南京市机动车排气污染控制和管理对策

简述了南京市机动车排气污染控制和管理对策。对新机动车排气控制实施了新车上牌的环保注册登记目录制，鼓励生产厂家采用先进的排放控制技术，达到国家制定的排放控制目标和排放标准；对在用机动车排气控制实施检测／维护(I／M)制度，对尾气排放不达标车辆进行正常的维修和保养，保证其发动机处于正常技术状况；对高排放污染机动车辆，安装尾气净化装置，以改善机动车排放水平。定期检测中各类型车辆维护前后排气污染物削减结果表明，85％的高排放污染车辆能达标，且CO的削减率最高，达50％左右；定期检测中各类型车辆安装机内净化器前后排气污染物削减结果表明，二次补气机内净化器对CO的净化率为22．5％～30．0％，对HC的净化率为9．7％～30．0％；高能电子点火机内净化器对CO的净化率为5．4％～22．2％，对HC的净化率为17．2％～30．8％。不定期检测中，一些高排放污染车辆安装三元催化反应器后，其净化率可达80％～90％。
