Choyikira moto.
Popeza injini ya petulo yamagalimoto yapangidwa kuti igwirizane ndi liwiro lalikulu, kupanikizika kwakukulu, mphamvu zambiri, kugwiritsa ntchito mafuta ochepa komanso kutulutsa mpweya wochepa, chipangizo choyatsira moto chachikhalidwe sichinathe kukwaniritsa zofunikira pakugwiritsa ntchito. Zigawo zazikulu za chipangizo choyatsira moto ndi choyatsira moto ndi chipangizo chosinthira, zomwe zimapangitsa kuti mphamvu ya choyatsira moto iwonjezeke, pulagi ya spark plug ipange mphamvu zokwanira, zomwe ndi zofunika kwambiri pa chipangizo choyatsira moto kuti chigwirizane ndi magwiridwe antchito a injini zamakono.
mfundo
Nthawi zambiri pamakhala ma coil awiri mkati mwa coil yoyatsira moto, coil yoyamba ndi coil yachiwiri. Coil yoyamba imagwiritsa ntchito waya wokhuthala wa enamelled, nthawi zambiri waya wokhuthala wa 0.5-1 mm pafupifupi kuzungulira 200-500; Coil yachiwiri imagwiritsa ntchito waya woonda wa enamelled, nthawi zambiri waya wokhuthala wa 0.1 mm pafupifupi kuzungulira 15000-25000. Malekezero amodzi a coil yoyamba amalumikizidwa ku magetsi otsika (+) pagalimoto, ndipo malekezero ena amalumikizidwa ku chipangizo chosinthira (chosweka). Malekezero amodzi a coil yachiwiri amalumikizidwa ndi coil yoyamba, ndipo malekezero ena amalumikizidwa ndi malekezero otuluka a mzere wamagetsi apamwamba kuti atulutse magetsi okwera.
Chifukwa chomwe choyatsira moto chimatha kusintha magetsi otsika kukhala magetsi okwera pagalimoto ndichakuti chimakhala ndi mawonekedwe ofanana ndi choyatsira moto wamba, ndipo choyatsira moto chachikulu chimakhala ndi chiŵerengero chachikulu chozungulira kuposa choyatsira moto chachiwiri. Koma njira yogwirira ntchito yoyatsira moto ndi yosiyana ndi choyatsira moto wamba, ma frequency ogwirira ntchito a transformer wamba ndi okhazikika 50Hz, omwe amadziwikanso kuti mphamvu yosinthira ma frequency, ndipo choyatsira moto chili mu mawonekedwe a ntchito ya pulse, chimatha kuonedwa ngati choyatsira moto, malinga ndi liwiro losiyana la injini pama frequency osiyanasiyana osungira mphamvu mobwerezabwereza komanso kutulutsa mphamvu.
Pamene coil yoyamba ikuyendetsedwa, mphamvu yamphamvu ya maginito imapangidwa mozungulira pamene mphamvu ya magetsi ikuwonjezeka, ndipo mphamvu ya mphamvu ya maginito imasungidwa mu chitsulo. Chipangizo chosinthira chikachotsa dera la coil yoyamba, mphamvu ya maginito ya coil yoyamba imawonongeka mofulumira, ndipo coil yachiwiri imamva mphamvu yamagetsi yapamwamba. Mphamvu ya maginito ya coil yoyamba ikatha mofulumira, mphamvu yamagetsi yamagetsi ikachepa kwambiri panthawi yolekanitsidwa kwa mphamvu yamagetsi, ndipo chiŵerengero cha maginito awiriwa chikakula, mphamvu yamagetsi yomwe imayambitsa coil yachiwiri imakwera kwambiri.
Mtundu wa koyilo
Choyikira choyatsira malinga ndi dera la maginito chimagawidwa m'magulu awiri: mtundu wa maginito otseguka ndi mtundu wachiwiri wa maginito otsekedwa. Choyikira choyatsira chachikhalidwe ndi mtundu wa maginito otseguka, ndipo pakati pake pachitsulo pali mapepala achitsulo a silicon a 0.3mm, ndipo pali ma coil achiwiri ndi oyamba kuzungulira pakati pachitsulo. Mtundu wa maginito wotsekedwa umagwiritsa ntchito pakati pachitsulo chofanana ndi Ⅲ kuzungulira choyikira choyamba, kenako n’kuzungulira choyikira chachiwiri kunja, ndipo mzere wa maginito umapangidwa ndi pakati pachitsulo. Ubwino wa choyikira choyatsira cha maginito chotsekedwa ndi kuchepa kwa kutayikira kwa maginito, kutayika pang'ono kwa mphamvu ndi kukula kochepa, kotero makina oyatsira amagetsi nthawi zambiri amagwiritsa ntchito choyikira choyatsira cha maginito chotsekedwa.
Kuyatsa kwa manambala
Mu injini ya petulo yothamanga kwambiri yamagalimoto amakono, makina oyatsira moto omwe amayendetsedwa ndi microprocessor, omwe amadziwikanso kuti makina oyatsira magetsi a digito, agwiritsidwa ntchito. Makina oyatsira moto ali ndi magawo atatu: kompyuta yaying'ono (kompyuta), masensa osiyanasiyana ndi ma actuator oyatsira moto.
