I-BMW 750d xDrive entsha iyimodeli yomkhiqizo waseBavaria enenjini kadizili enamandla kakhulu eyake yaba khona.
Ezigabeni ezingezansi, izinjini zikadizili bezilokhu zilahlekelwa indlela yokukhuluma. Isole ngokukhula kwemithetho yezemvelo, osekwenze izinjini zikadizili zamba eqolo ukuzikhiqiza. Futhi-ke, ukufaneleka kwezinjini ezintsha zikaphethiloli.Esigabeni sokunethezeka le nkinga ayikho, ngoba nje izindleko zokukhiqiza akuyona inkinga. Amakhasimende azimisele ukukhokha noma yini edingekayo ukuze abe nalokhu akufunayo.
AKUMELE UPHUTHELWE: Zonke izindaba (kusuka ku-A kuya ku-Z) embukisweni wezimoto i-Geneva Motor Show ka-2017
Ngisho noma udizili omkhulu! Njengoba kwenzeka ngeBMW 750d xDrive entsha, isaluni kanokusho enesisindo esingaphezu kwamathani amabili ifakwe injini kadizili engu-3.0 litre nama-turbo amane afakwe ngokulandelana. Umphumela osebenzayo yilokhu:
Njengoba ubona, i-750d entsha iyisitimela sangempela sikadizili, ekwazi ukusuka ku-0 iye ku-100 km/h ngemizuzwana engu-4.6 futhi isuke ku-0 iye ku-200 km/h ngemizuzwana engu-16.8. Ukusetshenziswa okukhangiswayo (umjikelezo we-NEDC) ngu-5.7 l/100km - ekugcineni lapho isipikili sibheke phezulu phezu kwe-accelerator kungenzeka ukuthi ufinyelele kulokhu kudla.
Uma kungenjalo, izinombolo zale njini ziningi kakhulu: ku-1,000 rpm (ayisebenzi) le njini iletha i-torque engu-450 Nm(!) , kodwa kuphakathi kuka-2000 no-3000 rpm lapho leli nani lifinyelela umvuthwandaba walo, i-torque engu-760 Nm. Ngo-4400 rpm sifinyelele amandla aphezulu: i-440 hp enhle.
Kulokhu, kunomkhiqizo owodwa kuphela owenza kangcono, i-Audi. Kodwa ibidinga amasilinda amaningi kanye nokufuduka okwengeziwe, sikhuluma nge-V8 TDI entsha ye-Audi SQ7.
Ukubeka leli nani ngombono sihlabeke umxhwele nakakhulu. I-BMW 750i xDrive edla uphethiloli enamandla angu-449 hp ithatha imizuzwana engu-0.2 kuphela ukusuka ku-0-100 km/h kune-750d xDrive.
Okwamanje, le njini itholakala kuphela kwi-BMW 7 Series, kodwa kungenzeka ukuthi izovela maduze kwezinye izinhlobo ezifana neBMW X5 neX6. Wozani bo!
I-BMW iwathole kanjani lawa magugu?
I-BMW ibe wuhlobo lokuqala ukuhlanganisa ama-turbos amathathu elandelana, futhi manje isiphinde yaba yingqalabutho ekuhlanganiseni ama-turbo amane elandelana enjinini kadizili.Njengoba wazi, ama-turbos adinga ukugeleza kwe-exhaust ukuze asebenze - ake sikhohlwe ngokuhlukile kulo mthetho, okuyi-Audi electric turbos noma i-Volvo compressed-air turbos, ngoba akunjalo.
Uma isezingeni eliphansi le njini engu-3.0 litre six-cylinder isebenzisa kuphela ama-low-pressure turbos amabili ngesikhathi esisodwa. Njengoba kunomfutho wegesi omncane, kulula ukubeka ama-turbos amancane ukuze asebenze, ngaleyo ndlela ugweme lokho okubizwa ngokuthi "i-turbo-lag". Yebo kuma-rev aphezulu, lawa ma-turbo awalingani...
Kungakho njengoba ijubane lenjini likhula, njengoba kuba nokunyuka kokugeleza nokucindezela kwamagesi e-exhaust, isilawuli senjini ye-elekthronikhi sinikeza isistimu ye-throttle ukuze idlulisele wonke amagesi e-exhaust ku-3rd variable geometry turbo. high pressure.
Ukusuka ku-2,500 rpm, i-turbo yesi-4 enkulu iqala ukusebenza, enikela ngokusobala ekuphenduleni kwenjini ngesivinini esiphakathi nendawo nesiphezulu.
Ngakho-ke, imfihlo yamandla ale njini ikule game yokuvumelanisa i-turbo ne-exhaust gas. Kuyaphawuleka akunjalo?
