다국어 초록 (Multilingual Abstract)

The temperature and soot of the visualized diesel engine's turbulent flow of flame was qualitatively measured. In combustion chamber, in order to judge the affect that the swirl has on the in-cylinder's current , was used two different heads with different values. Using the high speed camera, and the results were analyzed using the heat release rate produced by the pressure sensor. In order to measure the temperature and soot of the turbulent flames like that of the diesel flames two color methods were used temperature and the soot of the flames according to the conditions through analyzing the two wavelengths of the flames. It was possible to measure the highest temperature of the non-swirl head visualized engine which is approximately 2400K, and that swirl head engine managed up to 2100K. With respect to the visualized diesel engine soot, we got the grasp of the KL factor which bears the qualitative information of soot. This study is dedicated to suggesting the possibility of measuring not only the temperature but also soot of the diffusion flame of the diesel engine turbulent flames through such method.
