ʻO ka mīkini M57 maikaʻi loa mai BMW - he aha ka mea i aloha nui ʻia ai ka ʻenekini BMW M57 3.0d e nā mea hoʻokele a me nā tuner?

He mea hoihoi loa i ka BMW, i mana'o 'ia he 'ano ha'uki maoli a nani ho'i, e ho'omaka ana i ka 'enekini diesel ma ka mākeke. A ʻo kahi mea like ʻole. Ua lawa ka ʻōlelo ʻana ua lanakila ka mīkini M4 i ke poʻo inoa o "Engine of the Year" 57 mau manawa i ka lālani! Aia kāna moʻolelo a hiki i kēia lā, a he nui ka ʻoiaʻiʻo i loko.

M57 engine - ka ʻikepili ʻenehana kumu

ʻO ka mana kumu o ka mīkini M57 he 3-lita a me 6-cylinder in-line block, uhi ʻia me kahi poʻo 24-valve. Loaʻa iā ia he 184 hp, i hāʻawi i ka hana maikaʻi loa ma ka moʻo BMW 3. Ua ʻoi aku ka maikaʻi o kēia ʻāpana i ka moʻo 5 nui a me nā hiʻohiʻona X3.

I ka manawa lōʻihi, ua hoʻololi ʻia nā mea ʻenehana, a ʻo nā ʻano hou loa he 2 turbocharger a me ka mana o 306 hp. Hoʻokomo ʻia ka wahie ma o kahi ʻōnaehana kaʻaahi maʻamau i hōʻike ʻole i nā hōʻailona o ka nāwaliwali ke hoʻopiha ʻia me ka wahie maikaʻi. ʻO ka turbocharger me nā geometry lau ʻokoʻa a me ka huila lua-nui nā mea hana diesel nui o ia mau makahiki.

BMW M57 3.0 - he aha ka mea kū hoʻokahi?

ʻO kēia, ʻo ka mea mua, ʻoi aku ka lōʻihi a me ka manawa mālama ʻole. ʻOiai ʻo ka torque i nā ʻano nāwaliwali loa i ka pae o 390-410 Nm, ua mālama maikaʻi ke kaʻa iā ia. ʻO ka ʻōnaehana crank-piston holoʻokoʻa, pahu pahu a me nā mea hoʻoili ʻē aʻe i hoʻohālikelike pono ʻia i ka mana i hana ʻia e kēia ʻāpana. ʻAʻole ia he mea nui inā ʻo ka 3rd series (no ka laʻana, E46, E90) a i ʻole ka 5th series (no ka laʻana, E39 a me E60) - i kēlā me kēia mīkini, hāʻawi kēia hoʻolālā i ka hana maikaʻi loa. I nā makahiki mua o ka hana ʻana, ʻaʻohe kānana DPF i hoʻokomo ʻia i ka ʻōnaehana exhaust, a hiki i ka manawa ke alakaʻi i kekahi mau hana hewa.

ʻO ka mīkini M57 i ka BMW 3.0d a me kona hiki ke kani

Hōʻike nā mana buffs i nā mana 330d a me 530d he mau kaʻa hoʻokani maikaʻi. ʻO ke kumu ka lōʻihi kiʻekiʻe loa o ka ʻōnaehana hoʻokele kaʻa a me ka ʻike kiʻekiʻe i nā loli i ka mea hoʻokele kaʻa. Hiki iā ʻoe ke unuhi maʻalahi ma luna o 215 horsepower mai ka mana nāwaliwali loa me hoʻokahi papahana. ʻO ka ʻōnaehana Common Rail a me nā twin turbochargers ke kumu kūpono no ka hana ʻoi aku ka maikaʻi. ʻO 400 hp, ana ʻia ma kahi dyno me ka ʻole o ka hana nui ʻana i nā lāʻau hoʻohui a me nā pistons, ʻo ia ka hana maʻamau o nā tuners. Ua loaʻa kēia i ka moʻo M57 i kaulana no ka pale ʻana a kaulana loa i ka motorsport.

