Effects of altitude and fuel oxygen content on the performance of a high pressure common rail diesel engine.

Highlights: [•] Fuel oxygen content has a more significant effect on soot emission reduction than the altitude effect. [•] The BED fuel with basically the same oxygen content as the BD fuel can reduce soot emissions more. [•] The BSFC of the BED fuel with basically the same oxygen content as the BD fuel is lower.
