对香港的汽车行驶工况进行了研究.将一套汽车行驶速度和尾气排放浓度的测量系统安装在一辆轻型车上,选择两个代表性路线研究了香港地区的行驶模式.得出了一个基于实际汽车速度的行驶工况,这个行驶工况与美国、日本、欧洲已有的行驶工况有很大不同,建议香港地区车辆排放检测法规中采用该行驶工况.
The driving pattern was studied in Hong Kong along two representative routes using a test van equipped with all the instruments required for recording traffic modes and measuring exhaust emissions of the van.A real\|run based driving cycle has thus been developed to simulate actual driving conditions with respect to exhaust emissions.In comparison with the existing driving cycles of developed countries,the driving cycle has significantly different average speed and relative time spent under acceleration and deceleration.The cycle may be used as a standardized method to evaluate emission level of vehicles and automobile engines and effect of various measures on its improvement.
