A metal outer cylindrical member having a lower restraint portion for restraining the cylinder head is fitted, a heat insulating layer is interposed between the outer cylindrical member and the ceramic member, and the outer cylindrical member is inserted into the cylinder head. In the auxiliary combustion chamber of the engine, which is now installed and fixed, a heat insulating layer is interposed between the upper ceramic member and the cylinder head, corresponding to the position of the upper restraining part of the outer cylinder member. The main feature of the engine is the auxiliary combustion chamber.
