一、前言 活塞温度测量是研究柴油机活塞热负荷,找出强化活塞的途径的一个重要的实测手段,特别对于球型燃烧室,活塞温度又是研究工作过程的重要参数之一。因此,对活塞温度测量的研究工作引起了国内外许多动力工作者的关注。迄今人们已经采用了各种方法进行活塞温度的测量,并取得了成功的经验。如易熔合金法、硬度塞法、示温涂料法、热电偶法、热电 First, the foreword Piston temperature measurement is to study the thermal load of diesel piston, piston to find ways to strengthen an important means of measurement, especially for the spherical combustion chamber, the piston temperature is one of the important parameters of the study process. Therefore, the research on piston temperature measurement has aroused the concern of many domestic and foreign dynamic workers. To date, various methods have been used to measure piston temperature and have gained successful experience. Such as fusible alloy method, hardness plug method, showing temperature coating method, thermocouple method, thermoelectric
