HowEmissionControlWorks
Whenanautomobileengineisrunning,itusesenergygeneratedthroughthecombustionofamixtureofairandfuel.Dependingonwhetheracarisdrivenfastorslowlyorwhethertheengineiscoldorhot,someofthefuel(hydrocarbons)maynotbeburnedcompletely,butmaybedischargedintotheenginecrankcaseorexhaustsystem.Additionalhydrocarbonsmayentertheatmospherethroughevaporationoffuelfromthefueltank.Thesehydrocarbons(HC),whenreleasedintotheair,contributetoundesirablepollution.
Inaddition,carbonmonoxide(CO)andoxidesofnitrogen(NOx)contributetoengineemissions.They,too,areformedduringthecombustionprocessanddischargedintotheexhaustsystem.
