Khatelopele e kholo ea lipatlisiso e entsoe ts'ebelisong eakhabaneli-catalysts tsa tšepe ho tloseng CO, joalo ka:
4.1 Ho hloekisa mosi oa koloi:khabaneli-catalyst tsa tšepe li sebelisoa haholo ho li hloekisang tsa koloi, tse ka khonang ho tlosa likhase tse kotsi tse kang CO, metsoako ea hydrocarbon (HC) le nitrogen oxides (NOx).Ho phaella moo, bafuputsi ba boetse ba hlahloba motsoako oakhabaneli-catalyst tsa tšepe tse nang le lisebelisoa tse ling tse sebetsang ho ntlafatsa ts'ebetso le botsitso ba li-exhaust purifiers tsa likoloi.
4.2 Tlhoekiso ea moea ka tlung: Tšebeliso eakhabaneli-catalyst tsa tšepe tse hloekisang moea ka tlung li hohetse tlhokomelo e eketsehileng, tse ka khonang ho tlosa CO, formaldehyde, benzene le likhase tse ling tse kotsi tsa ka tlung.Bafuputsi le bona ba ntse ba hlahisa tse nchakhabaneli-catalyst tsa tšepe ho ntlafatsa ts'ebetso, ho fokotsa litšenyehelo le ho fokotsa boholo ba lihloekisi tsa moea tse ka tlung.
4.3 Phekolo ea khase ea flue ea indasteri:khabaneli-catalyst tsa tšepe li na le menyetla e mengata ea ts'ebeliso lefapheng la phekolo ea khase ea liindasteri, tse kang lik'hemik'hale, peterole, tšepe le liindasteri tse ling.Bafuputsi ba ntse ba tsoela pele ho sebetsa hantle le ho tsitsisakhabaneli-catalyst tsa tšepe ho fihlela litlhoko tsa mefuta e fapaneng ea kalafo ea khase ea liindasteri.
