Kufotokozera kwa injini za BMW M50B20 ndi M50B20TU

Mndandanda wa M50 umaphatikizapo injini zokhala ndi mphamvu ya 2, 2.5, 3 ndi 3.2 malita. Odziwika kwambiri anali injini za M50B20 ndi voliyumu yeniyeni ya malita 1.91. Injini idapangidwa m'malo mwa injini yakale ya M20B20. Kusintha kwake kwakukulu kuposa omwe adatsogolera ndi chipika chokhala ndi masilinda 6, aliwonse omwe ali ndi ma valve 4. Mutu wa silinda udalandiranso ma camshafts awiri ndi ma hydraulic lifters, chifukwa chomwe kufunikira kosinthira ma valve pambuyo pa 10-20 km kutha.

BMW M50B20 ndi M50B20TU amagwiritsa ntchito camshafts ndi gawo la 240/228, mavavu olowera ndi mainchesi 33 mm, ma valve otulutsa - 27 mm. Imakhalanso ndi mapulasitiki opangira pulasitiki kuti achepetse kulemera kwa injini, ndipo mapangidwe ake apangidwa bwino poyerekeza ndi oyambirira a banja la M20.

Komanso M50B20, m'malo lamba pagalimoto, odalirika unyolo pagalimoto, moyo utumiki umene ndi makilomita 250 zikwi. Izi zikutanthauza kuti eni ake akhoza kuiwala za vuto la lamba wosweka ndi kupindika kotsatira kwa ma valve. Komanso mu injini yoyaka mkati, njira yoyatsira pakompyuta idagwiritsidwa ntchito, m'malo mwa wogawa, zida zoyatsira, ma pistoni atsopano, ndi ndodo zolumikizira kuwala zidayikidwa.

Mu 1992, injini ya M50B20 inasinthidwa ndi dongosolo lapadera la Vanos. Anatchedwa M50B20TU. Dongosololi limapereka kuwongolera kwamphamvu kwa ma camshafts, ndiko kuti, kusintha kwa nthawi ya valve. Chifukwa cha ukadaulo uwu, mapindikidwe a ma torque amasintha, kukwera kwa injini kumakhalanso kokhazikika pamagawo onse a ntchito yake. Ndiko kuti, pa injini M50B20TU pa liwiro otsika ndi mkulu, makokedwe adzakhala apamwamba kuposa M50B20, amene adzaonetsetsa mphamvu (mathamangitsidwe) wa galimoto ndi, chiphunzitso, kupulumutsa mafuta. Kaya liwiro kasinthasintha wa crankshaft, injini amakhala wokonda ndalama ndi chilengedwe, ndipo chofunika kwambiri - wamphamvu kwambiri.

Pali machitidwe angapo a VANOS: Mono ndi Double. M50B20 imagwiritsa ntchito njira yodziwika bwino ya mono-VANOS, yomwe imasintha magawo otsegulira ma valve olowera. Ndipotu, luso limeneli ndi analogi wa VTEC odziwika bwino ndi i-VTEC ku HONDA (wopanga aliyense ali ndi dzina lake luso limeneli).

Mwaukadaulo, kugwiritsa ntchito VANOS pa M50B20TU kunapangitsa kuti zitheke kusuntha torque yayikulu kupita ku liwiro lotsika - mpaka 4200 rpm (4900 rpm mu M50B20 popanda dongosolo la VANOS).

Choncho, 2-lita injini ya banja M50 analandira zosintha 2:

1. Kusintha koyambira popanda Vanos system yokhala ndi chiŵerengero cha 10.5, 150 hp. ndi makokedwe 190 Nm pa 4700 rpm.
2. Ndi Vanos system, ma camshafts atsopano. Apa, psinjika chiŵerengero anakwezedwa 11, mphamvu ndi chimodzimodzi - 150 HP. pa 4900 rpm; makokedwe - 190 Nm pa 4200 rpm.

Ngati musankha pakati pa njira ziwiri, ndiye kuti yachiwiri ndi yabwino. Chifukwa cha kukhazikika kwa torque pa liwiro lotsika, lapakati komanso lalitali, injiniyo imathamanga kwambiri pazachuma komanso yokhazikika, ndipo galimotoyo imakhala yamphamvu komanso yomvera poyendetsa gasi.

Kutsegula

Injini zokhala ndi mphamvu ya malita 2 zilibe mphamvu yayikulu, kotero eni ake a M50B20 nthawi zambiri amayesa kuwongolera. Pali njira zowonjezera mphamvu zamahatchi popanda kutaya gwero.

Njira yosavuta ndikugula mota ya M50B25 yosinthira. Ndiwoyenera kwathunthu m'malo mwake pamagalimoto okhala ndi M50B20 ndi 2 hp amphamvu kwambiri kuposa mtundu wa 42-lita. Kuphatikiza apo, pali njira zosinthira M50B25 kuti muwonjezere mphamvu.

Palinso njira zosinthira injini ya "M50B20" "yachibadwidwe". Chophweka ndi kuonjezera voliyumu yake kuchokera 2 mpaka 2.6 malita. Kuti muchite izi, muyenera kugula pisitoni ku M50TUB20, masensa oyenda mpweya ndi crankshaft - kuchokera M52B28; ndodo zolumikizira zimakhalabe "zachibadwidwe". Mudzafunikanso kutenga zigawo zingapo kuchokera ku B50B25: valve yothamanga, ECU yokonzedwa, yowongolera kuthamanga. Ngati zonsezi zitayikidwa bwino pa M50B20, ndiye kuti mphamvu yake idzawonjezeka kufika ku 200 hp, chiwerengero cha compression chidzakwera kufika 12. Choncho, mafuta omwe ali ndi octane apamwamba adzafunika, kotero kuti mafuta a AI-98 okha ayenera kuwonjezeredwa. , apo ayi kuphulika kudzachitika ndi kutsika mphamvu. Poika gasket wandiweyani pamutu wa silinda, mutha kuyendetsa pamafuta a AI-95 popanda mavuto.

