UPDATE PROPOSED FOR DIESEL FUEL SPECIFICATIONS
Modifications to diesel fuel specifications have been proposed to bring the properties of the fuel more in line with the needs of the trucking industry, the railroads, and the farm, tractor, and industrial machinery operators. The present diesel fuel specifications and the revised ones proposed by Gilbert K. Brower of International Harvester are presented tabularly. Gravity distribution characteristics are discussed, as well as the maximum cloud point or freezing point. It is also proposed that a 675 F maximum end point requirement be added to D 975 and the present 90% point maximum be reduced from 640 F to 625 F. The minimum cetane number should be raised to 45, while the copper strip corrosion test temperature should be 212 F, and a maximum carbon residue of 0.15% should be specified. Storage stability, thermal (high temperature) stability, and the low-temperature fluidity test are discussed. An analysis of fuel properties, using an up-to-date version of the fuel property map first described by H. Amberg, Chevron Research Company. This map shows how fuel properties are interrelated. An investigation of smoke suppressant additives shows that, although they reduce the level of smoke emitted, undesirable effects occur in some cases.
