4-Wire Ignition Coil Schematic (Ua tiav Daim Ntawv Qhia)
Txheem
Kab lus no yuav muab cov ntaub ntawv tsim nyog txog 4-xaim ignition coil circuit.
Lub tshuab hluav taws xob hluav taws xob yog lub plawv ntawm lub tshuab hluav taws xob, thiab cov hluav taws xob hluav taws xob tsis zoo tuaj yeem ua rau hluav taws xob hluav taws xob tsis zoo, ua rau lub tog raj kheej tsis zoo. Yog li koj yuav tsum muaj peev xwm txheeb xyuas 4 tus pins kom raug thaum siv 4 hlau ignition kauj. Hauv tsab xov xwm luv luv no, kuv yuav qhia koj txhua yam kuv paub txog lub voj voog ntawm plaub-xaim ignition coil thiab nws ua haujlwm li cas.
Lub tshuab hluav taws xob hluav taws xob tuaj yeem tsim hluav taws xob ntau heev (txog 50000V) siv lub roj teeb hluav taws xob 12V. Lub 4-xaim ignition coil muaj plaub tus pins; 12V IGF, 5V IGT thiab hauv av.
Kuv yuav hais ntxiv txog cov txheej txheem hluav taws xob hluav taws xob no hauv kab lus hauv qab no.
Lub ignition coil ua dab tsi?
Cov hluav taws xob hluav taws xob hloov hluav taws xob tsawg ntawm 12V mus rau qhov hluav taws xob ntau dua. Nyob ntawm qhov zoo ntawm ob lub windings, qhov voltage no tuaj yeem ncav cuag 50000V. Qhov hluav taws xob no yog siv los tsim lub txim uas xav tau rau cov txheej txheem combustion nyob rau hauv lub cav (nrog rau lub txim taws). Yog li koj tuaj yeem xa mus rau qhov hluav taws xob hluav taws xob ua ib qho luv luv-up transformer.
Ceev Ntsis: Qee cov kws kho tsheb siv lo lus "tshwj xeeb" los xa mus rau lub tshuab hluav taws xob.
Daim duab ntawm 4-xaim ignition kauj
Thaum nws los txog rau ignition coils, lawv tuaj nyob rau hauv ntau variations. Piv txwv li, koj tuaj yeem pom 2-xaim, 3-xaim lossis 4-xaim ignition coils hauv cov qauv tsheb sib txawv. Hauv tsab xov xwm no, kuv yuav tham txog 4-xaim ignition kauj. Yog li vim li cas 4-xaim ignition coil yog li tshwj xeeb? Cia peb kawm paub.
Ua ntej, 4-xaim ignition coil muaj plaub tus pins. Kawm cov duab saum toj no rau daim duab kab hluav taws xob ntawm lub coil pob.
- hu rau 12 V
- Pin 5V IGT (reference voltage)
- pin IGF
- Kev sib cuag hauv av
12V tiv tauj los ntawm qhov hluav taws xob hloov hluav taws xob. Lub roj teeb xa ib lub teeb liab 12V mus rau lub ignition coil los ntawm lub ignition switch.
5V IGT tus pin ua raws li kev siv hluav taws xob rau 4-xaim ignition kauj. Tus pin no txuas mus rau ECU thiab ECU xa lub teeb liab 5V rau lub ignition kauj los ntawm tus pin no. Thaum lub ignition coil tau txais qhov teeb meem no, nws tua lub kauj.
Ceev Ntsis: Qhov no 5V siv hluav taws xob muaj txiaj ntsig zoo rau kev ntsuas hluav taws xob coils.
Cov zis IGF xa cov teeb liab mus rau ECU. Cov teeb liab no yog ib qho kev pom zoo ntawm kev noj qab haus huv ntawm lub ignition coil. ECU txuas ntxiv ua haujlwm tsuas yog tom qab tau txais cov teeb liab no. Thaum ECU tsis pom IGF teeb liab, nws xa code 14 thiab nres lub cav.
Tus pin hauv av txuas rau txhua qhov chaw hauv av hauv koj lub tsheb.
Yuav ua li cas 4-xaim ignition coil ua haujlwm
4-xaim ignition kauj muaj peb lub ntsiab; hlau core, thawj winding thiab theem nrab winding.
Thawj winding
Thawj winding yog ua los ntawm tuab tooj liab hlau nrog 200 mus rau 300 lem.
Secondary winding
Qhov thib ob winding kuj yog ua los ntawm cov tooj liab tuab, txog 21000 lem.
hlau core
Nws yog ua los ntawm ib tug laminated hlau core thiab muaj peev xwm khaws cia lub zog nyob rau hauv daim ntawv ntawm ib tug magnetic teb.
Thiab qhov no yog li cas peb qhov no tsim txog 50000 volts.
- Thaum tam sim no dhau los ntawm cov thawj, nws tsim ib qho chaw sib nqus nyob ib ncig ntawm cov tub ntxhais hlau.
- Vim tias cov txheej txheem tau piav qhia saum toj no, qhov kev sib txuas tiv thaiv kev sib txuas raug txiav. Thiab rhuav tshem cov hlau nplaum ib yam nkaus.
- Qhov kev txiav tam sim no tsim muaj qhov hluav taws xob siab heev (kwv yees li 50000 V) nyob rau hauv qhov thib ob winding.
- Thaum kawg, qhov hluav taws xob siab no tau xa mus rau lub txim hluav taws xob los ntawm qhov hluav taws xob distributor.
Koj yuav ua li cas thiaj paub yog tias koj lub tsheb muaj qhov hluav taws xob tsis zoo?
Lub ignition coil tsis zoo yuav ua rau txhua yam teeb meem rau koj lub tsheb. Piv txwv li, lub cav yuav pib nres thaum lub tsheb nrawm. Thiab lub tsheb tuaj yeem nres vim qhov teeb meem no.
Ceev Ntsis: Misfires tuaj yeem tshwm sim thaum ib lossis ntau lub tog raj kheej ignite tsis raug. Qee zaum lub tog raj kheej yuav tsis ua haujlwm tag nrho. Tej zaum koj yuav tau sim lub ignition coil module thaum qhov no tshwm sim.
Ntxiv nrog rau lub cav misfires, muaj ob peb lwm yam cim ntawm ib tug phem ignition kauj.
- Xyuas seb lub cav lub teeb yog nyob rau
- Sudden poob hwj chim
- Kev lag luam roj tsis zoo
- Nyuaj pib lub tsheb
- Suab nrov thiab hnoos
Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.
- Yuav ua li cas txuas ignition coil circuit
- Yuav ua li cas kuaj lub kauj tiv pa taws nrog multimeter
- Yuav ua li cas los xyuas lub ignition control unit nrog ib tug multimeter
