Uyini umsebenzi wekhoyili yokushisa imoto
Indima eyinhloko yekhoyili yokushisa yezimoto ukuguqula i-voltage ephansi enikezwa yibhethri yemoto ibe yi-voltage ephezulu ukuze kukhiqizwe inhlansi kagesi evuthisa ingxube kaphethiloli kusilinda yenjini. Ngokukhethekile, ikhoyili yokushisa isebenza ngesimiso sokungeniswa kwe-electromagnetic, iguqula ugesi we-voltage ephansi ibe ugesi we-voltage ephezulu, iqinisekisa ukusebenza okuvamile kanye nokushisa okubushelelezi kwenjini.
Isimiso sokusebenza
Ikhoyili yokushisa isebenza njenge-transformer, kodwa inobunye bayo. Yakhiwe kakhulu yikhoyili eyinhloko, ikhoyili yesibili kanye ne-iron core. Lapho ikhoyili eyinhloko ivuliwe, ukwanda kwamandla kagesi kudala i-magnetic field enamandla eyizungezile, futhi i-iron core igcina amandla e-magnetic field. Lapho idivayisi yokushintsha inqamula isekethe yekhoyili eyinhloko, i-magnetic field yekhoyili eyinhloko ibola ngokushesha, futhi ikhoyili yesibili izwa i-voltage ephezulu. Lapho i-magnetic field yekhoyili eyinhloko ishesha ukunyamalala, kulapho amandla kagesi amakhulu ngesikhathi sokunqamuka kwamandla kagesi, futhi lapho isilinganiso sokujika phakathi kwamakhoyili amabili sikhulu, i-voltage ebangelwa yi-secondary coil iphakama.
Ukusebenza kwephutha kanye nomthelela
Uma ikhoyili yokushisa inephutha, izokwenza ukuthi i-spark plug yehluleke ukuvutha ngendlela evamile, okuzothinta ukusebenza okuvamile kwenjini. Ukusebenza okuqondile kufaka phakathi ukuthi imoto ayikwazi ukuqala ngendlela evamile, isivinini sokungenzi lutho asizinzile, ukusheshisa akukuhle, kanye nokukhanya kwephutha kuvuliwe. Ngaphezu kwalokho, ikhoyili yokushisa ephukile izophinde iholele ekudlidlizeni kwenjini, ukusheshisa okubuthakathaka, izinga eliphezulu akukhuphuki izimpawu .
Iseluleko sokulungisa nokulungisa
Njengoba ikhoyili yokushisa idlala indima ebalulekile emsebenzini wenjini yemoto, ukugcinwa kwayo nokugcinwa kwayo nakho kubaluleke kakhulu. Gwema ukubeka ikhoyili yokushisa emazingeni okushisa aphezulu ukuze ugweme umonakalo wemishini nokagesi. Uma ikhoyili yokushisa itholakala inephutha, kufanele ishintshwe ngesikhathi ukuqinisekisa ukusebenza okuvamile kwenjini.
Uma ikhoyili yokushisa yemoto yonakele, izinyathelo ezilandelayo kufanele zithathwe ukulungisa nokufaka esikhundleni sayo:
Hlola i-voltage kanye nokumelana : Okokuqala, vula iswishi yokushisa ibe yi-ON, susa isixhumi se-wiring harness se-ignition coil, bese usebenzisa i-multimeter ukuhlola ukuthi ngabe kukhona i-voltage engu-12V phakathi kwe-pin No. 3 kusixhumi kanye nekhebula lomhlabathi. Uma kungekho i-voltage, hlola imigqa ehlobene. Ngesikhathi esifanayo, hlola ukuthi ngabe kukhona i-short circuit noma i-open circuit phakathi kwe-pin No. 1 kanye ne-pin No. 5 ye-ECU kanye ne-pin No. 2 ye-ECU. Ngaphezu kwalokho, linganisa ukuthi ukumelana kwe-coil eyinhloko yenzwa cishe kungama-0.9Ω kanti ukumelana kwe-coil yesibili cishe kungama-14.5kΩ. Uma la manani engahlangatshezwanga, cabanga ngokufaka esikhundleni se-ignition coil.
Ifomu legagasi lokuthola : I-oscilloscope isetshenziselwa ukuthola ukuthi i-waveform yesibili yomugqa we-voltage ephezulu yesistimu yokushisa isesimweni esijwayelekile yini. Uma i-waveform ingavamile, ikhoyili yokushisa ingadinga ukushintshwa.
Shintsha ikhoyili yokushisa: Uma ushintsha ikhoyili yokushisa, qiniseka ukuthi ukhetha ikhoyili efanelana nomodeli, futhi ungacabangi ngephutha ukuthi wonke amakhoyili e-voltage efanayo asebenza kuyo yonke indawo. Ngaphezu kwalokho, izinyathelo zokuvimbela zansuku zonke nazo zibaluleke kakhulu, njengokuhlola njalo, ukuhlanza nokuqinisa ukuxhumana kwemigqa ukuze kugwenywe amasekethe amafushane noma izinkinga zokumisa phansi; Lungisa ukusebenza kwenjini ukuze kuvinjelwe i-voltage eyeqile; Futhi ugweme ukuveza ikhoyili yokushisa ekushiseni okweqile noma emswakama.
Izimbangela zomonakalo we-ignition coil zingafaka:
Ukuguga: Ikhoyili yokushisa izoguga kancane kancane ngesikhathi sokusetshenziswa, okuholela ekusebenzeni okunciphile.
ukushisa ngokweqile: ukusebenza endaweni eshisa kakhulu isikhathi eside kungabangela umonakalo ku-ignition coil.
indawo enomswakama: umswakama ungabangela ukugqwala kwezingxenye zangaphakathi zekhoyili yokushisa, okuthinta ukusebenza kwayo okuvamile.
Izinkinga zesekethe: Isekethe emfushane noma isekethe evulekile nayo ingabangela umonakalo kukhoyili yokushisa.
Izindlela zokuvimbela: Hlola isimo sekhoyili yokushisa njalo, gcina indawo yayo yokusebenza yomile, gwema ukushisa ngokweqile, bese uhlanza njalo futhi uqinise uxhumano lwentambo ukuze wandise isikhathi sayo sokusebenza.
