在底盘测功机上测试了25辆乘用汽车（10辆传统汽油发动机汽车、10辆配备三元催化器的车辆和5辆柴油发动机车辆）。使用特氟隆过滤器和XAD 2吸附器在定容采样系统中收集废气。多环芳烃的鉴定和定量进行了高分辨率的Shpol'skii分光荧光法超过两个INRETS周期（城市和道路周期）的真实世界的驾驶条件下，热或冷启动。以μ g/km为单位的结果显示了三种技术：-平均速度的影响-催化剂的效率，在热启动和冷启动下-传统汽油发动机汽车的排放量较高，特别是在冷启动和低速条件下。
Twenty five passenger cars (10 conventional petrol engined cars, 10 vehicles equipped with a 3-way catalyst and 5 diesel engined vehicles) were tested on a chassis dynamometer. Exhaust gases were collected in a Constant Volume Sampling system using Teflon filter and XAD2 adsorber. Identification and quantification of PAHs were carried out by high resolution Shpol'skii spectrofluorometry over two INRETS cycles (urban and road cycles) representative of real-world driving conditions under hot or cold start. The results obtained in mu g per km exhibit for the three technologies :-the influence of average speed -the efficiency of catalyst, under hot and cold start -higher emissions by conventional petrol engined cars, particularly under cold start and low speed conditions.
