Abstract

PURPOSE: To increase purifying efficiency and combustion efficiency of exhaust gas by forming a sub-combustion-chamber in front of a spark discharge electrode part and arranging a dense mixed gas passage which communicates with the sub- combustion-chamber and arranging, at the exit of the passage, a check valve which is opened by the negative pressure in the cylinder.
CONSTITUTION: The tubular center electrode main part 1 having condensed mixed gas passage 2 arranged inside is equipped with a valve seat 4 at the lower end opening and fixed at the center part of an insulator 3 by cement or glass seal. In the lower part of the passage 2, a movable center rod 5 having a plurality of guide pieces 6 arranged in the periphery is arranged slidably up and down, and at the lower part of the center rod 5, a valve 7 and a center electrode 5' are arranged. The movable center rod 5 is energized in the direction of always closing by the tension spring 8 arranged in the upper part. In the periphery of the insulator 3, is arranged a metal fitting which has a cylindrical part at the lower part and has sub-combustion-chamber 11 inside, and the ground electrode 12 arranged in the upper part of the sub-combustion-chamber 11 is disposed oppositely to the center electrode 5'.
