Umsebenzi wenzwa yobushushu bangaphandle beemoto
Umsebenzi ophambili wesenzi sobushushu bangaphandle semoto kukubonelela ngesignali yobushushu bendalo yangaphandle kwiyunithi yolawulo lwe-elektroniki (ECU) yesithuthi . Emva kokufumana ezi signali, i-ECU iya kuthelekisa nobushushu obungaphakathi emotweni, ukuze ilungise ngokuchanekileyo imeko yokusebenza kwenkqubo yomoya opholileyo ukuqinisekisa intuthuzelo yendalo yangaphakathi .
Ngokukodwa, isenzi sobushushu bangaphandle siyakwazi ukujonga ubushushu be-ambient bangaphandle ngexesha langempela size sibuyisele olu lwazi kwi-ECU. Ngokwesiginali yobushushu efunyenweyo kunye nobushushu obungaphakathi emotweni, i-ECU yenza uhlalutyo olupheleleyo, ize emva koko ilungise ngobuchule ukusebenza kwenkqubo yomoya ukuze ihlangabezane neemfuno zokukhululeka zabakhweli emotweni.
Ukongeza, isenzi sobushushu bangaphandle semoto sikwabandakanyeka ekuhlengahlengisweni kweminye imisebenzi, efana nezihlalo zokufudumeza, umsebenzi wokufudumeza ivili lokuqhuba, kunye nokulungiswa kwesantya sewiper. Ukuphunyezwa kwale misebenzi kuxhomekeke kuphawu lobushushu oluchanekileyo olubonelelwa sisisenzi sobushushu bangaphandle . Iimeko zokusebenza kwezi senzi nazo zinefuthe ekusebenzeni kakuhle kwepetroli yesithuthi kunye nokusebenza kokukhupha umbane. Ukuba isenzi siyasilela, i-ECU isenokungakwazi ukulawula ngokuchanekileyo ubungakanani bepetroli efakwe kwisithuthi, nto leyo echaphazela ukusebenza kakuhle kwepetroli yesithuthi kunye nokusebenza kokukhupha umbane.
Ke ngoko, ukugcina isenzi sobushushu bemoto sisebenza kakuhle kubalulekile ukuqinisekisa ukusebenza okuqhelekileyo kwemisebenzi yemoto.
I-sensor yobushushu bangaphandle yemoto yinxalenye ebalulekileyo yenkqubo yomoya opholileyo yemoto. Umsebenzi wayo ophambili kukubonelela ngesignali yobushushu bangaphandle beyunithi yokulawula ye-elektroniki (ECU) yesithuthi. Emva kokufumana ezi signali, i-ECU iya kuthelekisa nobushushu obungaphakathi emotweni, ukuze ilungise ngokuchanekileyo imeko yokusebenza kwenkqubo yomoya opholileyo ukuqinisekisa intuthuzelo yendawo yangaphakathi .
Umgaqo wokusebenza we-sensor yobushushu yangaphandle
I-sensor yobushushu yangaphandle idla ngokusebenzisa i-thermistor ye-negative temperature coefficient njengento yokufumanisa kwaye ifakwe kwi-grille yangaphambili ye-bumper intake yemoto. Iyakwazi ukujonga ubushushu be-ambient bangaphandle ngexesha langempela kwaye ibuyisele olu lwazi kwi-ECU. I-ECU yenza uhlalutyo olupheleleyo ngokwesignali yobushushu efunyenweyo kunye nobushushu emotweni, ize emva koko ilungise ngobuchule ukusebenza kwenkqubo yomoya opholileyo .
Indima yezinzwa zobushushu zangaphandle
Inkqubo yomoya opholileyo: Isignali yobushushu enikezelwa yi-sensor inceda i-ECU ukuba ilungise ngokuchanekileyo imeko yokusebenza kwenkqubo yomoya opholileyo ukuqinisekisa ukuba ubushushu ngaphakathi emotweni bufanelekile.
Impembelelo yokusetyenziswa kwepetroli kunye nokukhutshwa kwegesi: Imeko yokusebenza kwesensa yobushushu yangaphandle ikwachaphazela ukusetyenziswa kwepetroli kunye nokukhutshwa kwegesi kwisithuthi. Ukuba isensa iyasilela, i-ECU isenokungalawuli ngokuchanekileyo ubungakanani bepetroli efakwayo, nto leyo echaphazela ukusebenza kakuhle kwepetroli kwisithuthi kunye nokusebenza kokukhutshwa kwegesi.
Olunye uhlengahlengiso lomsebenzi: Ukongeza, isenzi sobushushu sangaphandle sikwabandakanyeka ekuhlengahlengisweni kwesihlalo esishushu, umsebenzi wokufudumeza wevili lokuqhuba kunye nohlengahlengiso lwesantya sewiper.
Indlela yokusebenza kunye nendlela yokufumanisa iimpazamo
Ukuba inzwa yobushushu yangaphandle yonakele, ezi mpawu zilandelayo zinokwenzeka:
Ubushushu obungaqhelekanga obuboniswe kwideshibhodi: Ubushushu obuboniswayo abuhambelani nobushushu bokwenyani.
Ukuphazamiseka komlinganiselo womoya-ipetroli yenjini: ukusebenza kwenjini kuyachaphazeleka.
Inkqubo yomoya opholileyo ayisebenzi kakuhle: Inkqubo yomoya opholileyo isenokungasebenzi kakuhle okanye ingasebenzi kakuhle.
Indlela yokufumanisa ibandakanya ukusebenzisa i-multimeter ukulinganisa ixabiso lokuxhathisa lesensor, ixabiso eliqhelekileyo kufuneka libe phakathi kwe-1.6 kunye ne-1.8 kiloohms, okukhona ubushushu buphantsi, kokukhona ixabiso lokuxhathisa liphezulu. Ukuba ukuxhathisa akuqhelekanga, i-sensor harness isenokungaxhunywa okanye isixhumi singahambelani kakuhle. Kuya kufuneka ujonge ngakumbi okanye utshintshe isensor.
