| 摘 要： | 通过对轻型车燃用生物柴油和0#柴油尾气排放的测量和分析，研究瞬态工况有害排放物模态特性。试验结果表明，与0#柴油相比，轻型车燃用生物柴油可显著改善冷启动过程的HC和CO排放，其HC、CO和PM比排放分别降低76．9％、45．7％和52．8％，但NOx比排放增加5．8％。燃料在燃烧转变为CO2和H2O释放出化学能的同时也将空气中的N2氧化成NOx，因而可用NOx／CO2来描述NOx排放随运行工况的变化规律。

| Abstract: | By measuring and analyzing the exhaust emissions of a hght-duty vehicle fueled with biodiesel and No. 0 diesel fuel, the characteristics of emissions under transient operation condition are investigated. The test results show that compared to No. 0 diesel fuel, the HC and CO emissions of vehicle fueled with biediesel at cold start are markedly improved. The specific emissions of HC, CO and PM decrease by 76. 9%, 45.7% and 52. 8% respectively, but the specific NOx emission rise by 5.8%. |
