Document Type and Number:
WIPO Patent Application WO/2015/186683
Kind Code:
A1
Abstract:
[Problem] To enable the use of gas fuels such as CNG in existing diesel engines. [Solution] A direct-injection injector unit comprising a plurality of gas fuel injectors and an ignition means for igniting the gas fuel, said injector unit characterized in that the ignition means has a case, a center electrode, and an insulating body that insulates the case and the center electrode; the center electrode has a first electrode into which microwaves are input, a second electrode that is capacitively coupled with the first electrode, and a third electrode that includes a discharge part for discharging; impedance matching of the microwaves is performed using the first electrode and the second electrode; and a series circuit resonates with the microwaves, said series circuit being formed from the ground capacity set by the second electrode and the case, the coil reactance component of the third electrode, and the discharged capacity set by the third electrode and the case.
