Kev Pab Cuam Dej ATP Dextron

ATF Dexron kev pabcuam kua dej (Dexron) yog cov khoom lag luam thoob plaws hauv kev lag luam ntawm ntau lub teb chaws thiab nquag siv los ntawm cov tswv ntawm ntau yam ua thiab qauv ntawm cov tsheb. Cov kua dej uas tau teev tseg, uas feem ntau hu ua Dextron lossis Dextron (thiab hauv lub neej niaj hnub no cov npe tsis raug siv dav heev), yog cov dej ua haujlwm hauv kev sib kis tsis siv neeg, lub zog tsav thiab lwm yam kev sib txuas thiab kev sib dhos.

Hauv tsab xov xwm no, peb yuav pom tias Dexron ATF yog dab tsi, qhov twg thiab thaum twg cov kua dej no tau tsim. Tsis tas li ntawd, kev saib xyuas tshwj xeeb yuav raug them rau hom dej no muaj nyob thiab yuav ua li cas muaj ntau hom sib txawv, uas Dextron sau rau hauv kev sib kis tsis siv neeg thiab lwm yam, thiab lwm yam.

Hom thiab hom kua Dexron

Rau qhov pib, hnub no koj tuaj yeem pom cov kua dej los ntawm Dexron 2, Dexron IID lossis Dexron 3 mus rau Dexron 6. Qhov tseeb, txhua hom yog cov kua dej sib cais, feem ntau hu ua Dexron. Txoj kev loj hlob belongs rau General Motors (GM), uas tsim nws tus kheej tsis siv neeg kis dej Dexron nyob rau hauv 1968.

Nco ntsoov tias kev lag luam automotive nyob rau hauv cov xyoo ntawd yog nyob rau theem ntawm kev loj hlob, loj automakers nyob txhua qhov chaw tsim kev kam rau siab thiab cov qauv rau roj thiab kis tau tus mob. Nyob rau hauv lub neej yav tom ntej, cov tolerances thiab specifications tau dhau los ua qhov yuav tsum tau ua rau cov tuam txhab thib peb uas tsim cov kua hauv tsheb.

• Cia peb rov qab mus rau Dextron. Tom qab tso tawm thawj tiam ntawm cov kua dej no, 4 xyoo tom qab, GM raug yuam kom tsim lub cim thib ob ntawm Dextron.

Yog vim li cas yog cov roj whale tau nquag siv los ua kev sib txhuam kev hloov pauv hauv thawj tiam, thiab cov roj iav nws tus kheej sai sai siv tsis tau vim muaj cua sov hauv qhov tsis siv neeg kis. Ib qho qauv tshiab yuav tsum daws cov teeb meem, uas tsim lub hauv paus ntawm Dexron IIC.

Qhov tseeb, whale roj tau hloov nrog jojoba roj raws li kev sib txhuam hloov, thiab cov khoom siv hluav taws xob kuj tau txhim kho. Txawm li cas los xij, nrog rau tag nrho cov txiaj ntsig, qhov muaj pes tsawg leeg muaj qhov cuam tshuam loj heev - corrosion tsis zoo ntawm cov khoom tsis siv neeg kis.

Vim li no, cov tshuaj tiv thaiv corrosion tau ntxiv rau cov kua dej sib kis los tiv thaiv kev ua haujlwm xeb. Cov kev txhim kho no ua rau muaj kev qhia txog Dexron IID cov khoom hauv xyoo 1975. Tsis tas li ntawd thaum lub sijhawm ua haujlwm, nws tau muab tawm tias cov kua dej sib kis, vim yog qhov sib ntxiv ntawm cov khoom siv tiv thaiv corrosion, zoo li khaws cov dej noo (hygroscopicity), uas ua rau cov khoom poob sai.

Vim li no, Dexron IID tau nrawm nrawm nrog kev qhia txog Dexron IIE, uas muaj cov khoom siv ntxiv los tiv thaiv kev ya raws thiab corrosion. Nws yog noteworthy tias cov tiam no ntawm cov kua tau los ua semi-synthetic.

Tsis tas li ntawd, ntseeg tau ntawm kev ua tau zoo, tom qab lub sijhawm luv luv lub tuam txhab tau tsim cov kua dej tshiab nrog kev txhim kho cov yam ntxwv ntawm kev ua lag luam. Ua ntej ntawm tag nrho cov, yog tias yav dhau los tiam muaj ib tug ntxhia los yog semi-synthetic puag, ces tus tshiab Dexron 3 ATF kua yog tsim los ntawm ib tug hluavtaws.

Nws tau raug tsim los hais tias qhov kev daws teeb meem no tiv taus qhov kub thiab txias, muaj lubricating zoo thiab kev tiv thaiv zoo, thiab khaws cov dej ntws ntawm qhov kub qis (txog -30 degrees Celsius). Nws yog lub cim thib peb uas tau dhau los ua neeg thoob ntiaj teb tiag tiag thiab tau siv dav hauv kev sib kis tsis siv neeg, lub zog tsav, thiab lwm yam.

