Iyini ikhoyili yokushisa imoto
Ikhoyili yokushisa yezimoto iyisici esibalulekile ohlelweni lokushisa lwezimoto, ikakhulukazi ebhekene nokuguqula i-voltage ephansi (ngokuvamile ama-volts angu-12) enikezwa yibhethri yemoto ibe yi-voltage ephezulu (ngokuvamile amashumi ezinkulungwane zama-volts) ukuze kukhiqizwe inhlansi yokushisa ingxube kaphethiloli kusilinda senjini, ngaleyo ndlela kushayelwe imoto.
Indlela esebenza ngayo
Amakhoyili okuthungela ezimoto asebenza ngesimiso sokungeniswa kwe-electromagnetic. Uma iswishi yokuthungela ivaliwe, i-voltage ephansi enikezwa yibhethri yemoto idluliselwa nge-coil eyinhloko iye kwi-coil yesibili. Ugesi kwi-coil eyinhloko uyashintsha kwi-coil yesibili, okwenza insimu enamandla yamagnetic. Lapho ugesi kwi-coil eyinhloko unqanyulwa, insimu yamagnetic iyawa ngokushesha, okubangela ukushaya okukhulu kwe-voltage kwi-coil yesibili. Lokhu kushaya kwe-voltage ephezulu kudluliswa ngentambo kuya kwi-spark plug, okudala i-spark evuthela ingxube kaphethiloli kwisilinda.
Isakhiwo sokwakheka
Amakhoyili okuthungela izimoto ngokuvamile aqukethe izingxenye ezilandelayo eziyinhloko:
Ikhoyili Eyinhloko: iqukethe izintambo zethusi ezijiyile ezixhunywe ebhethrini elihle lemoto kanye nemojuli yokulawula yesistimu yokushisa ukuze ithole ugesi oqondile we-voltage ephansi.
Ikhoyili Yesibili: iqukethe izintambo ezincane, ezivikelwe ngokushisa, ngokuvamile ezivalwe enkabeni yensimbi noma ye-magnetic, ezikhiqiza ama-pulse e-voltage ephezulu ngokufakwa kwe-electromagnetic.
I-Iron Core: isetshenziselwa ukuthuthukisa insimu ye-electromagnetic ekhiqizwa yi-coil yesibili ukuze inikeze ukuhanjiswa okungcono.
Iswishi Yokusha: Idivayisi yokushintsha elawula ikhoyili yokusha futhi eqala inqubo yokusha.
I-Control Module : qapha futhi ulawule ukusebenza kwekhoyili yokushisa, lungisa isikhathi sokushisa kanye nemvamisa yokushaya kwenhliziyo yokushisa.
Uhlobo
Amakhoyili okuthungela ezimoto ahlukaniswe kakhulu ngezinhlobo ezimbili:
ikhoyili yokushisa evulekile ye-magnetic : yenziwe ngesimiso se-electromagnetic mutual inductance, isakhiwo esilula, kodwa ukulahleka kwamandla okukhulu.
Ikhoyili yokushisa yesekethe evaliwe ye-magnetic : ukugoqa okuyinhloko kanye nokugoqa kwesibili okuzungeze umongo wensimbi, ukuvuza okuncane kwe-magnetic, izinga lokuguqulwa kwamandla aphezulu, okusetshenziswa kabanzi ohlelweni lwesimanje lokuthungela lwe-elekthronikhi.
Isenzo
Indima eyinhloko yekhoyili yokushisa ukuguqula i-voltage ephansi ibe yi-voltage ephezulu, ukuqinisekisa ukuthi i-spark plug ingakhiqiza izinhlansi ezanele zokushisa ingxube kaphethiloli, ngaleyo ndlela kuqinisekiswe ukusebenza okuvamile kanye nokushisa okubushelelezi kwenjini.
Ukwehluleka nokugcinwa
Ukwehluleka kwekhoyili yokushisa kungaholela ekuqhumeni kwenjini, ukusheshisa okubuthakathaka, ubunzima bokuqala kanye nezinye izinkinga. Izimbangela ezivamile zokwehluleka zifaka phakathi ukuguga kwekhoyili, ukwehluleka kwepulagi yenhlansi, kanye nezinkinga zomugqa. Ngesikhathi sokulungiswa, ikhodi yephutha ingafundwa, ukuhlolwa ngokubona, ukuhlolwa kokumelana nezinye izindlela zokuxilonga nokulungisa.
