BMW M52B28 injini

injini poyamba anaika mu March 1995 pa BMW 3-mndandanda, ndi E36 index.

Pambuyo pake, gawo lamagetsi linayikidwa pazithunzi zina za BMW: Z3, 3-mndandanda E46 ndi 3-mndandanda E38. Mapeto a kupanga injini zimenezi kunayamba mu 2001. Pazonse, injini za 1 zidayikidwa m'magalimoto a BMW.

Zithunzi za M52B28

1. Injini yoyamba idalembedwa M52B28 ndipo idapangidwa pakati pa 1995 ndi 2000. Ndi base unit. Kuponderezana ndi 10.2, mphamvu ndi 193 hp. pamtengo wa 280 Nm pa 3950 rpm.
2. M52TUB28 ndiye membala wachiwiri wamitundu iyi ya BMW. Kusiyana kwakukulu ndi kukhalapo kwa kachitidwe ka Double-VANOS pakudya komanso kutulutsa mpweya. Mtengo wa psinjika chiŵerengero ndi mphamvu zasintha, ndipo anakwana 10.2 ndi 193 HP. motero, pa 5500 rpm. Mtengo wa torque ndi 280 Nm pa 3500 rpm.

Makhalidwe aukadaulo ndi mawonekedwe a injini

Injini ili ndi geometry square. Miyeso yonse ndi 84 ndi 84 mm. The awiri yamphamvu ndi chimodzimodzi m'badwo wapita wa injini M52 mzere. Kutalika kwa pisitoni ndi 31,82 mm. Mutu wa silinda umabwereka ku injini ya M50B25TU. Chitsanzo cha nozzles ntchito injini M52V28 ndi 250cc. Kumayambiriro kwa 1998, kusinthidwa kwatsopano kwa injiniyi kunalowa mukupanga, komwe kunali M52TUB28.

Kusiyanitsa kwake ndiko kugwiritsa ntchito manja achitsulo, ndipo mmalo mwa vanos system, makina awiri a vanos adayikidwamo. Camshaft magawo: kutalika 244/228 mm, kutalika 9 mm. Ili ndi ma pistoni ndi ndodo zolumikizira. DISA variable geometry exhaust manifold yasinthidwanso.

Kwa nthawi yoyamba pamzere wa M52, makina opangira magetsi ndi ozizira amayikidwa. Magalimoto onse omwe adayikidwa ma motors awa adalandira index ya i28. mu 2000, injini ya M54B30 inalowa kupanga, yomwe ili m'malo mwa M52B28, yomwe inatha mu 2001.

Injini iyi ili ndi vanos imodzi yokhala ndi zokutira nikasil.

Mosiyana ndi injini ya M52B25 injini, chipika chomwe chimapangidwa ndi chitsulo chosungunula, mu injini ya M52B28, kulemera kwa flywheel, komanso pulley yakutsogolo, yomwe imapangidwira kuti ichepetse kugwedezeka kwa torsional, ndizochepa kwambiri. Izi zimathandiza kuti ntchito zamphamvu za galimoto lonse bwino. Kukula kwa ma valve ndi 6 mm, mu kapangidwe kake pali kasupe wamtundu umodzi wa cone. Silinda ya injini ya M52V28 imapangidwa ndi aluminium. Mapangidwe olimbikitsa chipika amapangidwa ndi ma couplers apadera ndi mabulaketi. Kapangidwe kameneka kalibe kukhazikika kwa monolithic, izi zimakuthandizani kuti muzitha kubweza zolakwika zosiyanasiyana pamene mota yatenthedwa.

Maboti omangirira ma goli mu chipika cha injini ya aluminium M52B28 ndiatali kuposa mabawuti omwe amagwiritsidwa ntchito mu midadada ya silinda yachitsulo. Mafuta nozzles injini, voliyumu ndi malita 2.8, ndi malo olondola kuposa kuloŵedwa m'malo ake.

Nsonga zawo zimalunjika pansi pa pistoni pamalo aliwonse a crankshaft. Dziwani kuti zovundikira kutsogolo ndi kumbuyo crankshaft pa gaskets mtundu "Metal phukusi". Komanso zisindikizo za mafuta a crankshaft, popanda kugwiritsa ntchito akasupe achitsulo. Izi zinapangitsa kuti achepetse kuvala kwa malo opaka.

Piston dongosolo la injini M52B28 ndi apamwamba kwambiri. Poyerekeza ndi injini yaying'ono, crankshaft ya injini yoyaka yamkati ya B28 ndiyotalika kwambiri, chifukwa chake ma pistoni amagwiritsidwa ntchito ndi kutalika kocheperako. Pansi pa pistoni pali mawonekedwe athyathyathya.

