缸内压缩温度对柴油机的着火与燃烧有着重要影响，本文介绍用双曝光全息干涉法测取柴油机压缩温度场的基本原理及实验过程，在实际发动机中测取了压缩过程中缸内的温度分布及变化历程，为柴油机压缩过程缸内温度分布的定量测量提供了一种新的方法。
The compression temperature in cylinder plays an important role in the ignition and combustion of diesel engine. This paper introduces the basic principle and experimental process of measuring the compression temperature field of diesel engine by double-exposure holographic interferometry. In the actual engine, the temperature distribution in the cylinder is measured And the changing course, provides a new method for the quantitative measurement of temperature distribution in the cylinder of diesel engine.
