IiCatalysts ze-Diesel Oxidation

I-diesel oxidation catalyst (DOC) ibe yinxalenye yeenkqubo zokukhupha i-diesel ukususela ekubeni imimiselo yaziswa ukunciphisa ukukhutshwa kwezinto ezinobungozi ezikhutshiweyo kwindalo evela kwiinjini ze-diesel, i-catalytic converter eyilwe ngokukodwa kuzo zonke iintlobo zeenjini ze-diesel kunye nezixhobo zokunciphisa i-Carbon Monoxide (CO), i-Hydrocarbons (HC) kunye nokuguqula i-Particulate Matter andhydrocarbon (i-PM) i-carbon monoxide (i-PM) kwicarbon dioxide (CO2) nasemanzini. Imisebenzi ephambili ye-DOC yi-oxidation ye-CO, i-hydrocarbons engatshiyo, kunye ne-NO, ngelixa i-hydrocarbon oxidation esebenzayo ingasetyenziselwa ukuvelisa i-exotherms efunekayo kumacandelo asezantsi.

1)Yehlisa ukukhutshwa kweSOF ukuya kuthi ga kwi-90%

2)Yehlisa ukukhutshwa kweCO,HC ukuya kuthi ga kwi-75%, inokwenza i-CO kunye ne-HC kwiCO₂ kunye noH₂O

3) Ukuthintela i-oxidation kwinkqubo ye-S kunye nokunciphisa ukubunjwa kwe-sulfate

4)Intsimbi exabisekileyo kunye ne-washcoat enendawo ephezulu.

5)Ukusasazwa okuphezulu kwe-meta.l exabisekileyo.

6)Ukukhanya okuphantsi{1}}kucime iqondo lobushushu.

7)Ukuncamathela okugqwesileyo phakathi{1}}kwedyasi yokuhlamba kunye nesubstrate enesakhiwo somnatha.

8) Ukusebenza kakuhle kokungcangcazela.

9) Idityaniswe nenkqubo ye-EGR yokunceda isithuthi esahlukileyo ukwanelisa i-Euro II okanye i-Euro III.
