BMW M62B44, M62TUB44 engines
Nā mea
I ka makahiki 1996, ua puka mai ka mo'olelo hou o BMW M62 ma ka mākeke honua.
'O kekahi o na 'enekini hoihoi loa 'o ia ka mo'olelo - 'o ka BMW M62B44 ewalu cylinder me ka nui o 4,4 lita. Ua lawelawe ʻia kahi ʻenekini M60B40 ma ke ʻano he ʻano prototype no kēia ʻenekini hoʻopau i loko.
Wehewehe ʻenekini
Inā ʻoe e nānā, a laila ma ka M62B44 hiki iā ʻoe ke ʻike i nā ʻokoʻa he nui mai ka M60B40. Eia kekahi o lākou:
- Ua loli ka poloka cylinder e like me nā anawaena hou o kēia mau cylinders.
- Aia kekahi crankshaft hou i hana ʻia me ke kila, lōʻihi-stroke, me ʻeono counterweights.
- Ua loli nā ʻāpana o nā camshafts (phase 236/228, hāpai 9/9 millimeters).
- Ua hoʻololi ʻia ke kaulahao manawa ʻelua lālani me kahi lālani hoʻokahi, me kahi kumu waiwai ma kahi o ʻelua haneli tausani kilomita.
- Ua hōʻano hou ʻia nā pahu throttle a ua hoʻololi ʻia ka intake manifold.
Akā he nui nā mea i hoʻololi ʻole ʻia. No laila, no ka laʻana, ʻaneʻane like nā poʻo cylinder M62B44 me nā poʻo i loaʻa ma nā ʻāpana M60. Hoʻohana like ia i nā koʻokoʻo hoʻohui a me nā kiwi (e hoʻomaopopo: ʻo ke anawaena o nā kiwi hoʻokomo ma aneʻi he 35 millimeters, a ʻo nā pahu hoʻopau he 30,5 millimeters).
Ma waho aʻe o ka mana maʻamau o kēia mīkini, aia kahi mana i loaʻa i kahi hoʻonui ʻenehana - ua loaʻa iā ia ka inoa M62TUB44 (aia kekahi ʻano ʻē aʻe M62B44TU, akā ʻo ia ka mea like) a ʻike ʻia ma ka mākeke ma 1998. I ka wā o ka hōʻano hou (hōʻano hou), ua hoʻohui ʻia ka ʻōnaehana hoʻokele hoʻoili kinoea VANOS i ka ʻenekini. Mahalo i kēia ʻōnaehana, hana maikaʻi ka ʻenekini ma nā ʻano āpau a loaʻa ka traction maikaʻi. Eia kekahi, mahalo iā VANOS, hoʻonui ʻia ka pono a hoʻomaikaʻi ʻia ka hoʻopiha cylinder. I loko nō hoʻi o ka mana i hoʻonui ʻia i ka ʻenehana i loaʻa kahi throttle uila a me kahi intake manifold me nā ala ākea liʻiliʻi. Ua hoʻolako ʻia ka ʻōnaehana Bosch DME M7,2 ma ke ʻano he ʻōnaehana mana no ka mana hou.
Eia hou, i loko o TU engines, cylinder liners hoʻomaka e hana 'aʻole mai nikasil e like me ka mea ma mua (nikasil he kūikawā nickel-silicon alloy i hoʻomohala ʻia e nā mea hana Kelemania), akā mai ka alusil (he alloy e pili ana i 78% alumini a me 12% silicon).
ʻO kahi pūʻulu hou o nā mīkini BMW me kahi hoʻonohonoho V8 - ka N62 series - i komo i ka mākeke ma 2001. ʻO ka hope loa, ma hope o kekahi mau makahiki, ua hoʻopau kēia i ka hana ʻana i nā ʻāpana like, akā ʻoi aku ka liʻiliʻi o ka holomua mai ka ʻohana M.

