重型柴油车污染物排放综述

A Review of Pollutant Emissions from Heavy-Duty Diesel Vehicles

通过对比国内外排放法规,从实际道路测试、台架测试和模型测算等三个方面展开关于重型柴油车污染物排放的研究。研究发现,无论是从排放法规还是排放标准,我国均与欧美国家存在差距。同时,也发现高原环境对重型柴油汽车的排放有很大的影响,并且找出了我国重型柴油车目前存在的问题,可为后续的发展和研究提供参考。

A study on the emission of heavy-duty diesel vehicles was carried out by comparing the emission regulations at home and abroad,from three aspects,including actual road tests,bench tests and model calculations.It is found that there is a gap between China and Europe and the US in terms of emission regulations and standards.It is also found that the plateau environment has a great influence on the emissions of heavy-duty diesel vehicles,and the current problems of heavy-duty diesel vehicles in China are identified,which can provide reference for the subsequent development and research.