• Txog rau tam sim no, tiam tshiab yog suav tias yog Dexron VI (Dextron 6), tsim los rau Hydra-Matic 6L80 XNUMX-ceev tsis siv neeg kis. Cov khoom tau txais kev txhim kho lubricating zog, txo kinematic viscosity, tsis kam mus foaming thiab corrosion.

Cov chaw tsim khoom kuj tseem tso cov kua dej ua ke uas tsis tas yuav hloov pauv. Nyob rau hauv lwm yam lus, xws li cov roj yog poured rau hauv lub automatic kis tau tus mob rau tag nrho lub neej ntawm chav tsev.

Ntawm chav kawm, nyob rau hauv kev muaj tiag, lub gearbox roj yuav tsum tau hloov txhua txhua 50-60 txhiab kilometers, tab sis nws yog pom tseeb hais tias cov khoom ntawm Dextron 6 tau txhim kho markedly. Raws li kev xyaum qhia, Dextron VI kuj poob nws cov khoom nyob rau lub sijhawm, tab sis nws yuav tsum tau hloov pauv tsawg dua li qhov qub Dextron III.

• Thov nco ntsoov tias cov dej tsis siv neeg kis tau tus mob tau ntev tau tsim los ntawm cov tuam txhab sib txawv, thaum cov khoom tsim los ntawm lub npe Dexron. Raws li GM, qhov kev txhawj xeeb tau tsim tsuas yog cov kua dej no txij li xyoo 2006, thaum lwm cov tuam txhab roj tseem tsim Dextron IID, IIE, III, thiab lwm yam.

Raws li rau GM, lub tuam txhab tsis muaj lub luag haujlwm rau qhov zoo thiab cov khoom ntawm cov kua dej yav dhau los, txawm hais tias lawv tseem ua tau raws li tus qauv Dexron. Nws tseem tuaj yeem raug sau tseg tias niaj hnub Dexron cov kua dej tuaj yeem yog tus qauv lossis HP (kev ua haujlwm siab) rau kev sib kis tsis siv neeg ua haujlwm hauv cov xwm txheej hnyav.

Kuj tseem muaj Dexron Iav Roj rau qhov sib txawv thiab clutches, Dexron Manual Transmission Fluid rau phau ntawv kis, Dexron Dual Clutch Transmission Fluid rau dual-clutch robotic gearboxes, Dexron rau lub hwj chim steering thiab lwm yam khoom thiab mechanisms. Muaj cov ntaub ntawv hais tias General Motors tab tom sim lub cim tshiab ntawm cov kua siv los ua cov roj iav rau CVTs.

Qhov twg Dexron sau rau hauv thiab nws puas tuaj yeem sib xyaw Dexron

Ua ntej, nws yog ib qho tseem ceeb los txiav txim siab seb hom roj twg tuaj yeem thiab yuav tsum tau nchuav rau hauv lub thawv. Cov ntaub ntawv yuav tsum tau nrhiav nyob rau hauv phau ntawv qhia, koj tuaj yeem pom dab tsi yog qhia ntawm cov roj tsis siv neeg kis tau tus mob dipstick.

Yog hais tias lub qia yog cim Dexron III, ces nws yog zoo dua rau ncuav tsuas yog hom no, uas yog ib tug guarantee ntawm ib txwm ua hauj lwm ntawm lub thawv. Yog tias koj sim nrog kev hloov ntawm cov kua pom zoo mus rau lwm yam, ces qhov tshwm sim yog qhov nyuaj rau kwv yees.

Wb mus nyob ntawd. Ua ntej siv ib lossis lwm hom Dexron ATF, koj yuav tsum sib cais los txiav txim siab txog kev nyab xeeb uas lub tsheb yuav nrog kev sib kis tsis siv neeg. GM pom zoo kom siv Dextron IID nyob rau hauv cheeb tsam uas kub tsis poob qis dua -15 degrees, Dextron IIE mus rau -30 degrees, Dexron III thiab Dexron VI mus rau -40 degrees Celsius.

Tam sim no cia peb tham txog kev sib tov. General Motors nws tus kheej ua cov lus pom zoo sib xyaw thiab sib hloov pauv sib cais. Ua ntej, lwm cov roj nrog cov kev qhia tshwj xeeb tuaj yeem muab ntxiv rau lub ntim loj ntawm cov dej sib kis tsuas yog nyob rau hauv cov kev txwv txiav txim siab cais los ntawm cov chaw tsim khoom sib kis.

Tsis tas li ntawd, thaum sib tov, koj yuav tsum tsom mus rau lub hauv paus (synthetics, semi-synthetics, ntxhia roj). Hauv luv luv, qee zaum nws tseem tuaj yeem sib xyaw cov dej ntxhia thiab semi-synthetics, txawm li cas los xij, thaum sib xyaw cov hluavtaws thiab cov roj ntxhia, cov kev xav tsis zoo yuav tshwm sim.

