Dab tsi yog lub luag haujlwm ntawm lub tsheb ignition coil
Lub luag haujlwm tseem ceeb ntawm lub tsheb ignition kauj yog hloov cov hluav taws xob qis uas muab los ntawm lub tsheb roj teeb rau hauv qhov hluav taws xob siab kom tsim tau cov hluav taws xob hluav taws xob uas ua rau cov roj sib xyaw hauv lub tog raj kheej lub cav. Tshwj xeeb, lub ignition coil ua haujlwm los ntawm lub hauv paus ntsiab lus ntawm electromagnetic induction, converting low-voltage hluav taws xob mus rau high-voltage hluav taws xob, kom ntseeg tau qhov kev ua hauj lwm zoo thiab du combustion ntawm lub cav.
Txoj cai ua haujlwm
Lub ignition coil ua haujlwm zoo li transformer, tab sis nws muaj nws tus kheej tshwj xeeb. Nws yog tsim los ntawm thawj kauj, theem nrab coil thiab hlau core. Thaum lub hauv paus kauj yog powered rau, qhov nce nyob rau hauv tam sim no tsim ib tug muaj zog magnetic teb nyob ib ncig ntawm nws, thiab cov tub ntxhais hlau khaws lub magnetic teb zog. Thaum lub tshuab hloov pauv disconnects thawj kauj Circuit Court, lub magnetic teb ntawm thawj coil decays sai, thiab theem nrab coil senses ib tug high voltage. Qhov nrawm ntawm qhov sib nqus ntawm cov kauj ruam tseem ceeb ploj mus, qhov ntau dua tam sim no ntawm kev sib txuas tam sim no, thiab qhov ntau dua qhov sib piv ntawm ob lub coils, qhov siab dua qhov voltage induced los ntawm lub thib ob kauj.
Kev ua haujlwm tsis raug thiab cuam tshuam
Yog hais tias lub ignition coil yog faulty, nws yuav ua rau lub txim hluav taws xob tsis ignite ib txwm, uas yuav cuam tshuam rau kev ua haujlwm ntawm lub cav. Qhov kev ua tau zoo tshwj xeeb suav nrog lub tsheb tsis tuaj yeem pib ib txwm, qhov nrawm nrawm tsis ruaj khov, qhov nrawm nrawm tsis zoo, thiab lub teeb ua txhaum yog nyob rau. Tsis tas li ntawd, lub ignition coil yog tawg kuj yuav ua rau lub cav vibration, tsis muaj zog acceleration, high-qib tsis mus txog cov tsos mob.
Cov lus qhia txog kev tu thiab tu
Txij li thaum lub ignition coil plays lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm lub cav tsheb, nws cov kev saib xyuas thiab kev saib xyuas kuj tseem ceeb heev. Tsis txhob tso lub ignition coil mus rau qhov kub thiab txias kom tsis txhob muaj kev puas tsuaj rau cov khoom siv hluav taws xob thiab hluav taws xob. Yog tias qhov hluav taws xob hluav taws xob tau pom tias muaj teeb meem, nws yuav tsum tau hloov lub sijhawm kom ntseeg tau tias lub cav ua haujlwm li qub.
Thaum lub ignition coil ntawm lub tsheb puas lawm, cov kauj ruam hauv qab no yuav tsum tau ua los kho thiab hloov:
Txheeb xyuas qhov voltage thiab tsis kam: Ua ntej, tig qhov hluav taws xob hloov mus rau ON, tshem tawm cov hlua hluav taws xob txuas ntawm lub tshuab hluav taws xob hluav taws xob, thiab siv lub tshuab hluav taws xob los xyuas seb puas muaj li 12V voltage ntawm tus pin No.3 ntawm qhov txuas thiab hauv av cable. . Yog tias tsis muaj qhov hluav taws xob, xyuas cov kab txuas. Nyob rau tib lub sijhawm, xyuas seb puas muaj qhov luv luv lossis qhib Circuit Court ntawm tus pin No. 1 thiab tus pin No. 5 ntawm ECU thiab tus pin No. 2 ntawm ECU. Tsis tas li ntawd, ntsuas seb tus thawj coil tsis kam ntawm lub sensor yog li ntawm 0.9Ω thiab qhov thib ob coil kuj yog li 14.5kΩ. Yog tias tsis muaj qhov tseem ceeb no, xav txog kev hloov lub ignition coil. cov
Kev Tshawb Nrhiav waveform : Lub oscilloscope yog siv los xyuas seb puas yog qhov thib ob ignition waveform ntawm high voltage kab ntawm lub ignition system nyob rau hauv ib txwm lub xeev. Yog hais tias lub waveform yog txawv txav, lub ignition coil yuav tsum tau hloov.
Hloov lub ignition coil : Thaum hloov lub ignition coil, nco ntsoov xaiv lub kauj uas phim tus qauv, thiab tsis txhob yuam kev xav tias tag nrho cov coils ntawm tib voltage yog universal. Tsis tas li ntawd, kev tiv thaiv txhua hnub kuj tseem ceeb heev, xws li kev tshuaj xyuas tsis tu ncua, tu thiab nruj ntawm cov kab sib txuas kom tsis txhob muaj luv luv Circuit Court lossis teeb meem hauv av; Kho lub cav ua haujlwm kom tsis txhob muaj hluav taws xob ntau dhau; Thiab tsis txhob nthuav tawm cov hluav taws xob hluav taws xob kom sov lossis av noo ntau dhau. cov
Ua rau ignition coil puas yuav muaj xws li:
Kev laus: Lub ignition coil yuav maj mam muaj hnub nyoog thaum siv, ua rau txo qis kev ua haujlwm.
overheat : ua hauj lwm ntawm qhov kub siab rau lub sij hawm ntev yuav ua rau muaj kev puas tsuaj rau lub ignition coil.
Cov av noo ib puag ncig: cov av noo tuaj yeem ua rau corrosion ntawm cov khoom sab hauv ntawm lub ignition coil, cuam tshuam rau nws txoj haujlwm ib txwm muaj.
Cov teeb meem hauv Circuit Court : Ib qho luv luv lossis qhib Circuit Court kuj tseem tuaj yeem ua rau lub teeb hluav taws xob puas.
Kev tiv thaiv kev tiv thaiv: Txheeb xyuas cov xwm txheej ntawm cov hluav taws xob hluav taws xob tsis tu ncua, ua kom nws qhov chaw ua haujlwm qhuav, tsis txhob muaj cua sov, thiab tsis tu ncua tu thiab ua kom cov kab txuas txuas ntxiv mus rau nws txoj haujlwm.
