ABSTRACT:
Herein disclosed is a structure of a divided combustion chamber or a pre-combustion chamber of a Diesel engine of the type, in which the divided combustion chamber is composed of an upper ceramic member having a substantially hemispherical head and a lower ceramic member having an injection port. Either one or both of the upper and lower ceramic members is/are formed with longitudinally and/or transversely extending cut or cuts, slit or slits, and/or groove or grooves at least a portion of the outer surface or surfaces of one or two of those ceramic members. Thus, the resistance of the ceramic members to any rupture is improved so that the divided combustion chamber made of ceramic has highly improved durability.
