Injini ye-N46B20 - ukucaciswa, ukuguqulwa nokulungisa iyunithi yamandla evela kwaBMW!

Injini ye-N46B20 yathuthukiswa ukuze ihlangabezane nezidingo zezimakethe lapho intela yokususa isilinda yethulwe khona. Idizayini yayo yathuthukiswa ngokuhambisana nokuhluka kwe-N42. Ngakho-ke ukufana okuningi. ebukhulu be-cylinder bore noma ama-piston kanye ne-crankcase esetshenzisiwe. Imininingwane ebaluleke kakhulu nge-N46B20 isilapha!

Injini ye-N46B20 - idatha yobuchwepheshe

Injini ye-N46B20 yakhiqizwa kusukela ngo-2004 kuya ku-2012 efektri yakwaBMW Hams Hall eBavaria. Iyunithi kaphethiloli ejovwe ngophethiloli isuselwe ekwakhiweni lapho wonke amasilinda amane anamapiston amane nelilodwa (DOHC) aqondaniswe ngokulandelana.

Ububanzi be-cylinder yenjini buyi-84 mm, kanti i-piston stroke ifinyelela ku-90 mm. I-oda lokudubula ngu-1-3-4-2. Usayizi wenjini oqondile ngu-1995 cc. cm, futhi isilinganiso sokucindezela singu-10.5. Imodeli ihambisana nezindinganiso zokukhishwa kwe-Euro 4-5.

Izinguqulo ezahlukahlukene zeyunithi yamandla ye-N46B20

Kusukela ngo-2004 kuya ku-2012, kwadalwa izinhlobo eziningana zamayunithi amandla. Abazange bahluke emandleni kuphela, kodwa futhi nasezixazululweni zokuklama. Leli qembu lihlanganisa izinhlobo ezifana nalezi:

• I-N46B20U1 kanye ne-N46B20U2 129 hp ku-180 Nm (2004-2007);
• I-N46B20U2 136 HP ku-180 Nm (2004-2007): inguqulo ine-multitake manifold ehlukile (hhayi i-DISA) kanye ne-exhaust camshaft ehlukile;
• I-N46B20O0 143 HP ku-200 Nm (2004-2007);
• I-N46B20O1 150 HP ku-200 Nm (2004-2007);
• I-N46NB20 170 HP ku-210 Nm (2007-2012): Ngokuklanywa okufanayo nenguqulo engu-150 hp, kodwa ngekhava yekhanda yesilinda entsha kanye nesistimu yokukhipha umoya. Isistimu yokulawula ye-Bosch MV17.4.6 yengezwe kuyo.

Yiziphi izinhlobo zezimoto ezisebenzisa injini futhi uwoyela kufanele ushintshwe kangaki?

Injini engu-N46B20 ifakwe ezimotweni ezifana ne-BMW 118i E87, BMW 120i E87, BMW 318i E46, BMW 318i E90, BMW 320i E90, BMW 520i E60, BMW X1 E84 X3 E83, BMW X4 E85 EXNUMX, BMW XNUMX EXNUMX

Ukusebenza kwenjini ye-BMW kudinga ukusetshenziswa kukawoyela 5W-30 noma 5W-40 - kufanele kushintshwe njalo 10-12 km. km noma izinyanga eziyi-XNUMX. Umthamo wethangi lalo mkhiqizo ungamalitha angu-4,25. 

Ukusebenzisa iyunithi yokushayela - izinkinga ezivame kakhulu nokuthi ungazixazulula kanjani

Injini ye-N46B20 ibhekwa njengeyunithi yokwehluleka okuphansi. Ngokusebenza kahle, ukugcinwa nokuhlolwa okuvamile, injini ayibangeli izinkinga ezinkulu.

Kodwa-ke, kukhona ukwehluleka okuhlotshaniswa ne-mileage ephezulu noma ukusebenza kwemvelo kwama-node ngamanye. Kuyafaneleka ukuthola ukuthi yimuphi kubo ovela kaningi.

Injini ingase idle uwoyela omningi kakhulu

Inkinga yokuqala eyenzeka kaningi ukusetshenziswa kukawoyela ngokweqile. Imvamisa isizathu siwukusetshenziswa kwento esezingeni eliphansi - engaphawulwanga ngabakwaBMW njengamafutha anconyiwe. Ama-valve stem seal awonakele, bese kuba amasongo e-piston. Lokhu kubonakala kakhulu ekugijimeni okungaba ngu-50 km. km.

Izinto ezizoqala ukuvuza ngemva kokugijima inombolo eshiwo yamakhilomitha futhi zihlanganisa i-valve cover gasket noma i-vacuum pump eyonakele. Ezimweni ezinjalo, kuyadingeka ukufaka esikhundleni sezingxenye.

Ukudlidliza nomsindo kunciphisa ukunethezeka kokushayela

Ezimweni eziningi, ukudlidliza nakho kuzwakala kakhulu. Okwamanje lapho iyunithi ye-2.0-litre iqala ukuzwakala kakhulu, kufanelekile ukucabangela ukuhlanzwa okuphelele kwesistimu yesikhathi ye-Vanos variable valve.

Akukhona nje kuphela ukuthi ukudlidliza okuphazamisa ukusebenza kahle kweyunithi yokushayela. Injini ingase futhi yenze umsindo omkhulu kakhulu. Lokhu ngokuvamile kungenxa ye-tensioner ye-timing chain enephutha noma uma le elementi yeluliwe. Le nkinga yenzeka ngemuva kwebanga lika-100 XNUMX km. km. Izingxenye zizodinga ukushintshwa.

Injini engu-N46B20 ilungele ukushuna

Indlela yokuqala enhle yokwandisa amandla edrayivu yakho kungaba isofthiwe ye-ECU. Isistimu yokukhipha umoya obandayo kanye ne-exhaust nayo ingasetshenziswa ukwandisa ukusebenza kahle. Ngakho-ke, injini izokhiqiza cishe i-10 hp. amandla engeziwe.

Isixazululo sesibili i-boost kit - i-turbocharger. Lokhu kungaba enye indlela enhle kune-firmware eshiwo ngaphambilini. Ukufakwa okukhethiwe kahle kuzokwandisa amandla enjini ngisho nasezingeni lika-200-230 hp. Iphakheji ingakhiwa ibe yiyunithi yokushayela yangempela. Isithiyo kungase kube intengo - esimweni se-N46 Turbo Kit, kubiza cishe i-PLN 20. i-zloty. 

Ingabe injini ye-N46B20 iyunithi enhle?

Ezongena esikhundleni se-N42 ibaluleke kakhulu ngokwakhiwa kwayo okuqinile, amandla okushayela okuhle, kanye nesiko lokushayela elisezingeni eliphezulu kanye nokuba khona okuphezulu kwezinsimbi eziyisipele. Ububi buhlanganisa ukusetshenziswa kukawoyela okukhulu, kanye nokuhluleka kwesistimu kagesi. Kufanele futhi kukhulunywe ukuthi kungenzeka ukufaka uhlelo lwe-LPG.

Injini engu-N46B20 ingathengwa ezimotweni ezisenomklamo okhangayo futhi obukeka esimanjemanje. Izimoto zakwaBMW ezinale njini kufanele ziqale zibhekwe ukuthi zisebenza kanjani. Iyunithi ye-N46B20 esebenzisekayo izohamba izinkulungwane zamakhilomitha ngaphandle kwezinkinga.