Ngati injini ndi Vanos dongosolo, ndiye nozzles ayenera kusankha M50B25, ndodo kulumikiza M52B28.

Zosintha zomwe zapangidwa zidzakweza mphamvu ya ma silinda - zotsatira zake zidzakhala pafupifupi M50B28 yodzaza, koma kuti mutsegule mphamvu zake zonse, m'pofunika kukhazikitsa valavu yamagetsi ndikulowetsamo zambiri kuchokera ku M50B25, masewera amtundu wofanana. , kulitsa ndi kusintha njira zolowera ndi zotuluka za mutu wa silinda (porting). Zosintha izi zidzawonjezera mphamvu mpaka zotheka - galimoto yotereyi idzapitirira mphamvu ya M50B25.

Pazogulitsa pazinthu zoyenera pali zida za stroker zomwe zimakulolani kuti mupeze voliyumu ya 3 malita. Kuti achite izi, ayenera kunyong'onyeka 84 mm, pistoni ndi mphete, crankshaft ndi ndodo kulumikiza m54B30 ayenera kuikidwa. Silinda yokhayo imadulidwa ndi 1 mm. Mutu wa silinda ndi zingwe zimatengedwa kuchokera ku M50B25, 250 cc jekeseni amayikidwa, mndandanda wathunthu wa unyolo wanthawi. Padzakhala zigawo zochepa zomwe zatsala kuchokera ku M50B20 yayikulu, tsopano idzakhala M50B30 Stroker yokhala ndi voliyumu ya 3 malita.

Mutha kupeza mphamvu zambiri popanda kugwiritsa ntchito supercharger mwa kukhazikitsa ma camshaft a Schrick 264/256, nozzles kuchokera ku S50B32, 6-throttle intake. Izi zikuthandizani kuti muchotse za 260-270 hp ku injini.

Zida za Turbo

Njira yosavuta yopangira turbocharge 2L M50 ndikukwanira turbo kit ya Garrett GT30 yokhala ndi masensa a MAP, ma turbo manifold, ma probe a lambda a Broadband, ma jakisoni apamwamba a 440cc, kulowetsa kwathunthu komanso kutulutsa mpweya. Mufunikanso fimuweya yapadera kuti zigawo zonsezi zigwire ntchito bwino. Pazotulutsa, mphamvu idzawonjezeka kufika 300 hp, ndipo izi zili pagulu la piston.

Mutha kukhazikitsanso ma injectors a 550 cc ndi turbo ya Garett GT35, m'malo mwa pistoni za fakitale ndi CP Pistons, kukhazikitsa ndodo zatsopano zolumikizira za APR ndi mabawuti. Izi zidzachotsa 400+ hp.

Mavuto

Ndipo ngakhale injini ya M50B20 ili ndi gwero lalitali, ili ndi mavuto:

1. Kutentha kwambiri. Ndilo khalidwe la pafupifupi injini zonse zoyaka mkati zomwe zili ndi index ya M. Chipangizocho ndi chovuta kupirira, kotero kupitirira kutentha kwa ntchito (madigiri 90) kuyenera kuchititsa dalaivala nkhawa. Muyenera kuyang'ana thermostat, mpope, antifreeze. Mwina kutentha kumayamba chifukwa cha kukhalapo kwa matumba a mpweya mu dongosolo lozizira.
2. Mavuto obwera chifukwa cha ma nozzles osweka, ma coil poyatsira, ma spark plugs.
3. Vanos system. Nthawi zambiri, eni injini ndi teknoloji iyi amadandaula za kugwedeza mutu wa silinda, kuthamanga kwa kusambira, ndi kuchepa kwa mphamvu. Muyenera kugula zida zokonzera Vanos M50.
4. Zosintha zosambira. Chilichonse ndi chokhazikika pano: valavu yosweka yopanda ntchito kapena sensa ya throttle position. Nthawi zambiri amathetsedwa ndi kuyeretsa mota ndi damper palokha.
5. Kutaya mafuta. Chifukwa cha kuwonongeka kwachilengedwe kwa injini ya M50B20 imatha "kudya" 1 lita imodzi pa 1000 km. Kuwongolera kumatha kwakanthawi kapena osathetsa vutoli konse, chifukwa chake muyenera kuwonjezera mafuta. Komanso, chivundikiro cha valve chikhoza kutayikira apa, ngakhale mafuta amatha kutuluka kudzera mu dipstick.
6. Tanki yokulitsa pa antifreeze imatha kusweka pakapita nthawi - chozizirirapo chimachoka pakung'ambika.

Mavutowa amapezeka pama motors ogwiritsidwa ntchito, koma izi ndizabwinobwino. Ngakhale zonse, injini za M50 ndizodalirika kwambiri. Awa ndi injini zodziwika bwino, zomwe mwa injini zonse zoyatsira mkati zomwe zimapangidwa ndi nkhawa yaku Germany ndi zina mwazabwino komanso zopambana kwambiri. Iwo alibe mawerengedwe olakwika, ndipo mavuto omwe amabwera amakhala okhudzana ndi kuvala kapena ntchito yosayenera.
