Roj noj nruab nrab Mitsubishi 4g54
Ib zaug nrov Mitsubishi Motors cav yog 4g54. Configuration hauv kab, plaub-lub tog raj kheej.
belongs rau Astron series. Nws tau siv nyob rau hauv kev tsim cov tsheb ntawm cov qauv nrov, piv txwv li Pajero. Siv nyob rau hauv tsheb ntawm lwm hom.
Lub cav muaj ob peb versions. Lub US version yog hu ua "Jet Valve". Lawv txawv los ntawm lub xub ntiag ntawm ib tug cais intake valve, uas muab ib tug ntxiv ntim ntawm huab cua mus rau lub combustion chamber. Cov tshuaj no leans qhov sib tov kom txo cov theem ntawm cov pa emissions nyob rau hauv tej yam kev khiav hauj lwm hom.
Lwm version ntawm Mitsubishi engine yog ECI-Multi ("Astron II"). tshwm sim hauv 1987. Lub ntsiab feature yog electronically tswj roj txhaj. ECI-Multi tau siv los tsim Mitsubishi Magna. Qhov nrov tshaj plaws version ntawm 4g54 yog carbureted. Kev tsim cov cav nrog ob-chamber carburetor pib hauv 1989. Lub carburetor muaj ib tug pib pib ntaus ntawv thiab ib tug thib ob chamber throttle pneumatic actuator. Ntawm qee cov qauv tsheb, pom muaj hluav taws xob tswj carburetor. Nyob rau hauv cov ntaub ntawv no, cov roj system yog supplemented los ntawm ib tug diaphragm-hom mechanical twj tso kua mis.
Nyob rau hauv ib qho kev sib cais, nws tsim nyog hais txog lub turbocharged version ntawm 4g54. Lub turbocharger nrog centralized roj txhaj thiab intercooler tau nruab rau ntawm Mitsubishi Starion (GSR-VR). Lub cav turbocharged tau nruab nrog lub tshuab hluav taws xob sab nraud.
Qhov zoo tshaj plaws turbocharger qauv TD06-19C tau nruab rau ntawm Pajero kev sib tw teeb tsa. Lub tsheb sib tw ntawm qhov kev hloov kho no tsis muaj rau cov neeg yuav khoom nruab nrab thiab tau siv tshwj xeeb rau kev sib tw kis las. Mitsubishi Starion tau koom nrog kev sib tw Paris-Dakar xyoo 1988.

Unit kev cia siab
Mitsubishi 4g54 yog ob-liter, txhim khu kev qha cav. Hais txog lub npe nrov "millionaire" motors. Nws nta ib qho yooj yim zog system thiab zoo tsim zoo.
Txij nkawm zoo
Mitsubishi 4g54 tsis yog lub cev muaj zog tshaj plaws. Nrhiav kom tiav cov chav nyob thiab cov khoom seem ntawm tus kheej rau nws yog qhov nyuaj me ntsis, tab sis ua tau.
Ua kom tiav cov cav, vim lawv qhov tsis tshua muaj, yog me ntsis kim dua li lawv cov counterparts.
Koj tuaj yeem txheeb xyuas qhov no ntawm ib lub vev xaib nrog cov khoom siv. Nws yog qhov ua tau kom xaj lub cav cog lus los ntawm Nyij Pooj, suav nrog los ntawm warehouses hauv Russia. Los ntawm txoj kev, qhov no yooj yim dua ua dua li nrhiav ib tus neeg, tus nqi uas feem ntau tshaj qhov txwv tsis pub.
Raws li nyob rau hauv lwm lub tsheb, nws tsis yog ib qho yooj yim rau lub oob khab. Ntxiv mus, muab lub mileage, cia txhua yam hnav tawm hauv chav tsev. Cov lamellas swell thiab yaj, lub thauj tog rau nkoj thiab txhuam yuav siv tsis tau. Qhov tseeb nthuav yog tias yuav luag tiav analogue, disassembled rau spare qhov chaw, yog ib tug iav oob khab rau 402 KENO cav. Ib chav tsev pej xeem pheej yig yog disassembled yuav luag tsis muaj teeb meem. Ib qho kev zam yog tshem tawm cov kabmob tshiab los hloov qhov qub. Rau qhov no, lub taub hau yog torn.
Tom qab ntawd, lub thauj tog rau nkoj yog luv los ntawm 2 mm. Cov ncej yog drilled los ntawm qhov kawg ntawm 1 hli los yog lub pob yog hloov nrog ib tug loj ntawm 4,5 hli.
Yog li ntawd, pheej yig qhov chaw los ntawm tus neeg pub khoom "revive" lub qub oob khab, uas ib zaug ntxiv qhia txog kev ruaj ntseg.
