IGNITION PLUG AND IGNITION SYSTEM PROVIDED WITH SAME

Title:

IGNITION PLUG AND IGNITION SYSTEM PROVIDED WITH SAME

Document Type and Number:

WIPO Patent Application WO/2017/110209

Kind Code:

A1

Abstract:

According to the present invention, in an ignition plug (1), due to a ground electrode (14) being set to have a thin rod or net shape, a sufficiently strong radical is generated locally via a barrier discharge and the quenching effect by the electrode is small and flame growth is not readily prevented. Further, by making a thickness dimension of a second dielectric body (12b) facing a discharge region (15) uniform, the barrier discharge expands on a surface of the second dielectric body (12b), radical generation is maintained and combustibility after ignition is promoted. Further, an end part (11c) of a high voltage electrode (11) and the ground electrode (14) are arranged facing one another in a combustion chamber (22), so a fuel gas introduced to the combustion chamber (22) readily flows to the discharge region (15) and is readily ignited by the radical generated via discharge.
