摘要
介绍了机动车排放检测新技术简易工况法的检测原理、检测方法、检测设备及其技术特点,通过进行怠速法、双怠速法、简易工况法的实车对比测试,证明了简易工况法比现行国家标准怠速法的技术更先进和有效,它能模拟实际路况反映汽车尾气排放的污染程度,能区分在用车中的高排放车、超标率和达标车,根据检测数据辅助不合格车辆进行有效的治理。以减低机动车污染物的排放,增强机动车的性能,配合I/M制度的实施。
This paper introduces the principle, method, equipment and characteristic of the Acceleration Simulation Model, which is a new technique for testing vehicle exhaust-gas. By holding contrastive tests between Idle cycle, Dual-idle cycle and Acceleration Simulation Model, the Acceleration Simulation Model proves more advanced and efficient than the Idle cycle model of Chinas state standard. 揂cceleration Simulation Model?can imitate the real situation to reflect the concentration level of vehicular pollutants,of distinguishing the vehicle of high concentration level,and exceeding standard rate,and the vehicle of up to standard from the in-use vehicle.According to data of determination, it help the vehicle of down below standard have a valid treatment. It would achieve the purpose of reducing the exhaust gas of the vehicle, of improving the function of the vehicle, of matching the I/M system.
