Technology for Use of Variable Quality Fuels
Abstract
This program was intended to determine the specification properties of diesel fuel that can be varied and relaxed with little or no performance or handling penalties by using modified bench and engine tests. Specially blended test fuels were used that had selected properties outside of specified limits in Federal Specification VV-F-800D, Fuel Oil, Diesel, Grade DF-2. The properties investigated were cetane number, viscosity, distillation temperature limits at 90-percent recovered and end point, accelerated stability values, and carbon residue on 10-percent bottoms. Cold-starting tests to investigate the effect of fuel cetane numbers and viscosities were conducted with engines common to the Army inventory as follows: Detroit 6V-53T, Continental LDT-465-1C, Cummins NHC- 250, and General Motors 6.2L. The effect of higher 90-percent distillation and end-point temperatures than specified was investigated using a Petter model PH1W single-cylinder diesel engine. Keywords: Diesel fuel, Fuel, Fuel oils, Diesel engine, Cetane number, Viscosity, Stability.
