基于远程监控数据和3-Bin MAW方法对国六标准在用柴油车的实际运行工况和NOx排放特征进行研究。结果表明:在实际行驶中,柴油车近半数时间处于低负荷工况,怠速和中高负荷工况的运行时长占比相近,在怠速Bin、低负荷Bin和中高负荷Bin时,柴油车的NOx排放贡献率分别为334%、495%和171%;在怠速Bin时,约862%的车辆NOx排放速率低于20 g/h的区间排放限值;在中高负荷Bin时,约992%的柴油车比排放低于092 g/(kW·h)的区间排放限值;在低负荷Bin时,仅约523%的车辆比排放能够低于054 g/(kW·h)的排放限值。 |

An study was conducted on actual running conditions and NOx emission characteristics of diesel vehicles that met national phase Ⅵ motor vehicle pollutant emission standards by using remote monitoring data and 3 Bin MAW method. The results showed that during actual driving, diesel vehicles were in low load conditions for nearly half of the time, and the proportions of running time in idling and medium high load conditions were similar. In idling Bin, low load Bin and medium high load Bin, the contribution rates of NOx emissions from diesel vehicles were 334%,495%,and 171%, respectively. In idling Bin, approximately 862% of the vehicles had NOx emissions lower than the prescribed emission limit of 20 g/h. In medium high load Bin,nearly 992% of the diesel vehicles had NOx emissions lower than the prescribed emission limit of 092 g/(kW·h). In low load Bin, only about 523% of the vehicles had emissions lower than the emission limit of 054 g/(kW·h). |
