I-BMW 750d xDrive entsha yimodeli yophawu lwaseBavaria eneyona injini yedizili inamandla eyakha yakho.
Kumacandelo asezantsi, iinjini ze-Diesel ziye zalahlekelwa yintetho. Yibeke ityala kwimithetho engqongqo yokusingqongileyo, eye yenza ukuba iinjini zedizili zibize kakhulu ukuvelisa. Kwaye ngokuqinisekileyo, ukufaneleka kweenjini ezintsha zepetroli.Kwicandelo lobunewunewu le ngxaki ayikho, ngenxa yokuba iindleko zemveliso aziyongxaki. Abathengi bazimisele ukuhlawula nantoni na efunekayo ukuze babe nento abayifunayo.
AKUMELE UPHOSWE: Zonke iindaba (ukusuka ku-A ukuya ku-Z) kwi-2017 Geneva Motor Show
Nokuba yi-diesel ephezulu! Njengoko kunjalo nge-BMW 750d xDrive entsha, isaluni yodidi oluphezulu enobunzima obungaphezulu kweetoni ezimbini exhotyiswe ngenjini yedizili eyi-3.0 litre enee-turbos ezine ezifakwe ngokulandelelanayo. Isiphumo esisebenzayo sesi:
Njengoko ubona, i-750d entsha yi-locomotive yedizili yokwenyani, ekwaziyo ukukhawulezisa ukusuka ku-0-100 km/h ngemizuzwana eyi-4.6 kwaye ukusuka ku-0 ukuya kuma-200 km/h ngemizuzwana eyi-16.8 kuphela. Ukusetyenziswa okupapashiweyo (umjikelezo we-NEDC) ngu-5.7 l / 100km - ekugqibeleni kunye nesikhonkwane esijike phezulu phezulu kwe-accelerator kunokwenzeka ukufikelela kulo setyenziso.
Kungenjalo, amanani ale njini ayoyikeka: ku-1,000 rpm (ingasebenzi) le njini ihambisa i-450 Nm ye-torque (!) , kodwa kuphakathi kwe-2000 kunye ne-3000 rpm ukuba eli xabiso lifikelela kwincopho yalo, i-760 Nm ye-torque. Kwi-4400 rpm sifikelele kumandla aphezulu: i-440 hp enhle.
Kule nto, kukho i-brand enye kuphela eyenza ngcono, i-Audi. Kodwa ibifuna iisilinda ezingaphezulu kunye nokufuduswa, sithetha ngeV8 TDI entsha ye-Audi SQ7.
Ukubeka eli xabiso ngokwembono siye sachukumiseka ngakumbi. I-BMW 750i xDrive enepetroli ene-449 hp ithatha nje imizuzwana eyi-0.2 ngaphantsi kwe-0-100 km/h kune-750d xDrive.
Okwangoku, le njini ifumaneka kuphela BMW 7 Series, kodwa kusenokwenzeka ukuba kungekudala iza kuvela kwezinye iimodeli ezifana BMW X5 kunye X6. Yizani kubo!
Ingaba abakwaBMW bawafumene njani la maxabiso?
I-BMW yayiluphawu lokuqala ukudibanisa ii-turbos ezintathu ngokulandelelana, kwaye ngoku iphinde ibe nguvulindlela ekudibaniseni ii-turbos ezine ngokulandelelana kwi-injini yedizili.Njengoko usazi, ii-turbos zidinga ukuhamba kwe-exhaust ukuya emsebenzini - masilibale malunga nezinto ezingaphandle kulo mgaqo, ezizezi i-Audi electric turbos okanye iVolvo compressed-air turbos, kuba akunjalo.
Kwi-revs ephantsi le njini ye-3.0 litre six-cylinder isebenzisa kuphela ii-turbos ezinoxinzelelo oluphantsi ezimbini ngaxeshanye. Njengoko kukho uxinzelelo oluncinci lwegesi, kulula ukubeka ii-turbos ezincinci ukuba zisebenze, ngaloo ndlela unqanda into ebizwa ngokuba yi-"turbo-lag". Ewe kunjalo kwii-revs eziphezulu, ezi turbos azingeni...
Yiyo loo nto njengoko isantya se-injini sikhula, njengoko kukho ukwanda kokuhamba kunye noxinzelelo lweegesi zokukhupha, ulawulo lwe-injini ye-elektroniki lunika umyalelo wenkqubo ye-throttle ukuba itshayile zonke iigesi zokukhupha kwi-3rd variable geometry turbo.
Ukusuka kwi-2,500 rpm, i-4th turbo enkulu iqala ukusebenza, enegalelo eliqinisekileyo kwimpendulo ye-injini kwisantya esiphakathi kunye nesiphezulu.
Ke, imfihlo yamandla ale njini ikule turbo kunye nokukhupha igesi yongqamaniso lomdlalo. Kuyaphawuleka akunjalo?
Ukuba isihloko esithi "superdiesel" siphakamisa umdla wakho, siya kukwazi ukubuyela kulo mbandela kungekudala. Sishiye uluvo lwakho kuFacebook wethu kwaye wabelane ngemixholo yethu.
