柴油机中燃烧室的温度大约与排气阀和燃气透平的叶片相当。因此,它在热强度和热稳定性方面也提出了相仿的要求。然而与阀杆不同点在于它在运功状态方面没有要求。但是,根本的区别在于:燃烧室是在冷态下安装好的,因此当加热时就不能自由地膨胀。现就这一观点,阐述一下所积累的经验。1.燃烧室特有的要求柴油机气缸头中涡流室式的或者预燃室式的燃烧室通常在下部折断,这一部分常称之谓“燃烧室喷嘴”或者“喷燃器”,它的温度最高,因此这一部分由耐热的贵重钢材制造并装在气缸头内,联接方式不仅有压配合而且也采
The temperature of the combustion chamber in a diesel engine is about the same as that of the exhaust valve and the gas turbine. Therefore, it also made similar demands in terms of thermal strength and thermal stability. However, the difference with the stem is that it has no requirements on the operational status. However, the fundamental difference is that the combustion chamber is installed in a cold state and therefore can not freely expand when heated. Now on this view, elaborate on the accumulated experience. 1. Specific requirements of the combustion chamber The swirl chamber or pre-combustion chamber in the cylinder head of a diesel engine usually breaks down at the lower part, which is often referred to as “combustion chamber nozzle” or “burner” and has the highest temperature , So this part is made of heat-resistant precious steel and installed in the cylinder head, the connection is not only a pressure fit but also mining
