BMW N73B60, N74B60, N74B66 injini

BMW injini N73B60, N74B60, N74B66 mhando dzakavandudzwa dzeinjini dzakakurumbira dzeBMW 7 Series muE65, E66, E67 uye E68 masitaera emuviri, pamwe neRolls-Royce.

Injini yega yega chizvarwa chinotevera chemuenzaniso wekare: ese mamotor anoshanda pane imwechete musimboti uye ane fungidziro yehunyanzvi hunhu, inosiyana chete mune inofungisisa dhizaini.

Kubudirira uye kugadzirwa kweBMW N73B60, N74B60, N74B66 injini: zvaive sei?

Kugadzirwa kweinjini muhuwandu hwakakura kwaienderana nekugadzirwa kwe7 Series BMW. Kuvandudzwa kwekutanga kweBMW N73B60 kwakatanga mukutanga kwe2000, uye injini pachayo yakapinda mukugadzirwa muna 2004 uye yakabudiswa kusvika 2009, mushure mokunge yakatsiviwa nechizvarwa chakatevera N74B60 uye N74B66.

Parizvino, kugadzirwa kweinjini kunoenderera mberi uye zvikamu zvepakutanga uye zvikamu zvakasara analogues zvinogona kuwanikwa zvakasununguka pamusika wechipiri wemotokari. Pasinei nesimba guru, injini yakarongedzerwa nereplica mutengesi zvikamu izvo zvisingapfupise hupenyu hwebasa kana simba - iyo BMW N73B60, N74B60, N74B66 modhi imari yakanaka kune vanoda simba.

Izvi zvinonakidza! Injini imwe neimwe munhevedzano yakagadzirwa maererano nekugadzirwa kwayo, asi zvikamu zvechizvarwa chekare zvakashandiswa pakugadzira. Iyi nhanho yakaita kuti zvikwanise kubatanidza dhizaini, kufambisa danho rekugadzira uye kubvisa zvese zvisina simba zvemhando dzekare.

Unyanzvi hunhu: chii chakafanana mumamodeli

Iyo yese nhevedzano yeinjini i12-cylinder injini dzakagadzirwa paV-shaped architecture. Zvese zvikamu zvinogadzirwa nealuminium, uye zvikamu zvemuviri uye CPG zvinoenderana nechero chizvarwa cheinjini, iyo yakawedzera kuchengetedza uye yakaderedza mutengo wekugadzirwa kwezvikamu. Zvakare, pakati pezvakajairika maficha muBMW N73B60, N74B60, N74B66 injini, zvinotevera zvinofanirwa kujekeswa:

• High-precision mafuta jekiseni system;
• Iyo yakazvimirira sisitimu yepiezoelements inopa kupisa;
• Peya yezvidziviriro zvemhepo zvinoshanda zvinoenderana nemusimboti wekunangana kuburikidza ne-inflating nekutonhora kusinganangi;
• Vacuum system ine nhanho mbiri yekutsvaira pombi;
• Kaviri-VANOS system.

Chizvarwa chega chega chenhevedzano chakashongedzerwa neyakasarudzika mafuta uye crankcase ventilation system, uye zvakare yaive neyakagadziridzwa dhizaini yemacamshafts uye toothed roller cheni. Zvakare, iyo yese mutsara wemidziyo yemagetsi inokonzeresa kufanana kwemafuta ekupa uye kudzima frequency yaive pasi pekushandurwa.

Imwe neimwe yeinjini yaive neyayo otomatiki kutapurirana, asi iyo bhajeti shanduro yeGerman 7 Series yaive neyakajairwa ZF 8HP. Nhamba yeVIN yeinjini yefekitari yakadhindwa pachivharo chepamusoro cheinjini pakati pemidziyo yekusveta mhepo yemachaja makuru.

Kushaya simba kwenhevedzano: kupi kutarisira kuparara

Kugadzira injini yega yega kubva pakutanga kwakaita kuti zvibvirire kudzikisa huwandu hwekusagadzikana mumagadzirirwo emota yega yega, zvisinei, kunyangwe yakafungwa-yakanyatso hunyanzvi hwekuvakisa, mapundu mumamotors akazarurwa panguva yekushandiswa kwakanyanya. Izvo zvakanyanya kuipa kweBMW N73B60, N74B60, N74B66 yakacherechedzwa isati yavimbiswa hupenyu hwesevhisi:

• Kumhanya kunoyangarara pasina basa - nekuda kwezvimiro zveValvetronic system, injini payakasvika tembiricha yekushanda isina basa, vibration mutoro wakawedzera, izvo zvakakonzera kuvhunduka kwakasimba kwakakanganisa kugadzikana kwemafuta. Kusashanda uku ndiko kukanganisa kwekugadzira uye kwakabviswa chete nekugadzirwa kwechikwata chitsva chekugadzira;
• Iyo yakaoma dhizaini yebhanhire renguva inoreva kuti bhandi remota rinotapukirwa nekunetseka kwakanyanya kwekushisa, izvo zvinoda kugara uchigadzirisa. Zvinokurudzirwa kushandura nguva bhandi musangano zvikamu ose 80-100 km;
• Engine decompression - mamiriro ezvinhu anokonzerwa nekuputsika kwekusimba kwekutora turakiti, iyo inogadziriswa nekutsiviwa nenguva yeo-mhete uye sealant;
• Kukundikana kwe cylinder block - iyo injini yese system inoshanda pahwaro hwemaviri ekudzora mayuniti, uye kana imwe ikaputsika, nhamba yese yemasilinda inodzimwa.

Dhizaini yeBMW N73B60, N74B60, N74B66 injini yairatidzwa nezvikamu zvakawanda zvinofamba zvakawedzera kupisa kweinjini. Kuti udzivise kupisa kweinjini, zvinokurudzirwa kushandura zvachose inotonhorera makore maviri ega ega nekumanikidza kutsvaira sisitimu.

Kugona kwekugadzirisa

Nekuda kweiyo yakaoma dhizaini base, kunze kupindira nezvikamu zveinjini kunorambidzwa nemugadziri - zvinhu zvakawanda zvakagadziridzwa zvinokanganisa hupenyu hwesevhisi yeinjini uye zvinokonzeresa kugadzirisa kunodhura.

Iyo chete nhanho inonzwisisika yekuwedzera kushanda kweinjini ndeye chip tuning: kuvhenekazve midziyo yemagetsi inobvumidza iwe kudzikamisa kupihwa kwemafuta nekugadzirisa injini kusvika pakumhanya kwakanyanya kana torque. Yemagetsi firmware inokutendera iwe kuti uwedzere injini simba kune 609 bhiza pasina kurasikirwa nehupenyu hwesevhisi - kunyangwe injini yakavharwa mukudzidzira inovhara 400 km pasina kudiwa kwekugadzirisa kukuru.

Muchidimbu pamusoro pechinhu chikuru

Iyo mhando yemhando yeBMW 7 Series BMW N73B60, N74B60, N74B66 ndiyo embodiment yedhizaini yakavimbika uye simba repamusoro. Injini dzine mwero uye dzakasimba, asi dzinoda kugadziridzwa nguva dzose.

Iyo turbocharged V12 yakatevedzana yakakodzera kune vanoda mota dzine simba vasina hanya nemutengo wekugadzirisa uye mutengo wezvikamu, uye injini hadzina kukodzera kushandiswa kwezuva nezuva.
