Ignition coil.
Hamwe niterambere rya moteri ya lisansi yimodoka yerekeza ku muvuduko wihuse, igipimo kinini cyo kugabanuka, ingufu nyinshi, gukoresha peteroli nkeya hamwe n’ibyuka bihumanya ikirere, ibikoresho gakondo byo gutwika ntibyashoboye kuzuza ibisabwa kugirango bikoreshwe. Ibyingenzi bigize igikoresho cyo gutwika ni coil yo gutwika hamwe nigikoresho cyo guhinduranya, kunoza ingufu za coil yo gutwika, icyuma gishobora kubyara ingufu zihagije, nicyo kintu cyibanze cyibikoresho byo gutwika kugirango gihuze n'imikorere ya moteri zigezweho .
ihame
Mubisanzwe hariho ibice bibiri bya coil imbere muri coil yo gutwika, coil primaire na coil ya kabiri. Igiceri cyibanze gikoresha insinga nini cyane, mubisanzwe hafi ya mm 0,5-1 mm yashizwemo hafi ya 200-500; Igiceri cya kabiri gikoresha insinga yoroheje cyane, ubusanzwe insinga zigera kuri 0.1 mm zometse kuri 15000-25000. Impera imwe ya coil ibanza ihujwe n’amashanyarazi make (+) ku kinyabiziga, naho iyindi ihujwe nigikoresho cyo guhinduranya (breaker). Impera imwe ya coil ya kabiri ihujwe na coil primaire, naho iyindi mpera ihujwe nibisohoka byanyuma byumurongo wa voltage mwinshi kugirango bisohore ingufu nyinshi.
Impamvu ituma igicanwa cyo gutwika gishobora guhindura voltage ntoya mumashanyarazi menshi kumodoka nuko ifite imiterere imwe na transformateur isanzwe, kandi coil primaire ifite igipimo kinini cyo guhinduka kuruta coil ya kabiri. Ariko uburyo bwo gutwika coil bwo gukora butandukanye na transformateur isanzwe, transformateur isanzwe ikora inshuro 50Hz, bizwi kandi nka power frequency transformer, kandi coil yo gutwika iri muburyo bwimirimo ya pulse, irashobora gufatwa nkimpinduka ya pulse, ukurikije umuvuduko utandukanye wa moteri kumurongo utandukanye wo kubika ingufu no gusohora.
Iyo coil primaire ikoreshwa, umurima ukomeye wa magneti ubyara hafi yacyo uko umuyaga wiyongera, kandi ingufu za magnetique zibikwa mumyuma. Iyo igikoresho cyo guhinduranya gihagaritse uruziga rwibanze, umurima wa magneti wa coil primaire ubora vuba, kandi coil ya kabiri ikumva voltage nini. Umuvuduko ukabije wa magnetiki ya coil primaire irazimangana, niko bigenda bihinduka mugihe cyo gutandukana kwubu, kandi niko igipimo kinini cyo guhinduranya ibiceri byombi, niko nini ya voltage iterwa na coil ya kabiri.
Ubwoko bw'igiceri
Ignition coil ukurikije umuzenguruko wa magneti igabanijwemo ubwoko bwa magnetiki bwuguruye nubwoko bwa magneti bufunze. Igiceri gakondo cyo gutwika ni ubwoko bwa magnetiki bwuguruye, kandi icyuma cyacyo gishyizwe hamwe n'amabati ya 0.3mm ya silicon, kandi hariho ibiceri bya kabiri kandi byibanze bikikije icyuma. Ubwoko bwa magnetiki bufunze bukoresha icyuma gisa na Ⅲ hafi ya coil primaire, hanyuma ugahindura coil ya kabiri hanze, hanyuma umurongo wa magnetiki ugizwe nicyuma. Ibyiza bya gufunga magnetiki yo gufunga ni gake ya magnetique yamenetse, gutakaza ingufu nkeya nubunini buto, sisitemu yo gutwika elegitoronike muri rusange ikoresha igifuniko cya magneti gifunze.
Kugenzura umubare
Muri moteri yihuta ya moteri yimodoka igezweho, sisitemu yo gutwika igenzurwa na microprocessor, izwi kandi nka sisitemu yo gutwika ibyuma bya elegitoroniki. Sisitemu yo gutwika igizwe n'ibice bitatu: microcomputer (mudasobwa), sensor zitandukanye hamwe na moteri ikora.
