Iplagi ekhanyayo ikwabizwa ngokuba yiplagi yokufudumeza.Xa i-injini ye-diesel ipholile ngexesha lemozulu ebandayo, iplagi inika ubushushu ukuphucula ukusebenza kokuqala.Ngelo xesha, iplagi yombane iyadingeka ukuba ibe neempawu zokunyuka kweqondo lokushisa ngokukhawuleza kunye nobushushu obuphezulu obuqhubekayo.
Iimpawu zeeplagi zombane ezahlukeneyo Iimpawu zeplagi yombane · Ixesha lokufudumeza ngesantya: imizuzwana emi-3 ubushushu bunokufikelela ngaphezu kwama-850 degrees Celsius · Ixesha lokufudumeza emva kokuqalisa: Emva kokuba injini iqalile, iplagi igcina ubushushu (850 ° C) imizuzwana eyi-180 ukunciphisa ungcoliseko.· Ubushushu bokusebenza: malunga ne-1000 degrees Celsius. Iimpawu zeplagi yombane ngeCeramic · Ixesha lokufudumeza: ubushushu bunokufikelela ngaphezulu kwama-900 degrees celcius kwimizuzwana emi-3 · Ixesha lokufudumeza emva kokuqalisa kwe-injini, iplagi igcina ubushushu (900 ° C) imizuzwana engama-600 ukunciphisa ungcoliseko.Umzobo weSchematic wesakhiwo seplagi yombane eqhelekileyo· Ubushushu bokusebenza: malunga.I-1150 degrees Celsius. Ukufudumeza ngokukhawuleza kweempawu zeplagi yentsimbi· Ixesha lokufudumeza: ubushushu bunokufikelela ngaphezu kwe-1000 ngokukaCelsius kwimizuzwana emi-3· Ixesha lokufudumeza emva kokuba injini iqalile, iplagi igcina ubushushu (1000 ° C) imizuzwana eyi-180 ukunciphisa ungcoliseko. .· Ubushushu bokusebenza: malunga ne-1000 degrees Celsius · Ulawulo lwesignali yePWM yokufudumeza ngokukhawuleza kweplagi yeceramic ekhawulezayo C) imizuzwana engama-600 ukunciphisa ungcoliseko.· Ubushushu bokusebenza: malunga.I-1150 degrees Celsius · Ulawulo lwesignali yePWM Injini yedizili iqala ukufudumeza iplagi Kukho iintlobo ezininzi ezahlukeneyo zeeplagi zokufudumeza, ezona zisetyenziswa kakhulu zezi zintathu zilandelayo: rhoqo;Uhlobo lokulawula ubushushu (kubandakanywa iplagi yokufudumeza kwangaphambili kwisixhobo esiqhelekileyo sokufudumeza kunye nesixhobo esitsha sokufudumeza okuphezulu);Uhlobo lombane ophantsi lwe-preheater eqhelekileyo.Iplagi yokufudumeza kwangaphambili ikrwelwe kudonga lwegumbi lokutsha ngalinye le-injini.I-preheating plug housing ine-coil yokumelana ne-preheating iplagi efakwe kwi-tube.Umbane wombane udlula kwi-coil yokumelana, ukufudumala ityhubhu.Umbhobho unomhlaba omkhulu kwaye unokuvelisa ubushushu obuninzi.I-tube igcwele izinto zokukhusela ukukhusela i-coil yokumelana nokudibanisa nodonga lwangaphakathi lombhobho ngenxa yokunyakaza.I-voltage elinganisiweyo yeeplagi zokufudumeza ezahlukeneyo ziyahluka ngokuxhomekeke kumbane webhetri osetyenzisiweyo (12V okanye i-24V) kunye nesixhobo sokufudumeza kwangaphambili.Ngoko ke, kubalulekile ukusebenzisa uhlobo oluchanekileyo lweplagi yokutshisa iplagi, ukusetyenziswa kweplagi yokutshisa i-preheating engalunganga iya kuba ngumlilo wangaphambi kwexesha okanye ukushisa