30, a line 33, the switching unit 35 and a line 8 with connection points 20 and 36 the coil 19 and the primary winding 5 connected.
  • line 3 leads the current back via points 17 and 16 of lines 15 and 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 primary winding 5 and the coil 19.
  • the charging current is interrupted and the magnetic field begins to collapse in both cores 10, 21.
  • an oppositely directed voltage builds up in the windings 5, 22 and the coil 5.
  • a capacitor 7 is now charged from a point 23 of a line 25 and a point 24 of a line 9.
  • An arc is formed from the current of the candle capacity. This has the consequence that the voltage at the candle breaks down (up to about 50 V).
  • the current now starting from the capacitor 12 via the arc path of the distributor finger 40 and the capacitor 7 via a line 37, the connection point 44 of a candle adapter plug 50, a Winding 45 to connection point 46 ensures that the arc is maintained at the candle with the highest energy.
  • the current flowing in the spark plug tuning plug 50 is then in turn braked by an oppositely directed voltage, which can be influenced by a core 48 in a carrier 47 in such a way that the current flows simultaneously from the deposits on the capacitors 12 and 7 and the secondary winding 22 via ground 29 , the line 31, the capacitor 32, the line 2, the point 16 of the line and 2, the points 1 and 17, the lines 3, 6 and 11 in the coil 19 and the primary winding 5 and the capacitors 7 and 12 flows back.
