Tsis muaj qhov tsis ntseeg tias huab cua zoo thiab kev hloov pauv huab cua yog tus tsav tsheb tseem ceeb hauv ntiaj teb.Yuav ua li cas txhim kho powertrain dynamics thaum ua tau raws li yav tom ntej CO2 thiab emission lub hom phiaj tseem yog ib qho kev sib tw thiab yuav xav tau cov kev hloov pauv tseem ceeb thiab cov thev naus laus zis siab heev.
Raws li qee cov ntaub ntawv tshaj tawm kev tshaj lij, ntawm no yog ob lub tshuab hluav taws xob siv hluav taws xob feem ntau sib ntsib rau kev txo qis CO2.
Ua ntej, ib qho kev ua tau zoo tab sis kev sib piv yooj yim thiab tus nqi siv tau ua pov thawj los ua qhov hu ua Variable Geometry System, (VGS) tuaj yeem txo qhov kev tsis sib haum xeeb no.VGS kev ua tau zoo kuj raug txwv vim kev ua haujlwm dav dav yog yuav tsum tau ua.Kev tsim hluav taws xob hluav taws xob ntau ntxiv ua rau muaj peev xwm zoo ntxiv rau kev txo qis kev tsis sib haum xeeb ntawm ib ntus, qis-kawg nyob ruaj khov thiab ntsuas lub zog ntawm lub cav.Kev ua kom zoo ntxiv ntxiv yog tsom rau kev ua tiav tag nrho lub zog zoo sib npaug.Hauv qhov no, kev siv hluav taws xob tuaj yeem siv los txhim kho lub tshuab ua haujlwm.Lawv yog ib qho tseem ceeb ntawm plug thiab ua si technology nyob rau sab saum toj ntawm lub tsheb hybridization.Tsis tas li ntawd, lawv tau sib xws nrog cov geometry turbines sib txawv thiab cov pa roj recirculation daws teeb meem thiab yuav tsis yog cov neeg siv hluav taws xob.
Thib ob, Kev Siv Hluav Taws Xob Tshwj Xeeb (BSFC) txhim kho rau cov haujlwm muaj feem cuam tshuam thiab xav tias yuav txo qis CO2 hauv WLTC.Ib qho tseem ceeb ntawm cov hluav taws xob them hluav taws xob yog lub zog xav tau thaum lub voj voog.Electrifying lub turbocharger tshem tawm qhov txwv ntawm kev xav tau lub tshuab me me nrog kev ua haujlwm zoo los tsav nws lub hnub nyoog thib ob turbocharged.Xws li qhov loj me me hluav taws xob turbocharger tuaj yeem xa cov CO2 txo los ntawm kev txhawb nqa kev txo qis thiab qis qis rau tib lub sijhawm.
Yog li ntawd, lub tshuab hluav taws xob turbocharger yog dimensioned kom lub turbocharger yuav motored thiab braked mus txog thiab nrog rau tag nrho cov turbocharger ceev.Nws tau raug pom tias lub tshuab hluav taws xob turbocharger uas raug cai tuaj yeem muab txoj hauv kev rau cov tuam txhab tsim khoom qub kom tau raws li qee qhov kev sib tw loj hauv engineering, tshwj xeeb yog qhov yuav tsum tau ua raws li kev ua haujlwm ntawm stoichiometric, thaum tseem txhim kho kev ua haujlwm ntawm lawv cov powertrains ntxiv.
