Ntawm cov neeg tsav tsheb hauv tebchaws Russia, qhov kev tsis sib haum xeeb ntawm cov tsheb nrog diesel fais fab nroj tsuag tau nce tas li. Muaj ntau qhov laj thawj rau qhov no. Piv txwv li, feem ntau cov tsheb zoo li no tau yuav vim lawv qhov ua tau zoo. Tsuas yog diesel roj yog pheej yig dua li cov roj av zoo tib yam. Koj tuaj yeem ua kom muaj kev ntseeg siab ntawm lub zog cog nrog Q8 roj, tsim tshwj xeeb rau cov cav tov diesel. Dab tsi yog qhov zoo tshaj plaws los siv thiab nws cov txiaj ntsig yog dab tsi?
Ob peb lo lus hais txog hom
Q8 hom nws tus kheej yog tswv los ntawm Kuwaiti lub xeev roj thiab roj tuam txhab. Lub tuam txhab muaj concentrated ntau lawm, tsheb thauj mus los thiab ua cov hydrocarbons. Yog li ntawd, nws muaj peev xwm txo tau cov nqi ntawm cov roj lubricants tsim thiab txhim kho lawv cov khoom zoo. Qhov kev txhawj xeeb ntawm cov chaw tsim khoom tau txais daim ntawv pov thawj thoob ntiaj teb ISO 9002, ISO 9001 thiab QS 9000. Lub tuam txhab tau qhib nws lub chaw tshawb fawb hauv Tebchaws Europe, qhov twg cov roj nplua nyeem tshiab tau tsim thiab cov qauv raug sim. Lub hom phiaj muaj tag nrho cov kev pom zoo tsim nyog los ntawm cov tuam txhab tsheb loj (BMW, Renault, Volvo thiab lwm tus).
Bestseller
Q8 Formula Excel roj tau dhau los ua tus muag khoom zoo tshaj plaws hauv qeb ntawm cov roj nplua nyeem rau cov tshuab hluav taws xob diesel. Qhov sib tov no nrov heev nrog cov neeg nyiam tsheb thoob ntiaj teb.
Nature oil
Cov roj cav diesel uas tau nthuav tawm yog nyob rau hauv qeb hluavtaws. Hauv qhov no, cov khoom siv hydrocarbon hydrocracking yog siv los ua lub hauv paus. Cov khoom yog ntxiv txhim khu kev qha los ntawm ib tug complex ntawm alloying additives. Nrog lawv cov kev pab, nws muaj peev xwm nthuav dav cov yam ntxwv ntawm kev sib tov ntawm lub sijhawm. Txhim kho qhov zoo ntawm qhov muaj pes tsawg leeg thiab nws lub neej kev pab cuam.
rau qhov cav
Q8 roj yog tsim rau turbocharged lossis ib txwm aspirated diesel xyaw. Nws tuaj yeem siv rau ob qho tib si qub qauv ntawm lub cav, thiab ntawm cov niaj hnub tshaj plaws nruab nrog cov roj txhaj ncaj qha.
Viscosity
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm cov roj cav diesel yog nws cov viscosity. Kev faib tawm raws li qhov ntsuas no yog thawj zaug los ntawm Association of Automotive Engineers of America (SAE). Qhov nthuav tawm hom Q8 roj tau tshaj tawm qhov ntsuas 5W40. Koj tuaj yeem tso cov dej sib tov los ntawm qhov system ntawm qhov kub ntawm -35 degrees Celsius. Nyob rau tib lub sijhawm, kev nyab xeeb txias pib ntawm lub cev muaj zog tuaj yeem nqa tawm ntawm -25 degrees. Ib qho yooj yim-ntws Q8 roj cav yog tsim rau ob lub caij ntuj no thiab lub caij ntuj sov ua haujlwm.
Txhawm rau tswj qhov xav tau viscosity ntawm qhov sib txawv ntawm qhov kub thiab txias, polymeric hydrocarbons tau ntxiv rau qhov sib tov. Macromolecules ntawm cov tebchaw hloov lawvzoo nyob ntawm qhov kub thiab txias. Piv txwv li, thaum cov cua sov sab nraud raug txo qis, lawv tau ntim rau hauv ib qho kev muab kauv, uas ua rau nws muaj peev xwm tswj tau qhov xav tau viscosity thiab ntom. Thaum rhuab, cov txheej txheem rov qab tshwm sim. Qhov tseeb yog tias cov macromolecules nthuav dav, thiab cov fluidity ntawm cov muaj pes tsawg leeg tau pom zoo txo.