Feem ntau cov teeb meem nrog lub cav tsim cov saw hlau. Ntau qhov tseeb, nws qhov nro ploj los yog lub sijhawm lub sijhawm mus yuam kev (tsawg dua cov saw hlau yuav tsum tau hloov). Hauv qhov no, nws yog qhov nyuaj dua los kho qhov kev puas tsuaj thiab qhov no tsis yog qhov xav tsis thoob. Lub tensioner / damper yog ib txwm nyob rau hauv ib qho chaw nyuaj-mus txog. Nws yog ib qho tsim nyog kom tshem tawm cov grille, radiator, twj tso kua mis thiab saw npog, tshem tawm cov saw ntawm cov khoom sib npaug. Qhov sib npaug mechanism yog yuav yam tsis muaj teeb meem. Rau Mitsubishi xyaw, nws yog hu ua "Silent Shaft". Kuv zoo siab tias muaj pheej yig Lavxias teb sab thiab Ukrainian analogues ntawm xws li mechanisms.
Kev txhim kho tus neeg xa khoom hauv 4g54 sab hauv combustion engine rau cov neeg tsav tsheb tsis paub yuav ua rau muaj teeb meem ntau, txawm hais tias nws tsis txawv ntawm kev kho lwm hom tsheb. Kev ua yuam kev feem ntau yog ua rau cov hluav taws xob tsis raug lossis tsis sib xws, kev ua haujlwm tsis raug ntawm lub cav. Qhov tseem ceeb tshaj plaws yog teeb tsa tus chij raws nraim hauv nruab nrab thaum txhim kho lub distributor. Cov cim saum toj thiab qis ntawm tus xa khoom sib txuas yuav tsum tau teeb tsa qhov sib txawv, tom qab ntawd tus neeg faib khoom tau muab tso rau hauv nws qhov chaw nrog cov cim ntawm lub crankshaft thiab lub tog raj kheej taub hau.
Txij li thaum lub cav tau tso tseg tsis tau tsim rau lub sijhawm ntev, lub clutch flywheel feem ntau ua tsis tiav hauv nws. Cov kev kho zoo li no yog ib qho kim tshaj plaws.
Nrog rau kev txheeb xyuas qhov sib txuam ntawm lwm yam teeb meem, xws li kev hloov cov roj foob. Txhua gasket lossis caj pas yog yuav nrog nyuaj heev. Lawv xa mus rau qhov chaw kho yuav tsum tau tos lub lis piam. Kev hloov kho valve yog lwm cov teeb meem ntawm qhov twb "tsis hluas" 4g54. Kev lig kev cai, nyob rau hauv xws li mob nws yog yooj yim dua mus cuag ib lub chaw tshwj xeeb.
Nyob rau hauv ib qho tshwj xeeb ntawm cov teeb meem nws tsim nyog hais txog kev kho cov kab nrib pleb. Overheating ntawm lub cav feem ntau entails kho lub tog raj kheej taub hau. Cov kab nrib pleb hauv lub taub hau yog qhia los ntawm cov pa luam yeeb dawb los ntawm cov yeeb nkab tso tawm, uas qhia tias cov roj tau nkag mus rau hauv lub coolant. Tsis tas li nyob rau hauv cov xwm txheej zoo li no, npuas (cov pa pa tawm) tau pom nyob rau hauv lub tank expansion lossis radiator. Thaum parsing, roj thiab coolant leaks feem ntau kuaj pom. Nyob rau hauv tas li ntawd, lub tog raj kheej taub hau gasket yuav tsum tau.
Feem ntau, kev tshuaj xyuas ntawm Mitsubishi 4g54 yog qhov zoo. Txaus siab rau cov tswv ntawm Mitsubishi Pajero 2.6 liter yog tshwj xeeb tshaj yog muaj. Qhov tshwj xeeb kev cia siab ntawm lub cev muaj zog, qhov muaj ntawm pheej yig analogues ntawm spare qhov chaw yog hais txog. Nyob ntawm qhov xwm txheej, kev hloov pauv tsis siv neeg raug kho, bearings, gaskets thiab seals raug hloov. Tej zaum yuav muaj teeb meem nrog cov hluav taws xob, sensors thiab chain tensioner.
Roj xaiv
Hauv Mitsubishi nrog lub cav 4g54, nws raug nquahu kom sau cov roj qub Lubrolene sm-x 5w30, lub npe uas feem ntau pom hauv phau ntawv. Cov roj naj npawb: MZ320153 ( cav roj, 5w30, 1 liter), MZ320154 ( cav roj, 5w30, 4 litres). Cov roj uas tsis muaj viscosity yog qhov zoo heev rau lub cav ntawm lub hom thiab cov qauv no. Tsawg zaus, cov neeg siv xaiv cov roj nrog viscosity ntawm 0w30. Cov roj naj npawb: MZ320153 ( cav roj, 5w30, 1 liter),
MZ320154 ( cav roj, 5w30, 4 litres).
