[Problem] To enable the use of gas fuels such as CNG in existing diesel engines. [Solution] The present invention is provided with: an injector; an igniter that uses a resonating structure to boost microwaves to perform electrical discharge; and a casing that houses the injector and the igniter. The igniter has: an electrical discharge part; a first section that transmits input microwaves; a second section that performs capactive coupling for matching the impedance of the microwaves and the igniter; and a third section that transmits the capacitively coupled microwaves to the electrical discharge part. The igniter is bent at the boundary of the first section and the second section, the boundary of the second section and third section, or in the first section. |
