Thaum twg los hloov PMH sensor?
Txheem
Lub TDC sensor yog qhov hluav taws xob ntawm koj lub tsheb uas tso cai rau koj lub cav pib. Yog tias nws tsis ua haujlwm lawm, koj yuav tau mus rau lub chaw nres tsheb kom kho tam sim ntawd. Yog tias koj muaj lus nug txog kev ua haujlwm thiab kev saib xyuas ntawm koj lub PMH sensor, tsab xov xwm no yog rau koj!
🚗 Lub luag haujlwm ntawm PMH sensor yog dab tsi?
Lub TDC (los yog Top Dead Center) sensor yog ib qho hluav taws xob tivthaiv hu ua crankshaft sensor lossis ceev sensor. Nws nyob ntawm lub crankshaft thiab flywheel.
Qhov no tso cai rau lub cav ceev yuav raug xam thiab yog li cov roj txhaj tshuaj yuav tsum yoog.
Qhov no sensor muaj ib tug dual muaj nuj nqi: nws qhia lub cav tswj lub computer txog txoj hauj lwm ntawm lub piston thiab qhov ceev ntawm kev sib hloov ntawm lub crankshaft.
Thaum kawg, peb nco ntsoov tias qhov ntsuas no siv tsawg dua thiab siv tau rau cov tsheb niaj hnub; nws tau maj mam hloov los ntawm cov qauv nrog Hall effect.
🔍 TDC sensor nyob qhov twg?
Lub TDC sensor, tseem hu ua crankshaft sensor, nyob ntawm theem ntawm lub cav flywheel. Qhov no tso cai rau lub cim cim ntawm lub cav flywheel thiab yog li sib txuas lus txoj hauj lwm ntawm tag nrho cov pistons uas ua rau lub cav mus rau lub computer.
️ ib TDC sensor kav ntev npaum li cas?
Lub neej ntev ntawm TDC sensor yog qhov nyuaj los txiav txim siab. Nws tsis tuaj yeem hloov pauv hauv lub neej ntawm lub tsheb, ib yam li nws tuaj yeem ua tsis tiav tom qab ob peb kaum txhiab kilometers.
🚘 Yuav kuaj TDC sensor li cas?
Nov yog cov tsos mob uas qhia tias TDC sensor nyob hauv HS xeev:
- Ua tsis tau lossis pib nyuaj;
- Cav jerks thiab knocks;
- Ntau lub khw muag khoom tsis raws sijhawm thaum tsav tsheb ntawm kev txo qis;
- Lub tachometer tsis qhia cov ntaub ntawv raug lawm.
Hmoov tsis zoo, feem ntau nws tsis tuaj yeem pib lub cav vim muaj kev ua haujlwm tsis zoo ntawm TDC sensor. Lub cav yuav tsis pib.
Cov paib qub no tuaj yeem qhia lwm yam teeb meem, yog li nug tus kws kho tsheb los tshuaj xyuas koj lub tsheb kom tsis txhob dhia mus rau qhov xaus.
🔧 Kuv yuav paub li cas yog kuv TDC sensor ua haujlwm?
Txhawm rau kom paub tseeb tias koj lub PMH sensor ua haujlwm zoo, koj yuav tsum tau sim nws qhov kev tiv thaiv nrog multimeter. Peb piav qhia yuav ua li cas ntawm no!
Cov ntaub ntawv uas yuav tsum tau: multimeter, adjustable ciaj ntswj.
Kauj Ruam 1. Disassemble PMH sensor
Ua ntej, koj yuav tsum disassemble PMH sensor los kuaj nws. Yuav kom disassemble nws, unscrew lub screws uas tuav nws nyob rau hauv qhov chaw, ces disconnect lub sensor los ntawm connectors thiab tshem tawm ntawm lub rooj.
Kauj Ruam 2. Saib xyuas lub sensor
Ua ntej, soj ntsuam koj qhov ntsuas thiab ua kom pom cov khoom muag sai. Xyuas kom tseeb tias koj lub sensor tsis dhau clogged, tom qab ntawd xyuas kom cov hlua khi tsis raug txiav (tshwj xeeb, nws tuaj yeem ua rau luv luv) thiab qhov sib txawv ntawm huab cua tsis puas. Yog tias txhua yam zoo, qhov teeb meem tsis yog nrog lub sensor puas, yog li koj tuaj yeem tshawb xyuas nws nrog multimeter.
Kauj Ruam 3. Txheeb xyuas qhov tseeb
Txhawm rau txheeb xyuas qhov txuas ntxiv ntawm lub sensor, muab lub multimeter nyob rau hauv hom kev ntsuas txuas ntxiv. Cov kauj ruam no yuav kuaj xyuas qhov luv luv ntawm hauv av thiab cov zis sensor. Pib los ntawm kev ntxig ib kawg ntawm lub multimeter mus rau hauv ib qho ntawm lub davhlau ya nyob twg qhov thiab lwm qhov kawg rau hauv av. Ua tib yam rau lwm lub qhov. Yog hais tias lub multimeter qhia 1, tsis muaj kev tawg. Yog li ntawd tsis yog qhov teeb meem. Koj yuav tsum tau kuaj xyuas qhov tsis kam ntawm pmh sensor.
Kauj Ruam 4: xyuas qhov tsis kam
Txhawm rau ntsuas qhov tsis kam ntawm koj lub sensor, muab koj lub multimeter hauv ohmmeter hom. Pib los ntawm kev txheeb xyuas qhov "ib txwm" tsis kam ntawm PMH sensor ntawm lub chaw tsim khoom sensor lub vev xaib (qhia hauv ohms, piv txwv li 250 ohms). Tom qab ntawd ntxig ob qhov kawg ntawm multimeter mus rau hauv lub qhov hauv lub cev sensor.
Yog hais tias, thaum ntsuas qhov voltage, lub multimeter qhia tus nqi qis dua qhov chaw tsim khoom tus nqi pom zoo (ntawm no 250 Ohm), qhov no yog vim qhov tseeb tias PMH sensor tsis raug thiab yuav tsum tau hloov. Yog tias, ntawm qhov tod tes, tus nqi sib npaug los yog siab dua me ntsis, nws txhais tau tias koj lub PMH sensor nyob rau hauv qhov zoo thiab qhov teeb meem yog nyob rau lwm qhov. Yog li ntawd, peb qhia koj mus rau lub chaw nres tsheb kom paub meej ntxiv txog koj lub tsheb.
👨🔧 ib Yuav ua li cas yog tias kuv TDC sensor tawm ntawm kev txiav txim?
Yog tias koj TDC sensor tsis ua haujlwm, nws yuav tsum tau hloov tam sim ntawd lossis koj yuav tsis tuaj yeem rov qab los ntawm txoj kev. Txhawm rau nrhiav tus nqi zoo tshaj plaws, tau txais kev pom zoo hauv 3 nyem ntawm ib qho ntawm peb cov chaw nres tsheb uas ntseeg siab.
PMS HS sensor qhia qhov yuam kev ntawm koj lub tsheb. Tsis tuaj yeem xa cov ntaub ntawv raug rau lub cav, nws tsis tuaj yeem pib. Yog tias koj tuaj rau qhov no, tsuas muaj ib qho kev daws teeb meem xwb: ua nws. hloov.