Ndipotu, m'mainjini amakono, njira zoyatsira mafuta ndi kuyatsa moto zimayendetsedwa ndi ECU yomweyo, yomwe imagawana masensa. Sensa imakhala yofanana ndi sensa yomwe ili mu dongosolo loyatsira mafuta lolamulidwa ndi magetsi, monga sensa ya malo a crankshaft, sensa ya malo a camshaft, sensa ya malo a throttle, sensa ya kuthamanga kwa intake manifold, sensa ya dedetonation, ndi zina zotero. Pakati pawo, sensa ya dedetonation ndi sensa yofunika kwambiri yodzipereka ku kuyatsa moto kolamulidwa ndi magetsi (makamaka injini yokhala ndi chipangizo cha turbocharging cha gasi wotulutsa utsi), yomwe imatha kuyang'anira ngati kuchotsedwa kwa injini ndi kuchuluka kwa kuchotsedwa kwa moto, ngati chizindikiro chobwezera kuti ECU ilamulire kuyatsa moto pasadakhale, kuti injini isachotsedwe ndipo ipeze mphamvu yoyaka kwambiri.
Dongosolo lamagetsi loyatsira magetsi la digito (ESA) limagawidwa m'magulu awiri malinga ndi kapangidwe kake: mtundu wa wogawa ndi mtundu wosagawa (DLI). Dongosolo lamagetsi loyatsira magetsi la mtundu wa wogawa limagwiritsa ntchito koyilo imodzi yokha yoyatsira magetsi kuti ipange magetsi ambiri, kenako wogawa amayatsa pulagi ya silinda iliyonse motsatizana malinga ndi momwe magetsi amayatsira. Popeza ntchito yoyatsira magetsi ya koyilo yoyamba ya koyilo yoyatsira magetsi imachitikira ndi dera loyatsira magetsi lamagetsi, wogawa magetsi waletsa chipangizo choyatsira magetsi ndipo amangogwira ntchito yogawa magetsi amphamvu.
Kuyatsa kwa masilinda awiri
Kuyatsa kwa masilinda awiri kumatanthauza kuti masilinda awiri amagawana coil imodzi yoyatsira moto, kotero mtundu uwu wa kuyatsa moto ungagwiritsidwe ntchito pa injini zokhala ndi masilinda ofanana. Ngati pa makina a masilinda anayi, pamene ma pistoni awiri a masilinda ali pafupi ndi TDC nthawi imodzi (imodzi ndi yokakamiza ndipo inayo ndi yotulutsa utsi), ma spark plug awiri amagawana coil yoyatsira moto yomweyo ndipo amayatsa nthawi imodzi, ndiye kuti imodzi ndi yoyatsira moto yogwira ntchito ndipo inayo ndi yoyatsira moto yogwira ntchito, yoyamba ili mu chisakanizo cha kuthamanga kwambiri ndi kutentha kochepa, yachiwiri ili mu mpweya wotulutsa utsi wa kuthamanga kochepa ndi kutentha kwakukulu. Chifukwa chake, kukana pakati pa ma electrode a spark plug a awiriwa ndi kosiyana kwambiri, ndipo mphamvu zomwe zimapangidwa sizofanana, zomwe zimapangitsa kuti pakhale mphamvu yayikulu kwambiri yoyatsira moto yogwira ntchito, yomwe imapanga pafupifupi 80% ya mphamvu yonse.
Kuyatsa kosiyana
Njira yosiyanitsira yosiyana imagawa choyikira choyatsira moto pa silinda iliyonse, ndipo choyikiracho chimayikidwa mwachindunji pamwamba pa choyikira choyatsira moto, chomwe chimachotsanso waya wamagetsi ambiri. Njira yoyatsira moto iyi imachitika ndi sensa ya camshaft kapena poyang'anira kupsinjika kwa silinda kuti ikwaniritse kuyatsa kolondola, ndiyoyenera injini za silinda zingapo, makamaka injini zokhala ndi ma valve anayi pa silinda iliyonse. Chifukwa kuphatikiza kwa choyikira choyatsira moto kumatha kuyikidwa pakati pa camshaft yozungulira iwiri (DOHC), malo otseguka amagwiritsidwa ntchito mokwanira. Chifukwa cha kuletsa kwa mzere wogawa ndi wamagetsi ambiri, kutayika kwa mphamvu ndi kutayika kwa kutayikira kwa magetsi kumakhala kochepa, palibe kuwonongeka kwa makina, ndipo choyikira choyatsira moto ndi choyikira choyatsira moto cha silinda iliyonse zimasonkhanitsidwa pamodzi, ndipo phukusi lachitsulo lakunja limachepetsa kwambiri kusokoneza kwa maginito, komwe kungatsimikizire kuti makina owongolera zamagetsi a injini amagwira ntchito bwino.
