Adblue kua dej. Dab tsi yuav tsum nco ntsoov thaum refueling?
Niaj hnub nimno diesel xyaw yog nruab nrog SCR systems uas yuav tsum tau ua kua AdBlue additive. Nws tsis tuaj yeem ua rau qhov tsis tuaj yeem pib lub tsheb.
AdBlue yog dab tsi?
AdBlue yog lub npe siv los xa mus rau tus qauv 32,5% aqueous tov ntawm urea. Lub npe belongs rau German VDA thiab tsuas yog siv tau los ntawm cov tuam txhab muaj ntawv tso cai. Lub npe nrov rau cov tshuaj no yog DEF (Diesel Exhaust Fluid), uas txhais tau tias xoob ua kua rau cov tshuab hluav taws xob ntawm lub tshuab hluav taws xob. Lwm cov npe pom hauv khw suav nrog AdBlue DEF, Noxy AdBlue, AUS 32 lossis ARLA 32.
Cov tshuaj nws tus kheej, raws li ib tug yooj yim tshuaj, tsis yog patented thiab yog tsim los ntawm ntau manufacturers. Ua los ntawm kev sib xyaw ob yam: urea granules nrog dej distilled. Yog li, thaum yuav cov tshuaj nrog lub npe txawv, peb tsis tuaj yeem txhawj xeeb tias peb yuav tau txais cov khoom tsis raug. Koj tsuas yog yuav tsum kuaj xyuas qhov feem pua ntawm urea hauv dej. AdBlue tsis muaj cov khoom siv ntxiv, tsis raug yoog rau lub cav ntawm cov chaw tsim khoom tshwj xeeb, thiab tuaj yeem yuav ntawm txhua qhov chaw nres tsheb roj lossis khw muag khoom. AdBlue kuj tsis corrosive, teeb meem, flammable los yog tawg. Peb tuaj yeem khaws nws ruaj ntseg hauv tsev lossis hauv tsheb.
Lub tank tag nrho yog txaus rau ob peb lossis ntau txhiab mais, thiab li 10-20 litres feem ntau yog nchuav rau hauv lub tsheb neeg nrog caij. Nyob rau ntawm cov chaw nres tsheb roj koj yuav pom cov dispensers uas ib liter ntawm additive twb raug nqi txog PLN 2 / liter. Qhov teeb meem nrog lawv yog tias lawv tau siv los sau AdBlue hauv cov tsheb thauj khoom, thiab muaj cov khoom ntim tsawg dua hauv cov tsheb. Yog tias peb txiav txim siab yuav cov ntim loj ntawm cov tshuaj urea, tus nqi kuj tseem yuav poob qis dua PLN XNUMX ib liter.
Vim li cas thiaj siv AdBlue?
AdBlue (New Hampshire)3 kuv h2O) tsis yog ib qho roj ntxiv, tab sis cov kua tso rau hauv cov pa tawm. Nyob ntawd, sib xyaw nrog cov pa roj, nws nkag mus rau SCR catalyst, qhov twg nws rhuav tshem tsis muaj teeb meem.x rau dej (chaw), nitrogen thiab carbon dioxide. SCR system tuaj yeem txo NOx 80-90%.
Tsheb nrog AdBlue. Yuav nco tau dab tsi?
Thaum cov kua dej qis qis, lub khoos phis tawj on-board qhia txog qhov yuav tsum tau ua kom nws siab. Tsis tas yuav ntshai, feem ntau "tso tseg" txaus rau ob peb txhiab. km, tab sis, ntawm qhov tod tes, nws kuj tsis tsim nyog ncua sijhawm cov chaw nres tsheb roj. Thaum lub kaw lus pom tias cov kua dej qis lossis cov kua dej ntws tawm, nws tso lub cav rau hauv hom xwm txheej ceev, thiab tom qab lub cav kaw lawm, nws yuav tsis tuaj yeem rov pib dua. Qhov no yog thaum peb tab tom tos rau kev thauj mus los thiab kev mus ntsib kim rau qhov chaw pabcuam. Yog li ntawd, nws tsim nyog sau npe rau AdBlue ua ntej.
Saib thiab; Counter rov qab. Kev ua txhaum lossis kev ua txhaum cai? Lub txim yog dab tsi?
Yog tias nws hloov tawm tias lub cav ECU "tsis pom" qhov tseeb ntawm kev ntxiv cov kua dej, hu rau lub chaw pabcuam kev tso cai lossis chaw ua haujlwm tshwj xeeb. Peb tsis tas yuav ua tam sim ntawd, vim qee lub tshuab txawm xav tau ntau kaum mais ua ntej lawv tuaj yeem ntxiv kua. Yog tias qhov kev mus ntsib tseem yog qhov tsim nyog, lossis peb xav tso siab rau cov khoom ntxiv rau cov kws tshaj lij, tsis txhob yig coj koj tus kheej ntim nrog koj, vim tias tus neeg siv khoom muaj cai nqa nws cov kua rau cov kev pabcuam thiab, xws li ntawm nws tus kheej. lub cev muaj zog roj, thov ib tug refill.
Nws tuaj yeem sib cav seb cov roj uas tau muab yog tsim nyog rau lub cav muab, tab sis AdBlue yeej ib txwm muaj cov tshuaj muaj pes tsawg leeg thiab, tsuav yog nws tsis muaj kab mob los yog urea crystals tau nyob hauv qab, nws tuaj yeem siv rau hauv txhua lub tsheb uas yuav tsum tau muaj. nws siv, tsis hais cov chaw tsim tshuaj paus thiab distributor qhia nyob rau hauv lub pob.
Qhib lub tank thiab sau nws thaum lub cav khiav tuaj yeem tsim cov hnab ntim cua hauv qhov system thiab ua rau lub twj tso kua mis puas. Tsis txhob ntxiv cov kua me me, txog 1-2 litres, vim tias lub kaw lus yuav tsis pom nws. Hauv cov tsheb sib txawv, nws tuaj yeem yog 4 lossis 5 litres.
Saib ntxiv: tig teeb liab. Yuav siv li cas kom raug?
