Iplagi yokukhanya, eyaziwa ngokuba yiplagi yokukhanya. Iiplagi zokukhanya zibonelela ngamandla obushushu ukuze kuphuculwe ukusebenza kokuqala xa injini yedizili iphola xa kubanda kakhulu. Kwangaxeshanye, iplagi yokukhanya iyadingeka ukuba ibe neempawu zokunyuka ngokukhawuleza kobushushu kunye nemeko yobushushu obuphezulu ehlala ixesha elide.

Iplagi yokukhanya yokuqalisa injini yedizili
Kukho iintlobo ezahlukeneyo zeeplagi zokukhanya, kwaye okwangoku ezona zisetyenziswa kakhulu zezi zintathu zilandelayo: eziqhelekileyo; Uhlobo lwe-voltage ephantsi ye-preheater. Iplagi yokukhanya ifakwa kwiikrufu kudonga ngalunye lwegumbi lokutsha lwenjini. Indlu yeplagi yokukhanya ine-coil ye-glow plug resistor efakwe kwityhubhu. Umbane udlula kwi-coil ye-resistive, nto leyo ebangela ukuba ityhubhu ifudumale. Ityhubhu inendawo enkulu kwaye inokuvelisa amandla obushushu amaninzi. Ingaphakathi letyhubhu lizaliswe zizinto zokuthintela ukuthintela i-resistance coil ukuba ingadibani nodonga lwangaphakathi lwetyhubhu ngenxa yokungcangcazela. Ngenxa yevolthi yebhetri eyahlukileyo (12V okanye 24V) kunye nesixhobo sokufudumeza esisetyenzisiweyo, ivolthi elinganisiweyo yeeplagi zokukhanya ezahlukeneyo nayo yahlukile. Ke ngoko, qiniseka ukuba usebenzisa uhlobo oluchanekileyo lweeplagi zokukhanya. Ukusebenzisa iiplagi zokukhanya ezingalunganga kuya kubangela ukutsha kwangaphambi kwexesha okanye ubushushu obaneleyo.
Kwiinjini ezininzi zedizili, kusetyenziswa iiplagi zokukhanya ezilawulwa bubushushu. Olu hlobo lweplagi yokukhanya luxhotyiswe nge-heating coil, eneneni equlathe ii-coil ezintathu, i-blocking coil, i-equalizing coil kunye ne-rapid heating coil, kwaye ezi coil zintathu ziqhagamshelwe ngokulandelelana. Xa umbane udlula kwi-glow plug, ubushushu be-rapid heating coil ekwincam ye-glow plug buqala bunyuke, nto leyo ebangela ukuba i-glow plug ikhanye kakhulu. Ekubeni ukumelana kwe-equalizing coil kunye ne-blocking coil kuyanda ngokukhawuleza njengoko ubushushu be-heating coil bunyuka, umbane nge-heating coil uyancipha ngokufanelekileyo. Le yindlela i-glow plug elawula ngayo ubushushu bayo. Ezinye iiplagi zokukhanya azinazo ii-equalizing coils ezifakiweyo ngenxa yeempawu zazo zokunyuka kobushushu. Iiplagi zokukhanya ezilawulwa bubushushu ezisetyenziswa kwiiplagi ezintsha ze-super glow azifuni zinzwa zangoku, nto leyo eyenza kube lula inkqubo yokufudumeza kwangaphambili. [2]
Usasazo lokujonga iplagi yokukhanya uhlobo lweheater elungisiweyo
Isixhobo sokukhanya sohlobo lwe-glow plug monitor siquka ii-glow plugs, ii-glow plug monitors, ii-glow plug relays kunye nezinye izinto. I-glow plug monitor kwideshibhodi ibonisa xa ii-glow plugs zishushu.
Isikrini seplagi yokukhanya sifakwa kwipaneli yesixhobo ukuze kujongwe inkqubo yokufudumeza yeplagi yokukhanya. Iplagi yokukhanya ine-resistor eqhagamshelwe kumthombo wamandla ofanayo. Kwaye xa iplagi yokukhanya ijika ibe bomvu, le resistor nayo ijika ibe bomvu ngaxeshanye (ngesiqhelo, isikrini seplagi yokukhanya kufuneka sikhanye bomvu malunga nemizuzwana eli-15 ukuya kwengama-20 emva kokuba isekethe ivuliwe). Iimonitha ezininzi zeplagi yokukhanya ziqhagamshelwe ngaxeshanye. Ke ngoko, ukuba enye yeeplagi zokukhanya imfutshane, isikrini seplagi yokukhanya siya kuba bomvu ngaphambi kwexesha eliqhelekileyo. Kwelinye icala, ukuba iplagi yokukhanya ivuliwe, kuya kuthatha ixesha elide ukuba isikrini seplagi yokukhanya sikhanye bomvu. Ukufudumeza iplagi yokukhanya ixesha elide kunexesha elichaziweyo kuya konakalisa isikrini seplagi yokukhanya.
I-glow plug relay ithintela umbane omkhulu ukuba ungadluli kwi-starter switch kwaye iqinisekisa ukuba ukwehla kwe-voltage ngenxa ye-glow plug monitor akuyi kuchaphazela ii-glow plugs. I-glow plug relay inee-relay ezimbini: xa i-starter switch ikwindawo ye-G (preheat), enye i-relay current idlula kwi-glow plug monitor ukuya kwi-glow plug; xa i-switch ikwindawo ye-START (start), enye i-relay. I-relay ihambisa umbane ngqo kwi-glow plug ngaphandle kokudlula kwi-glow plug monitor. Oku kuthintela i-glow plug ukuba ingachaphazeleki kukwehla kwe-voltage ngenxa yokumelana kwe-glow plug monitor ngexesha lokuqalisa.
