（1.Shanghai V olkswagen Co.,Ltd.;2.Shanghai Jiaotong University;）【Abstract】The structural characteristics and layout of a new parallel-series hybrid electric vehicle were analyzed, and its main control strategies were introduced. Based on the vehicle dynamics theory, the basic parameters of powertrain system of the parallel-series hybrid electric vehicle were calculated, and the power performance under the working conditions of Chinese typical urban drive cycle were analyzed, then the simulation model was established and the power performance and fuel economy were calculated. The simulation results show that compared with the original bus, power performance and fuel economy have been improved considerably by using this new dynamic system..

【Abstract】Emission characteristic of main components of NO, NO2 and N2O, etc.

for a kind of direct injection diesel engine that is fuelled with five biofuels that blended with different mixing ratio is analyzed. The results show that the NO x emissions of different biodiesel blends shows no great differences, and as load increases, the differences become relatively greater; whereas the NO emission increase as load increases, NO2 emission is comparatively low during low and high load, while it is highest during medium load; N2O is mainly generated during low load; while during mid and high load, it is approximately zero; as the blending proportion of biodiesel increases, the NO x and NO emission increase greatly, while NO2 emission decreases.
