Ipulagi yokukhanya ibizwa nangokuthi ipulagi yokushisa kusengaphambili. Uma injini yedizili ipholile ngesikhathi sezulu esibandayo, ipulagi inikeza ukushisa ukuze kuthuthukiswe ukusebenza kokuqala. Ngesikhathi esifanayo, ipulagi kagesi iyadingeka ukuze ibe nezici zokwenyuka kwezinga lokushisa okusheshayo kanye nesimo sokushisa okuphezulu okuqhubekayo.
Izici zepulaki kagesi ehlukahlukene Izici zepulaki kagesi yensimbi · Isikhathi sokushisa kusengaphambili ngesivinini: izinga lokushisa lemizuzwana emi-3 lingafinyelela ngaphezu kwama-degrees Celsius angu-850 · Isikhathi sokushisa ngemva kokushisa: Ngemva kokuqalisa injini, ipulaki igcina izinga lokushisa (850 ° C) imizuzwana eyi-180 ukuze kuncishiswe ukungcola. · Izinga lokushisa lokusebenza: cishe ama-degrees Celsius angu-1000. Izici zepulaki kagesi ye-ceramic · Isikhathi sokushisa: izinga lokushisa lingafinyelela ngaphezu kwama-degrees Celsius angu-900 ngemizuzwana emi-3 · Ngemva kokushisa: Ngemva kokuqalisa injini, ipulaki igcina izinga lokushisa (900 ° C) imizuzwana engu-600 ukuze kuncishiswe ukungcola. Umdwebo weskimu wesakhiwo sepulaki kagesi esivamile · Izinga lokushisa lokusebenza: cishe. 1150 degrees Celsius. Izici zokushisa ipulaki yensimbi ngokushesha · Isikhathi sokushisa: izinga lokushisa lingafinyelela ngaphezu kwama-degree Celsius angu-1000 ngemizuzwana emi-3 · Isikhathi sokushisa ngemva kokushisa: Ngemva kokuqalisa injini, ipulaki igcina izinga lokushisa (1000 ° C) imizuzwana eyi-180 ukunciphisa ukungcola. · Izinga lokushisa lokusebenza: cishe ama-degree Celsius angu-1000 · Ukulawula isignali ye-PWM Izici zokushisa ipulaki ye-ceramic ngokushesha · Isikhathi sokushisa: izinga lokushisa lingafinyelela ngaphezu kwama-degree Celsius angu-1000 ngemizuzwana emi-2 · Isikhathi sokushisa ngemva kokushisa: Ngemva kokuqalisa injini, ipulaki igcina izinga lokushisa (1000 ° C) imizuzwana engama-600 ukunciphisa ukungcola. · Izinga lokushisa lokusebenza: cishe ama-degree Celsius angu-1150 · Ukulawula isignali ye-PWM Ipulaki yokushisa kusengaphambili yokuqala kwenjini yedizili Kunezinhlobo eziningana ezahlukene zamapulaki okushisa kusengaphambili, ezisetshenziswa kakhulu yilezi ezintathu ezilandelayo: ezivamile; Uhlobo lokulawula izinga lokushisa (kufaka phakathi ipulaki yokushisa kusengaphambili yedivayisi yokushisa evamile kanye nedivayisi entsha yokushisa kwangaphambili); Uhlobo lwe-voltage ephansi ye-super preheater evamile. Ipulaki yokushisa kusengaphambili ifakwa esikulufini odongeni ngalunye lwegumbi lokushiswa kwenjini. Indlu yepulaki yokushisa kusengaphambili inekhoyili yokumelana nepulaki yokushisa efakwe epayipini. Ugesi udlula kukhoyili yokumelana, ufudumale ipayipi. Ipayipi inendawo enkulu futhi ingakhiqiza ukushisa okwengeziwe. Ipayipi ligcwele izinto zokuvikela ukuvimbela ikhoyili yokumelana ukuthi ingathintani nodonga lwangaphakathi lwepayipi ngenxa yokudlidliza. I-voltage elinganisiwe yamapulaki ahlukahlukene okushisa kusengaphambili iyahlukahluka kuye nge-voltage yebhethri esetshenzisiwe (12V noma 24V) kanye nedivayisi yokushisa kusengaphambili. Ngakho-ke, kubalulekile ukusebenzisa