BMW E39 - izinjini efakwe yisakhiwo sodumo 5-uchungechunge imoto

Umkhiqizi waseJalimane ushiye amakhasimende ngokukhethwa okukhulu kwama-powertrains atholakala ku-E39. Izinjini zakhiqizwa uphethiloli kanye diesel izinguqulo, futhi phakathi kwaleli qembu elikhulu kunezimo eziningana ezibhekwa yisakhiwo sodumo. Sethula ulwazi olubaluleke kakhulu mayelana nezinjini ezifakwe ku-BMW 5 Series, kanye nezindaba mayelana namayunithi abhekwa njengempumelelo kakhulu!

E39 - izinjini zikaphethiloli

Ekuqaleni kokukhiqizwa kwemoto, i-M52 inline six yafakwa, kanye ne-BMW M52 V8. Ngo-1998, kwenziwa isinqumo sokuthuthukisa ubuchwepheshe. Lokhu kufaka phakathi ukwethulwa kwesistimu ye-VANOS ephindwe kabili kokuhluka kwe-M52 kanye nesistimu eyodwa ye-VANOS kumodeli ye-M62. Ngakho-ke, ukusebenza okuhlobene ne-Nm nge-rpm ephansi kuye kwathuthukiswa.

Izinguquko ezilandelayo zenzeka ngemva kweminyaka emibili. Uchungechunge lwe-M52 lwathathelwa indawo iBMW M54 enemigqa engu-6, kwathi i-M62 yahlala kumamodeli e-V8. Idrayivu entsha ithole ukubuyekezwa okuhle kakhulu futhi ngo-10 no-2002 yafakwa kumamotho ayishumi ahamba phambili emhlabeni ngokusho kwephephabhuku i-Ward. Kumodeli ka-2003i, injini ye-M54B30 yafakwa.

E39 - izinjini diesel

Izimoto ezinenjini yedizili zazifakwe injini yedizili ene-turbocharged ene-spark ignition - imodeli M51 inline 6. Ngo-1998 yashintshwa i-M57 yafakwa ku-BMW 530d. Lokhu akusho ukuphela kokusetshenziswa kwayo - yasetshenziswa ku-525td naku-525td iminyaka eminingana.

Ushintsho olulandelayo lweza ngokufika kuka-1999. Ngakho kwaba imodeli BMW 520d - M47 ezine-cylinder turbodiesel. Kuyaphawuleka ukuthi lokhu kwakuwukuphela kwe-E39 okuhlukile lapho iyunithi enezici ezinjalo zafakwa.

Okungcono kakhulu ukukhetha - amayunithi kaphethiloli azibonakalise kakhulu

Izimoto ze-E39 zazibonakala ngesisindo somgwaqo esikhulu. Ngenxa yalesi sizathu, injini engu-2,8 litre ene-190 hp, kanye nenguqulo ethuthukisiwe ye-3-litre ene-231 hp, yayibhekwa njengenhlanganisela efanele yamandla nezindleko zokusebenza eziphansi. - M52 kanye ne-M54. 

Abasebenzisi bezimoto baqaphele ukuthi, phakathi kwezinye izinto, ukusetshenziswa kukaphethiloli kwazo zonke izinhlobo zemigqa engu-6 kuyefana, ngakho ukuthenga inguqulo engu-2-litre yeyunithi yamandla ye-BMW E39 akuzange kube nengqondo. Inguqulo ye-2,5-litre elungiswe kahle yayibhekwa njengesixazululo esingcono. Okuhlukile ngakunye kube nalezi zindlela ezilandelayo: 2,0L 520i, 2,5L 523i kanye no-2,8L 528i.

Yiziphi izinhlobo zikadizili okufanele uzinake?

Kumayunithi edizili, okuhlukile kwe-M51S kanye ne-M51TUS enamaphampu kaphethiloli anengcindezi ephezulu bekuyisinqumo esihle. Babethembekile kakhulu. Izingxenye ezibalulekile ezifana nochungechunge lwesikhathi kanye ne-turbocharger zisebenze ngendlela enokwethenjelwa ngisho nebanga elilinganiselwa ku-200 km. km. Ngemva kokunqoba leli banga, umcimbi wesevisi obiza kakhulu kwakuwukulungiswa kwepompo yomjovo.

