摘　　要：针对F-T柴油和煤基甲醇在发动机中燃烧时的各自优势,在一台CY25TQ型柴油机上,研究了甲醇占能比及F-T柴油喷油时刻对甲醇均质混合气F-T柴油引燃燃烧方式下发动机排放特性的影响。试验结果表明:随甲醇占能比增加,碳烟和NOx排放明显下降,而THC,HCHO,CO排放上升;F-T柴油喷油时刻提前,CO和NOx排放上升,而碳烟,HCHO,THC排放呈先降低后升高趋势。Based on the Fischer-Tropsch （F-T） diesel and methanol in diesel engine performance on their strengths, an experiment was carried out on CY25TQ diesel engine to investigate the effects of methanol energy proportion and F-T diesel moment on the emission of regulated and non-regulated pollutants characteristics. The results showed that the emission of PM and NOx decreased, but the e- mission of CO,THC and HCHO increased with the increase of methanol energy proportion;With the advance of pilot F-T diesel moment,the emission of NOx and CO increased,but the emission of PM,THC,HCHO decreaseed firstly and then increaseed.
