Iplagi ekhanyayo, ekwabizwa ngokuba yiplagi ekhanyayo. Iiplagi ezikhanyayo zibonelela ngamandla obushushu bokuqalisa ukusebenza okuphuculweyo xa injini yedizili iphola kubanda kakhulu. Ngelo xesha, iplagi ekhanyayo iyadingeka ukuba ibe neempawu zokunyuka kweqondo lokushisa ngokukhawuleza kunye nokushisa okuphezulu kwexesha elide.

Injini ye-diesel iqala iplagi ekhanyayo
Kukho iintlobo ngeentlobo zeeplagi ezikhanyayo, kwaye okwangoku ezona zisetyenziswa kakhulu zezi zintathu zilandelayo: eziqhelekileyo; Uguqulelo lombane ophantsi we-preheater. Iplagi evuthayo ikrwelwe kudonga lwegumbi lokutsha ngalinye le-injini. Indlu yeplagi ekhanyayo ine-coil ekhanyayo yokumelana neplagi efakwe kwityhubhu. Okwangoku idlula kwikhoyili echasayo, ibangela ukuba ityhubhu ifudumale. I-tube inommandla omkhulu kwaye inokuvelisa amandla amaninzi ashushu. Ingaphakathi lombhobho lizaliswe ngezinto zokukhusela ukukhusela i-coil yokumelana nokudibanisa nodonga lwangaphakathi lombhobho ngenxa yokunyakaza. Ngenxa yamandla ombane ebhetri (i-12V okanye i-24V) kunye nesixhobo sokufudumeza esisetyenzisiweyo, amandla ombane alinganisiweyo kwiiplagi ezikhanyayo ezahlukeneyo nawo ahlukile. Ke ngoko, qiniseka ukusebenzisa uhlobo oluchanekileyo lweeplagi ezikhanyayo. Ukusebenzisa iiplagi ezikhanyayo ezingachanekanga kuya kubangela ukutsha kwangaphambi kwexesha okanye ubushushu obungonelanga.
Kwiinjini ezininzi zedizili, iiplagi ezikhanyayo ezilawulwa ngubushushu ziyasetyenziswa. Olu hlobo lweplagi ekhanyayo luxhotyiswe nge-coil yokufudumala, eneneni iqukethe iikhoyili ezintathu, i-coil yokuthintela, i-coil yokulinganisa kunye ne-coil yokufudumeza ngokukhawuleza, kwaye iikhoyili ezintathu zixhunyiwe kwi-series. Xa umsinga ugqithiswa kwiplagi ekhanyayo, ubushushu bekhoyili yokufudumeza ngokukhawuleza ebekwe kwincam yeplagi ekhanyayo kuqala bunyuke, nto leyo ebangela ukuba iplagi ekhanyayo ibe shushu. Ekubeni ukuchasana kwe-coil yokulinganisa kunye ne-coil yokuthintela kwanda ngokukhawuleza njengoko ukushisa kwe-coil yokufudumeza kwanda, i-current ngokusebenzisa i-coil yokufudumala iyancipha ngokufanelekileyo. Yile ndlela iplagi ekhanyayo ilawula ngayo ubushushu bayo. Ezinye iiplagi ezikhanyayo azinazo iikhoyili ezilinganayo ezifakwe ngenxa yeempawu zazo zokunyuka kobushushu. Iiplagi ezikhanyayo ezilawulwa yiqondo lokushisa ezisetyenziswa kwiiplagi ezintsha ezikhanyayo azifuni izinzwa zangoku, ezenza lula inkqubo yokufudumeza kwangaphambili. [2]
Iplagi ekhanyayo yohlobo lokuhlola isifudumezisi hlela usasazo
Isixhobo sokukhanyisa uhlobo lweplagi ekhanyayo sineeplagi ezikhanyayo, ii-monitor plug ezikhanyayo, iiplagi ezikhanyayo kunye nezinye izinto. Iplagi ekhanyayo ebeka iliso kwideshibhodi ibonisa xa iiplagi ezikhanyayo zishushu.
Iplagi yokubeka iliso ekhanyayo ifakwe kwipaneli yesixhobo ukujonga inkqubo yokufudumeza kweplagi ekhanyayo. Iplagi ekhanyayo ine-resistor eqhagamshelwe kumthombo wamandla ofanayo. Kwaye xa iplagi ekhanyayo ijika ibomvu, lo mxhasi ujika ube bomvu ngexesha elifanayo (ngokuqhelekileyo, i-monitor yeplagi ekhanyayo kufuneka ibe bomvu malunga nemizuzwana eyi-15 ukuya kwe-20 emva kokuba isekethe ivuliwe). Iimonitha ezininzi zeeplagi ezikhanyayo ziqhagamshelwe ngokunxuseneyo. Ke ngoko, ukuba enye yeeplagi ezikhanyayo imfutshane, iplagi ekhanyayo iya kuba bomvu ngaphambili kunesiqhelo. Kwelinye icala, ukuba iplagi ekhanyayo ivulekile, kuya kuthatha ixesha elide ukuba iplagi ekhanyayo ibe bomvu. Ukufudumeza iplagi ekhanyayo ixesha elide kunexesha elichaziweyo kuya konakalisa iplagi ekhanyayo.
Ukuhanjiswa kweplagi ekhanyayo kuthintela inani elikhulu langoku ekudluleni kwi-starter switch kwaye iqinisekisa ukuba i-voltage yehla ngenxa yokukhanya kweplagi ekhanyayo ayiyi kuchaphazela iiplagi ezikhanyayo. Iplagi ekhanyayo ehambisa i-relay eneneni iqulethe iireyidi ezimbini: xa i-starter switch ikwi-G (preheat) indawo, enye i-relay yangoku ngokujonga iplagi ekhanyayo kwiplagi ekhanyayo; xa utshintsho lukwi-START (ukuqala) indawo, enye i-relay. I-relay ihambisa yangoku ngokuthe ngqo kwiplagi ekhanyayo ngaphandle kokungena kwi-monitor yeplagi ekhanyayo. Oku kuthintela iplagi ekhanyayo ukuba ingachatshazelwa kukuhla kwamandla ombane ngenxa yokumelana nokukhanya kweplagi ekhanyayo ngexesha lokuqalisa.