Injini yesimanje diesel M57

Izinjini zesimanje nazo zike zavela ohlotsheni lweBMW. Ibizwa kanjalo izinjini ngomjovo kaphethiloli oqondile. Odizili beTurbo abanohlelo lweCommon Rail baqokwe i-525d ne-530d kanti umthamo wabo wokusebenza ubungu-2,5 litres no-3,0 litres, ngokulandelana. 

Imodeli yenjini yamukelwa kahle futhi yaphawulwa njengezinga eliphakeme lokuthembeka uma iqhathaniswa ne-M51 - kuyaphawuleka ukuthi lokhu kwakuhlobene ngokuqondile nokusetshenziswa kwamafutha aphezulu, lapho isimo sobuchwepheshe senjini sincike khona. 

Isistimu yokupholisa enephutha

Kunezinkinga eziningana ezivamile eziphakama lapho usebenzisa amayunithi okushayela adumile. Ukwehluleka okuvamile kwakuhlobene nesistimu yokupholisa. 

Ukwehluleka kwayo kungase kubangelwe ukungasebenzi kahle kwe-fan motor eyisizayo, i-thermostat, noma irediyetha evalekile kanye nezinguquko zoketshezi ezingavamile kule nhlangano. Isixazululo singase kube ukubuyisela yonke isistimu njalo eminyakeni emi-5-6 ngoba lokho kuyisilinganiso sempilo yabo. 

Amakhoyili okushisa ezimo eziphuthumayo kanye nama-electronics

Kulokhu, izinkinga zingaqala lapho umsebenzisi eyeka ukusebenzisa ama-spark plug angewona awoqobo. Izingxenye ezisele ezinophawu ngokuvamile zanele 30-40 ayizinkulungwane km. km. 

Izinjini ze-E39 nazo zazinezici eziningi zokuklama zikagesi. Ukukhubazeka kungase kuhlotshaniswe nama-lambda probes alimele, abemaningi afinyelela kwangu-4 kumamotho aginqiwe. Kuphinde kwaphuka i-air flow meter, i-crankshaft position sensor kanye ne-camshaft.

Tuning drives efakwe ku-E39

Inzuzo enkulu yezinjini ze-E39 kwaba ukuguquguquka kwazo kokushuna. Enye yezinketho ezaziwa kakhulu kwakuwukucwenga amandla enjini ngesistimu yokukhipha umoya ngaphandle kweziguquli ze-catalytic ezine-4-2-1 manifolds, kanye nokungena komoya obandayo nokushuna kwe-chip. 

Kumamodeli afiselekayo ngokwemvelo, i-compressor yayiyisixazululo esihle. Enye yezinzuzo zalo mbono kwaba ukutholakala okuphezulu kwezingxenye ezisele ezivela kubakhiqizi abathembekile. Ngemva kokusetha injini esitokisini, amandla eyunithi yamandla kanye ne-torque anda. 

Ingabe akhona amamodeli enjini okufanele uwanake?

Ngeshwa, akuwona wonke amamodeli ezithuthuthu aphumelele. Lokhu kusebenza kumayunithi kaphethiloli asebenzisa i-nickel-silicon cylinder coating.

Isendlalelo se-nikasil sibhujisiwe futhi yonke ibhulokhi idinga ukushintshwa. Leli qembu lihlanganisa izinjini ezakhiwe ngo-September 1998, okwathi ngemva kwalokho i-BMW yanquma ukushintsha i-Nikasil ngongqimba lwe-Alusil, oluqinisekisa ukuqina okukhulu. 

I-BMW E39 - injini esetshenzisiwe. Yini okufanele uyibheke lapho uthenga?

Ngenxa yokuthi sekudlule iminyaka eminingi kusukela ngesikhathi sokukhiqiza, kuyadingeka ukunaka ngokukhethekile isimo sobuchwepheshe sedrayivu ethengiwe. Ekuqaleni, kufanelekile ukuhlola ukuthi i-block yenziwe nge-nikasil. 

Isinyathelo esilandelayo ukuhlola isimo se-heatsink kanye ne-fan cut-off coupling eshisayo. I-thermostat ne-air conditioner radiator fan kumele nayo ibe sesimweni esihle. Injini ye-BMW E39 esesimweni esifanele ngeke ishise futhi izokunikeza injabulo enkulu yokushayela.
