A funnel-shaped cone (9) having an opening (13) at the top portion is provided in combustion chamber (5) so as to be spaced from an igniter. An inflammable gaseous mixt. is introduced into the combustion chamber, and it flows to the opening through the cone. The gaseous mixt. is ignited by the igniter at the opening, and a flame produced is radiated outside into the chamber along the outer surface (22) of the core. If the cone is provided at the tip of the igniter, i.e. a spark plug (6), the above-mentioned operation can also be applied to an already manufactured spark ignition engine. In a fludised internal combustion engine, the cone is provided in a combustion chamber, and the initial combustion is carried out on the outer surface of the cone, the secondary combustion being carried out in the interior of the cone. |
