Cav 1G-FE Toyota

1G cav series tau suav nws cov keeb kwm txij li xyoo 1979, thaum 2-valve in-line "rau" nrog 12G-EU Performance index pib muab rau Toyota conveyors rau equipping rear-wheel tsav tsheb ntawm E thiab E + chav kawm (Crown, Mark 1, Chaser, Cresta, Soarer) thawj zaug . Nws yog nws uas tau hloov nyob rau hauv 1988 los ntawm nto moo 1G-FE cav, uas tau ntau xyoo muaj lub npe tsis raws cai ntawm lub feem ntau txhim khu kev qha chav tsev nyob rau hauv nws cov chav kawm ntawv.

1G-FE Beams hauv Toyota Crown

1G-FE tau tsim tsis hloov pauv rau yim xyoo, thiab xyoo 1996 nws tau raug kho me me, vim tias lub zog siab tshaj plaws thiab lub zog ntawm lub cav "loj" los ntawm 5 units. Qhov kev kho kom zoo no tsis muaj feem cuam tshuam rau kev tsim qauv ntawm 1G-FE ICE thiab tau tshwm sim los ntawm lwm qhov kev so ntawm Toyota nrov qauv, uas tau txais, ntxiv rau lub cev hloov tshiab, lub zog "muscular" ntau dua.

Kev tsim kho tshiab sib sib zog nqus tos lub cav hauv xyoo 1998, thaum cov qauv kev ua kis las Toyota Altezza xav tau lub cav ntawm kev teeb tsa zoo sib xws, tab sis nrog kev ua tau zoo dua. Toyota designers tswj kom daws tau qhov teeb meem no los ntawm kev ua kom ceev ntawm lub internal combustion engine, ua kom lub compression piv thiab qhia ib tug xov tooj ntawm niaj hnub khoom siv hluav taws xob rau hauv lub tog raj kheej taub hau. Tus qauv tshiab tau txais ib qho ntxiv ua ntej rau nws lub npe - 1G-FE BEAMS (Breakthrough Cav nrog Advanced Mechanism System). Qhov no txhais tau hais tias lub combustion engine nyob rau hauv lub sij hawm yog nyob rau hauv lub chav kawm ntawm cov niaj hnub motors uas siv advanced mechanisms thiab systems.

Nws tseem ceeb heev. Lub cav 1G-FE thiab 1G-FE BEAMS muaj cov npe zoo sib xws, tab sis hauv kev xyaum lawv yog cov zog sib txawv kiag li, feem ntau ntawm cov khoom tsis sib hloov.

Tsim thiab specifications

Lub cav 1G-FE belongs rau tsev neeg ntawm in-line 24-valve rau-lub tog raj kheej sab hauv combustion xyaw nrog ib txoj siv tawv tsav mus rau ib lub camshaft. Qhov thib ob camshaft yog tsav los ntawm thawj zaug los ntawm ib qho tshwj xeeb iav ("TwinCam nrog lub taub hau nqaim").

Kev paub txog kev ua haujlwm thiab kev saib xyuas

Tag nrho cov keeb kwm ntawm kev ua haujlwm ntawm 1G series cav tau lees paub cov kev xav tau tsim los ntawm lawv cov kev ntseeg siab thiab kev tsis txaus ntseeg. Cov kws tshaj lij kos cov xim ntawm cov tswv tsheb rau tsuas yog ob lub ntsiab lus: qhov yuav tsum tau saib xyuas qhov xwm txheej ntawm txoj siv sia lub sijhawm thiab qhov tseem ceeb ntawm lub sijhawm hloov cov roj cav. Lub VVTi valve, uas yooj yim ua rau txhaws, yog thawj zaug raug kev txom nyem los ntawm cov roj qub lossis cov roj tsis zoo. Feem ntau qhov ua rau muaj kev ua haujlwm tsis zoo yuav tsis yog lub cav nws tus kheej, tab sis txuas ntxiv thiab cov tshuab ntxiv uas ua kom nws txoj haujlwm ua haujlwm. Piv txwv li, yog tias lub tsheb tsis pib, thawj qhov yuav tsum tau kuaj xyuas yog lub alternator thiab pib. Lub luag haujlwm tseem ceeb tshaj plaws hauv "kev noj qab haus huv" ntawm lub cav yog ua si los ntawm cov ntsuas kub thiab dej twj tso kua mis, uas muab qhov ntsuas kub zoo. Feem ntau ntawm cov teeb meem nrog lub cav combustion tuaj yeem txheeb xyuas los ntawm kev kuaj tus kheej ntawm Toyota lub tsheb - lub peev xwm ntawm cov khoom siv hluav taws xob ntawm lub tsheb "kho" cov kev ua haujlwm tsis zoo uas tshwm sim hauv cov tshuab thiab tso saib lawv thaum muaj qee yam kev ua haujlwm tshwj xeeb. cov khoom sib txuas.

