摘要

分别做了2种类型重型柴油车的PEMS试验,对环境温度对车辆的实际道路NO_x和PN排放进行了研究,发现低温环境对重型柴油车的整车NO_x排放影响较大,相比于高温环境,低温条件下NO_x总比排放最大增加82.6%,最小增加43.0%;而环境温度对整车PN总比排放的影响趋势无确定结论,主要与整车后处理技术路线和排放标定策略相关性较大。
        PEMS tests of two types of heavy duty diesel vehicles are performed. The influence of environmental temperature on the vehicle's actual road NO_x emissions and PN are studied, and it's found that low temperature had a greater influence on the NO_x emission of heavy duty diesel vehicles. Compared with the high temperature environment, the total NO_x specific emissions increase by 82.6% at most and the minimum increase is 43.0%, on the condition of low temperature. However, there is no definite conclusion on the influence trend of the environmental temperature on PN specific emission of the vehicle, which is mainly related to the afertreatment technical route and the emission calibration strategy of the vehicle.
