Vim li cas qhov concentration ntawm Urea Solution rau tsheb teeb tsa ntawm 32.5%?
Automotive Urea Solution/AdBlue®/DEF Fluid/AUS 32
(®= sau npe lag luam ntawm Verband der Automobilindustrie eV (VDA).)
Raws li kev sim tiag tiag, qhov chaw khov ntawm Automotive Urea Solution (AdBlue® / DEF Fluid) yog qhov qis tshaj plaws thaum cov ntsiab lus urea yog 32.5%, uas tuaj yeem ncav cuag -11 degree, ua rau nws siv tau ntau dua rau cov huab cua sib txawv thiab cheeb tsam.
Urea Solution rau tsheb (AdBlue® / DEF Fluid) ua haujlwm li cas?
Urea Solution For Vehicle (AdBlue®/DEF Fluid) yog ntxiv rau lub tsheb thauj khoom los ntawm Dispenser rau Urea Solution For Vehicles (AdBlue® / DEF Fluid) lossis ib lub thoob me me qhia cov yeeb nkab. Yog tias nws yog lub tsheb National VI, thaum Urea Solution For Vehicle (AdBlue® / DEF Fluid) ntxiv rau lub tsheb, Urea Solution For Vehicle (AdBlue® / DEF Fluid) zoo sensor yuav kuaj xyuas qhov zoo ntawm Urea Solution Rau Tsheb (AdBlue® / DEF Fluid). Yog tias nws tsis ua raws li tus qauv, yuav muaj lub tswb nrov. Lub sijhawm no, Urea Solution For Vehicle (AdBlue® / DEF Fluid) siv hauv lub tsheb yog nyob rau hauv lub xeev "pw tsaug zog" ntawm lub tsheb loj.
Lub Tsev Siab Siab
Tom qab lub tsheb pib, SCR system tsis pib ua haujlwm tam sim ntawd. SCR system ua tau raws li ob peb yam kev mob: ① lub cav khiav ib txwm; ② Thaum qhov kub hauv lub tank urea siab tshaj -4 degree thiab tsis tau raws li, lub tank urea yuav raug rhuab Tsis muaj kev cuam tshuam txog kev ua haujlwm tom qab; Tom qab cov xwm txheej tau ua tiav, SCR system tuaj yeem nkag mus rau theem tom ntej - lub siab lub tsev theem ib txwm.
Lub npe hu ua lub tsev siab theem yog tsuas yog mus ncig Urea Solution For Vehicle (AdBlue® / DEF Fluid) hauv SCR system pipeline nyob rau hauv siab. Cov theem no ua haujlwm rau ob lub hom phiaj: ① npaj rau kev txhaj tshuaj Urea Solution Rau Tsheb (AdBlue® / DEF Fluid) ncig; ② Txias urea nozzle. Tom qab ua tiav lub tsev siab thiab ruaj khov siab, SCR system nkag mus rau theem tom ntej ua haujlwm - theem txhaj tshuaj.
Thaum lub sij hawm txhaj tshuaj, lub kaw lus yuav suav cov nyiaj txhaj tshuaj thiab lub sijhawm raws li lub cav qhov cua kub, qhov tso pa tawm, cov ntsiab lus nitrogen oxide, thiab lwm yam, thiab hais kom lub nozzle txhaj. Kev txhaj tshuaj ntawm Urea Solution Rau Tsheb (AdBlue® / DEF Fluid) yuav tsum ua kom tau raws li cov xwm txheej hauv qab no: ① Lub siab nyob rau hauv cov kav dej urea rau cov tsheb yuav tsum ua tau raws li qhov yuav tsum tau ua; ② Qhov kub ntawm qhov tso tawm mus txog 200 degrees Celsius; ③ Lub tshuab txhaj tshuaj urea tsis muaj qhov yuam kev; ④ Cov ntsiab lus nitrogen thiab cov pa oxygen hauv cov pa tso pa tawm ntau dua ib qho nqi;
Tom qab txhaj tshuaj Urea Solution Rau Tsheb (AdBlue® / DEF Fluid), urea (CO (NH2) 2) yuav decompose thiab hloov mus rau ammonia gas (NH3) ntawm qhov kub thiab txias. Nitrogen oxides nyob rau hauv lub tshuab hluav taws xob tso tawm nrog ammonia roj los tsim cov roj nitrogen thiab dej. Cov tshuaj tiv thaiv chemical yog:
2CO (NH2) 2+4NH3+O2=2CO2+4N2+4H2O.
Nyob rau theem no, lub hom phiaj ntawm Urea Solution For Tsheb (AdBlue® / DEF Fluid) tau ua tiav.
