Ikhoyili yokuthungela
Ngokuthuthukiswa kwenjini yemoto kaphethiloli eya lapho iqonde khona isivinini esikhulu, isilinganiso sokucindezela okuphezulu, amandla aphezulu, ukusetshenziswa kukaphethiloli okuphansi kanye nokukhipha umoya omncane, idivayisi yokuthungela yendabuko ayikwazanga ukuhlangabezana nezidingo zokusetshenziswa. Izingxenye eziyinhloko zedivayisi yokuthungela i-coil yokuthungela kanye nedivaysi yokushintsha, ithuthukisa amandla ekhoyili yokuthungela, i-spark plug ingakhiqiza i-spark yamandla eyanele, okuyisimo esiyisisekelo sedivayisi yokuthungela ukuze ivumelane nokusebenza kwezinjini zesimanje. .
Kukhona amasethi amabili wamakhoyili ngaphakathi kwekhoyili yokuthungela, ikhoyili yokuqala kanye neyesibili. Ikhoyili eyinhloko isebenzisa intambo enoqweqwe oluqinile, ngokuvamile ecishe ibe yi-0.5-1 mm yocingo olunameli oluzungeze ukuphenduka kuka-200-500; Ikhoyili yesibili isebenzisa intambo enoqweqwe oluncane oluncane, ngokuvamile olucishe lube ngu-0.1 mm intambo enoqweqwe lwawo ezungeze ukuphenduka kuka-15000-25000. Ingxenye eyodwa yekhoyili eyinhloko ixhunywe kugesi we-voltage ephansi (+) emotweni, kanti enye ixhunywe kudivayisi yokushintsha (i-breaker). Ingxenye eyodwa yekhoyili yesibili ixhunywe nekhoyili eyinhloko, kanti enye ixhunywe ekugcineni komugqa we-voltage ephezulu ukuze ikhiphe amandla kagesi aphezulu.
Isizathu esenza ikhoyili yokuthungela ikwazi ukuguqula i-voltage ephansi ibe yi-voltage ephezulu emotweni ukuthi inesimo esifanayo ne-transformer evamile, futhi ikhoyili eyinhloko ine-turn ratio enkulu kunekhoyili yesibili. Kodwa imodi yokusebenza yekhoyili yokuthungela ihlukile kune-transformer evamile, imvamisa yokusebenza ye-transformer evamile i-50Hz, eyaziwa nangokuthi i-power frequency transformer, futhi ikhoyili yokuthungela isesimweni somsebenzi we-pulse, ingabhekwa njenge-pulse transformer, ngokwejubane elihlukile lenjini kumafrikhwensi ahlukene wokugcinwa kwamandla okuphindaphindiwe nokukhipha.
Lapho ikhoyili eyinhloko ikhanya, insimu enamandla kazibuthe ikhiqizwa eduze kwayo njengoba inyuka, futhi amandla kazibuthe agcinwa kumongo wensimbi. Lapho idivayisi yokushintsha inqamula isekethe yekhoyili eyinhloko, inkambu kazibuthe yekhoyili eyinhloko ibola ngokushesha, futhi ikhoyili yesibili izwa amandla kagesi aphezulu. Lapho inkambu kazibuthe yekhoyili eyinhloko ishabalala ngokushesha, iba nkulu amandla amanje ngesikhathi sokunqanyulwa kwamanje, futhi uma sikhulu isilinganiso sokujika samakhoyili amabili, siphakama i-voltage ebangelwa ikhoyili yesibili.
Ngaphansi kwezimo ezijwayelekile, impilo yekhoyili yokuthungela incike ekusetshenzisweni kwendawo ezungezile kanye nokusetshenziswa kwemoto, futhi ngokuvamile idinga ukushintshwa ngemva kweminyaka emi-2-3 noma amakhilomitha angu-30,000 kuya kwangu-50,000.
Ikhoyili yokuthungela iyingxenye ebalulekile yesistimu yokuthungela injini yezimoto, indima yayo enkulu ukuguqula amandla kagesi aphansi wemoto abe ugesi onamandla ukuze kuthungele igesi exutshwe kusilinda nokukhuthaza ukusebenza kwenjini.
Kodwa-ke, uma kutholakala ukuthi injini inzima ukuqalisa, ukusheshisa akuzinzile, futhi ukusetshenziswa kukaphethiloli kuyanda, kubalulekile ukuhlola ukuthi ikhoyili yokuthungela idinga ukushintshwa ngesikhathi. Ukwengeza, ukushintshwa kwekhoyili yokuthungela nakho kudingeka kwenziwe ngochwepheshe ukuze baqinisekise ukuthi ikhoyili yomlilo eshintshiwe ingasebenza ngendlela evamile futhi igweme okunye ukwehluleka okubangelwa ukusebenza ngendlela engafanele.
