摘要： 非常规污染物排放成为制约甲醇替代燃料规模发展的制约因素。该文作者使用一辆分别燃
用纯汽油、汽油中掺混10% 和20% 体积分数甲醇燃料的轻型汽油车，在底盘测功机上进行了在中
国国家标准GB18352.3—2005 中规定的Ⅰ型排放试验。使用高效液相色谱仪、气相- 质谱联用仪、
Fourier 变换红外光谱仪分别测量了不同比例甲醇汽油的甲醇、甲醛、乙醛、丙酮、苯、甲苯、二甲
苯等排放。结果表明：使用Fourier 变换红外光谱仪瞬时值积分和袋采化学分析两种方法都能较为
准确地测量汽车尾气中的甲醛、苯、甲苯等排放。随着燃料中甲醇含量的增加，CH4、未燃甲醇和甲
醛排放成比例增加，苯和甲苯排放略有增加，乙醛、丙酮和二甲苯排放基本不变。

Abstract: Unregulated emissions have become an important factor restricting the development of methanol alternative
fuels. Type I emission tests were carried on a chassis dynamometer according to the state standard of China, GB 18352.3-
2005, using a light-duty vehicle fuelled with pure gasoline and gasoline blend with methanol volume fractions of 10% and
20%. High performance liquid chromatography, gas chromatography-mass spectrometry, and Fourier transform infrared
spectrometer (FTIR) were used to measure methanol, formaldehyde, acetaldehyde, acetone, benzene, toluene, xylene and
other unregulated emissions from a vehicle fuelled with different proportions of methanol-gasoline blends. The test results
show that the methods of the integration of FTIR instantaneous values and the chemical analysis of bag sampling can both
accurately measure formaldehyde, benzene, toluene and other unregulated pollutant emissions in the vehicle exhaust. With
increasing methanol content in the fuel, CH4, unburned methanol and formaldehyde emissions increase proportionally, with
the benzene and toluene emissions having a slight increase and acetaldehyde, acetone and xylene emissions remaining
basically the same.

Key words: light-duty vehicle, methanol-gasoline blends, unregulated emissions, measurement methods
