BMW N45B16 injini
Okuqukethwe
Isici esiyinhloko somodeli we-BMW N45B16 amandla ahlobene enjini, naphezu komthamo omncane we-cubic womklamo.
Ukubumbana nesisindo esincane senjini kwenze kwaba nokwenzeka ukujwayela injini endaweni elinganiselwe yenjini yezimoto ezincane, ukuxazulula izinkinga ezimbili ngesikhathi esisodwa: ukusebenza kahle kwesistimu yokupholisa okwanele kanye nokusabalalisa kwesisindo esilinganiselwe.
I-BMW 1-Series hatchbacks esekelwe kule njini ibithambile futhi ishesha, naphezu kokushoda kwesakhiwo somzimba.
Umlando omfushane: ukuzalwa nokuduma kwenjini edumile
Imodeli ye-BMW N45B16 yaklanywa ngesisekelo senjini ye-N45 futhi iyinguqulo ethuthukisiwe yesizukulwane sangaphambilini. Ukufakwa kwe-motor ukukhiqizwa kwe-conveyor kwakuhlelwe ekuqaleni kuka-2003, noma kunjalo, ngenxa yokwanda kokubumbana komklamo, abathuthukisi banquma ukuhlehlisa ukukhiqizwa okuphelele kuze kube ngu-2004.
Ukuthuthukiswa okude kwanikeza injini ukuthandwa okukhulu ekuqaleni kwekhulu lama-21: injini engu-4-cylinder in-line enevolumu engu-1596 mm yakhiqiza amandla afinyelela ku-85 kW, ahambisana namandla angu-115 amahhashi. Injini ibhekane kahle nomthwalo ngesivinini esiphansi futhi inyukile i-torque, ehlangene yanikeza amandla aphezulu.
Ububi obukhulu bemodeli ye-BMW N45B16 ukuncika kuphethiloli - iyunithi yamandla isebenza kuphela kuphethiloli we-octane ephezulu. Ukusetshenziswa kukaphethiloli ngaphansi kwesigaba A95 kuholela ekushaqekeni okunamandla kwe-detonation, okuthinta kabi impilo yokusebenza kwesakhiwo. Amamodeli amaningi ochungechungeni ahlulekile ngenxa yokukhiywa kwepiston noma ukulimala kwamavalvu - ukuphuka okuvele ngenxa yekhwalithi yezinga eliphansi ngesivinini esiphezulu senjini.
I-BMW N45B16 ifakwe kuphela esizukulwaneni sokuqala se-E81 ne-E87 hatchbacks ngenxa yevolumu yabo ehlangene - ezinye izimoto azizange zifakwe lezi zinjini ezivela embonini.
Kuyathakazelisa lokhu! Kusukela ngo-2006, abakhiqizi baye baqinisa ukuklama kwe-BMW N45B16, ukwandisa amandla enjini nokwandisa umthamo wamagumbi okusebenza ku-2 amalitha, izithombe zesizukulwane esilandelayo semodeli - N45B20S. Inguqulo entsha bekuwumhlangano wezemidlalo futhi yakhiqizwa ngohlelo olulinganiselwe ochungechungeni lwe-BMW 1 lokucushwa okuphezulu.
Технические характеристики
Isici esihlukile sale motor kusuka kumanduleli wayo i-N42B18 kwaba ukuncishiswa kwe-crankshaft, ehlinzeka ngokushaywa kwe-piston emfushane, kanye nokufakwa kwezinguqulo ezithuthukisiwe zesistimu ye-piston kanye nezinduku zokuxhuma. Inhloko ye-cylinder yenjini ithole ikhava eguquliwe, futhi ukuthuthukiswa komklamo weyunithi yamandla ekuqondeni kwe-torque ekhulayo kuphoqelele ukufakwa kwamakhandlela amasha kanye ne-generator.

Inombolo ye-VIN yenjini itholakala ngaphambili kweyunithi yamandla phakathi nendawo yedivayisi. Futhi, lapho uthenga injini embonini, umaka wensimbi unamathiselwe kukhava ephezulu ngedatha ngosuku lokukhiqiza kanye nomkhiqizi.
