摘要
建立了基于发动机燃烧理论分析的柴油机烟雾排放量计算模型;通过实际道路试验,研究了柴油机烟雾排放的速度特性;通过发动机台架模拟隧道污染环境试验,研究了发动机进气受到污染后对烟雾排放量的影响;采用发动机台架模拟试验探讨了隧道内道路纵坡对柴油车烟雾排放量的影响。研究成果不仅对公路隧道通风方案设计时汽车污染物基准排放量的确定具有一定的指导意义,同时在进行汽车排放对城市污染和公路沿线环境污染评价时可作为计算汽车污染物排放源强的参考。
Based on the analysis of engine combustion theory,an experiment study mathematical model of smog emission amount of diesel is built up.Both on indoor tests and on road tests, the velocity characteristics of diesel smog are studied,and the affects to engine emission amount after engine's inlet pollution air are investigated.By simulating tunnel pollution circumference on indoors engine tests,actual road tests and actual tunnel tests,the affects of the road gradient in tunnel to diesel smog amounts are analyzed.The study results have certain guide significance to determine the criterion emission amount of diesel vehicle during highway tunnel design, but also can be taken as a reference to calculate the intensity of vehicle pollution emission source while estimating vehicle circumstance pollution both in city and around highway.