Piv txwv li, yog tias koj sib tov ntxhia Dextron IID nrog hluavtaws Dextron IIE, tshuaj lom neeg cov tshuaj tiv thaiv yuav tshwm sim, cov tshuaj yuav precipitate uas tuaj yeem ua rau tsis siv neeg kis tau tus mob thiab poob ntawm cov kua dej.

Peb kuj pom zoo kom nyeem tsab xov xwm seb cov roj iav puas tuaj yeem sib xyaw. Hauv tsab xov xwm no, koj yuav kawm txog cov yam ntxwv ntawm kev sib xyaw cov roj iav, nrog rau qhov koj yuav tsum xav txog thaum sib xyaw cov roj hauv lub tsheb gearbox.

Tib lub sijhawm, Dextron IID ore tuaj yeem sib xyaw nrog Dextron III. Nyob rau hauv cov ntaub ntawv no, kuj muaj kev pheej hmoo, tab sis lawv yog me ntsis txo, txij li thaum ntau lub sij hawm lub ntsiab additives ntawm cov kua yog zoo sib xws.

Muab qhov sib hloov ntawm Dexron, ces Dexron IID tuaj yeem hloov tau los ntawm Dexron IIE hauv ib qho kev sib kis tsis siv neeg, tab sis Dexron IIE yuav tsum tsis txhob hloov mus rau Dexron IID.

Nyob rau hauv lem, Dexron III tuaj yeem nchuav rau hauv ib lub thawv uas Dexron II kua tau siv. Txawm li cas los xij, kev hloov pauv rov qab (rollback los ntawm Dextron 3 rau Dextron 2) raug txwv. Tsis tas li ntawd, nyob rau hauv rooj plaub uas lub installation tsis muab rau qhov muaj peev xwm ntawm kev txo cov coefficient ntawm kev sib txhuam, hloov Dexron II nrog Dextron III tsis raug tso cai.

Nws yog qhov tseeb tias cov ntaub ntawv saum toj no yog rau kev taw qhia nkaus xwb. Raws li kev xyaum qhia, nws yog qhov zoo tshaj los sau rau hauv lub thawv nrog tsuas yog cov kev xaiv uas cov neeg tsim khoom pom zoo.

Nws kuj tseem siv tau los siv cov analogues, qee qhov txhim kho ntawm tus kheej cov khoom thiab cov ntsuas. Piv txwv li, hloov los ntawm hluavtaws Dexron IIE rau hluavtaws Dexron III (nws yog ib qho tseem ceeb uas lub hauv paus roj thiab lub ntsiab additive pob tseem tsis hloov).

Yog tias koj ua yuam kev thiab ua rau tsis siv neeg kis tau tus mob nrog cov kua dej tsis zoo, cov teeb meem yuav tshwm sim (kev sib txhuam disc plam, viscosity unevenness, siab poob, thiab lwm yam). Qee zaum, clutches tuaj yeem hnav sai sai, yuav tsum tau kho tsis siv neeg kis.

Cia li muab cov ntsiab lus los sib piv

Xav txog cov ntaub ntawv saum toj no, peb tuaj yeem txiav txim siab tias Dexron ATF 3 thiab Dexron VI kis tau tus mob roj yog niaj hnub no muaj ntau yam thiab haum rau ntau qhov kev sib txuas lus tsis siv neeg, lub zog tsav, nrog rau ntau yam khoom thiab cov txheej txheem ntawm GM tsheb.

Peb kuj pom zoo kom nyeem ib tsab xov xwm hais txog dab tsi Lukoil phau ntawv kis tau tus mob roj yog. Hauv tsab xov xwm no, koj yuav kawm txog qhov zoo thiab qhov tsis zoo ntawm Lukoil iav roj rau kev sib kis ntawm phau ntawv, nrog rau dab tsi yuav tsum xav txog thaum xaiv cov khoom no. Txawm li cas los xij, kev zam thiab cov lus pom zoo yuav tsum tau kawm nyias nyob rau hauv txhua rooj plaub, txij li hauv cov thawv qub nws yuav tsis pom zoo kom hloov ntawm Dexron 2 mus rau Dexron 3. Nws tseem ceeb heev uas yuav tsum nco ntsoov tias kev hloov kho mus rau qib siab dua feem ntau yog qhov zoo (los ntawm Dexron IIE rau Dexron3, piv txwv), tab sis feem ntau nws tsis pom zoo kom rov qab los ntawm kev daws teeb meem niaj hnub rau cov khoom qub qub.

Thaum kawg, peb nco ntsoov tias nws yog qhov zoo dua los pib siv cov dej sib kis uas tsim nyog tau teev tseg los ntawm cov chaw tsim khoom, nrog rau kev hloov cov roj hauv kev sib kis tsis siv neeg, lub zog tsav, thiab lwm yam hauv lub sijhawm, txoj hauv kev no yuav zam teeb meem thiab teeb meem cuam tshuam nrog. sib tov, nrog rau thaum hloov ntawm ib hom ATF mus rau lwm qhov.
