Title:
IGNITION SYSTEM FOR INTERNAL COMBUSTION ENGINE, AND INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2015/025913
Kind Code:
A1
Abstract:
[Problem] To provide an ignition system for a compact internal combustion engine, which does not require a complex system or a spark plug which discharges a high voltage, and which, by using only electromagnetic waves, can efficiently generate, expand and maintain plasma. Moreover, to provide an internal combustion engine. This ignition system is characterized by comprising: an electromagnetic wave oscillator (3) which oscillates electromagnetic waves; a control device (4) that controls the electromagnetic wave oscillator (3); and a plasma generator (10) which integrates a booster circuit (5) containing a resonant circuit capacitive coupled with the electromagnetic wave oscillator (3), and a discharge electrode (6) which discharges a high voltage generated by the booster circuit (5), wherein the plasma generator (10) comprises a plurality of discharge electrodes (6) arranged so as to be exposed within the combustion chamber of the internal combustion engine.
