Umsebenzi wefeni ye-elektroniki yeemoto
Ifeni ye-elektroniki yeemoto yinxalenye ebalulekileyo yenkqubo yokupholisa yesithuthi, esebenza ngokuyintloko ukunceda ukugcina ubushushu obufanelekileyo bokusebenza kwenjini kunye nezinto ezinxulumene nayo, ukuqinisekisa ukuba imoto isebenza ngokufanelekileyo nangokukhuselekileyo.
Umsebenzi ophambili wefeni ye-elektroniki kukukhupha ubushushu. Oku kwenza ngokunyanzela umoya ukuba udlule phezu kweradiator (itanki yamanzi) ukuze kuphole i-coolant yenjini eshushu, nto leyo ethintela injini ukuba ingatshisi kakhulu. Idla ngokulawulwa yi-sensor yobushushu bamanzi okanye iswitshi yokulawula ubushushu. Xa ubushushu be-coolant bufikelela kumda omiselweyo (ofana ne-90°C okanye i-95°C), iqala ngokuzenzekelayo, ime xa ubushushu buhla, ifezekisa ukonga amandla kunye nolawulo olufanelekileyo.
Ukongeza, ifeni ye-elektroniki ixhasa ukusebenza kwenkqubo yokupholisa umoya. Kwiindlela zokupholisa okanye zokufudumeza, iqhuba umoya ukuba udlule kwi-condenser yokupholisa umoya okanye kwi-evaporator ukuphucula ukusebenza kakuhle kokupholisa okanye ukusasaza umoya oshushu, ngaloo ndlela ilawula ubushushu bangaphakathi.
Ulawulo olukrelekrele lwefeni ye-elektroniki luzisa iingenelo ezininzi, kubandakanya ukuphucula ukusetyenziswa kwamandla ngokulungelelanisa isantya (njengeendlela zesantya esiphezulu nesiphantsi), ukunciphisa umthwalo wenjini, kunye nokubuyisela umoya onganeleyo wendalo ngesantya esiphantsi okanye idling, ukuqinisekisa isiphumo sokupholisa.
Ukusombulula ingxaki yokusilela kwefeni ye-elektroniki engajikeleziyo kufuna indlela yenyathelo nenyathelo: Okokuqala, jonga ukuba ubushushu bamanzi bungaphakathi koluhlu oluqhelekileyo (ubushushu obuqhelekileyo bokuqalisa bumalunga nama-90-95°C). Emva koko, vavanya iifusi, iirelayini, iswitshi yokulawula ubushushu, kunye nemoto ngokulandelelana. Nantsi inkqubo yokusombulula iingxaki ngokucwangcisiweyo:
Uhlolo olusisiseko (umsebenzi ophambili)
Ukuchonga ubushushu bamanzi: Qalisa injini ukuze ifikelele kubushushu obuqhelekileyo bokusebenza (malunga nemizuzu eli-10), jonga igeyiji yobushushu bamanzi kwideshibhodi. Ukuba ubushushu bamanzi bungaphantsi kwama-90°C, ifeni engajikeleziyo yinto eqhelekileyo; ukuba ubushushu bamanzi bungaphakathi koluhlu oluqhelekileyo kodwa bungajikelezi, kufuneka uphando olongezelelweyo.
Ukuhlolwa kwefuse: Vula ibhokisi yefuse yegumbi lenjini, fumana ifuse yefeni (jonga incwadi yemiyalelo yesithuthi ukuze ufumane indawo), sebenzisa i-multimeter ukuvavanya ukuba iyavuthuzwa na. Ukuba iyavuthuzwa, yitshintshe ngefuse efanayo (ungasebenzisi ucingo lobhedu endaweni yalo).
Ukuhlolwa kwecandelo eliphambili
Uvavanyo lokubuyisela:
Qalisa imoto uze uvule iswitshi ye-A/C. Mamela isandi esithi "klikha" kwi-relay.
Ukuba akukho sandi, sebenzisa i-multimeter ukuze ubone ukumelana kwe-relay coil (ixabiso eliqhelekileyo yi-50-100Ω). Ukuba ayiqhelekanga, yitshintshe.
Ukuqinisekiswa kweswitshi yokulawula ubushushu:
Susa iplagi yeswitshi yokulawula ubushushu kwaye ukhawulezise ukujikeleza iiphini. Ukuba ifeni iyajikeleza, iswitshi yonakele kwaye kufuneka itshintshwe.
Ukuba ayijikelezi, jonga ukuba i-switch circuit ivuliwe na (vavanya nge-multimeter ukuze ubone ukuqhubeka kwayo).
