摘　　要：基于便携式排放测试系统,在不同试验路线下对国Ⅵ重型柴油车进行了PEMS试验研究。研究表明,不同试验路线下,整车排放结果与法规的符合性存在差异,高速道路连续爬坡行驶对PN排放影响较大。研究结果对提高重型柴油车排放监管的科学性,开发稳定可靠的道路测试及评价方法具有一定参考意义。Based on the portable emissions measurement system PEMS,PEMs test was carried out on national VI heavy duty diesel vehicle under diff erent test routes.The results show that the compliance of vehicle emission results with the regulations is diff erent under diff erent test routes,and continuous climbing on high-speed road has great infl uence on PN emission.The research results have certain reference signifi cance for improving the scientifi city of heavy duty diesel vehicle emission regulation and developing stable and reliable road test and evaluation methods.
