Kodi choyatsira moto chagalimoto ndi chiyani?
Choyikira cha galimoto ndiye gawo lalikulu la makina oyatsira magetsi a galimoto. Ntchito yake yayikulu ndikusintha mphamvu yamagetsi ya 12V yotsika yamagetsi yoperekedwa ndi batri kukhala magetsi amphamvu mpaka 20,000 mpaka 30,000 volts kudzera mu mfundo yoyatsira magetsi yamagetsi, kupereka mphamvu yofunikira kuti pulagi ya spark iphwanye mu chisakanizo cha mpweya ndi mafuta, motero kuyatsa chisakanizo cha mafuta mu silinda ya injini. Mfundo yake yogwirira ntchito imachokera pa kuyikira kwa magetsi yamagetsi: pamene choyikira chachikulu chimapatsidwa mphamvu kuti chipange mphamvu yamagetsi, ECU (Electronic Control Unit) imalamulira mphamvu yamagetsi kuti idulidwe, ndipo mphamvu yamagetsi imatha mofulumira. Choyikira chachiwiri chimayambitsa mphamvu yamagetsi chifukwa cha kusintha kwa mphamvu yamagetsi. Njirayi iyenera kumalizidwa bwino mkati mwa ma milliseconds kuti zitsimikizire kuti injini ikugwira ntchito bwino komanso mokhazikika.
Chifukwa chomwe choyatsira moto chimatha kusintha magetsi otsika mphamvu pagalimoto kukhala magetsi amphamvu kwambiri ndichakuti chimakhala ndi mawonekedwe ofanana ndi choyatsira moto wamba, ndipo chiŵerengero cha ma turns a choyatsira moto chachikulu ndi chachikulu. Komabe, njira yogwirira ntchito ya choyatsira moto ndi yosiyana ndi ya choyatsira moto wamba. Choyatsira moto wamba chimagwira ntchito mosalekeza, pomwe choyatsira moto chimagwira ntchito mosalekeza. Chimasunga ndi kutulutsa mphamvu mobwerezabwereza pama frequency osiyanasiyana malinga ndi liwiro losiyana la injini.
Pamene cholumikizira choyamba chalumikizidwa ku magetsi, mphamvu yamphamvu ya maginito imapangidwa mozungulira pamene mphamvu ya magetsi ikuwonjezeka, ndipo chitsulo chimasunga mphamvu ya mphamvu ya maginito. Chipangizo chosinthira chikachotsa dera lolumikizira loyamba la cholumikizira, mphamvu ya maginito ya cholumikizira choyamba imawonongeka mofulumira, ndipo mphamvu yamagetsi yapamwamba kwambiri imayambitsidwa mu cholumikizira chachiwiri. Mphamvu yamagetsi ya cholumikizira choyamba ikatha mofulumira, mphamvu yamagetsi imakhala yayikulu panthawi yolumikizira mphamvu yamagetsi, ndipo chiŵerengero cha ma turns a ma coil awiriwa chikakula, mphamvu yamagetsi yomwe imachokera ku cholumikizira chachiwiri imakwera.
Kulephera kugwira ntchito bwino kwa choyikira moto m'galimoto kungayambitse mavuto osiyanasiyana a injini, zomwe zimakhudza chitetezo cha galimoto ndi magwiridwe antchito ake. Zotsatirazi zikufotokoza zinthu monga zizindikiro, zomwe zimayambitsa, kuzindikira ndi kukonza.
Youdaoplaceholder0 Zizindikiro zolakwika: Zizindikiro zodziwika bwino za kulephera kwa coil yoyatsira moto ndi izi:
Youdaoplaceholder0 Kuvuta poyambitsa : Ikayamba kuzizira, injini imangopanga phokoso la "dada" koma imalephera kuyamba, kapena nthawi yoyambira imapitirira masekondi 5.
Kugwedezeka kwa Youdaoplaceholder0 idle: Kugwedezeka kwanthawi zonse kumachitika m'thupi la galimoto, chiwongolero kapena mpando panthawi yogwira ntchito, ndi kusinthasintha kwa liwiro kupitirira ±50rpm.
Youdaoplaceholder0 Kuthamanga kofooka ndi kugwedezeka : Mphamvu imasokonekera mu range ya 2000-3000 RPM. Pali "kugwedezeka" mukakanikiza accelerator mwamphamvu. Mphamvu imatayika mukaidutsa.
