Keeb kwm ntawm urea los yog Diesel Exhaust Fluid
Urea lossis Diesel Exhaust Fluid (DEF) yog tsim feem ntau hauv cov lus teb rau nitrogen oxide (NOx) cov pa phem tawm los ntawm lub tshuab diesel. Nitrogen oxide yog ib qho ntawm cov pa phem uas tsim nyob rau hauv cov txheej txheem diesel cav combustion, uas muaj teeb meem loj rau ib puag ncig thiab tib neeg kev noj qab haus huv. Txhawm rau tswj thiab txo cov pa phem no, tsoomfwv thiab cov koom haum ib puag ncig tau tsim cov qauv nruj thiab cov kev cai, ua rau cov tuam txhab tsim tsheb tau txais kev tswj hwm kev tswj hwm cov pa phem.

Environmental pollution challenges
Huab cua tsis zoo: Nitrogen oxides yog ib qho tseem ceeb ntawm huab cua phem, uas tuaj yeem tsim smog thiab acid nag, cuam tshuam rau huab cua zoo.
Kev pheej hmoo rau kev noj qab haus huv: Kev raug mob mus ntev rau qhov siab ntawm NOx tuaj yeem ua rau muaj teeb meem kev noj qab haus huv xws li kab mob ua pa thiab kab mob plawv.
Kev hloov pauv huab cua: NOx kuj koom nrog kev tsim cov ozone hauv huab cua, uas cuam tshuam rau kev hloov pauv huab cua.
Regulatory tsav
Cov txheej txheem thoob ntiaj teb, xws li Euro VI tus qauv hauv Tebchaws Europe thiab EPA 2010 tus qauv hauv North America, tau teeb tsa kev txwv nruj rau cov pa nitrogen oxide.
Kev ua raws cai: Yuav kom ua tau raws li cov kev cai tswj hwm no, cov tuam txhab tsim tsheb yuav tsum tau txais cov thev naus laus zis tshiab thiab cov khoom siv, thiab cov tshuaj urea (DEF) yog ib qho tseem ceeb rau kev ua tiav cov hom phiaj no.
cov khoom xyaw
Urea: High purity urea, tsim 32.5% ntawm cov tshuaj.
Deionized dej: dej ntshiab, accounting rau 67.5% ntawm kev daws.
Cia thiab siv
Cia tej yam kev mob: Khaws rau hauv qhov chaw txias, qhuav kom deb ntawm tshav ntuj ncaj qha thiab qhov kub thiab txias (siab dua 30 degree lossis qis dua -11 degree ).
Siv cov kev cai: Xyuas kom muaj kev siv cov tshuaj purity urea siab kom tsis txhob muaj kev puas tsuaj rau SCR system, thiab tsis tu ncua xyuas thiab ntxiv cov tshuaj urea.
Kev tshuaj xyuas tsis tu ncua: Kev tshuaj xyuas tsis tu ncua ntawm SCR system thiab kev siv tshuaj urea kom ntseeg tau tias kev ua haujlwm ntawm lub cev thiab ua raws li cov qauv emission.

Kev tshwm sim thiab kev siv cov urea lossis tail gas kho kua yog ib qho tseem ceeb ntawm txoj kev loj hlob ntawm niaj hnub diesel cav technology nyob rau hauv teb rau nce stringent ib puag ncig cov kev cai thiab cov qauv. Los ntawm kev siv thev naus laus zis SCR, adblue kua Exhaust Fluid cov kev daws teeb meem tsis tsuas yog txo cov nitrogen oxide emissions los ntawm diesel xyaw, tab sis kuj pab cov tuam txhab tsheb ua kom muaj roj ntau dua thiab txo nqi khiav lag luam, yog li nrhiav kev sib npaug ntawm kev tiv thaiv ib puag ncig thiab kev lag luam.