Q8 roj ntawm hom no kuj muaj qhov qis qis. Qhov sib tov hardens ntawm -39 degrees Celsius. Ua li no, cov tebchaw tau nkag mus rau hauv cov muaj pes tsawg leeg uas txo qhov loj ntawm paraffin crystals uas precipitate nrog qhov kub thiab txias.
tiv thaiv corrosion
Qhov kom zoo dua ntawm cov roj diesel no kuj yog cov khoom lag luam muaj ntau qhov sib npaug ntawm phosphorus, sulfur thiab halogen compounds. Cov tshuaj no tsim cov yeeb yaj kiab thinnest nyob rau saum npoo ntawm lub cav, uas tiv thaiv kev sib cuag hlau nrog cov tshuaj lom neeg ua phem. Yog li ntawd, nws muaj peev xwm neutralize cov kev pheej hmoo ntawm corrosion kis mus rau saum npoo. Qhov no muaj txiaj ntsig zoo rau lub neej ntawm lub tshuab fais fab.
Tshem tawm cov pa roj carbon deposits
Q8 roj kuj tseem muaj ntau ntawm ntau yam tshuaj detergent additives. Qhov tseeb yog tias cov roj diesel yog tus cwj pwm los ntawm kev nce ntxiv ntawm sulfur compounds. Thaum kub hnyiab, lawv tsim cov tshauv, uas tuaj yeem nyob rau sab nrauv ntawm cov khoom siv hluav taws xob. Los ntawm qhov no, lub vibration ntawm lub cev muaj zog nce, ib tug yam ntxwv khob tshwm, thiab roj noj nce. Magnesium thiab barium tebchaw yog siv los ua cov tshuaj ntxuav tes hauv Q8 roj ntawm hom no. Cov khoom puas tsuajtsim los soot agglomeration tiv thaiv tom qab coagulation ntawm cov tebchaw.
Kev ruaj ntseg ntawm cov khoom
Cov roj tsheb tau raug cuam tshuam rau qhov tsis zoo tshaj plaws los ntawm cov pa oxygen radicals hauv huab cua. Cov tebchaw no oxidize lub Cheebtsam ntawm lub lubricant, hloov cov tshuaj formula ntawm lub lubricant. Lawm, qhov no muaj kev cuam tshuam tsis zoo rau cov yam ntxwv ntawm cov khoom. Cov txheej txheem tsis zoo no tuaj yeem tiv thaiv tau ua tsaug rau phenols thiab aromatic amines nkag mus rau hauv cov roj nplua nyeem. Cov khoom sib txuas uas nthuav tawm ntxiab dawb radicals ntawm atmospheric oxygen, tiv thaiv cov txheej txheem oxidative.
Txo kev sib txhuam thiab txuag roj
Kev siv roj Q8 kuj txo cov roj noj. Qhov nruab nrab, roj noj yog txo los ntawm 5-8%. Qhov no tau ua tiav los ntawm kev siv ntau yam molybdenum tebchaw. Cov tshuaj tsim cov yeeb yaj kiab muaj zog ntawm qhov chaw ntawm lub zog cog, uas txo cov kev sib txhuam loj heev. Nws kuj tiv thaiv kev hnav ntxov ntxov ntawm cov khoom siv hluav taws xob.
Ua haujlwm ntawm qhov kub siab
Qhov kub siab, siab RPMs thiab siv cov viscosity additives ua rau muaj feem ua npuas ncauj. Yog li ntawd, kev faib cov roj nplua nyeem nyob rau saum npoo ntawm qhov chaw ntawm lub tshuab fais fab yuav tsis ruaj khov. Qhov tshwm sim yog ceev lub cav hnav. Txhawm rau tiv thaiv qhov tsis zoo no hauv Q8 roj, tus nqi ntawm silicon tebchaw tau nce. Lawv rhuav tshem cov huab cua npuas, ua rau kom qhov nro ntawm cov roj. Nws yog qhov zoocuam tshuam qhov adhesion ntawm cov khoom xyaw.
