BMW B38A15M0, B38B15, B38K15T0 izinjini

I-B38 iyinjini engu-3-cylinder eyingqayizivele, emele isisombululo sesimanje kakhulu (phakathi no-2018) esivela ku-BMW ukukhathazeka. Lezi zinjini zisebenza kahle kakhulu futhi zikhiqiza futhi, empeleni, zingenisa inkathi entsha yezinjini ezivuthayo zangaphakathi zikaphethiloli. Izici zenjini zifaka ukusebenza kahle ngokwedlulele, amandla aphezulu, i-torque, nokubumbana. Injini ngokwayo ihlala ilula naphezu kokusebenza kwayo okuphezulu.

Incazelo

Ngomshini, i-BMW B38 ifana neyunithi ye-B48 ne-B37. Bathole ama-valve angu-4 isilinda, i-Twin-scroll supercharger, ubuchwepheshe be-TwinPower kanye nesistimu yomjovo kaphethiloli oqondile. Kukhona nesistimu ye-Valvetronic (yokulawula isikhathi se-valve), i-balance shaft, kanye ne-vibration damper. Le njini izuze ubungane obuphezulu bemvelo, yehlisa umthamo wezinto eziyingozi ezikhishelwa emkhathini ziye ezingeni le-EU6.

Kukhona ukuguqulwa okuhlukile kwezinjini ezi-3-cylinder. I-BMW inikeza izinguqulo ezinomthamo we-cylinder ngayinye kuze kufike ku-0.5 cubic metres, amandla asuka ku-75 kuya ku-230 hp, i-torque esuka ku-150 kuya ku-320 Nm. Futhi nakuba ama-powerplants angama-3-cylinder bekulindeleke ukuthi abe buthakathaka, ama-230 hp. amandla kanye ne-torque engu-320 Nm kungaphezu kokwanele hhayi kuphela ekushayeleni kwedolobha okulingene. Ngesikhathi esifanayo, amayunithi ngokwesilinganiso 10-15% ukonga ngaphezulu uma kuqhathaniswa zakudala 4-cylinder izinjini.

Ngendlela, ngo-2014, injini ye-B38 yathola indawo yesibili esigabeni esithi "Injini Yonyaka" phakathi kwamayunithi anevolumu ye-2-1.4 amalitha. Indawo yokuqala ibe yinjini ye-BMW/PSA.

Izindima

Kukhona ukuguqulwa okuhlukile kwale motor:

1. I-B38A12U0 - efakwe ezimotweni ze-MINI. Kukhona 2 izinguqulo B38A12U0 izinjini: ngamandla 75 futhi 102 hp. Umehluko emandleni ufinyelelwa ngokwandisa isilinganiso sokucindezela sibe ngu-11. Izinjini zithole umthamo we-cylinder 1.2 amalitha, futhi ukusetshenziswa kwawo kwamafutha kwakungu-5 l/100 km.
2. I-B38B15A – ifakwe ku-BMW 116i F20/116i F21. Amandla angu-109 hp, i-torque engu-180 Nm. Ngokwesilinganiso, injini idla amalitha angu-4.7-5.2 ngebanga elingu-100 km. Ububanzi besilinda bunyusiwe uma kuqhathaniswa ne-B38A12U0 - kusuka ku-78 kuya ku-82 mm.
3. I-B38A15M0 ingenye yezinguquko ezivame kakhulu. Ingatholakala kumamodeli okukhathazeka: 1-series, 2-series, 3-series, X1, Mini. Le yunithi ikhiqiza i-136 hp. kanye ne-torque engu-220 Nm ifakwe i-crankshaft ene-piston stroke engu-94.6 mm namasilinda anobubanzi obungu-82 mm.
4. I-B38K15T0 iyinjini eyi-hybrid yezemidlalo ye-TwinPower Turbo, eyakhiwe ngesisekelo sezinguquko ezikhona ze-B38 - ihlanganisa izimfanelo ezinhle kakhulu zazo zonke izinguqulo futhi ifakwe ku-BMW i

Ukuguqulwa kwakamuva kudinga ukunakwa okwengeziwe, njengoba injini ye-B38K15T0, enamandla amakhulu (231 hp) ne-torque (320 Nm), idla amalitha angu-2.1 kuphela nge-100 km, okuyirekhodi phakathi kwezitshalo zamandla kaphethiloli. Nokho, umthamo wayo uhlala efanayo - 1.5 amalitha.

