【摘要】 提出了一种无需环境参数修正的地区机动车排放因子计算模型,改善由修正参数引入的模型不确定度。对模型的原理、结构和排放因子计算流程进行了阐述,证明该模型除需对机动车使用状态参数进行补偿外,无需对环境参数进行补偿。对沈阳市小型轿车和小型客车的日均排放因子进行了计算,并与COPERT-V模型计算结果进行了对比,证明了该模型的优越性,并证明满载状态下小型客车的人均尾气排放因子低于小型轿车。更多还原

【Abstract】 A novel vehicle emission calculation model named Regional Vehicle Emission Model( RVEM) was proposed based on vehicle emission detection system and database in China,which could calculate regional vehicle emission factor without considering the corrections of environmental parameters influence,for which uncertainties of model caused by corrections of environmental parameters influence could be reduced. Then,the theory,structure and the process of emission parameters calculation were introduced in detail,and it was proved that corrections caused by environmental parameters influence but not the vehicle utilized condition needn’t be consider,and then the process of average speed correction parameter calculation was introduced. Based on the proposed RVEM emission calculation model,the vehicle emission factors of car and micro-bus in Shenyang were calculated and compared with the results of the results of COPERT-V model,which not only prove the superiority of RVEM,but also prove that the per capita vehicle emission factors of car was higher than the one of micro-bus.更多还原
