Yuav ua li cas to taub tias lub ignition coil yog tawm ntawm kev txiav txim?

Yog tsis muaj ib qho hluav taws xob hluav taws xob, tsis yog ib lub cav hluav taws xob sab hauv yuav ua haujlwm. Raws li txoj cai, cov roj diesel qub tuaj yeem ua haujlwm yam tsis muaj hluav taws xob tag nrho, tab sis hnub ntawd yuav luag ploj mus. Niaj hnub no, txhua lub cav combustion sab hauv, ib txoj hauv kev los yog lwm qhov, yog nruab nrog cov kab ke no, thiab nws lub siab yog lub ignition coil. Ua ib qho khoom siv yooj yim txaus, lub kauj, txawm li cas los xij, tuaj yeem tsim teeb meem loj rau tus tswv lub tsheb.

Ua rau tsis ua hauj lwm ntawm ignition coil

Thaum ignition coils tau tsim kom kav ntev, qhov xav tau ntau ntxiv rau lawv txhais tau tias lawv tuaj yeem ua tsis tiav. Ntawm cov laj thawj tseem ceeb rau lawv txoj kev tawg yog cov hauv qab no.

Cov kab hluav taws xob puas lossis lawv cov xov hlau puas. Lub faulty spark plug nrog siab kuj ua rau cov zis voltage nce. Yog tias nws siab tshaj 35 volts, lub coil rwb thaiv tsev tawg yuav tshwm sim, uas yuav ua rau luv luv Circuit Court. Qhov no tuaj yeem ua rau txo qis hauv qhov tso zis hluav taws xob, tsis ua haujlwm nyob rau hauv kev thauj khoom thiab / lossis tsis zoo pib ntawm lub tshuab hluav taws xob sab hauv.

Hnav spark plug los yog nce qhov sib txawv. Raws li lub txim hluav taws xob hnav, qhov sib txawv ntawm ob lub electrodes teem rau nws kuj yuav nce ntxiv. Qhov no txhais tau hais tias lub kauj yuav tsum tsim kom muaj hluav taws xob ntau dua los tsim lub txim. Ib qho ntxiv load ntawm lub kauj tuaj yeem ua rau overload thiab overheating.

kev vibration defect. Kev hnav tsis tu ncua vim kev vibration ntawm lub cav combustion sab hauv tuaj yeem ua rau muaj qhov tsis xws luag hauv cov windings thiab rwb thaiv tsev ntawm cov hluav taws xob hluav taws xob, uas ua rau lub voj voog luv luv lossis qhib Circuit Court nyob rau hauv qhov thib ob winding. Nws tseem tuaj yeem xoob qhov hluav taws xob txuas txuas nrog lub txim hluav taws xob, ua rau lub tshuab hluav taws xob hluav taws xob ua haujlwm ntxiv los tsim lub txim taws.

Overheating. Vim lawv qhov chaw nyob, cov coils feem ntau raug rau qhov kub thiab txias uas tshwm sim thaum lub sijhawm ua haujlwm ntawm lub cav combustion sab hauv. Qhov no tuaj yeem txo qhov peev xwm ntawm cov coils los ua tam sim no, uas nyob rau hauv lem yuav txo lawv cov kev ua tau zoo thiab kav ntev.

Hloov tsis kam. Ib qho luv luv los yog tsis tshua muaj zog nyob rau hauv winding ntawm lub kauj yuav ua rau kom tus nqi ntawm cov hluav taws xob ntws los ntawm nws. Qhov no tuaj yeem ua rau tag nrho lub tshuab hluav taws xob ntawm lub tsheb puas. Ib qho kev hloov hauv kev tiv thaiv kuj tuaj yeem ua rau lub txim tsis muaj zog, uas ua rau lub tsheb tsis tuaj yeem pib thiab ua rau ob qho tib si coil thiab cov khoom nyob ze.

Ua kua ingress. Feem ntau, lub hauv paus ntawm cov kua yog roj los ntawm lub puas valve cover gasket. Cov roj no sib sau ua ke thiab ua rau ob qho tib si coil thiab lub txim hluav taws xob. Cov dej los ntawm lub tshuab cua txias, piv txwv li, tuaj yeem nkag mus rau hauv qhov hluav taws xob. Nyob rau hauv ob qho tib si, txhawm rau kom tsis txhob rov ua dua qhov zoo sib xws, nws yog ib qho tseem ceeb kom tshem tawm cov hauv paus ntsiab lus ntawm kev tawg.

Yuav ua li cas to taub hais tias lub ignition coil yog tuag?

Cov kev puas tsuaj uas tau teev tseg hauv qab no tuaj yeem tshwm sim los ntawm lwm yam laj thawj, yog li kev kuaj mob tseem yuav tsum tau ua kom tiav, suav nrog los ntawm kev tshuaj xyuas qhov xwm txheej ntawm cov hluav taws xob hluav taws xob.

