Ua luam dej ceev rau Vaz-2114 - qhov ua rau thiab cov kev daws

Qhov teeb meem nrog floating lem yuav tshwm sim nyob rau hauv txhua lub tsheb tswv. Thiab nws tsis muaj nqi, nws yog lub cav carburetor los yog injector. Yog vim li cas ntse jumps ntawm revolutions yuav ua tau ib tug heev heev. Thiab niaj hnub no, peb xav txog qhov teeb meem no nyob qhov twg turnovers ntab rau lub Vaz-2114, raws li tau zoo raws li yuav ua li cas los daws kom tau qhov teeb meem no.

lub cav ECU

Heev feem ntau qhov ua rau ntawm qhov teeb meem yog nws yog tus "hlwb" ntawm lub tsheb, uas yog, qhov hluav taws xob tswj tsev. Nyob rau hauv cov ntaub ntawv ntawm breakage ntawm ib tug sensor uas yog lub luag hauj lwm rau qhov tseeb lag luam ntawm lub internal combustion engine, los yog lub computer yuav tsis muab ib tug meej thiab tseeb hais kom system, uas ua rau yus mus rau lub tsos ntawm floating ceev thaum tob tob rau hauv huab cua sab. Nyob rau hauv cov ntaub ntawv no, mus rau lub chaw muab kev pab thiab ua ECU diagnostics raws li lawv tus kheej tsis muaj tshwj xeeb cov cuab yeej thiab pab kiag li lawm yog tsis yog tau los mus txiav txim qhov yuam kev lis dej num thiab troubleshooting.

Sensors thiab lawv tsis ua hauj lwm

Ntawm cov hoob kawm, yog hais tias tus computer muab tawm tsis ncaj ncees lawm pab neeg, nws tsis txhais hais tias nws yog tawm ntawm kev txiav txim. Ua kev puas tsuaj yuav tsum tau nyob rau hauv cov nram qab no sensors:

1. IAC (regulator ntawm idling).
2. DMRV (MAF sensor).
3. EGR.

Nws yog vim hais tias cov khoom no feem ntau ntab lem rau Vaz-2114.

Yog hais tias tag nrho cov ntsiab yog ua hauj lwm kom zoo, koj yuav tsum tshawb nrhiav qhov muaj plugs thiab xyuas qhov mob ntawm lub cua lim. Los ntawm txoj kev, tej zaum qhov ua rau ntawm floating ceev yuav tsis yog tus sensor nws tus kheej, thiab nws cov hluav taws xob thaiv.

Yog vim li cas ua luam dej ceev rau Vaz-2114? mob ntawm IAC

Ua ntej ntawm tag nrho cov peb mus saib lub IAC sojntsuam. Nyob rau tsheb ntawm domestic ntau lawm nws yog mounted rau lub throttle lub cev nyob ze ntawm lub throttle txoj hauj lwm sensor nyob rau hauv ob mounting screws. Mus xyuas yog hais tias nws ua hauj lwm, peb yuav tsum tau npaj ib tug multimeter. Ua ntej, tig tua lub ignition, ces disconnect tus connector nrog cov hlau los ntawm lub sensor thiab los ntawm txoj kev peb apparatus yog ntsuas lub theem ntawm kuj ntawm lub maub los hu. Nyob rau hauv tej yam kev mob, qhov no tus nqi yog 40-80 ohms. Yog hais tias koj tau txais readings yog tsis muaj tseeb, feem ntau yuav, lub regulator tau tuaj mus rau ib tug txhaum. Nyob rau hauv cov ntaub ntawv no, nws yuav tsum tau hloov.

DMRV

Tom ntej no nyob rau hauv kab rau ntawm daim tshev - loj pa txaus sensor. Nws yog ib feem ntawm yog vim li cas vim li cas cov ntab puv ntawm cov kev mus. Rau nws, peb tseem yuav siv ib tug multimeter xeem. Ntawm no yog peb ntsuas lub voltage ntawm ob terminals - connectors DFID, uas yog haum rau lub ntsuab thiab daj nyob ntawm tej. Thaum nqa tawm diagnostic engine yuav tsum tau switched tawm thiab tiv cav tseb yog muab rau. Lub cav yuav tsum qhia ib tug nqi ntawm 0,999 mus 1.02 V. Yog hais tias lub readings tsis nrhiav pov thawj nyob qhov txhia qhov muaj yog ib tug txhaum DFID.

EGR valve

Qhov no ntaus ntawv yog ib tug sensor EGR. EGR valve directs ib feem ntawm cov gases nyob rau hauv lub combustion chamber, li no kom yuav ntawm ua kom tiav combustion thiab thiaj li kom txhob muaj cov theem ntawm tshuaj lom emissions rau sab nraum cua. By tsim, no piece yog yooj yim heev, tab sis ntau heev nrog nws teeb meem. Yog hais tias koj tsis tseg ntxuav lub valve lub rooj zaum thiab qhov chaw ntawm tsaws, tsis ntev koj yeej yuav tau txais tsis ruaj tsis khov lub cev muaj zog lub lag luam. Qhov no yog lub ntsiab yog vim li cas vim li cas lub cav ceev kom ntab rau lub Vaz-2114. Yog hais tias koj tsis tau ntxuav qhov khoom, siv aerosol tu carburetors yuav tsum ua tib zoo kho lub kab mob cheeb tsam. Nyob rau hauv cov ntaub ntawv no, tsis txhob cia cov ntaub ntawv uas tau txais nyob rau hauv lub valve diaphragm.

Yog vim li cas ntab lub khanpuletauj ntawm lub cav tsheb tshuab idling?

Vaz-2114 "Samara" nrog carbureted nrog combustion engine no kuj tsis yog tiv thaiv kab mob rau tej teeb meem. Yuav ua li cas tshwm sim yog, qhov zoo ces, tsis txhob niaj hnub, tab sis tseem. Lub ntsiab yog vim li cas yog faulty los yog wrongly tom carburetor nws tus kheej. Tsis tas li ntawd floating ceev tej zaum yuav tshwm sim los ntawm cua xuas los yog ib tug puas solenoid valve XX. Nyob rau hauv tas li ntawd, nws yog tsim nyog los xyuas cov huab cua lim nyob rau hauv muaj ib tug deposit.

Tab sis feem ntau ntawm cov floating turnovers tshwm sim vim hais tias ntawm tsis yog carburetor haum. Nyob rau hauv cov ntaub ntawv no, koj yuav tsum tau kho nws kom zoo los ntawm kev xa cov screws zoo thiab muaj nuj nqis ntawm cov roj.

Raws li rau lub solenoid valve, nws yog ua tau rau kev tshawb nrhiav tsis tau tshem ntawm nws lub hwj huam qaum. Txaus nrog lub ignition qaum touch hu rau lub valve - ib tug nias yuav tsum tshwm sim sai sai. Yog hais tias tsis tau, koj yuav tau sim kov lub hu hlau, uas yog kev cob cog rua rau lub zoo davhlau ya nyob twg rau lub roj teeb. Yog hais tias thiab tom qab ntawd koj yuav tsis hnov nias, ces feem ntau yuav, lub valve tuaj rau malfunction. Yuav kom kho nws, koj yuav tsum qhib nws thiab ntxuav lub nozzle.

Yog li ntawd, peb pom tawm yog vim li cas cov ntab puv Vaz-2114 thiab yuav ua li cas los daws qhov teeb meem no nyob ntawm seb hom kev txhaum.
