The simultaneous testing of energy consumption and emissions of heavy-duty hybrid Dump Truck was carried out based on the chassis dynamometer. The effects of different working conditions on energy consumption and emissions were analyzed. A Parallel hybrid dump truck with diesel in phase VI of China was selected to test the energy consumption and emissions by using engine mode and hybrid mode respectively under the conditions of CHTC-D and C-WTVC. The results show that compared with pure engine mode, CHTC-D condition of heavy hybrid dump truck has higher energy saving potential than C-WTVC condition, and the energy saving rates are 23.8 % and 18.3 % respectively; For the hybrid mode, the specific emissions of CO2 under C-WTVC and CHTC-D conditions were 1071 g/km and 1010 g/km, respectively.
