ʻEnekini BMW N46B18
Nā mea
ʻO ka'ōpiopio loa o ka laina N46 powertrain - N46B18, ua hanaʻia ma ke kumu o ka N46B20 a ua hanaʻia mai ka makahiki 2004, a no nā kaʻa BMW E46 316 wale nō. Ua wehe loa ʻia nā hiʻohiʻona E2006 mai ka laina hui, a ʻaʻole i loaʻa i kēia mīkini ka manawa e loaʻa ai ka mahele nui.
ʻO N46B18 ka mea i manaʻo mua ʻia ma ke ʻano he pani no kona mua - N42B18, a loaʻa iā ia kahi crankshaft i hoʻololi ʻia, nā kumu kaulike i hoʻololi ʻia a me nā koʻokoʻo hoʻohui, a me nā mea ʻokoʻa loa: kahi uhi poʻo cylinder a me kahi tensioner kaulahao manawa. Ua loaʻa i ka N46B18 (mea hou): intake manifold, alternator a me nā pahu kukui.
ʻAʻole like me ka N46 maʻamau, ʻo kāna ʻano hoʻololi 1.8-lita: he crankshaft i loaʻa i kahi kī pōkole (81 mm); nā pistons ma lalo o ka compression ratio 10.2; ʻohi maʻamau - me ka ʻole DISA. Ua hoʻohui ʻia ʻo Valvetronic i ka ʻōnaehana Bosch ME 9.2.
ʻO ka mana mana N46B18, e like me kona mana 2-lita, he nui nā hiʻohiʻona pili i hana ʻia ma kahi kumu like.
I ka makahiki 2011, ʻo ka N46B18, akā naʻe, a me ke koena o ka ʻaila i loko o ka laina "ʻehā" mai BMW, ua hoʻololi ʻia e kahi mīkini N13B16 turbocharged hou, i hana ʻia i nā hoʻololi like ʻole a hiki i kēia manawa.

- Hoʻokomo ʻia
- ʻO ka pahu pahu pahu
- Hiki ke hoololi
ʻAla:
- Hoʻonui ʻia ka hoʻohana ʻana a me ka ʻaila ʻaila
- walaʻau ʻenekini, haʻalulu
- ʻO nā pilikia me ka Valvetronic, ka ʻaila pauma, CVCG a me ka pauma ʻūhā
ʻO ke kumu nui o ke ʻano o ka mea puhi aila i ka N46B18, e like me ka mīkini 42nd, ʻo ia ka hoʻohana ʻana i ka aila mīkini haʻahaʻa haʻahaʻa. Eia kekahi, aia paha ka pilikia i nā sila valve hāʻule.
Hana ʻia kēia ma hope o ka holo ʻana o 50-100 tausani km. ʻO ka aila ʻaʻole i ʻōlelo ʻia e ka mea hana e komo i nā pilikia hou aʻe. No ka laʻana, me ka Valvetronic like, ʻaila pauma, crankcase ventilation valve a pēlā aku. I kēia hihia, ʻaʻole pono ka mālama ʻana i ka mālama.
Eia kekahi, ma hope o ka holo ʻana o 50 tausani km, e noi ʻia ke poʻo cylinder head gasket a me ka pauma ʻūhā no ke pani.
ʻO nā kumu o ka haʻalulu a me ka walaʻau ʻana o ka ʻenekini ma ke ʻano ma ke kaulahao manawa a i ʻole ma ke kaulahao lohi. Ma hope o ka holo ʻana o 100-150 tausani km, ʻaʻole maʻamau kēlā mau pilikia.
No ka ho'ēmiʻana i ka pilikia me ka mīkini, pono e hoʻololi i kaʻaila i ka manawa, a iʻole ka pinepine, pono e hana mua a'ōleloʻia e ka mea hana. Eia kekahi, he mea nui e ninini i ka ʻaila maikaʻi a mālama i ka mālama i ka manawa kūpono.
Hiki ke hoʻopaʻa ʻia
Eia nō hoʻi, e like me nā ICE 4-cylinder liʻiliʻi liʻiliʻi, maikaʻi ka N46B18 no ka hoʻololi ʻana, akā ʻaʻole kūpono ia no ke kani ʻana a ʻo ke ala kūpono wale nō e hoʻonui ai i ka mana inā ʻo ia ka hoʻokani pila. ʻO ka mea nui loa, e hoʻokomo ʻia kahi kānana kūʻokoʻa ʻole i loko o ke keʻena tuning, e alakaʻi ʻia i ka bumper mua, e ʻoki ʻia ka catalyst a e hoʻopau hou ʻia ka ʻōnaehana. E hoʻohui kēia mau mea i ka dynamics a loaʻa iā +10 hp. No kekahi mea hou aʻe, pono ʻoe e kau i ka ʻenekini ma 6 cylinders.
