| 摘 要： | 为了能具体掌握北京市高里程出租车的实际排放情况,通过随机选取北京市场上正常使用的高里程出租车,按照法规进行排放试验后发现:两种排放阶段的高里程出租车排放因子均超标.国Ⅲ阶段车辆的排放因子对应为:HC,0.37 g/km;NO_x,0.58 g/km;CO,5.77 g/km;国Ⅳ阶段:HC,0.29 g/km;NO_x,0.49g/km;CO,5.35g/km.国Ⅲ排放水平的车辆当里程超过220 000 km后,排放出现急剧劣化;国Ⅳ排放水平的车辆当里程超过180 000 km后,排放出现急剧劣化.相同工况下,车辆热起动排放明显优于冷启动.为有效控制出租车的排放,建议及时更新三效催化器.

| Abstract: | In order to keep informed on the factual emission of the high mileage taxis, some relevant taxis in Beijing were required to attend emission test by means of a random selection. The test results showed that the emission factors of these high mileage taxis all exceeded the standard level. The emission factors corresponding to the National III Emission Standard should be HC 0. 37 g/kin, NOx 0. 58 g/km, CO 5.77 g/km, but those to the National IV Emission Standard are HC 0. 29 g/kin, NOx 0. 49 g/km, CO 5.35 g/km. For the vehicles conforming to the National III Emission Standard, their mileage of deterioration is 220000km, but for those conforming to the National IV Emission Standard, their mileage of deterioration is 180000 km. In order to control the emissions effectively, it is recommended to update the three-way catalytic converters of the taxis in time. |
