Lub sensor camshaft ntawm lub tsheb yog dab tsi
Youdaoplaceholder0 Camshaft Position Sensor (CPS) yog ib lub cuab yeej siv los sau cov teeb liab qhov chaw camshaft thiab feem ntau yog siv rau hauv cov txheej txheem tswj cav. Nws cov haujlwm tseem ceeb suav nrog kev nkag mus rau cov teeb liab qhov chaw camshaft rau chav tswj hluav taws xob (ECU) los txiav txim siab lub sijhawm hluav taws xob thiab roj txhaj tshuaj, pab ECU txheeb xyuas lub tog raj kheej 1 qhov chaw tuag kom ua tiav kev tswj hwm roj txhaj tshuaj, kev tswj hwm lub sijhawm hluav taws xob thiab kev tswj hwm deflameout.
Qhov chaw teeb tsa
Feem ntau, lub camshaft sensor raug ntsia rau ntawm qhov kawg ntawm lub hau camshaft, tig ncaj qha mus rau pem hauv ntej ntawm lub intake thiab exhaust camshafts. Qhov kev teeb tsa no ua kom ntseeg tau tias lub sensor ntes tau qhov teeb liab qhov chaw camshaft thiab xa mus rau ECU.
Txoj cai ua haujlwm
Cov cuab yeej ntsuas camshaft siv cov nyhuv magnetoelectric lossis Hall los ntes qhov chaw thiab qhov ceev ntawm lub camshaft. Piv txwv li, lub cuab yeej ntsuas magnetoelectric camshaft xam qhov chaw thiab qhov ceev ntawm lub camshaft los ntawm kev ntes cov kev hloov pauv ntawm cov hluav taws xob induced hauv lub sensor coil uas tsim los ntawm cov khoom siv magnetic thaum lub camshaft tig.
Txoj kev kuaj mob txhaum
Thaum koj tshuaj xyuas lub camshaft sensor, koj tuaj yeem txiav txim siab seb nws puas ua haujlwm zoo los ntawm kev tshem nws lub ntsaws thiab qhib lub qhov hluav taws xob, thiab siv lub cwj mem teeb los sim peb txoj hlua (hlua fais fab, hlua teeb liab thiab hlua av). Yog tias qhov hluav taws xob ntawm lub teeb liab txawv ntawm 0 thiab 5 volts, lub sensor ua haujlwm zoo. Txwv tsis pub, lub sensor yuav puas tsuaj.
Qhov teeb meem ntawm lub camshaft sensor ntawm lub tsheb feem ntau yog pib tsis tau zoo, khiav tsis ruaj khov, tsis nrawm, siv roj ntau, teeb liab teeb liab tsis ci tas li, thiab tej zaum yuav muaj lub cav co, khiav qeeb, tsheb kub tsis ua haujlwm, thiab lwm yam. Cov tsos mob no yog vim muaj teeb liab sensor tsis zoo, ua rau ECU tswj tsis tau lub sijhawm tua hluav taws thiab lub sijhawm txhaj roj, ua rau lub cav tsis ua haujlwm zoo.
Youdaoplaceholder0 Cov tsos mob ntawm qhov tsis ua haujlwm tseem ceeb
Youdaoplaceholder0 Qhov nyuaj hauv kev pib : Vim yog lub sijhawm teeb tsa tsis raug, nws yuav siv sijhawm ntau zaus los pib lossis tsis pib kiag li. Qee zaum, crankshaft tig rov qab thiab intake manifold backfire tau pom.
Youdaoplaceholder0 Qhov tsis ruaj khov ntawm lub cav: Lub cav co tsis zoo, qhov ceev ntawm lub cav hloov pauv, zoo li lub tog raj kheej ploj lawm, thiab hauv cov xwm txheej hnyav ua rau muaj hom limping.