Isakhiwo sekhoyili yokuthungela. Ikhoyili yokuthungela ihlukaniswe izingxenye ezimbili: ikhoyili yokuqala kanye nekhoyili yesibili. Ikhoyili eyinhloko yenziwe ngentambo enoqweqwe oluqinile, enye ingxenye yayo ixhunywe kutheminali ephozithivu ye-voltage encane kagesi emotweni kanti enye ixhunywe kudivayisi yokushintsha (i-circuit breaker).
Ikhoyili yesibili yenziwe ngocingo oluhle kakhulu olunameyili, enye ingxenye ixhunywe kukhoyili eyinhloko, kanti enye ixhunywe ekugcineni kokuphuma kwentambo ye-voltage ephezulu ukuze ikhiphe ugesi we-voltage ephezulu. Ikhoyili yokuthungela ngokuya ngesekhethi kazibuthe ingahlukaniswa ibe uhlobo oluvulekile lukazibuthe futhi luvale uhlobo lukazibuthe lwesibili. Ikhoyili yendabuko yokuthungela i-open-magnetic, ingqikithi yayo yenziwe ngeshidi lensimbi ye-silicon engu-0.3mm, amakhoyili esibili kanye nayinhloko alimala kumongo wensimbi; Okubiyelwe ikhoyili eyinhloko enomongo wensimbi, ikhoyili yesibili isongelwe ngaphandle, futhi umugqa wensimu kazibuthe wakhiwe inkaba yensimbi ukuze kwakheke isekethe kazibuthe evaliwe.
Izinyathelo zokuphepha zokushintshwa kwekhoyili. Ukushintshwa kwekhoyili yokuthungela kudinga ukwenziwa uchwepheshe, ngoba ukushintshwa okungafanele kungase kubangele okunye ukwehluleka. Ngaphambi kokushintsha ikhoyili yokuthungela, nqamula imoto kugesi, khipha ikhoyili yokuthungela, bese ubheka ukuthi ezinye izinto zonakele noma zandala, njengama-spark plug, amakhoyili amakhoyili okuvutha, namamojula amakhoyili okubasa.
Uma ezinye izingxenye zitholakala zinephutha, kufanele futhi zishintshwe. Ngemva kokufaka ikhoyili yokuthungela, kuyadingeka ukwenza ukulungisa iphutha kwesistimu ukuze kuqinisekiswe ukuqala nokusebenza okujwayelekile kwenjini, futhi ugweme izimo ezingavamile ezifana nobunzima bokuqalisa, ukuntengantenga kwesivinini, kanye nokwanda kokusetshenziswa kukaphethiloli.
Indima yekhoyili yokuthungela. Iqhaza elikhulu lekhoyili yokuthungela ukuguqula amandla ane-voltage ephansi abe ugesi onamandla kagesi ukuze kuthungele ingxube yegesi kusilinda bese iphusha injini ukuthi isebenze. Umgomo wokusebenza wekhoyili yokuthungela ukusebenzisa umgomo wokungeniswa kukazibuthe kagesi ukuze kuguqulwe amandla kagesi ane-voltage ephansi yemoto ibe ugesi we-voltage ephezulu, ukuze i-spark plug ikhiqize izinhlansi futhi ithungele igesi exubile.
Ngakho-ke, ukusebenza kanye nekhwalithi yekhoyili yokuthungela ibalulekile ekusebenzeni okuvamile kwenjini. Uma ikhoyili yokuthungela ihluleka, lokho kuzoholela ebunzimeni ekuqaliseni injini, ukusheshisa okungazinzile, ukwanda kokusetshenziswa kukaphethiloli nezinye izinkinga, kuphazamise kakhulu ukuphepha nokunethezeka kwemoto.
Ngamafuphi nje, ikhoyili ye-ignition iyingxenye ebalulekile yesistimu yokushisa injini yezimoto futhi idinga ukuhlolwa futhi ishintshwe njalo ukuze kuqinisekiswe ukuthi injini isebenza kahle. Lapho kushintsha ikhoyili yokubasa, ochwepheshe kudingeka banake ukuze bahlole ukuthi azikho yini izinkinga kwezinye izingxenye ezihlobene, futhi balungise iphutha ukuze kugwenywe okunye ukwehluleka. Ngesikhathi esifanayo, kufanele futhi siqonde isimiso sokusebenza nesakhiwo sekhoyili yokuthungela ukuze sinakekele futhi sinakekele kangcono imoto yethu.
