BMW E39 - injini anaika pazithunzi 5-mndandanda galimoto

Wopanga ku Germany wasiya makasitomala ndi kusankha kwakukulu kwamagetsi opezeka pa E39. Injini zinapangidwa mu mitundu ya mafuta ndi dizilo, ndipo pakati pa gulu lalikululi pali zochitika zingapo zomwe zimawonedwa ngati zamatsenga. Timapereka zidziwitso zofunika kwambiri za injini zomwe zidayikidwa pa BMW 5 Series, komanso nkhani zamayunitsi omwe amaonedwa kuti ndi opambana kwambiri!

E39 - injini zamafuta

Pachiyambi cha kupanga galimoto anaika M52 okhala pakati asanu ndi limodzi, komanso BMW M52 V8. Mu 1998, chigamulo chinapangidwa kuti chiwonjezere luso. Izi zinaphatikizapo kukhazikitsidwa kwa machitidwe awiri a VANOS mumtundu wa M52 ndi dongosolo limodzi la VANOS mu chitsanzo cha M62. Chifukwa chake, magwiridwe antchito okhudzana ndi Nm pa low rpm adawongoleredwa.

Zosintha zotsatirazi zinachitika patapita zaka ziwiri. Mndandanda wa M52 unasinthidwa ndi BMW M54 ya 6-mizere, pamene M62 inatsalira pa zitsanzo za V8. Galimoto yatsopanoyi idalandira ndemanga zabwino kwambiri ndipo mu 10 ndi 2002 idaphatikizidwa m'magalimoto khumi apamwamba kwambiri padziko lonse lapansi malinga ndi magazini ya Ward. Pa chitsanzo cha 2003i, injini ya M54B30 inayikidwa.

E39 - injini za dizilo

Magalimoto okhala ndi injini ya dizilo anali ndi injini ya dizilo ya turbocharged yokhala ndi spark poyatsira - M51 inline 6. Mu 1998 idasinthidwa ndi M57 ndikuyika pa BMW 530d. Izi sizikutanthauza kuti sizinagwiritsidwenso ntchito - zidagwiritsidwa ntchito mu 525td ndi 525td kwa zaka zingapo.

Kusintha kotsatira kunabwera ndi kubwera kwa 1999. Kotero izo zinali ndi chitsanzo BMW 520d - M47 anayi yamphamvu turbodiesel. Ndizofunikira kudziwa kuti iyi inali mtundu wokhawo wa E39 pomwe gawo lomwe lili ndi izi zidayikidwa.

Chosankha chabwino - mayunitsi a petulo omwe adziwonetsa okha kwambiri

Magalimoto a E39 anali olemera kwambiri. Pachifukwa ichi, 2,8 lita injini ndi 190 HP, komanso akweza Baibulo 3-lita ndi 231 HP, ankaona kuti kuphatikiza mulingo woyenera kwambiri mphamvu ndi otsika mtengo ntchito. - M52 ndi M54. 

Ogwiritsa galimoto adawona kuti, mwazinthu zina, kugwiritsa ntchito mafuta amitundu yonse ya 6 ndi yofanana, kotero kugula mtundu wamagetsi a BMW E2 39-lita sikunali kwanzeru. Mtundu wokongoletsedwa bwino wa 2,5-lita unkawoneka ngati yankho labwinoko. Mitundu yamunthu payekha inali ndi mayina awa: 2,0L 520i, 2,5L 523i ndi 2,8L 528i.

Ndi mitundu yanji ya dizilo yomwe muyenera kusamala nayo?

Kwa mayunitsi a dizilo, mitundu ya M51S ndi M51TUS yokhala ndi mapampu amafuta othamanga anali chisankho chabwino. Iwo anali odalirika kwambiri. Zida zazikulu monga tcheni chanthawi ndi turbocharger zidagwira ntchito modalirika ngakhale pamtunda wa 200 km. km. Pambuyo pogonjetsa mtunda uwu, chochitika chautumiki chokwera mtengo kwambiri chinali kukonza pampu ya jekeseni.

