Plug-in hybrid electrical vehicles (PHEVs) are generally considered to be a cleaner alternative to conventional passenger cars. However, there is still very limited information available regarding criteria pollutant emissions from these vehicles. This paper shows, for the first time, the emissions of criteria pollutants, unregulated pollutants, and CO and also electric range from two very different PHEVs, one Euro 6 parallel plug-in hybrid and one range-extended battery electric vehicle (BEVx), applying the new world harmonized light-duty test procedure at ambient temperatures equal to 23 and -7 °C. The impact of using a cabin air heating system on vehicle electric range and emissions at cold temperature has also been studied. Cold ambient temperatures and, to a larger extent, the use of heating systems have been shown to lead to a pronounced negative impact on emissions and shorter electric ranges. Results also show that modern PHEVs can emit similar, or even higher, levels of pollutants (e.g., particle number) as Euro 6 conventional gasoline and diesel vehicles.
插电式混合动力汽车（PHEV）通常被认为是传统乘用车的更清洁替代品。然而，关于这些车辆的标准污染物排放的可用信息仍然非常有限。本文首次展示了两种截然不同的插电式混合动力汽车的标准污染物、无管制污染物和一氧化碳排放以及电动续航里程，一种是欧6并联插电式混合动力汽车，另一种是增程式电动汽车（BEVx），在环境温度为23摄氏度和零下7摄氏度的情况下采用新的世界统一轻型车辆测试程序。还研究了在低温下使用车内空气加热系统对车辆电动续航里程和排放的影响。寒冷的环境温度，以及在更大程度上使用加热系统，已被证明会对排放产生显著的负面影响，并缩短电动续航里程。结果还表明，现代插电式混合动力汽车可能排放与欧6传统汽油和柴油车辆相似甚至更高水平的污染物（例如颗粒数量）。
