Ipulaki ekhanyayo ibizwa nangokuthi ipulaki yokushisisa.Uma injini yedizili ipholiswa ngesikhathi sezulu esibandayo, ipulaki inikeza ukushisa ukuze kuthuthukiswe ukusebenza kokuqala.Ngesikhathi esifanayo, ipulaki kagesi iyadingeka ukuze ibe nezici zokukhuphuka kwezinga lokushisa ngokushesha kanye nesimo sokushisa esiphezulu esiqhubekayo.
Izici zepulaki kagesi ehlukahlukene Izici zepulaki kagesi yensimbi· Isikhathi sokushisa ngaphambi kwesikhathi: imizuzwana emi-3 izinga lokushisa lingafinyelela ngaphezu kwama-degree Celsius angu-850 · Isikhathi sokushisisa ngemva kokuqalisa kwenjini, ipulaki igcina izinga lokushisa (850 ° C) imizuzwana engu-180 ukuze kuncishiswe ukungcola.· Izinga lokushisa elisebenzayo: cishe ngu-1000 degrees Celsius.Izici zepulaki likagesi kagesi · Isikhathi sokushisa: izinga lokushisa lingafinyelela ngaphezu kwama-degree Celsius angu-900 ngemizuzwana emi-3 · Isikhathi sokushisisa ngemva kokuqalisa kwenjini, ipulaki ligcina izinga lokushisa (900 ° C) imizuzwana engu-600 ukuze linciphise. ukungcola.Umdwebo ohleliwe wesakhiwo sepulaki kagesi esivamile · Izinga lokushisa elisebenzayo: cishe.1150 degrees Celsius.Ukushisisa kwangaphambilini okusheshayo kwezici zepulagi yensimbi· Isikhathi sokushisa: izinga lokushisa lingafinyelela ngaphezu kuka-1000 degrees Celsius ngemizuzwana emi-3· Isikhathi sokufudumeza okuthunyelwe: Ngemva kokuba injini iqalile, ipulaki igcina izinga lokushisa (1000 ° C) imizuzwana engu-180 ukunciphisa ukungcola. .· Izinga lokushisa elisebenzayo: cishe ngu-1000 degrees Celsius · Ukulawula isignali ye-PWM Izici zepulagi ye-ceramic yokushisisa kuqala kusengaphambili· Isikhathi sokushisa: izinga lokushisa lingafinyelela ngaphezu kuka-1000 degrees Celsius ngemizuzwana engu-2 · Isikhathi sokushisisa ngemva kokuqalisa kwenjini, ipulaki igcina izinga lokushisa (1000 ° C) imizuzwana engu-600 ukunciphisa ukungcola.· Izinga lokushisa elisebenzayo: cishe.1150 degrees Celsius · I-PWM yokulawula isignali Injini ye-diesel iqala ukushisa ipulaki Kunezinhlobo eziningana zamapulaki okushisa, asetshenziswa kakhulu yilezi ezintathu ezilandelayo: evamile;Uhlobo lokulawula izinga lokushisa (okuhlanganisa ipulaki yokushisisa kusengaphambili yedivayisi evamile yokushisa kuqala kanye nedivayisi entsha yokushisa kuqala);Uhlobo lwe-voltage ephansi ye-super preheater evamile.Ipulaki yokushisisa ngaphambili ifakwe odongeni lwegumbi elivuthayo ngalinye lenjini.Indlu yepulaki yokushisisa ngaphambili inekhoyili yokumelana nepulaki elishisa ngaphambili elifakwe eshubhu.Umsinga kagesi udlula ikhoyili yokumelana, ushisa ithubhu.Ishubhu inendawo enkulu futhi ingakhiqiza ukushisa okwengeziwe.Ishubhu igcwele insulating impahla ukuvimbela ikhoyili ukumelana ukuthintana nodonga lwangaphakathi tube ngenxa vibration.I-voltage elinganisiwe yamapulaki okushisa ahlukahlukene ayahlukahluka kuye ngokuthi ibhethri lisetshenziswa kanjani (12V noma 24V) kanye nedivayisi yokushisa kuqala.Ngakho-ke, kubalulekile ukusebenzisa uhlobo olufanele lwepulaki yokushisa, ukusetshenziswa kwepulaki yokushisa