Abstract
Diesel fuels which have good ignition qualities, good combustion emission performance and good low temperature characteristics are characterized by a cetane number of at least 45, a total aromatics content of 10 to 15 wt. pct., a polynuclear aromatics content of less than 11 wt. pct., a sulfur content of not more than 50 ppmw, a total nitrogen content (from all sources) of not more than 100 ppmw, and excellent low temperature flow properties as manifested by a pour point not higher than -12.degree. C. and a cloud point not higher than -10.degree. C.
