Kodi cholumikizira cha spark cha galimoto n'chiyani?
Cholumikizira cha spark cha galimoto ndi gawo lofunika kwambiri mu makina oyatsira moto a injini ya petulo. Ntchito yake ndikulowetsa mphamvu yamagetsi m'chipinda choyatsira moto, kutulutsa mphamvu kudzera mu electrode gap kuti apange mphamvu yamagetsi, kuyatsa chisakanizo choyaka mu silinda, ndikuyendetsa injini kuti igwire ntchito.
Ntchito yaikulu ndi kapangidwe ka pulagi ya spark
Youdaoplaceholder0 Ntchito yayikulu .
Mphamvu yamagetsi yopangidwa ndi coil yoyatsira moto (nthawi zambiri imapitirira ma volts 10,000) imalowetsedwa mu chipinda choyatsira moto. Kudzera mu electrode gap discharge, spark imapangidwa kuti iyatse chisakanizo choyaka mu silinda ndikuyendetsa injini kuti igwire ntchito.
Kagwiridwe ka ntchito ka injini kamakhudza mwachindunji mphamvu zake komanso kugwiritsa ntchito mafuta moyenera, ndipo ndi gawo lofunikira kwambiri pakugwira ntchito kwabwinobwino kwa injini.
Youdaoplaceholder0 gawo .
Youdaoplaceholder0 Electrode yapakati : Yolumikizidwa ku magetsi amphamvu kwambiri, yomwe imayang'anira kutulutsa mphamvu kuti ipange ma sparks.
Youdaoplaceholder0 Electrode yokhazikika : Imapanga mpata wotulutsira madzi ndi electrode yapakati (nthawi zambiri 0.6-1.2 mm).
Choteteza cha Youdaoplaceholder0 : chimachotsa electrode yapakati kuchokera ku electrode yokhazikika kuti chiteteze ma circuits afupiafupi.
Nyumba yachitsulo ya Youdaoplaceholder0 : yokhala ndi ulusi, wogwiritsidwa ntchito pomangirira ku silinda ya injini.
Mfundo yogwirira ntchito ya Youdaoplaceholder0
Youdaoplaceholder0 njira yoyatsira moto ya magawo anayi :
Choyatsira moto chimapanga magetsi ambiri kumapeto onse a electrode ya spark plug, yomwe imaphwanya mpweya ndikupanga arc.
Mzerewu umatenthetsa mpweya wosakanikirana pa kutentha kwakukulu, ndikupanga pakati pa moto.
Lawilo limafalikira ndi kuyaka, zomwe zimapangitsa kuti pisitoni isunthe.
Mphamvu zomwe zimapangidwa ndi kuyaka zimasanduka mphamvu yamakina kuti ziyendetse galimoto kuti iyende.
Mtundu ndi kusankha kwa Youdaoplaceholder0
Mtundu wa Youdaoplaceholder0 wa calorific : Umagawidwa m'mitundu yozizira, mitundu yotentha ndi mitundu yapakatikati. Kusankhaku kumadalira chiŵerengero cha kupsinjika kwa injini ndi mikhalidwe yogwirira ntchito (mwachitsanzo, mtundu wozizira umagwiritsidwa ntchito pa injini zothamanga kwambiri ndi mtundu wotentha pa injini zothamanga pang'ono).
Zipangizo za ma electrode a Youdaoplaceholder0 : Zipangizo zodziwika bwino zimaphatikizapo ma aloyi a nickel, ma aloyi asiliva, ma aloyi a platinamu, ndi zina zotero, zomwe zimakhudza nthawi ya moyo wa ma spark plugs ndi kukhazikika kwa kuyaka.
Ntchito yaikulu ya pulagi ya spark ya galimoto ndikuyatsa mpweya wosakanikirana mu silinda ya injini popanga spark yamagetsi, motero kuyendetsa galimotoyo kuti iziyenda. Ntchito zake ndi izi:
Ntchito yoyatsira
Pulagi ya spark imayambitsa magetsi ambiri mu chipinda choyaka moto, imatuluka kudzera mu electrode gap kuti ipange spark yamagetsi, ndikuyatsa chisakanizo choyaka mu silinda. Iyi ndi sitepe yofunika kwambiri pakugwira ntchito kwa injini.
Yang'anirani njira yoyaka moto
Mwa kusintha nthawi ndi mphamvu zoyatsira moto, kukonza liwiro la kuyaka, kutentha ndi kupanikizika, injini imagwira ntchito bwino, komanso kuchepetsa mpweya woipa.
Kuwongolera kugwiritsa ntchito bwino mafuta
Kukonza bwino njira yoyatsira moto kungawonjezere kugwiritsa ntchito mafuta, kuchepetsa kugwiritsa ntchito mafuta, komanso kuchepetsa kutulutsa kwa nthunzi ya mafuta osayaka ndi zinthu zoipitsa.
Kuyeretsa zotsatira
Kutulutsa kwa ma electrode mu spark plug kumapanga chinthu chotchedwa ionization, chomwe chimathandiza kuchotsa dothi ndi matope mkati mwa injini ndikusungabe yoyera.
