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.
Uhlobo lwekhoyili
Ikhoyili yokuthungela ngokwesekethe kazibuthe ihlukaniswe yaba uhlobo oluvulekile lukazibuthe futhi luvalwe uhlobo lukazibuthe lwesibili. Ikhoyili yendabuko yokuthungela iwuhlobo oluvulekile lukazibuthe, futhi umgogodla wayo wensimbi upakishwe ngamashidi ensimbi ayi-silicon angu-0.3mm, futhi kukhona amakhoyili esibili nawokuqala azungeze umgogodla wensimbi. Uhlobo lukazibuthe oluvaliwe lusebenzisa umgogodla wensimbi ofana nokuthi Ⅲ uzungeze ikhoyili eyinhloko, bese uphendukisa ikhoyili yesibili ngaphandle, futhi umugqa wenkundla kazibuthe wakhiwe ingqikithi yensimbi. Izinzuzo zekhoyili yokushisa kazibuthe evaliwe ukuvuza kukazibuthe okuncane, ukulahlekelwa amandla amancane kanye nosayizi omncane, ngakho isistimu yokuthungela nge-elekthronikhi ngokuvamile isebenzisa ikhoyili evaliwe kazibuthe.
Ukuthungela kokulawula izinombolo
Enjinini kaphethiloli enesivinini esikhulu yemoto yesimanje, isistimu yokuthungela elawulwa yi-microprocessor, eyaziwa nangokuthi i-digital electronic ignition system, yamukelwe. Uhlelo lokuthungela luqukethe izingxenye ezintathu: i-microcomputer (ikhompyutha), izinzwa ezihlukahlukene kanye nama-activator okuthungela.
Eqinisweni, ezinjinini zanamuhla, kokubili umjovo kaphethiloli kanye nezinhlelo ezingaphansi zokuthungela zilawulwa yi-ECU efanayo, ehlanganyela isethi yezinzwa. Inzwa ngokuyisisekelo iyafana nenzwa ohlelweni lomjovo kaphethiloli olawulwa nge-elekthronikhi, njengenzwa yesikhundla se-crankshaft, inzwa ye-camshaft position, inzwa ye-throttle position, inzwa yokucindezela edonsayo, inzwa ye-dedetonation, njll. Phakathi kwazo, inzwa ye-dedetonation iyinzwa kakhulu. inzwa ebalulekile enikezelwe ukuthungela okulawulwa nge-elekthronikhi (ikakhulukazi injini ene-exhaust gas turbocharging device), ekwazi ukuqapha ukuthi injini i-dedetonation kanye nezinga le-dedetonation, njengesignali yempendulo yokwenza umyalo we-ECU ukufeza ukuthungela kusengaphambili, ukuze injini ingeke i-dedetonation futhi ingathola ukusebenza kahle okuphezulu komlilo.
I-Digital electronic ignition system (ESA) ihlukaniswe yaba izinhlobo ezimbili ngokuya ngesakhiwo sayo: uhlobo lokusabalalisa kanye nohlobo olungasabalalisi (DLI). Isistimu ye-electronic ignition yohlobo lokusabalalisa isebenzisa ikhoyili eyodwa kuphela yokuthungela ukuze ikhiqize amandla kagesi aphezulu, bese umsabalalisi uthungela i-spark plug yesilinda ngasinye ngokulandelana kokulandelana komlilo. Njengoba umsebenzi wokucisha wekhoyili yokuqala yekhoyili yokuthungela wenziwa yisekethe ye-electronic ignition, umsabalalisi ukhansele umshini wokuphula futhi udlala kuphela umsebenzi wokusabalalisa i-voltage ephezulu.
Ukuthungela okunamasilinda amabili
I-two-cylinder ignition isho ukuthi amasilinda amabili asebenzisa ikhoyili eyodwa yokuthungela, ngakho lolu hlobo lokubasa lungasetshenziswa kuphela ezinjinini ezinenombolo elinganayo yamasilinda. Uma emshinini oyi-4-cylinder, lapho ama-cylinder pistons amabili eseduze ne-TDC ngesikhathi esisodwa (eyodwa iyi-compression kanti enye i-exhaust), ama-spark plugs amabili ahlanganyela ikhoyili efanayo yokuthungela futhi avutha ngesikhathi esifanayo, khona-ke eyodwa iyasebenza. ukuthungela kanti enye ayisebenzi kahle, eyokuqala ixubene nomfutho ophakeme kanye nezinga lokushisa eliphansi, lena yakamuva isegesi yokukhipha umfutho ophansi. kanye nezinga lokushisa eliphezulu. Ngakho-ke, ukumelana phakathi kwama-electrode e-spark plug kokubili kuhluke ngokuphelele, futhi amandla akhiqizwayo awafani, okuholela emandleni amakhulu kakhulu okuthungela okuphumelelayo, okubalela cishe u-80% wawo wonke amandla.
Ukuthungela okuhlukile
Indlela ehlukile yokuthungela yabela ikhoyili yokuthungela kusilinda ngasinye, futhi ikhoyili yokuthungela ifakwa ngokuqondile phezu kwepulaki ye-spark, ephinde iqede intambo kagesi ephezulu. Le ndlela yokushisa ifinyelelwa yinzwa ye-camshaft noma ngokuqapha ukucindezelwa kwesilinda ukuze kuzuzwe ukuthungela okunembile, ifanele noma iyiphi inombolo yezinjini zamasilinda, ikakhulukazi izinjini ezinama-valve angu-4 isilinda ngasinye. Ngenxa yokuthi inhlanganisela yekhoyili ye-spark plug ignition ingafakwa phakathi kwe-dual overhead camshaft (DOHC), isikhala segebe sisetshenziswa ngokugcwele. Ngenxa yokukhanselwa komsabalalisi kanye nolayini we-voltage ephezulu, ukulahleka kokuqhutshwa kwamandla kanye nokulahleka kokuvuza kuncane, akukho ukugqokwa komshini, futhi ikhoyili yokuthungela kanye ne-spark plug yesilinda ngasinye kuhlanganiswe ndawonye, futhi iphakethe lensimbi langaphandle linciphisa kakhulu ukuphazamiseka kwe-electromagnetic, okungaqinisekisa ukusebenza okujwayelekile kwesistimu yokulawula i-elekthronikhi yenjini.
