There are numerous federal, military, and commercial diesel fuel specifications used by industry as guidelines for selection. Detroit Diesel Engine Div. divides the popular fuel specifications into four categories for the purpose of using terms and values of reference. These are CITE, jet-turbine, light, and heavy grade fuels.
DDED manufactures engines to operate on fuels classified as grades 1-D and 2-D of ASTM D 975, and publishes a Fuel Oil Selection Chart in which fuels defined for specific service applications are indicated. Final boiling point, sulfur content, and cetane number limits are specified to assure fuel uniformity and satisfactory performance.
The performance of barium containing smoke suppressant diesel fuel additives in dynamometer engines under sustained and cyclic operating conditions was investigated. The ash deposits obtained using additive treated fuel were relatively heavy compared to the levels obtained using untreated fuel.
