Muaj peev xwm ua haujlwm tsis zoo 4g15
Lub cav 4g15 thiab nws cov analogues muaj ib daim ntawv teev npe ntawm kev ua haujlwm tsis zoo - qhov yuav tshwm sim. Piv txwv li, yog tias kev sib pauv yog tsim los ntawm 4g15 rau 4g93t, ces daim ntawv teev cov teeb meem tshwm sim yuav nyob twj ywm. Qhov ua rau muaj qhov tshwm sim thiab cov kev xaiv kom tshem tawm lawv yog qhov raug thiab tsis tseem ceeb. Ntau yam teeb meem tuaj yeem tiv thaiv ua ntej los ntawm kev kuaj mob raws sij hawm, hloov cov roj lim tam sim, thiab kuaj xyuas compression.
Lub ntsiab hom cav malfunctions 4g15:
- qhia cov ntaub ntawv ntsuas kub tsis raug;
- tsis ua hauj lwm ntawm 4g15 hloov, distributor;
- poob idling;

- Nyuaj pib lub cav;
- nce roj noj;
- teeb meem thaum hloov lub zog (lub flywheel yuav tsum tau hloov).
Feem ntau ib qho kev hloov kho throttle tsuas yog xav tau. Qhov no yuav tshem tawm qhov nyuaj ntawm kev pib lub cav. Feem ntau muaj teeb meem nrog lub ignition, pib. Yog hais tias muaj teeb meem nrog pib lub cav, ces ua ntej ntawm tag nrho cov xyuas lub ignition kauj. Thaum qhov tsis ua haujlwm nrawm ploj, qhov ua rau tuaj yeem ua tau ntau yam, tab sis feem ntau nws yog qhov tsis siv neeg ceev sensor.
Nws tsis yog qhov tsis yooj yim rau qhov throttle txoj hauj lwm sensor ua tsis tiav. Tus nqi ntawm kev hloov nws yog tsawg - ib yam li qhov tshiab nws tus kheej. Kev yuav khoom kho rau 4g15 chav tsev yuav tsis nyuaj; txhua qhov chaw muaj rau qhib muag. Cov teeb meem feem ntau tshwm sim nrog kev siv roj ntau ntxiv - kev ua xyem xyav feem ntau poob rau ntawm lambda sojntsuam, vim nws yog lub sensor uas yog lub luag haujlwm kom tau txais cov ntaub ntawv hais txog cov seem ntawm cov pa oxygen hauv cov pa pa.
Yog tias lub tsheb tsuas tsis pib, koj yuav tsum paub koj tus kheej nrog cov lej yuam kev. Nws yog feem ntau yuav tsum tau kho lub torque ntawm bolts ntawm lub tog raj kheej taub hau. Tsis yog ntau zaus, tab sis nws tshwm sim tias lub valve npog gasket leaks - uas ua rau cov roj nkag mus rau hauv qhov dej tswm ciab. Nws yog ib qho tseem ceeb uas yuav tsum tau saib xyuas lub cav tas li kom tsis muaj zog nruj ntawm cov pob qij txha - kev tshem tawm cov backlash yuav tsum tshwm sim raws sijhawm.
Txij nkawm zoo
Cov npe ntawm cov khoom seem uas yuav xav tau rau kev kho yog qhov dav heev, tab sis muaj - uas yog vim li cas rau kev tswj xyuas siab ntawm cov tsheb nruab nrog 4g15 thiab analogues. Kev xaiv ntawm qhov chaw yog ua raws nraim los ntawm lub cav naj npawb. Txhawm rau khaws cov sensors, tus xa khoom, lub crankshaft lossis lub twj tso kua mis siab, koj yuav tsum paub ib qho. Pom nws tsis yooj yim li, nws nyob rau sab xis ntawm cov yeeb nkab tawm ntawm lub tshuab hluav taws xob (daim duab qhia qhov chaw uas tus lej tsav tsheb nyob):
Tsis tas li ntawd, kev tshawb nrhiav cov khoom seem tuaj yeem ua tiav los ntawm cov ntawv teev npe, siv tus lej xov tooj. Nws tsim nyog paub koj tus kheej ua ntej nrog qhov chaw ntawm cov sensors thiab lwm qhov chaw uas feem ntau tsis ua haujlwm (feem ntau cov twj tso kua mis roj, twj tso kua mis, ntsuas kub, distributor). Cov roj siab sensor yuav tsum tau kuaj xyuas ntau zaus dua li lwm tus - vim tias cov roj ntsha tsis txaus, scuffing ntawm lub pistons tuaj yeem ua tau. Koj yuav tsum paub tias lub cav naj npawb nyob qhov twg - vim nws yuav tsum tau sau npe rau lub tsheb.
