I摘要进入21世纪以来，科技不断发展，人民生活水平在逐渐改善，人均经济收入有了显著增长，且呈现稳定增长状态，如今每个家庭生活中几乎都可以见到汽车的身影，汽车出行已经成为了人们必不可少的出行方式。虽然它为人们的出行节省了很多时间，提高了人们的办事效率，使大家的生活变的非常便捷；但是，不能忽视的还有汽车带来的污染。虽然，我国采取了很多严厉的措施来防治汽车污染，但是，随着社会的发展，人们生活水平的提高，可以预见私家车只会越来越多,如果对尾气污染不加控制的话，那么后果难以预料，如何有效的防治汽车污染就变得极其重要。如果能研究一套完善的防治方案，使其在为人们的生活带来便利的同时又不会过多的污染环境，就变得尤为重要。该论文要提出一套较为完善的防治汽车污染的研究方案，通过机内机外控制技术的结合形成一个完整的防治方案，来实现防治汽车污染的目的。此论文主要研究方向为发动机内部净化处理措施，发动机外部尾气净化措施等，并从中提出尾气控制与处理的关键在于包括发动机和新能源等技术的突破与国家与人民对这一问题的态度，最后提出了根据现有的汽车现有量和目前的道路状况以及排放的问题，在行政管理上能解决的一些方法。最后，该论文的研究结果对后期进一步实现燃油汽车的节能减排奠定了一定的基础。关键词：尾气污染；尾气排放；控制现状IIAbstractSincethebeginningofthe21stcentury,withthecontinuousdevelopmentofscienceandtechnology,people'slivingstandardshavebeengraduallyimproved,andthepercapitaeconomicincomehasincreasedsignificantlyandpresentedasteadygrowthstate.Nowadays,almosteveryfamilycanseecarsintheirlife,andcartravelhasbecomeanindispensablewayforpeopletotravel.Althoughitsavesalotoftimeforpeople'stravel,improvespeople'sefficiencyandmakespeople'slifeveryconvenient;However,thepollutionbroughtbycarscannotbeignored.AlthoughChinahasadoptedmanyseveremeasurestopreventandcontrolautomobilepollution,withthedevelopmentofsocietyandtheimprovementofpeople'slivingstandards,itcanbepredictedthatprivatecarswillonlyincrease.Iftheexhaustpollutionisnotcontrolled,theconsequencesareunpredictable,andhowtoeffectivelypreventandcontrolautomobilepollutionbecomesextremelyimportant.Ifwecanstudyasetofperfectpreventionandcontrolplan,makeitbringconveniencetopeople'slife,butnottoomuchpollutionoftheenvironment,itbecomesparticularlyimportant.Thispaperwillputforwardasetofmoreperfectresearchprogramtopreventandcontrolautomobilepollution,throughthecombinationofinternalandexternalcontroltechnologytoformacompletepreventionandcontrolprogram,toachievethepurposeofpreventingandcontrollingautomobilepollution.Thispapermainresearchdirectionfortheengineinternalpurificationmeasures,engineexhaustgaspurificationmeasures,andtoputforwardtailgascontrolandprocessingisthekeytoincludeengineandnewenergytechnologybreakthroughwiththenationalandpeople'sattitudetothisissue,thefinalamountofvehiclesareputforwardaccordingtotheexistingandthecurrentroadconditionsandemissions,somemethodstosolveintheadministrativemanagement.Finally,theresearchresultsofthispaperlayacertainfoundationforfurtherrealizationofenergysavingandemissionreductionoffuelvehicles.Keywords:pollution，emission，controlIII目录第1章绪论.......................................................................................................................41.1课题背景.......................................................................................................................41.2研究的目的和意义......................................................................................................41.3国内外在该方向的研究...
