Document Type and Number:
WIPO Patent Application WO/2016/125857
Kind Code:
A1
Abstract:
[Problem] A spark plug in which an electromagnetic wave resonator structure is used, wherein fuel in a combustion chamber is effectively ignited. The present invention is provided with: a center electrode for transmitting electromagnetic waves; a discharge electrode attached to the distal end part of the center electrode; and a case member enclosing the periphery of the center electrode and the discharge electrode, the distal end portion of the case member functioning as a ground electrode forming a pair with the discharge electrode. A vent part allowing the passage of a gas is provided to the distal end part of the case member. The vent part may be formed so as to have a slit shape or a hole shape.
