摘　　要：实际道路排放测试是重型车排放监管的重要手段,为进一步研究实际道路排放测试设备(PEMS)与试验室排放测试设备的差异进行试验。试验包括发动机台架验证试验和整车转毂验证试验。试验过程中将PEMS设备与固定式尾气分析设备串联,对同一尾气进行同时分析,对比CO_(2)和NO_(x)污染物测量结果差异,研究试验室设备与PEMS设备之间的偏差与相关性。Actual road emission testing is an important means of heavy vehicle emission supervision.This test is carried out to further study the difference between actual road emission testing equipment(PEMS)and laboratory emission testing equipment.This test includes engine bench verification test and vehicle drums verification test.During the test,the PEMS equipment was connected in series with the stationary exhaust gas analysis equipment,and the same exhaust gas was analyzed simultaneously,the differences in the measurement results of CO_(2) and NO_(x) pollutants were compared,and the deviation and correlation between the laboratory equipment and the PEMS equipment were studied.
