Umgaqo wenzwa yobushushu bamanzi:

Inzwa yobushushu bamanzi yinxalenye ebalulekileyo yenkqubo yokulawula injini yemoto, enokuguqula iqondo lokushisa libe ngumqondiso wombane kwaye idlulisele kwimodyuli yokulawula injini yemoto. Xa ubushushu bamanzi bukhuphuka, amanzi ayanda, kwaye amandla athile obushushu bamanzi makhulu, okukhokelela ekuchaseni okukhulu kwenzwa yobushushu bamanzi. Olu tshintsho lokumelana lufunyenwe yimodyuli yokulawula injini, elawula iiparamitha ezifana nenaliti yamafutha kunye nexesha lokutshisa. Kwangaxeshanye, inzwa yobushushu bamanzi inokuphinda ibone ubushushu be-antifreeze, inceda umqhubi ukuba aqonde imeko yokusebenza kwe-injini kunye nobume bokusebenza kwenkqubo yokupholisa.
Ngamafutshane, umgaqo wokusebenza kwenzwa yokushisa kwamanzi isekelwe kukwandiswa kwe-thermal kunye neempawu ezibandayo ezibandayo zamanzi. Xa ubushushu bamanzi buphakama, ukwandiswa kwamanzi kubangela ukuchasana kwenzwa yokushisa kwamanzi ukuba kube mkhulu, kwaye utshintsho lokumelana lubonwa yimodyuli yokulawula injini, ngaloo ndlela ilawula imeko yokusebenza ye-injini.
Isivamvo somgangatho wamanzi kwisikhongozeli sidlulisela umqondiso wenqanaba lamanzi kumlawuli, kwaye ikhompyuter kwisilawuli ithelekisa umqondiso womgangatho wamanzi olinganisiweyo kunye nomqondiso obekiweyo wokufumana ukutenxa, kwaye emva koko ikhuphe imiyalelo "evulekileyo" kwaye "ivale" kwivalve yombane yonikezelo lwamanzi ngokobume bokutenxa ukuqinisekisa ukuba isikhongozeli sifikelela kwinqanaba elimiselweyo lamanzi. Emva kokuba inkqubo yokungena kwamanzi igqityiwe, ikhompyutha kwinxalenye yokulawula ubushushu ikhupha umyalelo "ovulekileyo" kwivalve yombane enika indawo yokufudumala, ngoko ke inkqubo iqala ukutshisa amanzi kwisitya. Ukuseta ubushushu. Umlawuli ukhuphe umyalelo wokuvala ivalve, unqumle umthombo wobushushu, kwaye inkqubo yangena kwisimo sokugcina ubushushu. Kwinkqubo yokucwangcisa, ukuqinisekisa ukuba inkqubo ayifikeleli kwinqanaba lamanzi akhuselekileyo, umlawuli wombane wolawulo lokushisa umthombo awuvuli i-valve, ukwenzela ukuba ugweme ukulahleka kobushushu kunye neengozi.
Ubushushu bamanzi kunye nomgangatho wamanzi we-sensor yamanzi yenziwe inxalenye yokulawula ubushushu kunye nenxalenye yokulawula umgangatho wamanzi, kwaye ihambelana nesixhobo sokunciphisa phambi kwe-valve yombane kunye ne-rotary muffler heater yokufudumala. Isivamvo sobushushu bamanzi emoto sifakwe kwibhatyi yamanzi yebloko yenjini okanye kwintloko yesilinda kwaye sidibana ngokuthe ngqo nesisipholisi ukulinganisa ubushushu bokupholisa be-injini. I-sensor yeqondo lokushisa elisetyenziswe kwi-thermometer epholileyo yi-coefficient ye-thermistor engalunganga (NTC), ukunyanzeliswa kwayo kuncipha njengoko iqondo lokushisa linyuka, kunye nocingo oluxhunyiwe kwi-ECU.
