Ikhoyili yokutshisa.
Ngophuhliso lwenjini yepetroli yeemoto ukuya kwicala lesantya esiphezulu, umlinganiselo woxinzelelo oluphezulu, amandla aphezulu, ukusetyenziswa kwepetroli okuphantsi kunye nokukhutshwa okuphantsi komoya, isixhobo sokutsha esiqhelekileyo asikwazanga ukuhlangabezana neemfuno zokusetyenziswa. Izinto eziphambili zesixhobo sokutsha yi-ignition coil kunye nesixhobo sokutshintsha, ukuphucula amandla e-ignition coil, i-spark plug inokuvelisa amandla aneleyo e-spark, eyimeko esisiseko yesixhobo sokutsha ukuze sivumelane nokusebenza kweenjini zanamhlanje.
umgaqo
Kukho iiseti ezimbini zeekhoyili ngaphakathi kwekhoyili yokutsha, ikhoyili yokuqala kunye nekhoyili yesibini. Ikhoyili yokuqala isebenzisa ucingo olujiyileyo olune-enamel, oluhlala malunga ne-0.5-1 mm wire enamel malunga nee-turns ezingama-200-500; Ikhoyili yesibini isebenzisa ucingo olujiyileyo olune-enamel, oluhlala malunga ne-0.1 mm wire enamel malunga nee-turns ezili-15000-25000. Elinye icala lekhoyili yokuqala liqhagamshelwe kumbane we-voltage ephantsi (+) kwisithuthi, kwaye elinye icala liqhagamshelwe kwisixhobo sokutshintsha (i-breaker). Elinye icala lekhoyili yesibini liqhagamshelwe kwikhoyili yokuqala, kwaye elinye icala liqhagamshelwe nesiphelo sokukhupha somgca we-voltage ephezulu ukuya kwi-output high voltage.
Isizathu sokuba ikhoyili yokutsha ikwazi ukuguqula i-voltage ephantsi ibe yi-voltage ephezulu emotweni kukuba inohlobo olufanayo ne-transformer eqhelekileyo, kwaye ikhoyili ephambili inomlinganiselo wokujika omkhulu kunekhoyili yesibini. Kodwa indlela yokusebenza kwekhoyili yokutsha yahlukile kwi-transformer eqhelekileyo, i-frequency yokusebenza ye-transformer eqhelekileyo imiselwe yi-50Hz, ekwaziwa ngokuba yi-power frequency transformer, kwaye ikhoyili yokutsha ikwimo yomsebenzi we-pulse, ingathathwa njenge-pulse transformer, ngokwesantya esahlukileyo senjini kwiifrikhwensi ezahlukeneyo zokugcina amandla okuphindaphindiweyo kunye nokukhupha.
Xa i-coil yokuqala ivuliwe, kuvela i-magnetic field enamandla ejikeleze yona njengoko umbane usanda, kwaye amandla e-magnetic field agcinwa kwi-iron core. Xa isixhobo sokutshintsha siqhawula isekethe ye-coil yokuqala, i-magnetic field ye-coil yokuqala ibola ngokukhawuleza, kwaye i-coil yesibini iva i-voltage ephezulu. Okukhona i-magnetic field ye-coil yokuqala iphela ngokukhawuleza, kokukhona umbane usiba mkhulu ngexesha lokuqhawulwa kombane, kwaye okukhona umlinganiselo wokujika kwee-coil ezimbini umkhulu, kokukhona i-voltage ephezulu ebangelwa yi-coil yesibini.
Uhlobo lwekhoyili
Ikhoyili yokutshisa ngokwesekethe yemagnethi yahlulwe yaba luhlobo lwemagnethi oluvulekileyo kunye nohlobo lwemagnethi oluvaliweyo lwesibini. Ikhoyili yokutshisa yendabuko luhlobo lwemagnethi oluvulekileyo, kwaye isiseko sayo sesinyithi sifakwe amaphepha esinyithi e-silicon angama-0.3mm, kwaye kukho iikhoyili zesibini kunye neziphambili ezijikeleze isiseko sesinyithi. Uhlobo lwemagnethi oluvaliweyo lusebenzisa isiseko sesinyithi esifana ne-Ⅲ esijikeleze i-coil yokuqala, kwaye emva koko ijikelezisa i-coil yesibini ngaphandle, kwaye umgca wentsimi yemagnethi wenziwa yi-core yesinyithi. Iingenelo zekhoyili yokutshisa yemagnethi evaliweyo kukuvuza okuncinci kwemagnethi, ukulahleka kwamandla amancinci kunye nobukhulu obuncinci, ngoko ke inkqubo yokutshisa ye-elektroniki ngokubanzi isebenzisa i-coil yokutshisa yemagnethi evaliweyo.
