Umsebenzi kunye nomgaqo wekhoyili yokutsha
Ikhoyili yokutsha yemoto yinxalenye ebalulekileyo kwinkqubo yokutsha yemoto.
Ikhoyili yokutsha yemoto inoxanduva olukhulu lokuguqula i-voltage ephantsi (ngesiqhelo i-12 volts) enikezelwa yibhetri yesithuthi ibe yi-voltage ephezulu (ngesiqhelo i-amashumi amawaka e-volts) ukuvelisa i-spark yokutshisa umxube wepetroli kwiisilinda zenjini. Ikhoyili yokutsha isebenza ngokusekelwe kumgaqo wokungenisa i-electromagnetic, iguqula umbane we-voltage ephantsi ube ngumbane we-voltage ephezulu ukuqinisekisa ukusebenza okuqhelekileyo kunye nokutsha okubushelelezi kwenjini . Ikhoyili yokutsha yemoto yenziwe ikakhulu yi-coil yokutsha kunye nesixhobo sokutshintsha.
Isizathu sokuba ikhoyili yokutsha ikwazi ukuguqula umbane we-voltage ephantsi kwisithuthi ibe yi-voltage ephezulu kukuba inesimo esifanayo ne-common transformer, kwaye umlinganiselo wokujika kwekhoyili yokuqala kwikhoyili yesibini mkhulu. Nangona kunjalo, indlela yokusebenza kwekhoyili yokutsha yahlukile kweyomtshini otsha. I-common transformer isebenza ngokuqhubekayo, ngelixa ikhoyili yokutsha isebenza ngokuphindaphindiweyo. Igcina kwaye ikhuphe amandla ngokuphindaphindiweyo kumaza ahlukeneyo ngokwesantya esahlukileyo senjini.
Xa i-coil yokuqala iqhagamshelwe kumbane, kwenziwa i-magnetic field enamandla ejikeleze njengoko umbane usanda, kwaye i-iron core igcina amandla e-magnetic field. Xa isixhobo sokutshintsha siqhawula isekethe ye-coil yokuqala, i-magnetic field ye-coil yokuqala iyabola ngokukhawuleza, kwaye i-voltage ephezulu kakhulu iya kufakwa kwi-coil yesibini. Okukhona i-magnetic field ye-coil yokuqala iphela ngokukhawuleza, kokukhona umbane umkhulu ngexesha lokuqhawulwa kombane, kwaye okukhona umlinganiselo wokujika kwee-coil ezimbini umkhulu, kokukhona i-voltage ephezulu ebangelwa yi-coil yesibini.
Iikhoyili zokutsha zahlulwe zibe ziintlobo ezimbini ngokweesekethe zazo zemagnethi: uhlobo oluvulekileyo lwemagnethi kunye nohlobo oluvaliweyo lwemagnethi.
Ikhoyili yokutsha yesekethe evulekileyo yemagnethi
I-open-circuit ignition coil ngokubanzi yenziwe ngesakhiwo esifana nesetini. Yenziwe ngamacwecwe esinyithi e-silicon aliqela ahlanganiswe ndawonye ukuze enze i-core efana ne-rod, kunye ne-secondary coil kunye ne-primary coil wound ngokulandelelanayo ngaphandle kwe-core. I-secondary coil inobubanzi be-wire obuyi-0 05 ukuya kwi-1mm enamel wire, kunye nee-turns ezingama-20,000 ukuya kuma-30,000. Ububanzi be-wire coil yokuqala yi-0. 5 ukuya kwi-1. I-0mm ubukhulu, ityebile kune-secondary coil, kwaye ine-turns ezili-150 ukuya kuma-300 kuphela. I-primary coil iboshwe ngaphandle kwe-secondary coil, ngoko ke utshintsho kwi-magnetic flux eveliswa yi-secondary coil ifana nqwa ne-primary coil. Izikhokelo zokujika ze-primary coil kunye ne-secondary coil ziyafana. Isiphelo sokuqala se-secondary coil siqhagamshelwe kwi-high-voltage output connector, kwaye isiphelo sayo siqhagamshelwe kwisiphelo sokuqala se-primary coil kunye ne-"+" terminal ye-housing. Isiphelo sekhoyili eyintloko siqhagamshelwe kwisiphelo sendlu "I" nakwisiqokeleli se-transistor yamandla engaphakathi kwi-igniter. I-igniter ilawula ukucima kombane kwikhoyili eyintloko.
Ikhoyili yokutsha yesekethe evaliweyo enemagnethi
Ingaphakathi lekhoyili yokukhanyisa yesekethe evaliweyo ivalekile, kwaye yonke i-magnetic flux idlula ngaphakathi kwe-core. Ukungena kwe-magnetic kwe-core kuphantse kube ngamawaka alishumi kunomoya. Ke ngoko, ukuba ikhoyili yokukhanyisa yesekethe evulekileyo ye-magnetic ifuna ukufikelela kwi-magnetic flux efanayo nekhoyili yokukhanyisa yesekethe evaliweyo, ikhoyili yayo ephambili kufuneka ibe ne-magnetic emf enkulu (ii-ampere-turns). Ke ngoko, iikhoyili zokuqala ezinee-turns ezingaphezulu kunye nobubanzi obukhulu bee-wire kufuneka zamkelwe. Inani lee-turns kwikhoyili yokuqala likhulu. Ukuba umlinganiselo ofanayo we-turns uza kufezekiswa, inani lee-turns kwikhoyili yesibini nalo kufuneka landiswe. Ke ngoko, i-miniaturization yekhoyili yokukhanyisa yesekethe evulekileyo ayinakwenzeka. Ngokwahlukileyo koko, kwikhoyili yokukhanyisa yesekethe evaliweyo ye-magnetic, ngenxa yokumelana kwayo okuphantsi kwe-magnetic, inokunciphisa ngempumelelo i-magnetic emf yekhoyili kwaye inciphise i-ignition coil. Okwangoku, ikhoyili yokukhanyisa yesekethe evaliweyo ye-magnetic ivalekile yenziwe yaba yi-miniaturized kwaye inokudityaniswa ne-igniter njengenye, okanye idityaniswe ne-spark plug. Vuthela igesi ecinezelweyo evuthayo kwisilinda nge-spark plug. Ikhoyili yokukhanyisa yendabuko yohlobo lwe-open-magnetic. Umbindi wayo wenziwe ngokubeka amaphepha esinyithi e-silicon malunga nobukhulu obuyi-0.3 millimeters, kwaye iikhoyili zesibini nezeprayimari zijikelezwe umbindi. Uhlobo lwe-closed-magnetic lusebenzisa umbindi wesinyithi ofana nohlobo Ⅲ ukujija ikhoyili yokuqala, uze ujije ikhoyili yesibini ngaphandle. Imigca ye-magnetic field yenza isekethe ye-magnetic evaliweyo ngumbindi wesinyithi. Iingenelo zekhoyili yokukhanyisa evaliweyo kukuvuza okuncinci kwe-magnetic, ukulahleka kwamandla okuncinci kunye nobukhulu obuncinci. Ke ngoko, ikhoyili yokukhanyisa evaliweyo isetyenziswa kakhulu kwiinkqubo zokukhanyisa ze-elektroniki.
