BMW N73B60, N74B60, N74B66 izinjini

Izinjini ze-BMW N73B60, N74B60, N74B66 ziyimodeli ethuthukisiwe yezinjini ezidumile zeBMW 7 Series ngemuva kwe-E65, E66, E67 ne-E68, kanye neRolls-Royce.

Injini ngayinye iyisizukulwane esilandelayo semodeli endala: zonke izinjini zisebenza ngesimiso esifanayo futhi zinezici zobuchwepheshe ezilinganiselwe, ezihluke kuphela ekuklanyweni okucatshangelwe kahle.

Ukuthuthukiswa nokukhiqizwa kwezinjini ze-BMW N73B60, N74B60, N74B66: bekunjani?

Ukukhiqizwa kwezinjini zochungechunge oluningi kwakuhambisana nokukhiqizwa kochungechunge lwe-BMW lwe-7. Ukuthuthukiswa kochungechunge lokuqala lwe-BMW N73B60 kwaqala ekuqaleni kuka-2000, futhi injini ngokwayo yangena emgqeni womhlangano kusukela ngo-2004 futhi yakhiqizwa kuze kube ngu-2009, okwathi ngemva kwalokho yathathelwa indawo yisizukulwane esilandelayo N74B60 kanye ne-N74B66.

Njengamanje, ukukhiqizwa kwezinjini kuyaqhubeka futhi emakethe yezimoto yesibili ungathola ngokukhululekile izingxenye zangempela kanye nama-analogue wezingxenye ezisele. Naphezu kwamandla aphezulu, injini ifakwe izingxenye zomthengisi we-replica ezingafinyezi impilo yesevisi noma amandla - amamodeli e-BMW N73B60, N74B60, N74B66 ayitshalomali elihle kubathandi bamandla.

Kuyathakazelisa lokhu! Injini ngayinye ochungechungeni yathuthukiswa ngokuya ngephrojekthi yayo, noma kunjalo, izingxenye zesizukulwane esedlule zazisetshenziselwa ukukhiqizwa. Lesi sinyathelo senza kube nokwenzeka ukuhlanganisa ukuklama, ukwenza lula isiteji sokukhiqiza nokuqeda bonke ubuthakathaka bamamodeli amadala.

Imininingwane: yini efanayo kumamodeli

Lonke uchungechunge lwenjini iyinjini engu-12-cylinder eklanywe ngesakhiwo esimise okwe-V. Zonke izingxenye zenziwe nge-aluminium, futhi izingxenye zomzimba kanye ne-CPG zihambisana nanoma yisiphi isizukulwane senjini, okwandisa ukulungiswa nokunciphisa izindleko zokukhiqiza izingxenye. Futhi, kusukela izici ezivamile BMW N73B60, N74B60, N74B66 izinjini, kufanele kuqashelwe:

• Uhlelo lokujova uphethiloli olunembe kakhulu;
• Uhlelo oluzimele lwezakhi ze-piezoelectric ezihlinzeka ngokuthungela;
• Ipheya lezifudumezi zomoya ezisebenza ngokomgomo wokungaqondile ngokuphephetha ngokupholisa okungaqondile;
• Isistimu ye-vacuum enepompo ye-vacuum enezigaba ezimbili;
• Isistimu ye-VANOS ephindwe kabili.

Isizukulwane ngasinye salolu chungechunge sasifakwe uwoyela ohlukile kanye nesistimu yokungenisa umoya ye-crankcase, futhi yayinomklamo othuthukisiwe we-camshaft kanye ne-roller chain design. Futhi, wonke ulayini wezinto ze-elekthronikhi ezibhekele ukufana kokuphakelwa kukaphethiloli kanye nemvamisa yokuthungela ube ngaphansi kokucwengwa.

Injini ngayinye yayinokudluliselwa kwayo okuzenzakalelayo, noma kunjalo, emazingeni okunciphisa isabelomali amaJalimane, uchungechunge lwe-7 lufakwe i-ZF 8HP evamile. Inombolo ye-VIN yenjini yefekthri yagxivizwa phezu kwekhava yenjini phakathi kwama-air charger.

