BMW N62B36, N62B40 cav
Txheem
Tom qab ntawd, tom qab M62B35, 8-lub tog raj kheej piston fais fab chav tsev ntawm lub teeb-alloy tsim, N62B36 los ntawm BMW Plant Dingolfing, tau mus rau hauv ntau lawm, uas hloov nws lub npe nrov predecessor. N62B44 yog lub hauv paus rau kev tsim lub cav.
N62B 36
Hauv BC N62B36 ntsia: crankshaft nrog lub piston stroke ntawm 81.2 hli; cylinders nrog ib txoj kab uas hla ntawm 84 mm thiab tshiab txuas rods.
Lub taub hau lub tog raj kheej zoo ib yam li N62B44, tshwj tsis yog rau txoj kab uas hla ntawm cov khoom siv, uas tau dhau los ua me - 32 hli. Exhaust li qub tseem zoo li qub - 29 mm.
Tsis tas li ntawd hauv N62B36, Valvetronic thiab Ob Chav VANOS tau tshwm sim. Lub hwj chim chav tsev yog tswj los ntawm Bosch DME ME version nrog firmware 9.2.
Lub cav tau nruab rau hauv BMW 35i kom txog rau thaum German automaker pib hloov nws nrog ib tug redesigned N2005B62 nyob rau hauv 40.

N62B 40
Nyob rau tib lub sijhawm nrog lub peev xwm loj N62B48, BMW Plant Dingolfing tau tsim nws cov khoom sib xws, N62B40, uas hloov lub cav N62B36. Lub hauv paus rau kev txhim kho ntawm qhov kev teeb tsa no yog qhov tseeb ntawm N62B48, hauv BC ntawm cov crankshaft nrog 84.1 hli piston stroke thiab lub tog raj kheej nrog txoj kab uas hla ntawm 87 hli tau teeb tsa.
N62B40 lub tog raj kheej lub taub hau tau txais kev txhim kho combustion chambers thiab li qub tau hloov kho rau kev tso tawm tshiab (nrog rau cov yeeb nkab txuas ntxiv). Cov khoom siv rau kev tsim lub taub hau yog ib qho txhuas alloy nrog silicon - silumin. Tsis tas li ntawd rau N62B40, ib qho tshiab ob-theem noj nrog DISA system yuav raug teeb tsa.
Lub cav tswj qhov system yog Bosch ECU version DME ME nrog firmware 9.2.2. Lub cev muaj zog no tau siv rau ntawm BMW 40i qauv.
Txij li thaum 2008, tag nrho tsev neeg ntawm N62 powertrains tau maj mam hloov los ntawm ib tug tshiab series ntawm N63 turbocharged units.

Qhov zoo thiab cov teeb meem ntawm N62B36 thiab N62B40
Yav tas los
- Dual-VANOS/Bi-VANOS
- valvetronic
- kev pab
Daim ntawv
- Maslozhor
- Floating kiv puag ncig
- Roj xau
Ntawm qhov tsis zoo tseem ceeb ntawm N62B36 thiab N62B40 lub cav, kev siv roj ntau dua tau sau tseg. Qhov no feem ntau tshwm sim tom qab kev khiav ntawm 100 txhiab km. thiab yog vim li cas rau txhua yam yog lub valve qia ntsaws ruaj ruaj. Tom qab txog ib puas txhiab mais, cov roj scraper rings thaum kawg poob.
Floating revolutions, raws li txoj cai, tshwm sim vim tsis ua hauj lwm ntawm lub ignition coil. Koj tseem tuaj yeem tshawb xyuas Valvetronic gas tis system, muaj huab cua to, lub ntsuas dej ntws.
Qhov tshwm sim ntawm cov roj xau, raws li txoj cai, tshwm sim vim lub crankshaft foob los yog lub tshuab hluav taws xob vaj tsev gasket. Tsis tas li ntawd, cov cell ntawm catalysts uas vau dhau lub sij hawm xaus rau hauv lub tog raj kheej, ua rau cov qhab nia. Qhov kev daws teeb meem zoo tshaj plaws hauv qhov no yuav yog hloov cov catalysts nrog cov nplaim taws.
Feem ntau, yog li ntawd cov peev txheej ntawm N62B36 thiab N62B40 lub cav yog ntev npaum li qhov ua tau, thiab muaj ob peb teeb meem nrog lawv raws li qhov ua tau, nws yog qhov zoo dua kom tsis txhob txuag cov roj cav thiab roj, thiab tseem ua kom muaj kev saib xyuas tsis tu ncua.
Kev hloov kho N62B36 thiab N62B40
Txoj hauv kev tsim nyog tshaj plaws los kho N62B36 yog txhawm rau nti lub kaw lus. Koj tseem yuav xav tau: lub tshuab ua si, lub lim dej tsis zoo thiab qhov chaw zoo ntawm ECU nws tus kheej. Tag nrho cov no yuav tso cai rau koj mus txog 300 hp. thiab muab lub cav zoo dynamics. Nws tsis muaj txiaj ntsig ua lwm yam, nws zoo dua tsuas yog hloov lub tsheb.
Kev kho kom zoo ntawm N62B40 rau cov nyiaj txaus yuav tsis ua haujlwm, thiab ntawm no koj yuav tsum xaiv: chipping lossis kim turbocharger. Flashing chav tswj, ua ke nrog xoom tsis kam lim thiab txhim kho kev ua kis las, yuav tuaj yeem muab 330-340 hp. thiab ib qho kev xav ntawm txhoj puab heev cav ua haujlwm.

Hauv cov ntsiab lus, nws muaj kev nyab xeeb los hais tias N62 lub zog hluav taws xob, koom nrog New Generation engine series, tau txais kev hloov pauv zoo rau M62. Piv nrog rau nws cov thawj, N62 lub cev muaj zog tau hloov pauv tseem ceeb, ob qho tib si mechanically thiab digitally. Ua tsaug rau txhua qhov kev tsim kho tshiab, cov kws ua haujlwm tau tswj hwm kom muaj zog thiab txhim kho lub zog, nrog rau txo cov roj noj thiab cov pa phem rau hauv qhov chaw.
Ntawm qhov tod tes, kev txhim kho thiab kev tsim kho tshiab tau ua rau kev ua haujlwm ntawm cov tiam tshiab ntawm lub zog ntawm lub zog ntau dua, tab sis ntawm qhov tod tes, tag nrho cov no tau ua rau lawv nyuaj heev, uas tau dhau los ua "capricious". Qhov no siv tsis tsawg rau N62B36 thiab N62B40 xyaw. Ib qho ntawm qhov teeb meem tshaj plaws hauv N62 yog cov lus hais txog Ob Chav Vanos. Tsis tas li ntawd ib qho tsis muaj zog yog cov neeg kho tshuab ntawm Valvetronic system.
Ntawm kev sib tw International Powertrain hauv xyoo 2002, N62B36 tau txais cov npe hauv qab no: "Lub Cav Zoo Tshaj Plaws", "Lub Cav Zoo Tshaj Plaws ntawm Lub Xyoo", thiab tseem yog tus yeej hauv qeb: "Zoo tshaj 4-litre Cav".
