摘要： An ignition apparatus is provided which ignites a mixture of air and fuel gas by plasma to generate an initial flame. The apparatus includes: a spark plug that includes an inner conductor, a cylindrical outer conductor that holds the inner conductor thereinside, and a dielectric that is provided between the inner conductor and the outer conductor, and that generates plasma in a plasma formation space between the inner conductor and the outer conductor; an electromagnetic wave power supply that generates an electromagnetic wave to apply electromagnetic wave power to the spark plug; an evaluation section that evaluates a state of formation of the plasma; a determination section that determines a matching object of the electromagnetic wave based on an evaluation result by the evaluation section; and a coupled state control section that controls a matching condition of the electromagnetic wave so that the electromagnetic wave matches the matching object.

摘要： A spark plug adopting an electromagnetic-wave-resonation-structure, efficiently ignites fuel inside a combustion chamber. The spark plug comprises a center electrode configured to transmit an electromagnetic wave having a discharge electrode, the discharge electrode mounted on a distal end of the center electrode, a casing member surrounding a periphery of the center electrode and the discharge electrode and a tip end part thereof functioning as a ground electrode so as to become in pair with the discharge electrode, and a vent configured to allow for an aerial passage is provided at a tip end of the casing member. At that time, the vent can be formed in a slit manner or in a hole type.