Hiki ke loaʻa ka helu engine M62B44 a me M62TUB44 i ka hāʻule, ma waena o nā poʻo cylinder, ma lalo o ka throttle. No ka ʻike ʻana, pono ʻoe e wehe i ka uhi plastik pale a nānā i kahi paepae liʻiliʻi ma ka ʻaoʻao waena o ka poloka. No ka hoʻomaʻamaʻa ʻana i ka ʻimi, ʻōlelo ʻia e hoʻohana i ke kukui uila. Inā ʻaʻole hiki iā ʻoe ke ʻike i ka helu ma ka hoʻāʻo mua, a laila pono ʻoe e wehe, i ka hoʻohui i ka pahu, a me ka throttle. Hiki iā ʻoe ke ʻike i nā helu o kēia mau ʻenekini ma ka "lua". Aneane ʻane lepo kēia lumi ma ʻaneʻi, ʻoiai e ahu pono ka lepo ma luna.
He aha nā kaʻa ʻo M62B44 a me M62TUB44
Ua hoʻokomo ʻia ka mīkini BMW M62B44 ma:
- BMW E39 540i;
- БМВ 540i Palekana E39;
- BMW E38 740i/740iL;
- BMW E31 840Ci.
Ua hoʻohana ʻia kahi mana hou o ka BMW M62TUB44 ma:
- BMW E39 540i;
- BMW E38 740i/740iL;
- BMW E53 X5 4.4i;
- Morgan Aero 8;
- Land Rover Range Rover III.
He mea pono e hoʻomaopopo i ka Morgan Aero 8 ʻaʻole ia he kaʻa haʻuki i hana ʻia e BMW, akā na ka hui Pelekane ʻo Morgan. A ʻo ka Land Rover Range Rover III kekahi kaʻa i hana ʻia e Pelekane.
ʻO nā hemahema a me nā pilikia maʻamau o nā mīkini BMW M62B44
Nui nā pilikia koʻikoʻi e hōʻike ʻia e ka poʻe kaʻa e hoʻokele kaʻa me nā ʻenekini i wehewehe ʻia:
- Hoʻomaka ka ʻenekini M62 e kīkēkē. ʻO ke kumu o kēia, no ka laʻana, he kaulahao manawa lōʻihi a i ʻole ka pahu tensioner.
- Ma ka M62, hoʻomaka ka leak o ka pahu uhi uhi, a me ka waihona hoʻomaha. Hiki iā ʻoe ke hoʻoponopono i kēia pilikia ma ke ʻano maopopo - hoʻololi i ka pahu pahu, intake manifold gaskets a me ka pamu.
- Hoʻomaka ka mana o ka M62B44 e hana me ka ʻole a me ka paʻa (ua kapa ʻia kēia ʻo "floating speed"). Hoʻopili ʻia ka hanana ʻana o kēia pilikia, ma ke ʻano he kānāwai, me ke komo ʻana o ka ea i loko o ka intake manifold. Hiki ke kumu ia ma muli o nā hemahema o ka KVKG, nā mea ʻike throttle, nā mika kahe o ka ea. ʻO ka hoʻohaumia maʻamau o nā kīwaha throttle hiki ke hana i ka wikiwiki paʻa ʻole.
Ma luna o kēlā, ma hope o 250 tausani mau kilomita, hoʻonui ka hoʻohana ʻana i ka aila ma ka M62 (no ka hoʻoponopono ʻana i kēia pilikia, ua ʻōlelo ʻia e hoʻololi i nā sila o ka valve stem). Eia kekahi, ma hope o 250 tausani mau kilomita, hiki ke haʻalele ʻia nā puʻu mīkini.
Hoʻolālā ʻia nā mana mana M62B44 a me M62TUB44 e launa pū me ka aila kiʻekiʻe - ʻoi aku ka maikaʻi o ka hoʻohana ʻana i nā hōʻailona i ʻōlelo ʻia e ka mea hana ponoʻī. ʻO kēia nā aila 0W-30, 5W-30, 0W-40 a me 5W-40. Akā, pono e ho'ohana 'ia ka aila i kaha 'ia me 10W-60 me ka mālama 'ana, 'o ia ho'i i ka ho'oilo - he mānoanoa, a i nā mahina anu o ka makahiki, pilikia paha ka ho'omaka 'ana i ka mīkini. Ma keʻano laulā, ʻaʻole ʻōlelo ka poʻe loea i ka mālama ʻana i nā wai hana inā he mīkini M62 ke kaʻa. ʻAʻole pono ka haʻalele ʻana i ka mālama ʻana a me ka mālama manawa.
