Guhindura Catalitike

Intangiriro kuri iki gicuruzwa:

Iwacuinzira eshatuya autos ikoresha ibyuma cyangwa ceramique nkuwitwara, ukongeraho ubwikorezi-budasanzwe-isi ya coupound oxyde nkibikoresho byifashishwa hamwe nigitigiri gito cyibyuma byagaciro, bityo amaherezo bigacumita nyuma yuburyo bwihariye bwo gutwikira.Ibicuruzwa ntabwo byateganijwe kugabanuka.

Cataliseri yakoresheje byimazeyo ingaruka zoguhuza ibyuma byagaciro hamwe na okiside idasanzwe yisi-ku isi, bitewe na Carbone Oxide (CO), Hydrocarbon (HC) na Oxynitride (Nox) muri gaze yumurizo wa moteri iba oxyde kandi yanduye.Muri ubu buryo, ibyuka bihumanya bitatu bihinduka Dioxyde de Carbone (CO2), H2O na Azote bitangiza ikirere.

Nyuma yamasaha 100 yintebe yo gusaza byihuse mu ishami ry’ubwubatsi bw’imodoka muri kaminuza ya Tsinghua, igipimo cyo guhindura ibice bya CO, HC na Nox ni 96.3%, 94% na 90.5%.Ubushyuhe bwo hasi bwa mbere bwo gutwika bwa catalizator ni 235 ℃, 272 ℃ na 230C ℃ bwazamutseho 45 ℃, 53 ℃ na 40 ℃, ugereranije na catalizator nshya nyuma yo gusaza hamwe na coefficient yo gusaza ni 1.2 bikwiranye.Nyuma yo kugeragezwa kuri autos, byagaragaye ko yujuje EuⅡEmission Standard.

Hamwe n’ishyirwa mu bikorwa rya Eu Standard Ibipimo by’ibyuka bihumanya ikirere hamwe na Eu Standard Ibicuruzwa byangiza ikirere mu Bushinwa, Isosiyete yateje imbere ibiyigize kandi ishyiraho urutonde rw’ibikoresho bishya bifite ubushyuhe buke bwo gutwika mu nda, uburyo bwiza bwo guhindura ibintu hamwe n’ibipimo birwanya imbaraga mu gucumura hanyuma bigasaba Patente y’igihugu. yo guhanga.Guhindura moteri ukurikije gahunda ya CCC + UCC cyangwa UCC ituma ibigize gaze umurizo byujuje Eu Standard Ibipimo byangiza ikirere na EU Standard Ibipimo by’ibyuka bihumanya.Mu mwaka wa 2006, hagenzuwe ibigize gaze umurizo mu kigo cy’igihugu gishinzwe kugenzura ubuziranenge bw’imodoka kandi cote ya CO, HC na Nox yari 1.0g / km, 0,6g / km na 0.08g / km, yari yahuye na Eu Ⅲ Ibipimo byangiza ikirere.
