IGNITION SYSTEM FOR INTERNAL COMBUSTION ENGINE, AND INTERNAL COMBUSTION ENGINE

摘要

The ignition system has an electromagnetic wave oscillator which oscillates electromagnetic waves, a control device that controls the electromagnetic wave oscillator, a plasma generator which integrates a booster circuit containing a resonant circuit capacitive coupled with the electromagnetic wave oscillator, and a discharge electrode which discharges a high voltage generated by the booster circuit. The plasma generator includes a plurality of discharge electrodes arranged so as to be exposed within the combustion chamber of the internal combustion engine.
