Engines BMW M62B44, M62TUB44
Txheem
Nyob rau hauv 1996, ib tug tshiab series ntawm BMW M62 xyaw tau tshwm sim nyob rau hauv lub ntiaj teb no kev ua lag luam.
Ib qho ntawm feem nthuav cav yog lub series - yim-lub tog raj kheej BMW M62B44 nrog ib tug ntim ntawm 4,4 liters. Ib lub cav ua ntej M60B40 tau ua ib hom qauv rau ICE no.
Cav piav qhia
Yog tias koj saib, tom qab ntawd hauv M62B44 koj tuaj yeem pom ntau qhov sib txawv ntawm M60B40. Nov yog qee qhov ntawm lawv:
- Lub tog raj kheej thaiv tau hloov pauv raws li cov kab tshiab ntawm cov thooj voos kheej kheej no.
- Muaj ib tug tshiab crankshaft ua los ntawm steel, ntev-stroke, nrog rau counterweights.
- Cov yam ntxwv ntawm cov camshafts tau hloov pauv (theem 236/228, nqa 9/9 millimeters).
- Lub sij hawm sib txuas ob kab tau hloov nrog ib kab ib zaug, nrog cov peev txheej ntawm ob puas txhiab kilometers.
- Throttle li qub tau hloov kho thiab cov khoom noj khoom haus tau hloov pauv.
Tab sis ntau yam tseem tsis tau hloov. Yog li, piv txwv li, M62B44 lub tog raj kheej taub hau yuav luag zoo tib yam rau lub taub hau uas nyob ntawm M60 series units. Tib yam siv rau kev sib txuas rods thiab li qub (ceeb toom: txoj kab uas hla ntawm cov khoom siv li qub ntawm no yog 35 millimeters, thiab cov qhov tso pa tawm yog 30,5 millimeters).
Ntxiv rau qhov pib ntawm lub cav no, muaj ib qho kev hloov kho tshiab - nws tau txais lub npe M62TUB44 (muaj lwm tus sau M62B44TU, tab sis qhov no yog qhov zoo ib yam) thiab tshwm sim hauv khw hauv 1998. Thaum lub sij hawm hloov tshiab (hloov tshiab), VANOS gas faib theem tswj system tau ntxiv rau lub cav. Ua tsaug rau qhov system no, lub cav ua haujlwm zoo hauv txhua hom thiab muaj kev sib tw zoo. Tsis tas li ntawd, ua tsaug rau VANOS, kev ua tau zoo yog nce thiab lub tog raj kheej filling yog txhim kho. Tsis tas li ntawd nyob rau hauv cov kev hloov kho tshiab version muaj ib qho hluav taws xob throttle thiab ib qho khoom noj khoom haus nrog tsawg dua. Bosch DME M7,2 system tau muab los ua kev tswj hwm rau qhov hloov tshiab.
Tsis tas li ntawd, nyob rau hauv TU xyaw, lub tog raj kheej liners pib ua tsis yog los ntawm nikasil li ua ntej (nikasil yog ib tug tshwj xeeb npib tsib xee-silicon alloy tsim los ntawm German manufacturers), tab sis los ntawm alusil (ib tug alloy muaj li ntawm 78% txhuas thiab 12% silicon).
Ib tug tshiab series ntawm BMW engine nrog ib tug V8 configuration - lub N62 series - nkag mus rau hauv lub lag luam nyob rau hauv 2001. Thaum kawg, tom qab ob peb xyoos, qhov no ua rau kev txiav tawm ntawm cov khoom zoo sib xws, tab sis tseem tsis tshua muaj qib siab ntawm cov tsev neeg M.

Lub cav naj npawb M62B44 thiab M62TUB44 tuaj yeem pom nyob rau hauv lub cev qhuav dej, nruab nrab ntawm lub tog raj kheej taub hau, hauv qab lub throttle. Txhawm rau pom nws, koj yuav tsum tshem tawm cov yas tiv thaiv npog thiab saib ntawm lub platform me me hauv nruab nrab ntawm qhov thaiv. Txhawm rau kom yooj yim rau kev tshawb nrhiav, nws raug nquahu kom siv lub teeb nyem. Yog tias koj nrhiav tsis tau tus lej ntawm thawj zaug sim, koj yuav tsum tshem tawm, ntxiv rau lub casing, thiab lub throttle. Koj tuaj yeem pom cov lej ntawm cov cav no hauv "qhov". Chav tsev no yuav luag tsis qias neeg ntawm no, txawm tias plua plav tuaj yeem ua rau nws zoo.
Cov tsheb yog M62B44 thiab M62TUB44
Lub cav BMW M62B44 tau teeb tsa rau:
- BMW E39 540i;
- БМВ 540i Kev Tiv Thaiv E39;
- BMW E38 740i/740iL;
- BMW E31 840 TSI.
Ib qho kev hloov kho tshiab ntawm BMW M62TUB44 tau siv rau:
- BMW E39 540i;
- BMW E38 740i/740iL;
- BMW E53 X5 4.4i;
- Morgan Aero 8;
- Land Rover Range Rover III.
Nws yog tsim nyog sau cia tias Morgan Aero 8 tsis yog lub tsheb kis las tsim los ntawm BMW, tab sis los ntawm lub tuam txhab Askiv Morgan. Thiab Land Rover Range Rover III kuj yog lub tsheb ua British.
Qhov tsis zoo thiab cov teeb meem tshwm sim ntawm BMW M62B44 cav
Muaj ob peb qhov teeb meem tiag tiag uas cov neeg tsav tsheb uas tsav tsheb nrog cov lus piav qhia yuav tsum tau hais txog:
- Lub cav M62 pib khob. Yog vim li cas rau qhov no tej zaum yuav yog, piv txwv li, ib tug stretched sij hawm saw los yog tensioner bar.