Imifanekiso ye-B38K15T0

Onjiniyela bakwa-BMW bakwazi kanjani ukuzuza ukusebenza okuphezulu kangaka? Uma kuqhathaniswa ne-B38 evamile, ukuguqulwa kwe-B38K15T0 kuthole izinguquko ezithile:

1. Iphampu ye-antifreeze ifakwe ngaphambili. Ukuze wenze lokhu, i-crankcase kwakudingeka ishintshwe ngokukhethekile. Lokhu kwakudingeka ukuze kube nokuhlelwa okuhlangene kwesistimu yokungenisa umoya kanye nejeneretha.
2. Iphampu kawoyela engasindi.
3. Ubukhulu obunyukile bokuxhuma izinduku.
4. Ibhande lokushayela elinwetshiwe (kusuka kwezimbambo ezi-6 kuye kweziyi-8).
5. Ikhanda le-cylinder elikhethekile lakhiqizwa kusetshenziswa i-gravity casting, okwenza kube nokwenzeka ukwandisa ukuminyana kwayo.
6. Ububanzi obukhulisiwe be-valve yokukhipha i-shaft kuya ku-6 mm. Lesi sixazululo siqede ukudlidliza okuvela ngenxa yokucindezela kweshaja enkulu.
7. I-modified belt drive kanye nama-tensioners. Injini iqalwa yi-generator ephezulu kagesi, awekho amagiya okuqalisa ajwayelekile.
8. Ngenxa yamandla akhulayo ekushayeleni kwebhande, kwakudingeka kufakwe ama-shaft bearings aqinisiwe.
9. I-stabilizer bar ihanjiswe ngaphambi kwe-crankcase.
10. I-valve ye-throttle yamanzi epholile.
11. Izindlu ze-compressor turbine ezihlanganiswe ku-multifold.
12. Ukupholisa ishaja enkulu ngesihlalo sokuthwala.

Zonke lezi zinguquko ziye zathuthukisa ukusebenza kahle kwenjini nokusebenza kwayo.

amaphutha

Ngokusekelwe ekubuyekezweni okuvela kubanikazi bezinkundla ezifanele, akunakwenzeka ukuhlonza izinkinga ezinkulu. Iningi labashayeli ligculisekile ngalezi zinjini nezimoto ezisuselwe kuzona ngokujwayelekile. Into kuphela ukuthi ukusetshenziswa kukaphethiloli edolobheni akufani kakhulu namayunithi angama-4-cylinder. Edolobheni injini idla amalitha angu-10-12, emgwaqeni omkhulu - 6.5-7 (lokhu akusebenzi enjini ye-hybrid ku-i8). Akukho ukusetshenziswa kwamafutha okwaphawulwa, kwakungekho ukwehla kwejubane noma ezinye izinkinga. Yiqiniso, lezi motors zincane futhi eminyakeni engu-5-10, mhlawumbe, ukushiyeka kwabo kuyoba sobala kakhulu ngenxa yokulahlekelwa impilo yesevisi.

Inkontileka ICE

Izinjini ze-B38B15 zintsha, futhi uma kubhekwa ukuthi ezokuqala zazo zakhiqizwa ngo-2013, zihlala zizintsha kusukela maphakathi no-2018. Cishe akunakwenzeka ukufinyelela impilo yesevisi yalawa ma-motor eminyakeni emi-5, ngakho-ke izinjini zenkontileka B38B15 zinconywa ukuthi zithengwe.

Ngokuya ngesimo seyunithi, imayela nokunamathiselwe, lezi zitshalo zamandla zingathengwa ngokwesilinganiso sama-ruble ayizinkulungwane ezingama-200.

Lapho ukhetha injini yenkontileka, kufanele uqale ucabangele unyaka wokwakhiwa kwayo bese uzama ukukhetha injini yakamuva yomlilo yangaphakathi. Uma kungenjalo, insiza enkulu ayikwazi ukuqinisekiswa.

isiphetho

Izimoto zomndeni we-B38 ziyizitshalo zamandla ezithuthuke kakhulu ezisebenzisa impumelelo yakamuva yezobuchwepheshe yokukhathazeka kweJalimane. Ngomthamo omncane, bakhiqiza amandla amaningi amahhashi futhi bane-torque ephezulu.
