BMW N46 injini - deta luso, zosokonekera ndi makonda powertrain

Injini ya N46 yochokera ku kampani yaku Bavaria ndiyomwe yalowa m'malo mwa gawo la N42. Kupanga kwake kudayamba mu 2004 ndikutha mu 2015. Zosiyanasiyana zidalipo m'mitundu isanu ndi umodzi:

• N46B18;
• B20U1;
• B20U2;
• B20U0;
• B20U01;
• NB20.

Muphunzira zambiri za injini iyi pambuyo pake m'nkhani yathu. Onani ngati mafani akusintha angakonde chipangizochi!

N46 injini - zambiri zofunika

Kodi gawoli likusiyana bwanji ndi zomwe zidalipo kale? N46 imagwiritsa ntchito crankshaft yokonzedwanso, yolowera komanso masitima apamtunda. Mu 2007, injini nayenso anamangidwanso zazing'ono - Baibulo linagulitsidwa pansi pa dzina N46N. Komanso anaganiza kusintha kudya zobwezedwa, utsi camshaft ndi injini ulamuliro wagawo (Bosch Motronic MV17.4.6). 

Mayankho a zomangamanga ndi kuyatsa

Chitsanzocho chinalinso ndi dongosolo la Valvetronic, komanso njira yapawiri ya VANOS, yomwe inali ndi udindo woyang'anira ma valve. Kuyaka kunayamba kuwongoleredwa pogwiritsa ntchito ma probe a lambda, omwe adagwiranso ntchito pakulemetsa kwakukulu. Mayankho omwe tawatchulawa amatanthauza kuti injini ya N46 idadya mafuta ochepa komanso imatulutsa zowononga zochepa monga CO2, HmCn, NOx ndi benzene. Injini yopanda Valvetronic imadziwika kuti N45 ndipo idapezeka mumitundu ya 1,6 ndi 2,0 lita.

Deta yaukadaulo yamagetsi

Mapangidwe ake amaphatikizapo chipika cha aluminiyamu, masinthidwe apakati-anayi, ndi mavavu anayi a DOHC pa silinda yokhala ndi 90mm bore ndi 84mm stroke.

Compress ratio inali 10.5. Chiwerengero chonse cha 1995 cc Gawo la mafuta lidagulitsidwa ndi makina owongolera a Bosch ME 9.2 kapena Bosch MV17.4.6.

ntchito ya injini ya bmw

injini N46 anayenera kugwiritsa ntchito 5W-30 kapena 5W-40 mafuta ndi kusintha 7 kapena 10 zikwi makilomita. km. Kutha kwa thanki kunali malita 4.25. Mu BMW E90 320i, yomwe idayikidwapo, kugwiritsa ntchito mafuta kumasinthasintha motsatira mfundo zotsatirazi:

• 7,4 L / 100 Km wosakanikirana;
• 5,6 L / 100 Km pa msewu waukulu;
• 10,7 l/100 Km m'munda.

Thanki mphamvu anafika malita 63, ndi mpweya CO02 anali 178 g/km.

Kusweka ndi kusagwira ntchito bwino ndizovuta kwambiri

Panali zolakwika pamapangidwe a N46 zomwe zidapangitsa kuti zikhale zovuta. Chimodzi mwazofala kwambiri chinali kugwiritsa ntchito mafuta ambiri. Pambali iyi, chinthu chomwe chimagwiritsidwa ntchito chimakhala ndi gawo lalikulu - zabwinoko sizimayambitsa mavuto. Ngati izi sizikusamalidwa, zosindikizira za valve ndi mphete za pistoni zimalephera - nthawi zambiri ndi 50 km. km.

Ogwiritsanso ntchito magalimoto adawonetsanso kugwedezeka kwamphamvu ndi phokoso la unit. Zinali zotheka kuchotsa vutoli poyeretsa VANOS variable valve timing system. Ntchito zovuta kwambiri zimafunikira m'malo mwa unyolo wanthawi, womwe umatha kutambasula (nthawi zambiri pambuyo pa 100 km). 

Kusintha kwagalimoto - malingaliro osintha

Galimoto ili ndi kuthekera kochuluka ikafika pakukonza. Pankhani iyi, imodzi mwazosankha zodziwika bwino za eni magalimoto okhala ndi injini ya N46 ndikusintha kwa chip. Chifukwa cha izi, mutha kuwonjezera mphamvu yagalimoto m'njira yosavuta. Izi zitha kuchitika pogwiritsa ntchito firmware yankhanza ya ECU. Chitukukocho chidzakhala chowonjezera cha mpweya wozizira, komanso makina otsekemera amphaka. Kukonzekera bwino kumawonjezera mphamvu yamagetsi mpaka 10 hp.

Kodi mungayimbenso bwanji?

Njira ina ndiyo kugwiritsa ntchito supercharger. Pambuyo kulumikiza supercharger ku dongosolo injini, ngakhale kuchokera 200 mpaka 230 HP akhoza analandira kuchokera injini. Nkhani yabwino ndiyakuti simuyenera kusonkhanitsa zigawozo nokha. Mutha kugwiritsa ntchito zida zopangidwa kale kuchokera kwa opanga odalirika. Choyipa chokha cha yankho ili ndi mtengo, nthawi zina umafika mpaka 20 XNUMX. zloti.

Ngati mukutsimikiza kuti galimoto yokhala ndi injini ya N46 ili mumkhalidwe wabwino waukadaulo, muyenera kusankha. Magalimoto ndi magalimoto amapeza ndemanga zabwino, zimatsimikizira kuyendetsa bwino komanso kuyendetsa bwino komanso kuyendetsa bwino ntchito. Ubwino ndi kuthekera kwa ikukonzekera BMW pagalimoto.
