Abstract
A method of reducing nitrogen oxide emissions, the method comprising
- (i) injecting a petroleum-derived diesel fuel composition having: (a) a sulfur content of less than 10 ppm;(b) a flash point of greater than 50° C.;(c) a UV absorbance, Atotal, of less than 1.5 as determined by the formula comprisingAtotal=Ax+10(Ay) wherein Ax is the UV absorbance at 272 nanometers; andwherein Ay is the UV absorbance at 310 nanometers; (d) a naphthene content of greater than 5 percent;(e) a cloud point of less than −12° C.;(f) a nitrogen content of less than 10 ppm; and(g) a 5% distillation point of greater than 300 F and a 95% distillation point of greater than 600 F, in an advanced combustion engine; (ii) combusting the petroleum-derived diesel fuel in (i) in a combustion chamber of a non-spark ignited engine, wherein nitrogen oxide emissions are lower than those nitrogen oxide emissions when a conventional diesel fuel is employed in a non-spark ignited engine.
