Kodi injini ya dizilo ya BMW 50d tri-turbo imagwira ntchito bwanji?
Ngati ma twin-turbo systems ndi gulu lomwe limadziwika kuti sequential kapena parallel, mbali yaukadaulo ya BMW's tri-turbo iyenera kudziwidwa, yomwe imaphatikiza matekinoloje awiriwa. Chonde dziwani, ngati simukudziwa za ma turbocharger, ndikukupemphani kuti muwone apa.
Kodi injini zitatu za turbo zimagwira ntchito bwanji?
Choyamba, tisaiwale kuti supercharging dongosolo ili ndi turbines awiri ang'onoang'ono (1 ndi 3 pa chithunzi) ndi geometry variable, komanso lalikulu turbocharger (2 pa chithunzi). Iliyonse yotsirizayi imayendetsa liwiro linalake, ndiyeno imadziwika mosadukiza mumayendedwe apamwamba (chabwino, ngati mutha kuyitcha kuthamanga kwambiri, chifukwa ma dizilo samakwera kwambiri ...).
Pa ma revs otsika, pansi pa 1500 rpm, turbo yoyamba (imodzi mwazinthu ziwiri zazing'ono za geometry) imafunsidwa ndi mpweya (mpweya wabwino ukubwera kuchokera kunja ukudutsabe turbo yaikulu). Ngakhale sichikugwira ntchito pa liwiro ili). Kenaka, kuyambira pa 1500 rpm, yaikulu imakankhiranso, chifukwa kutuluka kwa mpweya tsopano kuli kokwanira kuti kununkhira. Kumbukirani kuti ma turbines atatu sanalowetsedwe pamodzi kuyambira pachiyambi cha mode, chifukwa pamenepa kupuma sikofunikira mokwanira pa ntchito ya compressor atatu. Pomaliza, pa 2500 rpm, wachitatu amatha kuyamba kugwira ntchito chifukwa cha kutsegula kwa damper (yotchedwa bypass), yomwe imalola kuti mpweya wotulutsa mpweya uperekedwe ku turbocharger iyi (chifukwa ndikukumbutsani kuti ndi mphamvu yomwe imakulolani kuyendetsa galimoto. injini). turbo ndi "mphepo" yopangidwa ndi mpweya wotulutsa mpweya).
Kuchokera pamalingaliro omanga, titha kuganiza za ma turbines 1 ndi 2 ngati akutsatizana ndi wina ndi mnzake, pomwe ma turbines 1 ndi 3 (awiri ang'onoang'ono) ali ofanana.
Pachiyambi, mpweya wotulutsa mpweya umayenda pang'onopang'ono, choncho turbine yaying'ono imatenga gawo loyamba la mphamvu.
Kale pa 1500 rpm injini akufotokozera makokedwe 650 Nm!
Injini akufotokozera 740 NM (!) kuchokera 2000 mpaka 3000 rpm, zosaneneka poyerekeza ndi ("okha") 381 HP opangidwa.
Nayi makanema ojambula ovomerezeka a BMW akufotokoza momwe amagwirira ntchito:
Makanema okhala ndi BMW triple turbo diesel engine - M550d xDrive
Kudalirika?
Ndemanga za injini yodziwika kwambiri iyi ikhoza kukhala yochepa. Chinthu chimodzi, komabe, ndikuti injini yofunidwa mwachilengedwe nthawi zonse imakhala yodalirika kuposa injini ya turbocharged, makamaka ikakhala itatu!
