Isimiso sokusebenza sepulaki yenzwa yokushisa kwamanzi emoto
Isimiso sokusebenza senzwa yezinga lokushisa lamanzi ezimoto sisekelwe ezinguqukweni ku-thermistor. Emazingeni okushisa aphansi, inani lokumelana ne-thermistor likhulu; Ngokunyuka kwezinga lokushisa, inani lokumelana liyancipha kancane kancane. Iyunithi yokulawula ye-elekthronikhi (ECU) ibala izinga lokushisa langempela lesipholile ngokulinganisa ukuguqulwa kwamandla kagesi kokuphumayo kwenzwa. Lolu lwazi lwezinga lokushisa lusetshenziselwa ukulungisa inani lomjovo kaphethiloli, isikhathi sokuvutha kanye neminye imingcele ukuze kuqinisekiswe ukuthi injini ingakwazi ukugcina isimo esingcono kakhulu sokusebenza emazingeni okushisa ahlukene ukuze kuthuthukiswe ukonga kukaphethiloli nokusebenza kwamandla. .
Indima yenzwa yokushisa kwamanzi emoto emotweni ihlanganisa:
Ukulawula injini : Ngokolwazi lwezinga lokushisa olunikezwa inzwa yokushisa kwamanzi, i-ECU ilungisa inani lomjovo kaphethiloli, isikhathi sokuthungela kanye neminye imingcele ukuze kuqinisekiswe ukuthi injini ingakwazi ukugcina isimo esingcono kakhulu sokusebenza emazingeni okushisa ahlukene.
Ukulawulwa kwesistimu yokupholisa : uma izinga lokushisa lamanzi liphezulu kakhulu, i-ECU izolawula isiphephetha-moya ukuthi sisebenze ngesivinini esikhulu ukuze sithuthukise ukunqanyulwa kokushisa; Uma izinga lokushisa lamanzi liphansi kakhulu, yehlisa ukusebenza kwefeni ukushisisa injini ngokushesha okukhulu.
Isibonisi sedeshibhodi : Isignali esuka kunzwa yezinga lokushisa lamanzi idluliselwa kugeji yezinga lokushisa lamanzi kudeshibhodi, okuvumela umshayeli ukuba aqonde ngokunembile izinga lokushisa lenjini.
ukuxilonga iphutha : Uma inzwa yezinga lokushisa kwamanzi ihluleka, i-ECU irekhoda ikhodi yephutha efanelekile ukuze isize abasebenzi bokunakekela izingane bathole ngokushesha futhi baxazulule inkinga.
Izinhlobo zamaphutha ajwayelekile kanye nezimpawu zifaka:
Ukulimala kwenzwa : Endaweni enzima efana nezinga lokushisa eliphezulu nokudlidliza isikhathi eside, i-thermistor yenzwa ingase yonakaliswe, kubangele amasignali okukhiphayo anganembile noma kungabikho nhlobo isignali.
Iphutha lomugqa : Ulayini oxhuma inzwa yokushisa kwamanzi ku-ECU ingase ivuleke, isekethe isikhashana, noma ukuthintana okungalungile, kuthinte ukudluliswa kwesignali.
Ukungcola kwenzwa noma ukugqwala : Ukungcola nokungcola kwesipholile kungase kunamathele endaweni yenzwa, noma ukugqwala kwesipholile kungase kwehlise ukusebenza kwenzwa.
Izindlela zokuxazulula izinkinga zihlanganisa ukufunda ikhodi yephutha nokusebenzisa ukuxilongwa kwemoto ukuxhuma isixhumi esibonakalayo se-OBD semoto ukuze itholwe ukuze kutholwe ngokushesha futhi kuxazululwe inkinga.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko kule sayithi!
Sicela usishayele uma udinga imikhiqizo enjalo.
