Momwe mungayang'anire koyilo yoyatsira

Koyilo yoyatsira imapangidwa kuti ipange mphamvu yayikulu, yomwe imagwiritsidwa ntchito ndi spark plug kuti ipange spark. Choncho, ntchito yake yoyenera ndi yofunikira kuti ntchito yoyatsira igwire bwino. M'malo mwake, koyiloyo ndi thiransifoma yaying'ono, yoyambira yoyambira yomwe imalandira muyezo wa 12 V kuchokera ku batri, ndipo mphamvu ya kV zingapo imatuluka. Amagwiritsidwa ntchito pamakina onse oyatsira - kukhudzana, osalumikizana ndi zamagetsi. Zifukwa za kulephera kwa koyilo ndizofanana. kawirikawiri, izi ndi waya yopuma, kutchinjiriza kuwonongeka, mapindikidwe makina. ndiye tiwona zizindikiro za kuwonongeka ndi njira zodziwira coil yoyatsira.

Mfundo ya ntchito ya coil poyatsira

Monga tafotokozera pamwambapa, koyilo yoyatsira ndi chosinthira chamagetsi chokwera chomwe chimasintha voliyumu yolandila 12V kukhala voteji yokhala ndi ma kilovolts angapo. Mwadongosolo, koyiloyo imakhala ndi ma windings awiri - pulayimale ndi yachiwiri (motsatana, otsika komanso okwera). Komabe, kutengera mtundu wa koyilo, ma windings ndi malo awo amasiyana.

Tiyeni tiyambe ndi zosavuta koyilo wamba. Pano, pali 100 ... 150 kutembenukira pa mapiringidzo oyambirira. Mapiritsiwo amavulazidwa ndi waya wamkuwa wotsekedwa. Mapeto ake amabweretsedwa ku thupi la koyilo. Chiwerengero cha kutembenuka kwa mafunde apamwamba kwambiri ndi 30 ... 50 zikwi (malingana ndi chitsanzo). Mwachilengedwe, waya wogwiritsidwa ntchito pano ndi wocheperako kwambiri. "Minus" ya mapiritsi achiwiri amalumikizidwa ndi "minus" ya pulayimale. Ndipo "kuphatikiza" kumalumikizidwa ndi terminal pachivundikiro. izi zimatsimikizira kuti mphamvu yamagetsi yomwe imabwera chifukwa chapamwamba imatayika.

kuti awonjezere mphamvu ya maginito, ma windings amazungulira pakatikati pazitsulo. Nthawi zina, pofuna kupewa kutenthedwa, ma windings ndi pachimake amadzazidwa ndi mafuta a transformer (sikungozizira dongosolo, komanso insulator).

Tsopano tiyeni tione munthu poyatsira koyilo. Palinso ma windings awiri apa, koma kusiyana kuli komwe kuli. ndiko kuti, amalangidwa mokhotakhota. Kumangirira koyambirira kumakhala ndi phata lamkati, ndipo chachiwiri chimakhala ndi phata lakunja.

Ma coil oyatsira pawokha amayikidwa m'makina omwe ali ndi magetsi. Choncho, mapangidwe awo ndi ovuta. Chifukwa chake, kuti muchepetse mphamvu yayikulu pakumangirira kwachiwiri, diode imaperekedwa. komanso mbali ya koyilo payekha ndi chakuti chifukwa mkulu voteji sapita kwa distribuerar (monga akachitidwe akale), koma spark plugs. Izi zidatheka chifukwa cha kapangidwe kake, komwe kumaphatikizapo nyumba yotsekeredwa, ndodo ndi kasupe.

komanso mtundu umodzi wa koyilo - pini ziwiri. Amapereka magetsi ku masilindala awiri nthawi imodzi. Pali mitundu ingapo ya izo. nthawi zambiri, makoyilo oterowo amaphatikizidwa kukhala gawo limodzi wamba, lomwe kwenikweni ndi coil ya pini inayi yoyatsira.

Mosasamala mtundu wa koyilo yoyatsira, gawo lawo lalikulu laukadaulo, lomwe muyenera kuyang'ana mukamazindikira, ndiko kukana kwa ma windings. ndicho, kukana kwa mapiringidzo oyambirira nthawi zambiri kumakhala mu 0,5 ... 3,5 ohms, ndi yachiwiri - 6 ... ). Miyeso imapangidwa pogwiritsa ntchito zida zachikhalidwe - ma multimeter kapena ohmmeters. Ngati mtengo wopezedwa ndi wosiyana kwambiri ndi mtengo womwe watchulidwa, ndiye kuti n'kutheka kuti coil ili kunja kwa dongosolo.

muyeneranso kudziwa kuti koyilo iliyonse ili ndi zizindikiro zosiyanasiyana:

• kukana kwa mafunde;
• nthawi ya spark;
• spark mphamvu;
• spark current;
• kukhazikitsidwa kwa chigawo choyamba.

Chifukwa chake, kuti mumvetsetse momwe kuwerengera kwa koyilo kumayenderana ndi zomwe zimachitika, muyenera kufotokozera zaukadaulo wa koyilo yanu. Izi ndizothandiza makamaka kwa inu ngati spark yasowa, popeza coil poyatsira ndi chimodzi mwazinthu zoyamba zadongosolo kuti ziwunikidwe.

Zizindikiro za kusokonekera

Pali zizindikiro zingapo za coil yoyaka moto yomwe yalephera. Mwa iwo:

• injini imayamba "kuthamanga", ndipo vutoli limakula pakapita nthawi;
• mu kuzizira, galimoto "troit" mpaka kutenthetsa;
• kusokoneza ntchito ya injini yoyaka mkati mu nyengo yamvula;
• Mukakanikiza chowongolera chowongolera mwamphamvu, kulephera kwagalimoto kumawonedwa.

Ngati koyiloyo ili ndi vuto pamakina omwe ali ndi ECU, chizindikiro cha Check Engine pa dashboard chimatsegulidwa. Komabe, zizindikiro zomwe zatchulidwazi zitha kuwonetsanso zovuta zina, zomwe ndi ma spark plugs. Koma pamene chimodzi mwa izo chikuwonekera, m'pofunika kuzindikira coil (s). Mukalumikiza scanner yowunikira, imatha kuwonetsa zolakwika P0363.

Zomwe zimayambitsa zovuta

Pali zifukwa zingapo zomwe koyilo yoyatsira imalephera kwathunthu kapena pang'ono. Mwa iwo:
