Mitsubishi 6G72 cav
Txheem
Lub cav no belongs rau Mitsubishi qhov nrov 6G series. Ob hom 6G72 paub: 12-valve (ib lub camshaft) thiab 24-valve (ob lub camshafts). Ob leeg yog 6-lub tog raj kheej V-cav nrog ib qho ntxiv camber kaum sab xis thiab nyiaj siv ua haujlwm camshafts / li qub hauv lub tog raj kheej taub hau. Lub teeb yuag lub cav uas hloov 6G71 tseem nyob ntawm cov kab sib dhos rau 22 xyoo, kom txog rau thaum tuaj txog ntawm 6G75 tshiab.
Cav piav qhia
Xav txog cov yam ntxwv tseem ceeb ntawm lub cav no.
- Lub cav crankshaft so ntawm 4 bearings, cov npog uas tau muab tso rau hauv ib lub txaj kom muaj zog ntawm lub tog raj kheej thaiv.
- Lub cav pistons yog cam khwb cia los ntawm txhuas alloy thiab txuas nrog ib tug floating pin mus rau ib tug txuas pas nrig.
- Cov piston rings yog cam khwb cia hlau: ib tug muaj ib tug conical nto nrog ib tug bevel.
- Composite roj scraper rings, hom scraper, endowed nrog lub caij nplooj ntoos hlav expander.
- Lub taub hau lub tog raj kheej muaj cov tsev pheebsuab-hom combustion chambers.
- Lub cav li qub yog ua los ntawm cov hlau refractory.
- Hydraulic compensators yog tsim los kho qhov sib txawv ntawm tus tsav.
Qhov sib txawv ntawm SOHC thiab DOHC cov phiaj xwm tsim nyog tau txais kev saib xyuas tshwj xeeb.
- Lub camshaft ntawm SOHC version yog cam khwb cia, nrog 4 bearings, tab sis lub camshafts ntawm DOHC version muaj 5 bearings, tsau nrog tshwj xeeb npog.
- Lub sij hawm siv ntawm lub cav dual camshaft yog kho los ntawm qhov tsis siv neeg tensioner. Cov chais yog nrum los ntawm aluminium alloy, muaj kev pab lub neej ntev.
Peb nco txog lwm yam nta.
- Lub cav ntim yog xyaum tsis hloov rau ntau yam kev hloov kho - raws nraim 3 litres.
- Aluminium pistons yog tiv thaiv los ntawm graphite txheej.
- Cov combustion chambers nyob rau hauv lub tog raj kheej taub hau, lawv yog lub tsev pheebsuab-puab.
- Kev teeb tsa ntawm kev txhaj tshuaj ncaj qha GDI (ntawm qhov kev hloov kho tshiab 6G72).
Lub zog tshaj plaws hauv kev hloov kho ntawm 6G72 lub cav yog lub turbo version, uas tsim 320 hp. Nrog. Lub cav no tau nruab rau ntawm Dodge Steal thiab Mitsubishi 3000 GT.
Nws yog ib qho tseem ceeb uas ua ntej qhov tshwm sim ntawm Cyclon tsev neeg, lub tuam txhab MMC tau txaus siab rau hauv kab "plaub". Tab sis nrog lub advent ntawm loj SUVs, minivans thiab crossovers, yuav tsum tau rau ntau haib units. Yog li ntawd, hauv kab "plaub" tau hloov los ntawm V-shaped "rau", thiab qee qhov kev hloov kho tau txais ob lub camshafts thiab lub tog raj kheej taub hau.
Cov neeg tsim khoom tau tsom mus rau cov hauv qab no thaum lub sij hawm tsim cov cav tshiab:
- sim ua kom muaj zog, siv lub turbocharged version;
- sim txo cov roj noj, nws modernized lub valve system.
6G72 roj noj tau nce mus rau 800 g / 1000 km, uas tau piav qhia los ntawm qee qhov kev ua haujlwm. Overhaul tuaj yeem tshaj tawm nws tus kheej tom qab 150-200 txhiab khiav.
Qee cov kws tshaj lij piav qhia ntau yam kev hloov kho ntawm 6G72 los ntawm kev muaj peev xwm sib txawv ntawm lub cav fais fab. Yog li, nws tuaj yeem tsim, nyob ntawm qhov version: 141-225 hp. Nrog. (kev hloov kho yooj yim nrog 12 lossis 24 li qub); 215-240 hli. Nrog. (version nrog ncaj qha roj txhaj); 280-324 ib. Nrog. (turbocharged version). Qhov tseem ceeb torque kuj txawv: rau ib txwm ua raws li cov kev xav tau - 232-304 Nm, rau cov turbocharged - 415-427 Nm.
Hais txog kev siv ob lub camshafts: txawm tias qhov tseeb tias 24-valve tsim tau tshwm sim ua ntej, DOHC cov tswv yim tsuas yog siv thaum ntxov 90s ntawm lub xyoo pua xeem. Ua ntej 24-valve versions ntawm lub cav muaj tsuas yog ib lub camshaft. Qee tus ntawm lawv siv GDI ncaj qha txhaj tshuaj, uas nce qhov sib piv compression.
Lub turbocharged version ntawm 6G72 yog nruab nrog MHI TD04-09B compressor. Ob lub tshuab txias ua haujlwm nyob rau hauv tandem nrog nws, vim tias ib qho intercooler tsis tuaj yeem muab qhov xav tau ntawm huab cua rau rau lub tog raj kheej. Tus tshiab version ntawm 6G72 cav siv niaj hnub pistons, roj txias, injectors, thiab sensors.
