Title:
窒素酸化物排出量を低減する方法
Document Type and Number:
Japanese Patent JP2013514436
Kind Code:
A
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 comprising Atotal=Ax+10(Ay) wherein Ax is the UV absorbance at 272 nanometers; and wherein 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.
