Ignition system of an internal combustion engine

摘要

An ignition system of an internal combustion engine comprising a metallic plate inserted between the cylinder block and the cylinder head. The metallic plate has an opening, upon the inner peripheral wall of which is mounted a plurality of T-shaped electrodes. Each of the T-shaped electrodes comprises an electrode piece and a conductive bar member connected to the electrode piece. The conductive bar member is surrounded by a tubular insulating member. The tubular insulating member is inserted into bores formed in the metallic plate for forming a condensor between the conductive bar member and the metallic plate. The electrode pieces are arranged in series for forming spark gaps between adjacent electrode pieces, and a high voltage is applied across the electrode pieces.
