| 中文摘要 |
| 在两辆试验车上分别燃用纯汽油、M15、M30燃料以及纯汽油、E10、E20燃料,进行了常温25℃Ⅰ型、低温-7℃Ⅵ型和Ⅳ型蒸发排放试验. 通过FTIR、HPLC、GC-MS等多种方法联合测量了醇类汽油车的醇醛酮、芳香烃和烯烃类排放. 结果表明,不论是在常温还是在低温下,随着燃料中醇类比例的增加,未燃甲醇、甲醛、乙醛排放成比例地增加,苯、甲苯、乙烯、丙烯、1,3-丁二烯和异丁烯排放略有降低. 在低温环境温度下,各种非常规污染物的排放明显高于在常温环境温度下. E10、汽油、M15这3种燃料在整个蒸发排放试验过程中的HC排放量相差不大. 3种燃料在昼间呼吸试验中的各种非常规污染物蒸发排放差异值较小. |
| 英文摘要 |
| Using two vehicles fuelled with pure gasoline, M15, M30 and pure gasoline, E10, E20 separately, 25℃ normal temperature type Ⅰ emission test, -7℃ low temperature type Ⅵ emission test and type Ⅳ evaporation emission test were carried out. FTIR, HPLC and GC-MS methods were utilized to measure alcohols, aldehydes, aromatic hydrocarbons and olefins emissions. The test results indicate that at the low as well as normal ambient temperature, as the alcohols proportion increasing in the fuel, unburned methanol, formaldehyde, acetaldehyde increase proportionally, benzene, toluene, ethylene, propylene, 1,3-butadiene and isobutene decrease slightly. The unregulated emissions at the low ambient temperature are significantly higher than those at the normal ambient temperature. The difference of HC emissions in the entire process of evaporative emission tests of E10, gasoline and M15 fuels is slight. There is a small difference of unregulated emissions in the diurnal test of three fuels. |
