Isimiso senzwa yezinga lokushisa kwamanzi:

Inzwa yokushisa kwamanzi iyingxenye ebalulekile yesistimu yokulawula injini yemoto, engaguqula izinga lokushisa libe isignali kagesi futhi idlulisele kumojula yokulawula injini yemoto. Lapho izinga lokushisa lamanzi likhuphuka, amanzi ayanda, futhi umthamo othile wokushisa wamanzi uba mkhulu, okuholela ekuphikiseni okukhulu kwenzwa yokushisa kwamanzi. Lokhu kushintsha kokumelana nakho kutholwa yimojula yokulawula injini, elawula imingcele efana nomjovo kaphethiloli kanye nesikhathi sokubasa. Ngesikhathi esifanayo, inzwa yokushisa kwamanzi ingakwazi futhi ukubona izinga lokushisa le-antifreeze, isiza umshayeli ukuba aqonde isimo sokusebenza kwenjini kanye nesimo sokusebenza sesistimu yokupholisa.
Ngamafuphi, isimiso sokusebenza senzwa yokushisa kwamanzi sisekelwe ekwandiseni okushisayo nezici zokufinyela ezibandayo zamanzi. Lapho izinga lokushisa lamanzi likhuphuka, ukwanda kwamanzi kubangela ukumelana kwenzwa yokushisa kwamanzi kube kukhudlwana, futhi ukuguqulwa kokumelana kutholwa yimodyuli yokulawula injini, ngaleyo ndlela ilawula isimo sokusebenza senjini.
Inzwa yezinga lamanzi esitsheni idlulisela isignali yezinga lamanzi azwakele kusilawuli, futhi ikhompuyutha kusilawuli iqhathanisa isignali yezinga lamanzi elilinganisiwe nesignali emisiwe ukuze kutholwe ukuchezuka, bese ikhipha imiyalelo "yokuvula" kanye "nokuvala" ku-valve kagesi yokuphakelwa kwamanzi ngokwesimo sokuchezuka ukuze kuqinisekiswe ukuthi isiqukathi sifinyelela ezingeni elimisiwe lamanzi. Ngemuva kokuthi inqubo yokuthatha amanzi isiqediwe, ikhompyutha engxenyeni yokulawula izinga lokushisa ikhipha umyalo "ovulekile" ku-valve kagesi enikeza indawo yokushisa, ngakho uhlelo luqala ukushisa amanzi esitsheni. Ukusetha izinga lokushisa. Isilawuli sikhiphe umyalo wokuvala i-valve, kunqanyulwe umthombo wokushisa, futhi isistimu ingene esimweni sokugcina ukushisa. Enkambweni yokuhlela, ukuqinisekisa ukuthi uhlelo alufinyeleli ezingeni lamanzi aphephile, umlawuli kagesi womthombo wokushisa olawulayo awuvuli i-valve, ukuze ugweme ukulahlekelwa ukushisa kanye nezingozi.
Inzwa yezinga lokushisa lamanzi neleveli yamanzi yakhiwe ingxenye yesilawuli sezinga lokushisa kanye nengxenye yokulawula izinga lamanzi, futhi ifaniswe nedivayisi yokucindezela phambi kwe-valve kagesi kanye ne-rotary muffler heater yokufudumala. Inzwa yezinga lokushisa lamanzi emoto ifakwe ejazini lamanzi lebhulokhi yenjini noma ekhanda lesilinda futhi ithintana ngqo nesipholile ukuze kukale izinga lokushisa elipholile lenjini. Inzwa yezinga lokushisa esetshenziswa kuthemometha epholile i-coefficient thermistor (NTC) engemihle, ukumelana kwayo kuncipha njengoba izinga lokushisa likhuphuka, ngentambo exhunywe ku-ECU.
