Despite that commuters spend only 5.5% of their time in cabin vehicles, their exposure to harmful air pollutants, originated from the vehicle itself, and traffic emission is considered significant. In this study, two passenger cars with different type of fuels were investigated in terms of air quality and thermal comfort of their cabin. Investigation was performed in the city of Kozani, Northern Greece. Moreover, air samples near the exhausts were taken, in order to compare concentration of compounds found indoors. Twelve volatile organic compounds and CO were measured inside the cabin when the cars were stopped, when idle and when they were cruising in medium and heavy traffic roads, under various ventilated conditions. Thermal comfort was investigated while driving the cars through the city traffic. Results showed that the air around the diesel exhaust is less affected by emissions from the engine compared to LPG fuel. This is reflected to the TVOC measured into the cabin. Results also revealed that the air quality of a diesel fuel moving car with open windows is only affected by the traffic emissions from neighbouring vehicles, while for the car with LPG fuel, the self-pollution from its own exhaust might contribute together with the outdoor air.
尽管通勤者在车内仅花费 5.5%的时间，但他们暴露于车内自身产生的有害空气污染物和交通排放物中的程度被认为是显著的。在这项研究中，两种不同燃料类型的乘用车在车内空气质量和热舒适性方面进行了研究。该研究在希腊北部科扎尼市进行。此外，还在车辆排气口附近采集了空气样本，以便比较室内发现的化合物的浓度。当汽车在停止、空转和在中等及重型交通道路上巡航时，在各种通风条件下，测量了车内的 12 种挥发性有机化合物和 CO。在城市交通中驾驶汽车时，还研究了热舒适性。结果表明，与 LPG 燃料相比，柴油尾气周围的空气受发动机排放物的影响较小。这反映在测量到的车内总挥发性有机化合物上。结果还表明，开着窗户的柴油燃料移动汽车的空气质量仅受相邻车辆的交通排放物影响，而对于使用 LPG 燃料的汽车，其自身排气的自污染可能与室外空气一起造成影响。
