摘要： An ignition plug providing excellent ignition performance that can be maintained over a long period of time by restraining channeling. The ignition plug includes a ceramic insulator having an axial bore, a center electrode inserted into the axial bore, a metallic shell, and a ground electrode fixed to the metallic shell, and has a cavity defined by an inner circumferential surface of the axial bore and the forward end surface of the center electrode. The axial bore includes a first straight portion and a diameter-reducing portion. As viewed on a section which contains an axis (CL1) of the ignition plug, a relational expression α≧10 is satisfied, where α (°) is an acute angle formed by a straight line orthogonal to the axis (CL1) and the outline of the diameter-reducing portion.

摘要： A plasma jet ignition plug including an insulator having an axial hole extending therethrough in the direction of an axis CL1, a center electrode inserted into the axial hole, and a ground electrode disposed frontward of the front end of the insulator. The insulator has a cavity defined by the wall surface of the axial hole and the front end surface of the center electrode and opens frontward. The ground electrode has a through hole for establishing communication between the cavity and an ambient atmosphere. A front end portion of the center electrode is formed into a taper portion whose diameter reduces frontward in the direction of the axis CL1. The outside diameter of a front end of the taper portion is smaller than the diameter of the through hole. The cavity has a substantially constant diameter with respect to the direction of the axis CL1.
