为了全面评定内燃机的热负荷,判断受热零件的热状态,研究内燃机传热的基本规律和受热零件实现最优化设计确定边界条件等,必须对受热零件进行全面的温度测量。为此,必须不断完善零件温度的测量技术,特别是活塞温度测量技术。本文就我们在几台内燃机中用各种不同的测试方法所综合的一些基本经验作概要的叙述,介绍内燃机活塞、气缸盖、气缸套温度的测量方法,所采用的测量装置以及测量中的有关技术问题和误差分析。
In order to fully evaluate the heat load of the internal combustion engine, determine the thermal status of the heated parts, study the basic laws of heat transfer of the internal combustion engine and optimize the design of the heated parts to determine the boundary conditions, a comprehensive temperature measurement must be performed on the heated parts. To this end, we must continue to improve the measurement of part temperature, especially piston temperature measurement technology. This article describes some of the basic experiences that we have used in various internal combustion engines with a variety of different test methods. It describes the measuring methods of the internal combustion engine piston, cylinder head and cylinder liner temperatures, the measuring devices used, and the relevant Technical problems and error analysis.
