4A-GE cav
Txheem
Txoj kev loj hlob ntawm Toyota's A-series roj av sab hauv combustion xyaw pib hauv 1970. Tag nrho cov tswv cuab ntawm tsev neeg yog nyob rau hauv-kab plaub-lub tog raj kheej hwj chim units nrog ib tug ntim ntawm 1,3 mus rau 1,8 litres. Lub cam khwb cia hlau lub tog raj kheej thaiv yog tsim los ntawm casting, lub taub hau thaiv yog ua los ntawm txhuas. Lub A series tau tsim los ua ib qho kev hloov pauv rau plaub-lub tog raj kheej hauv-kab qis-lub zog ntawm K tsev neeg, uas, tsis yog qhov xav tsis thoob, tau tsim los txog rau xyoo 2007. Lub cav 4A-GE, thawj plaub-lub tog raj kheej hauv-kab DOHC lub zog, tau tshwm sim hauv xyoo 1983 thiab tau tsim nyob rau hauv ntau lub versions txog 1998.
Tsib tiam
Cov tsiaj ntawv GE nyob rau hauv lub cav lub npe qhia txog kev siv ob lub camshafts nyob rau hauv lub sij hawm mechanism thiab ib tug hluav taws xob txhaj tshuaj system. Lub taub hau txhuas lub tog raj kheej yog tsim los ntawm Yamaha thiab tsim los ntawm Toyota's Shimoyama cog. NW nyuam qhuav tshwm sim, 4A-GE tau txais txiaj ntsig zoo ntawm cov neeg nyiam kho, muaj sia nyob tsib qhov kev hloov kho loj. Txawm hais tias tshem tawm lub cav los ntawm kev tsim khoom, muaj cov khoom tshiab rau kev muag khoom, tsim los ntawm cov tuam txhab me me rau cov neeg nyiam overclocking.

Thawj tiam tau hloov lub 80T-G cav nrov nyob rau hauv lub 2s, nyob rau hauv lub tsim ntawm lub gas tis mechanism uas ob camshafts twb siv nyob rau hauv lub sij hawm ntawd. Lub zog ntawm toyota 4A-GE ICE yog 112 hp. ntawm 6600 rpm rau Asmeskas lag luam, thiab 128 hp. rau Japanese. Qhov txawv yog nyob rau hauv lub installation ntawm huab cua flow sensors. Cov American version, nrog ib tug MAF sensor, txwv airflow nyob rau hauv lub engine lub intake manifold, ua rau ib tug me ntsis poob rau hauv lub hwj chim, tab sis ib tug ntau huv si pa. Hauv Nyij Pooj, cov kev cai emission tau nruj me ntsis thaum lub sijhawm. Lub MAP huab cua ntws sensor nce lub zog lub cav, thaum tsis muaj kev ua phem rau ib puag ncig.
Qhov zais cia ntawm 4A-GE yog qhov txheeb ze ntawm qhov nkag thiab tso tawm li qub. Lub kaum sab xis ntawm 50 degrees nruab nrab ntawm lawv muab cov kev pom zoo rau lub cav ua haujlwm ntawm kev kub ceev, tab sis sai li sai tau thaum koj tso cov pa tawm, lub zog poob mus rau qib qub K series.
Txhawm rau daws qhov teeb meem no, T-VIS system tau tsim los tswj cov geometry ntawm cov khoom siv manifold thiab yog li ua kom lub zog ntawm plaub-lub tog raj kheej sab hauv combustion engine. Txhua lub tog raj kheej muaj ob txoj kev sib cais, ib qho tuaj yeem raug thaiv nrog lub throttle. Thaum lub cav ceev poob mus rau 4200 ib feeb, T-VIS kaw ib qho ntawm cov channel, ua rau cov cua ntws nce, uas tsim kom muaj kev sib haum xeeb rau kev sib xyaw ntawm cov roj-cua sib tov. Kev tsim cov thawj tiam cav siv sijhawm plaub xyoos thiab xaus rau xyoo 1987.

Lub cim thib ob yog qhov txawv los ntawm qhov nce ntawm txoj kab uas hla ntawm crankshaft phau ntawv xov xwm, uas muaj txiaj ntsig zoo rau cov peev txheej ntawm lub cav. Lub tog raj kheej thaiv tau txais plaub qhov txias txias ntxiv, thiab lub tog raj kheej lub taub hau npog tau pleev xim rau xim dub. 4A-GE tseem tau nruab nrog T-VIS system. Kev tsim tawm thib ob tau pib hauv xyoo 1987 thiab xaus rau xyoo 1989.

