Choyikira cha kuyatsa: Chimake chachikulu cha mphamvu ya injini
Choyatsira moto ndiye gawo lalikulu la makina oyatsira moto a galimoto. Kwenikweni, ndi chosinthira chapadera cha pulse. Ntchito yake yayikulu ndikusintha magetsi otsika a 12V omwe amaperekedwa ndi batri kukhala magetsi amphamvu a 15,000-30,000V, zomwe zimapangitsa kuti choyatsira moto chipange mphamvu yamagetsi, motero kuyatsa chisakanizocho mu silinda ya injini ndikuyendetsa injini kuti igwire ntchito.
Imagwira ntchito potengera mfundo ya induction ya maginito: Pamene coil yoyamba iperekedwa ndi mphamvu yamagetsi yochepa, mphamvu yamagetsi imapangidwa ndipo mphamvu imasonkhanitsidwa. Wowongolera kuyatsa akadula mphamvu yamagetsi, mphamvu yamagetsi yomwe imasintha mofulumira imayambitsa magetsi amphamvu kwambiri mu kuzunguliza kwachiwiri komwe kumazungulira kwambiri kuposa kuzunguliza koyamba. Mphamvu yamagetsi amphamvu imeneyi imadutsa mu pulagi ya spark kuti ipange mpweya kukhala wamagetsi ndikupanga mphamvu yamagetsi, ndikuyatsa nthawi yomweyo. Njirayi iyenera kufananizidwa bwino ndi momwe injini imagwirira ntchito. ECU idzasintha nthawi yoyatsira magetsi nthawi yeniyeni kutengera magawo monga liwiro ndi katundu kuti zitsimikizire kuti mphamvu zikuyenda bwino komanso moyenera.
Kuwonjezera pa kusintha kwa mphamvu yamagetsi, choyatsira moto chimakhudza mwachindunji magwiridwe antchito a injini: Kuyatsa bwino kumatha kupititsa patsogolo kuyaka bwino, kuchepetsa kugwiritsa ntchito mafuta ndi kutulutsa utsi; kapangidwe kodziyimira pawokha koyatsira moto (choyatsira chimodzi pa silinda imodzi) kumatha kuchepetsa kutayika kwa mphamvu ndikuwonjezera kukhazikika kwa mphamvu pakugwira ntchito mwachangu; ma choyatsira ena omwe ali ndi ntchito zozindikira kuyaka amathanso kupereka ndemanga pa momwe kuyaka kulili, ndikuwonjezera kulamulira kuyaka.
Chenjezo la cholakwika: Zizindikiro zisanu ndi chimodzi zomwe muyenera kuzisamala nazo
Choyatsira moto chimagwira ntchito pamalo otentha kwambiri, opanikizika kwambiri, komanso ogwedezeka pafupipafupi, zomwe zimapangitsa kuti chikhale chovuta kukalamba komanso ma coil short circuits. Zizindikiro zotsatirazi nthawi zambiri zimawonedwa:
Kugwedezeka kwakukulu kwa mpweya woipa: Kulephera kwa coil yoyatsira ya silinda imodzi kungayambitse kusowa kwa mafuta, zomwe zimapangitsa kuti injini isagwire bwino ntchito. Thupi la galimoto ndi chiwongolero zidzagwedezeka kwambiri zikangoyima, ndipo chitoliro chotulutsa utsi chidzatulutsa phokoso "lophulika". Kukhudza chitoliro chotulutsa utsi kudzawonetsa kugwedezeka kosazolowereka.
Kuthamanga kofooka chifukwa cha kuyima: Mphamvu yoyatsira yosakwanira imayambitsa kuyaka kosakwanira kwa chisakanizocho, zomwe zimapangitsa kuti liwiro lichedwe. Kuyima kwakanthawi kumachitika pamlingo wa 2000-3000 rpm, ndipo kutayika kwa mphamvu kumakhala kofunika kwambiri pakukwera.
Kugwiritsa ntchito mafuta mopitirira muyeso: Kusakaniza kosayaka kumatulutsidwa mwachindunji, zomwe zimapangitsa kuti kugwiritsa ntchito mafuta kuwonjezereke ndi 10%-30%. Nthawi yomweyo, utsi umatulutsa fungo la mafuta onunkhira, ndipo khoma lamkati la chitoliro chotulutsa utsi lingakhale ndi madontho a mafuta.
Kuwala kwa cholakwika kumawunikira ndi ma code enieni a cholakwika: ECU ikazindikira vuto la kuyatsa, imawunikira kuwala kwa cholakwika cha injini. Chida chodziwira nthawi zambiri chimawerenga ma code olakwika monga P0300 (kuphulika mwachisawawa) kapena P0301-P0304 (kuphulika mwachisawawa kwa silinda yeniyeni).
Kuvuta kuyamba: Mu nyengo yozizira, mphamvu ya insulation ya coil yoyatsira moto imachepa, sizingathe kupereka magetsi okwanira amphamvu, zomwe zimapangitsa kuti injini izitha kuyatsa mobwerezabwereza panthawi yozizira, ndipo milandu yoopsa ingayambitse kuti injini izime nthawi yomweyo ikayamba kugwira ntchito.
Kusawoneka bwino ndi magwiridwe antchito: Ming'alu kapena zizindikiro za moto zimaonekera pamwamba pa coil, kapena pulagi yolumikizira imadetsedwa ndi mafuta ndipo yadzimbirika. Izi zikusonyeza kuti gawo loteteza kutentha lawonongeka; ngati mtengo wotsutsa uli pamwamba pa mulingo woyenera (kukana kwachiwiri nthawi zambiri kumakhala 5000-70000Ω), ndikofunikira kuisintha mwachangu.
Kukonza ndi kusintha: Kukulitsa moyo wautumiki mwasayansi
Kusinthasintha kwa choyikira choyatsira moto si mtengo wokhazikika. Kawirikawiri, makilomita 100,000 amalimbikitsidwa ngati malo ofotokozera, koma kuyenera kusinthidwa kutengera momwe zinthu zilili: Kwa magalimoto ogwira ntchito bwino, omwe amayendetsedwa m'malo otentha kwambiri komanso chinyezi kwa nthawi yayitali, kapena omwe amayendetsedwa mobwerezabwereza mtunda waufupi, kusintha kuyenera kuchepetsedwa; ngati kukonza koyenera tsiku ndi tsiku kukuchitika, ma coil ena angagwiritsidwe ntchito kwa makilomita opitilira 150,000.
Kusamalira tsiku ndi tsiku kuyenera kudziwika: Pewani kuimitsa injini kwa nthawi yayitali kuti coil isatenthe kwambiri; yang'anani nthawi zonse spark plug gap (kaya yayikulu kwambiri kapena yaying'ono kwambiri idzapangitsa kuti coil ikule msanga); gwiritsani ntchito mafuta abwino kwambiri kuti muchepetse mpweya woipa; pewani kusiya choyatsira moto chikugwira ntchito kwa nthawi yayitali injini ikasiya kugwira ntchito. Ngati vuto lachitika, ndikofunikira kuisintha mwachangu. Coils zosagwira ntchito bwino zimatha kuwonongeka msanga chifukwa cha zinthu zosagwira ntchito bwino komanso njira zosakhazikika zozungulira coil. Ndikofunikira kusankha zida zoyambirira za fakitale kapena zodziwika bwino.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
