Ikhoyili yokushisa.
Njengoba injini kaphethiloli yemoto ithuthukiswe ngendlela yesivinini esikhulu, isilinganiso sokucindezela okuphezulu, amandla aphezulu, ukusetshenziswa kukaphethiloli okuphansi kanye nokukhishwa okuphansi komoya, idivayisi yokushisa yendabuko ayikwazanga ukuhlangabezana nezidingo zokusetshenziswa. Izingxenye eziyinhloko zedivayisi yokushisa yi-coil yokushisa kanye nedivayisi yokushintsha, okuthuthukisa amandla e-coil yokushisa, i-spark plug ingakhiqiza i-spark yamandla eyanele, okuyisimo esiyisisekelo sedivayisi yokushisa ukuze ivumelane nokusebenza kwezinjini zesimanje.
isimiso
Ngokuvamile kuba namasethi amabili amakhoyili ngaphakathi kwekhoyili yokushisa, ikhoyili eyinhloko kanye nekhoyili yesibili. Ikhoyili eyinhloko isebenzisa ucingo olujiyile olune-enamel, ngokuvamile ucingo olune-enamel oluyi-0.5-1 mm cishe luzungeze amajika angu-200-500; Ikhoyili yesibili isebenzisa ucingo oluncane olune-enamel, ngokuvamile ucingo olune-enamel oluyi-0.1 mm cishe luzungeze amajika angu-15000-25000. Ukuphela kwekhoyili eyinhloko kuxhunywe kugesi ophansi (+) emotweni, kanti okunye kuxhunywe kudivayisi yokushintsha (i-breaker). Ukuphela kwekhoyili yesibili kuxhunywe nekhoyili eyinhloko, kanti okunye kuxhunywe nokuphela kokuphuma komugqa we-voltage ephezulu ukuze kuphume i-voltage ephezulu.
Isizathu sokuthi ikhoyili yokushisa ingaguqula i-voltage ephansi ibe yi-voltage ephezulu emotweni ukuthi inesimo esifanayo ne-transformer evamile, futhi ikhoyili eyinhloko inesilinganiso sokujika esikhulu kunekhoyili yesibili. Kodwa imodi yokusebenza kwekhoyili yokushisa ihlukile kune-transformer evamile, imvamisa yokusebenza kwe-transformer evamile iqinile i-50Hz, eyaziwa nangokuthi i-power frequency transformer, kanti ikhoyili yokushisa isesimweni somsebenzi we-pulse, ingabhekwa njenge-pulse transformer, ngokwejubane elihlukile lenjini kumaza ahlukene okugcina amandla nokukhipha amandla okuphindaphindiwe.
Uma ikhoyili eyinhloko ivuliwe, kukhiqizwa insimu enamandla yamagnetic nxazonke njengoba ugesi ukhuphuka, futhi amandla ensimu yamagnetic agcinwa enkabeni yensimbi. Lapho idivayisi yokushintsha inqamula isekethe yekhoyili eyinhloko, insimu yamagnetic yekhoyili eyinhloko ibola ngokushesha, futhi ikhoyili yesibili izwa i-voltage ephezulu. Lapho insimu yamagnetic yekhoyili eyinhloko ishesha ukunyamalala, ugesi omkhulu ngesikhathi sokunqamuka kogesi, futhi lapho isilinganiso sokujika kwamakhoyili amabili sikhulu, kulapho i-voltage ebangelwa ikhoyili yesibili iphakama khona.
Uhlobo lwekhoyili
Ikhoyili yokushisa ngokusho kwesekethe yamagnetic ihlukaniswe ngohlobo oluvulekile lwe-magnetic kanye nohlobo lwesibili lwe-magnetic oluvaliwe. Ikhoyili yokushisa yendabuko iwuhlobo oluvulekile lwe-magnetic, futhi i-iron core yayo ihlanganiswe ngamashidi ensimbi e-silicon angu-0.3mm, futhi kukhona amakhoyili esibili kanye nayinhloko azungeze i-iron core. Uhlobo lwe-magnetic oluvaliwe lusebenzisa i-iron core efana ne-Ⅲ ezungeze i-primary coil, bese ivala i-secondary coil ngaphandle, bese umugqa wensimu yamagnetic wakhiwa yi-iron core. Izinzuzo ze-iron magnetic ignition coil evaliwe ukuvuza okuncane kwe-magnetic, ukulahlekelwa kwamandla amancane kanye nosayizi omncane, ngakho-ke uhlelo lwe-electronic ignition ngokuvamile lusebenzisa i-iron magnetic ignition coil evaliwe.
