Umsebenzi womlandeli we-elekthronikhi wezimoto
Ukupholisa injini nokusiza uhlelo lokupholisa umoya
Umsebenzi oyinhloko womshini we-elekthronikhi wezimoto ukupholisa injini nokusiza uhlelo lokupholisa umoya. Ngokukhethekile, luhlanganisa:
Ukupholisa injini: Ngokunciphisa izinga lokushisa lethangi lamanzi, kupholisa i-engine block kanye ne-transmission, kuvimbele ukushisa ngokweqile futhi kuqinisekise ukusebenza kahle kwenjini kanye nesikhathi sayo sokuphila.
Ukusiza uhlelo lokupholisa umoya: Lupholisa i-condenser yokupholisa umoya, lusheshise ukujikeleza kwe-coolant kwimodi yokupholisa futhi luthuthukise ukusebenza kahle kokupholisa; kwimodi yokushisa, lusiza ekuletheni umoya ofudumele ngaphakathi kwemoto.
Izimpawu eziyinhloko zokwehluleka kwefeni emotweni zifaka phakathi ukunyuka okungavamile kwezinga lokushisa lamanzi (i-alamu yokushisa okuphezulu kudeshibhodi), ukusebenza kwefeni okungavamile noma isivinini sefeni esingavamile, umsindo ongavamile (njengomsindo wokungqubuzana noma ukuchofoza) ngesikhathi sokusebenza, kanye nokwehla okukhulu ekusebenzeni kahle kokupholisa umoya opholile. Izimpawu ezithile zimi kanje:
Ukwanda okuqhubekayo kwezinga lokushisa lamanzi: Isikhombisi segeyiji yokushisa kwamanzi yedeshibhodi sidlula izinga elijwayelekile elingu-90°C noma isibani sesixwayiso sokushisa okuphezulu siyakhanya, ikakhulukazi lapho kungenzi lutho.
Ukusebenza kwefeni okungavamile: Ngokuvula indawo yenjini ukuze ihlolwe, ifeni ayijiki nhlobo, isebenza ngesivinini esiphansi kakhulu, noma isebenza ngesivinini esisodwa (njalo ngesivinini esiphezulu noma ngesivinini esiphansi).
Umsindo ongajwayelekile: Ifeni ikhipha imisindo yokungqubuzana okubukhali, ukuchofoza okuvamile, noma imisindo yokubhonga, okubonisa ukuguquka kwe-blade noma ukuguguleka kwamabhere.
Ukwehla okukhulu ekusebenzeni kahle kokupholisa umoya opholile: Ngemva kokuvula umoya opholile, izinga lokushisa lokukhipha umoya liyakhuphuka (ngaphezu kuka-10°C), kanti izinga lokushisa lamanzi nalo liyakhuphuka ngasikhathi sinye, ngenxa yokupholisa okunganele kwe-condenser.
Imiphumela: Amandla enjini ayancipha, ukusetshenziswa kukaphethiloli kuyanda, futhi ezimweni ezimbi kakhulu, kungase kube nephunga elishile noma iminonjana yokusha kwe-coil.
Izimbangela ezivamile zefeni kagesi engasebenzi emotweni zifaka phakathi ukuthintana kabi kweswishi yomoya opholile, ukwehluleka kwenjini noma amabheringi, izinga lokushisa lamanzi elanele, ama-fuse noma ama-relay alimele, kanye nezinkinga zokuxhuma izintambo.
Ukwehluleka kokulawula kanye nenzwa
Ukwehluleka kweswishi yokulawula izinga lokushisa noma inzwa: Ayikwazi ukubona izinga lokushisa lamanzi ngokunembile, okuholela ekutheni ifeni ingaqali emazingeni okushisa aphezulu (njengokwehluleka kwenzwa yokushisa kwamanzi noma ukuminyana kwe-thermostat).
Ukwehluleka kwe-ECU noma imodyuli yokulawula: Amaphutha ohlelo noma umonakalo wehadiwe kuyunithi yokulawula kagesi, okuvimba isignali yokuqala kwefeni (kudinga imishini yobungcweti yokuxilonga).
Izithiyo zemishini nezomzimba
Umonakalo wengxenye yefeni:
Ukuguga kwenjini noma ukuguguleka kwamabhere, okuholela ekunganele kwamandla.
Ama-blade avinjwe uthuli/izinto zakwamanye amazwe noma akhubazekile, avimbela ukujikeleza.
Ukuvaleka kwesistimu yokupholisa: Ukungcola okuqongelelekile kurediyetha kunciphisa ukusebenza kahle kokupholisa, okubangela ukuthi ifeni ime ngokungaqondile.
Ezinye izinto ezibalulekile
Ukwehluleka kwe-capacitor noma i-starter: Ukwehla kwamandla e-capacitor noma umonakalo we-starter, okuthinta ukusebenza kokuqala kwemoto.
