HowEmissionControlWorks
Whenanautomobileengineisrunning,itusesenergygeneratedthroughthecombustionofamixtureofairandfuel.Dependingonwhetheracarisdrivenfastorslowlyorwhethertheengineiscoldorhot,someofthefuel(hydrocarbons)maynotbeburnedcompletely,butmaybedischargedintotheenginecrankcaseorexhaustsystem.Additionalhydrocarbonsmayentertheatmospherethroughevaporationoffuelfromthefueltank.Thesehydrocarbons(HC),whenreleasedintotheair,contributetoundesirablepollution.
