Isebenza kanjani iBMW 50d tri-turbo diesel engine?
Uma amasistimu ama-twin-turbo eyinhlanganisela eyaziwa ngokuthi ukulandelana noma ukuhambisana, kufanele kuqashelwe uhlangothi lobuchwepheshe lwe-tri-turbo ye-BMW, oluhlanganisa kancane lobu buchwepheshe obubili. Sicela uqaphele, uma ungenalo ulwazi mayelana nama-turbocharger, ngikumema ukuthi ubheke lapha.
Isebenza kanjani le njini ye-turbo emithathu?
Okokuqala, kufanele kuqashelwe ukuthi lolu hlelo lokushaja okuphezulu luqukethe amaturbine amabili amancane (1 no-3 kumdwebo) anejiyomethri eguquguqukayo, kanye ne-turbocharger enkulu evamile (2 emdwebeni). Ngayinye yalezi zakamuva icupha izivinini ezithile, bese zitholwa ngokungaguquguquki ezimodini eziphakeme (kahle, uma ungabiza lokho ngesivinini esikhulu, ngoba udizili awukaze uhambe kakhulu ...).
Kuma-revs aphansi, ngaphansi kuka-1500 rpm, i-turbo yokuqala (eyodwa yama-geometry amabili amancane aguquguqukayo) icelwa i-exhaust (umoya ohlanzekile ongena uvela ngaphandle usadlula ku-turbo enkulu). Noma ingakasebenzi kuleli banga lejubane). Khona-ke, kusukela ku-1500 rpm, omkhulu uyakhahlela futhi, ngoba ukugeleza kwe-exhaust manje kwanele ukukunonga. Khumbula ukuthi ama-turbines amathathu awasebenzi ndawonye kusukela ekuqaleni kwemodi, ngoba kulokhu ukuphefumula akubalulekile ngokwanele emsebenzini wama-compressor amathathu. Ekugcineni, ngo-2500 rpm, eyesithathu ekugcineni ingaqala ukusebenza ngenxa yokuvulwa kwe-damper (ebizwa ngokuthi i-bypass), evumela ukuthi igesi yokukhipha umoya inikezwe kule turbocharger (ngoba ngikukhumbuza ukuthi amandla akuvumela ukuthi ushayele. injini). I-turbo "umoya" okhiqizwa amagesi aphumayo).
Ngokombono wezokwakha, singacabanga ngamaturbines 1 kanye no-2 njengasochungechungeni ngokuhloniphana, kuyilapho izinjini zomoya 1 kanye no-3 (ezimbili ezincane) zihambisana.
Ekuqaleni, ukugeleza kwegesi ephumayo kumaphakathi, ngakho-ke i-turbine encane ithatha isigaba sokuqala sokukhuphuka.
Kakade ku-1500 rpm, injini ithuthukisa i-torque engu-650 Nm!
Injini ithuthukisa i-740 Nm (!) kusuka ku-2000 kuya ku-3000 rpm, emangalisayo uma iqhathaniswa ne-("kuphela") 381 hp ekhiqizwa.
Nali i-animation ye-BMW esemthethweni echaza ukuthi isebenza kanjani:

Ukuthembeka?
Ukubuyekezwa kwale njini eyaziwa kancane kakhulu kungaba yingcosana. Nokho, into eyodwa ukuthi injini eshisekelayo ngokwemvelo iyohlale ithembeke kakhulu kunenjini ene-turbocharged, ikakhulukazi uma kukhona ezintathu!
Amashidi e-BMW
Yonke imibono nokuphendula

(Okuthunyelwe kwakho kuzobonakala ngaphansi kwamazwana ngemuva kokuqinisekiswa)
