Peb-txoj kev catalytic converter muaj cov haujlwm ruaj khov, txhim khu kev qha zoo thiab lub neej ntev. Nws cov khoom siv tau dav siv hauv Toyota, Honda, Buick, Audi, Volkswagen, Hyundai, Suzuki thiab lwm yam qauv.
Cov chaw thauj khoom ntawm peb-txoj kev hloov pauv catalytic yog ib qho ntawm cov khoom siv txeem ntxig cov ntsia rau hauv cov yeeb nkab tso pa tshwj xeeb. Nws hu ua cov cab kuj vim nws tsis koom nrog qhov kev tawm tsam catalytic nws tus kheej, tab sis tau them nrog txheej txheej ntawm cov hlau zoo xws li platinum, rhodium, thiab palladium. Nws tuaj yeem tig HC thiab CO hauv cov pa hluav taws xob rau hauv dej thiab CO2, thiab tib lub sijhawm yauv Nox rau hauv nitrogen thiab oxygen. HC thiab CO yog cov nkev roj lom. Kev nqus tau ntev yuav ua rau tuag taus, thaum NOX ncaj qha ua rau muaj qhov tshwm sim ntawm smog photochemical.
Kev tshawb fawb tau ua pov thawj tias qhov peb-txoj kev hloov catalytic yog txoj hauv kev zoo tshaj plaws los txo cov pa phem no. Los ntawm kev tiv thaiv oxidation thiab txo qis, cov pa roj carbon monoxide yog oxidized rau carbon dioxide, hydrocarbons yog oxidized rau dej thiab carbon dioxide, thiab nitrogen oxides yog txo kom nitrogen thiab oxygen.
Tag nrho peb cov nkaug tsis zoo tau ua cov pa roj. Peb-txoj kev catalyst yuav tsum xav txog ntawm qhov tsawg kawg yog ntsuas kub ntawm 250 degrees Celsius. Thaum twg qhov kub thiab txias tsawg dhau, qhov hloov pauv hloov zuj zus yuav poob tag; thiab cov nquag kub ntawm catalyst (cov ua haujlwm zoo tshaj plaws kub) yog li ntawm 400 ℃ txog 800 ℃, siab dhau lawm yuav ua rau cov catalyst ua kom muaj hnub nyoog txuas ntxiv. Raws li qhov piv txwv huab cua-roj piv (14.7: 1), cov nyhuv ntawm hloov pauv catalytic kuj yog qhov zoo tshaj plaws.
