摘要： PURPOSE:To improve the mechanical strength, heat insulation, heat resistance and durability of a subsidiary combustion chamber of an internal combustion engine, by fixing a disk-like member having a nozzle and made of sintered silicon nitride to the open end of a bell-shaped hollow member. CONSTITUTION:A metal having a coefficient of thermal expansion greater than that of a sintered material of partially stabilized zirconia and smaller than 17X 10 / deg.C always in the temperature range of normal temperatures to 700 deg.C is formed, by way of casting, over the outer surface of a bell-shaped hollow member 2 made of the sintered material of partially stabilized zirconia. Further, a disk-like member 6 having a nozzle 5 and made of sintered silicon nitride is fixed to the open end 4 of the hollow member 2. In fixing the disk-like member 6 to the open end 4 of the member 2, for instance, zircon sand containing water-glass is at first charged into the inside 8 of the hollow member 2 and the nozzle 5 of the member 6 and after the hollow member 2 and the disk-like member 6 are fixed together with hardening of water-glass, they are convered with the metal 3 simultaneously by way of casting. Thus, since the disk-like member 6 made of sintered silicon nitride excellent in heat-insulating properties is fixed to the open end 4, it is enabled to prevent fusion loss at the portion.

摘要： PURPOSE:To avoid the trouble that a struck scar is generated by the interference between the surface of a piston with a subchamber constitution member which shifts in the cylinder direction, by forming a recessed part connected to a grove part, at the part corresponding to the below of the subchamber constitution member on the top surface of the piston. CONSTITUTION:When air and fuel are mixed in an eddy current chamber 2 and combustion is carried out, combustion gas is injected into a main chamber 1 from an injection port 13a. At this time, the combustion gas collides with the top surface 6 of a piston violently, and is guided to a trench 6a. The half combusted gas forms an eddy current in a main chamber 1, because of a recess 6b and a recessed part 6c which are formed in connection with the trench 6a, and is sufficiently mixed with air, and diffusion combustion is carried out. While, even if a piston 5 reaches a top dead center position, the interference between an insertion member 13 which shifts by the generation of a tilt theta in the cylinder direction and the top surface 6 of the piston is prevented, since a nearly arcuate recessed part 6c is formed in correspondence with the outer peripheral shape of the insertion member 13, under the insertion member 13 on the top surface 6 of the piston.
