AutomobileEmissions:AnOverviewEmissionsfromanindividualcararegenerallylow,relativetothesmokestack(烟囱)imagemanypeopleassociatewithairpollution.Butinnumerouscitiesacrossthecountry,thepersonalautomobileisthesinglegreatestpolluter,asemissionsfrommillionsofvehiclesontheroadaddup.Drivingaprivatecarisprobablyatypicalcitizen'smost"polluting"dailyactivity.

Thepowertomoveacarcomesfromburningfuelinanengine.Pollutionfromcarscomesfromby-productsofthiscombustion(燃烧)process(exhaust)andfromtheevaporation(蒸发)ofthefuelitself.

Gasolineanddieselfuelsaremixturesofhydrocarbons(碳氢化合物),compoundswhichcontainhydrogenandcarbonatoms.Ina"perfect"engine,oxygenintheairwouldconvertallthehydrogeninthefueltowaterandallthecarboninthefueltocarbondioxide.Nitrogen(氮)intheairwouldremainunaffected.Inreality,thecombustionprocesscannotbe"perfect",andautomotiveenginesemitseveraltypesofpollutants.

TypicalEngineCombustion:

FUEL+AIR=>UNBURNEDHYDROCARBONS+NITROGENOXIDES+CARBONMONOXIDE+CARBONDIOXIDE+WATER

HYDROCARBONS

Hydrocarbonemissionsareproducedwhenfuelmolecules(分子)intheenginedonotburnorburnonlypartially.Hydrocarbonsreactinthepresenceofnitrogenoxidesandsunlighttoformground-levelozone(臭氧),amajorcomponentofsmog.Ozoneirritatestheeyes,damagesthelungs,andaggravatesrespiratoryproblem.Anumberofexhausthydrocarbonsarealsotoxic,withthepotentialtocausecancer.

NITROGENOXIDES(NOx)

Underthehighpressureandtemperatureconditionsinanengine,nitrogenandoxygenatomsintheairreacttoformvariousnitrogenoxides,collectivelyknownasNOx.Nitrogenoxides,likehydrocarbons,areprecursorstotheformationofozone.Theyalsocontributetotheformationofacidrain.

CARBONMONOXIDE

Carbonmonoxide(CO)isaproductofincompletecombustionandoccurswhencarboninthefuelispartiallyoxidized(氧化)ratherthanfullyoxidizedtocarbondioxide(CO2).Carbonmonoxidereducestheflowofoxygeninthebloodstreamandisparticularlydangeroustopeoplewithheartdisease.

CARBONDIOXIDE

Inrecentyears,theU.S.EnvironmentalProtectionAgency(EPA)hasstartedtoviewcarbondioxide,aproductof"perfect"combustion,asapollutionconcern.Carbondioxidedoesnotdirectlyimpairhumanhealth,butitisa"greenhousegas"thattrapstheearth'sheatandcontributestothepotentialforglobalwarming.

Hydrocarbonpollutantsalsoescapeintotheairthroughfuelevaporation.Withtoday'sefficientexhaustemissioncontrolsandadvancedgasolineformulations,evaporativelossescanaccountforamajorityofthetotalhydrocarbonpollutionfromcurrentmodelcarsonhotdayswhenozonelevelsarehighest.Evaporativeemissionsoccurinseveralways:

DIURNAL(每日的):Gasolineevaporationincreasesasthetemperaturerisesduringtheday,heatingthefueltankandventinggasolinevapors.

RUNNINGLOSSES:Thehotengineandexhaustsystemcanvaporizegasolinewhenthecarisrunning.

HOTSOAK:Theengineremainshotforaperiodoftimeafterthecaristurnedoff,andgasolineevaporationcontinueswhenthecarisparked.