Injini ya dizilo yamakono M57

Injini zamakono zawonekeranso mumtundu wa BMW. Amatchedwa injini ndi jekeseni mwachindunji mafuta. Madizilo a Turbo okhala ndi Common Rail system adasankhidwa 525d ndi 530d ndipo voliyumu yawo yogwira ntchito inali malita 2,5 ndi malita 3,0, motsatana. 

injini chitsanzo analandira zabwino ndipo anati kukhala ndi mlingo wapamwamba kudalirika poyerekeza ndi M51 - Dziwani kuti anali mwachindunji zokhudzana ndi ntchito mafuta apamwamba, amene chikhalidwe luso injini zimadalira. 

Makina ozizirira olakwika

Pali zovuta zingapo zomwe zimachitika mukamagwiritsa ntchito mayunitsi otchuka pagalimoto. Zolephera zambiri zinali zokhudzana ndi dongosolo lozizirira. 

Kulephera kwake kungayambitsidwe chifukwa cha kusokonekera kwa injini yothandizira fani, chotenthetsera, kapena radiator yotsekeka komanso kusintha kwamadzimadzi pagululi. Njira yothetsera vutoli ingakhale kusintha makina onse zaka 5-6 zilizonse chifukwa ndi nthawi yawo ya moyo. 

Ma coil oyatsira mwadzidzidzi ndi zamagetsi

Pamenepa, mavuto angayambe pamene wogwiritsa ntchito anasiya kugwiritsa ntchito mapulagi osakhala apachiyambi. Zida zosinthira zodziwika nthawi zambiri zimakhala zokwanira 30-40 km. km. 

Ma injini a E39 analinso ndi zinthu zambiri zamagetsi zamagetsi. Zowonongeka zitha kulumikizidwa ndi ma probe owonongeka a lambda, omwe anali ochulukirapo ngati 4 mumagalimoto okwera. Panalinso kuwonongeka kwa mita yothamanga mpweya, crankshaft position sensor ndi camshaft.

Kuwongolera ma drive omwe adayikidwa pa E39

Ubwino waukulu wa injini za E39 unali kusinthasintha kwawo pakukonza. Chimodzi mwa zosankha zodziwika bwino chinali kukonzanso luso la injini ndi makina otulutsa masewera popanda otembenuza chothandizira ndi manifolds 4-2-1, komanso kuzizira kwa mpweya ndi kukonza chip. 

Kwa zitsanzo zachilengedwe, compressor inali yankho labwino. Chimodzi mwazabwino za lingaliro ili chinali kupezeka kwakukulu kwa zida zosinthira kuchokera kwa opanga odalirika. Pambuyo poika injini ku katundu, mphamvu ya mphamvu yamagetsi ndi torque inawonjezeka. 

Kodi pali mitundu ya injini yoyenera kusamala?

Tsoka ilo, si mitundu yonse ya njinga zamoto yomwe idapambana. Izi zimagwiranso ntchito pamagawo amafuta omwe amagwiritsa ntchito zokutira za nickel-silicon cylinder.

Wosanjikiza wa nikasil wawonongedwa ndipo chipika chonsecho chiyenera kusinthidwa. gulu ili zikuphatikizapo injini anamanga mpaka September 1998, kenako BMW anaganiza m'malo Nikasil ndi wosanjikiza "Alusil", amene anaonetsetsa durability kwambiri. 

BMW E39 - injini yogwiritsidwa ntchito. Zoyenera kuyang'ana pogula?

Chifukwa chakuti zaka zambiri zapita kuyambira nthawi ya kupanga, m'pofunika kumvetsera mwapadera chikhalidwe cha galimoto yogulidwa. Poyambirira, ndikofunikira kuyang'ana ngati chipikacho chimapangidwa ndi nikasil. 

Chotsatira ndikuwunika momwe heatsink ilili komanso kuphatikizika kwa kutentha kwa fan. Thermostat ndi air conditioner radiator fan iyeneranso kukhala yabwino. Injini ya BMW E39 yomwe ili mumkhalidwe wabwino sidzatenthedwa ndipo ikupatsani chisangalalo chochuluka choyendetsa.
