Methodology to evaluate Fuel Quality in terms of Ignition and Combustion

연소 관점에서 본 연료 품질 판단 방법

The ignition quality in diesel engines is one of the most important factors influencing their performance. While the ignition quality of distillation fuels is judged with Cetane Number, Cetane Index, and Diesel Index, that of residual fuels blended with distillation fuels is done by using CCAI. Since the 1980s, because of the development in the blending technology and the complexity, it has been difficult to make a judgement on the ignition quality of the fuels with CCAI. Hence, in order to solve the problems, it is ECN that researchers are studying in depth. In this paper, After reviewing the values such as Cetane Number, Cetane Index, Diesel Index, CCAI, and CII, we will introduce ECn and predict the possibility of using it.
