以一辆满足国Ⅴ排放标准的新生产轿车为试验样车，在N EDC测试循环下，车辆分别燃用国Ⅴ汽油和F‐T汽油，应用全流稀释排放测试系统进行了气态污染物排放、颗粒物质量排放和颗粒物数目排放的对比研究。研究结果表明：相较于燃用国Ⅴ汽油，燃用F‐T汽油后 T HC排放和CO2排放分别降低了14．3％和2．8％，CO和NOx 的排放分别增加26．8％和104．8％，颗粒物质量排放量（PM ）和粒数排放量（PN ）分别下降了26．5％和39．1％。研究分析表明，满足国Ⅴ排放标准的轻型汽车在不进行人为调整的条件下，具有较好的F‐T 汽油使用适应性，且燃用F‐T汽油比燃用国Ⅴ汽油具有更好的燃油经济性以及更低的温室气体排放。%The gaseous pollutants ,particulate mass and particulate number of China‐Ⅴ passenger car fueled with China‐Ⅴgasoline and fischer‐tropsch (F‐T ) gasoline respectively were measured with the full‐flow dilution test system according to NEDC test cycle .The results show that THC ,CO2 ,PM and PN reduces by 14 .3% ,2 .8% ,26 .5% and 39 .1% respectively and CO and NOx increases by 26 .8% and 104 .8% after using F‐T gasoline .It is found that China‐Ⅴ light‐duty passenger car has good adaptability to F‐T gasoline without artificial intervention .Furthermore ,F‐T gasoline has better fuel economy and lower greenhouse gas emission than Chian‐Ⅴ gasoline .
