BMW M54B22 injini

Injini ya BMW M54B22 ndi gawo la mndandanda wa M54. Idapangidwa ndi Munich Plant. Sales chitsanzo choyamba cha galimoto ndi mphamvu wagawo anayamba mu 2001 ndipo anapitiriza mpaka 2006. Chotchinga cha injini ndi aluminiyumu, monganso mutu. Kenako manjawo amapangidwa ndi chitsulo chonyezimira.

Injini ya M54 ili ndi miyeso yoyenera yokonza. Ma pistoni asanu ndi limodzi amayendetsa crankshaft ya injini yamafuta. Kugwiritsa ntchito unyolo wanthawi yayitali kwawonjezera kudalirika kwa gawo lamagetsi. Ma camshafts, omwe ali awiri mu injini, ali pamwamba. Dongosolo la Double vanOS limathandiza kuonetsetsa kuti ma valve akuyenda bwino.

Dongosolo la Double VANOS limathandiza ma camshafts kusinthasintha molingana ndi ma sprockets, poganizira zamtundu wamagetsi. Kugwiritsa ntchito mitundu yosiyanasiyana ya utsi wa pulasitiki kunatsimikizira kukhala chisankho choyenera. Chifukwa cha kukhalapo kwake, ma cylinders amadzazidwa ndi mpweya wochuluka kwambiri, womwe umawonjezera mphamvu. Poyerekeza ndi injini ya kuloŵedwa m'malo M52, zobwezedwa ali ndi kutalika lalifupi, koma awiri okulirapo.

Madalaivala sayenera kudandaula za kusintha valavu chilolezo, chifukwa injini ali okonzeka ndi hydraulic lifters. Dongosolo logawa gasi limapereka magwiridwe antchito ndi magawo osiyanasiyana otsegulira ndi kutseka kwa mavavu olowera komanso otulutsa.

zitsanzo zosiyanasiyana anali okonzeka ndi injini ndi kusamuka kwa 2.2, 2,5 ndi 3 malita. Kuti apereke ma voliyumu osiyanasiyana ogwirira ntchito, okonzawo adasintha m'mimba mwake ndi kugunda kwa pistoni. Magawo osiyanasiyana otsegulira ndi kutseka ndi zotsatira za njira yogawa gasi.

Kudalirika, zofooka, kusakhazikika

Galimoto imasiyanitsidwa ndi kudalirika kwake. Zimagwira ntchito bwino komanso popanda phokoso. The throttle imayendetsedwa pakompyuta. Ngakhale ndi makina akuthwa pa accelerator pedal, singano ya tachometer imakwera nthawi yomweyo.

Magalimoto amtundu wa BMW 5 Series ali ndi dongosolo lotalikirapo pokhudzana ndi olamulira. Wopangayo adatha kuwongolera kukhazikika kwa injini, komanso kuchepetsa kuchuluka kwa mawaya pogwiritsa ntchito zida zoyatsira zosiyana pa kandulo iliyonse ya platinamu. Nthawi imayendetsedwa ndi unyolo, womwe umakhala ndi zotsatira zabwino pa kudalirika kwa mphamvu yamagetsi. Pali ma counterweights 12 pa crankshaft. Thandizo limapangidwa ndi mayendedwe akuluakulu - 7 ma PC.

Zovuta zomwe zingachitike:

• Kuphika mwachangu mphete za pistoni;
• Kuchulukitsa kwamafuta mpaka 1 lita pa 100 km, pambuyo pa 200 zikwi kuthamanga;
• Kugwa kuchokera pachitsulo chachitsulo kuchokera ku valve yozungulira;
• Kusakhazikika kwa injini;
• Kulephera kwa sensor ya camshaft.

Kuchepetsa kukangana kwa ma silinda ndi ma pistoni kumatheka pogwiritsa ntchito mapangidwe opepuka komanso siketi yafupikitsa yazinthu zomaliza zogwirira ntchito. The accelerator mafuta ntchito ngati malo mpope ndi pressure regulator. injini imalemera 170 kg.

Eni ambiri amawona injiniyo ngati yopambana komanso yodalirika kwambiri. Koma panthawi imodzimodziyo, mphamvu yamagetsi idzapitirira 5-10 ngati mumagwiritsa ntchito mafuta apamwamba ndi mafuta. Kuphatikiza apo, ndikofunikira kuchita ntchito zosamalira munthawi yake. Pakachitika zovuta, ndikofunikira kulumikizana ndi malo othandizira munthawi yake kapena kudzikonza nokha.

