Umgomo wenzwa yokushisa yamanzi:

Inzwa yokushisa yamanzi iyingxenye ebalulekile yohlelo lokulawula izinsiza zemoto, olungaguqula izinga lokushisa libe yisiginali kagesi futhi lidlulise kwimodyuli yokulawula izimoto. Lapho izinga lokushisa lamanzi likhuphuka, amanzi anwebeka, futhi amandla athile okushisa amanzi akhudlwana, aphumela ekumelaneni okukhulu kwenzwa yokushisa yamanzi. Lokhu kuguqulwa kokumelana kutholwa yimodyuli yokulawula injini, elawula amapharamitha anjengomjovo wamafutha kanye nesikhathi sokulahla isikhathi. Ngasikhathi sinye, inzwa yokushisa kwamanzi ingathola futhi izinga lokushisa le-antifreeze, isiza umshayeli ukuthi aqonde isimo sokusebenza senjini kanye nesimo sokusebenza sohlelo lokupholisa.
Ngamafuphi, umthetho osebenzayo we-Water Temperiture Sensor ususelwa ekunwetsheni kwe-thermal kanye nezimpawu zokulwa kwamanzi. Lapho izinga lokushisa lamanzi likhuphuka, ukunwetshwa kwamanzi kubangela ukuba ukumelana kwezinzwa zokushisa kwamanzi kube nzima, futhi ushintsho lokumelana lutholwa yi-Injini Yokulawula injini, ngaleyo ndlela ilawule isimo esisebenzayo senjini.
Inzwa yezinga lamanzi esitsheni idlulisela izingeniso zamanzi ezizweyo kulawulo, futhi ikhompyutha kuMlawuli iqhathanisa ukuchezuka kwamanzi alinganiselwe ukuze kuqinisekiswe ukuthi isitsha sokuphambuka ngohlobo lwamanzi ngokuqiniseka. Ngemuva kokuthi inqubo yokuthathwa kwamanzi isiqediwe, ikhompyutha engxenyeni yokulawula izinga lokushisa ikhipha umyalo "ovulekile" ku-valve kagesi enikeza ukushisa okuphakathi, ngakho-ke uhlelo luqala ukushisa amanzi esitsheni. Ukusetha izinga lokushisa. Isilawuli sikhiphe umyalo wokuvala i-valve, sinqume umthombo wokushisa, futhi uhlelo lungene endaweni yokulondolozwa kokushisa. Esezinhlelweni zohlelo, ukuqinisekisa ukuthi uhlelo alufinyeleli ezingeni lamanzi aphephile, uMlawuli kagesi womthombo wokulawula awuvuli i-valve, ukuze ugweme ukulahleka kokushisa nezingozi.
Izinga lokushisa lamanzi kanye nenzwa yezinga lamanzi lakhiwa ingxenye yokulawulwa kwezinga lokushisa kanye nengxenye yokulawula amanzi, futhi ifaniswe nedivaysi yokuwabaza phambi kwe-valve kagesi kanye ne-heater ejikelezayo yokushisa. I-Car Water Temperiture Sensor ifakwe kwijantshi lamanzi le-Injini Block noma i-Cylinder Head futhi ixhumana ngqo ne-coolant ukukala izinga lokushisa elipholile lenjini. Inzwa yokushisa esetshenziswe ku-thermometer epholile yi-Thermistor (NTC) engemihle yokushisa i-Thermistor (NTC), ukumelana kwawo okunciphayo njengoba izinga lokushisa lincipha, ngentambo exhunyiwe kwi-ECU.
