ABSTRACT:
A low emission diesel fuel suitable for use in underground diesel-engined mining equipment comprises a straight run distillate fuel having an end point not greater than 300.degree. C. (about 660.degree. F.), a cetane number in the range of 55 to 60 a specific gravity not greater than 0.83 a sulfur content not greater than 0.1 wt percent and an aromatics content of 18 to 30 wt. percent. The T.sub.90 of the fuels is typically in the range of 255.degree. to 270.degree. C. (about 490.degree. F. to 525.degree. F.), with an initial boiling points typically in the range of 170.degree. to 190.degree. C. (about 340.degree. to 374.degree. F). Ten percent points (T.sub.10) are typically in the range from about 200.degree. to 220.degree. C. (about 390.degree. to 430.degree. F.). The API gravity of the fuel is at least 38 and is typically in the range of 38 to 42 and the specific gravity is typically in the range of 0.82 to 0.83.
