Abstract
In Japan, five types of vehicles, light-duty gasoline [(LDG); 550 cc < engine displacement (ED)], super-light-duty gasoline [(SLD); ED < 550 cc], liquid petroleum-fueled [(LPG); 550 cc < ED < 3000 cc], light-duty diesel [(LDD); 550 cc < ED < 5000 cc] and heavy-duty diesel [(HDD); 5000 cc < ED] cars have been used widely to give the complex influences on the hydrocarbon components at roadsides and in city areas, which have not been explained sufficiently. In this study, we investigated the ambient 16 hydrocarbon components at two roadsides in commercial and industrial areas of Osaka City along with the traffic densities of five types of vehicles to propose the significant effects of emissions from SLD and LPG cars besides that of LDG car through a comparison of the ambient [ethylene]/[acetylene] and [i-, n-pentanes]/[i-, n-butanes] ratios with those of the source profiles published in Japan.
在日本,五种类型的车辆,轻型汽油[(LDG);550 cc <发动机排量[ED]、超轻型汽油[SLD];ED & lt;550cc],液态石油燃料[(LPG)];550 cc <ED & lt;3000cc],轻型柴油[(LDD);550 cc <ED & lt;5000cc]和重型柴油[(HDD);5000毫升<汽车的广泛使用对路边和城市地区的碳氢化合物成分产生了复杂的影响,而这些影响尚未得到充分的解释。在本研究中,我们调查了大阪市商业区和工业区两个路边的16种碳氢化合物成分以及五种类型车辆的交通密度,通过将环境[乙烯]/[乙炔]和[i-,正戊烷]/[i-,正丁烷]比例与日本公布的来源概况进行比较,提出了除LDG汽车外,SLD和LPG汽车排放的显著影响。
