力センサー内蔵型スパークプラグ。 The spark plug with a built-in pressure sensor consists of a center electrode, a magnetic insulator that surrounds and fixedly supports the center electrode, and a metal shell with an outer electrode at the tip. A small diameter barrel is formed between the large diameter barrel that is in contact with the hexagonal head side and the large diameter barrel thread between the square head and the threaded portion, and the length of the threaded portion is at least magnetically insulating. It is shorter than the length between the stepped part of the inner cavity of the metal shell that supports the base of the truncated cone at the tip of the body and the tip of the threaded part, and the outer diameter of the small diameter barrel is smaller than the outer diameter of the large diameter barrel. A spark plug with a built-in pressure sensor that is larger than the outer diameter of the valley.
