摘　　要：研究针对高海拔WHTC、WHSC测试工况与高原地区用户的实际动力需求不符,提出不同海拔的高原排放测试循环,并比对了不同海拔的当地WHTC与高原WHTC测试循环对污染物检测的异同。结果显示:随着海拔的增加,WHTC、WHSC测试循环工况扭矩降低,用户的动力需求增加,且3000m以上海拔,变化幅度快速增加;采用高原排放测试循环,缩减高海拔扭矩衰减幅度,最大衰减仅为15.1%;对比当地WHTC与高原WHTC测试的CO、HC、NOx排放,其排放规律一致,但存在排放量的差异。In view of the difference between WHTC and WHSC tests at high altitude and the actual power demand of users, the plateau emission test at different altitudes is proposed, and the similarities and differences of pollutant detection between WHTC and WHTC test at different altitudes are compared. The results show that: With the increase of altitude, the torque of WHTC and WHSC test conditions decreases, and the power demand of users increases, and the change range increases rapidly when the altitude is above 3000 m. The high altitude emission test can reduce the torque attenuation range at high altitude, and the maximum attenuation is only 15.1%. Comparison of CO, HC and NOx emissions between local WHTC and plateau WHTC shows that the emission rules are consistent, but there are differences in emissions.
