초록

연료의 성상이 엔진의 착화성에 어떠한 영향을 끼치는가를 규명하고자, 국내에서 생산되고 있는 디젤엔진의 연료인 자동차용 경유에 대하여 물리적인 특성과 화학적인 조성을 시험·분석하고, CFR(Cooperative Fuel Research Committee)엔진을 이용하여 착화성을 나타내는 세탄가를 측정하였다. 시험결과, 세탄가는 비중, 증류성상 등의 물리적인 특성과 Saturates, Aromatics 등의 화학적 조성의 함량비와 상당한 관련성이 있음을 알 수 있었다. 따라서, 이러한 세탄가 관련 요인들을 연료의 제조공정에서 고려하면 디젤엔진의 적합한 착화성을 갖는 연료를 보다 효율적으로 생산할 수 있을 것으로 기대된다.

To examine the efects of fuel properties on auto-ignition in diesel engine, we have studied hte physical properties and the chemical composition of donestic automotive diesel fuel and have measured its cetane number using CFR(Cooperative Fuel Research Committee) engine. It is found that the cetane number is related to the physical properties such as specific gravity and boiling range distribution, and to the saturates and aromatic contents of diesel fuel. Therefore, it is suggested that in the refining processes the factors affecting the saturates and aromatic contents of diesel fuel. Therefore, it is suggested that in the refining processes the factors affecting the cetane number stated above should be taken into account to improve the autoignition property of automotive diesel fuel.

Keywords:Ignition Delay;Cetane Number;Specific Gravity;Distillation;Saturates;Aromatics