Nws yog tsim nyog sau cia lub ntsiab zoo ntawm kev khiav hauj lwm lub cav 4g15:
- valve clearances yuav tsum tau kho kuj tsis tshua muaj;
- Hloov ntau yam tsis tas yuav mus ntsib lub chaw pabcuam tsheb; txhua yam tuaj yeem kho tau hauv lub chaw nres tsheb (hloov lub ignition coil, tso pa tawm, roj twj tso kua mis);
- Cov txheej txheem kho yog qhov yooj yim heev los ntawm kev pom zoo, yog li kev pabcuam lub tsheb txawm tias muaj kev sib tw siab yuav pheej yig (kho cov khoom siv hydraulic, camshaft zog);
- tus nqi ntawm cov khoom seem yog tsawg - piv txwv li, kev yuav khoom valve qia ntsaws ruaj ruaj los yog lub siab sensor nyob rau hauv lub intake manifold yuav raug nqi ntau pua rubles;
- Kev kuaj xyuas DPTZ tuaj yeem nqa tawm hauv txhua qhov chaw pabcuam, kho qhov ntsuas qhov ntsuas qhov ntsuas tau tuaj yeem ua tiav hauv chav nres tsheb;
- Kev kho ntawm lub oob khab solenoid relay tsis tshua xav tau - uas yooj yim rau kev daws teeb meem yog tias lub cav tsis tuaj yeem pib.
Qhov no yog li cas daim duab ntawm dips nyob rau hauv qab ntawm lub 4g15 cav zoo li:
Yog hais tias lub tsheb tsis pib, ces tej zaum yuav muaj teeb meem nyob rau hauv lub ignition Circuit Court (nws yuav pw nyob rau hauv lub starter, lub intake manifold yuav clogged). Qhov Circuit Court no yooj yim hauv kev tsim, tab sis koj yuav tsum ua tib zoo tshuaj xyuas tag nrho cov khoom kom pom qhov ua txhaum. Yog hais tias pib teeb meem tshwm sim nyob rau hauv qis-zero kub, ces lub txim plugs feem ntau yuav dej nyab. Kev siv lub cav 4g15 ntawm qhov kub thiab txias qis dua xoom yog teeb meem. Koj yuav tsum tau ua tib zoo saib xyuas qhov hluav taws xob hauv cov hluav taws xob thaiv hluav taws xob - yog tias tsim nyog, tshem lub tshuab hluav taws xob thiab hloov nws.
Lub ntsiab bearings yog, qhov tseeb, bearings rau kev sib txuas pas nrig (tsim raws li crankshaft bearings). Nws yog ib qho tsim nyog yuav tsum ua tib zoo saib xyuas lawv cov hnav. Kev kho piston feem ntau yuav tsum tau ua vim cov roj tsis zoo. Floating speeds kuj tuaj yeem yog qhov tshwm sim ntawm cov roj nplua nyeem tsis zoo. Tsis tas li ntawd, tej zaum yuav muaj lwm yam laj thawj rau qhov no, piv txwv li, kev siv cov khoom siv kho los ntawm cov chaw tsim khoom tsis paub.
Yuav siv roj dab tsi hauv lub cav?
Kev xaiv zoo ntawm cov roj cav yog tus yuam sij rau qhov tsis muaj teeb meem hauv kev ua haujlwm. Lubricants cuam tshuam rau ntau yam kev siv tsheb. Nyob rau hauv xyoo tas los no, raws li cov neeg siv kev txheeb xyuas, Liqui-Molly 5W30 Cov roj tshwj xeeb AA tau ua pov thawj nws tus kheej kom zoo. Nws yog tsim rau American thiab Asian engines. Ntxiv mus, nws tso cai rau peb los daws qhov teeb meem tseem ceeb hauv kev ua haujlwm ntawm 4g15 - qhov nyuaj ntawm kev pib ntawm subzero kub.
Raws li kev txheeb xyuas, tso tawm txawm tias ntawm -350 Nrog tsis yooj yim. Tsis tas li ntawd, cov roj no tuaj yeem txo qhov kev siv ntawm lubricants. Thaum lub sij hawm kev ntsuam xyuas, noj ib 10 km ntawm saum toj no-zero kub tsuas yog 000 g. Nws yog ib tug zoo qhia, vim hais tias raws li cov neeg tsim khoom siv, qhov nruab nrab roj noj yog 300 liter rau txhua txhua 1 km.
Qhov kev daws teeb meem zoo tshaj plaws yog siv cov roj hluavtaws tag nrho, kev siv cov ntxhia sib txuas yog contraindicated rau cov cav no. Kev siv cov roj hluavtaws "ib txwm" los ntawm Mitsubishi muaj txiaj ntsig zoo rau kev ua haujlwm. Nws cov nqi kuj tsawg, thaum nws kam rau ua tiav nrog rau cov kev xav tau ntawm lub cav - uas muaj txiaj ntsig zoo rau kev siv roj av thiab kev ua haujlwm ntev (300 txhiab km kuj yog "kho" ntawm cov roj cav).
Valvoline 5W40 kuj tseem siv ntau zaus hauv cov cav no. Qhov zoo ntawm qhov no tsuas yog txo qis ntawm oxidation. Txawm hais tias siv lub tsheb hnyav hauv "lub nroog" hom, cov roj no tuaj yeem yooj yim "tus neeg saib xyuas" 10-12 txhiab km thiab tsis poob nws cov khoom siv lubricating thiab tu. Thaum xaiv cov roj, nws yog ib qho tseem ceeb uas yuav tau xav txog qhov ntsuas kub ntawm lub tsheb.
Niaj hnub no, 4g15 cav yog qhov tsawg heev, tab sis qee cov qauv tau nruab nrog kev hloov kho sib sib zog nqus. Chav tsev yog qhov txawv los ntawm kev ruaj ntseg zoo thiab tsis muaj kev cia siab.
