Description

Spark-thermal ignition devices are known that contain two induction ignition coils and a three-electrode discharge that forms two series-connected spark gaps connected to the terminals of the secondary windings of the coils.

The purpose of the invention is to increase the reliability of ignition.

For this, each of the primary windings of the coils in series with a capacitor shunting the coil interrupter is connected in parallel to one of the resistors of the voltage divider at its supply, its current source and equipped with additional matching capacitors, one of which is connected in parallel and the other in series with the contacts interrupters of both coils.

The drawing shows a schematic diagram of the proposed device.

The device contains two induction coils / and 2. Primary windings 3 and 4 coils in series with interrupters 5 and 6, bypass capacitors 7 and 5, are connected in parallel to one of two resistors 9 and 10 of a voltage divider connected to the power supply source . Two additional capacitors 11 and 12 are introduced into the primary winding circuit of the coils. To match the operation of the choppers of both coils, the capacitor 12 is connected in parallel, and the capacitor 11 is in series with the contacts of the choppers 5 and b of both coils, forming a closed loop with the main capacitors 7 and 5 of the coils. A three-electrode arrester 15 is connected to the secondary windings of high voltage 13 and 14 of both coils. Three of its electrodes 16-18 form two series-connected spark gaps, each connected to one of the high-voltage coils of the coils. For this purpose, one of the terminals of each of the windings 13 and 14 is connected respectively to one of the side electrodes 18 and 16 of the discharge. The second terminals of these windings are connected to the corresponding terminals of the primary windings of 3 to 4 coils. The middle electrode of the 17th discharge is connected to the midpoint of the connection of the primary windings of 5 and 4 coils. Thus, the secondary winding 14 of the coil is connected to the electrodes 16 and 17 of the glitter, and the electrodes 17, 18 are connected in series with the primary 3 and secondary 13 windings of the coil. In this case, the voltage on the electrodes 16-17 and 17-18 will be different.
