mafotokozedwe

Mechanically, BMW B38 ndi ofanana mayunitsi B48 ndi B37. Analandira ma valve 4 pa silinda imodzi, Twin-scroll supercharger, teknoloji ya TwinPower ndi dongosolo la jekeseni wolunjika wa petulo. Palinso Valvetronic system (yowongolera nthawi ya valavu), shaft yolumikizira, chotsitsa chotsitsa kugwedezeka. Injiniyi yapeza bwino kwambiri zachilengedwe pochepetsa kuchuluka kwa zinthu zovulaza zomwe zimatulutsidwa mumlengalenga mpaka mulingo wa EU6.

Pali zosintha zosiyanasiyana zamainjini okhala ndi masilinda atatu. BMW imapereka mitundu yokhala ndi voliyumu ya silinda iliyonse mpaka ma kiyubiki metres 3, mphamvu kuchokera ku 0.5 mpaka 75 hp, torque kuchokera 230 mpaka 150 Nm. Ndipo ngakhale zopangira mphamvu za 320-silinda zikuyembekezeka kukhala zofooka, 3 hp. mphamvu ndi 230 Nm wa makokedwe ndi kuposa zokwanira osati zolimbitsa mzinda galimoto. Nthawi yomweyo, mayunitsi ndi ndalama zambiri pafupifupi 320-10% poyerekeza tingachipeze powerenga injini 15 yamphamvu.

Mwa njira, mu 2014, injini B38 analandira malo 2 mu gulu "Injini Chaka" pakati mayunitsi ndi buku la malita 1.4-1.8. Malo oyamba adapita ku injini ya BMW / PSA.

Ndime

Pali zosintha zosiyanasiyana za injini iyi:

1. B38A12U0 - yoyikidwa pamagalimoto a MINI. Pali mitundu iwiri ya injini za B2A38U12: ndi mphamvu ya 0 ndi 75 hp. Kusiyanitsa kwa mphamvu kumatheka poonjezera chiwerengero cha psinjika mpaka 102. Ma injiniwo adalandira voliyumu ya malita 11, ndipo pafupifupi mafuta awo anali 1.2 l / 5 km.
2. B38B15A - anaika pa BMW 116i F20 / 116i F21. Mphamvu ndi 109 hp, torque - 180 Nm. Pa avareji, injini amadya malita 4.7-5.2 pa 100 Km. M'mimba mwake ya silinda yawonjezeka poyerekeza ndi B38A12U0 - kuchokera 78 mpaka 82 mm.
3. B38A15M0 ndi chimodzi mwazofala zosinthidwa. Itha kupezeka pazitsanzo za nkhawa: 1-series, 2-series, 3-series, X1, Mini. Chipangizochi chili ndi mphamvu ya 136 hp. ndi makokedwe 220 Nm okonzeka ndi crankshaft ndi sitiroko pisitoni 94.6 mm ndi masilindala ndi awiri a 82 mm.
4. B38K15T0 ndi TwinPower Turbo sports hybrid injini, yomwe imapangidwa pamaziko a zosintha za B38 - imaphatikizapo makhalidwe abwino amitundu yonse ndipo imayikidwa mu BMW i

kusinthidwa otsiriza kumafuna chidwi kwambiri, popeza injini B38K15T0, ndi mphamvu mkulu (231 HP) ndi makokedwe (320 NM), amadya malita 2.1 okha pa 100 Km, amene ndi mbiri pakati pa zomera mphamvu mafuta. Pa nthawi yomweyi, voliyumu yake imakhala yofanana - 1.5 malita.

Zithunzi za B38K15T0

Kodi mainjiniya a BMW adakwanitsa bwanji kuchita bwino chonchi? Poyerekeza ndi ma B38 okhazikika, kusinthidwa kwa B38K15T0 kunalandira zosintha zina:

1. Pampu ya antifreeze imayikidwa kutsogolo. Kwa izi, crankcase idayenera kusinthidwa mwapadera. Izi zinali zofunikira pakukonzekera kaphatikizidwe ka mpweya wotengera mpweya ndi jenereta.
2. Pampu yamafuta opepuka.
3. Zingwe zazikulu zolumikizira ndodo.
4. Lamba woyendetsa wowonjezera (kuyambira nthiti 6 mpaka 8).
5. Mutu wapadera wa silinda unapangidwa mu kuponyera mphamvu yokoka, zomwe zinapangitsa kuti ziwonjezere mphamvu zake.
6. Kuchulukitsa kwa shaft ya valve yotulutsa mpaka 6 mm. Njira yothetsera vutoli idapangitsa kuti zitheke kuthetsa kugwedezeka komwe kumachitika chifukwa cha kukakamizidwa ndi supercharger.
7. Anasintha lamba galimoto ndi tensioners. Galimoto imayambitsidwa ndi jenereta yamagetsi apamwamba, palibe magiya oyambira.
8. Chifukwa cha kuwonjezeka kwa mphamvu mu lamba pagalimoto, kunali koyenera kukhazikitsa zolimbitsa zoyendetsa shaft.
9. Stabilizer yokhazikika idasunthidwa kutsogolo kwa crankcase.
10. Madzi utakhazikika gulugufe vavu.
11. Nyumba ya turbine ya Compressor yophatikizidwa muzosiyanasiyana.
12. Supercharger kuzirala kudzera m'nyumba zonyamula.

Zosintha zonsezi zawonjezera mphamvu ya injini ndi mawonekedwe ake.

zolakwa

Malingana ndi ndemanga za eni ake pamabwalo oyenerera, ndizosatheka kutchula mavuto aakulu. Madalaivala ambiri amakhutitsidwa ndi mainjiniwa ndi magalimoto otengera iwo onse. Chokhacho ndi chakuti kugwiritsa ntchito mafuta mumzindawu sikusiyana kwambiri ndi mayunitsi a 4-cylinder. Mu mzinda, injini "amadya" malita 10-12, pa khwalala - 6.5-7 (izi sizikugwira ntchito kwa injini wosakanizidwa pa i8). Palibe mafuta omwe adawonedwa, panalibe ma dips a rpm kapena mavuto ena. Zoona, ma motors awa ndi aang'ono ndipo mu zaka 5-10, mwinamwake zofooka zawo zidzawonekera kwambiri chifukwa cha kutaya kwa gwero.

Mgwirizano wa ICE

Ma injini a B38B15 ndi atsopano, ndipo chifukwa chakuti oyamba adapangidwa mu 2013, amakhalabe atsopano kuyambira pakati pa 2018. Ndizosatheka kutulutsa zida zamagalimoto awa muzaka 5, chifukwa chake ma mota a B38B15 akulimbikitsidwa kugula.

Kutengera ndi momwe chipangizocho chilili, ma mileage ndi zolumikizira, zida zamagetsi izi zitha kugulidwa pafupifupi ma ruble 200 zikwi.

Posankha injini ya mgwirizano, choyamba muyenera kuganizira chaka chomwe chimatulutsidwa ndikuyesera kutenga injini yoyaka moto momwe mungathere. Apo ayi, gwero lalikulu silingatsimikizidwe.

Pomaliza

Ma motors a banja la B38 ndi zida zamakono zamakono zomwe zachitika posachedwa kwambiri paukadaulo waku Germany. Ndi voliyumu yaying'ono, amapereka mphamvu zambiri zamahatchi, amakhala ndi torque yayikulu.
