Lisebelisoa tsa Diesel Oxidation Catalysts

The diesel oxidation catalyst (DOC) e 'nile ea e-ba karolo ea litsamaiso tsa ho qeta diesel ho tloha ha melaoana e hlahisoa ho fokotsa palo ea mesi e kotsi e lokolotsoeng tikolohong ho tsoa lienjineng tsa disele, ke converter ea matla e etselitsoeng mefuta eohle ea lienjineri tsa diesel le lisebelisoa tsa ho fokotsa Carbon Monoxide (CO), Hydrocarbons (HC) le Phetolelo ea Particulate Matter) carbon le hydrocarbon (PM). ka carbon dioxide (CO2) le metsi. Mesebetsi ea mantlha ea DOC ke oxidation ea CO, li-hydrocarbon tse sa chesoang, le NO, athe hydrocarbon oxidation e sebetsang le eona e ka sebelisoa ho hlahisa li-exotherms tse hlokahalang bakeng sa likarolo tse tlase.

1) E fokotsa tlhahiso ea SOF ka 90%

2)E fokotsa tlhahiso ea CO,HC ho fihla ho 75%, e ka oxidize CO le HC ho CO.₂ le H₂O

3) E thibela oxidation ts'ebetsong ea S le ho fokotsa sebopeho sa sulfate

4) tšepe ea bohlokoa le seaparo sa ho hlatsoa se nang le sebaka se phahameng.

5) Phahamiso e phahameng ea meta.l ea bohlokoa.

6)Lebone le tlase-ho tima mocheso.

7) Kamano e ntle haholo lipakeng tsa-jase le substrate e nang le sebopeho sa marang-rang.

8) Ts'ebetso e ntle ea vibrate.

9) E kopantsoe le sistimi ea EGR ho thusa koloi e fapaneng ho khotsofatsa Euro II kapa Euro III.
