Umsebenzi wenzwa yokushisa yangaphandle yezimoto
Umsebenzi oyinhloko wesenzi yokushisa yangaphandle yemoto ukunikeza isignali yokushisa kwendawo yangaphandle kwiyunithi yokulawula kagesi (i-ECU) yemoto . Ngemva kokuthola lezi zimpawu, i-ECU izoqhathaniswa nokushisa ngaphakathi kwemoto, ukuze ilungise ngokunembile isimo sokusebenza kwesistimu yokupholisa umoya ukuqinisekisa induduzo yendawo yangaphakathi .
Ngokukhethekile, inzwa yokushisa yangaphandle iyakwazi ukuqapha izinga lokushisa langaphandle ngesikhathi sangempela futhi inikeze lolu lwazi ku-ECU. Ngokwesignali yokushisa eyamukelwe kanye nezinga lokushisa ngaphakathi emotweni, i-ECU yenza ukuhlaziywa okuphelele, bese ilungisa ngokuhlakanipha ukusebenza kohlelo lokupholisa umoya ukuze kuhlangatshezwane nezidingo zenduduzo zabagibeli emotweni.
Ngaphezu kwalokho, inzwa yokushisa yangaphandle yemoto nayo ihilelekile ekulungisweni kweminye imisebenzi, njengezihlalo zokushisa, umsebenzi wokushisa wesiteringi, kanye nokulungiswa kwesivinini se-wiper. Ukuqaliswa kwale misebenzi kuncike esignalini yokushisa enembile enikezwa yinzwa yokushisa yangaphandle . Izimo zokusebenza zezinzwa nazo zinomthelela ekusebenzeni kahle kukaphethiloli wemoto kanye nokusebenza kokukhishwa komoya. Uma inzwa yehluleka, i-ECU ingase ingakwazi ukulawula ngokunembile inani likaphethiloli elifakwe, okuthinta ukusebenza kahle kukaphethiloli wemoto kanye nokusebenza kokukhishwa komoya.
Ngakho-ke, ukugcina inzwa yokushisa yangaphandle yemoto isesimweni esihle sokusebenza kubalulekile ukuqinisekisa ukusebenza okuvamile kwemisebenzi yemoto.
Inzwa yokushisa yangaphandle yemoto iyingxenye ebalulekile yesistimu yokupholisa umoya yemoto. Umsebenzi wayo oyinhloko ukunikeza isignali yokushisa kwendawo yangaphandle yeyunithi yokulawula kagesi (i-ECU) yemoto. Ngemva kokuthola lezi zimpawu, i-ECU izoqhathaniswa nokushisa ngaphakathi kwemoto, ukuze ilungise ngokunembile isimo sokusebenza kwesistimu yokupholisa umoya ukuqinisekisa induduzo yendawo yangaphakathi .
Isimiso sokusebenza senzwa yokushisa yangaphandle
Inzwa yokushisa yangaphandle ivame ukusebenzisa i-thermistor ye-negative temperature coefficient njengento yokuthola futhi ifakwe ku-grille yangaphambili ye-bumper intake yemoto. Iyakwazi ukuqapha izinga lokushisa langaphandle ngesikhathi sangempela futhi inikeze lolu lwazi emuva ku-ECU. I-ECU yenza ukuhlaziywa okuphelele ngokuya ngesignali yokushisa etholakele kanye nezinga lokushisa emotweni, bese ilungisa ngokuhlakanipha ukusebenza kohlelo lokupholisa umoya .
Indima yezinzwa zokushisa zangaphandle
Uhlelo lokupholisa umoya: Isignali yokushisa enikezwa yinzwa isiza i-ECU ukulungisa ngokunembile isimo sokusebenza kohlelo lokupholisa umoya ukuqinisekisa ukuthi izinga lokushisa ngaphakathi emotweni lifanelekile.
Ukusetshenziswa kukaphethiloli kanye nomphumela wokukhishwa kwegesi: Isimo sokusebenza senzwa yokushisa yangaphandle sithinta nokusetshenziswa kukaphethiloli kanye nokukhishwa kwegesi emotweni. Uma inzwa yehluleka, i-ECU ingase ingalawuli ngokunembile inani likaphethiloli elifakwayo, okuthiya ukusebenza kahle kukaphethiloli kanye nokusebenza kokukhishwa kwegesi emotweni.
Okunye ukulungiswa komsebenzi: Ngaphezu kwalokho, inzwa yokushisa yangaphandle nayo ihilelekile ekulungisweni kwesihlalo esishisayo, umsebenzi wokushisa wesondo lokuqondisa kanye nokulungiswa kwesivinini se-wiper.
Ukusebenza kwamaphutha kanye nendlela yokuthola amaphutha
Uma inzwa yokushisa yangaphandle yonakele, kungase kube nezimpawu ezilandelayo:
Izinga lokushisa elingajwayelekile eliboniswe kudeshibhodi: Izinga lokushisa eliboniswe alihambisani nezinga lokushisa langempela.
Ukuphambuka kwesilinganiso somoya-kaphethiloli wenjini: ukusebenza kwenjini kuyathinteka.
Uhlelo lokupholisa umoya lusebenza kabi: Uhlelo lokupholisa umoya lungase lungasebenzi kahle noma lungasebenzi kahle.
Indlela yokuthola ifaka phakathi ukusebenzisa i-multimeter ukukala inani lokumelana lenzwa, inani elijwayelekile kufanele libe phakathi kwama-kiloohms angu-1.6 no-1.8, uma izinga lokushisa liphansi, inani lokumelana liba likhulu. Uma ukumelana kungavamile, i-sensor harness ingase inqanyulwe noma isixhumi singaxhumani kahle. Udinga ukuhlola noma ukushintsha inzwa.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
Inkampani Zhuo Meng Shanghai Auto Co., Ltd. uzibophezele ekuthengiseni izingxenye zezimoto ze-MG&750 zamukelekile ukuthenga.
