Tej zaum, txhua tus neeg tsav tsheb tau nkag mus rau qhov xwm txheej zoo li no thaum muaj ib hnub zoo, tom qab tig tus yuam sij hluav taws xob, nws "tus phooj ywg hlau" tsis kam pib. Oddly txaus, tab sis yog vim li cas rau qhov no yuav tsis tau tsuas yog ib tug cog roj teeb los yog ib tug burnt oob khab, tab sis kuj yog ib tug crankshaft sensor. Yog hais tias nws lub cev tau deformed los yog tag nrho cov qauv tau tsiv ob peb millimeters mus rau sab, qhov no yuav tsum tau hloov.

Thiab thaum koj cov neeg nyob ze lub chaw nres tsheb qhia rau koj tias kev hloov lub ntsiab lus no yog kev ua haujlwm nyuaj uas yuav tsum tau siv cov cuab yeej kim tshwj xeeb, tsis txhob ntseeg cov lus no. Koj tuaj yeem hloov lub crankshaft sensor koj tus kheej. Ntxiv mus, los ntawm kev ua haujlwm zoo li no, koj txuag tau nyiaj ntau ntawm cov chaw pabcuam thiab tib lub sijhawm tau txais kev paub hauv cheeb tsam no. Yog li ntawv hnub no yuav yog ib qho tseem ceeb rau txhua tus neeg tsav tsheb.

Vim li cas lub crankshaft sensor tsis ua haujlwm?

Raws li kev nyeem ntawm ntu no, lub tshuab txhaj tshuaj synchronizes kev ua haujlwm ntawm cov injectors thiab ignition. Yog li ntawd, kev txhaj tshuaj tsis tuaj yeem tsis muaj qhov no. ThiabThaum lub crankshaft sensor nres ua haujlwm, kev cuam tshuam pib hauv lub cav. Yog li ntawd, tsis muaj lub tsheb niaj hnub tuaj yeem ua yam tsis muaj qhov khoom me me no. Thiab txhawm rau tiv thaiv qhov ua haujlwm tsis zoo no, koj yuav tsum tsis tu ncua xyuas qhov xwm txheej ntawm lub sensor. Tab sis thaum cov tsos mob pib tig mus rau qhov tseeb, tus neeg tsav tsheb tsis muaj kev xaiv tab sis yuav tsum hloov nws sai sai.

Yuav ua li cas tshem lub crankshaft sensor?

Peb ceeb toom tam sim ntawd tias cov txheej txheem no tuaj yeem ua tau yam tsis muaj kev nqa tshwj xeeb. Yog li, cia peb mus ua haujlwm. Ua ntej, unscrew lub sensor mounting bolts uas txuas nws mus rau lub gearbox. Qhov tseeb, txhawm rau tshem tawm qhov xav tau qhov seem, peb xav tau theem no xwb. Tab sis txij li qhov no nyob rau hauv ib qho chaw nkag tsis tau (yuav luag nyob hauv qab), peb yuav tau tawm hws ntau. Txhawm rau ua haujlwm, peb xav tau cov hlua txuas ntxiv, 11 mm wrench thiab, tau kawg, teeb pom kev zoo. Nws yog ib qho tseem ceeb uas qhov ntev ntawm thawj feem yog li 80-90 centimeters. Yog tias koj muaj cov cuab yeej no, tshem tawm cov bolts. Tab sis ua ntej koj tshem lub crankshaft sensor, xyuam xim tshwj xeeb rau cov roj hmab ncoo. Yog tias yav tom ntej nws tsis zoo los yog nws qhov sib txawv tsawg kawg yog 1 millimeter, tag nrho cov kev nyeem ntawm cov ntsuas ntsuas yuav tsis raug, thiab, raws li, lub cav yuav ua haujlwm tsis tu ncua. Nws yog qhov zoo tshaj plaws los kos cov ntsiab lus no thiab muab tso rau hauv ib qho chaw sib cais. Tag nrho cov txheej txheem ntawm dismantling ib feem, bolts thiab spacer yuav tsum tau ua nrog kev saib xyuas zoo. Cov khoom no tsis nyiam tuav ntxhib.

Tom ntej no, peb muab lub crankshaft sensor tshiab thiab mount nws rau qhov qub. Thaum lub sij hawm installation, lub caij no yuav tsum tau txo qis los ntawm tag nrho cov cav compartment thiaj li tsis mus ntes cov connector los ntawm cov ntsia tau los ntawm saum toj no. Ces tsis txhob hnov qab txog lub gasket. Peb ua tib zoo mount nws thiab xyuas qhov tseeb ntawm cov qauv. Nws yog ib qho tseem ceeb uas qhov sib txawv ntawm nws thiab lub sensor yog tsawg los yog tsis muaj kiag li. Tom qab ntawd, peb txuas cov xov hlau mus rau ib feem, txuas tag nrho cov connectors thiab pib lub ignition. Yog tias koj ua txhua yam zoo, nco ntsoov - lub cav yuav pib nrog ib nrab tig.
