Zothandizira za Catalyst zimagwira ntchito yofunika kwambiri pakuchepetsa kutulutsa kwa magalimoto, makamaka mu injini za dizilo.Palibe chothandizira chomwe chilipo chimagwira ntchito pachokha.Amafuna chonyamulira kuti agwire ntchito yawo moyenera.

Chothandizira cha DPF, chothandizira cha SCR, chothandizira cha DOC, ndi chothandizira cha TWC ndi zigawo zomwe zimapanga makina osinthira othandizira.Zothandizira za DPF zimagwira ntchito yofunikira pakutchera ndi kuyamwa tinthu tating'ono ta kaboni muutsi wa injini ya dizilo.Ma DPF amagwiritsa ntchito zisa kuti azitchera mwaye ndi phulusa.Muli ndi zitsulo zopangira zitsulo zopangidwa ndi platinamu, palladium ndi zitsulo zina zosowa zapadziko lapansi kuti zipititse patsogolo ma oxidation ndikuwotcha tinthu ta mwaye.

Chothandizira cha SCR chimagwiritsa ntchito njira yamadzimadzi ya urea, AdBlue, kuti igwirizane ndi ma diazo oxides otulutsidwa.Dongosololi limaphatikizapo kuchepetsa ma nitrogen oxides kukhala nayitrogeni ndi madzi, njira yofunika kwambiri yochepetsera zowononga mu injini za dizilo.Njira ya AdBlue imapopera mu mpweya wotulutsa mpweya ndipo ma nitrogen oxides amachitira mu chothandizira cha SCR kuti apange mpweya wosavulaza wa nayitrogeni.

Chothandizira cha DOC ndi chothandizira cha okosijeni chomwe chimatembenuza mpweya wa carbon monoxide ndi ma hydrocarbon kukhala carbon dioxide ndi madzi.Amapangidwa kuti apangitse oxidize tinthu tating'ono toyipa izi kukhala zopanda vuto.

Pomaliza, chothandizira cha TWC ndi chothandizira chanjira zitatu chomwe chimasintha carbon monoxide yoyipa, ma nitrogen oxides ndi ma hydrocarbon kukhala mpweya woipa komanso madzi.Zothandizira za TWC zimagwiritsidwa ntchito kwambiri pamainjini amafuta ndipo ndizothandiza kwambiri kuposa zopangira za DOC.

Zothandizira zomwe zafotokozedwa pamwambapa zimafuna chithandizo kuti zigwire bwino ntchito.Thandizo lothandizira ndi gawo lofunikira la makina osinthira, limathandizira kutenga zowononga, kuzisintha kukhala zinthu zopanda vuto, ndipo koposa zonse, zimathandizira kuyendetsa bwino kwa injini.Thandizoli limagwira ntchito ngati chothandizira zopangira zitsulo ndipo ndizofunikira kwambiri pakuwonjezera momwe zimachitikira.Zimapangitsanso chosinthira chothandizira kukhala cholimba.

Kuchita kwa chothandizira kumadalira chithandizo chake.Zothandizira zopangidwa molakwika zimatha kuthawa kapena kutseka mapaipi otulutsa utsi, kulepheretsa kugwidwa kwa tinthu, kulepheretsa kusintha kwamankhwala, kapena kuwononga zoyambitsa.Chifukwa chake, ndikofunikira kusankha zida zoyenera zothandizira, monga aluminiyamu, silicon carbide kapena zoumba.

Pomaliza, chothandizira chosinthira makina ndi gawo lofunikira lagalimoto yamakono.Zothandizira za DPF, zothandizira za SCR, zothandizira za DOC, ndi zothandizira za TWC zimagwira ntchito limodzi ndi chithandizo chothandizira kuti akwaniritse ntchito zawo moyenera.Zothandizira zimagwira ntchito yofunika kwambiri potsekera zowononga ndikupangitsa kuti zoyambitsa zigwire bwino ntchito kuti injini igwire bwino ntchito, kuchepetsa kutulutsa mpweya komanso kukonza zachilengedwe.Kusankha zinthu zonyamulira zoyenera ndikofunikira kuti muwonetsetse kuti makina anu osinthira othandizira azigwira ntchito bwino ndikukupatsani ntchito yayitali.
