Litšehetso tsa Catalyst li phetha karolo ea bohlokoa ho fokotsa mocheso oa likoloi, haholo-holo lienjineng tsa diesel.Ha ho le e 'ngoe ea li-catalyst tse fumanehang e sebetsang ka bo eona.Ba hloka sephethephethe ho etsa mosebetsi oa bona hantle.

The DPF catalyst, SCR catalyst, DOC catalyst, le TWC catalyst ke likarolo tse etsang catalytic converter system.Li-catalyst tsa DPF li bapala karolo ea bohlokoa ho tšoasa le ho monya likaroloana tse kotsi tsa khabone mosing oa enjene ea disele.Li-DPF li sebelisa khekhe ea linotši ho tšoasa mosili le likaroloana tsa molora.Li na le li-catalyst tsa tšepe tse entsoeng ka platinum, palladium le lirafshoa tse ling tse sa tloaelehang tsa lefats'e ho matlafatsa tšebetso ea oxidation le ho chesa likaroloana tsa mosili.

SCR catalyst e sebelisa tharollo ea urea e nang le metsi, AdBlue, ho arabela ka diazo oxides tse hlahisoang.Mokhoa ona o kenyelletsa phokotso ea li-nitrogen oxides ho nitrogen le metsi, e leng leano la bohlokoa la ho fokotsa litšila lienjineng tsa diesel.Tharollo ea AdBlue e fafatsoa ka har'a phallo ea khase e tsoang 'me li-oxide tsa naetrojene li arabela ka har'a catalyst ea SCR ho etsa khase ea naetrojene e se nang kotsi.

DOC Catalyst ke motsoako oa oxidation o ikarabellang bakeng sa ho fetola carbon monoxide le hydrocarbons hore e be carbon dioxide le metsi.E etselitsoe ho etsa oxidize likaroloana tsena tse silafatsang hore e be tse se nang kotsi.

Qetellong, TWC catalyst ke mokhoa oa litsela tse tharo o fetolang carbon monoxide e kotsi, nitrogen oxides le hydrocarbons hore e be carbon dioxide e se nang kotsi le metsi.Li-catalyst tsa TWC li sebelisoa hangata lienjineng tsa peterole 'me li sebetsa hantle ho feta li-catalyst tsa DOC.

Li-catalyst tse hlalositsoeng ka holimo li hloka tšehetso ho sebetsa ka katleho.Tšehetso ea li-catalyst ke karolo ea bohlokoa ea tsamaiso ea li-converter, e thusa ho tšoara lintho tse silafatsang, ho li fetola lintho tse se nang kotsi, 'me ho bohlokoa ka ho fetisisa, e ntlafatsa bokhoni ba enjene.Ts'ehetso e sebetsa joalo ka sebopeho sa ts'ehetso bakeng sa li-catalyst tsa tšepe 'me e bohlokoa bakeng sa ho eketsa sekhahla sa karabelo.E boetse e etsa hore catalytic converter e tšoarelle nako e telele.

Ts'ebetso ea catalyst e itšetlehile ka tšehetso ea eona.Litšehetso tse entsoeng ka tsela e sa nepahalang li ka tsoa kapa tsa koala liphaephe tsa mosi, tsa sitisa ho tšoara likaroloana, tsa sitisa tšebetso ea lik'hemik'hale, kapa tsa senya lisebelisoa.Ka hona, ho bohlokoa ho khetha thepa e loketseng ea tšehetso, joalo ka alumina, silicon carbide kapa ceramics.

Qetellong, sistimi ea catalytic converter ke karolo ea bohlokoa ea koloi ea sejoale-joale.Li-catalyst tsa DPF, li-catalyst tsa SCR, li-catalyst tsa DOC, le li-catalysts tsa TWC li sebetsa 'moho le ts'ehetso ea ho etsa mesebetsi ea bona ka nepo.Litšehetso li bapala karolo ea bohlokoa ho ts'oara litšila tse silafatsang le ho etsa hore li-catalyst li sebetse hantle ho eketsa ts'ebetso ea enjene, ho fokotsa mesi le ho ntlafatsa ts'ebetso ea tikoloho.Ho bohlokoa ho khetha thepa e tsamaisang thepa e nepahetseng ho netefatsa hore sesebelisoa sa hau sa ho fetolela se tla sebetsa hantle le ho fana ka ts'ebeletso ea nako e telele.
