Diesel fuel formulation for reduced emissions
摘要：
The invention is directed to a method and formula for producing a fuel having reduced particulate emissions from an internal combustion engine. The fuel taught herein is characterized as having a cetane number ranging from about 45 to about 65, a T95 distillation property of less than about 370° C., and having NR, AR, cetane number and T95 defined by the relation: PEI=156+Z1×(cetane#−49)+Z2×(NR−14)+Z3×(AR−25)+Z4×(T95−315° C.) Where Z1 ranges from abut 0.67 to about 1.06, Z2 ranges from about 0.9 to about 1.28, Z3 ranges from about 2.54 to about 2.80, Z4 ranges from about 0.1 to about 0.4, NR is a defined correlation of the naphthene rings content in the fuel, and AR is a defined correlation of the aromatic rings content in the fuel.
摘要（中）：

本发明涉及一种用于生产具有减少的来自内燃机的颗粒物排放的燃料的方法和配方。 本文教导的燃料的特征在于具有约45至约65的十六烷值，小于约370℃的T 95 C蒸馏性能，并且具有NR，AR，十六烷值和T 由<？in-line-formula description =“In-line Formulas”end =“lead”？> PEI = 156 + Z <1> 定义的< 十六烷-49）+ Z 2 x（NR-14）+ Z 3 x（AR-25）+ Z 4 x（T 95℃-315℃）<？in-line-formula description =“In-line Formulas”end =“tail”？>其中Z <1> 范围为0.67 至约1.06，Z 2范围为约0.9至约1.28，Z 3 3范围为约2.54至约2.80，Z 4范围为约 0.1至约0.4，NR是燃料中环烷烃环含量的确定相关性，AR是燃料中芳环含量的确定相关性。
