摘　　要：在一台单缸柴油机上进行了低温燃烧试验,研究了生物柴油对一氧化碳(CO)和碳氢(HC)排放的影响,并分析了这两种排放产物与基本燃烧参数之间的相关性.结果表明,CO排放在大的当量比下主要与当量比相关,在中低当量比下与最高平均燃烧温度相关.HC排放主要与滞燃期和最高平均燃烧温度相关.生物柴油和柴油CO和HC排放的差别主要取决于以上燃烧参数.生物柴油的CO排放与柴油相当,HC排放比柴油低.Tests were carried on a single cylinder diesel engine fueled with diesel and biodiesel in low temperature combustion mode. Emissions of carbon monoxide （CO）and hydrocarbons （HC）were studied. CO emission has correlation to equivalence ratio at large equivalence ratios and has correlation to peak in- cylinder gas temperature at moderate and low equivalence ratios. HC emission has correlation to ignition delay and peak in-cylinder gas temperature. The differences of CO and HC emissions between diesel and biodiesel depend on their differences in equivalence ratio, ignition delay and peak in-cylinder gas tem-perature. CO emission of biodiesel is comparable to that of diesel, while HC emission of biodiesel is lower than that of diesel.
