Abstract
A circuit for use in an ignition system for an internal combustion engine which includes an electronic switch for control of the charging and discharging of an ignition coil with a capacitive controlled gas discharge tube circuit to provide protection for the electronic switch and permit increased dwell time for the coil.
Claims6
A charging circuit for use in an electronic ignition circuit having an ignition coil controlled by a transistor, said circuit comprising:
- a capacitor connected across the primary coil of the ignition coil and the collector and emitter of a switching transistor therefor;
- and
- gas discharge tubes in a series circuit in parallel with said capacitor between a source of electrical energy and said primary coil, said tubes being between the collector and base of said transistor.
An electronic ignition circuit comprising:
- a source of timed signals:
- semiconductor means responsive to said singals;
- battery means controlled by said semiconductor means;
- ignition coil means operatively connected to be switched by said semiconductor means to receive energy from said battery means;
- a capacitive tuned series circuit of gas discharge tubes about said semiconductor means between said ignition coil means and said battery means.

An ignition system for an engine, said system comprising;
- an electrical power source;
- an ignition coil connected to said source;
- a semiconductor switch means between the source and the coil to provide a means to control the connection therebetween;
- a source of timing signals connected between said power source and said semiconductor means;
- a capacitor means between said source and said coil in parallel with said semiconductor means;
- and
- a series of gas discharge tubes beween said source and said coil about said semiconductor means to enable the operation of said coil to enjoy the gain of the semiconductor means in increasing dwell time of said coil.