Interestingly, rau cov European lag luam, 6G72 turbo xyaw tuaj nrog TD04-13G compressor. Qhov kev xaiv no tau tso cai rau lub tshuab fais fab kom ncav cuag lub zog ntawm 286 litres. Nrog. ntawm boost siab ntawm 0,5 bar.

Qhov zoo thiab qhov tsis zoo
Kev txhim khu kev qha thiab kev tsim khoom siab ntawm 6G72 lub cav txuag tus tswv ntawm cov nqi ntxiv. Yog tias cov tswv ntawm 6G71 yuav tsum tau mus rau qhov chaw pabcuam txhua 15 txhiab kis lus mev los kho cov li qub, tom qab ntawd nrog lub cav tshiab yam zoo dua.
Txawm li cas los xij, qee qhov shortcomings tseem nyob. Tshwj xeeb, qhov no cuam tshuam qhov nyuaj ntawm kev saib xyuas, overheating thiab kev puas tsuaj ntawm li qub.
- Kev tu cav yog qhov nyuaj vim qhov tseeb tias lub tog raj kheej lub taub hau tau muab faib ua ob ntu. Tsis tas li ntawd, cov tswv yim zoo li no cuam tshuam rau kev siv roj ntau ntxiv - ntau dua lubrication yog siv los tswj cov nqa hydraulic.
- Overheating ntawm lub cav muaj zog yog qhov tsis tuaj yeem nyob hauv nroog tsav tsheb, thaum lub cav tsuas yog yuav tsum tau "tso tseg", ua kom tsuas yog qis qis.
- Cov li qub khoov vim nquag plam ntawm txoj siv sij hawm. Kev hloov kho tsis siv neeg pab tshem tawm kev tawg, tab sis txoj siv hlua khi hauv qee qhov xwm txheej thiab tseem khoov lub li qub.
Lwm qhov tsis zoo ntawm 6G72 yog qhov sib txawv ntawm lub cav tsim. Qhov no cuam tshuam kev kho, txij li cov khoom siv thiab cov khoom siv ntawm cov cav sib xyaw nrog ib thiab ob lub camshafts txawv kiag li.
Nuances ntawm kev tu niaj hnub
Ib qho ntawm cov teeb meem tseem ceeb hauv kev saib xyuas lub sijhawm rau lub cav 3-liter yog hloov lub sij hawm siv tom qab 90 mais. Txawm tias ua ntej, txhua 10 txhiab kilometers, cov roj lim yuav tsum tau hloov. Kawm paub ntxiv txog kev saib xyuas tau teem tseg.
- Hloov cov pa oxygen sensors txhua 10 txhiab kilometers.
- Tshawb xyuas cov pa tso pa tawm txhua ob xyoos.
- Saib xyuas cov roj system thiab crankcase qhov cua tom qab 30 txhiab km.
- Roj teeb rov qab thiab hloov txhua 3-4 xyoos.
- Hloov cov tub yees thiab tshuaj xyuas tag nrho cov hoses thiab kev sib txuas ntawm qhov lem ntawm 30 txhiab km.
- Kev txhim kho cov roj lim tshiab thiab cov cua tshuab cua tom qab 40 txhiab km.
- Hloov cov hluav taws xob txhua txhua 30 txhiab km.
Ua haujlwm tsis zoo
Cia peb xav txog qhov nthuav dav "qhov mob" nrov ntawm 6G72, uas ua rau nws yog ib qho nruab nrab uas tsis tuaj yeem hu ua super-reliable.
- Floating ceev tom qab pib yog tshwm sim los ntawm clogging ntawm lub throttle valve thiab qaug zog ntawm lub idle regulator. Cov kev daws teeb meem suav nrog kev tu, kho thiab hloov lub sensor.
- Kev siv roj ntau ntxiv qhia tias hnav ntawm lub valve qia ntsaws ruaj ruaj thiab daig piston rings. Obviously, cov ntsiab lus no yuav tsum tau hloov.
- Knocks hauv lub cav, uas tau piav qhia los ntawm kev hnav ntawm cov pas nrig sib txuas thiab hnav ntawm hydraulic pushers. Qhov kev daws teeb meem yog hloov cov liners thiab hydraulic lifters.
Raws li cov chaw tsim khoom, kev siv roj zoo (kua roj nrog qhov ntsuas tsis qis dua AI-95) lav lub neej ntev ntawm lub cav.
Niaj hnub kho
Cov neeg tsim qauv pib tsim lub peev xwm zoo rau hauv lub cav no. Tsis muaj kev poob peev, nws tuaj yeem txhim kho 350 hp yooj yim. Nrog. Cov kws tshaj lij pom zoo kom tsis txhob hloov kho nrog turbocharging. Hauv lawv txoj kev xav, cov kev hloov hauv qab no tuaj yeem ua tau.
- Ua kom lub cheeb ntawm lub muffler thiab reflash lub electronics.
- Hloov cov qauv springs nrog lub zog ntawm 28 kg nrog cov qauv muaj zog dua uas tuaj yeem tiv taus 40 kg.
- Khau lub rooj zaum thiab nruab cov qhov loj dua.
Nco ntsoov tias atmospheric tuning yuav ua rau nws muaj peev xwm nce hwj chim los ntawm 50 litres. Nrog. Kev hloov pauv 6G72 yuav raug nqi ntau dua li kev sib pauv (lub cav hloov).
