内燃机壁面温度特性的实验研究

A Experimental Research into the Temperature Characteristics of the Cylinder Wall in the Internal Combustion Engine

本文介绍了局部和缸壁平均温度对内燃机瞬时传热特性影响的实验结果。为此目的,作者研制了一种特殊的薄膜热电偶——膜温可控式表面热电偶,并在一台点火式发动机上进行了实测,其测试数据及分析的结果是有意义的。

This paper introduces the experimental result of influence of the mean temperature of partial cylinder to transient heat transfer characteristic of internal combustion engine. For this purpose, the auther designs a special film thermorcouple-surface thermocouple with film temperature control and carry out the test at a spark-ignition engine. The test data and analysis of the result obtained arc interesting.
