The individual effects of cetane number, oxygen content or fuel properties on performance efficiency, exhaust smoke and emissions of a turbocharged CRDI diesel engine - Part 2

The brake thermal efficiency equally increased by 0.5%, NOx emissions by 15.8% or 2.7%, smoke and CO decreased 1.7 times or by 34.9% and 7.2 times or increased by 18.8% when running with the most flammable (CN = 67.3) fuel blends E or B at λ = 1.20 and the high speed of 2500 rpm. The engine efficiency increased by 2.9% or 0.5%, NOx emissions by 10.6% (1.81 wt%) or 5.0%, smoke and CO emissions decreased 3.0 times or by 46.7% and by 63.3% (3.61 wt%) or 49.5% when using the most oxygenated (4.52 wt%) fuel blends series E or B under given test conditions.
