Document Type and Number:
Japanese Patent JPH06100087
Kind Code:
B2
Abstract:
PURPOSE:To prevent ceramic materials from damages, combustion gas from leakage and a metallic tube from brakage and cracks by providing a specified weight percentage of the material of metallic tube shrunk on the outer periphery of a ceramis auxiliary chamber constituting member. CONSTITUTION:An auxiliary combustion chamber 1 is provided in a cylinder head 3 forming the upper surface of a main combustion chamber and constituted from an upper member and a lower member 6 formed of a ceramic material. A metallic tube 8 is shrunk on the outer periphery of a ceramic auxiliary chamber constituting member 17. For the material of the tube 8 is used martensite system heat resisting steel having low coefficient of thermal expansion, excellent heat resisting property and workability as well as excellent shrinking property. Thus, the ceramic materal can be prevented from damages, combustion gas prevented from leakage and the tube can be prevented from cracks and breakage.
