ことを特徴とするエンジンの副室構造。 In an engine in which a sub-chamber forming member is fitted into a recessed portion of a cylinder head to form a sub-chamber that communicates with a main combustion chamber through a nozzle hole, the sub-chamber forming member comprises:
It is composed of a chamber member made of ceramic material and having a sub-chamber formed therein, and a cylindrical sleeve made of metal that is fitted around the outer periphery of the chamber member and has a gap between it and the cylinder head, and a seal at the upper end of the chamber member. A sealing member having a diameter slightly smaller than the inner diameter of the recess of the cylinder head is interposed between the surface and the cylinder head, and the sleeve has an upper end shorter than the sealing surface of the chamber member so as to have a predetermined gap between the sleeve and the sealing member. A pre-chamber structure of an engine characterized by being configured as follows.
