Nyob rau hauv lub era ntawm hluav taws xob tsheb, peb yeej tsis xav tau engine?
Lo lus teb tsis yog. Nyob rau hauv 2023, 13.03 lab lub zog tshiab tsheb tau muag thoob ntiaj teb, ntawm 3.91 lab yog PHEV thiab REEVs nrog lub tshuab hluav taws xob sab hauv, thiab 9.12 lab yog lub tsheb fais fab.
Los ntawm qhov kev xav ntawm kev sib koom thoob ntiaj teb, qhov kev faib ua feem ntawm cov tshuab hluav taws xob sab hauv hauv kev lag luam hluav taws xob tau mus txog li 30%. Hauv kev lag luam hauv tsev, qhov kev loj hlob ntawm PHEV thiab REEV sectors yog qhov pom tseeb heev, thiab tam sim no tau dhau qhov kev loj hlob ntawm EV sectors.
Yog li kuv tau hais tias cov tshuab hluav taws xob sab hauv tseem yog qhov tseem ceeb ntawm kev txhawb nqa hauv lub sijhawm ntawm cov tsheb hluav taws xob.
Ib qho yog tias cov tsheb tshiab lub zog nrog lub tshuab hluav taws xob sab hauv tsis muaj kev ntxhov siab, thiab lawv qhov ntau thiab lub zog ntxiv yog tib yam li cov tsheb roj av, thiab lawv txoj kev nyab xeeb zoo dua li cov tsheb hluav taws xob ntshiab uas muaj cov roj teeb loj. Lwm qhov yog tias cov cuab yeej siv hluav taws xob sab hauv combustion yog qhov paub tab thiab tus nqi qis heev. Piv nrog cov tsheb hluav taws xob ntshiab uas muaj cov roj teeb loj, tus nqi qis heev.
Hauv kev khiav hluav taws xob, cov khoom muab los ntawm cov neeg muag khoom tau daws cov teeb meem kev lag luam ntawm ntau lub tuam txhab. Hauv lwm lo lus, cov khoom muaj zog ntawm ntau cov qauv hluav taws xob ntshiab tsis tuaj yeem qhib qhov sib txawv ncaj qha, tshwj xeeb tshaj yog nyob rau hauv PHEV architecture. Lub ntsiab lus tseem ceeb los qhib qhov sib txawv ntawm cov khoom lag luam yog lub cav combustion sab hauv.
Cov cav sib xyaw ua ke zoo heev tuaj yeem muab cov kev txhawb nqa tseem ceeb hauv qab no rau cov tuam txhab:
1. Lub xeev ua haujlwm zoo dua thaum pub lub zog. Yog tias lub tshuab hluav taws xob sab hauv hluav taws xob tsis zoo txaus, tag nrho lub tsheb yuav tsis muaj kev ua tau zoo thiab NVH nyob rau hauv kev ua haujlwm ntawm ob qho tib si tsav tsheb thiab tsim hluav taws xob.
2. Nyob rau hauv lub REEV architecture, cov roj noj ntawm ib tug zoo nyob rau hauv combustion engine yuav twv yuav raug hu qis dua vim hais tias lub hwj chim tsim efficiency yog siab dua.
3. Zoo dua durability thiab stability. Ntau lub tuam txhab tau tsis quav ntsej txog qhov tseem ceeb ntawm cov tshuab hluav taws xob sab hauv, uas ua rau muaj teeb meem xws li co thiab nrov nrov thaum lub tsheb khiav, thiab cov ntsiab lus tsis zoo.
Nyob rau hauv lwm yam lus, tag nrho cov tshiab zog tsheb nrog combustion engine, yog hais tias lawv xav mus txhim kho cov ntsiab lus, thaum kawg yuav tsum tau zoo heev internal combustion engine los muab kev txhawb nqa.
Toyota tau hais tias nws yuav tsis tso tseg txoj kev tshawb fawb thiab kev txhim kho ntawm lub tshuab hluav taws xob sab hauv, uas tau thuam los ntawm ntau tus neeg netizens, uas ntseeg tias Toyota tau thim rov qab keeb kwm, tab sis qhov tseeb tsis yog li ntawd. Yeej, txhua lub tuam txhab hauv tsev tsis tau tso tseg kev tshawb fawb thiab kev txhim kho ntawm cov tshuab hluav taws xob sab hauv.
Great Wall's 3.0T thiab Chery's 2.0T yog ob qho tib si khoom zoo heev. Cov tuam txhab tsom mus rau plug-in hybrids kuj tau tsim 1.5L thiab 1.5T plug-in hybrid xyaw. Lub hom phiaj yog khaws cov kev ua tau zoo, kev siv roj, thiab NVH kev paub ntawm lub tsheb thaum ua haujlwm hluav taws xob. Cov ntsiab lus no tsis tau hnov qab, uas yog lub hauv paus tseem ceeb rau kev ua tau zoo ntawm cov neeg sib tw yav tom ntej.
Kev txhim kho yav tom ntej ntawm kev lag luam tsheb neeg caij tsheb yog qhov tseeb hluav taws xob, tab sis qhov tob ntawm kev siv hluav taws xob yog nqa tawm hauv theem.
Nyob rau hauv lub neej yav tom ntej, yuav muaj ntau tus neeg siv uas xaiv cov tsheb hluav taws xob ntshiab, tab sis kuj tseem yuav muaj cov pab pawg loj uas xaiv plug-in hybrid thiab txuas ntxiv-ntau hybrid qauv. Txoj kev technical thiab kev siv scenario yog suav nrog. Qhov tshwm sim ntawm tsuas yog lub tsheb fais fab nkaus xwb yuav ua rau muaj kev kub ntxhov loj rau yav tom ntej infrastructure thiab kev mus ncig ntev. Cov tsheb tshiab lub zog txhawb nqa los ntawm cov tshuab hluav taws xob sab hauv yuav txo qis kev siv roj thaum txhim kho qhov kev paub.
Tshwj xeeb, cov kev paub ntawm cov kev txawj ntse yog qhov muaj zog heev, yog li lub tshuab hluav taws xob sab hauv yuav tsis raug tso tseg, thiab tseem yuav txhim kho yav tom ntej, nrog kev ua haujlwm zoo dua thermal, zoo dua NVH, thiab kev ua haujlwm thermal efficiency hauv txhua qhov xwm txheej yuav maj mam nce.
Ib yam li cov engineers tau sim lawv qhov zoo tshaj plaws los txo cov coefficient, txhua 1% nce hauv kev ua haujlwm thermal efficiency ntawm lub cav combustion sab hauv yuav pab tau zoo rau kev ua siab ntev thiab kev siv zog. Nyob rau hauv lub caij nyoog tam sim no thaum cov kev ua hauj lwm thermal efficiency ntawm lub combustion engine yog tsawg tshaj li 35%, tseem muaj ntau chav rau kev txhim kho.
Nyob rau hauv lub neej yav tom ntej, tsis muaj ntau chav rau kev txhim kho cov roj teeb technology, lub cev muaj zog technology, thiab lub teeb yuag technology. Thaum kawg, peb tseem yuav tsum tau rov qab mus rau kev tsim thiab kev loj hlob ntawm cov tshuab hluav taws xob sab hauv.
