Tsis muaj kev tsis ntseeg tias huab cua zoo thiab huab cua yog cov tsav tsheb tseem ceeb nyob rau hauv tag nrho lub ntiaj teb. Yuav ua li cas txhawm rau txhim kho poteltrain fynamics thaum ua tau raws li yav tom ntej CO2 thiab emission cov phiaj xwm tseem ceeb thiab yuav xav tau kev hloov pauv thiab cov thev naus laus zis siab.
Raws li qee cov ntaub ntawv cov ntaub ntawv tshaj lij, ntawm no yog ob feem ntau siv siv hluav taws xob cov tshuab sib xws.
Firstly tseem muaj txiaj ntsig tau yooj yim thiab muaj txiaj ntsig zoo tau ua pov thawj los ua tus hu ua varometry system, (vgs) tuaj yeem ua kev sib haum xeeb no. VGS kev ua tau zoo kuj muaj kev txwv txij li kev ua haujlwm dav-ntau yog yuav tsum tau ua. Ncaim hluav taws xob nce hluav taws xob hluav taws xob nqa cov peev xwm zoo rau kev sib cav txog kev tsis sib haum xeeb ntawm lub xeev ib ntus, qis-lub zog uas yuav tsum muaj lub cav. Cov kev xaiv ntxiv yog tsom rau kev ua tiav lub zog zoo tag nrho. Hauv qhov no, kev teeb hluav taws xob tuaj yeem siv los txhim kho cov cuab yeej cuab tam tau. Lawv yog qhov tseem ceeb ib qho ntsaws thiab ua si thev naus laus zis nyob rau sab saum toj ntawm cov tsheb hybridization. Tsis tas li ntawd, lawv tau tshaj tawm cov kev sib txawv geometry turbines raws li kev tso tawm roj recirculation daws teeb meem thiab yuav tsis yog tus neeg siv khoom hluav taws xob.
Thib ob, nres kev noj roj tshwj xeeb (BSFC) txhim kho rau kev ua haujlwm muaj feem thiab kev cia siab txo qis ntawm CO2 hauv WLTC. Ib qho tseem ceeb ntawm lub tshuab hluav taws xob yog lub zog uas xav tau thaum lub voj voog. Hluav taws xob lub turbocharger tshem tawm cov kev txwv ntawm kev xav tau ib qho me me turbine nrog tau zoo ua haujlwm kom tsav nws lub hnub nyoog turbocharged. Xws li cov hluav taws xob hluav taws xob hluav taws xob muaj zog tuaj yeem xa CO2 txo los ntawm kev txhawb nqa downsizing thiab qis ceev tib lub sijhawm.
Raws li qhov tshwm sim, lub tshuab hluav taws xob turbocharger yog qhov loj me yog li ntawd lub turbocharter tej zaum yuav muaj lub cev thiab braked mus thiab suav nrog tag nrho turbocharger ceev. Nws tau pom tias qhov muaj zog hluav taws xob muaj zog tuaj yeem muab txoj kev ua haujlwm qub, thaum tseem txhim kho kev ua haujlwm ntawm lawv cov kev ua tau zoo ntxiv.
