摘要: Abstract This study is aimed to investigate the performance, combustion, and emissions of a common-rail diesel engine fueled with IBE blends. Two blends fuel, denoted as IBE15 (15% 85% in volume) IBE30 (30% 70% volume), were tested under different injection strategies. The experimental results show that compared single injection, in-cylinder pressure heat release rate curves (HRR) for all fuels double cases are less severe. That say, pilot can reduce knocking combustion ringing intensity when blending high ratio into diesel. Furthermore, helpful improving both performance economy fuels, especially IBE30. For almost conditions, present potential soot but increase NOx emissions. A favorable causes increase. Results also flame lift-off length much longer than pure feature may result better air-fuel mixing, which then contributes