Ubuthakathaka bochungechunge: ungalindela kuphi ukuphazamiseka

Ukukhiqizwa kusukela ekuqaleni kwenjini ngayinye kwenze kwaba nokwenzeka ukunciphisa inani lobuthakathaka emiklamo yemoto ngayinye, noma kunjalo, naphezu kokucabangela kwezakhiwo zobuchwepheshe, izikhala zembulwa kuma-motors ngesikhathi sokusebenza okujulile. Okubi okubalulekile kwe-BMW N73B60, N74B60, N74B66 okubonwe ngaphambi kwesisetshenziswa esiqinisekisiwe kube:

• Isivinini esintantayo esiyize - ngenxa yezinto ezingavamile zokusebenza kwesistimu ye-Valvetronic, lapho injini ifinyelela izinga lokushisa elisebenzayo lingenzi lutho, umthwalo wokudlidliza wanda, okwaholela ekushaqekeni okunamandla okuphazamisa ukunikezwa kukaphethiloli ozinzile. Lokhu kungasebenzi kuyisici sefekthri futhi kwaqedwa kuphela ngokukhiqizwa kwesakhiwo esisha seyunithi;
• Idizayini yesikhathi esiyinkimbinkimbi - ibhande lemoto lingenwa yimiphumela ephezulu yokushisa, edinga ukunakekelwa okuvamile. Kunconywa ukuthi ushintshe izingxenye zeyunithi yesikhathi njalo ngamakhilomitha angama-80-100 wokugijima;
• I-motor decompression - isimo sibangelwa ukwephulwa kokuqina kwepheshana lokungena, elilungiswa ngokushintshwa okufika ngesikhathi kwama-o-rings kanye ne-sealant;
• Ukwehluleka kwe-cylinder block - lonke uhlelo lwenjini lusebenza ngesisekelo samayunithi amabili okulawula, futhi uma elinye lawo liphuka, inani lamasilinda livaliwe.

Idizayini yezinjini ze-BMW N73B60, N74B60, N74B66 ibonakala ngezingxenye eziningi ezihambayo ezandisa izinga lokushisa eliphelele lenjini. Ukuze ugweme ukushisa okweqile kwenjini, kunconywa ukuthi ushintshe ngokuphelele i-coolant njalo eminyakeni emi-2 ngokushintsha okuphoqelekile kwesistimu.

Amathuba wokushuna

Ngenxa yesisekelo sesakhiwo esiyinkimbinkimbi, ukuphazamiseka kwangaphandle kwezingxenye zenjini akuvunyelwe ngumkhiqizi - izinto eziningi eziguquliwe zithinta kabi impilo yokusebenza kwenjini futhi zidale ukulungiswa okubizayo.

Isinyathelo esiphusile sokwandisa ukusebenza kwenjini ukushuna kwe-chip kuphela: okokusebenza kukagesi okuphazimayo kukuvumela ukuthi uzinzise ukunikezwa kukaphethiloli ngokumisa injini ijubane elikhulu noma ukudonsa. I-firmware ye-elekthronikhi ikuvumela ukuthi ukhuphule amandla enjini abe namandla angama-609 ngaphandle kokulahlekelwa yimpilo yokusebenza - ngisho nenjini efakwe nezichibiyelo ekusebenzeni igijima amakhilomitha angama-400 ngaphandle kwesidingo sokulungiswa okukhulu.

Kafushane ngento esemqoka

Ibanga lamamodeli ochungechunge lwe-BMW 7 BMW N73B60, N74B60, N74B66 liwumfanekiso womklamo onokwethenjelwa namandla aphezulu. Izinjini zinamandla futhi ziqinile, kodwa zidinga ukulungiswa njalo.

Uchungechunge lwe-V12 lwe-turbocharged lufanele abalandeli bezimoto ezinamandla abangenandaba nezindleko zokulungiswa kanye nentengo yezingxenye, futhi izinjini azifanele ukusetshenziswa kwansuku zonke.
