Inzwa Yokushisa Kwamanzi Enjini: Umqaphi Wokushisa Kwenjini Nokutholwa Kwephutha
Ohlelweni oluqondile lokusebenza kwenjini yemoto, inzwa yokushisa kwamanzi isebenza njengomqaphi othule wokushisa, iqapha njalo izinga lokushisa kwe-coolant yenjini futhi ivikele ukusebenza okuzinzile kwenjini. Nakuba incane ngobukhulu, idlala indima engenakuphindwa ekulawulweni kokusebenza kwenjini kanye nokuqinisekisa ukonga uphethiloli. Uma inzwa yokushisa kwamanzi ingasebenzi kahle, izoletha izingozi eziningi ezingaba khona ekusebenzeni kwemoto, okudinga umnikazi ukuthi ayibone futhi ayiphathe ngesikhathi.
Umsebenzi Oyinhloko Wenzwa Yokushisa Kwamanzi Enjini
Inzwa yokushisa kwamanzi, eyaziwa nangokuthi inzwa yokushisa kwamanzi, iguqula kakhulu izinguquko zokushisa kwe-coolant zibe izimpawu zikagesi ngezingxenye zayo zangaphakathi ze-thermistor bese izithumela kuyunithi yokulawula imoto ukuze kufezwe ukulawulwa okunembile kwenjini. Imisebenzi yayo eyinhloko ibonakala kakhulu kulezi zici ezilandelayo:
Okokuqala, iqapha izinga lokushisa le-coolant ngesikhathi sangempela ukuqinisekisa izinga lokushisa lokusebenza elizinzile lenjini. Kuphela uma injini isebenza ngaphakathi kwebanga lokushisa elifanele lapho ingasebenza khona kahle. Inzwa yokushisa kwamanzi ingakwazi ukubamba izinguquko zokushisa ze-coolant ngesikhathi sangempela. Ngesikhathi sokuqala okubandayo, izodlulisela isignali yokushisa okuphansi kuyunithi yokulawula, futhi iyunithi yokulawula izolungisa isivinini sefeni futhi inyuse isivinini sokungenzi lutho ukuze isheshise inqubo yokufudumala kwenjini, ivumele injini ukuthi ingene esimweni sokusebenza esifanele ngokushesha okukhulu; lapho izinga lokushisa lenjini liphezulu kakhulu, izobangela ifeni ukuthi isebenze ngesivinini esikhulu ukuze ipholise injini ngokushesha, ivimbele ukuguguleka okusheshayo ngisho nomonakalo wezingxenye ngenxa yokushisa ngokweqile.
Okwesibili, ilungisa ukujova uphethiloli kanye nesikhathi sokusha, ithuthukisa ukonga uphethiloli kanye nokusebenza kwamandla. Isignali yokushisa edluliselwa yinzwa yokushisa kwamanzi iyinkomba ebalulekile ohlelweni lokujova uphethiloli kanye nohlelo lokusha. Ezindaweni ezibandayo, injini idinga ingxube ecebile ukuze iqale kahle. Inzwa yokushisa kwamanzi izophendula isignali yokushisa okuphansi kuyunithi yokulawula, kanti iyunithi yokulawula izokwandisa ivolumu yokujova uphethiloli futhi ikhulise ngokufanele i-engeli yokusha ukuze kuqinisekiswe ukuthi injini iqala kahle; lapho injini ifinyelela izinga lokushisa elijwayelekile lokusebenza, izokhuthaza iyunithi yokulawula ukuthi ilungise ivolumu yokujova uphethiloli kanye nesikhathi sokusha, okuvumela ukushiswa kukaphethiloli okuphelele, okungagcini nje ngokuthuthukisa ukonga uphethiloli kodwa futhi okuqinisekisa ukuphuma kwamandla enjini.
Okokugcina, inikeza idatha yesilinganiso sokushisa kwamanzi, okuvumela umnikazi ukuthi aqaphe isimo senjini ngesikhathi sangempela. Inzwa yokushisa kwamanzi izodlulisela isignali yokushisa eqashwe ngesikhathi sangempela kusilinganiso sokushisa kwamanzi kudeshibhodi yemoto. Ngokubheka ukufundwa kwesilinganiso sokushisa kwamanzi, umnikazi angaqonda ngokwemvelo izinga lokushisa lokusebenza kwenjini. Uma kwenzeka ukungahambi kahle ekushiseni kwamanzi, umnikazi angathatha izinyathelo ngokushesha futhi amise imoto ukuze ihlolwe ukuze agweme amaphutha amakhulu abangelwa ukushisa ngokweqile noma ukupholisa injini.
