Lokhu, okokuqala, ukuqina okungavamile kanye nesikhathi esingenakulungiswa. Naphezu kokuthi i-torque ezinguqulweni ezibuthakathaka yayisezingeni lika-390-410 Nm, imoto yayiphatha kahle kakhulu. Isistimu yonke ye-crank-piston, i-gearbox nezinye izinto zokuhambisa zifaniswe kahle namandla akhiqizwa yile yunithi. Akukhathalekile ukuthi uchungechunge lwesithathu (isibonelo, i-E3, i-E46) noma uchungechunge lwesi-90 (isibonelo, i-E5 ne-E39) - kumshini ngamunye wale mishini, lo mklamo unikeze ukusebenza okuhle kakhulu. Eminyakeni yokuqala yokukhiqiza, asikho isihlungi se-DPF esafakwa ohlelweni lwe-exhaust, okuthi ngokuhamba kwesikhathi kubangele ukungasebenzi kahle.
Injini engu-M57 eku-BMW 3.0d namandla ayo okushuna
Ama-Power buffs akhomba ukuthi izinguqulo ze-330d ne-530d ziyizimoto ezilungele ukushuna. Isizathu ukuqina okuphezulu kakhulu kwesistimu yokudlulisa idrayivu kanye nokuzwela okuphezulu ekushintsheni kwesilawuli semoto. Ungakwazi ukukhipha kalula amandla angaphezu kuka-215 enguqulweni ebuthaka ngohlelo olulodwa nje. I-Common Rail system kanye nama-turbocharger angamawele ayisisekelo esihle sokusebenza okwengeziwe. I-400 hp, ikalwa nge-dyno ngaphandle kokungenelela okuningi ezindongeni zokuxhuma nama-piston, ngokuyisisekelo kuwumkhuba wamashuna.

Akunzima ukuqagela ukuthi ucezu lwesici oluwele ekamelweni lomlilo lungabangela umonakalo omkhulu kuma-valve, ama-piston kanye nama-cylinder liners. Ezinguqulweni ezintsha (kusukela ngo-2007), le minyango yathathelwa indawo emikhudlwana engazange iphuke, kodwa ayizange ihlale iqinile. Ngakho indlela engcono kakhulu ukuwaqeda.
Ezinye izingqinamba ze-armored diesel 3.0d
Kunzima ukulindela ukuthi injini ye-M57, osekuyiminyaka eminingi itholakala emakethe yesibili, ngeke iphuke. Ngaphansi kwethonya leminyaka eminingi yokusebenza, umjovo noma eziningana ngezinye izikhathi zehlulekile. Ukuvuselelwa kwabo akubizi kakhulu, okuhumushela ekunakekeleni okungenazinkinga nokushesha. Abanye abasebenzisi bakhombisa ukuthi ama-thermostat angaba inkinga ngokuhamba kwesikhathi. Isikhathi sabo esiphezulu ngokuvamile siyiminyaka emi-5, ngemva kwalokho kufanele bashintshwe. Okubalulekile, ngisho nesihlungi se-DPF asinayo inkinga njengezinye izimoto. Yiqiniso, kufanelekile ukukhumbula imithetho eyisisekelo yokuyishisa.
Izindleko zokusevisa imoto enenjini engu-M57
Ingabe uhlela ukuthenga inguqulo engu-184 hp, i-193 hp noma 204 hp - izindleko zokusebenza akufanele zikwesabise. Emgwaqeni i-3 litre idla amalitha angu-6,5/100 km. Edolobheni elinesitayela sokushayela esiguqukayo, leli nani lingaphinda kabili. Yebo, uma iyunithi inamandla kakhulu futhi isisindo semoto, kuyanda ukusetshenziswa kukaphethiloli. Kodwa-ke, isilinganiso sokusetshenziswa kukaphethiloli kuya ku-dynamics kanye nokuzijabulisa kokushayela kuhle kakhulu. Khumbula ukushintsha uwoyela njalo njalo emuva kuka-15 000 km kanye nemithetho eyisisekelo yokushayela udizili, futhi izokusebenzela iminyaka eminingi. Izingxenye ezisebenzisekayo ziseshalofini lentengo elijwayelekile - vele, sikhuluma ngezinga le-BMW.
Ingabe kufanelekile ukuthenga i-BMW enenjini engu-M57?
Uma unethuba lokuthenga ikhophi egcinwe kahle enomlando oqinisekisiwe, ungangabazi isikhathi eside. I-BMW enale njini iyikhethelo elihle kakhulu, ngisho noma ibanga lika-400 000 km.