Chochitika cha Youdaoplaceholder0 cylinder misfire : Kuwonongeka kwa cylinder ya injini kungayambitse chitoliro chotulutsa utsi kupanga phokoso la "putt-putt", kuwonjezera kugwiritsa ntchito mafuta ndikufulumizitsa mapangidwe a carbon deposits.
Youdaoplaceholder0 Cholakwika chachikulu : Kuwonongeka kwathunthu kwa masilinda payokha kungalepheretse injini kuyambika kapena kupangitsa kuti chosinthira chamagetsi cha njira zitatu chitsekere.
Youdaoplaceholder0 Choyambitsa vuto: Zifukwa zofala zimaphatikizapo:
Youdaoplaceholder0 Kutentha kwambiri ndi zinthu zachilengedwe : kutentha kwambiri kwa injini, malo otentha kwambiri kapena kutentha koipa kungayambitse kukokoloka kwa coil.
Youdaoplaceholder0 Mavuto amagetsi : magetsi amphamvu kwambiri, magetsi otseguka kapena magetsi afupiafupi pansi m'mizere yamagetsi amphamvu, kulephera kwa chowongolera kuyaka.
Vuto la kugwirizana kwa zigawo za Youdaoplaceholder0 : Kuchuluka kwa mpweya woipa, mpata waukulu kwambiri kapena kufupika kwa magetsi pa pulagi ya spark, zomwe zimapangitsa kuti katundu awonjezereke pa coil.
Youdaoplaceholder0 Zolakwika pa khalidwe ndi kukhazikitsa : Kusagwira bwino ntchito kwa coil yokha, kusinthasintha kwa ma turn, kapena kusagwirizana ndi galimoto.
Youdaoplaceholder0 Kusagwira ntchito bwino : kuiwala kuzimitsa choyatsira moto mutayimitsa galimoto kumapangitsa kuti choyimitsacho chitenthe kwambiri chifukwa cha mphamvu yayitali.
Njira zodziwira ndi kuzindikira matenda: zitha kufufuzidwa m'njira zotsatirazi:
Youdaoplaceholder0 Kuwona zizindikiro : Yang'anirani kwambiri zizindikiro zomwe zimachitika kwambiri monga kuvutika kuyamba kuzizira komanso kugwedezeka panthawi yothamanga mwadzidzidzi.
Youdaoplaceholder0 Kuyang'ana kowoneka bwino : Tsegulani chipinda cha injini ndikuwona ngati ma coil ali ndi ming'alu, zizindikiro zamoto kapena madontho a mafuta.
Mayeso a Youdaoplaceholder0 Resistance : Gwiritsani ntchito multimeter kuti muyese kukana kwa coil. Mlingo wabwinobwino wa coil yoyamba ndi 0.5-2Ω, ndipo wa coil yachiwiri, ndi 8-15kΩ.
Kuwerenga kwa khodi ya cholakwika ya Youdaoplaceholder0 OBD : Makhodi olakwika monga P0300 (kulephera kwa silinda mwachisawawa) kapena P0301-P0304 (kulephera kwa silinda yeniyeni) angathandize kupeza vutoli.
Mayeso aukadaulo a Youdaoplaceholder0 : Mlingo wabwinobwino wa mayeso a mphamvu yoyatsira ndi 20-40kV. Ngati ili pansi pa 15kV, coil iyenera kusinthidwa.
Youdaoplaceholder0 Kusamalira ndi njira zodzitetezera: Kusamalira nthawi zonse kumatha kukulitsa moyo wa coil:
Yang'anani mawonekedwe a coil, momwe kulumikizana kulili komanso kusiyana kwa spark plug makilomita 20,000 aliwonse.
Mukasintha ma spark plugs, yang'anani ma coil nthawi imodzi chifukwa nthawi yawo yogwira ntchito ikugwirizana.
Sungani chipinda cha injini chili choyera komanso chouma, ndipo pewani kutsuka mwachindunji mukamatsuka galimoto.
Yambitsani galimotoyo ndipo dikirani kwa masekondi opitilira 30 kuti muchepetse mphamvu ya mphamvu yamagetsi yomwe imachitika nthawi yomweyo.
Gwiritsani ntchito mafuta a octane ofunikira (monga Nambala 95) kuti muchepetse kupanga kwa mpweya woipa.
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.