Amaphutha Avamile Nokuxazulula Izinkinga Zenzwa Yokushisa Kwamanzi Enjini
Njengengxenye ye-elekthronikhi, inzwa yokushisa kwamanzi ingase ingasebenzi kahle ngenxa yokuguga, amaphutha esekhethini, noma ukungcola ngesikhathi sokusetshenziswa isikhathi eside, ngaleyo ndlela kuthinte ukusebenza okuvamile kwemoto. Ukubonakaliswa kwamaphutha okuvamile kanye nezindlela zokuxazulula izinkinga yilezi ezilandelayo:
Ukungajwayelekile kwesilinganiso sokushisa kwamanzi sedeshibhodi Lokhu kuwukubonakaliswa okusobala kakhulu kokwehluleka kwenzwa yokushisa kwamanzi. Lapho isekethe yangaphakathi yenzwa yokushisa kwamanzi inqanyuliwe, ayikwazi ukudlulisa isignali yokushisa kuyunithi yokulawula, futhi inkomba yokulinganisa izinga lokushisa kwamanzi izohlala isendaweni "0", noma ngabe injini ifinyelela izinga lokushisa elijwayelekile, izohlala ingashintshi; kuyilapho lapho inzwa ifinyeziwe, ukumelana kwehla kakhulu, futhi iyunithi yokulawula izokwahlulela ngephutha injini njengeshiswe kakhulu, inkomba yokulinganisa izinga lokushisa kwamanzi izofika ngqo endaweni ebomvu ephezulu kakhulu, futhi ngesikhathi esifanayo, isibani sesixwayiso sokushisa kwamanzi sizovulwa. Kulesi simo, umnikazi angaqala ahlole ukuthi uxhumano lwezintambo lwenzwa yokushisa kwamanzi lukhululekile noma lu-oxidized. Uma izintambo zivamile, kungenzeka ukuthi inzwa yokushisa kwamanzi yonakele, futhi kudingeka enye esikhundleni sayo.
Ubunzima ekuqaliseni okubandayo kanye nokungahlaliseki kahle Uma uqala injini ebandayo, uma inzwa yokushisa kwamanzi inephutha futhi iphendula isignali yokushisa yokufudumeza, iyunithi yokulawula izohlinzeka ngengxube encane ngokwesimo sokufudumeza, okwenza injini ibe nobunzima bokuqala ngenxa yengxube encane. Ngaphezu kwalokho, inzwa yokushisa kwamanzi enephutha izophinde ibangele ukungahlaliseki kahle, lapho injini ebandayo ibika kabi izinga lokushisa eliphezulu, isivinini sokungahlaliseki sizokwehla kakhulu, futhi injini izozamazama ngokuphawulekayo; Uma imoto ibika kabi izinga lokushisa eliphansi ngesikhathi sokufudumeza, isivinini sokungahlaliseki sizokhuphuka futhi umsindo uzokwanda. Uma kwenzeka iphutha elinjalo, umnikazi angasebenzisa i-multimeter ukuthola ushintsho lokumelana kwenzwa yokushisa kwamanzi. Ngokufudumeza inzwa nge-hair dryer kagesi, uma inani lokumelana lingashintshi, kubonisa ukuthi inzwa yonakele futhi idinga ukushintshwa ngesikhathi.
Ukwanda kokusetshenziswa kukaphethiloli kanye nokwehla kwamandla kubangelwa ukwehluleka kwenzwa yokushisa kwamanzi. Kungaholela ekuphambukeni ekulawulweni kweyunithi yokulawula kwevolumu yokujova uphethiloli. Isibonelo, lapho inzwa ibika isignali yokushisa ephansi, iyunithi yokulawula izoqhubeka nokukhulisa ivolumu yokujova uphethiloli, okuholela ekuchithekeni kukaphethiloli kanye nokwanda okukhulu kokusetshenziswa kukaphethiloli; ngesikhathi esifanayo, isignali engalungile izothinta nesikhathi sokusha, okubangela ukungasebenzi kahle kwamandla enjini kanye nokusheshisa okubuthakathaka. Uma umnikazi eqaphela ukuthi ukusetshenziswa kukaphethiloli kukhuphuke ngokuzumayo ngendlela engaqondakali futhi amandla ehlile muva nje, ngemuva kokukhipha izici ezifana nomfutho wamathayi kanye nemikhuba yokushayela, kufanele acabangele ukuthi kungenzeka ukuthi inzwa yokushisa kwamanzi ihluleke futhi ayihlole ngokushesha esitolo sokulungisa sochwepheshe.
Ipulaki yesenzwa yokushisa kwamanzi yemoto iyisici esibalulekile ekusebenzeni okuvamile kwenjini. Ukusebenza kwayo okunembile kuqinisekisa ukusebenza okuzinzile kwenjini ngaphansi kwezimo zokusebenza ezahlukahlukene. Uma usebenzisa imoto nsuku zonke, abanikazi bezimoto kufanele banake kakhulu ukufundwa kwesilinganiso sokushisa kwamanzi, isimo sokuqala, kanye nezinguquko ekusetshenzisweni kukaphethiloli. Uma kutholakala noma yikuphi ukukhubazeka, kufanele bahlole ngokushesha ukuthi ipulaki yesenzwa yokushisa kwamanzi ayisebenzi kahle yini. Ukunakekelwa njalo kobungcweti kwemoto kungandisa ngempumelelo impilo yepulaki yesenzwa yokushisa kwamanzi, kugcine injini isesimweni esihle sokusebenza futhi inikeze isiqinisekiso esithembekile sokuphepha kokushayela kanye nesipiliyoni sokushayela.