Ukushisa kokulawula izinombolo
Enjinini kaphethiloli enesivinini esikhulu yezimoto zanamuhla, uhlelo lokushisa olulawulwa yi-microprocessor, eyaziwa nangokuthi uhlelo lokushisa lwe-elekthronikhi yedijithali, selwamukelwe. Uhlelo lokushisa luqukethe izingxenye ezintathu: i-microcomputer (ikhompyutha), izinzwa ezahlukahlukene kanye nama-actuator okushisa.
Eqinisweni, ezinjinini zanamuhla, kokubili i-petrol injection kanye ne-ignition subsystems zilawulwa yi-ECU efanayo, ehlanganyela isethi yezinzwa. Inzwa ngokuyisisekelo ifana nenzwa ohlelweni lwe-petrol injection olulawulwa ngogesi, njenge-crankshaft position sensor, camshaft position sensor, intake manifold pressure sensor, dedetonation sensor, njll. Phakathi kwazo, i-dedetonation sensor iyinzwa ebaluleke kakhulu ezinikele ekushiseni okulawulwa ngogesi (ikakhulukazi injini ene-exhaust gas turbocharging device), engabheka ukuthi i-engine dedetonation kanye nezinga le-dedetonation, njengesignali yempendulo yokwenza umyalo we-ECU wokufeza ukushiswa kusenesikhathi, ukuze injini ingashisi futhi ithole ukusebenza kahle okukhulu kokushiswa.
Uhlelo lokuthungela ngogesi lwedijithali (i-ESA) luhlukaniswe ngezinhlobo ezimbili ngokwesakhiwo salo: uhlobo lokusabalalisa kanye nohlobo olungasabalalisi (i-DLI). Uhlelo lokuthungela ngogesi lohlobo lokusabalalisa lusebenzisa ikhoyili eyodwa kuphela yokushisa ukukhiqiza i-voltage ephezulu, bese umsabalalisi evuthela i-spark plug yesilinda ngasinye ngokulandelana ngokwendlela yokuthungela. Njengoba umsebenzi wokuvula ikhoyili eyinhloko yekhoyili yokushisa wenziwa yisekethe yokuthungela ngogesi, umsabalalisi ukhansele idivayisi ye-breaker futhi udlala kuphela umsebenzi wokusatshalaliswa ngogesi ophezulu.
Ukushiswa kwamasilinda amabili
Ukushiswa kwamasilinda amabili kusho ukuthi amasilinda amabili abelana ngekhoyili eyodwa yokushiswa, ngakho lolu hlobo lokushiswa lungasetshenziswa kuphela ezinjinini ezinenani elifanayo lamasilinda. Uma kumshini wamasilinda amane, lapho ama-piston amabili amasilinda eseduze ne-TDC ngesikhathi esisodwa (esinye sicindezelwa kanti esinye sikhipha umoya), ama-spark plug amabili abelana ngekhoyili efanayo yokushiswa futhi avutha ngesikhathi esifanayo, khona-ke elinye liyasebenza ukushiswa kanti elinye lisebenza ukushiswa, elokuqala lisengxubeni yokucindezela okuphezulu kanye nokushisa okuphansi, elokugcina lisegesini yokushiswa ephansi kanye nokushisa okuphezulu. Ngakho-ke, ukumelana phakathi kwama-electrode e-spark plug amabili kuhlukile ngokuphelele, futhi amandla akhiqizwayo awafani, okuholela emandleni amakhulu kakhulu okushiswa okuphumelelayo, okubalelwa cishe ku-80% wamandla aphelele.
Ukushiswa okuhlukile
Indlela ehlukile yokushisa inika ikhoyili yokushisa isilinda ngasinye, futhi ikhoyili yokushisa ifakwe ngqo phezu kwepulaki yenhlansi, ephinde isuse ucingo olunamandla aphezulu. Le ndlela yokushisa ifinyelelwa yinzwa ye-camshaft noma ngokuqapha ukucindezelwa kwesilinda ukuze kufezwe ukusha okunembile, ifanele noma yiliphi inani lezinjini zesilinda, ikakhulukazi ezinjinini ezinama-valve angu-4 ngesilinda ngasinye. Ngenxa yokuthi inhlanganisela yekhoyili yokushisa isilinda ingafakwa phakathi kwe-camshaft engenhla emibili (DOHC), isikhala sesikhala sisetshenziswa ngokugcwele. Ngenxa yokukhanselwa komugqa wokusabalalisa kanye nowe-voltage ephezulu, ukulahlekelwa kokuqhuba amandla kanye nokulahlekelwa ukuvuza kuncane, akukho ukuguguleka komshini, futhi ikhoyili yokushisa kanye nepulaki yenhlansi yesilinda ngasinye kuhlanganiswe ndawonye, futhi iphakheji yensimbi yangaphandle inciphisa kakhulu ukuphazamiseka kwe-electromagnetic, okungaqinisekisa ukusebenza okuvamile kohlelo lokulawula ngogesi lwenjini.