Mavuto ndi ma hydraulic compensators

Ena eni magalimoto ndi BMW M54B22 injini kuyaka mkati akukumana ndi maonekedwe a kugogoda fluttering pansi pa nyumba. Ndikosavuta kusokoneza ndi phokoso la ma hydraulic lifters. M'malo mwake, zikuwoneka ngati chotsatira cha pini yachitsulo yomwe ikugwa kuchokera pa valve yozungulira. Cholakwacho chimakonzedwa mosavuta. Kuti muchotse phokosolo, muyenera kubwezeretsanso piniyo.

Pankhani ya insufficiently yolondola ntchito compensators hydraulic, mphamvu ya masilindala amachepetsa. Izi zimachitika chifukwa cha kusakwanira kwa valve kutseka injini ikazizira. Chifukwa cha kukonza kusagwira bwino ntchito kwa silinda ndi gawo lowongolera, kuperekera mafuta kumalo ake ogwirira ntchito kumasokonekera. Izi zimabweretsa kusakhazikika kwa injini yoyaka mkati. Kukongoletsedwa ndikusintha zonyamula ma hydraulic.

Kutaya mafuta ndi antifreeze

Vuto lina lodziwika bwino la injini ndikuwonongeka kwa ma valve osiyanitsa ndi mpweya wabwino. Chifukwa cha kuwonongeka kumeneku, injini imayamba kuwononga mafuta ambiri.

M'nyengo yozizira, vutoli limakula kwambiri, chifukwa pali kuwonjezeka kwa mpweya wa crankcase ndipo, chifukwa chake, kufinya zisindikizo ndi kutuluka kwa mafuta. Choyamba, chivundikiro cha valavu ya silinda yamutu chimafinyidwa.

Mpweya, womwe umalowa mkati mwa cholumikizira pakati pa zobweza zambiri ndi mutu, umasokoneza magwiridwe antchito a injini. Pankhaniyi, chotsatira chabwino ndikuchotsa gasket, ndipo choyipa kwambiri, m'malo mwake chong'ambika.

Pakhoza kukhala kutayikira kuchokera ku thermostat. Zimapangidwa ndi pulasitiki, choncho pakapita nthawi zimayamba kutaya mawonekedwe ake ndikutulutsa antifreeze. Madalaivala nthawi zambiri amakumana ndi mawonekedwe a ming'alu pachivundikiro cha pulasitiki cha mota.

Kusakhazikika kwa gawo lamagetsi kungakhale chifukwa cha kulephera kwa sensa imodzi kapena zingapo za camshaft. Vuto si wamba, koma nthawi zina eni BMW kutembenukira ku malo utumiki ndi zizindikiro za vuto la sensa.

Kutentha kwa injini

Ngati galimoto ikuwotcha pakugwira ntchito, ndiye kuti mutu wa aluminiyumu sungathe kupeŵeka. Popanda ming'alu, akupera amatha kuperekedwa. Ntchitoyi idzabwezeretsa ndege. Kutentha kwambiri kumabweretsanso kuvula ulusi mu chipika chomwe mutu wa silinda umamangiriridwa. Kuti mubwezeretse, ndikofunikira kuchita ulusi ndi mainchesi akulu.

Kutentha kwambiri kungakhale chifukwa cha chopondera chosweka. Atapanga chisankho mokomera chitsulo chosungunulira, madalaivala amateteza galimotoyo kuti isatenthedwe ngati pulasitiki mnzake wathyoka.

Zikuoneka kuti injini ndi zovuta ndi sachedwa kuwonongeka, koma si. Mavuto omwe angachitike m'galimoto iliyonse adalembedwa pamwambapa. Ndipo sizowona kuti mwiniwake aliyense adzakhala nazo. Nthawi yasonyeza kuti M54 ndi injini yodalirika ndipo ikhoza kukonzedwa.

Kutsegula

Injini yaing'ono kwambiri ya M54, yomwe ili ndi malita 2,2, imatha kusintha ndikuwonjezera kuchuluka kwa ntchito. Kuti muzindikire lingaliro, muyenera kugula crankshaft yatsopano ndi ndodo zolumikizira kuchokera ku injini ya M54B30. Panthawi imodzimodziyo, ma pistoni akale amasungidwa, gasket yaikulu ya silinda yamutu ndi gawo lolamulira la M54B25 limasinthidwa. Chifukwa cha zochita zoterezi, mphamvu yamagetsi idzawonjezeka ndi 20 hp.

250 hp malire Mutha kudutsidwa pogwiritsa ntchito zida za ESS compressor. Koma mtengo wa ikukonzekera kotero kuti adzakhala opindulitsa kwambiri kugula M54B30 injini yatsopano kapena galimoto. Monga injini ya M50B25, imatha kukwezedwa kuti isamuke malita 2,6. Kuti mukwaniritse ntchitoyi, muyenera kugula crankshaft ya M52B28 ndi majekeseni komanso kuchuluka kwa M50B25. Zotsatira zake, galimotoyo idzakhala ndi mphamvu yofikira 200 hp.
