Kugwiritsa Ntchito Rare Earth mu Kuyeretsa Kwa Galimoto Yotulutsa Mafuta

Pofika kumapeto kwa 2021, China ili ndi magalimoto opitilira 300 miliyoni, pomwe magalimoto amafuta amapitilira 90%, yomwe ndi mtundu wofunika kwambiri wagalimoto ku China. Pofuna kuthana ndi zoipitsa wamba monga nitrogen oxides (NOx), ma hydrocarbons (HC) ndi carbon monoxide (CO) muutsi wagalimoto wamafuta, "chothandizira njira zitatu", ukadaulo wodziwika bwino wothamangitsa mafuta agalimoto, wapangidwa. , yogwiritsidwa ntchito ndikusinthidwa mosalekeza. Tekinoloje yomwe yangodziwika kumene ya petulo in-cylinder direct injection (GDI) ipangitsa kuti pakhale mpweya woipa kwambiri (PM), womwe umapangitsa kuti pakhale ukadaulo wamafuta a petulo (GPF). Kukhazikitsidwa kwa matekinoloje omwe ali pamwambawa kumadalira kwambiri kapena kuchepera pakutenga nawo gawo kwa njira zaku China - zachilendo padziko lapansi. Pepalali limayang'ana kaye kakulidwe kamitundu yosiyanasiyana yaumisiri woyeretsera utsi wamafuta amafuta, kenako ndikuwunikanso momwe amagwiritsira ntchito komanso zotsatira za zinthu zachilendo zapadziko lapansi (makamaka cerium dioxide) m'njira zitatu zosungirako okosijeni, chonyamulira / chowongolera chitsulo chabwino komanso galimoto yamafuta. particles fyuluta. Zitha kuwoneka kuti ndi chitukuko ndi luso lamakono la zipangizo zatsopano zapadziko lapansi, teknoloji yamakono yoyeretsa galimoto ya petulo ikukhala yowonjezereka komanso yotsika mtengo. Pomaliza, pepalali likuyembekezera chitukuko cha zinthu zosowa zapadziko lapansi zoyeretsera utsi wagalimoto, ndikuwunikanso mfundo zazikuluzikulu ndi zovuta pakukweza kwamtsogolo kwa mafakitale ogwirizana nawo.
