Injini ye-BMW N46 - idatha yobuchwepheshe, ukungasebenzi kahle kanye nezilungiselelo ze-powertrain
Okuqukethwe
Injini ye-N46 evela enkampanini yaseBavaria ilandela uphiko lwe-N42. Ukukhiqizwa kwayo kwaqala ngo-2004 futhi kwaphela ngo-2015. Okuhlukile bekutholakala ngezinguqulo eziyisithupha:
- I-N46B18;
- B20U1;
- B20U2;
- B20U0;
- B20U01;
- NB20.
Uzofunda okwengeziwe ngale injini kamuva esihlokweni sethu. Hlola ukuthi abalandeli bokushuna bazoyithanda yini le divayisi!
Injini ye-N46 - ulwazi oluyisisekelo
Le yunithi ihluke kanjani kweyandulelayo? I-N46 isebenzisa i-crankshaft eklanywe kabusha ngokuphelele, i-intake multifold kanye nesitimela samavalvu. Ngo-2007, injini nayo yavuselelwa kancane - le nguqulo yathengiswa ngaphansi kwegama elithi N46N. Kuphinde kwanqunywa ukuthi kushintshwe i-multifold intake, i-exhaust camshaft kanye neyunithi yokulawula injini (Bosch Motronic MV17.4.6).
Izixazululo zesakhiwo nokushiswa
Imodeli yayifakwe nesistimu ye-Valvetronic, kanye nesistimu ye-VANOS ekabili, eyayinomthwalo wemfanelo wokulawula ama-valve. Ukushiswa kwaqala ukulawulwa kusetshenziswa ama-lambda probes, nawo asebenza ngomthwalo omkhulu. Izixazululo ezishiwo ngenhla zisho ukuthi injini ye-N46 idle uphethiloli omncane futhi ikhiqize ukungcola okuncane okufana ne-CO2, i-HmCn, i-NOx ne-benzene. Injini engenaValvetronic yaziwa ngeN45 kanti ibitholakala ngezinhlobo ezingu-1,6 no-2,0 litre.
Idatha yobuchwepheshe yesikhungo samandla
Izici zedizayini zifaka ibhulokhi ye-aluminium, ukucushwa kwe-inline-four, namavalvu e-DOHC amane isilinda ngasinye ane-90mm bore kanye ne-84mm stroke.
Isilinganiso sokucindezela sasingu-10.5. Isamba sevolumu 1995 cc Iyunithi kaphethiloli idayiswe ngesistimu yokulawula i-Bosch ME 9.2 noma i-Bosch MV17.4.6.
bmw injini yokusebenza
Injini ye-N46 kwadingeka isebenzise amafutha angu-5W-30 noma angu-5W-40 futhi ayishintshe njalo nge-7 noma i-10 km eyizinkulungwane. km. Umthamo wethangi wawungamalitha angu-4.25. Kwi-BMW E90 320i, lapho le yunithi ifakwe khona, ukusetshenziswa kukaphethiloli kwakuguquguquka ngamavelu alandelayo:
- 7,4 l/100 km exutshwe;
- 5,6 l / 100 km emgwaqeni omkhulu;
- 10,7 l/100 km engadini.
Umthamo wethangi ufinyelele amalitha angama-63, futhi ukukhishwa kwe-CO02 kwaba ngu-178 g / km.
Ukuphuka kanye nokungasebenzi kahle yizinkinga ezivame kakhulu
Kube namaphutha ekwakhiweni komgwaqo u-N46 okuholele ekutheni kube khona ukungasebenzi kahle. Okunye okwakuvame kakhulu kwakuwukusetshenziswa kukawoyela okuphezulu. Kulesi sici, into esetshenzisiwe idlala indima ebalulekile - ezingcono azibangeli izinkinga. Uma lokhu kunganakekelwa, ama-valve stem seal namasongo e-piston ahluleka - ngokuvamile ngo-50 km. km.
Abasebenzisi bezimoto baphinde badonsela ukunaka ekudlidlizeni okunamandla nomsindo weyunithi. Kwakungenzeka ukuqeda le nkinga ngokuhlanza uhlelo lwesikhathi lwe-valve eguquguqukayo ye-VANOS. Imisebenzi eyinkimbinkimbi eyengeziwe yayidinga ukumiselela uchungechunge lwesikhathi, olunganwebeka (imvamisa ngemva kuka-100 km).
Ukushuna kweDrayivu - iziphakamiso zokulungiswa
Injini inamandla amaningi uma kukhulunywa ngokushuna. Kulolu daba, enye yezinketho ezivame kakhulu zabanikazi bezimoto ezinenjini ye-N46 i-chip tuning. Ngenxa yalokhu, ungakwazi ukwandisa amandla okushayela ngendlela elula. Lokhu kungenziwa kusetshenziswa i-firmware ye-ECU enolaka. Ukuthuthukiswa kuzoba ukwengezwa kokungenisa umoya obandayo, kanye nesistimu yokukhipha ikati-back. Ukushuna okwenziwe kahle kuzonyusa amandla eyunithi yamandla aze afike ku-10 hp.
Ungashuna kanjani futhi?
Enye indlela ukusebenzisa i-supercharger. Ngemva kokuxhuma i-supercharger ohlelweni lwe-injini, i-hp ingatholakala ngisho kusuka ku-200 kuya ku-230 hp. Izindaba ezinhle ukuthi awudingi ukuhlanganisa izingxenye ngazinye ngokwakho. Ungasebenzisa ikhithi eseyenziwe ngomumo evela kubakhiqizi abathembekile. Okuwukuphela kwento embi yalesi sixazululo intengo, kwesinye isikhathi ifinyelela ku-20 XNUMX. i-zloty.
Uma uqinisekile ukuthi imoto enenjini ye-N46 isesimweni esihle sobuchwepheshe, kufanele uyikhethe. Izimoto nezimoto zithola ukubuyekezwa okuhle, ziqinisekisa ubumnandi bokushayela kanye nokusebenza kahle nomnotho wokusebenza. Inzuzo iphinde ibe nethuba lokulungisa i-BMW drive.
