Nā ʻenekini BMW N62B36, N62B40
Nā mea
A laila, ma hope o ka M62B35, ka 8-cylinder piston power unit of light-alloy construction, ka N62B36 mai BMW Plant Dingolfing, i komo i ka hana nui, kahi i pani ai i kona mea kaulana mua. ʻO ka N62B44 ke kumu no ka hana ʻana i ka ʻenekini.
N62B36
Ma BC N62B36 i hoʻokomo ʻia: crankshaft me ka piston stroke o 81.2 mm; nā cylinders me ke anawaena o 84 mm a me nā lāʻau hoʻohui hou.
ʻO ke poʻo cylinder e like me ka N62B44, koe wale ke anawaena o nā valve intake, i lilo i mea liʻiliʻi - 32 mm. Hoʻomau like nā pahu hoʻopau - 29 mm.
Ma ka N62B36, ua ʻike ʻia nā ʻōnaehana Valvetronic a me Double VANOS. Hoʻomalu ʻia ka mana mana e kahi mana Bosch DME ME me ka firmware 9.2.
Ua hoʻokomo ʻia ka ʻenekini i ka BMW 35i a hiki i ka hoʻomaka ʻana o ka mea hana kaʻa Kelemania e hoʻololi iā ia me kahi N2005B62 i hoʻolālā hou ʻia i ka makahiki 40.

N62B40
I ka like me ka mana nui N62B48, BMW Plant Dingolfing i hana i kona hoa, ka N62B40, i pani i ka N62B36 engine. ʻO ke kumu no ka hoʻomohala ʻana o kēia hoʻonohonoho ʻana ʻo ia ka N62B48, i ka BC kahi i hoʻokomo ʻia ai kahi crankshaft me ka 84.1 mm piston stroke a me nā cylinders me ke anawaena o 87 mm.
Ua loaʻa i ka N62B40 poʻo cylinder nā keʻena puhi ahi i hoʻomaikaʻi ʻia a me nā kiwi i hoʻololi ʻia no kahi hoʻokuʻu hou (me ka hoʻonui ʻia o ka pauku paipu). ʻO ka mea hana no ka hana ʻana o ke poʻo he alumini alumini me ke silicon - silumin. No ka N62B40 hoʻi, e hoʻokomo ʻia kahi hoʻokomo hou ʻelua me kahi ʻōnaehana DISA.
ʻO ka ʻōnaehana hoʻokele engine he mana Bosch ECU DME ME me ka firmware 9.2.2. Ua hoʻohana ʻia kēia kaʻa ma nā hiʻohiʻona BMW 40i.
Mai ka makahiki 2008, ua hoʻololi mālie ʻia ka ʻohana holoʻokoʻa o N62 powertrains e kahi pūʻulu hou o N63 turbocharged units.

Nā pōmaikaʻi a me nā pilikia o N62B36 a me N62B40
Плюсы
- ʻElua-VANOS/Bi-VANOS
- valvetronic
- mau
Минусы
- Maslozhor
- Nā kipi lana
- Leʻa ʻaila
Ma waena o nā hemahema nui o nā mīkini N62B36 a me N62B40, ʻike pinepine ʻia ka hoʻonui ʻana i ka aila. Hana ʻia kēia ma hope o ka holo ʻana o 100 tausani km. a ʻo ke kumu o nā mea a pau, ʻo ia ka hoʻopaʻa ʻana o ka pahu valve. Ma hope o hoʻokahi haneli kaukani mile, ʻaʻole i pau nā apo ʻaila.
ʻO nā kipi lele, ma ke ʻano he lula, ʻike ʻia ma muli o ka hemahema o ka coil ignition. Hiki iā ʻoe ke nānā i ka ʻōnaehana hoʻoili kinoea Valvetronic, ka hele ʻana o ka leaka o ka ea, ka mika kahe.