Mapulagi a spark a zinthu zosiyanasiyana (monga ruthenium gold) amatha kuchepetsa mpweya woipa ndikuwonjezera nthawi yosinthira, koma njira yosamalira galimotoyo iyenera kusinthidwa malinga ndi malo omwe galimotoyo imagwiritsira ntchito komanso momwe imayendetsera galimotoyo.
Zizindikiro zazikulu za vuto la pulagi yamoto ndi kuyatsa kosazolowereka, kuchepa kwa mphamvu komanso kuchuluka kwa mafuta omwe amagwiritsidwa ntchito, ndi zina zotero. Ziyenera kukonzedwa kapena kusinthidwa nthawi yomweyo kudzera mu kuzindikira bwino.
Chizindikiro chachikulu cha kulephera kwa plug ya spark ndi
Youdaoplaceholder0 Kuyambitsa ndi kuyatsa zinthu zachilendo .
Kuyamba kozizira kumafuna kuyesera kangapo ndipo kungalepheretse kuyaka konse.
Injini ikayamba kuyaka, imagwedezeka kwambiri, ndipo liwiro lake limasintha ndi ma revolutions opitilira 200 pamphindi.
Youdaoplaceholder0 Kuchepa kwa mphamvu yamagetsi .
Kuyankha kwachangu kumakhala kochedwa, ndipo mphamvu yotulutsa imachepetsedwa ndi 15% mpaka 20% mukadutsa kapena kukwera mapiri.
Nthawi yofulumira ya 0-100km/h ikhoza kukulitsidwa ndi masekondi 1.5 mpaka 2.3.
Youdaoplaceholder0 Kugwiritsa ntchito mphamvu molakwika komanso kutulutsa mpweya woipa.
Kugwiritsa ntchito mafuta kumawonjezeka ndi 10% mpaka 15%, ndipo utsi wakuda kapena wabuluu umawonekera mu utsi wotulutsa utsi.
Kutuluka kwa ma hydrocarbon kumatha kupitirira muyezo katatu, zomwe zimakhudza kuchuluka kwa kupitilira kwa kuwunika kwapachaka.
Kusanthula chifukwa cha vuto
Youdaoplaceholder0 kutayika kwa ma electrode ndi kuyika kwa kaboni .
Pambuyo poti pulagi yodziwika bwino yagwiritsidwa ntchito kwa makilomita opitilira 30,000, kuwonongeka kwa ma electrode kumatha kufika 0.3mm, ndipo kusiyana kwakukulu kumapangitsa kuti magetsi oyatsira akwere.
Kuchuluka kwa mpweya wosakanikirana kapena zinyalala zambiri mu mafuta kungayambitse carbonization ya elekitirodi.
Youdaoplaceholder0 Kukhazikitsa ndi zinthu zachilengedwe .
Kulephera kuyiyika motsatira mphamvu yamagetsi kungayambitse kutaya kutentha bwino komanso kusungunula ma electrode.
Mikhalidwe yogwirira ntchito yotenthetsera kwambiri komanso yopanikizika kwambiri nthawi yayitali imachedwetsa kukalamba kwa ma spark plugs.
Cholakwika cha ubale wa dongosolo la Youdaoplaceholder0 .
Kulephera kwa coil yoyatsira moto, kutsekeka kwa fyuluta ya mpweya ndi zinthu zina zimayambitsa ma spark plugs osazolowereka.
Youdaoplaceholder0 Njira yosamalira ndi kukonza
Njira zodziwira matenda za Youdaoplaceholder0 .
Yang'anani mtundu wa electrode ya spark plug: Nthawi zambiri imakhala yofiirira. Yakuda imasonyeza kuti chisakanizocho ndi cholemera kwambiri, ndipo choyera chingakhale chizindikiro cha kutuluka kwa madzi ozizira.
Kuyesa kwa spark yamagetsi amphamvu: Ngati palibe spark pamalo olumikizira spark plug, iyenera kusinthidwa.
Youdaoplaceholder0 njira zoyendetsera .
Ma carbon dioxide ofooka amatha kutsukidwa mwaukadaulo. Ma electrode ogwiritsidwa ntchito kuposa 0.8mm kapena okhala ndi mpata woposa 1.2mm ayenera kusinthidwa.
Mukasintha, seti yonse iyenera kusinthidwa kuti ipewe kugwedezeka komwe kumachitika chifukwa cha kusiyana kwa magwiridwe antchito pakati pa ma electrode atsopano ndi akale.
Youdaoplaceholder0 Kusamalira koteteza .
Mainjini okhala ndi turbocharger amalimbikitsidwa kuti aziwunikidwa makilomita 30,000 aliwonse, ndipo mainjini okhala ndi mpweya wachilengedwe osapitirira makilomita 50,000.
Sankhani mapulagi a iridium/platinamu (okhala ndi moyo wa makilomita 80,000 mpaka 100,000) ndipo pewani kugwiritsa ntchito zinthu zosafunika kwenikweni.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa MG&MAXUSzida zamagalimoto zalandiridwa kugula.
