摘要
功基窗口法一直是我国对在用柴油车进行整车排放测试时评估其污染物排放状况的基本方法。该方法需获取发动机瞬态测试循环功,并通过读取OBD信息获得车辆行驶时发动机做功。但是,在进行在用柴油车符合性抽查时发现上述参数存在难以获取的情况,而发动机最大功率获取相对便捷。通过研究发动机功率与发动机瞬态测试循环功、CO2排放量之间的关系,进而以CO2窗口法替代功基窗口法评估整车污染物排放状况。结果表明,该方法与功基窗口法评价结果基本一致,更便于生态环境主管部门进行在用柴油车符合性检查。
Work-based window method is the basic method used for emissions test of an in-service diesel vehicle in China.To evaluate the emissions level of a vehicle,this method needs to get engine transient test cycle work and to obtain the work done by the engine through reading the OBD information.But it is difficult to obtain the above parameters when checking the emissions conformity of an in-use diesel vehicle,while it is relatively convenient to obtain the maximum engine power.The relationship between engine power and transient test cycle work as well as CO2 emission was studied,and the CO2 window method was proposed to replace the work-based window method for evaluating vehicle pollutant emissions.The results showed that the results of the CO2 window method was consistent with those of the work-based window method,and the CO2 window method was more convenient for an ecological environment department to evaluate the emissions level of diesel vehicles in service.