uhlobo olufanele lwepulaki yokushisa kusengaphambili, ukusetshenziswa kwepulaki yokushisa kusengaphambili engalungile kuzoba ukushisa kwangaphambi kwesikhathi noma ukushisa okwanele. Izinga lokushisa - ipulaki yokushisa elawulwayo isetshenziswa ezinjinini eziningi zedizili. Ipulaki yokushisa kusengaphambili ifakwe ikhoyili yokushisa, empeleni eyakhiwe ngamakhoyili amathathu - ikhoyili yebhloko, ikhoyili yokulinganisa kanye nekhoyili yentambo eshisayo - ngokulandelana. Uma ugesi udlula epulakini yokushisa kwangaphambilini, izinga lokushisa lendandatho yentambo eshisayo etholakala esicongweni sepulakini yokushisa kwangaphambilini likhuphuka kuqala, okwenza ipulakini yokushisa kwangaphambilini ikhanye. Njengoba ukumelana kwe-coil yokulinganisa kanye ne-coil yokubamba kukhuphuka kakhulu ngokushisa kwe-coil yokucima, ugesi ogeleza nge-coil yokucimani uyancipha. Ngakho-ke ipulakini yokushisa kwangaphambilini ilawula izinga lokushisa layo. Amanye amapulakini okushisa kwangaphambilini awanawo ama-coil okulinganisa ngenxa yezici zawo zokuphakama kokushisa. Uhlobo olusha lwepulakini yokushisa kwangaphambilini elawulwa izinga lokushisa aludingi inzwa yamanje, okwenza kube lula uhlelo lokushisa kwangaphambilini. [2]Idivayisi yokushisa kwangaphambilini yohlobo lwe-preheating plug monitor Uhlobo lwe-preheating plug monitor Uhlobo lwe-preheating plug monitor Uhlobo lwe-preheating plug monitor luqukethe ipulakini yokushisa kwangaphambilini, i-preheating plug monitor, i-preheating plug relay nezinye izingxenye. Lapho ipulakini yokushisa kwangaphambilini ishisa, i-preheating plug monitor kuphaneli yezinsimbi izoboniswa. I-preheating plug monitor ifakwe kuphaneli yezinsimbi ukuze iqaphe inqubo yokushisa yepulakini yokushisa kwangaphambilini. Ipulakini yokushisa kwangaphambilini ine-resistor exhunywe kugesi ofanayo. Futhi uma ipulaki ye-preheater iba bomvu, le resistor nayo iba bomvu (ngokuvamile, i-preheater plug monitor kufanele ikhanye ibe bomvu cishe imizuzwana eyi-15 kuya kwengama-20 ngemva kokuthi isekethe ivuliwe). Ama-preheat plug monitor amaningana axhunywe ngokuhambisana. Ngakho-ke, uma ipulaki ye-preheat ifinyelelwe, i-preheat plug monitor izobomvu ngaphambi kwesikhathi esijwayelekile. Ngakolunye uhlangothi, uma ipulaki ye-preheater inqanyuliwe, kuthatha isikhathi eside ukuthi i-preheat plug monitor ibe bomvu. Ukushisa ipulaki ye-preheater isikhathi eside kunesikhathi esibekiwe kuzolimaza i-preheat plug monitor. I-preheat plug relay ivimbela ugesi oweqile ukuthi ungadluli ku-starter switch futhi iqinisekisa ukuthi ipulaki ye-preheat ngeke ithintwe ukwehla kwamandla kagesi okubangelwa yi-preheat plug monitor. I-preheat plug relay empeleni inama-relay amabili: lapho i-starter switch isesimweni se-G(preheating), ugesi we-relay eyodwa udlula ku-preheating plug monitor uye ku-preheating plug; Uma i-switch isesimweni se-START, enye i-relay ithumela ugesi ngqo ku-preheat plug ngaphandle kokudlula ku-preheat plug monitor. Lokhu kugwema ukwehla kwamandla kagesi ngenxa yokumelana kwe-preheating plug monitor ngesikhathi sokuqalisa okungathinta i-preheating plug.