Lub cim thib peb tau hloov pauv loj rau lub cav tsim. Toyota Corporation engineers tso tseg kev siv T-VIS system, tsuas yog txo cov geometric qhov ntev ntawm cov khoom siv manifold. Ib tug xov tooj ntawm kev txhim kho tau ua kom lub neej ntawm lub cav. Tus qauv tsim ntawm lub pistons tau hloov pauv - tam sim no lawv tau nruab nrog cov ntiv tes nrog ib txoj kab uas hla ntawm nees nkaum millimeters, nyob rau hauv sib piv rau kaum yim millimeter ntiv tes ntawm cov tiam dhau los. Ntxiv lubrication nozzles yog ntsia hauv qab pistons. Txhawm rau them nyiaj rau qhov poob ntawm lub zog los ntawm kev tso tseg ntawm T-VIS system, cov neeg tsim qauv tau nce qhov sib piv ntawm 9,4 txog 10,3. Lub tog raj kheej lub taub hau npog tau txais cov xim nyiaj thiab ib tsab ntawv liab. Lub cim thib peb ntawm lub cav yog ruaj khov rau hauv lub npe menyuam yaus Redtop. Kev tsim khoom tau tso tseg hauv 1991.
Qhov no xaus zaj dab neeg ntawm 16-valve 4A-GE. Kuv xav ntxiv tias thawj ob tiam neeg tseem mob siab rau kev hlub los ntawm cov kiv cua ntawm Fast thiab Furious zaj yeeb yaj kiab series kom yooj yim kho dua tshiab.
4 tiam
Lub cim thib plaub tau cim los ntawm kev hloov pauv mus rau ib qho kev tsim siv tsib li qub rau ib lub tog raj kheej. Raws li lub tswv yim nees nkaum-valve, lub tog raj kheej lub taub hau tau raug kho dua tshiab. Ib qho tshwj xeeb VVT-I roj faib tshuab tau tsim thiab siv, qhov sib piv tau nce mus rau 10,5. Tus distributor yog lub luag hauj lwm rau ignition. Txhawm rau kom muaj kev ntseeg siab thiab kev pabcuam lub neej ntawm lub cav, lub crankshaft tau raug kho dua tshiab.
Lub tog raj kheej lub taub hau npog tau txais cov xim nyiaj nrog chrome ntawv ntawm nws. Lub 4A-GE Silvertop moniker tau daig nrog lub tshuab thib plaub. Qhov kev tso tawm tau dhau los ntawm 1991 txog 1995.
5 tiam
Lub cim thib tsib tau tsim nrog lub zog siab tshaj plaws hauv siab. Lub compression ratio ntawm cov roj sib tov yog nce, thiab yog sib npaug zos rau 11. Cov kev ua hauj lwm stroke ntawm lub intake li qub tau lengthened los ntawm 3 hli. Lub intake manifold kuj tau hloov kho. Vim qhov zoo tshaj plaws geometric duab, qhov ntim ntawm lub tog raj kheej nrog cov roj sib tov tau zoo tuaj. Qhov dub npog npog lub tog raj kheej taub hau yog vim li cas rau lub npe "nrov" ntawm lub cav 4A-GE Blacktop.

Lub neej thib ob 4A-GE
Ua tsaug rau qhov tsim tau zoo heev, lub cav yog nrov heev txawm tias 15 xyoo tom qab kev tsim khoom. Qhov muaj cov khoom tshiab ua rau kho 4A-GE yog ib txoj haujlwm yooj yim. Tuning kiv cua tswj kom nce lub zog ntawm 16-valve engine los ntawm nominal 128 hp. mus 240!
Yuav luag tag nrho cov khoom ntawm lub cav txheem tau hloov kho. Lub tog raj kheej, cov rooj zaum thiab daim hlau ntawm cov khoom noj thiab cov pa tawm yog hauv av, camshafts nrog lub sijhawm sib txawv ntawm lub Hoobkas tau teeb tsa. Kev nce qib ntawm compression ntawm cov roj-cua sib tov yog ua tiav thiab, vim li ntawd, kev hloov pauv mus rau roj nrog tus lej octane siab tau ua tiav. Cov txheej txheem tswj hluav taws xob tau hloov pauv.
Thiab qhov no tsis yog qhov txwv. Cov kiv cua ntawm lub zog loj, cov kws kho tsheb txawj ntse thiab cov kws tsim khoom tab tom nrhiav ntau thiab ntau txoj hauv kev tshiab los tshem tawm qhov ntxiv "kaum" los ntawm crankshaft ntawm lawv tus hlub 4A-GE.