ʻO ka hilinaʻi a me ka mālama ʻana o ka BMW M62B44
M62B44 kaʻa (ke kumu a me ka mana TU) e hōʻike ana i kahi kiʻekiʻe o ka hilinaʻi a me ka palekana. Ma waho aʻe o kēia, he traction maikaʻi loa ia ma nā revs haʻahaʻa, a ma nā ʻano hana ʻē aʻe. ʻO ke kumu waiwai o kēia kaʻa, me ka mālama pono, hiki ke lanakila i ka hōʻailona o 500 tausani mau kilomita.
Ma keʻano laulā, kūpono ke kaʻa no ka hoʻoponopono kūloko a me ka hoʻoponopono nui. Eia naʻe, loaʻa iā ia nā pilikia āpau o nā mīkini alumini māmā i uhi ʻia me ka nikasil a me ka alusil. I loko o kahi ʻoihana ʻoihana, kapa kekahi i kēlā mau motika "disposable". ʻO ka mea mahalo, ua manaʻo ʻia nā poloka silinder alusil ma mua o nā nikasil - ʻo ia hoʻi, ʻo ka TU-variation kekahi mau pono i kēia ʻano.
Ke kūʻai ʻana i kahi kaʻa i hoʻohana ʻia me kēia ʻenekini, ʻōlelo ʻia e ʻike koke i ka mīkini a hoʻopau i nā hewa āpau i ʻike ʻia. ʻO ia ʻano hoʻopukapuka e ʻae iā ʻoe e manaʻo nui aʻe ma hope o ka huila.
nā koho hoʻokani
ʻO ka poʻe makemake e hoʻonui i ka mana o ka BMW M62TUB44 e hoʻokomo mua i kahi intake manifold me nā ala ākea i kēia mīkini (no ka laʻana, mai ka mana kumu).
Pono nō hoʻi e hoʻokomo i nā camshafts ʻoi aku ka maikaʻi ma aneʻi (no ka laʻana, me nā hōʻailona o 258/258), kahi hāmeʻa exhaust manifold a hana i nā hoʻololi. ʻO ka hopena, hiki iā ʻoe ke loaʻa ma kahi o 340 horsepower - lawa kēia no ke kūlanakauhale a me ke ala. ʻAʻohe kumu i ka ʻoki wale ʻana i nā mīkini M62B44 a i ʻole M62TUB44 me ka ʻole o nā ana ʻē aʻe.
Inā makemake ʻia ka mana no 400 horsepower, a laila pono e kūʻai ʻia kahi pahu compressor a hoʻokomo. Nui nā pahu i loaʻa i nā hale kūʻai pūnaewele a me waho i kūpono i ka hui piston BMW M62 maʻamau, akā ʻaʻole nā kumukūʻai haʻahaʻa. Ma waho aʻe o ka pahu compressor, pono e kūʻai ʻia kahi paila Bosch 044. ʻO ka hopena, inā hiki ke kaomi o 0,5 bar, e ʻoi aku ka nui o ka 400 horsepower.
ʻO ka mālama ʻana no ka hoʻokani ʻana, e like me ka poʻe loea, ma kahi o 500 horsepower. ʻO ia hoʻi, maikaʻi kēia ʻenekini no ka hoʻokolohua me ka mana.
E like me ka turbocharging, i kēia hihia ʻaʻole ia he waiwai nui mai ka ʻike waiwai. E 'oi aku ka ma'alahi o ka ho'ololi 'ana o ka mea ho'okele i kekahi ka'a like 'ole - i ka BMW M5.
