Khoom Taw Qhia
SCR catalyst feem ntau yog siv los txo NOx hauv diesel cav tso nrog Urea-SCR tshuab. Diesel SCR catalyst feem ntau muab faib ua Vanadium raws SCR (V-SCR) catalyst thiab Molecular sieve raws li SCR catalyst.
Lub V-SCR catalytic converter tuaj yeem ua tau raws li Euro IV & Euro V emission qauv rau diesel xyaw ntawm txoj kev, thiab Euro IV emission qauv rau off-road me me thiab nruab nrab lub zog diesel xyaw; Molecular sieve SCR catalyst tuaj yeem muab faib ua Cu-SCR, Fe-SCR thiab Copper- iron composite SCR, uas feem ntau yog siv rau lub cav diesel ntawm txoj kev kom tau raws li Euro VI emission standardand rau off-road kom tau raws li Euro VI thiab saum toj no emission qauv. .
