Ignition method for generating discharge plasma by high frequency field and direct current impulse, particularly for internal combustion engine, involves supplying high frequency voltage on spark electrode and counter electrode

摘要

The ignition method involves supplying a high frequency voltage on a spark electrode (1) and a counter electrode (2) during the direct current impulse generation. The ignition impulse of a direct current impulse has a negative or positive polarity, where the high frequency voltage develops a high frequency field around the spark electrode. The environment of the spark electrode ionizes the air, gas or gas-air mixture for developing the spark-discharge plasma. An independent claim is included for a device for generating discharge plasma by a high frequency field.
