| 中文摘要: |
| 对怠速工况下使用乙醇汽油汽车尾气中污染物进行了检测。结果表明, 使用乙醇汽油后, 汽车尾气中CO和HC浓度明显降低, 平均下降率为56.9% 和38.2%;NO x 平均下降率为 15.0%;CO 2 浓度平均增长率为5.04%; 苯系物浓度明显降低, 平均下降率在45.5% ～ 53.1%; 醛类的浓度增加明显,平均增长率在47.8% ～ 293%; 丙酮、丁酮的浓度增加, 分别为 16.6% 和 25.3% 。 |

The resultshowed thatthe contentsofcarbon monoxide and hydrocarbon decreased remarkably, and the average rates were56.9 % and 38.2% separately, the NO x dropped 15.0 % , average growth rate of the carbon dioxide was5.04% ,thecontentsofaromaticcompoundsfellfrom 45.5% to 53.1 %. Thecontentofal dehydesincreased obviously and average growth ratesin 47.8 % ～ 293 % ,the average growth ratesofacetone and butanoneincreased16.6 % and 25.3 % respectively. |
