ABSTRACT:
The heat-insulating engine with swirl chambers of this invention comprises thin members made of a monolithic ceramic material for forming the surface portions of swirl chambers communicating with main combustion chambers through communication ports, high rigidity outer wall members made of a monolithic ceramic material for forming the outer peripheral portions, and swirl chamber inner wall members made of a ceramic whisker material and disposed between the thin members and the high rigidity wall members. Therefore, this heat-insulating engine with swirl chambers has high thermal stress assured by the thin members, high mechanical strength secured by the high rigidity wall members and high heat-insulating property attained by the swirl chamber inner wall members. Moreover, since the outer wall members have high rigidity and since the swirl chamber inner wall members can offset the stress of the thin members such as deformation, mechanical stress hardly acts on the thin members, though the terminal stress alone is applied thereto. Accordingly, strength of the thin members can be secured.
