Abstract

A plasma jet plug includes: a tubular insulator having an axial hole; a center electrode disposed inside the axial hole; metal shell disposed on an outer circumference of the insulator; and an orifice electrode electrically connected to the metal shell and disposed on a front side of the insulator. A plasma generating cavity is formed by a surface of the center electrode, an inner surface of the insulator, and an inner surface of the orifice electrode. In the plasma jet plug, a shortest path length D1 of a surface path is greater than or equal to 5 times an aerial gap G, where the surface path extends, inside the cavity, from a surface of the center electrode via an inner surface of the insulator to an inner surface of the orifice electrode, and the aerial gap G is a shortest distance between the center electrode and the orifice electrode.