Ukuphatha iimpazamo ezinzulu
Ukuxilongwa kwemoto:
Nqamla umbane uze uhambise ii-fan blades ngesandla. Ukuba kukho i-jam okanye ingxolo engaqhelekanga, thambisa i-shaft ejikelezayo (sebenzisa i-oyile yokuthambisa ekhethekileyo) okanye utshintshe injini.
Uvavanyo lokuvula amandla emoto: Qhagamshela umbane we-12V, ukuba awujikelezi, yimpazamo yemoto.
Isekethe kunye neenzwa:
Jonga iikhowudi zeempazamo ze-ECU (ikhompyutha yesithuthi) usebenzisa isixhobo sokufunda i-OBD-II.
Vavanya ukumelana kwesenzi sobushushu bamanzi (kubushushu obuqhelekileyo, malunga ne-200-500Ω), ukuba ixabiso aliqhelekanga, litshintshe.
Xa ifeni ye-elektroniki yesithuthi yaphukile, inokubangela izinto ezinje ngokushisa kakhulu kwenjini, ukuvuza kwetanki yamanzi, kunye nokusebenza okungaqhelekanga kwefeni. Iimpawu ezithile ziquka ukunyuka kobushushu benjini, ukungasebenzi kakuhle kwenkqubo yokupholisa, kunye nomonakalo womzimba kwifeni. Oku kulandelayo yinkcazo eneenkcukacha zohlulo lwezi zinto:
Ukungasebenzi kakuhle kwenkqubo yokupholisa injini
Ukungasebenzi kakuhle kwefeni ye-elektroniki kuchaphazela ngqo ukusebenza kakuhle kokupholisa, nto leyo ekhokelela kwimpendulo yetsheyini:
Ubushushu benjini bunyuka kakhulu: Emva kokuba ifeni iyekile ukujikeleza, ubushushu obukwitanki yamanzi abunakunyamalala, isalathisi sokulinganisa ubushushu sinyuka ngokukhawuleza (ngesiqhelo sidlula i-95°C), isibane sesilumkiso sobushushu bamanzi kwideshibhodi siyavula, nto leyo enokubangela ukulahleka kwamandla okanye ukucima kwenjini.
Ukuqhekeka okanye ukuvuza kwetanki yamanzi: Ubushushu obuphezulu bubangela ukuba uxinzelelo olukwitanki yamanzi lunyuke kakhulu, itanki yamanzi iyaqhuma okanye isitywini siyaphela, kwaye ulwelo olupholileyo lungcolisa umhlaba. Ukujikeleza kwamanzi kuyavalwa, nto leyo ebangela ukuba injini iqhume kakhulu.
Umonakalo omkhulu wenjini: Ubushushu obuphezulu obuqhubekayo bubangela "isilinda esityibilikayo" (isithambisi singena kwisilinda), okubangela ukuxinana kwepiston, ukungasebenzi kakuhle kokuthambisa, kwaye ekugqibeleni kufuna ukulungiswa okukhulu okanye ukutshintshwa kwenjini.
Iimpawu zokusilela kwefeni ye-elektroniki
Ezi zinokufunyanwa ngokujonga ngqo okanye ngokusebenza:
Iimpawu zokutsha kunye nevumba: I-motor ventilation port coil ijika ibe mnyama kwaye ikhupha ivumba lokutsha kweplastiki okanye i-wire short-circuiting.
Ukujikeleza okucothayo okanye okumisiweyo: Kunzima ukujikelezisa ishaft ngesandla, kwaye intshukumo ayigudi (ibheyiri ayinayo ioyile okanye i-rotor ayilungelelani).
Akukho sandi sokusebenza kwefeni kwindawo yenjini, okanye akukho moya xa uyichukumisa.
Ubushushu obungaqhelekanga: Ubushushu bomphezulu wefeni bunyuka ngokukhawuleza kakhulu (buvakala bushushu okwethutyana elifutshane), nto leyo ebonisa i-internal short circuit.
Ezinye iziphumo ezinxulumene noko
Ukungasebenzi kakuhle kokupholisa umoya opholileyo: Ukungasasazeki kakuhle kobushushu kukhokelela kuxinzelelo oluphezulu kakhulu kumbhobho oxinezelekileyo we-air conditioner, nto leyo ebangela ukuba i-cooling ingasebenzi kakuhle okanye i-pipe iqhekeke.
Ingxolo engaqhelekanga: Injini iyabhajwa ize yenze izandi zokungqubana okanye iingxolo ezingaqhelekanga eziphindaphindwayo.
Isilumkiso: Xa ubushushu bamanzi bufikelela kuma-80℃, ifeni kufuneka iqalise ngokuzenzekelayo. Ukuba ayijikelezi, kufuneka ilungiswe ngoko nangoko ukuze kuthintelwe umonakalo wenjini.