okunganeleyo.Ubushushu - iplagi yokufudumala elawulwayo isetyenziswe kwiinjini ezininzi ze-diesel.Iplagi yokutshisa i-preheating ifakwe i-coil yokufudumeza, eyona nto iqulethwe ngamatye amathathu - i-block coil, i-coil yokulinganisa kunye ne-coil yocingo eshushu - kwi-series.Xa i-current idlula kwiplagi yokufudumala, ubushushu bendandatho yocingo olushushu olubekwe kwincam yeplagi yokufudumeza iphakama kuqala, yenza iplagi yokutshisa i-incandescent.Njengoko ukuchasana kwekhoyili yokulinganisa kunye nokubanjwa kwekhoyili kwanda ngokukhawuleza kunye nokushisa kwe-coil yokucima, i-current flowing ngokusebenzisa i-coil yokucima iyancipha.Iplagi yokufudumeza ngoko ilawula ubushushu bayo.Ezinye iiplagi zokufudumeza azinazo iikhoyili zokulinganisa ngenxa yeempawu zabo zokunyuka kobushushu.Uhlobo olutsha lobushushu obulawulwayo kwiplagi yokufudumeza ayifuni inzwa yangoku, eyenza lula inkqubo yokufudumeza.[2]Iplagi yokufudumeza iplagi yodidi olufudumezayo uhlobo lwesixhobo sokufudumeza iplagi yohlobo lokufudumeza kwangaphambili isixhobo sineplagi yokufudumeza, iplagi yokufudumeza kwangaphambili, iplagi yokufudumeza kwangaphambili kunye nezinye izinto.Xa iplagi ye-preheater itshisa, iplagi yokushisa iplagi ye-preheater kwipaneli yesixhobo iya kuboniswa.I-monitor yeplagi yokufudumeza ifakwe kwisixhobo sokulawula inkqubo yokufudumeza iplagi yokufudumeza kwangaphambili.Iplagi ye-preheater ine-resistor eqhagamshelwe kunikezelo lwamandla olufanayo.Kwaye xa iplagi ye-preheater ijika ibomvu, esi sixhasi sijika sibe bomvu (ngokwesiqhelo, iplagi yokujongisisa kwangaphambili kufuneka ikhazimle bomvu malunga nemizuzwana eyi-15 ukuya kwengama-20 emva kokuba isekethe ilayitiwe).Iimonitha ezininzi zeeplagi ze-preheat preheat ziqhagamshelwe ngokufanayo.Ngoko ke, ukuba iplagi yokutshisa i-preheat ifutshane-ijikelezwe, i-monitor yeplagi ye-preheat iya kuba bomvu ngaphambili kunesiqhelo.Kwelinye icala, ukuba iplagi ye-preheater ivaliwe, kuthatha ixesha elide ukuba iplagi yeplagi yangaphambili ijike ibebomvu.Ukufudumeza iplagi ye-preheater ixesha elide kunexesha elichaziweyo kuya konakalisa iplagi ye-preheat plug esweni.I-preheat plug relay inqanda ukugqithiswa kwangoku ekudluleni kwi-starter switch kwaye iqinisekisa ukuba iplagi ye-preheat ayiyi kuchaphazeleka kukuhla kwamandla ombane okubangelwa yi-preheat plug monitor. .I-preheating plug relay eneneni iqulethe iireyidi ezimbini: xa i-starter switch ikwi-G (preheating) kwindawo, i-current ye-relay enye idlula kwi-monitor yeplagi yokufudumeza ukuya kwiplagi yokufudumeza kwangaphambili;Xa umtshintshi ukwi-START indawo, enye i-relay ithumela ngoku ngqo kwiplagi ye-preheat ngaphandle kokudlula kwi-monitor yeplagi ye-preheat.Oku kunqanda ukuhla kombane ngenxa yokuchasana kweplagi yokutshisa iplagi ngexesha lokuqalisa eliya kuchaphazela iplagi yokufudumeza.
