Umgomo wokusebenza kwabalandeli bezimoto zikagesi
Ifeni kagesi yezimoto ilawula ngokuzenzakalelayo izinga lokushisa lenjini ngendlela ehlakaniphile yokulawula izinga lokushisa, iqinisekisa ukuthi isebenza ngaphakathi kwebanga lokusebenza elifanele.
Incazelo Yesimiso Sokusebenza
Ukuzwa Kwezinga Lokushisa Nokulawula Ukuqala/Ukumisa
Izingxenye eziyinhloko zokulawula zefeni kagesi yisilawuli sokushisa (noma inzwa yokushisa kwamanzi) kanye ne-ECU yenjini (i-Electronic Control Unit). Lapho izinga lokushisa le-coolant yenjini likhuphuka liye emkhawulweni ophezulu obekwe (ngokuvamile 92°C – 105°C), isilawuli sokushisa sivula ugesi bese ifeni iqala ukupholisa ngenkani. Uma izinga lokushisa lehla liye ebangeni eliphephile (njenge-88°C – 93°C), isilawuli sokushisa siyanqamula ugesi bese ifeni ima ngokuzenzakalelayo ukuze igweme ukupholisa ngokweqile okungathinta ukusebenza kahle kwenjini.
Indlela Yokulawula Isivinini Esinamazinga Amaningi
Iningi labalandeli be-elekthronikhi linezinketho zesivinini ezimbili noma ngisho namakhono esivinini esiningi:
Uma izinga lokushisa lamanzi lifinyelela cishe ku-90°C, ifeni isebenza ngesivinini esiphansi;
Uma izinga lokushisa likhuphuka ngaphezu kwama-95°C, lishintshela ekusebenzeni ngesivinini esikhulu ukuze kuthuthukiswe amandla okupholisa.
Lo mthetho uvame ukufezwa ngokushintsha kokushisa okubona izinga lokushisa lamanzi bese kuthunyelwa isignali kuyunithi yokulawula i-J293, bese isebenzisa umshayeli wesekethe ukushintsha umjikelezo womsebenzi noma isignali ye-PWM ukulawula isivinini.
Ukulawulwa Okuxhunyiwe Kwesistimu Yomoya Opholile
Ngisho noma izinga lokushisa lamanzi lingafikanga ezingeni eliphezulu, ukuqala i-air conditioner kuzobangela ukuthi ifeni isebenze. Ngenxa yokuthi i-air conditioner idinga ukuqeda ukushisa ukuze igcine umphumela wokupholisa, ikhompyutha ye-air conditioner (J301) izothumela isignali yokuqala ephoqelelwe kuyunithi yokulawula ifeni (J293), okwenza ifeni isebenze ngokubambisana. Lokhu kuqinisekisa ukusebenza kahle kwe-air conditioner ngenkathi kuvimbela umthwalo owengeziwe enjinini ukuthi ungabangeli ukushisa ngokweqile.
Ukulibaziseka Kokupholisa Ngemva Kokuvala Injini
Amanye amamodeli ezimoto anesici "sokupholisa ngokubambezeleka": Ngemva kokuba injini icimile, uma izinga lokushisa le-coolant lihlala lingaphezu kwenani elithile (njengo-117°C), ifeni izoqhubeka isebenza imizuzu embalwa kuze kube yilapho izinga lokushisa lehla liye ezingeni eliphephile ukuvimbela "ukuqongelela kokushisa" kanye nokunye ukwehluleka.
Ukuvikelwa Kwamaphutha Nokuqapha Uhlelo
Izinhlelo zanamuhla zabalandeli be-elekthronikhi zihlonyiswe ngezindlela zokuvikela eziphelele, okuhlanganisa ukuqapha kwangempela kwamandla emoto, i-voltage, kanye nesivinini. Uma kutholwa noma yiziphi izinkinga ezifana ne-overvoltage, i-overcurrent, i-short circuit, noma i-motor jamming, uhlelo lokulawula luzosusa ukuvikelwa kokuvala ugesi ukuze kuvinjelwe umonakalo ohlelweni lonke lokupholisa.
Ukuqhathaniswa Nezinye Izinhlobo Zabalandeli
I-Electronic Fan vs I-Silicone Oil Clutch Fan
Ifeni kagesi ilawulwa ngokunembile yi-ECU, isabela ngokushesha futhi isebenza kahle kakhulu, ifanele izinhlelo zokuphatha ukushisa ezihlakaniphile zesimanje; kuyilapho ifeni kawoyela we-silicone iqhutshwa yimpahla ebonakalayo yokwandiswa kokushisa kawoyela we-silicone, inesakhiwo esilula kodwa ukunemba kokulawula okuphansi.