Yog li, cov tsos mob ntawm kev puas tsuaj tuaj yeem muab faib ua ob hom - kev coj cwj pwm thiab kev pom. Kev coj cwj pwm muaj xws li:

• Lub teeb kos lub cav yog nyob rau.
• Kev siv roj ntau ntxiv.
• Tua nyob rau hauv lub tso pa system. Nws tshwm sim thaum cov roj uas tsis tau hlawv nyob rau hauv lub combustion chamber nkag mus rau hauv lub pa system.
• ICE nres. Lub faulty ignition kauj yuav muab tam sim no rau lub txim plugs intermittently, uas yuav ua rau lub cav nres.
• Kev tsis ncaj ncees. Tsis muaj lub zog los ntawm ib lossis ntau lub tog raj kheej tuaj yeem ua rau lub cav tsis zoo, tshwj xeeb tshaj yog thaum lub sijhawm nrawm.
• Teeb meem nrog pib lub cav. Yog hais tias ib qho los yog ib lub teeb tswm ciab tsis tau txais cov nqi txaus, lub tshuab hluav taws xob sab hauv yuav nyuaj heev los pib. Lub tsheb nrog ib lub kauj yuav tsis pib txhua qhov hauv qhov no.
• Internal combustion engine pib mus rau "troit". Thiab thaum lub sij hawm, qhov teeb meem no zuj zus, uas yog, "trimming" yog qhia ntau thiab ntau kom meej meej, lub zog thiab dynamics ntawm lub internal combustion engine yog ploj. "Tripling" feem ntau tshwm sim nyob rau hauv nag (ntub) huab cua thiab thaum pib lub combustion engine "kom txias".
• Thaum sim ua kom nrawm nrawm, "kev ua tsis tiav" tshwm sim, thiab thaum idling, lub cav ceev tsis nce nrawm rau tib txoj kev. Kuj tseem muaj hluav taws xob poob hauv kev thauj khoom.
• Qee qhov xwm txheej (ntawm cov tsheb laus) qhov tsis hnov ​​​​tsw ntawm cov roj av uas tsis muaj hluav taws xob tuaj yeem muaj nyob hauv chav tsev. Ntawm cov tsheb tshiab, qhov xwm txheej zoo sib xws tuaj yeem tshwm sim thaum, tsis yog ntau dua lossis tsawg dua cov pa huv huv, cov ntxhiab tsw ntawm cov roj av uas tsis tau hlawv ntxiv rau lawv.

Ntxiv rau tag nrho cov saum toj no, cov cim qhia ntawm coil tsis ua haujlwm tuaj yeem pom thiab thaum kuaj pom:

• Lub xub ntiag ntawm "kev sib tawg lem" ntawm lub coil lub cev. Ntawd yog, cov yam ntxwv tsaus nti kab txaij raws li hluav taws xob "flashes". Hauv qee qhov, tshwj xeeb tshaj yog "tsis quav ntsej", cov nplai tshwm sim ntawm cov lem.
• Hloov (turbidity, blackening) ntawm cov xim ntawm dielectric ntawm lub ignition coil vaj tse.
• Darkening ntawm hluav taws xob tiv tauj thiab connectors vim lawv hlawv.
• Cov cim ntawm overheating ntawm lub coil lub cev. Feem ntau lawv tau hais tawm hauv qee qhov "streaks" lossis kev hloov pauv hauv cov duab geometry ntawm rooj plaub hauv qee qhov chaw. Nyob rau hauv cov xwm txheej "hnyav", lawv yuav muaj ntxhiab tsw.
• High contamination ntawm lub coil lub cev. Tshwj xeeb tshaj yog nyob ze hluav taws xob tiv tauj. Qhov tseeb yog tias hluav taws xob tawg tuaj yeem tshwm sim meej ntawm cov plua plav lossis av. Yog li ntawd, lub xeev no yuav tsum tsis txhob raug tso cai tshwm sim.

Lub ntsiab cim ntawm lub kauj tsis ua haujlwm yog qhov tsis muaj qhov sib xyaw ntawm cov roj sib tov. Txawm li cas los xij, qhov xwm txheej no tsis yog ib txwm tshwm sim, txij li qee qhov xwm txheej ntawm lub zog hluav taws xob tseem mus rau tswm ciab, thiab tsis yog rau lub cev xwb. Hauv qhov no, koj yuav tsum tau kuaj xyuas ntxiv.

Cov cim qhia ntawm kev puas tsuaj tau piav qhia saum toj no muaj feem cuam tshuam yog tias ib tus neeg ignition coils tau nruab rau hauv lub cav. Yog hais tias tus tsim muab rau lub installation ntawm ib tug coil rau tag nrho cov cylinders, ces lub internal combustion engine yuav nres kiag li (qhov no, qhov tseeb, yog ib tug ntawm cov laj thawj vim li cas ib tug txheej ntawm ib tug modules yog ntsia rau niaj hnub machinery).
