Beddelka Catalytic
Hordhaca alaabtan:
Oursaddex jid kicinBaabuurta waxay shaqaaleysiisaa biraha ama dhoobada sida sideha, iyagoo ku daraya is-sameeyay ee naadirka-dhulka coupound oxide sida walaxda dheeriga ah iyo qadar yar oo macdan qaali ah, sidaas awgeed ugu dambeyntii waa la miiray ka dib habka daahan gaarka ah.Alaabtan looma dejin in la dhimo.
Kiciyahu waxa uu si buuxda u isticmaalay saamaynta isuduwidda biraha qaaliga ah iyo naadirka-earth coupound oxide, oo ay hoos yimaadaan saamaynta kaarboon Oxide (CO), Hydrocarbon (HC) iyo Oxynitride (Nox) ee gaaska dabada ee autos waa oksaydh iyo deoxidized.Sidan, saddexda wasakh ayaa loo beddelaa Kaarboon Dioxide (CO2), H2O iyo Nitrojiin kuwaas oo aan waxyeello u geysan hawada.
Kadib 100 saacadood oo kursiga keydka ah ee imtixaanka gabowga degdega ah ee waaxda injineerinka baabuurta ee Jaamacadda Tsinghua, heerarka beddelka jajabka ee CO, HC iyo Nox waa 96.3%, 94% iyo 90.5% siday u kala horreeyaan.Heerkulka ugu hooseeya ee dabka bilowga ah ee kicinta waa 235 ℃, 272 ℃ iyo 230C℃ kuwaas oo kor u kacay 45℃, 53℃ iyo 40℃ siday u kala horreeyaan, marka la barbar dhigo kicinta cusub ka dib falcelinta gabowga iyo isku dheelitirka gabowga waa 1.2 si waafaqsan.Ka dib markii lagu tijaabiyay baabuurta, waxay caddaysay inay buuxisay heerka EuⅡ Emission Standard.
Iyadoo la fulinayo heerka Eu Ⅲ Emission Standard iyo Eu Ⅳ Heerka Emission ee Shiinaha, Shirkaddu waxay hagaajisay walaxda waxayna soo saartay taxane cusub oo kiciyaal ah oo leh heerkulka hore ee dabka hoose, waxtarka beddelka sare iyo tusaha adkaysiga sarreeya ee hoos yimaada sintering ka dibna codsatay Patentka Qaranka ikhtiraacida.Hagaajinta matoorada iyadoo loo eegayo barnaamijka CCC+UCC ama UCC waxay awood u siinaysaa walaxda gaasta dabada inay la kulanto heerka Eu Ⅲ Emission Standard iyo EU Ⅳ Emission Standard.Sannadkii 2006, walaxda gaasta dabada ayaa lagu baadhay xarunta qaranka ee tayada baabuurta iyo CO, HC iyo Nox waxay ahaayeen 1.0g/km, 0.6g/km iyo 0.08g/km siday u kala horreeyaan, kuwaas oo la kulmay Eu Ⅲ Heerka sii daynta
