Crankshaft sensor: kev ua haujlwm, kev pabcuam thiab nqe
Txheem
Lub crankshaft sensor, tseem hu ua TDC sensor lossis ceev sensor, plays lub luag haujlwm tseem ceeb hauv kev ua haujlwm zoo ntawm koj lub cav. Hauv tsab xov xwm no, koj yuav pom tag nrho peb cov lus qhia rau kev saib xyuas thiab kho ntawm crankshaft sensor. Peb qhia rau koj tag nrho cov secrets, los ntawm kev khiav hauj lwm mus rau tus nqi hloov.
🚗 Lub crankshaft sensor ua haujlwm li cas?
Lub crankshaft sensor, tseem hu ua TDC sensor, txoj hauj lwm sensor, lub kaum ntse ntse sensor los yog txawm lub sensor ceev, qhia lub cav ECU txog txoj hauj lwm ntawm pistons thiaj li xam lub cav ceev thiab yog li txiav txim siab npaum li cas ntawm cov roj txhaj. Nyob rau hauv txoj kev no, TDC sensor ua kom muaj kev ua haujlwm raug ntawm koj lub cav.
Muaj ob hom crankshaft sensors:
- PMH inductive sensors: Cov crankshaft sensors no yog tsim los ntawm cov hlau nplaum thiab cov kauj uas tsim tau ib qho chaw electromagnetic. Yog li, thaum cov hniav ntawm lub cav flywheel dhau mus rau pem hauv ntej ntawm lub sensor, lawv tsim ib qho hluav taws xob teeb liab uas qhia lub computer qhov kev sib hloov ceev thiab txoj hauj lwm ntawm lub cav flywheel.
- Hall Effect PMH Sensors: cov crankshaft sensors no feem ntau siv nyob rau hauv tiam tshiab ntawm cov cav. Kev ua haujlwm zoo ib yam li inductive sensors, tshwj tsis yog tias nws tau ua hauv tshuab hluav taws xob. Tseeb tiag, thaum ib tug flywheel hniav ntawm lub cav hla mus rau pem hauv ntej ntawm lub sensor, qhov tam sim no cuam tshuam, ua rau Hall nyhuv. Hall effect sensors yog kim dua tab sis muaj tseeb dua, tshwj xeeb tshaj yog nyob rau qis revs.
👨🔧 Cov tsos mob ntawm HS crankshaft sensor yog dab tsi?
Muaj ntau cov tsos mob uas tuaj yeem ceeb toom koj tias koj lub crankshaft sensor yog faulty los yog tag nrho ntawm kev txiav txim:
- Teeb meem nrog ignition thiab pib;
- Cav uas txeeb;
- Tsis zoo li cav suab nrov;
- Rov ua dua wedges;
- Lub cav ceeb toom teeb yog qhib;
- Koj lub tsheb lub tachometer tsis ua haujlwm lawm.
Yog tias koj tau ntsib cov tsos mob no, peb xav kom koj mus rau lub chaw nres tsheb kom kuaj xyuas koj TDC sensor. Tsis txhob ncua kev kho koj lub tsheb, txwv tsis pub cov nqi tawg yuav tshwm sim.
🛠️ Yuav hloov lub crankshaft sensor li cas?
Koj puas xav hloov koj lub tsheb TDC sensor koj tus kheej? Tsis txhob txhawj, nrhiav peb cov lus qhia ua tiav tam sim no uas teev tag nrho cov kauj ruam uas koj yuav tsum tau ua los hloov lub crankshaft sensor hauv koj lub tsheb kom zoo. Txuag nyiaj ntawm kev tu tsheb los ntawm kev ua qee yam haujlwm ntawm koj tus kheej.
Cov Khoom Siv Yuav Tsum:
- Cuab Yeej
- Tshuaj pleev thaiv hnub
- Hnab looj tes tiv thaiv
- txuas
- Свеча
Kauj Ruam 1: Nias lub tsheb
Pib los ntawm kev siv lub jack los tso lub tsheb rau ntawm qhov kev txhawb nqa jack. Xyuas kom lub tsheb nyob ntawm qhov chaw kom tsis txhob muaj teeb meem thaum ua haujlwm.
Kauj Ruam 2: Tshem tawm cov khoom siv hluav taws xob
Qhib lub hood thiab nrhiav TDC sensor hluav taws xob txuas ntawm lub cav. Nws feem ntau yog nyob rau ntawm lub davhlau ya nyob twg thaiv ntawm ib sab ntawm lub kiv cua lossis lub qhov dej txias. Thaum pom qhov tseeb connector, unplug nws. Yog tias tsis ntseeg, tsis txhob yig mus sab laj nrog koj lub tsheb cov ntaub ntawv qhia kev.
Kauj ruam 3: Tshem lub crankshaft sensor.
Tom qab ntawd nce mus rau hauv qab lub tsheb thiab unscrew lub crankshaft sensor mounting ntsia liaj qhov rooj. Tom qab ntawd koj tuaj yeem tshem tawm TDC sensor ntawm nws qhov chaw.
Kauj ruam 4: Nruab ib lub crankshaft sensor tshiab.
Tom qab ntawd sib sau ua ke tus tshiab crankshaft sensor nyob rau hauv rov qab kev txiav txim.
Ceeb toom: Qhov chaw ntawm TDC sensor yuav txawv nyob ntawm koj lub tsheb qauv. Tseeb, ntawm qee cov qauv, koj yuav tsum mus dhau ntawm lub hood thiab disassemble qee yam khoom kom tau txais kev nkag mus rau crankshaft sensor.
💰 Tus nqi npaum li cas los hloov lub crankshaft sensor?
Qhov nruab nrab, cia siab tias € 150 txog € 200 los hloov TDC sensor hauv koj lub chaw nres tsheb. Ib feem ntawm nws tus kheej raug nqi ib ncig ntawm 65 euros, tab sis lub sijhawm ua haujlwm nrawm nrawm rau daim nqi vim nws yog kev cuam tshuam ntev thiab nyuaj. Thov nco ntsoov tias tus nqi ntawm lub crankshaft sensor txawv heev nyob ntawm seb hom sensor (inductive, Hall effect, thiab lwm yam). Xav tias dawb los sib piv cov kev pabcuam tsheb zoo tshaj plaws nyob ze koj los txiav txim qhov pheej yig thiab zoo tshaj plaws los ntawm lwm tus neeg siv internet.
Nrog Vroomly, thaum kawg koj tuaj yeem txuag tau ntau ntawm kev saib xyuas thiab hloov koj lub crankshaft sensor. Nyob rau hauv ob peb clicks, koj yuav tau nkag mus rau tag nrho cov muab los ntawm cov kev pab cuam tsheb zoo tshaj plaws nyob rau hauv koj cheeb tsam. Tom qab ntawd koj tsuas yog yuav tsum tau teem sijhawm nrog tus neeg twg uas koj nyiam rau tus nqi, kev tshuaj xyuas cov neeg siv khoom thiab qhov chaw.
