本文介绍了应用高速荧光测温法测量发动机燃烧状态下的气缸盖温度。为了满足测量技术和被测器件的要求，合成了具有特殊成分的Gd3Ga5O12：Cr，Ce热像荧光粉。第一部分给出了校准测量结果，提供了温度寿命特性和时间标准偏差，以量化单次精度。研究了激光诱导加热的准确性。第二部分介绍了光学可访问内燃机内部的测量。确定了气缸盖处的测量位置，以及火花正时和空燃比变化的温度演变。
This paper documents the application of high-speed phosphor thermometry to measure cylinder head temperatures under fired engine conditions. The thermographic phosphor Gd3Ga5O12:Cr,Ce was synthesized with a special composition to meet the requirements of the measurement technique and the device under test. Calibration measurements are given in the first section, providing the temperature lifetime characteristic and temporal standard deviations in order to quantify single-shot precision. Accuracy was investigated for laser-induced heating. Measurements inside an optically accessible combustion engine are presented in the second section. Measurement locations at the cylinder head were determined, as well as temperature evolutions for variations in spark timing and air-fuel ratio.
