Abstract
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 deviceand 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 electrodeand a discharge electrodeis increased, and a discharge is caused. In the fuel injection device, a valve body part of a nozzle needleis 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 memberthat is connected to the electromagnetic wave oscillator and formed on the surface of a fuel injection pipe, and an inner wall surfaceof a mounting portfor an injector of a cylinder head. A discharge electrodeis 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 portthat is closest to the discharge electrodeas a ground electrode
