Abstract
PURPOSE: To improve ignitability and prevent escape of exhaust gas, minimizing actually opening diameter of the plug hole, by projecting the end suface of side fittings in the semi plug along surface from the end surface of the insulator by prescribed height.
CONSTITUTION: In the rotary engine which semi plug 10 along surface is screwed in the rotary casing, which formes spark gap with air gap ga followed the plug along surface gs formed at the insulator, having a side fittings 15 as a grounding electrode which covers the outer surface of this insulator 13 and an insulator with a center electrode 12, the end surface of above side fittings 15 is projected outwards axially from the end surface of the insulator 13 by prescrived height, slit 14 having prescribed width 1 is formed raidially at the end surface of side fittings 15, fresh air from operating chamber is led into the plug smoothly by inclining the bottom surgace 14a of the slit 14 so that scavenging may be carried out smoothly