Ngokuqukethwe okungenhla, ungayiqonda ngokugcwele incazelo yekhoyili yokushisa yezimoto, isimiso sokusebenza, isakhiwo sokwakheka, uhlobo kanye nendima yayo ebalulekile ohlelweni lokushisa lwezimoto.
Ikhoyili yokushisa yezimoto iyisici esibalulekile ohlelweni lokushisa lwezimoto, futhi indima yayo eyinhloko ukuguqula i-voltage ephansi (ngokuvamile ama-volts angu-12) enikezwa yibhethri yemoto ibe yi-voltage ephezulu (ngokuvamile amashumi ezinkulungwane zama-volts) ukuze kukhiqizwe izinhlansi zikagesi zokushisa ingxube kaphethiloli kusilinda senjini, ngaleyo ndlela kuqinisekiswe ukusebenza okuvamile kanye nokushisa okubushelelezi kwenjini.
Umsebenzi kanye nomgomo othize
Ukuguqulwa kwe-voltage
Ikhoyili yokushisa iguqula ugesi we-low voltage ube ugesi we-high voltage ngokusebenzisa isimiso sokungeniswa kwe-electromagnetic. Lapho ikhoyili eyinhloko ixhunywe kugesi, kukhiqizwa insimu yamagnetic. Lapho idivayisi yokushintsha inqamula isekethe yekhoyili eyinhloko, insimu yamagnetic ibola ngokushesha, bese ikhoyili yesibili ibangela i-voltage ephezulu ukuze inikeze ipulaki ye-spark ukuze igxume ngomlilo.
Vuthela ingxube yegesi
Ugesi onamandla aphezulu okhiqizwa yi-ignition coil ukhiqiza inhlansi kagesi nge-spark plug, uvuthe ingxube kaphethiloli esilinda yenjini futhi uqhubekisele phambili ukunyakaza kwe-piston, ngaleyo ndlela ushayela imoto.
ivumelaniswe nezidingo zezinjini zesimanje
Njengoba izinjini zezimoto ziqhubekela phambili ngesivinini esikhulu, isilinganiso sokucindezela okuphezulu, amandla aphezulu, ukusetshenziswa kukaphethiloli okuphansi kanye nokukhishwa okuphansi komoya, izidingo zamandla zekhoyili yokushisa ziyanda ukuqinisekisa ukuthi ipulaki yenhlansi ikhiqiza inhlansi yamandla anele.
Ukubaluleka kwamakhoyili okuthungela
Ukuqala kwenjini: Uma ikhoyili yokushisa ihluleka, imoto ingase ingaqali noma ingabi nezinkinga ezifana nokujikijela okungasebenzi kahle kanye nokusheshisa okubuthakathaka.
Ukusebenza kahle kukaphethiloli: Amakhoyili okushisa asebenza kahle andisa ukusebenza kahle kukaphethiloli futhi anciphise ukusetshenziswa kukaphethiloli kanye nokukhishwa kwegesi.
Ukulungiswa nokufakwa esikhundleni
Ukuhlolwa okuvamile: Kunconywa ukuhlola ikhoyili yokushisa njalo ngamakhilomitha angu-20,000 noma ngaphezulu ukuqinisekisa ukuthi igobolondo layo alinawo uwoyela nokuthi izinsika zokubopha azikhululekile.
Umjikelezo wokufaka esikhundleni: ngaphansi kwezimo ezijwayelekile, ikhoyili yokushisa ishintshwa njalo ngamakhilomitha ayi-100,000, kodwa umjikelezo othize udinga ukulungiswa ngokuya ngokusetshenziswa kwemoto nesimo sokulungiswa.
Ngamafuphi, ikhoyili yokushisa yezimoto idlala indima ebalulekile ohlelweni lokushisa injini, futhi ukusebenza kwayo kuthinta ngqo ukuqala kwemoto, ukusebenza kwayo kanye nokusebenza kahle kukaphethiloli.
