Nhoroondo ye Catalytic Converter
Nhanganyaya yechigadzirwa ichi:
Yeduthree way catalystyemotokari inoshandisa simbi kana ceramic semutakuri, ichiwedzera iyo yakazvigadzira isingawanzo-ivhu coupound oxide sechinhu chekuwedzera uye chishoma chesimbi dzinokosha, nekudaro inozopedzisira yanyungudutswa mushure mekuita kwakakosha kupfekedza.Ichi chigadzirwa hachina kuraswa kuderedza.
Iyo catalyst yakashandisa zvizere kurongeka kwesimbi yakakosha uye isingawanzo-yepasi coupound oxide, pasi pesimba reiyo Carbon Oxide (CO), Hydrocarbon (HC) uye Oxynitride (Nox) mugasi remuswe weautos inoiswa oxidized uye. deoxidized.Nenzira iyi, zvitatu zvinosvibisa zvinoshandurwa kuita Carbon Dioxide(CO2), H2O neNitrogen izvo zvisingakuvadzi kumhepo.
Mushure memaawa zana ebhenji kukurumidza kuchembera bvunzo mudhipatimendi reinjiniya yemotokari yeTsinghua University, mafractional ekushandura CO, HC uye Nox ari 96.3%, 94% uye 90.5% zvichiteerana.Kudzikira kwekutanga kupisa tembiricha yecatalyst ndeye 235 ℃, 272 ℃ uye 230C ℃ iyo yakakwira ne45 ℃, 53 ℃ uye 40 ℃ zvichiteerana, zvichienzaniswa nezvinokonzeresa mushure mekuita kuchembera uye kuchembera coefficient iri 1.2 zvinoenderana.Mushure mekuedzwa pamotokari, zvakaratidza kuti zvakasangana neEuⅡEmission Standard.
Nekumisikidzwa kweEu Ⅲ Emission Standard uye Eu Ⅳ Emission Standard muChina, Kambani yakakwenenzvera chinongedzo uye yakagadzira nhevedzano yezvitsva zvinokonzeresa zvine yakaderera intial yekupisa tembiricha, yakanyanya kutendeuka inogoneka uye yakakwirira inodzivirira index pasi pekuisa uye ndokunyorera kuNational Patent. yekugadzira.Iko kugadziridzwa kweinjini zvinoenderana neCCC + UCC kana UCC Chirongwa chinogonesa chinongedzo chemuswe gasi kusangana neEu Ⅲ Emission Standard uye EU Ⅳ Emission Standard.Muna 2006, chinhu chegasi remuswe chakaongororwa munzvimbo yenyika yekuongorora mhando dzemotokari uye makotendi eCO, HC neNox aive 1.0g/km, 0.6g/km uye 0.08g/km zvakateerana, izvo zvakasangana neEu Ⅲ. Emission Standard.
