Ignition coil.
Nekuvandudzwa kweinjini yemota peturu kuenda kwainomhanya, yakakwira compression reshiyo, simba rakawanda, kuderera kwemafuta uye kuderera kuburitsa, chinyakare chekubatidza mudziyo chatadza kuzadzisa zvinodiwa zvekushandisa. Izvo zvakakosha zveiyo ignition mudziyo ndeye iginition coil uye switching mudziyo, inovandudza simba reiyo ignition coil, iyo spark plug inogona kuburitsa yakaringana simba spark, inova ndiyo mamiriro ekutanga emudziyo wekudzima kuti uenderane nekushanda kweinjini dzemazuva ano. .
musimboti
Iko kunowanzo kuve nemaseti maviri emakoiri mukati meiyo ignition coil, yekutanga coil uye yechipiri coil. The chepakutanga coil anoshandisa gobvu enamelled waya, kazhinji anenge 0.5-1 mm enamelled waya kumativi 200-500 anotendeuka; Iyo yechipiri coil inoshandisa yakatetepa enamelled waya, kazhinji inenge 0.1 mm enamelled waya inotenderera 15000-25000 inotendeuka. Imwe magumo eiyo yekutanga coil yakabatana kune yakaderera-voltage magetsi emagetsi (+) pamotokari, uye imwe magumo yakabatana kune switching mudziyo (breaker). Imwe magumo echipiri coil yakabatana neyekutanga coil, uye imwe magumo yakabatana neinobuda kupera kweiyo yakakwira voltage line kuburitsa yakakwira voltage.
Chikonzero nei coil yekudzima ichigona kushandura yakaderera voltage kuita yakakwira voltage pamota ndechekuti ine fomu rakafanana neyakajairwa transformer, uye yekutanga coil ine yakakura kutendeuka reshiyo pane yechipiri coil. Asi iyo ignition coil inoshanda modhi yakasiyana neyakajairika transformer, iyo yakajairwa shanduko yekushanda frequency yakagadziriswa 50Hz, inozivikanwawo semagetsi frequency transformer, uye coil yekudzima iri muchimiro chekushanda kwepulse, inogona kutorwa seye pulse transformer, iyo zvinoenderana nekumhanya kwakasiyana kweinjini pamafrequency akasiyana ekudzokororwa kwesimba rekuchengetedza uye kubuda.
Kana iyo yekutanga coil ikabatidzwa, simba remagineti rinogadzirwa rakaitenderedza sezvo ikozvino inowedzera, uye iyo magineti simba rinochengetwa musimbi core. Kana iyo switching mudziyo ikabvisa iyo yekutanga coil wekiti, iyo magineti yeiyo yekutanga coil inoora nekukurumidza, uye yechipiri coil inonzwa yakakwira voltage. Iyo inokurumidza iyo magineti yeiyo yekutanga coil inonyangarika, iyo yakakura ikozvino panguva yekudimburwa kwazvino, uye yakakura kutendeuka kwereshiyo yemakoiri maviri, iyo yakakwira voltage inokonzereswa neyechipiri coil.
Coil mhando
Ignition coil zvinoenderana neiyo magineti wedunhu yakakamurwa kuita yakavhurika magineti mhando uye yakavharwa magineti mhando mbiri. Iyo yechinyakare yekudzima coil imhando yakavhurika yemagineti, uye musimboti wayo wesimbi wakarongedzerwa ne0.3mm silicon simbi mashiti, uye kune echipiri uye ekutanga macoil akatenderedza musimboti wesimbi. Iyo yakavharwa magineti mhando inoshandisa simbi yepakati yakafanana ne Ⅲ yakatenderedza yekutanga coil, uye yobva yapeperetsa yechipiri coil kunze, uye iyo magineti yemunda mutsara inoumbwa nesimbi core. Zvakanakira zveyakavharwa magineti ignition coil ishoma kudonha kwemagineti, kurasikirwa kwesimba kudiki uye saizi diki, saka yemagetsi ignition system inowanzo shandisa yakavharwa magineti coil.
Numerical control ignition
Mune yakakwira-kumhanya peturu injini yemotokari yemazuva ano, ignition system inodzorwa nemicroprocessor, inozivikanwawo sedhijitari yemagetsi ignition system, yakagamuchirwa. Iyo ignition system ine zvikamu zvitatu: microcomputer (kombuta), akasiyana masensa uye ignition actuators.
