<p><P>PROBLEM TO BE SOLVED: To provide a fuel oil composition for premixed compressed self-ignition type engine capable of reducing NOx, PM, etc., contained in a discharge gas of premixed compressed self-ignition type engine and improving fuel cost. <P>SOLUTION: The fuel oil composition for premixed compressed self-ignition type engine has distillation properties represented by formula (1): T<SB>50</SB>+ T<SB>70</SB>×2 + T<SB>90</SB>×3×≤2,200°C (wherein T<SB>50</SB>is 50 vol% distillation temperature; T<SB>70</SB>is 70 vol% distillation temperature; T<SB>90</SB>is 90 vol% distillation temperature) and formula (2):ΔE<SB>270</SB>≥20 vol% (whereinΔE<SB>270</SB>is distillation amount obtained when heated to 270°C) and the fuel oil composition has a cetane number, a density, a whole aromatic content, a content of an aromatic having two or more rings, a sulfur content and a nitrogen content which each fulfill the required conditions. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
