INJECTOR BUILT-IN IGNITION DEVICE, INTERNAL COMBUSTION ENGINE, GAS BURNER, AND IGNITION DEVICE

The object is to provide an injector with a built-in ignition device that can achieve downsize of device as a whole without changing significantly the structure of a fuel injection device. The injector with the built-in ignition device comprises an ignition device and a fuel injection device . In the ignition device , an electromagnetic wave oscillated from an electromagnetic wave oscillator MW is boosted by a booster that is constituted by a resonance structure, a potential difference between a ground electrode and a discharge electrode is increased, and a discharge is caused. In the fuel injection device , a valve body part of a nozzle needle is moved toward or away from a valve seat (orifis) , and thereby, the fuel injection control is performed. Then, the resonance structure is formed by a dielectric member that is connected to the electromagnetic wave oscillator and formed on the surface of a fuel injection pipe , and an inner wall surface of a mounting port for an injector of a cylinder head . A discharge electrode is a projection that is formed on the surface of the fuel injection pipe , and a discharge is caused by making a position of the wall surface of the mounting port that is closest to the discharge electrode as a ground electrode
