N46 injini - ruzivo rwekutanga

Chikwata ichi chakasiyana sei nechakatangira? Iyo N46 inoshandisa yakanyatsogadziridzwa crankshaft, manifold akawanda uye chitima chevharuvhu. Muna 2007, injini zvakare yakagadziriswa kuduku - iyi shanduro yakatengeswa pasi pezita rokuti N46N. Zvakasarudzwawo kushandura manifold etake, exhaust camshaft uye injini control unit (Bosch Motronic MV17.4.6). 

Magadzirirwo ekugadzirisa uye kupisa

Iyo modhi yaive zvakare yakashongedzerwa neValvetronic system, pamwe neiyo mbiri VANOS system, yaive nebasa rekudzora mavharuvhu. Kupisa kwakatanga kudzorwa uchishandisa lambda probes, iyo yakashandawo pamutoro mukuru. Mishonga yataurwa pamusoro apa yaireva kuti injini yeN46 yaishandisa mafuta mashoma uye yagadzira zvishoma zvinosvibisa zviri muchimiro cheCO2, HmCn, NOx nebenzene. Injini isina Valvetronic inozivikanwa seN45 uye yaiwanika mu1,6 uye 2,0 litres versions.

Data yehunyanzvi yesimba remagetsi

Dhizaini maficha anosanganisira aruminiyamu block, inline-mana kumisikidzwa, uye mana mavharuvhu eDOHC pacylinder ine 90mm bore uye 84mm sitiroko.

The compression reshiyo yaive 10.5. Vhoriyamu yose 1995 cc Mafuta epeturu akatengeswa neBosch ME 9.2 kana Bosch MV17.4.6 control system.

bmw injini kushanda

Iyo N46 injini yaifanira kushandisa 5W-30 kana 5W-40 oiri uye ichichinja yega 7 kana 10 zviuru zvemakiromita. km. Tangi inokwana marita 4.25. MuBMW E90 320i, payakaisirwa chikwata ichi, kushandiswa kwemafuta kwaichinja-chinja maererano nemaitiro anotevera:

• 7,4 l/100 km yakasanganiswa;
• 5,6 l / 100 km mumugwagwa mukuru;
• 10,7 l/100 km mubindu.

Tangi inokwana yakasvika 63 litres, uye CO02 emissions yaive 178 g / km.

Kuputsika uye kusashanda ndiwo matambudziko akajairika

Paive nekukanganisa mukugadzirwa kweN46 izvo zvakakonzera kukanganisa. Chimwe chezvainyanyozivikanwa chaive chakanyanya kushandiswa kwemafuta. Muchikamu chino, chinhu chinoshandiswa chinotora basa rinokosha - zviri nani hazvikonzeri matambudziko. Kana izvi zvikasatarisirwa, mavharuvhu stem seals uye piston zvindori zvinotadza - kazhinji ne50 km. km.

Vashandisi vemotokari zvakare vakakwevera kutarisa kune yakasimba vibrations uye ruzha rweyuniti. Zvaikwanisika kubvisa dambudziko iri nekuchenesa VANOS variable valve timing system. Mamwe mabasa akaomarara aidiwa kutsiva cheni yenguva, iyo inogona kutambanudza (kazhinji mushure me100 km). 

Drive tuning - mazano ekugadzirisa

Iyo mota ine zvakawanda zvinogoneka kana zvasvika pakugadzirisa. Munyaya iyi, imwe yesarudzo dzakajairika kune varidzi vemota dzine N46 injini ndeye chip tuning. Nekuda kweizvi, unogona kuwedzera simba rekutyaira nenzira iri nyore. Izvi zvinogona kuitwa uchishandisa aggressive ECU firmware. Iko kusimudzira kuchava kuwedzera kwemhepo inotonhora yekupinda, pamwe nekatsi-kumashure exhaust system. Kunyatsoitwa tuning kuchawedzera simba remagetsi unit kusvika ku10 hp.

Iwe unogona sei kuwedzera?

Imwe nzira ndeye kushandisa supercharger. Mushure mekubatanidza supercharger kune injini system, kunyange kubva pa200 kusvika ku230 hp inogona kuwanikwa kubva injini. Nhau dzakanaka ndedzekuti haufanirwe kuunganidza zvikamu zvega wega. Iwe unogona kushandisa kititi chakagadzirirwa kubva kune vanovimbika vanogadzira. Iyo chete yakaderera yeiyi mhinduro mutengo, dzimwe nguva unosvika pa20 XNUMX. zloty.

Kana uine chokwadi chekuti mota ine N46 injini iri mune yakanaka tekinoroji mamiriro, iwe unofanirwa kuisarudza. Mota uye madhiraivha anowana ongororo yakanaka, inovimbisa kutyaira mafaro pamwe nekuita kwakaringana uye hupfumi hwekushandisa. Iyo mukana zvakare mukana wekugadzirisa iyo BMW drive.