Umlandeli We-elekthronikhi vs Umlandeli Wemishini Wendabuko
Amafeni endabuko omshini aqhutshwa ngqo yibhande lenjini futhi asebenza njalo; asebenzisa amandla amaningi; kuyilapho ifeni kagesi iqala futhi ima njengoba kudingeka, okunciphisa kakhulu ukulahleka kwamandla futhi kuthuthukise ukonga kukaphethiloli.
Ukwahlulela ukuthi ifeni kagesi yezimoto isebenza kahle yini kungenziwa ngezici eziningi njengokubuka isimo sokusebenza, ukulalela umsindo, ukubona izinguquko zokushisa, kanye nokuhlola izingxenye ezihlobene.
Indlela Yokubuka Eqondayo
Hlola ukuthi ifeni iyajikeleza yini
Qala injini bese ulinda izinga lokushisa lamanzi likhuphuke ngaphezu kuka-80°C (cishe imizuzu emi-5-10), bese uvula i-hood bese ubheka ukuthi ifeni ye-radiator iqala ngokuzenzakalelayo yini. Ngokuvamile, lapho izinga lokushisa lamanzi lifinyelela ku-90–98°C, ifeni kufanele iqale ngesivinini esiphansi; uma izinga lokushisa liqhubeka nokwenyuka (njengangaphezu kuka-102°C), lizoshintshela kwimodi yesivinini esiphezulu.
Hlola Umsebenzi Oxhumene Nomoya Opholile
Vula imodi yokupholisa umoya opholile, noma ngabe izinga lokushisa lamanzi aliphezulu, ifeni kufanele futhi iqale ukusiza i-condenser ekupholiseni. Uma ifeni ingaphenduli ngemva kokuvula umoya opholile, kungase kube nephutha kusekethe yokulawula noma i-relay.
Ukwahlulela Okuwusizo Kokuzwa Nokuthinta
Lalela umsindo osebenzayo
Ifeni isebenza ngomsindo ofanayo "ojikelezayo". Uma kukhona umsindo "obambekayo" ongavamile noma umsindo wokungqubuzana obukhali, kungase kube ngenxa yokuguquguquka kwe-blade, ukuguguleka kwamabhere, noma ukwehluleka kwenjini.
Zizwe Umthamo Wokuhamba Komoya Ngaphansi kwezimo eziphephile, uma usondeza isandla sakho ngemuva kwefeni (kodwa ungazithinti izindwani), kufanele ukwazi ukuzwa kahle ukuhamba komoya okunamandla. Uma kungekho moya noma umoya ubuthakathaka, kungase kubonise amandla anganele enjini noma izindwani zezindwani ezinamathele.
Ukuqapha izinga lokushisa kanye nezinsimbi
Qaphela izinga lokushisa lamanzi: Uma izinga lokushisa lamanzi lihlala liphezulu (isikhombisi siseduze nendawo ebomvu) futhi ifeni ingaqali, kusho ukuthi ifeni ayisebenzi njengoba kudingeka.
Uma ifeni iqhubeka nokusebenza imizuzu embalwa ngemva kokuba injini icishiwe, kuwumsebenzi ojwayelekile wokuphola ngokubambezeleka; kodwa uma ingayeki ukujikeleza isikhathi eside, kungaba iphutha kuswishi yokulawula izinga lokushisa noma imojuli yokulawula.
Ukuhlolwa kwezingxenye ezibalulekile
Hlola ama-fuse nama-relay
Thola ibhokisi le-fuse engxenyeni yenjini, qinisekisa ukuthi i-fuse ehambisana nefeni iqhumile yini, nokuthi i-relay isebenza kahle yini. Ungahlola ukusebenza kwe-relay ngokuyishintsha.
Hlola injini kanye nezintambo
Nqamula ipulaki yefeni bese uxhuma ngqo umthombo wamandla we-12V. Ifeni kufanele ikwazi ukujikeleza ngokujwayelekile futhi akufanele kube nomsindo ongajwayelekile. Ngaphandle kwalokho, injini iyonakala.
Sebenzisa i-multimeter ukukala ukumelana kwenjini. Uma ukumelana kungavamile (kuphezulu kakhulu noma kungapheli), kubonisa iphutha lokugoqa kwangaphakathi.
Ukuxazulula izinkinga zezinzwa zokulawula izinga lokushisa kanye namaswishi
Ukwehluleka kwenzwa yokushisa kwamanzi noma iswishi yokushisa kuzokwenza ukuthi ifeni yehluleke ukuthola isignali yokuqala. Ungafunda umfudlana wedatha yokushisa kwamanzi usebenzisa ithuluzi lokuxilonga noma uhlole izinga lokushisa lokuqhuba kweswishi yokulawula ukushisa emanzini ashisayo (ngokuvamile u-93–98°C uyaqhuba).
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
