The emission characteristics under different operating modes (engine mode and hybrid mode) and different test cycles (C-WTVC and CHTC) of a heavy-duty HEV was studies on the chassis dynamometer and Portable Emissions Measurement System (PEMS), emission performance of the HEV was analyzed in combination of the working condition characteristic parameters. The results show that NOx emission of the test vehicle under hybrid mode is higher than that under engine mode, while the CO emission under hybrid mode is lower than engine mode. Under engine mode, the NOx emission of CHTC is higher than that of C-WTVC. However, under hybrid mode, the NOx emission of CHTC is lower than C-WTVC. Under engine mode, CO emission is concentrated at low speed and low load condition, while under hybrid mode, CO emission is concentrated at high speed and high load condition.