Injini isebenzisa uphethiloli we-A95 kuya phezulu, idla amalitha angu-8.8 edolobheni kanti isuka ku-4.9 emgwaqeni omkhulu. Amafutha asetshenziswa i-brand 5W-30 noma i-5W-40, ukusetshenziswa okuphakathi kwe-1000 km ngamagremu angu-700. Uketshezi lobuchwepheshe lushintshwa njalo ngamakhilomitha angu-10000 2 noma njalo ngemva kweminyaka emi-XNUMX yokusebenza.
Kubalulekile ukwazi! Isakhiwo sonke senjini senziwa nge-aluminium, enganciphisanga isisindo senjini kuphela, kodwa futhi yanciphisa impilo yokusebenza - amasilinda e-aluminium awazange afinyelele ku-200 km wokugijima kusethi yefektri.
Ubuthakathaka: okudingeka ukwazi
Isizukulwane se-BMW N45B16 sihlukaniswa ngomklamo onekhono wesakhiwo, onciphise amathuba okuphuka abe okungenani. Lawa mamodeli enjini aphila ngokuthula ngokuvumelana nensiza yamaphasiphothi, okwathi ngemva kwalokho adinga ukulungiswa okuphelele: kusukela ekushintsheni ama-valve namasilinda ezindlu kuya ekufakeni ama-crankshaft amasha. Kuze kube sekupheleni kokuphila kokusebenza, abanikazi bemoto bangaphazanyiswa kuphela:
- Imisindo engaphandle enjinini - ukungasebenzi kahle kuhlanganisa ukwelula iketango noma ukukhubaza i-tensioner yesikhathi. Inkinga ivela njalo ngamakhilomitha ayikhulu - kuzodingeka ushintshe amaketanga okungenani kabili;
- Ukulayisha ukudlidliza okweqile - ukudlidliza okukhulu kubonwa ngokungenzi lutho, okuchazwa izici zokuklama zohlelo lweVanos. Isimo silungiswa ngokuhlanzwa njalo kwezingxenye kanye nokusetshenziswa kwephethiloli yekhwalithi ephezulu;
- Ukushisa ngokweqile nokuqhunyiswa - ukwehluleka kwenjini kungenzeka ngisho nalapho usebenzisa i-analogue kawoyela enconywe umenzi. Ukuze uvimbele ukulungiswa kwenjini okumba eqolo ngekhwalithi yoketshezi lobuchwepheshe, akunconywa ukulondoloza.
Ukushintshwa okuvamile kwezingxenye kanye nokuxilongwa ngesikhathi kuzogcina i-BMW N45B16 isesimweni sokusebenza kuze kube sekupheleni kwensiza. Ngokusetshenziswa ngokucophelela, le moto izojabulisa ngokuthembeka nokuthembeka.
isiphetho
Le yunithi yamandla iyisinqumo esingcono kakhulu phakathi kwentengo nekhwalithi yokukhiqiza - umhlangano wesabelomali ngokwezindinganiso zaseJalimane uqinisekisile ukuthandwa okuphezulu kwemoto kuze kube manje. Ukusetshenziswa kukaphethiloli okuphansi, ukulungiswa okuphezulu kanye nokunyuka kwe-traction kuyi-investimenti enhle: imoto esekelwe ku-BMW N45B16 izojabulisa umnikazi isikhathi esingaphezu konyaka, kodwa ukuthola izingxenye ezifanele kuzoba yinkinga kakhulu.
Ukunakwa okukhethekile kufanele kukhokhwe ekutheni kungenzeka ukushuna. Injini ye-BMW N45B16 ayimelani nokucolisiswa kwe-artisan - okokusebenza kwe-elekthronikhi ekhanyayo nokushintsha amasistimu e-exhaust ngokuhlukile kohlobo lwezemidlalo kuzokhuphula amandla okuba namandla amahhashi angu-10. Ukuthuthukiswa okusele kuzoholela kuphela ekwehleni kwensiza yokusebenza.
