Pulagi yoyatsira moto.
Pulagi ya Spark, yomwe imadziwika kuti nozzle ya moto, ntchito yake ndikutulutsa magetsi amphamvu kwambiri omwe amatumizidwa ndi waya wamagetsi amphamvu kwambiri (mzere wa nozzle ya moto), kuswa mpweya pakati pa ma electrode awiri a spark plug, ndikupanga ma spark amagetsi kuti ayatse mpweya wosakanikirana mu silinda. Mitundu yayikulu ndi iyi: pulagi ya spark yamtundu wa quasi, pulagi ya spark yotuluka m'mphepete mwa thupi, pulagi ya spark yamtundu wa electrode, pulagi ya spark yamtundu wa mpando, pulagi ya spark yamtundu wa pole, pulagi ya spark yamtundu wa surface jump ndi zina zotero.
Pulagi yoyatsira moto imayikidwa m'mbali kapena pamwamba pa injini. Pulagi yoyatsira moto yoyambirira imalumikizidwa ndi chogawa ndi chingwe cha silinda. M'zaka khumi zapitazi, injini ya galimotoyo yasintha kwambiri choyatsira moto ndipo choyatsira moto chimalumikizidwa mwachindunji. Mphamvu yogwira ntchito ya choyatsira moto ndi osachepera 10000V, ndipo mphamvu yokwera imapangidwa ndi magetsi a 12V ndi choyatsira moto, kenako imatumizidwa ku choyatsira moto.
Pogwiritsa ntchito mphamvu yamagetsi amphamvu, mpweya pakati pa elekitirodi yapakati ndi elekitirodi ya mbali ya pulagi ya spark udzakhala ndi ayoni mwachangu, ndikupanga ma ayoni okhala ndi mphamvu zabwino komanso ma elekitironi opanda mphamvu zabwino. Mphamvu yamagetsi pakati pa ma elekitironi ikafika pamtengo winawake, chiwerengero cha ma ayoni ndi ma elekitironi mu mpweya chimawonjezeka ngati chipale chofewa, kotero kuti mpweya umataya mphamvu yake yotetezera, ndipo mpatawo umapanga njira yotulutsira mpweya, zomwe zimapangitsa kuti pakhale "kusweka". Panthawiyi, mpweyawo umapanga thupi lowala, kutanthauza "kusweka". Ndi kukula kwake kwa kutentha, pamakhalanso phokoso la "kugunda". Kutentha kwa mphamvu ya spark iyi kumatha kufika 2000 ~ 3000℃, zomwe ndizokwanira kuyatsa chisakanizocho m'chipinda choyaka cha silinda.
Momwe mungadziwire kuti pulagi ya spark isintha bwanji
Kuti mudziwe ngati pulagi ya spark ikufunika kusinthidwa, mawonekedwe, magwiridwe antchito, ndi nthawi yosinthira pulagi ya spark ingaganizidwe kuchokera mbali zitatu:
Zofunikira pa mawonekedwe a plug ya spark
Wotchi Yopaka Utoto:
Mtundu wamba: chivundikiro cha chotenthetsera cha spark plug chiyenera kukhala cha bulauni kapena choyera pang'ono, kusonyeza kuti kutentha kuli bwino.
chakuda : cholumikizira cha spark ndi chakuda komanso chouma, chomwe chingakhale chosakanikirana kwambiri mu silinda, zomwe zimapangitsa kuti kuyaka kusagwire bwino ntchito.
Choyera: Cholumikizira cha spark ndi choyera, chomwe chingayikidwe molakwika kapena malo osungira mpweya.
Mitundu ina yosazolowereka, monga yofiira kapena dzimbiri, ingasonyeze kuti chotchingira cha spark chili ndi kachilomboka.
Kuwonongeka kwa ma electrode:
Electrode yawonongeka kwambiri kapena yasowa kwathunthu, zomwe zikusonyeza kuti mtunda woyendetsera ndi waukulu ndipo sunasinthidwe kwa nthawi yayitali.
Mkhalidwe wa thupi la ceramic:
Chinthu chachikasu kapena chinthu chonga matope pa thupi la ceramic chingasonyeze kuti mafuta alowa m'chipinda choyaka moto, ndipo ndikofunikira kuyang'ana chisindikizo cha mafuta a valavu ndi zigawo zina.
Njira yowunikira magwiridwe antchito a plug ya Spark
Yambitsani ndi kufulumizitsa : ngakhale njinga yamoto ikayambika bwino, ndikofunikira kuwona ngati kufulumizitsa pamene chitseko cha mafuta chopanda kanthu chili chosalala kuti muweruze momwe plug ya spark plug imagwirira ntchito.
Mphamvu yoyatsira : Mpweya wambiri mu spark plug umakhudza mphamvu yoyatsira, zomwe zimapangitsa kuti pakhale vuto poyambira kapena liwiro losakhazikika.
Kusinthasintha kwa pulagi ya spark
Zipangizo zodziwika bwino: monga pulagi ya nickel alloy spark, tikulimbikitsidwa kuyang'ana makilomita 20,000-30,000, osapitirira makilomita 40,000 kuti musinthe.
Zipangizo zapamwamba kwambiri: monga golide wa iridium, pulagi ya spark ya platinamu, nthawi yosinthira ndi yayitali, nthawi zambiri amalimbikitsidwa kuyang'ana ndikusinthira mu makilomita 40,000-100,000, malinga ndi buku la malangizo agalimoto komanso momwe zinthu zilili.
Zipangizo zogwira ntchito bwino kwambiri: monga pulagi ya iridium spark plug iwiri, kuzungulira kosinthira kumatha kukhala makilomita 100,000 kapena kuposerapo, ndipo ngakhale mitundu ina imatha kufika makilomita 150-200,000.
Chidziwitso *: Kusinthasintha kwa pulagi ya spark kumatha kusiyana kutengera mtundu ndi mtundu wa injini, ndipo tikulimbikitsidwa kuti mugwiritse ntchito malangizo omwe ali m'buku la malangizo a galimoto.
Mwachidule, kuti mudziwe ngati pulagi ya spark ikufunika kusinthidwa, mawonekedwe a mtundu wa pulagi ya spark, kuwonongeka kwa ma electrode, momwe thupi la ceramic lilili, kutalika kwa galimoto ndi mtundu wa injini ziyenera kuganiziridwa mokwanira. Nthawi yomweyo, kuyang'anitsitsa nthawi zonse ndikusintha mapulagi a spark ndikofunikira kwambiri kuti injini igwire bwino ntchito ndikuwonjezera nthawi yogwira ntchito.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zomwe zikulandiridwa kugula.
