Daim ntawv thov ntawm turbochargers hauv combustion engine tau dhau los ua qhov tseem ceeb hauv xyoo tas los no.Nyob rau hauv cov neeg nrog caij tsheb sector yuav luag tag nrho cov diesel xyaw thiab ntau thiab ntau roj av cav yog nruab nrog ib tug turbocharger.
Compressor lub log ntawm cov pa turbochargers hauv tsheb thiab tsheb thauj khoom yog qhov nyuaj heev.Thaum lub sij hawm txoj kev loj hlob ntawm cov tshiab compressor log, lub hom phiaj yog los tsim ib tug txhim khu kev qha qhov chaw nrog ib tug tsim nyog lub neej raws li zoo efficient thiab tsawg torpor muab kev txhim kho cav efficiency thiab zoo dynamic engine kev ua tau zoo.Txhawm rau ua kom tiav cov kev cai tshwj xeeb ntawm cov yam ntxwv ntawm thermodynamic ntawm lub turbocharger cov khoom ntawm lub compressor log underlies siab txhua yam thiab thermal loads.
Ciam teb tej yam kev mob ntawm lub compressor log nrog rau phab ntsa kub hloov coefficients thiab phab ntsa uas nyob ib sab kub yog muab los ntawm static heat transfer xam.Cov xwm txheej ciam teb yog qhov tsim nyog rau kev hloov hluav taws xob hloov pauv hloov pauv hauv FEA.Kev siv turbocharger thev naus laus zis hauv cov tshuab hluav taws xob me me kuj hu ua "Downsizing".Kev txo qhov hnyav, thiab kev sib txhuam poob thiab qhov nce siab hauv qhov kev sib piv rau cov tshuab hluav taws xob tsis muaj hluav taws xob ua rau lub cav ua kom zoo dua qub thiab qis dua CO2.
Niaj hnub nimno chav turbine tsim yog tshawb nrhiav qhov chaw dav dav kom tau txais kev ua tau zoo.Nyob rau tib lub sijhawm, cov neeg kho tshuab kev ncaj ncees ntawm chav turbine yuav tsum tau khaws cia.Qhov no yuav tsum muaj kev nkag siab tob txog qhov cuam tshuam ntawm txhua qhov kev tsim qauv sib txawv ntawm High Cycle Fatigue (HCF) ntawm chav turbine theem.
Ib qho kev lag luam loj hlob sai ntawm turbocharged roj av cav yuav tsum nyob rau xyoo tom ntej.Qhov kev thov ntawm me me turbocharged combustion xyaw nrog ntau zog ceev thiab ntau dua engine efficiency.
