I-substrate ye-honeycomb yesinyithi sisixhobo esisisiseko esineembobo ze-honeycomb esenziwe ngeqokobhe lentsimbi engagqwaliyo kunye ne-corrugated FeCrAl alloy foil ngenkqubo yokuwelda nge-coil. Isetyenziselwa ikakhulu ukuxhasa ii-catalytic coatings (Pt, Pd, Rh) okanye ukusebenza njengezinto eziphambili zokutshintshiselana ngobushushu, ezisetyenziswa kakhulu ekucoceni umphunga weemoto, unyango lwegesi yenkunkuma yemizi-mveliso, ukhuseleko lobushushu be-aerospace kunye neminye imimandla.
Yenziwe nge-FeCrAl alloy foil, i-metal honeycomb substrate inesakhiwo esixineneyo, esifana ne-honeycomb ene-micro-channels ezifanayo—esebenza njenge-"catalytic reactor" yokucocwa kwegesi ephumayo. Igcwele ii-catalytic coatings kunye nee-noble metals (Pt, Pd, Rh) kwaye inokumelana okuhle kakhulu nobushushu obuphezulu, okuvumela ukusebenza okuzinzileyo phantsi kobushushu obugqithisileyo bokukhupha. Xa i-exhaust gas enobushushu obuphezulu idlula kwezi channels zincinci, ii-noble metal catalysts zibangela ii-chemical reactions eziguqula ungcoliseko oluyingozi lube zizinto ezingenabungozi, kunye nee-reactions eziphambili ngolu hlobo lulandelayo:
1. I-carbon monoxide oxidation:2CO + O₂ = 2CO₂
2. I-oxidation ye-hydrocarbon:2CxHy + (2x+y/2)O₂ = 2xCO₂ + yH₂O
3. Ukunciphisa i-nitrogen oxide:2NOx = N₂+ xO₂
Ngokudluliselwa kobushushu ngokukhawuleza, uxinzelelo oluphantsi lomqolo kunye nokumelana okunamandla kokungcangcazela, isetyenziswa kakhulu ekucoceni umphunga ozenzekelayo kunye nonyango lwegesi yenkunkuma yemizi-mveliso.

Ii-UAV, iijenereyitha eziphathwayo, iinjini ezincinci zaselwandle, oomatshini abancinci bezolimo, ii-ATV kunye nezixhobo zamandla eziphathwayo (ukufakelwa okuncinci, ungcoliseko oluphantsi lokukhupha umsi).
2. Ubungakanani obuphakathi (ububanzi obuyi-80-150mm, ubude obuyi-100-200mm, ubude obuyi-100-400 cpsi):
Iimoto zabakhweli, izithuthi zorhwebo ezilula (ii-catalytic cores ezineendlela ezintathu), izandisi ze-EV range, i-hybrid exhaust kunye neejenereyitha ezincinci ezingxamisekileyo (uxinzelelo oluphantsi lomqolo, ubushushu obukhawulezayo).
3. Ubukhulu obukhulu (ububanzi obuyi-180-300mm, ubude obuyi-200-400mm, ubude obuyi-100-200 cpsi):
Iilori ezinzima, izithuthi zobunjineli, igesi yenkunkuma yemizi-mveliso, umsi wolwandle, ukucocwa kwegesi yolwelo kunye negesi yokutshisa (umthamo omkhulu womsi wokukhupha).
4. Ubungakanani obukhethekileyo obenzelwe wena (obungacwangciswanga, >300mm ububanzi/>400mm ubude, 60-600 cpsi):

Ewe ngokwenene. Singenza ngokwezifiso izinto ezininzi njengoko kubonisiwe ngezantsi:
1. Ubungakanani kunye neMilo: Ububanzi obunokulungiselelwa (30mm ~ 500mm +), ubude (50mm ~ 400mm +), kunye nemilo (isangqa esiqhelekileyo, iimilo ezikhethekileyo ezingaqhelekanga) ukuze zilingane neendawo ezahlukeneyo zokufakela izixhobo.
2. Ubuninzi beeSeli: Ingahlengahlengiswa ukusuka kwi-60 cpsi ukuya kwi-600 cpsi, ihambelana neemfuno ezahlukeneyo zokucocwa kunye nokulungiswa kwezixhobo ezahlukeneyo (izixhobo zamandla ezincinci, unyango lwegesi yenkunkuma yemizi-mveliso, inqwelo-moya).
