Indlela ezintathu zokukhuthaza

Isigaba I

Njengoko umgangatho wokukhutshwa kwe-NOX uphuculwe, i-Pt kunye ne-Rh catalysts ziye zavela njengoko amaxesha afuna.Le catalyst inokuthi ngaxeshanye ihlambulule i-carbon monoxide, i-hydrocarbons kunye ne-oxides ye-nitrogen, ngoko ibizwa ngokuba yi-three-way zero catalyst Olu luphando lwe-/indlela ezintathu ze-0 catalyst.Nangona kunjalo, le catalyst ifuna inani elikhulu leentsimbi ezixabisekileyo ezifana nePt kunye neRh;Iyabiza kwaye ithanda ukutyhefeka ilothe.Ngoko ke, ayifanelekanga izithuthi ezisebenzisa i-petroli ekhokelayo.

Isigaba II:

I-Pt kunye ne-Rh zitshintshwe ngokuyinxenye yi-Pd ukunciphisa iindleko ze-catalyst.Lungiselela/indlela ezintathu ze-0 catalyst kunye ne-Pt, i-Rh, i-Pd njengomzimba oyintloko.Iyakwazi ukuhlambulula i-CO, i-HC kunye ne-NO ngexesha elifanayo.Iinzuzo zayo ngumsebenzi ophezulu, umphumo omuhle wokuhlanjululwa, ubomi obude, kodwa ixabiso eliphezulu.Isetyenziswa kakhulu kumazwe angaphandle;

Inqanaba lesithathu:

Yonke i-palladium catalyst.Imodeli eluncedo ineenzuzo zokuhlanjululwa kwangaxeshanye kwe-CO, i-HC kunye ne-NOX, ixabiso eliphantsi, ukuzinza kwe-thermal ephezulu kunye nokukhanya okukhawulezayo kweempawu.

Kuphela ngokulawula ngokuchanekileyo umlinganiselo we-air-fuel ngaphakathi kwefestile emxinwa (ngokubanzi i-14.7 ± 0.25) kufuphi nomlinganiselo wethiyori we-air-fuel apho izinto ezintathu ezingcolisayo zinokuhlanjululwa ngaxeshanye.