Ua haki ka mīkini BMW M57?

Pono e ʻae ʻia he drawback ka 3.0d M57 - he mau swirl flaps kēia i hoʻokomo ʻia ma nā ʻano ʻekolu-lita wale nō. ʻAʻole i loaʻa i nā ʻano like ʻole 2.5 i loko o ka intake manifold, no laila ʻaʻohe pilikia me kēlā mau hoʻolālā. I ka hoʻomaka ʻana o ka hana ʻana, ʻoi aku ka liʻiliʻi o ka mana o ka mīkini M57 e haki. ʻAʻole paʻakikī ke koho ʻana i kahi ʻāpana o ka mea i hāʻule i loko o ke keʻena puhi ahi hiki ke hoʻopōʻino nui i nā valves, pistons a me nā liner cylinder. I nā mana hou (mai ka makahiki 2007), ua hoʻololi ʻia kēia mau puka me nā puka nui i haki ʻole, akā ʻaʻole mālama mau i ko lākou paʻa. No laila ʻo ke ala maikaʻi loa e hoʻopau iā lākou.

ʻO nā glitches ʻē aʻe o ka diesel armored 3.0d

He mea paʻakikī ke manaʻo ʻaʻole e wāwahi ka mīkini M57, i loaʻa ma ka mākeke lua no nā makahiki he nui. Ma lalo o ka mana o nā makahiki he nui o ka hana, ua hāʻule kekahi injector a i ʻole kekahi mau manawa. ʻAʻole ʻoi aku ke kumukūʻai o kā lākou hana hou ʻana, ʻo ia ka mea e pili ana i ka mālama ʻole a me ka wikiwiki. Hōʻike kekahi mau mea hoʻohana e pilikia paha nā thermostats i ka manawa. ʻO ka manawa maʻamau he 5 mau makahiki, ma hope o ka manawa e hoʻololi ʻia. ʻO ka mea nui, ʻaʻole pilikia ka kānana DPF e like me nā kaʻa ʻē aʻe. ʻOiaʻiʻo, pono e hoʻomanaʻo i nā lula kumu no ka puhi ʻana.

ʻO ke kumukūʻai o ka lawelawe ʻana i kahi kaʻa me ka mīkini M57

Ke hoʻolālā nei ʻoe e kūʻai i kahi mana 184 hp, 193 hp a i ʻole 204 hp - ʻaʻole pono e hoʻoweliweli iā ʻoe nā koina hana. Ma ke alanui, ho'opau ka 3-lita ma kahi o 6,5 l/100 km. I loko o ke kūlanakauhale me kahi ʻano hoʻokele ikaika, hiki i kēia waiwai ke pālua. ʻOiaʻiʻo, ʻoi aku ka ikaika o ka ʻāpana a me ke kaumaha o ke kaʻa, ʻoi aku ka kiʻekiʻe o ka hoʻohana ʻana i ka wahie. Eia naʻe, maikaʻi loa ka lakio o ka hoʻohana wahie i ka dynamics a me ka leʻaleʻa hoʻokele. E hoʻomanaʻo i ka hoʻololi ʻana o ka aila maʻamau i kēlā me kēia 15 km a me nā lula kumu no ka hoʻokele diesel, a e lawelawe ia iā ʻoe no nā makahiki he nui. Aia nā ʻāpana kūʻai ma ka papa kumu kūʻai maʻamau - ʻoiaʻiʻo, ke kamaʻilio nei mākou e pili ana i ka pae o BMW.

He mea kūpono ke kūʻai aku i BMW me ka mīkini M57?

Inā loaʻa iā ʻoe ka manawa kūpono e kūʻai i kope i mālama maikaʻi ʻia me ka mōʻaukala i hōʻoia ʻia, mai kali lōʻihi. He koho maikaʻi loa ka BMW me kēia mīkini, ʻoiai inā he 400 km.
