气缸活塞组零件的温度状态是决定发动机有效指标和影响其可靠性及寿命的重要因素之一。有许多研究工作测量过活塞和气缸的温度变化。但是实际上却没有关于拖拉机用柴油机气环的温度状态的资料。参考文献1和2中叙述的活塞环温度测量方法,由于活塞环和活塞之间引线不够耐久,没有得到推广应用。因此,产生了制定比较完善的测量活塞环温度的方法和研制这种装置的必要性,这种方法和装置要保证引线能可靠耐久使用、热电偶引线有可靠的绝缘、热电偶热接点和活塞环有
Cylinder piston assembly temperature status is to determine the effective indicators of the engine and affect the reliability and life of one of the important factors. There are many studies measuring the temperature changes of pistons and cylinders. But in fact there is no information about the temperature status of the gas ring of a tractor diesel engine. The piston ring temperature measurement methods described in Refs. 1 and 2 have not been widely applied because the leads between the piston ring and the piston are not durable enough. Therefore, a well-developed method of measuring the temperature of the piston ring and the necessity of developing such a device have been developed which ensure reliable and durable use of the lead, reliable insulation of the thermocouple lead, thermal contact of the thermocouple and the piston Ring there
