试验车辆和油品对汽车非常规污染物排放影响的试验研究
|
摘要
使用同一种汽油分别在8辆轻型车上,以及在同一辆汽车上分别使用9种汽油,在转鼓试验台上进行了Ⅰ型排放试验,使用傅立叶变换红外光谱方法研究了不同试验车辆和油品参数对汽车非常规污染物排放的影响。结果表明,各辆汽油车的非常规污染物平均排放水平都在同一数量级。各辆试验车辆的常规污染物和非常规污染物排放水平具有较好的一致性。随着汽油品质的变化,试验车辆的非常规污染物平均排放水平也会随着改变,但是变化幅度都不大。不同汽油品质对非常规污染物与常规污染物排放的影响程度基本一致,其中乙醛、1,3-丁二烯、CH_4排放随油样参数改变的幅度较大。
Using one same gasoline on eight vehicles and using a light-duty vehicle fuelled with nine fuels, type I emission tests were carried on a chassis dynamometer. The Fourier transform infra-red spectroscopy method was utilized to research the influences of different light-duty vehicles and fuel quality on unconventional emissions. The results indicate that the average unconventional emissions levels of test vehicles are in the same order of magnitude. The conventional and unconventional emissions have the good consistency. With the variation of the gasoline quality, unconventional emissions of test vehicles change in a slight range. The degrees of influence on conventional and unconventional emission of various gasoline qualities are nearly consistent. Acetaldehyde, 1,3-butadiene and methane emissions have a larger variation with the change of the fuel quality.
