Izimpawu zokungasebenzi kahle kwepulaki yesenzwa yokushisa kwamanzi emotweni
Uma ipulaki yokuzwa izinga lokushisa kwamanzi (inzwa yokushisa kwamanzi) yemoto ingasebenzi kahle, izimpawu eziyinhloko zifaka phakathi igeyiji yokushisa kwamanzi engajwayelekile, ubunzima bokuqala imoto ebandayo, ukwanda okukhulu kokusetshenziswa kukaphethiloli, isivinini esingazinzile sokungenzi lutho, kanye nokusheshisa okubuthakathaka, njll. Okulandelayo yizimpawu nezimbangela ezithile:
Isilinganiso sokushisa kwamanzi "asisebenzi kahle" noma sigxuma ngokungahleliwe
Ipulaki yesensa yokushisa kwamanzi eyonakele ingabangela ukubonakaliswa okungavamile kwesilinganiso sokushisa kwamanzi kudeshibhodi. Izimo ezivamile zifaka:
Isikhombisi sinamathele endaweni ephansi noma ephezulu kakhulu: isikhombisi asihambi ngemva kokuqala kokubanda, noma sikhomba ngqo endaweni yomugqa obomvu oshisa kakhulu (izinga lokushisa langempela lamanzi lingase libe elijwayelekile).
Isikhombisi siyashintshashintsha phezulu naphansi: isignali yokushisa kwamanzi ayizinzile, lapho isikhombisi sishintshashintsha kakhulu phakathi kuka-80℃ no-100℃, okungase kubangele ngephutha i-alamu yokushisa okuphezulu.
Kunzima ukuqala imoto ebandayo
Uma iqala ukubanda, injini idinga ukuvuthelwa ngokuphindaphindiwe ukuze iqale, futhi ngisho nokhiye udinga ukujikwa izikhathi eziningana.
Ipulaki yesensa ibike ngephutha "ngesignali yemoto efudumele", okwenza i-ECU (ikhompyutha esebhodini) yehlise ukujova uphethiloli futhi ingxube ibe mncane kakhulu ukuba ingavutha.
Ukuqala okushisayo nakho kungathinteka, okuholela ekukhuphukeni okungazelelwe kwesivinini senjini noma intuthu emnyama ephuma epayipini lokukhipha umoya.
Ukwanda okungazelelwe kokusetshenziswa kukaphethiloli
Ithangi likaphethiloli lingagijima amakhilomitha angaba yi-100 ngaphansi kunokuvamile.
Ipulaki yesensa ithumela njalo "isignali yokushisa okuphansi", futhi i-ECU ifaka uphethiloli owedlulele kwimodi yemoto ebandayo, okuholela ekushiseni kukaphethiloli okungaphelele.
Inzwa yezinga lamanzi ngaphakathi kwesitsha idlulisela isignali yezinga lamanzi elizwayo kumlawuli. Ikhompyutha engaphakathi kwesilawuli iqhathanisa isignali yezinga lamanzi elilinganisiwe nesignali esethiwe ukuze inqume ukuphambuka. Bese, ngokusekelwe ohlotsheni lokuphambuka, ikhipha imiyalelo "yokuvula" kanye "nokuvala" kuvalvu kagesi yokuphakelwa kwamanzi ukuqinisekisa ukuthi isitsha sifinyelela ezingeni lamanzi elibekiwe. Ngemva kokuba uhlelo lokungena kwamanzi seluqediwe, ikhompyutha engxenyeni yokulawula izinga lokushisa ikhipha umyalo "wokuvula" kuvalvu kagesi enikeza indawo yokushisa, ngaleyo ndlela uhlelo luqala ukushisa amanzi esitsheni. Lapho izinga lokushisa elibekiwe selifinyelelwe. Njengoba nje isilawuli sikhipha umyalo wokuvala ivalvu futhi sinqume umthombo wokushisa, uhlelo lungena esimweni sokulondolozwa kokushisa. Ngesikhathi senqubo yokuhlela, kwaqinisekiswa ukuthi ivalvu elawula ugesi elawula umthombo wokushisa ngeke ivuleke kuze kube yilapho izinga lamanzi aphephile selifinyelelwe, ngaleyo ndlela kugwenywe ukulahlekelwa ukushisa kanye nokuvela kwezingozi.
Ipulaki yesensa yokushisa kwamanzi yezimoto (ngokuvamile ebhekisela esensa yokushisa kwamanzi) iyisici esibalulekile ohlelweni lokupholisa injini. Umsebenzi wayo oyinhloko ukuqapha izinga lokushisa le-coolant nokunikeza izimpawu zokushisa zesikhathi sangempela kuyunithi yokulawula injini (ECU).
Ipulaki yesenzwa yokushisa kwamanzi ishintsha inani lokumelana kwe-thermistor yangaphakathi ye-NTC ngezinguquko zokushisa, ngaleyo ndlela iguqula izinga lokushisa elingokoqobo libe isignali kagesi (njengesignali ye-voltage). Ngemva kokuthola lesi signali, i-ECU iyisebenzisela ukulungisa ngokuguquguqukayo izimo zokusebenza kwenjini.
Imisebenzi ethile ihlanganisa:
I-Youdaoplaceholder0 Ivolumu efanele yokufaka uphethiloli : Khulisa ivolumu yokufaka uphethiloli ye-ECU emazingeni okushisa aphansi ukuze uthuthukise ukusebenza kokuqala okubandayo, futhi unciphise ivolumu yokufaka uphethiloli lapho izinga lokushisa libuyela kokujwayelekile ukuze uthuthukise isilinganiso somoya-uphethiloli.
I-Youdaoplaceholder0 Lungisa i-engela yokushisa kwangaphambili : Khulisa i-engela yokushisa kwangaphambili emazingeni okushisa aphansi ukuze uthuthukise ukusebenza kahle kokushisa, bese uyibambezela emazingeni okushisa aphezulu ukuze uvimbele ukubola.
Ukuqina kwesivinini sokungavimbi kwe-Youdaoplaceholder0: Uma uqala emazingeni okushisa aphansi, i-ECU ikhulisa isivinini ngevalvu yokulawula isivinini sokungavimbi ukuze isheshise ukufudumala nokugcina ukusebenza kahle.
Isilinganiso sokushisa kwamanzi se-Youdaoplaceholder0 Drive : sinikeza isignali yokwenza i-gauge yokushisa kwamanzi kuphaneli yezinsimbi ibonise izinga lokushisa lokusebenza kwenjini, okwenza kube lula ukuqapha komshayeli.
I-Youdaoplaceholder0 Ukulawulwa kokukhishwa kwegesi okuhlanganisiwe : Bamba iqhaza ekulawulweni kwezinhlelo ze-EGR, njll., futhi uthuthukise isilinganiso sokujikeleza kwegesi yokukhipha ukuze unciphise ukukhishwa kwegesi.
Ngaphezu kwalokho, ipulaki yesenzwa yokushisa kwamanzi ithinta ukuqala nokuma kwefeni yokupholisa kanye nokusebenza kwe-thermostat, iqinisekisa ukuthi injini ifinyelela ngokushesha futhi igcine izinga lokushisa lokusebenza elifanele (ngokuvamile 80°C - 90°C), ngaleyo ndlela inciphise ukuguguleka, ithuthukise ukusebenza kwamandla kanye nokonga.
