BMW 50d tri-turbo diesel cav ua haujlwm li cas?
Yog hais tias lub tshuab ntxaib-turbo yog ib qho kev sib dhos hu ua sequential lossis parallel, qhov thev naus laus zis ntawm BMW's tri-turbo yuav tsum tau muab sau tseg, uas me ntsis sib txuas ob lub thev naus laus zis. Thov nco ntsoov, yog tias koj tsis muaj lub tswv yim txog turbochargers, kuv caw koj los saib ntawm no.
Peb lub cav turbo no ua haujlwm li cas?
Ua ntej ntawm tag nrho cov, nws yuav tsum tau muab sau tseg hais tias lub supercharger no muaj ob lub me me turbines (1 thiab 3 nyob rau hauv daim duab) nrog txawv geometry, raws li zoo raws li tus qauv loj turbocharger (2 nyob rau hauv daim duab). Txhua qhov tom kawg ua rau qee qhov nrawm, thiab tom qab ntawd lawv raug kuaj pom tsis tu ncua hauv cov hom siab (zoo, yog tias koj tuaj yeem hu qhov kev kub ceev, vim tias cov diesel yeej tsis mus siab heev ...).
Thaum qis revs, qis dua 1500 rpm, thawj turbo (ib qho ntawm ob qhov sib txawv me me geometry sawv daws yuav) yog thov los ntawm cov pa (cov cua tshiab los ntawm sab nraud tseem dhau los ntawm lub turbo loj). Txawm hais tias nws tseem tsis tau ua haujlwm hauv qhov nrawm no). Tom qab ntawd, pib ntawm 1500 rpm, qhov loj yog ncaws hauv ib yam nkaus, vim tias cov pa ntws tawm tam sim no txaus los ua txuj lom. Nco ntsoov tias peb lub turbines tsis tau qhib ua ke txij thaum pib ntawm hom, vim tias qhov no ua pa tsis tseem ceeb txaus rau kev ua haujlwm ntawm peb lub tshuab compressors. Thaum kawg, ntawm 2500 rpm, qhov thib peb thaum kawg tuaj yeem pib ua haujlwm ua tsaug rau qhov qhib lub damper (hu ua bypass), uas tom qab ntawd tso cai rau cov pa tso rau lub turbocharger no (vim kuv ceeb toom koj tias yog lub zog uas tso cai rau koj tsav tsheb. lub cav). turbo yog "cua" uas tsim los ntawm cov pa pa tawm).
Los ntawm qhov kev xav ntawm kev tsim vaj tsev, peb tuaj yeem xav txog turbines 1 thiab 2 raws li nyob rau hauv series nrog hwm rau ib leeg, thaum turbines 1 thiab 3 (ob tug me me) nyob rau hauv parallel.
Thaum pib, cov pa tso pa tawm yog nruab nrab, yog li lub turbine me me yuav siv sij hawm tshaj thawj theem ntawm kev txhawb nqa.
Twb tau ntawm 1500 rpm, lub cav tsim lub zog ntawm 650 Nm!
Lub cav tsim tawm 740 Nm (!) los ntawm 2000 txog 3000 rpm, zoo kawg li piv rau ("tsuas") 381 hp tsim.
Ntawm no yog ib tug nom BMW animation piav qhia nws ua haujlwm li cas:

Kev ntseeg tau?
Kev tshuaj xyuas ntawm lub cav me me no tuaj yeem sib txawv. Ib yam, txawm li cas los xij, yog tias lub tshuab ua kom lub cev muaj zog yuav muaj peev xwm ib txwm ntseeg tau ntau dua li lub cav turbocharged, tshwj xeeb tshaj yog thaum muaj peb ntawm lawv!
