B108 CMOSカメラを用いた二色法によるディーゼルエンジンの燃焼温度計測に関する研究

測定精度の定量評価についての検討

Flame temperature is an effective indicator to estimate the amount of NOx formation. The Two-Color Method (TCM) is widely used to measure flame temperature of diesel combustion because the TCM can calculate temperature from color information of flame images. Taking flame images using the CMOS camera and analyzing those on TCM, however, have some problems such as the limitation calibrated range or measurement accuracy, by having digitalized all processes of the analysis. The purpose of this study is to evaluate the measurement accuracy of TCM analysis using CMOS camera.
