Uyini umehluko phakathi kwe-sensor yokushisa kwamanzi ne-plug ye-sensor yokushisa kwamanzi?
Inzwa yokushisa kwamanzi kanye nepulaki yesenzwa yokushisa kwamanzi kuyizinto ezimbili ezihlukene, yize zifana ngokusebenza, futhi zombili zisetshenziselwa ukuqapha izinga lokushisa kwamanzi okupholisa injini. Umehluko omkhulu phakathi kwazo yigama nendlela ezisetshenziswa ngayo. Inzwa yokushisa kwamanzi ivame ukubhekisela kunzwa efakwe endaweni yokukhipha amanzi yenjini ukuthola izinga lokushisa kwendawo yokukhipha amanzi yenjini. Ilinganisa izinga lokushisa kwamanzi okupholisa enjini bese idlulisela isignali yokushisa kuyunithi yokulawula kagesi (ECU) ukuze ilungise ukujova kukaphethiloli kanye nesikhathi sokusha. Igama lepulaki yesenzwa yokushisa kwamanzi lingase libe igama elingelona ezobuchwepheshe lesifunda esithile, futhi empeleni libhekisela kunzwa yokushisa kwamanzi. Ekulungiseni nasekulungiseni imoto, la magama amabili avame ukusetshenziswa ngokushintshana.
Indima yenzwa yokushisa kwamanzi: Inzwa yokushisa kwamanzi iyingxenye ebalulekile yesistimu yokulawula injini, engaqapha izinga lokushisa kwamanzi okupholisa injini futhi idlulisele isignali yokushisa kuyunithi yokulawula kagesi (ECU). I-ECU isebenzisa lezi zimpawu ukulungisa ukufakwa kukaphethiloli kanye nesikhathi sokushisa ukuze injini iqhubeke isebenza kahle. Uma inzwa yokushisa kwamanzi yehluleka, kungaholela ekwehleni kokusebenza kwenjini futhi kubangele nokwehluleka kwenjini. Ngakho-ke, kubaluleke kakhulu ukuhlola nokugcina inzwa yokushisa kwamanzi njalo.
Indima yenzwa yokushisa kwamanzi: Indima yenzwa yokushisa kwamanzi kanye nenzwa yokushisa kwamanzi iyafana, futhi isetshenziselwa ukuqapha izinga lokushisa kwamanzi okupholisa injini. Ekulungiseni nasekulungiseni imoto, la magama amabili avame ukusetshenziswa ngokushintshana. Uma ipulaki yenzwa yokushisa kwamanzi inephutha, ingabangela ukwehla kokusebenza kwenjini futhi ibangele nokwehluleka kwenjini. Ngakho-ke, kubaluleke kakhulu ukuhlola nokugcina ipulaki yenzwa yokushisa kwamanzi njalo.
Iyini iphutha lokusebenza kwepulaki yesenzwa yokushisa kwamanzi emotweni?
Izimpawu eziyinhloko zokwehluleka kwepulaki yesenzwa yokushisa kwamanzi yemoto zifaka phakathi ukuthi inaliti yesikhombisi sokushisa kwamanzi ayihambi noma ayikhombe endaweni ephezulu kakhulu, ubunzima bokuqala kwemoto ebandayo, ukusetshenziswa kukaphethiloli okwandisiwe, isivinini esingazinzile sokungenzi lutho, ubunzima bokusheshisa, kanye nesibani sesixwayiso sokushisa kwamanzi sephaneli yezinsimbi.
Inzwa yokushisa kwamanzi yezimoto, eyaziwa nangokuthi inzwa yokushisa kwamanzi, iyisici esibalulekile ohlelweni lokupholisa lwezimoto. Uma ipulaki yesenzwa yokushisa kwamanzi yehluleka, izobangela uchungechunge lwezimpawu ezingasiza umnikazi noma uchwepheshe ukuthi athole inkinga ngokushesha. Okulandelayo ukusebenza okuyinhloko kokwehluleka kwepulaki yesenzwa yokushisa kwamanzi yemoto:
Isilinganiso sokushisa kwamanzi sibonisa ukuthi inaliti ayinyakazi noma ikhombe endaweni ephezulu kakhulu: Uma ipulaki yesensa yokushisa kwamanzi yonakele, isilinganiso sokushisa kwamanzi singase singabonisi izinga lokushisa kwamanzi kahle. Inaliti yesikhombisi ayinyakazi noma ikhombe ngqo endaweni ephezulu kakhulu, okubonisa ukuthi isensa yokushisa kwamanzi ayikwazi ukufunda ulwazi lokushisa ngendlela efanele.
Ubunzima bokuqalisa imoto ebandayo : ngoba inzwa yokushisa kwamanzi ayikwazi ukunikeza isignali yokushisa kwamanzi enembile, i-ECU (iyunithi yokulawula kagesi) ayikwazi ukulungisa ukujiya kwengxube, okuholela engxubeni encane kakhulu lapho imoto ebandayo iqala, ngakho-ke kunzima ukuyiqala.
ukusetshenziswa kukaphethiloli okwandisiwe : Ukwehluleka kwenzwa yokushisa kwamanzi kungabangela ukuthi injini ingafinyeleli izinga lokushisa lokusebenza elifanele, okuthinta ukusebenza kahle kukaphethiloli futhi kuholele ekusetshenzisweni kukaphethiloli okwandisiwe.
i-idle engazinzile : Ngemva kokuthi inzwa yokushisa kwamanzi yonakele, injini ingase iqhume noma isebenze ngokungajwayelekile i-idle ngoba i-ECU ayikwazi ukulungisa ukuhlushwa kwengxube ngokuya ngokushisa kwamanzi kwangempela.
ubunzima bokusheshisa : Uma i-accelerator icindezelwa, isivinini senjini asikwazi ukukhushulwa ngoba i-ECU ayikwazi ukuthola isignali yokushisa kwamanzi efanele ukulungisa amandla okukhipha injini.
Iphaneli yezinsimbi Izinga lokushisa lamanzi Isibani sesexwayiso sivuliwe: Kwezinye izimo, lapho inzwa yokushisa kwamanzi inephutha, isibani sesexwayiso sokushisa kwamanzi kuphaneli yezinsimbi sizokhanya ukuze sazise umshayeli ukuthi ahlole uhlelo lokupholisa.
Ngamafuphi, ukusebenza kwephutha lenzwa yokushisa kwamanzi emotweni kuyahlukahluka, kodwa ngokubona lezi zimpawu, umnikazi noma uchwepheshe angakwazi ekuqaleni ukunquma ukuthi ngabe kukhona inkinga ngenzwa yokushisa kwamanzi, kanye nokulungiswa noma ukushintshwa ngesikhathi ukuqinisekisa ukusebenza okuvamile kwemoto nokuphepha kokushayela.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
