| Abstract: | Using a set of measuring system installed on a testing vehicle, 15 criterion numbers, which describethe details of vehicle's driving pattern and emission characteristic on real road condition of Tianjin, are obtainedfrom a large quantity of raw data. The results show that the characteristic of driving pattern in Tianjin is verydifferent from that of ECE-15 and FTP-75. That is to say, neither of these two emission testing procedures issuitable in China. A new driving cycle is developed which is accordance with the driving pattern of Tianjin. Thiscycle can be used to evaluate the emission levels of vehicles under real-road condition in laboratory, and can berecommended as a testing procedure used in China. |
