BMW M62B44, M62TUB44 injini

Mu 1996 pa msika padziko lonse panali mndandanda watsopano wa BMW M62 injini.

Imodzi mwa injini chidwi kwambiri ndi mndandanda - eyiti yamphamvu BMW M62B44 ndi buku la malita 4,4. Injini yoyambirira ya M60B40 idakhala ngati mtundu wamtunduwu wa injini yoyaka mkati.

Kufotokozera kwa injini

Ngati muyang'ana, ndiye kuti mu M62B44 mungapeze zosiyana kwambiri ndi M60B40. Nazi zochepa chabe mwa izo:

• Chida cha silinda chasintha malinga ndi ma diameter atsopano a masilindalawa.
• Panali crankshaft yatsopano yopangidwa ndi zitsulo, zazitali zazitali, zokhala ndi masikelo asanu ndi limodzi.
• Magawo a camshafts asintha (gawo 236/228, kwezani 9/9 millimeters).
• Unyolo wa nthawi ya mizere iwiri unasinthidwa ndi mzere umodzi, wokhala ndi gwero la makilomita pafupifupi mazana awiri.
• Ma valve a Throttle asinthidwa ndipo kuchuluka kwa kudya kwasinthidwa.

Koma zinthu zambiri sizinasinthe. Mwachitsanzo, mitu yamphamvu ya M62B44 imakhala yofanana ndi mitu yomwe inali pamagulu a mndandanda wa M60. Zomwezo zimagwiranso ntchito polumikiza ndodo ndi ma valve (chidziwitso: m'mimba mwake ma valve olowera apa ndi 35 millimeters, ndi ma valve otulutsa mpweya ndi 30,5 millimeters).

Kuphatikiza pa mtundu woyambira wa injini iyi, pali mtundu womwe wasinthidwa luso - adalandira dzina la M62TUB44 (pali mtundu wina wa kalembedwe M62B44TU, koma izi ndizofanana) ndipo zidawonekera pamsika mu 1998. Panthawi yosintha (zosintha), makina owongolera gasi a VANOS adawonjezeredwa ku injini. Chifukwa cha makinawa, injini imagwira ntchito bwino m'njira zonse ndipo imakhala yabwino. Kuphatikiza apo, chifukwa cha VANOS, kuchita bwino kumawonjezeka ndipo kudzaza kwa silinda kumakhala bwino. Komanso mu mtundu wosinthidwa mwaukadaulo munali chiwongolero chamagetsi komanso njira zambiri zolowera zomwe zili ndi mayendedwe ochepa. Dongosolo la Bosch DME M7,2 linaperekedwa ngati njira yowongolera yosinthidwa.

Kuphatikiza apo, mu injini za TU, zomangira za silinda zinayamba kupangidwa osati kuchokera ku nikasil monga kale (nikasil ndi aloyi yapadera ya nickel-silicon yopangidwa ndi opanga ku Germany), koma kuchokera ku alusil (aloyi yomwe ili ndi pafupifupi 78% aluminium ndi 12% silicon).

Mndandanda watsopano wa injini za BMW ndi kasinthidwe ka V8 - mndandanda wa N62 - unalowa msika mu 2001. Pamapeto pake, patatha zaka zingapo, izi zidapangitsa kuti kutha kwa zida zofananira, koma zocheperako kuchokera ku banja la M.

Nambala ya injini M62B44 ndi M62TUB44 imapezeka mu kugwa, pakati pa mitu ya silinda, pansi pa throttle. Kuti muwone, muyenera kuchotsa chivundikiro cha pulasitiki chotetezera ndikuyang'ana pa nsanja yaying'ono pakatikati pa chipikacho. Pofuna kufufuza, tikulimbikitsidwa kugwiritsa ntchito tochi. Ngati simunapeze nambala pakuyesera koyamba, ndiye kuti muyenera kuchotsa, kuwonjezera pa casing, komanso phokoso. Mutha kuwonanso manambala a injini awa mu "dzenje". Chipindachi sichikhala chodetsedwa pano, ngakhale fumbi limatha kuwunjikana pamenepo.

Ndi magalimoto ati M62B44 ndi M62TUB44

Injini ya BMW M62B44 idayikidwa pa:

• BMW E39 540i;
• БМВ 540i Chitetezo E39;
• BMW E38 740i/740iL;
• BMW E31 840Ci.

Mtundu wosinthidwa wa BMW M62TUB44 unagwiritsidwa ntchito pa:

• BMW E39 540i;
• BMW E38 740i/740iL;
• BMW E53 X5 4.4i;
• Morgan Aero 8;
• Land Rover Range Rover III.

Dziwani kuti Morgan Aero 8 si masewera galimoto opangidwa ndi BMW, koma ndi kampani English Morgan. Ndipo Land Rover Range Rover III ndi galimoto yopangidwa ku Britain.

