The cold-start ignition and lean blowout LBO performance of F-76 marine diesel fuels, alternative diesel fuel formulations and several blends of F-76 with alternative fuels and a high viscosity diesel calibration fluid, were evaluated in a single-cup swirl-stabilized combustor. The goal was to explore and demonstrate a more cost-effective, flexible and reliable marine diesel fuel qualification protocol for the assessment of F-76 fuel ignition and LBO performance. The study was conducted at the Air Force Research Lab AFRL at Wright Patterson Air Force Base. Test results show that the fuel ignition performance is strongly impacted by the physical properties, particularly viscosity. Improved performance are consistently observed for lower viscosity fuels. Ignition is also impacted by fuel distillation temperatures. The results show that the LBO performance was also strongly correlated with the physical properties, particularly viscosity with best performance observed for lower viscosity fuels.
