我国汽车尾气排放控制现状与对策(毕业论文)

湖北汽车工业学院毕业论文I摘要随着社会的进步，国家经济的发展，汽车作为社会的主要交通工具，它的保有量在急剧增加，在一定程度上给人民的生活带来了方便，同时也给环境造成了污染。汽车尾气处理排放对环境的影响是与日巨增，而尾气排放超标的问题不但是政府关注的事物，也是百姓常谈的焦点。在日常生活中，我们好像随时可以遇到这样的问题。因此，汽车尾气处理技术就变成了非常棘手的问题。去年中国社科院发布的《中国低碳经济发展报告》，指出从科学角度和国际视点解读雾霾现象，分析危害、雾霾成因并提出对策。基于京津冀区域原生排放的PM2.5的来源的调查分析，该地区PM2.5的主要排放源为：机动车排放和道路扬尘所占比例50%，工业排放的占比例37%，居民化石燃料燃烧和电厂排放占10%左右。本文的目在于帮助大家了解汽车尾气的巨大危害性，增强对环境的保护意识，并且积极参与到控制汽车尾气排放的行列中来。关键词：尾气，排放，标准，新能源湖北汽车工业学院毕业论文IIAbstractAlongwithsociety'sprogress,thestateeconomydevelopment,theautomobiletooksocialthemaintransportationvehicle,itsinventoryinthesharpgrowth,gavepeople'slifetobringtoacertainextentconveniently,simultaneouslyhasalsocausedthepollutiontotheenvironment.Theautomobileexhaustprocessingemissionstheinfluenceisincreasesgreatlytotheenvironmentwiththedate,notonlybuttheexhaustemissionsexceedingtheallowedfigurequestionisathingwhichthegovernmentpaysattention,alsoisthecommonpeopleordinaryremarksfocalpoint.Inthedailylife,wemaymeetsuchquestionprobablyasnecessary.Therefore,theautomobileexhaustprocessingtechnologyturnedtheextremelythornyquestion.LastyeartheChineseSocialScienceInstituteissuedChineseLow-carbonEconomyDevelopmentReport,pointedoutfromthescientificangleandtheinternationalviewpointexplanationfoghazephenomenon,theanalysisharm,thehazeoriginandproposedthecountermeasure.BasedontheBeijingandTianjinHubeiregionprimaryemissionsPM2.5origindiagnosis,thislocalPM2.5mainemissionssourceis:Thevehicleemissionsandthepathraisethedusttoaccountforproportion50%,theindustrialemissionaccountforproportion37%,inhabitantfossilfuelburningandthepowerplantemissionsaccountforabout10%.Thisarticleitemliesinhelpseverybodyunderstandingautomobileexhaustthehugehazardousnature,strengthenstotheenvironmentprotectionconsciousness,andparticipatesinthecontrolautomobileexhaustemissionspositivelyintheranks.Keyword:Exhaust,emissions,standard,newenergy湖北汽车工业学院毕业论文III目录摘要.............................................................................................................................................IAbstract...................................................................................................................................II目录..........................................................................................................................................III1我国汽车尾气排放现状......................................................................................................11.1我国现有的汽车保有量............................................................................................11.2汽车尾气的主要污染物及其危害............................................................................22汽车尾气排放标准..............................................................................................................42.1国内与国外汽车尾气排放标准的比较....................................................................42.2我国汽车尾气排放标准的实施................................................................................53减少汽车尾气排放的具体措施和方法..............................................................................73.1新能源汽车的研发与发展........................................................................................73.1.1混合动力车......................................................................................................73.1.2纯电动车..........................................................................................................83.1.3燃料电池汽车..................................................................................................83.1.4氢动力汽车......................................................................................................93.1.5燃气汽车..........................................................................................................93.1.6生物乙醇汽车................................................................................................103.2控制汽车尾气排放技术..........................................................................................103.2.1汽车环保生物节能膜....................................................................................103.2.2分子共振技术................................................................................................113.2.3汽车尾气路面讲解技术................................................................................113.2.4汽车尾气的催化净化....................................................................................113.3提升燃油品质..........................................................................................................12总结与展望..............................................................................................................................13致谢..........................................................................................................................................14参考文献..................................................................................................................................15湖北汽车工业学院毕业论文11我国汽车尾气排放现状1.1我国现有的汽车保有量改革开放以来，随着国家的综合国力的增强，经济社会的发展，人民的生活越来越好，生活水平也在不断地提高，汽车快速进入千家万户，近十年汽车年均增加1100多万辆。根据公安部提供的数据，截至2013年底，我国汽车保有量达到了1.37亿辆，是2003年汽车保有量的5.7倍，占全部机动车比率达到54.