Ukutshaya kolawulo lwamanani
Kwinjini yepetroli ekhawulezayo yeemoto zanamhlanje, inkqubo yokutshisa elawulwa yi-microprocessor, eyaziwa ngokuba yinkqubo yokutshisa yedijithali, iye yamkelwe. Inkqubo yokutshisa inamacandelo amathathu: i-microcomputer (ikhompyutha), ii-sensors ezahlukeneyo kunye nee-actuators zokutshisa.
Enyanisweni, kwiinjini zanamhlanje, zombini i-injection yepetroli kunye ne-ignition subsystems zilawulwa yi-ECU efanayo, ekwabelana ngeseti yee-sensors. I-sensor ngokusisiseko ifana ne-sensor kwinkqubo ye-injection yepetroli elawulwa nge-elektroniki, njenge-sensor yesikhundla se-crankshaft, i-sensor yesikhundla se-camshaft, i-sensor yesikhundla se-throttle, i-intake manifold pressure sensor, i-dedetonation sensor, njl. Phakathi kwazo, i-dedetonation sensor yi-sensor ebaluleke kakhulu ezinikele kwi-ignition elawulwa nge-elektroniki (ingakumbi injini enesixhobo se-turbocharging segesi ephumayo), enokujonga ukuba i-injini idetonation kunye nenqanaba le-dedetonation, njengomqondiso wempendulo ukwenza umyalelo we-ECU ukufezekisa i-ignition kwangaphambili, ukuze injini ingadetonation kwaye ifumane ukusebenza okuphezulu kokutsha.
Inkqubo yokutshayelela yedijithali (i-ESA) yahlulwe yaba ziintlobo ezimbini ngokwesakhiwo sayo: uhlobo lomsasazi kunye nohlobo olungasasaziyo (i-DLI). Inkqubo yokutshayelela yedijithali yohlobo lomsasazi isebenzisa ikhoyili enye yokutshayelela ukuvelisa i-voltage ephezulu, aze emva koko umsasazi atshise iplagi yespark yesilinda nganye ngokulandelana ngokwendlela yokutshayelela. Ekubeni umsebenzi wokuvula ikhoyili yokuqala yekhoyili yokutshayelela wenziwa yisekethe yokutshayelela ye-elektroniki, umsasazi urhoxisile isixhobo se-breaker kwaye udlala kuphela umsebenzi wokusasaza i-voltage ephezulu.
Ukutshaya kweesilinda ezimbini
Ukutshaya kweesilinda ezimbini kuthetha ukuba iisilinda ezimbini zabelana ngekhoyili enye yokutshaya, ngoko ke olu hlobo lokutshaya lungasetyenziswa kuphela kwiinjini ezinenani elifanayo leesilinda. Ukuba kumatshini we-4-cylinder, xa iipiston ezimbini ze-cylinder zikufutshane ne-TDC ngaxeshanye (enye icinezela kwaye enye ikhupha), iiplagi ezimbini ze-spark zabelana ngekhoyili efanayo yokutshaya kwaye zivutha ngaxeshanye, enye itshaya ngempumelelo kwaye enye itshaya ngempumelelo, eyokuqala ikumxube woxinzelelo oluphezulu kunye nobushushu obuphantsi, eyokugqibela ikwigesi yokutshaya yoxinzelelo oluphantsi kunye nobushushu obuphezulu. Ke ngoko, ukumelana phakathi kwee-electrode ze-spark plug zezi zimbini kwahlukile ngokupheleleyo, kwaye amandla aveliswayo awafani, nto leyo ebangela amandla amakhulu kakhulu okutshaya ngempumelelo, amalunga nama-80% wamandla ewonke.
Ukutshaya okwahlukileyo
Indlela eyahlukileyo yokutshaya inika ikhoyili yokutshaya kwi-cylinder nganye, kwaye ikhoyili yokutshaya ifakelwe ngqo phezu kweplagi ye-spark, ekwasusa ucingo olune-voltage ephezulu. Le ndlela yokutshaya ifezekiswa yi-sensor ye-camshaft okanye ngokujonga ucinezelo lwesilinda ukuze kufezekiswe ukutshaya ngokuchanekileyo, ifanelekile nakweyiphi na inani leenjini zesilinda, ngakumbi kwiinjini ezineevalvu ezi-4 kwisilinda nganye. Ngenxa yokuba indibaniselwano yekhoyili yokutshaya i-spark plug inokufakelwa phakathi kwe-camshaft ephezu kwe-dual overhead (DOHC), isithuba sesithuba sisetyenziswa ngokupheleleyo. Ngenxa yokucinywa komgca wosasazo kunye nombane ophezulu, ilahleko yokuqhuba amandla kunye nokulahleka kokuvuza kuncinci, akukho kutshabalala koomatshini, kwaye ikhoyili yokutshaya kunye neplagi ye-spark yesilinda nganye zidibene, kwaye iphakheji yesinyithi yangaphandle inciphisa kakhulu ukuphazamiseka kwe-electromagnetic, enokuqinisekisa ukusebenza okuqhelekileyo kwenkqubo yolawulo lwe-elektroniki yenjini.
