Abstract

Effect of 2, 5-dimethylfuran (DMF) addition in diesel fuel on combustion, performance and emissions was investigated in a modified single cylinder engine. Results show that DMF blended increases fuel ignition delay and premixed combustion proportion, in-cylinder peak pressure and maximum pressure rise rate and reduces significantly smoke emission. Especially for DMF addition of 40%, nearly zero smoke emission can be realized over whole tested EGR rate range. NO_x emissions increase with DMF fraction increasing. Raising EGR rate can decrease greatly NO_x emissions without increasing smoke. When EGR rate exceeds 50%, both NO_x and smoke emissions are nearly zero for blend DMF40. Compared to pure diesel fuel, blend fuels produce quite more THC and CO emissions. By optimizing combustion phasing max. pressure rise rate and NO_x emissions can effectively be reduced with remaining acceptable thermal efficiency, but THC and CO emissions will increase.