Madera ovuta a injini za M52B28

1. Chinthu choyamba kuzindikira ndikutentha kwambiri. Injini kuchokera mndandanda wa M52, komanso makhazikitsidwe a injini ndi index ya M50, yomwe idapangidwa kale pang'ono, nthawi zambiri imatenthedwa. Pofuna kuthetsa vutoli, ndikofunikira kuyeretsa radiator nthawi ndi nthawi, komanso kutulutsa mpweya kuchokera ku dongosolo lozizira, fufuzani mpope, thermostat ndi kapu ya radiator.
2. Vuto lachiwiri lodziwika bwino ndilowotcha mafuta. Zikuwoneka chifukwa choti mphete za pistoni zimatha kuvala kwambiri. Pakawonongeka makoma a masilindala, ndikofunikira kuchita ndondomeko ya manja. Ngati ali osasunthika, ndiye kuti mutha kungodutsa m'malo mwa mphete za pistoni. M'pofunikanso kufufuza mmene valavu, amene ali ndi udindo mpweya wa crankcase mpweya.
3. Vuto la kusokonekera kumachitika pamene zonyamula ma hydraulic zaphimbidwa. Izi zimabweretsa kuti magwiridwe antchito a silinda amatsika ndipo gawo lowongolera pakompyuta limazimitsa. Njira yothetsera vutoli ndi kugula zida zatsopano zonyamula ma hydraulic.
4. Nyali yamafuta imayatsa pa chida. Chifukwa cha izi chikhoza kukhala kapu yamafuta kapena pampu yamafuta.
5. Ndi kuthamanga pambuyo 150 zikwi Km. pakhoza kukhala mavuto ndi vanos. Zizindikiro za kutuluka kwake pakuyima ndizo: maonekedwe a kugwedezeka, kutsika kwa mphamvu ndi liwiro la kusambira. Kuthetsa vutoli, muyenera kugula zida kukonza injini M52.

Palinso mavuto ndi kulephera kwa crankshaft ndi camshaft udindo masensa. Pochotsa mutu wa silinda, zingakhale zovuta kulumikiza kugwirizana. Thermostat si yabwino kwambiri ndipo nthawi zambiri imayamba kutsika.

Mafuta a injini oyenera kugwiritsa ntchito injini iyi: 0W-30, 0W-40, 5W-30, 5W-40. Pafupifupi moyo wa injini, ndi ntchito mosamala, ndi ntchito mafuta apamwamba ndi mafuta akhoza kukhala oposa 500 zikwi Km.

Kuyika injini yokonza BMW M52B28

Imodzi mwa njira zosavuta ikukonzekera ndi kugula wokhometsa wabwino, amene anaikidwa pa M50B52 ICE. Pambuyo pake, perekani injini ndi mpweya wozizira komanso camshafts kuchokera ku SD52B32, ndiyeno yesetsani kukonza injini. Pambuyo pakuchita izi, pafupifupi, pafupifupi 240-250 ndiyamphamvu amapezeka. Mphamvu imeneyi idzakhala yokwanira kukwera bwino mumzinda ndi kupitirira. Ubwino wa njirayi ndi mtengo wotsika.

Njira ina ndikuwonjezera kuchuluka kwa ma silinda mpaka 3 malita. Kuti muchite izi, muyenera kugula crankshaft ku M54B30. Pambuyo pake, pisitoni yokhazikika imachepetsedwa ndi 1.6 mm. Zinthu zina zonse zimakhalabe zosakhudzidwa. Komanso, kuti muwongolere mawonekedwe amagetsi, tikulimbikitsidwa kugula ndikuyika kuchuluka kwa M50B25.

Njira yosavuta ndiyo kukhazikitsa Garrerr GT35 turbocharger. Kuyika kwake kumachitika pa pisitoni system M52B28. Mtengo wa mphamvu ukhoza kufika 400 ndiyamphamvu. Kuti muchite izi, muyenera kusintha Megasquirt, pamphamvu ya 0,7 bar.

Kudalirika kwa unsembe wa injini sikuchepa, ngakhale kuwonjezeka kwakukulu kwa kuchuluka kwa mphamvu. Kupanikizika kwamtengo komwe pisitoni yokhazikika M52B28 imatha kupirira ndi bar 1. Izi zikusonyeza kuti ngati sapota injini mpaka 450-500 HP, muyenera kugula pisitoni limagwirira, ndi psinjika chiŵerengero cha 8.5.

Mafani a Compressor amatha kugula zida zodziwika bwino za ESS zotengera Lysholm. Ndi zoikamo izi, injini M52B28 akufotokozera 300 HP. ndi ndondomeko ya piston.
