应用何种评估方法才能买到既环保、节油又满足城市需要的公交客车,一直是公交客运企业非常关注的问题。本文通过让参与竞标的客车在中国典型城市公交循环工况下行驶,使用车载排放测试仪器对其测试,最后计算出比功率油耗量、比功率排放量等道路实际指标来判定客车在经济性能和排放性能方面的差异。然后根据整车设计、价格等多方面评价指标共同决定哪家竞标成功。 What kind of assessment method can be used to buy a bus that is both environmentally friendly, fuel efficient and meets the needs of the city has always been a major concern for bus passenger transport companies. In this paper, the bidding buses are driven in the bus cycle of typical cities in China, and tested by vehicle emission test equipment. Finally, the actual road indexes such as specific fuel consumption and specific power emissions are calculated to determine whether the bus is in economic performance and Differences in emissions performance. Then according to vehicle design, price and other aspects of the evaluation of indicators to determine which bidding success.
