对一辆轻型货车在不同位置和不同行驶条件下车内外的氮氧化物和一氧化碳浓度进行了为期6个月的测量。为了研究汽车乘客暴露于指定的室外污染物，室内外空气质量（IO）的关系，在不同的驾驶条件下，即交通密度，通风模式和道路类型进行了研究。选择了四种主要的驾驶环境：公路、乡村、城市街道和隧道。车辆在三种主要类型的通风条件下行驶：带空气再循环的空调，带新鲜空气进气的空调。研究发现，IO比不仅与通风方式有关，还与驾驶环境有关。当车辆在不同的环境中行驶时，即使使用相同的通风模式，IO值也会发生显著变化。结果发现，使用新鲜空气通风模式，IO可以从大约0.5-3，因为它通勤从高速公路到农村。结果还表明，随着交通密度的增加，室内NO水平增加。自然通风汽车的室内NO浓度随室外NO浓度的变化而变化，IO值在0.5 ~ 5之间变化。结果还表明，即使在空调货车，室内NO和CO浓度显着影响的室外。建议在不同环境下通勤时采用不同的通风方式。(C)2003爱思唯尔有限公司。保留所有权利。
Nitrogen oxides and carbon monoxide concentration were measured inside and outside of a light-goods-vehicle at different locations and driving conditions for a 6-month period. To investigate the exposure of the vehicle passenger to the specified outdoor pollutant, the indoor-outdoor air quality (IO) relationships under various driving conditions, namely traffic density, ventilation modes and type of roadway were studied. Four main types of driving environments were selected: highway, countryside, urban street and tunnel. The vehicle was driven under the three main types of ventilation conditions: air-conditioning with air-recirculation, air-conditioning with fresh air intake. and natural ventilation.It is found that the IO ratio is not specific only to the mode of ventilation but also depends on the driving environment. The IO value can vary drastically even using the same ventilation mode when the vehicle is travelling in a different environment. It is found that using fresh-air ventilation mode, the IO can change from approximately 0.5-3 as it commutes from a highway to the countryside. The results also indicate that indoor NO level increased as the traffic density increases. The fluctuation of indoor NO level of naturally ventilated vehicle followed the variation of outdoor NO concentration with the IO value varying from 0.5 to 5. The results also show that even in an air-conditioned van, the indoor NO and CO concentration is significantly affected by that outdoor. It suggests the use of different ventilation mode when commuting in different environment. (C) 2003 Elsevier Ltd. All rights reserved.
