BMW 7 series cav
Txheem
BMW 7-Series yog ib lub tsheb xis nyob, uas tau pib rov qab rau xyoo 1979 thiab txuas ntxiv mus txog Lub Ib Hlis 2019. Lub 7 Series cav tau dhau los ua ntau yam kev hloov pauv nyob rau lub sijhawm ua haujlwm ntev, tab sis tau tsim lawv tus kheej ua cov chaw txhim khu kev qha, ua pov thawj qhov kev xav ntawm German zoo thiab kev ntseeg siab.
Lub ntsiab lus luv luv ntawm cov chav nyob ntawm txhua tiam ntawm BMW 7-Series
Ib qho tshwj xeeb ntawm BMW 7-Series xyaw yog lawv cov ntim loj, tsawg kawg yog ob litres. Uas thaum lub sijhawm ua haujlwm tau mus txog qib 6,6 litres, piv txwv li, ntawm M760Li AT xDrive hloov kho, restyling ntawm 6th tiam 2019. Tab sis cia peb pib nrog thawj lub cav nruab rau thawj tiam ntawm lub tsheb no, uas yog M30B28.
M30V28 yog cov roj av uas muaj qhov ntim ntawm 2788 cm3, nrog lub zog siab tshaj plaws ntawm 238 horsepower thiab roj noj txog li 16,5 litres ib 100 km. 6 lub tog raj kheej muab lub zog ntawm 238 N * m ntawm 4000 rpm. Nws yuav tsum tau qhia meej tias lub cav M30B28 kuj tau teeb tsa rau thawj tiam 5 Series BMW tsheb, thiab tau paub tias yog "millionaire", tab sis nrog kev siv roj ntau dhau. Peb tuaj yeem hais li cas yog tias cov tsheb nrog M30B28 cav tseem tsav ntawm peb txoj kev?
Tom qab qauv ntawm lub cav M80B30 tau txais kev nce ntawm 200 cm3 thiab 2 lub tog raj kheej. Lub zog tseem nyob hauv 238 horsepower thiab noj 15,1 litres ntawm AI-95 lossis AI-98 roj av tau txo qis me ntsis. Zoo li lub M30B28 chav tsev, lub cav no tau nruab rau ntawm BMW thib tsib series thiab tau lees paub tias yog ib qho ntawm cov kev ntseeg siab tshaj plaws hauv lub ntiaj teb tsheb.
Tab sis BMW 7-Series restyling ntawm 6 tiam ntawm Lub Ib Hlis 2019 tau nruab nrog ntau lub cav, suav nrog cov diesel B57B30TOP nrog ntxaib turbocharging thiab cov ntaub ntawv roj noj ntawm 6,4 litres. Lub tsheb tsim 400 horsepower thiab lub zog ntawm 700 N * m ntawm 3000 rpm. Thiab qhov no tsuas yog ib chav nyob nruab rau ntawm 6th tiam restyling, ntxiv rau roj av B48B20, diesel N57D30 thiab lwm yam cav.

Cov teeb meem tshwm sim nrog BMW 7-Series cav
BMWs yog cov tsheb nrog "lab-duas" cav, tab sis qee qhov teeb meem yuav nrog cov tswv ntawm cov tsheb no thoob plaws lub sijhawm ua haujlwm. Yog li ntawd, nws yog ib qho tsim nyog yuav tau npaj rau lawv los yog ceeb toom ua ntej los ntawm kev ua haujlwm zoo raws sij hawm thiab siv cov khoom siv kim heev.
- Rau lub tog raj kheej sab hauv combustion engines ntawm 7 Series nrog ib tug kuj "me" ntim (M30B28, M30B28LE thiab tag nrho cov qauv nrog kev ua tau zoo txog li 3000 cm3) yog suav hais tias yog feem ntau txais thiab haum zoo nrog loj BMW lub cev. Kev sib xyaw ua ke ntawm lub zog thiab kev nrawm yog txhawb nqa los ntawm tus nqi tsim nyog rau kev kho thiab kho. Qhov teeb meem nkaus xwb: tswj qhov kub thiab txias.
Cov motors no yog capricious rau qhov kub thiab txias hloov, yog li nws yog ib qho tseem ceeb heev uas yuav tsum tau them sai sai mus rau lub txias system. Kev siv cov tshuaj tiv thaiv tsis zoo los yog tshuaj tiv thaiv kab mob yuav ua rau tsis tsuas yog ua rau kub dhau, tab sis kuj ua rau muaj kev puas tsuaj rau lub twj tso kua mis lossis lub tog raj kheej taub hau. Los ntawm txoj kev, cov twj tso kua mis hauv cov qauv nrog lub ntim txog li 3000 cm3 tsis ruaj khov.