Youdaoplaceholder0 Dynamic anomaly :
Kev nrawm tsis zoo thiab teb qeeb, qhov xwm txheej yuav hnyav dua 2500rpm
Muaj qhov co thaum tsav tsheb, tshwj xeeb tshaj yog thaum nrawm lossis qeeb qeeb
Youdaoplaceholder0 Kev poob qis ntawm kev lag luam :
Kev siv roj ntau ntxiv 10% -30% vim yog kev tswj qhov ntim roj txhaj tsis ua haujlwm
Cov pa phem zuj zus, cov yeeb nkab tso pa tawm feem ntau muaj pa luam yeeb dub
Youdaoplaceholder0 Ceeb Toom Txog Qhov Txhaum: Lub teeb ua txhaum ntawm lub cav tseem nyob, thiab OBD system feem ntau sau cov lej P0340-P0344 series.
Youdaoplaceholder0 Cov tsos mob thiab kev pheej hmoo ntawm cov khoom siv derivative
Youdaoplaceholder0 Lub cav kub tsis ua haujlwm: Lub cav yuav nres tam sim ntawd tom qab sov thiab yuav tsum tau rov pib dua kom khiav tau
Youdaoplaceholder0 Kev hnav ntawm cov khoom sib xyaw: Kev ua tsis tiav mus sij hawm ntev yuav ua rau cov khoom sib xyaw xws li pistons thiab phab ntsa lub tog raj kheej hnav sai dua, ua rau lub cav siv tau ntev dua
Youdaoplaceholder0 Kev pheej hmoo kev nyab xeeb : Kev cuam tshuam lossis kev txwv lub zog thaum tsav tsheb (hom limping) ua rau muaj feem yuav muaj xwm txheej tam sim ntawd .
Cov cuab yeej ntsuas qhov chaw camshaft hauv tsheb feem ntau yog ib lossis ob, nyob ntawm qhov kev teeb tsa cav
Tus naj npawb ntawm cov camshaft position sensors hauv tsheb sib txawv nyob ntawm lub cav tsim thiab kev ua haujlwm xav tau, thiab feem ntau yog muab faib ua ob qhov xwm txheej hauv qab no:
Youdaoplaceholder0 Kev teeb tsa ib leeg-sensor
Feem ntau pom muaj nyob rau hauv cov cav yooj yim lossis cov tshuab uas tsuas yog ua qhov kev tswj lub sijhawm hloov pauv ntawm cov qhov nqus dej (xws li qee cov qauv siv VVT thev naus laus zis). Cov sensors feem ntau raug ntsia rau ntawm qhov kawg ntawm lub camshaft nqus dej thiab siv los muab lub teeb liab tswj tseem ceeb rau kev tswj hluav taws xob rau ECU.
Piv txwv li: Qee cov qauv tsheb tsuas kho lub sijhawm ntawm lub qhov nqus cua los ntawm ib lub sensor xwb, thaum lub qhov nqus cua tseem ruaj khov.
Youdaoplaceholder0 Kev teeb tsa dual-sensor
Nws feem ntau pom nyob rau hauv cov tshuab uas tswj lub sijhawm hloov pauv ntawm cov qhov nqus thiab cov pa tawm tib lub sijhawm (xws li dual VVT technology). Ob lub sensors sib xws rau cov camshafts nqus thiab cov pa tawm kom ua tiav qhov kev hloov kho theem kom meej dua.
Piv txwv li, lub cav EA888 tiam thib peb tau siv ob lub sensors (ib qho rau kev nqus thiab ib qho rau kev tso pa tawm).
Youdaoplaceholder0 Cov ntsiab lus tseem ceeb:
Tus naj npawb ntawm cov sensors muaj feem cuam tshuam nrog qhov nyuaj ntawm lub cav. Cov qauv yooj yim feem ntau muaj ib lub sensor, thaum cov qauv siab lossis cov qauv ua tau zoo feem ntau yuav siv ob.
Kuj tseem hu ua "synchronous signal sensor" lossis "Cylinder discrimination and Positioning device", lub luag haujlwm tseem ceeb ntawm ob qho tib si yog xa cov ntaub ntawv theem camshaft mus rau ECU.
Qhov chaw teeb tsa yuav tsum nyob ncaj qha rau ntawm lub log teeb liab; txwv tsis pub, kev sau cov ntaub ntawv kom raug yuav tsis ua tiav.
