Umgomo wokusebenza wepulaki ye-preheater yemoto
Isimiso sokusebenza sepulaki yokushisisa ngaphambili kwemoto sisekelwe kakhulu kumphumela wokushisa kagesi . Ipulaki yokushisa ngaphambi kokushisa ixhunywe kusixhumi esiseceleni sekhondatha yeyunithi (GCU) ukuze sinikeze amandla kagesi epulaki yokushisa kagesi. Ngemva kokuthola amandla kagesi, intambo yokushisa kagesi ngaphakathi kwepulaki kagesi izoshisa ngokushesha, futhi idlulisele amandla okushisa emoyeni ekamelweni elivuthayo lenjini ye-diesel, ngaleyo ndlela ikhulise izinga lokushisa lomoya, okwenza uwoyela wedizili uvutha kalula. , kanye nokwenza ngcono ukusebenza kokuqala okubandayo kwenjini kadizili.
Umsebenzi oyinhloko wepulaki yokushisa
Umsebenzi oyinhloko wepulaki yokushisa ukushisa ukunikeza amandla okushisa ngenkathi injini yedizili ipholisa ukuthuthukisa ukusebenza kokuqala. Ukuze ufeze le njongo, ipulaki yokushisa idinga ukuba nezici zokushisa okusheshayo nokushisa okuphezulu okuqhubekayo. Uma injini ye-diesel isendaweni ebandayo, ipulaki yokushisa ngaphambi kwesikhathi inganikeza amandla okushisa futhi isize ukuthuthukisa ukusebenza kokuqala.
Izimpawu nezindlela zokuhlola zamapulaki okushisa
Lapho ehlola isimo sokusebenza sepulaki yangaphambi kokushisa, uchwepheshe uzoxhuma isibani sokuhlola kutheminali ye-G1 yesixhumi eseceleni somqhubi we-GCU, bese enqamula ikhebula kusixhumi samandla sepulaki yokushisa kagesi eyi-cylinder engu-1. Bese uvula inkinobho yokushisa, uma ukukhanya kokuhlola kuvuliwe ngokujwayelekile, kubonisa ukuthi isistimu yepulaki yangaphambi kokushisa isebenza ngokujwayelekile. Ukwengeza, ukuklanywa kwepulaki yangaphambi kokushisa kudinga ukucabangela izinga lokushisa layo kanye nokuphikelela kwesimo sokushisa okuphezulu ukuze kuqinisekiswe ukuthi injini ye-diesel ingaqala ngokujwayelekile.
Umthelela omkhulu wokulimala kwepulaki yokushisisa imoto
Injini okunzima ukuyiqalisa : Umsebenzi oyinhloko wepulaki yokushisisa kuqala ukunikeza ukushisa okwengeziwe enjinini endaweni yezinga lokushisa eliphansi ukuyisiza iqale kahle. Uma ipulaki ye-preheat yonakele, injini ingase ingafinyeleli izinga lokushisa elivamile lokusebenza lapho iqala, okuholela ebunzimeni noma ekungakwazini ukuqalisa. .
ukwehla kokusebenza : ngisho noma injini ingakaqalisi, kungenzeka ukuthi izinga lokushisa liphansi kakhulu, okuholela ekushiseni okwanele kwengxube, ukuze ukusebenza kwenjini kwehle kakhulu.
ukwanda kokusetshenziswa kukaphethiloli : Ngenxa yokungashisi okwanele, ukusetshenziswa kukaphethiloli kwenjini kungase kunyuke, ngaleyo ndlela kukhuphule izindleko zokusebenza kwemoto.
ukungcola okungavamile : ukulimala kwepulaki lokushisisa kuqala kungase kuholele ezintweni eziyingozi ngokweqile esisi esikhishwa injini, njenge-carbon monoxide, ama-hydrocarbon, njll., ezongcolisa imvelo futhi ingase ithinte ukuphepha kokushayela. .
nciphisa impilo yenjini : ukusebenza isikhathi eside kulesi simo kuzodala umonakalo omkhulu enjinini, futhi kungase kuholele ngisho nasekulahlekeni ngokushesha kwenjini. .
Izimpawu eziqondile zokulimala kwangaphambili kwepulaki
Ubunzima bokuqalisa injini : esimweni sezulu esibandayo, ukulimala kwepulaki lokushisisa kuqala kungenza kube nzima ukudubula imoto.
amandla angaphansi : Ukulimala kwepulaki yokushisisa kungase kuphumele ekuncipheni kokusebenza kwenjini namandla ancishisiwe.
Ukwenyuka kokusetshenziswa kukaphethiloli : Ukwenyuka kokusetshenziswa kukaphethiloli kungase kubangele ukwehluleka kwenjini ukusebenza kahle.
ukukhishwa okungavamile : Ukulimala kwepulaki yokushisa ngaphambi kwesikhathi kungase kubangele izinto eziyingozi ngokweqile egesini yokukhipha umoya ekhishwa injini.
Ukukhanya kwesexwayiso sedeshibhodi kuvuliwe : Ezinye izimoto zifakwe uhlelo lokulawula ipulaki elishisa ngaphambi kwesikhathi elingase likhale i-alamu ngesibani esiyisixwayiso kudeshibhodi lapho isistimu ithola ukwehluleka kwepulaki lokushisa kusengaphambili.
