hōʻikeʻano
Mechanically, like ka BMW B38 me ka B48 a me B37. Ua loaʻa iā lākou he 4 kiwi no kēlā me kēia cylinder, Twin-scroll supercharger, ʻenehana TwinPower a me ka ʻōnaehana hoʻokele kino. Aia kekahi ʻōnaehana Valvetronic (no ka hoʻomalu ʻana i ka manawa o ka valve), kahi kumu kaulike, kahi damper no ka haʻalulu ʻana. Ua loaʻa i kēia ʻenekini ke aloha kaiapuni kiʻekiʻe ma ka hōʻemi ʻana i ka nui o nā mea ʻino i hoʻokuʻu ʻia i ka lewa i ka pae o ka maʻamau EU6.
Aia nā hoʻololi like ʻole o nā ʻenekini me 3 cylinders. Hāʻawi ʻo BMW i nā mana me ka nui o kēlā me kēia cylinder a hiki i 0.5 cubic mika, mana mai 75 a 230 hp, torque mai 150 a 320 Nm. A ʻoiai ua manaʻo ʻia e nāwaliwali nā mana 3-cylinder, 230 hp. ʻO ka mana a me ka 320 Nm o ka torque ʻoi aku ka nui ʻaʻole wale no ka hoʻokele kūlanakauhale maʻalahi. I ka manawa like, ʻoi aku ka maikaʻi o nā ʻāpana ma ka awelika e 10-15% i hoʻohālikelike ʻia me nā mīkini 4-cylinder maʻamau.
Ma ke ala, i ka makahiki 2014, ua loa'a i ka engine B38 ka 2nd wahi ma ka wae'ano "Engine of the Year" i waena o nā hui me ka nui o 1.4-1.8 lita. Ua hele ka wahi mua i ka mīkini BMW/PSA.
Nā'Ōlelo
Aia nā hoʻololi like ʻole o kēia kaʻa:
- B38A12U0 - kau ʻia ma nā kaʻa MINI. Aia 2 mau mana o nā mīkini B38A12U0: me ka mana o 75 a me 102 hp. Loaʻa ka ʻokoʻa o ka mana ma o ka hoʻonui ʻana i ka lakene kaomi i 11. Ua loaʻa i nā ʻenekini ka nui o ka cylinder o 1.2 lita, a ʻo kā lākou awelika wahie he 5 l / 100 km.
- B38B15A - kau ʻia ma ka BMW 116i F20 / 116i F21. ʻO ka mana he 109 hp, torque - 180 Nm. Ma ka awelika, hoʻopau ka engine i 4.7-5.2 lita no 100 km. Hoʻonui ʻia ke anawaena cylinder i ka B38A12U0 - mai 78 a 82 mm.
- ʻO B38A15M0 kekahi o nā hoʻololi maʻamau. Hiki ke loaʻa iā ia ma nā hiʻohiʻona o ka hopohopo: 1-series, 2-series, 3-series, X1, Mini. He 136 hp kona mana. a me ka torque o 220 Nm ua lako me ka crankshaft me ka piston hahau o 94.6 mm a me cylinders me ka anawaena o 82 mm.
- ʻO B38K15T0 kahi ʻenekini hāmeʻa hāmeʻa TwinPower Turbo, i hoʻomohala ʻia ma ke kumu o nā hoʻololi B38 i loaʻa - ua hoʻokomo ʻia i nā ʻano maikaʻi loa o nā mana āpau a hoʻokomo ʻia i ka BMW i
Pono ka hoʻololi hope e hoʻonui i ka nānā ʻana, no ka mea, ʻo ka mīkini B38K15T0, me ka mana kiʻekiʻe (231 hp) a me ka torque (320 Nm), hoʻopau wale i 2.1 lita no 100 km, kahi moʻolelo i waena o nā mea kanu mana. I ka manawa like, e mau ana kona leo - 1.5 lita.
Nā hiʻohiʻona hoʻolālā B38K15T0
Pehea i hoʻokō ai nā ʻenekini BMW i nā pae kiʻekiʻe? Hoʻohālikelike ʻia i nā B38 maʻamau, ua loaʻa i ka hoʻololi B38K15T0 kekahi mau loli:
- Hoʻokomo ʻia ka pamu antifreeze i mua. No kēia, pono e hoʻololi kūikawā ʻia ka pahu crankcase. Pono kēia no ka hoʻonohonoho paʻa ʻana o ka ʻōnaehana hoʻokomo ea a me ka generator.
