Abstract

PURPOSE:To improve the heat insulating property and durability of a whirl chamber bole formed at a whirl chamber formed as a sub combustion chamber by forming an injection port unit to a main combustion chamber of heat resistant heat resistance impact ceramic and the inner wall of the whirl chamber of heat insulating ceramic. CONSTITUTION:In a diesel engine, a sub combustion chamber communicating via an injection port 7 with a main combustion chamber 6 is formed as a whirl chamber 5, which is formed by mounting a whirl chamber port unit 3 on a cylinder head 4. The outer periphery of the port unit 3 and a part of the inner wall of the whirl chamber 5 are formed of the first member 1 made of ceramic having excellent heat insulating property, the port 7 is formed of the second member made of ceramic having excellent heat resistance and thermal impact resistance, and the port unit 3 is formed of both the members 1, 2. In this case, crystallized glass or the like is, for example, used as the first member 1, and nitrided silicon or the like is used as the second member 2. In this manner, the heat resistance and the durability of the port unit 3 can be improved.