engalungile kuyoba ukusha ngaphambi kwesikhathi noma ukushisa okwanele.Izinga lokushisa - ipulaki yokushisa elawulwayo isetshenziswa ezinjini eziningi zedizili.Ipulaki yangaphambi kokushisa ifakwe ikhoyili yokushisa, empeleni eyakhiwe ngamakhoyili amathathu - i-block coil, ikhoyili yokulinganisa kanye ne-hot wire coil - ngochungechunge.Lapho i-current idlula kupulaki yokushisisa ngaphambili, izinga lokushisa lendandatho yentambo eshisayo etholakala ekugcineni kwepulaki yokushisa ngaphambilini liyakhuphuka kuqala, okwenza ipulaki yokushisa iqale incandescent.Njengoba ukumelana kwekhoyili yokulinganisa kanye nekhoyili yokubopha kukhula kakhulu ngokushisa kwekhoyili yokucisha, lamanje eligeleza ikhoyili yokucisha liyehla.Ngakho ipulaki yokushisisa ilawula izinga lokushisa layo.Amanye amapulaki ashisayo awanawo amakhoyili okulinganisa ngenxa yezimpawu zawo zokukhuphuka kwezinga lokushisa.Uhlobo olusha lwepulaki yokushisa elawulwa izinga lokushisa alidingi inzwa yamanje, eyenza isistimu yokushisa ibe lula.[2]Idivayisi yohlobo lokuhlola ipulaki eshisa kuqala Idivayisi yohlobo lwepulaki yokuqapha ukushisa kuqala iqukethe ipulaki eshisa ngaphambili, isiqaphi sepulaki elishisa ngaphambili, ipulaki elidluliswayo elishisayo nezinye izingxenye.Uma ipulaki ye-preheater ishisa, ipulaki yepulaki yangaphambi kokushisa izoboniswa kuphaneli yensimbi.Ipulaki yokushisa yangaphambi kwesikhathi ifakwe kuphaneli yensimbi ukuze kuqashwe inqubo yokushisisa yepulaki yokushisisa ngaphambilini.Ipulaki ye-preheater ine-resistor exhunywe kugesi ofanayo.Futhi lapho ipulaki ye-preheater iba bomvu, lesi sici esiphikisayo siphinde sibe bomvu (ngokuvamile, ipulaki yepulaki ye-preheater kufanele ikhanye ngokubomvu cishe imizuzwana engu-15 ukuya kwangu-20 ngemva kokuvulwa kwesekhethi).Amapulaki amaningana amapulaki okushisa axhunyiwe ngokuhambisana.Ngakho-ke, uma ipulaki yokushisa ngaphambi kwesikhathi ine-circuited, ipulaki yepulaki yokushisa izoba bomvu ngaphambi kwesikhathi esivamile.Ngakolunye uhlangothi, uma ipulaki ye-preheater inqanyulwa, kuthatha isikhathi eside ukuthi ipulaki yepulaki yangaphambi kokushisa ibe bomvu.Ukushisisa ipulaki ye-preheater isikhathi eside kunesikhathi esishiwo kuzolimaza ipulaki yepulaki yangaphambi kokushisa.Ipulaki edluliselwe ngaphambili ivimbela amandla amaningi ukuba ingadluli kusiqalisi futhi iqinisekisa ukuthi ipulaki yokushisa ngaphambi kwesikhathi ngeke ithikamezeke ukwehla kwamandla kagesi okubangelwa isiqaphali sepulaki yangaphambi kokushisa. .I-preheating plug relay empeleni iqukethe ama-relay amabili: lapho iswishi yesiqalisi isendaweni ye-G(preheating), i-current ye-relay eyodwa idlula kumonitha yepulaki yokushisisa ngaphambili iye kupulaki yokushisisa ngaphambilini;Uma iswishi isendaweni ethi START, enye i-relay ithumela okwamanje ngokuqondile kupulaki yokushisisa kuqala ngaphandle kokudlula kumonitha wepulaki yangaphambi kokushisa.Lokhu kugwema ukwehla kwe-voltage ngenxa yokumelana ne-monitor yepulaki yokushisisa ngesikhathi sokuqalisa okungathinta ipulaki yokushisa.