Mubyukuri, muri moteri zigezweho, inshinge za lisansi hamwe na sisitemu yo gutwika bigenzurwa na ECU imwe, isangiye ibice bya sensor. Rukuruzi irasa cyane na sensor muri sisitemu yo guterwa na lisansi igenzurwa na elegitoronike, nka sensor ya poste ya crankshaft, sensor ya posita ya sensor, trottle position sensor, gufata ibyuma byinshi byumuvuduko, sensor ya dedetonation, nibindi. Muri byo, sensor ya dedetonation ni cyane icyuma cyingenzi kigenewe gutwikwa hakoreshejwe uburyo bwa elegitoronike (cyane cyane moteri ifite gaze ya gaz turbucarike ya gaze), ishobora kugenzura niba moteri ya moteri na degetonation, nkikimenyetso cyo gutanga ibitekerezo kugirango ECU itegeko ryo kugera ku gucana hakiri kare, kugirango moteri itazitangira kandi ishobora kubona umuriro mwinshi.
Sisitemu ya elegitoroniki yo gutwika (ESA) igabanijwemo ubwoko bubiri ukurikije imiterere yabyo: ubwoko bwabakwirakwiza nubwoko butagabura (DLI). Ikwirakwizwa ryubwoko bwa elegitoronike ikoresha sisitemu imwe yo gutwika kugirango itange ingufu nyinshi, hanyuma uyikwirakwiza akongeza icyuma cya buri silinderi mugihe gikurikiranye. Kubera ko imirimo yo guhagarika igiceri cyibanze cya coil yo gutwika ikorwa numuzunguruko wa elegitoronike, uwagabanije yahagaritse igikoresho kimena kandi akina gusa umurimo wo gukwirakwiza amashanyarazi menshi.
Amashanyarazi abiri
Gutwika silindiri ebyiri bivuze ko silindiri ebyiri zisangiye igiceri kimwe cyo gutwika, ubwo buryo bwo gutwika rero bushobora gukoreshwa gusa kuri moteri hamwe numubare wa silinderi. Niba kuri mashini ya silindari 4, mugihe piston ebyiri za silinderi zegeranye na TDC icyarimwe (imwe ni compression naho indi irarangiye), ibyuma bibiri bya spark bisangiye igiceri kimwe cyo gutwika icyarimwe, noneho kimwe kirakora gutwika naho ubundi ni ugutwika ubusa, iyambere iri muruvange rwumuvuduko mwinshi nubushyuhe buke, iyanyuma iri muri gaze ya gaze yumuvuduko muke nubushyuhe bwinshi. Kubwibyo, kurwanya hagati ya spark plug electrode ya byombi biratandukanye rwose, kandi ingufu zakozwe ntizimeze kimwe, bivamo ingufu nini cyane zo gutwika neza, bingana na 80% byingufu zose.
Gutandukanya
Uburyo butandukanye bwo gutwika butanga igiceri cyo gutwika kuri buri silinderi, kandi igiceri cyo gutwika gishyirwa hejuru yicyuma cya spark, nacyo gikuraho insinga nini ya voltage. Ubu buryo bwo gutwika bugerwaho na sensor ya camshaft cyangwa mugukurikirana compression ya silinderi kugirango igere ku muriro nyawo, irakwiriye kuri moteri iyo ari yo yose ya moteri, cyane cyane kuri moteri ifite valve 4 kuri silinderi. Kuberako spark plug ignition coil guhuza irashobora gushirwa hagati ya camshaft ya kabiri yo hejuru (DOHC), umwanya wicyu urakoreshwa rwose. Bitewe n'iseswa ry'abakwirakwiza n'umurongo wa voltage mwinshi, gutakaza ingufu zo gutwara no gutakaza ni bike, nta kwambara imashini, kandi coil yo gutwika hamwe na spark plug ya buri silinderi ikusanyirizwa hamwe, kandi icyuma cyo hanze kigabanya cyane u kwivanga kwa electromagnetic, bishobora kwemeza imikorere isanzwe ya sisitemu yo kugenzura moteri.