Ukungaphumuli kwepompo yamanzi noma ukugcotshwa okunganele: Ukugeleza koketshezi olupholile okungajwayelekile (njenge-impeller ephukile) noma uwoyela onganele enjinini, okwandisa ukumelana nokungqubuzana.
Yebo, ifeni kagesi engasebenzi ingathinta kakhulu ukuphepha kokushayela.
Ifeni kagesi iyisici esibalulekile sohlelo lokupholisa injini. Umsebenzi wayo oyinhloko ukudonsa umoya obandayo nge-radiator nokusiza ekupholiseni i-coolant, ngaleyo ndlela igcine injini isebenza ngaphakathi kwezinga lokushisa elijwayelekile lokusebenza. Uma ifeni ihluleka, amandla okupholisa esistimu yokupholisa ehla kakhulu, futhi injini ithambekele kakhulu ekushiseni ngokweqile, okusongela ngqo ukuphepha kokushayela.
Imiphumela eyinhloko ifaka:
Ukushisa ngokweqile kwenjini, ukusebenza okunciphile
Ukungabikho kokusebenza kwefeni kuholela ekupholeni okubi, okubangela ukwenyuka okusheshayo kwezinga lokushisa lamanzi, futhi injini iziphatha "njengomkhuhlane", ayikwazi ukusebenza kahle, ngokuncipha kwamandla okukhipha kanye nokusetshenziswa kukaphethiloli okwandisiwe.
Ingozi ephezulu yomonakalo wemishini
Ukusebenza kwesikhathi eside emazingeni okushisa aphezulu kuzobangela ukuthi ukusebenza kokuthambisa uwoyela wenjini kwehle, kanye ne-piston, ibhulokhi yesilinda, nezinye izingxenye ezibalulekile zishise kakhulu futhi zande, okubangela kakhulu "isilinda esidonsayo", "ukubanjwa yibhere", "isilinda esiqhekekayo", ngisho nokwehluleka kwenjini.
Ingozi "yokubilisa" uketshezi olupholile, kanye nezingozi zokuphepha ezingaba khona.
Ukushisa okuphezulu kubangela ukuthi uketshezi olupholile lubile, okwandisa ingcindezi kakhulu, okungase kubangele ukuthi isembozo sethangi lamanzi sifafaze uketshezi noma ipayipi liqhume. Umusi oshisayo kanye noketshezi kungashisa abantu, okuyingozi kakhulu lapho kuhlolwa indawo yenjini.
Ukwehla okukhulu kokusebenza kahle kokupholisa umoya opholile. I-condenser yesistimu yokupholisa umoya ithembele nakubalandeli ekuqedeni ukushisa. Uma abalandeli beyeka ukujikeleza, umoya opholile ngeke ukwazi ukuqeda ukushisa kahle, okuholela ekunciphiseni okukhulu ekusebenzeni kahle kokupholisa futhi kuthinte induduzo yokushayela, ikakhulukazi ehlobo lapho ukukhathala ngenxa yokushayela kuba kubi kakhulu.
Ukwehluleka okuvamile kwenzeka ezimweni ezibucayi
Ngesikhathi sokuminyana kwezimoto, ukulinda ezibani ezibomvu, noma ukushayela ngesivinini esiphansi, umoya wemvelo awanele ukususa ukushisa, futhi indima yefeni ibaluleke kakhulu. Uma ifeni ingasebenzi ngalesi sikhathi, izinga lokushisa lenjini lizokhuphuka ngokushesha esikhathini esifushane, futhi kungenzeka kakhulu ukuthi kwenzeke ukwehluleka.
Nakuba esimweni sezulu esibandayo noma ukushayela ibanga elifushane, injini ishisa kancane futhi ingase ingabonakali ishisa okwesikhashana, lokhu akusho ukuthi ingashayelwa isikhathi eside. Uma izinga lokushisa lemvelo likhuphuka noma isikhathi sokushayela siqhubeka, ingozi izokhula kakhulu.
Ngakho-ke, uma uthola ukuthi ifeni kagesi ayijikelezi, kufanele umise imoto ngokushesha ukuze uyihlole futhi ungaqhubeki nokushayela. Izimbangela ezivamile zifaka:
Injini yefeni eyonakele noma endala
Amaphutha kuswishi yokulawula izinga lokushisa noma inzwa yokushisa kwamanzi
Ama-relay angasebenzi kahle noma ama-fuse aqhumile
Izinkinga ezifana nama-short circuits, ama-open circuits, njll.
Kunconywa ukuthi uxhumane nabasebenzi bokulungisa abangochwepheshe ukuze kutholakale ukuxilongwa nokufakwa esikhundleni ngokushesha okukhulu ukuze kugwenywe ukulahlekelwa okukhulu.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