- ʻaila pauma māmā.
- Nā bearings huila anawaena nui.
- Kāʻei kaʻa lōʻihi (mai 6 a 8 iwi ʻaoʻao).
- Ua hana ʻia ke poʻo cylinder kūikawā i ka hoʻolei ʻana i ka gravity, kahi i hiki ai ke hoʻonui i kona ʻano.
- Hoʻonui ʻia ke anawaena o ka pahu pahu puka a hiki i 6 mm. ʻO kēia hoʻonā i hiki ke hoʻopau i nā haʻalulu e puka mai ana mai ke kaomi ʻana mai ka supercharger.
- Hoʻololi i ke kāʻei kāʻei a me nā mea hoʻopaʻapaʻa. Hoʻomaka ʻia ke kaʻa e ka mea hana uila kiʻekiʻe, ʻaʻohe mea hoʻomaka maʻamau.
- Ma muli o ka hoʻonui ʻana i ka mana i ka kāʻei kāʻei, pono e hoʻokomo i nā bearings shaft drive reinforced.
- Ua hoʻoneʻe ʻia ka stabilizer stabilizer i mua o ka pahu crankcase.
- ʻO ka valve lele i hoʻoluʻu wai.
- Hoʻohui ʻia ka hale turbine compressor i loko o ka manifold.
- ʻO ka hoʻolili ʻana o ka supercharger ma o ka hale bearing.
Ua hoʻomaikaʻi kēia mau hoʻololi a pau i ka pono o ka ʻenekini a me kāna mau ʻano.
hewa
Wahi a nā loiloi o nā mea nona nā ʻaha kūkā kūpono, ʻaʻole hiki ke hoʻokaʻawale i nā pilikia koʻikoʻi. Ua māʻona ka hapa nui o nā mea hoʻokele i kēia mau ʻenekini a me nā kaʻa e pili ana iā lākou ma ka laulā. ʻO ka mea wale nō ʻo ka hoʻohana ʻana i ka wahie ma ke kūlanakauhale ʻaʻole ʻokoʻa loa mai nā ʻāpana 4-cylinder. Ma ke kūlanakauhale, "ʻai" ka engine i ka 10-12 liters, ma ke alaloa - 6.5-7 (ʻaʻole pili kēia i ka engine hybrid ma ka i8). ʻAʻole ʻike ʻia ka ʻai ʻaila, ʻaʻohe rpm dips a i ʻole nā pilikia ʻē aʻe. ʻOiaʻiʻo, he ʻōpio kēia mau kaʻa a ma 5-10 mau makahiki, e ʻike ʻia paha ko lākou mau hemahema ma muli o ka nalowale ʻana o kahi kumuwaiwai.
ʻaelike ICE
He mea hou nā mīkini B38B15, a hāʻawi ʻia nā mea mua i hana ʻia ma 2013, noho hou lākou ma waena o 2018. Aneane hiki ʻole ke hoʻokuʻu i ka waiwai o kēia mau kaʻa i 5 mau makahiki, no laila ua ʻōlelo ʻia nā mīkini ʻaelike B38B15 no ke kūʻai.
Ma muli o ke kūlana o ka ʻāpana, mileage a me nā mea hoʻopili, hiki ke kūʻai ʻia kēia mau mea mana no ka awelika o 200 tausani rubles.
I ke koho ʻana i ka ʻenekini aelike, pono ʻoe e noʻonoʻo mua i ka makahiki o kona hoʻokuʻu ʻana a hoʻāʻo e lawe i kahi ʻenekini hoʻopau i loko e like me ka hiki. A i ʻole, ʻaʻole hiki ke hōʻoia i kahi kumu waiwai nui.
hopena
ʻO nā kaʻa kaʻa o ka ʻohana B38 he mau mana mana kiʻekiʻe o kēia manawa kahi i hoʻokō ʻia ai nā hana ʻenehana hou loa o ka hopohopo Kelemania. Me ka liʻiliʻi liʻiliʻi, hāʻawi lākou i ka nui o ka horsepower, he kiʻekiʻe kiʻekiʻe.
