Abstract
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.