- Ntawm M62, lub valve npog gasket pib xau, nrog rau cov dej txias txias. Koj tuaj yeem daws qhov teeb meem no nyob rau hauv txoj kev pom tseeb - hloov lub reservoir, intake manifold gaskets thiab twj tso kua mis.
- Lub zog M62B44 pib ua haujlwm tsis sib xws thiab ruaj khov (qhov no tseem hu ua "floating speed"). Qhov tshwm sim ntawm qhov teeb meem no yog txuam nrog, raws li txoj cai, nrog rau ingress ntawm huab cua mus rau hauv lub intake manifold. Nws kuj tuaj yeem tshwm sim los ntawm qhov tsis xws luag hauv KVKG, throttle sensors, cua ntws ntsuas. Ib txwm muaj kev sib kis ntawm cov throttle li qub tuaj yeem ua rau tsis ruaj khov.
Nyob rau sab saum toj ntawm qhov ntawd, tom qab kwv yees li 250 txhiab mais, kev siv roj nce ntxiv ntawm M62 (los daws qhov teeb meem no, nws raug nquahu kom hloov lub valve qia ntsaws ruaj ruaj). Tsis tas li ntawd, tom qab 250 txhiab kilometers, lub cav mounts yuav raug tso tseg.
M62B44 thiab M62TUB44 lub zog hluav taws xob yog tsim los cuam tshuam nrog cov roj zoo - nws yog qhov zoo tshaj plaws los siv cov npe pom zoo los ntawm cov chaw tsim khoom nws tus kheej. Cov no yog cov roj 0W-30, 5W-30, 0W-40 thiab 5W-40. Tab sis cov roj cim 10W-60 yuav tsum tau siv nrog kev saib xyuas, tshwj xeeb tshaj yog nyob rau lub caij ntuj no - nws yog tuab, thiab nyob rau lub caij txias ntawm lub xyoo yuav muaj teeb meem pib lub cav. Feem ntau, cov kws tshaj lij tsis qhia kom txuag cov dej ua haujlwm yog tias lub tsheb muaj lub cav M62. Nws kuj tsis tsim nyog tsis saib xyuas raws sijhawm thiab kev saib xyuas.
Kev ntseeg tau thiab kev ruaj ntseg ntawm BMW M62B44
M62B44 lub cev muaj zog (ob qho tib si hauv paus thiab TU version) featuring qib siab ntawm kev ntseeg siab thiab kev nyab xeeb. Nyob rau hauv tas li ntawd, nws muaj zoo heev traction ntawm tsawg revs, thiab nyob rau hauv lwm yam kev khiav hauj lwm hom. Cov peev txheej ntawm lub cev muaj zog, nrog kev saib xyuas kom raug, tuaj yeem kov yeej qhov ntsuas ntawm 500 txhiab kilometers.
Feem ntau, lub cev muaj zog yog tsim rau ob qho tib si hauv zos thiab kev kho loj. Txawm li cas los xij, nws muaj tag nrho cov teeb meem ntawm lub teeb yuag aluminium engine coated nrog nikasil thiab alusil. Hauv ib puag ncig kev tshaj lij, qee tus txawm hu cov motors "tso pov tseg". Interestingly, alusil cylinder blocks yog suav tias yog ntau tshaj li cov nikasil - uas yog, TU-variation muaj tej yam zoo nyob rau hauv no nam.
Thaum muas lub tsheb siv nrog lub cav no, nws raug nquahu kom kuaj xyuas lub cav tam sim ntawd thiab tshem tawm tag nrho cov teeb meem pom. Xws li kev nqis peev yuav ua rau koj xav tias muaj kev ntseeg siab dua tom qab lub log.
kev xaiv kho
Cov neeg uas xav kom lub zog ntawm BMW M62TUB44 yuav tsum ua ntej ntawm tag nrho cov nruab ib tug intake manifold nrog wider raws nyob rau hauv lub cav no (piv txwv li, los ntawm lub hauv paus version).
Nws tseem yog ib qho tsim nyog rau nruab cov camshafts zoo dua ntawm no (piv txwv li, nrog cov ntsuas ntawm 258/258), kev ua kis las tso tawm manifold thiab hloov kho. Yog li ntawd, koj tuaj yeem tau txais txog 340 horsepower - qhov no txaus rau ob lub nroog thiab txoj kev loj. Tsis muaj qhov taw tes hauv kev tsuas yog chipping M62B44 lossis M62TUB44 xyaw yam tsis muaj kev ntsuas ntxiv.
Yog tias xav tau lub zog rau 400 horsepower, tom qab ntawd cov khoom siv compressor yuav tsum tau yuav thiab ntsia. Muaj ntau yam khoom siv muaj nyob rau hauv cov khw muag khoom online thiab offline uas haum rau tus qauv BMW M62 piston sib dhos, tab sis tus nqi tsis yog qis tshaj. Ntxiv nrog rau cov khoom siv compressor, lub twj tso kua mis Bosch 044 kuj tseem yuav tsum tau yuav. Yog li ntawd, yog tias qhov siab ntawm 0,5 bar mus txog, daim duab ntawm 400 horsepower yuav dhau mus.
Lub cia rau tuning, raws li cov kws txawj, yog hais txog 500 horsepower. Hauv lwm lo lus, lub cav no yog qhov zoo rau kev sim nrog lub zog.
Raws li rau turbocharging, nyob rau hauv cov ntaub ntawv no nws tsis yog heev profitable los ntawm ib tug economic taw tes ntawm view. Nws yuav yooj yim dua rau tus neeg tsav tsheb hloov mus rau lwm lub tsheb ntawm tib hom - mus rau BMW M5.