- Ob chav roj av thiab diesel ntawm 7 Series feem ntau tsim cov roj smudges tom qab 300000 km. Qhov no siv ntau rau cov combustion engine nrog ib tug ntim txog li 3000 cm3. Ua rau: roj lim o-ring, lub tog raj kheej taub hau gasket los yog crankshaft seals. Thiab yog tias thawj qhov teeb meem yog pheej yig los kho, ces ob qho tib si tuaj yeem raug nqi zoo nkauj.
- Cov units M30B33LE, M30B33, M30B32LAE, M30B35M, M30B35MAE thiab M30B35LE txawv los ntawm lwm yam combustion engines los ntawm lawv exorbitant roj qab los noj mov. Lub kaw lus roj yuav tsum tau kuaj xyuas ntau zaus thiab sib npaug sib npaug sib npaug. Nws yog qhov zoo dua los siv cov roj nplua nyeem kim kim, txwv tsis pub lub teeb ci ntsa iab ntawm qhov ntsuas qis hauv cov roj yuav ua rau lub tsheb thauj mus los hu.
- N74B60, N73B60, M70B50 thiab M73B54 yog cov cav nrog 12 lub tog raj kheej ua haujlwm uas yuav ua rau mob taub hau tiag tiag rau cov tswv ntawm BMW 7 Series. Txhua chav tsev muaj ob lub tshuab roj thiab ob lub tshuab tswj. 2 lub tshuab ntxiv - 2 zaug ntxiv teeb meem. Peb tuaj yeem hais tias lub cav 12-lub tog raj kheej yog ob lub cav 6-lub tog raj kheej, thiab cov nqi rau nws cov kev tu thiab kho yog sib txuam.
Muaj lwm qhov teeb meem tseem ceeb nrog rau tag nrho BMW 7 Series sab hauv combustion engine qauv: qhov tsis muaj qhov zoo thiab ruaj khov hloov pauv rau thawj qhov chaw. Cov khoom lag luam los ntawm Suav lossis Kaus Lim Kauslim yuav raug nqi ib nrab ntawm ntau npaum li cas (uas tsis yog ib txwm txhais tau tias me me) tab sis yuav kav ntev li ob peb lub hlis. Hauv qhov no, feem ntau tsis muaj kev lav phib xaub; yuav qhov hloov pauv rau lub cav German hloov mus rau hauv kev ua si ntawm roulette.
Qhov zoo tshaj plaws thiab phem tshaj cav ntawm BMW 7 Series
Nyob rau hauv ib lub tsheb qauv, muaj kev vam meej configurations thiab tsis tag nrho cov kev vam meej. Lub tswv yim no tsis tau khiav tawm ntawm BMW 7 Series, txhua tiam neeg uas tau qhia lawv qhov tsis zoo tshaj 40 xyoo ntawm kev ua haujlwm.
M60B40 tau lees paub tias yog chav tsev zoo tshaj plaws ntawm txhua tiam neeg ntawm BMW 7 Series; nws yog kev ua haujlwm tiag tiag, tsim los ntawm txhais tes ntawm German engineers. Lub yim-lub tog raj kheej cav nrog kev hloov ntawm 3900 cm3, nruab nrog ob chav turbocharging, qhia cov yam ntxwv ntawm kev kub ceev thiab kev pab lub neej ntev. Hmoov tsis zoo, kev tsim cov cav no nres ntawm 3500 thiab kev kho cov chav nyob niaj hnub no yuav raug nqi ib nrab ntawm cov nqi ntawm lub tsheb.
N57D30OL thiab N57D30TOP yog cov khoom siv hluav taws xob siv hluav taws xob sab hauv combustion, kuj pheej yig los tswj, nrog kev siv roj zoo. Paired nrog ib tug tsis siv neeg gearbox, lub cav no qhia amazing durability. Tsuas yog cov khoom uas tsis muaj zog npaum li lub cav combustion yog lub turbocharger. Yog hais tias lub turbine ua tsis tau thiab tsis tuaj yeem kho tau ib txwm, hloov nws yuav raug nqi tus tswv nyiaj zoo nkauj.
Ksk tau qhia saum toj no, kaum ob lub tog raj kheej yog suav tias yog qhov teeb meem tshaj plaws, tshwj xeeb tshaj yog N74B60 thiab N73B60. Cov teeb meem tsis tu ncua nrog cov roj siv hluav taws xob, kev kho mob kim heev, kev siv roj ntau dhau - qhov no tsuas yog cov npe luv luv ntawm qhov ua haujlwm tsis zoo uas tseem tos cov tswv ntawm BMW 7 Series nrog kaum ob lub tog raj kheej sab hauv combustion xyaw. Ib qho teeb meem tshwj xeeb yog kev siv roj ntau, thiab kev txhim kho cov cuab yeej siv roj ntawm German tsuas yog ntxiv rau koj qhov mob taub hau.
Kev xaiv ib txwm nyob nrog tus neeg siv, tab sis koj tuaj yeem nkag siab tam sim ntawd tias BMW 7 Series tsis yog rau txhua tus.