Muchokwadi, mumainjini emazuva ano, ese ari maviri majekiseni epeturu uye ekudzimisa masisitimu anodzorwa neiyo ECU imwechete, iyo inogovera seti yemasensa. Iyo sensor inonyanya kufanana ne sensor mune yemagetsi inodzorwa peturu jekiseni system, senge crankshaft position sensor, camshaft position sensor, throttle position sensor, intake manifold pressure sensor, dedetonation sensor, etc. Pakati pavo, dedetonation sensor inonyanya kukosha. yakakosha sensor yakatsaurirwa kune inodzorwa nemagetsi kupisa (kunyanya injini ine exhaust gasi turbocharging mudziyo), inogona kutarisa kana injini dedetonation. uye dhigirii redetonation, sechiratidzo chemhinduro kuita iyo ECU kuraira kuti iwane kubatidza kumberi, kuitira kuti injini irege dedetonation uye inogona kuwana yakakwira combustion kunyatsoita.
Digital electronic ignition system (ESA) yakakamurwa kuita mhando mbiri zvichienderana nechimiro chayo: distributor type uye non-distributor type (DLI). Iyo yekuparadzira mhando yemagetsi ignition system inoshandisa chete coil yekudzima kuti igadzire yakakwira voltage, uye ipapo muparadzi anobatidza spark plug ye silinda yega yega zvichienderana nekutevedzana kwekudzima. Sezvo basa reku-off kweiyo coil yekutanga yeiginition coil inoitwa neyemagetsi ignition circuit, muparadzi akadzima mudziyo wekupwanya uye anongoridza basa rekugovera-voltage yakakura.
Maviri-cylinder ignition
Kubatidza kwemasilinda maviri kunoreva kuti masilinda maviri anogovera coil imwe chete yekubatidza, saka mhando yekubatidza iyi inogona kushandiswa chete pamainjini ane kunyange nhamba yemasilinda. Kana pamuchina we4-cylinder, kana macylinder pistons maviri ari padyo neTDC panguva imwe chete (imwe iri compression uye imwe iri kupera), maviri spark plugs anogovera coil imwechete yekudzima uye anobatidza panguva imwe chete, ipapo imwe inoshanda. kubatidza uye imwe yacho haishande, iyo yekutanga iri musanganiswa wekumanikidza kwakanyanya uye yakaderera tembiricha, iyo yekupedzisira iri mumhepo yekuburitsa gasi rekudzika kwakadzika. uye kupisa kwakanyanya. Naizvozvo, kupikisa pakati pe spark plug electrodes yezviviri zvakasiyana zvachose, uye simba rinogadzirwa harina kufanana, zvichikonzera simba rakakura kwazvo rekubatidza kunoshanda, rinoverengera 80% yesimba rose.
Kupisa kwakaparadzana
Iyo yakapatsanurwa yekudzima nzira inogovera coil yekudzima kune yega silinda, uye iyo ignition coil inoiswa yakananga pamusoro pe spark plug, iyo zvakare inobvisa yakakwira voltage waya. Iyi nzira yekupisa inowanikwa ne camshaft sensor kana nekutarisa cylinder compression kuti iwane kudzima kwakaringana, inokodzera chero nhamba yeinjini dzecylinder, kunyanya kune injini dzine mavharuvhu mana pacylinder. Nekuti iyo spark plug ignition coil musanganiswa unogona kuiswa pakati peiyo mbiri yepamusoro camshaft (DOHC), iyo gap nzvimbo inoshandiswa zvizere. Nekuda kwekukanzurwa kwemugoveri uye yakakwira voltage mutsetse, iyo simba conduction kurasikirwa uye kudonha kurasikirwa kushoma, hapana kupfeka kwemuchina, uye coil yekupisa uye spark plug yecylinder yega yega inounganidzwa pamwechete, uye yekunze simbi pasuru inoderedza zvakanyanya electromagnetic interference, iyo inogona kuve nechokwadi chekushanda kwakajairika kweinjini yemagetsi control system.
Ndokumbira utifonere kana uchida such zvigadzirwa.