Kuipa ndi mavuto wamba injini BMW M62B44

Pali zovuta zingapo zomwe oyendetsa magalimoto omwe amayendetsa magalimoto ndi injini zomwe zafotokozedwa ayenera kuwunikira:

• Injini ya M62 imayamba kugunda. Chifukwa cha izi chikhoza kukhala, mwachitsanzo, unyolo wotambasulira nthawi kapena tensioner bar.
• Pa M62, chivundikiro cha valve chimayamba kutsika, komanso chosungira chozizira. Mutha kuthana ndi vutoli mwanjira yodziwikiratu - sinthani thanki, ma gaskets ochulukirapo komanso mpope.
• Mphamvu ya M62B44 imayamba kugwira ntchito mosagwirizana komanso mokhazikika (izi zimatchedwanso "liwiro loyandama"). Kupezeka kwa vutoli kumagwirizanitsidwa, monga lamulo, ndi kulowetsedwa kwa mpweya muzowonjezereka. Zitha kuyambitsidwanso ndi zolakwika mu KVKG, masensa a throttle, mita otaya mpweya. Kuipitsidwa kwanthawi zonse kwa ma throttle valves kungayambitsenso kuthamanga kosakhazikika.

Pamwamba pake, patatha pafupifupi makilomita 250, mafuta a M62 amawonjezeka (kuthetsa vutoli, ndi bwino kusintha zisindikizo za valve). Komanso, pambuyo 250 zikwi makilomita, injini mounts akhoza kusiyidwa.

Magawo amphamvu a M62B44 ndi M62TUB44 amapangidwa kuti azilumikizana ndi mafuta apamwamba kwambiri - ndi bwino kugwiritsa ntchito mitundu yomwe ikulimbikitsidwa ndi wopanga yekha. Awa ndi mafuta 0W-30, 5W-30, 0W-40 ndi 5W-40. Koma mafuta olembedwa 10W-60 ayenera kugwiritsidwa ntchito mosamala, makamaka m'nyengo yozizira - ndi wandiweyani, ndipo m'miyezi yozizira ya chaka pangakhale mavuto kuyambitsa injini. Ambiri, akatswiri samalangiza kupulumutsa pa madzi ntchito ngati galimoto ndi injini M62. Sikoyeneranso kunyalanyaza kukonza ndi chisamaliro chanthawi yake.

Kudalirika ndi kusakhazikika kwa BMW M62B44

M62B44 mota (yonse yoyambira ndi TU mtundu) yokhala ndi kudalirika komanso chitetezo chambiri. Kuphatikiza pa izi, imakhala ndi ma traction abwino kwambiri pama revs otsika, komanso m'njira zina zogwirira ntchito. Gwero la galimoto iyi, ndi kukonza bwino, akhoza ngakhale kugonjetsa chizindikiro cha makilomita zikwi 500.

Kawirikawiri, galimotoyo ndi yoyenera kukonzanso kwanuko komanso kwakukulu. Komabe, ili ndi mavuto onse a injini zopepuka za aluminiyamu zokutidwa ndi nikasil ndi alusil. M'malo ogwirira ntchito, ena amatcha ma motors ngati "otayidwa". Chochititsa chidwi, midadada ya alusil cylinder imatengedwa kuti ndi yapamwamba kwambiri kuposa nikasil - ndiko kuti, kusiyana kwa TU kuli ndi ubwino wina pambali iyi.

Mukamagula galimoto yogwiritsidwa ntchito ndi injini iyi, tikulimbikitsidwa kuti muzindikire injiniyo nthawi yomweyo ndikuchotsa zolakwika zonse zomwe zapezeka. Ndalama zotere zidzakuthandizani kuti mukhale olimba mtima kumbuyo kwa gudumu.

ikukonzekera options

Amene akufuna kuwonjezera mphamvu ya BMW M62TUB44 ayenera choyamba kukhazikitsa zobweza zambiri ndi njira zambiri mu injini (mwachitsanzo, kuchokera Baibulo zofunika).

M'pofunikanso kukhazikitsa bwino camshafts pano (mwachitsanzo, ndi zizindikiro za 258/258), masewera utsi wambirimbiri ndi kusintha. Chifukwa chake, mutha kupeza mphamvu zokwana 340 - izi ndizokwanira kwa mzinda ndi msewu waukulu. Palibe chifukwa chongodula injini za M62B44 kapena M62TUB44 popanda miyeso yowonjezera.

Ngati mphamvu imafunika 400 ndiyamphamvu, ndiye kuti zida za kompresa ziyenera kugulidwa ndikuyika. Pali zida zingapo zomwe zimapezeka m'masitolo apaintaneti komanso osapezeka pa intaneti zomwe zimagwirizana ndi gulu la piston la BMW M62, koma mitengo yake si yotsika kwambiri. Kuphatikiza pa makina a compressor, pampu ya Bosch 044 iyeneranso kugulidwa. Zotsatira zake, ngati kupanikizika kwa 0,5 bar kukufika, chiwerengero cha 400 horsepower chidzapitirira.

Malo osungiramo, malinga ndi akatswiri, ndi pafupifupi 500 ndiyamphamvu. Mwanjira ina, injini iyi ndiyabwino kuyesa mphamvu.

Ponena za turbocharging, pakadali pano sizopindulitsa kwambiri pazachuma. Zidzakhala zosavuta kuti dalaivala asamukire ku galimoto ina ya mtundu womwewo - ku BMW M5.