Thaum lub sijhawm ua haujlwm hauv ICE 1G, cov teeb meem hauv qab no feem ntau tshwm sim:

1. Leakage ntawm cav roj los ntawm lub siab sensor. Tshem tawm los ntawm kev hloov lub sensor nrog ib qho tshiab.
2. Tsawg roj siab tswb. Feem ntau, nws yog tshwm sim los ntawm ib tug puas sensor. Tshem tawm los ntawm kev hloov lub sensor nrog ib qho tshiab.
3. Idle ceev instability. Qhov kev tsis zoo no tuaj yeem tshwm sim los ntawm kev ua haujlwm tsis zoo ntawm cov khoom siv hauv qab no: tsis siv lub valve, lub valve throttle lossis qhov ntsuas qhov ntsuas qhov ntsuas. Tshem tawm los ntawm kev kho lossis hloov cov khoom siv tsis raug.
4. Nyuaj pib lub cav txias. Yog vim li cas: lub txias pib injector tsis ua hauj lwm, lub compression nyob rau hauv lub tog raj kheej yog tawg, lub sij hawm cov cim yog teem tsis raug, lub thermal clearances ntawm lub li qub tsis tau raws li lub tolerances. Tshem tawm los ntawm kev teeb tsa kom raug, hloov kho lossis hloov cov khoom siv tsis raug;
5. Kev siv roj ntau (ntau dua 1 liter ib 10000 km). Feem ntau tshwm sim los ntawm "tso tawm" ntawm cov roj scraper rings thaum lub sijhawm ua haujlwm ntev ntawm lub tshuab hluav taws xob sab hauv. Yog hais tias tus qauv decarbonization ntsuas tsis pab, ces tsuas yog ib tug loj overhaul ntawm lub cav yuav pab tau.

Hauv qab no yog cov npe ntawm cov haujlwm uas yuav tsum tau ua yam tsis tau poob tom qab ib mais deb:

• cav roj hloov - tom qab 10 txhiab km. Toyota cov lus pom zoo: rau 1G-FE - 5W30 (5W20) SJ roj; rau 1G-FE BEAMS - 5W20 SL / GF-3. Lub ntim ntim yog 3.9 litres, cov roj lim muaj 0.2 litres.
• hloov lub sij hawm siv cov khoom siv - tom qab 100 txhiab km. Thaum lub sijhawm ua haujlwm no, lub twj tso kua mis feem ntau yog hloov;
• hloov lub txim plugs - tom qab 20 txhiab km. Rau 1G-FE, tswm ciab 90919-01164 (Denso K16R-U11) yog siv, rau 1G-FE BEAMS 90919-01184 (Denso K20PR-U11);
• roj lim hloov - tom qab 20 txhiab km. Rau 1G-FE roj lim 23300-79145 (ua ntej 08.1990) thiab 23300-79146 (tom qab 08.1990). Nws nyob hauv qab lub hood, nyob ib sab ntawm lub tsheb ciav hlau. Rau 1G-FE BEAMS lim 23300-21010, nyob rau hauv lub tank;
• Kev kuaj xyuas thiab kho li qub nrog cov ntxhua khaub ncaws ntawm lub cav txias (valve clearances: intake 0.15-0.25 mm, exhaust 0.25-0.35 mm) - tom qab 20 txhiab kilometers (rau 1G-FE BEAMS).

Xyuas

Ntau yam kev tshuaj xyuas txog 1G-FE thiab 1G-FE BEAMS tuaj yeem muab faib ua ob pawg: kev tshuaj xyuas cov kws tshaj lij koom nrog kev saib xyuas thiab kho cov motors, thiab kev tshuaj xyuas cov neeg tsav tsheb zoo tib yam. Cov yav tas los yog unanimous nyob rau hauv lub fact tias ib tug sib sib zog nqus Modernization ntawm lub engine nyob rau hauv 1998 ua rau ib tug general txo nyob rau hauv kev cia siab rau, durability thiab kev ruaj ntseg ntawm chav tsev. Tab sis txawm lawv lees tias 250-300 txhiab km ntawm kev khiav, ob qho tib si ntawm lub tshuab hluav taws xob sab hauv tsis ua rau muaj kev tsis txaus siab hauv yuav luag txhua qhov haujlwm. Cov tswv tsheb ib txwm muaj kev xav ntau dua, tab sis lawv cov kev tshuaj xyuas rau feem ntau kuj muaj txiaj ntsig zoo. Muaj ntau cov lus ceeb toom tias cov cav no tau ua haujlwm zoo ntawm lub tsheb rau 400 lossis ntau txhiab mais.
