| 摘要: |
| 为了研究柴油公交车节能减排方法,寻找油耗与排放之间的关系,建立适用于我国柴油公交车的排放模型,以国外广泛使用的综合排放模型(Comprehensive modal emission model,CMEM)中柴油车排放模型为基础,通过对我国柴油公交车与CMEM中的标准柴油卡车的异同点比较,对模型的速度参数、加速度参数、质量参数、传动效率参数等进行修改后,建立适用于我国柴油公交车的排放模型．最后,通过与哈尔滨市某公交线路上公交车实测数据比较,发现所建立的模型计算出的模拟数据与实测数据相差不大,证明所建立改进的CMEM模型可以用于我国公交车排放的模拟计算． |

| Abstract: |
| For the purpose of researching on diesel bus emission, finding out the relationship between oil consumption and emission, and establishing a diesel bus emission model, this paper first studies the diesel truck emission model using CMEM (comprehensive modal emissions model) in foreign countries, then compares the difference between diesel buses in China and standard diesel trucks in CMEM. Some parameters of the model, like speed, acceleration, quality, transmission efficiency and so on are revised, and then the calculating formula which is suitable for diesel buses emissions in China is obtained. It shows that the data calculated by the modified model fits the test data in Harbin city well. |