ʻO ka loaʻa ʻana o nā leaks aila, ma ke ʻano he kānāwai, ʻike ʻia ma muli o ka crankshaft seal a i ʻole ka mea hoʻoheheʻe hale. Eia kekahi, ʻo nā pūnaewele o nā catalysts e hāʻule i ka wā lōʻihi e pau i loko o nā cylinders, e hopena i ka helu ʻana. ʻO ka hopena maikaʻi loa i kēia hihia, ʻo ia ke hoʻololi i nā catalysts me nā mea hopu ahi.
Ma keʻano laulā, no ka lōʻihi o ka loaʻa ʻana o ka waiwai o nā mīkini N62B36 a me N62B40, a he liʻiliʻi nā pilikia me lākou e like me ka hiki, ʻoi aku ka maikaʻi o ka mālama ʻole ʻana i ka ʻaila a me ka wahie, a me ka mālama mau.
Hoʻokani i ka N62B36 a me N62B40
ʻO ke ala kūpono loa e hoʻokani i ka N62B36, ʻo ia ke kīpī i ka ʻōnaehana. Pono ʻoe: kahi hoʻopau haʻuki, kahi kānana haʻahaʻa haʻahaʻa a me kahi hoʻonohonoho maikaʻi o ka ECU ponoʻī. ʻO kēia mau mea a pau e hiki iāʻoe ke piʻi i ka 300 hp. a hāʻawi i ka mīkini maikaʻi dynamics. ʻAʻole kūpono ke hana i kahi mea ʻē aʻe, ʻoi aku ka maikaʻi ma mua o ka hoʻololi wale ʻana i ke kaʻa.
ʻAʻole maikaʻi ke kani maikaʻi ʻana o ka N62B40 no ke kālā kūpono, a eia ʻoe e koho ai: ʻo ka chipping a i ʻole ka turbocharger pipiʻi. ʻO ka uila ʻana i ka ʻāpana hoʻomalu, i hui pū ʻia me kahi kānana kūʻē kūʻē a me ka hoʻokomo ʻana i kahi ʻōnaehana hoʻokele haʻuki, hiki ke hāʻawi i 330-340 hp. a me ka manaʻo o ka ʻenekini hana ʻino.
hopena
I ka hōʻuluʻulu manaʻo, palekana ka ʻōlelo ʻana i nā ʻāpana mana N62, nona ka New Generation engine series, i lilo i mea pani maikaʻi no ka M62. Ke hoʻohālikelike ʻia i kona mea i hana mua ʻia, ua hoʻololi nui ʻia ka motika N62, ma ka mechanical a me ka digitally. Mahalo i nā mea hou a pau, ua hoʻokō nā mea ʻenekinia i ka hoʻonui ʻana i ka mana a hoʻomaikaʻi i ka torque, a me ka hōʻemi ʻana i ka hoʻohana ʻana i ka wahie a me nā hoʻokuʻu ʻino i ka lewa.
Ma kekahiʻaoʻao,ʻo ka hoʻomaikaʻiʻana a me nā mea hou i hana i ka hana o nā hanauna hou loa o nā mana mana iʻoi aku ka noʻonoʻo, akā ma kaʻaoʻao'ē aʻe, ua paʻakikī kēia mau mea a pau i kā lākou mau hoʻolālā, i lilo i "capricious". Pili kēia i nā ʻenekini N62B36 a me N62B40. ʻO kekahi o nā wahi pilikia loa ma ka N62 ʻo ia ka ʻōnaehana Double Vanos i ʻōlelo ʻia. ʻO kahi wahi nāwaliwali hoʻi ka mechanics o ka ʻōnaehana Valvetronic.
Ma ka International Powertrain Competition ma 2002, ua loaʻa ka N62B36 i nā poʻo inoa: "Best New Engine", "Best Engine of the Year", a ʻo ia hoʻi ka mea lanakila ma ka māhele: "Best 4-litre Engine".
