Koyatsira moto.
Ndi chitukuko cha injini ya petulo yamagalimoto kupita kumalo othamanga kwambiri, kuthamanga kwakukulu, mphamvu zambiri, kugwiritsa ntchito mafuta ochepa komanso kutulutsa mpweya wochepa, chipangizo choyatsira chachikhalidwe sichinathe kukwaniritsa zofunikira zogwiritsira ntchito.Zigawo zazikuluzikulu za chipangizo choyatsira ndi choyatsira moto ndi chosinthira, kusintha mphamvu ya koyilo yoyatsira, spark plug imatha kutulutsa mphamvu yokwanira, yomwe ndi gawo loyambira la chipangizo choyatsira kuti ligwirizane ndi magwiridwe antchito a injini zamakono. .
mfundo
Nthawi zambiri pamakhala ma seti awiri a coil mkati mwa koyilo yoyatsira, koyilo yoyamba ndi yachiwiri.Koyilo yoyamba imagwiritsa ntchito waya wandiweyani wa enamelled, kawirikawiri pafupifupi 0.5-1 mm waya wa enamelled mozungulira 200-500;Koyilo yachiwiri imagwiritsa ntchito waya wocheperako wa enamelled, nthawi zambiri waya wa enamelled wa 0.1 mm kuzungulira 15000-25000 kutembenuka.Mapeto amodzi a koyilo yoyamba amalumikizidwa ndi magetsi otsika (+) pagalimoto, ndipo mbali inayo imalumikizidwa ndi chipangizo chosinthira (chophwanya).Mapeto amodzi a koyilo yachiwiri amalumikizidwa ndi koyilo yoyamba, ndipo enawo amalumikizidwa ndi malekezero amtundu wamagetsi apamwamba kuti atulutse voteji.
Chifukwa chomwe coil yoyatsira imatha kutembenuza voteji otsika kukhala voteji yayikulu pagalimoto ndikuti ili ndi mawonekedwe ofanana ndi thiransifoma wamba, ndipo koyilo yoyambira imakhala ndi kutembenuka kwakukulu kuposa koyilo yachiwiri.Koma kuyatsa koyilo ntchito mode ndi wosiyana ndi thiransifoma wamba, thiransifoma wamba kugwira ntchito pafupipafupi 50Hz, amatchedwanso mphamvu pafupipafupi thiransifoma, ndi poyatsira koyilo ali mu mawonekedwe a kugunda ntchito, akhoza kuonedwa ngati pulse thiransifoma. molingana ndi liwiro losiyana la injini pamaulendo osiyanasiyana obwereza mphamvu zosungirako ndikutulutsa.
Koyilo yoyamba ikayatsidwa, mphamvu ya maginito imapangidwa mozungulira momwe ikukulirakulira, ndipo mphamvu ya maginito imasungidwa pakatikati pachitsulo.Chida chosinthira chikalumitsa koyilo yoyambira, mphamvu ya maginito ya koyilo yoyambayo imawola mwachangu, ndipo koyilo yachiwiri imamva mphamvu yayikulu.Kuthamanga kwa maginito a koyilo yoyamba kutha, kuwonjezereka kwamakono panthawi yomwe kutsekedwa kwamakono, ndipo kuwonjezereka kwa chiŵerengero cha ma coil awiriwo, kumapangitsa kuti magetsi apangidwe ndi koyilo yachiwiri.
Mtundu wa coil
Koyilo yoyatsira molingana ndi maginito ozungulira imagawidwa kukhala mtundu wotseguka wa maginito ndikutseka maginito amtundu wachiwiri.Koyilo yachikhalidwe yoyatsira ndi mtundu wa maginito otseguka, ndipo pachimake chake chachitsulo chodzaza ndi mapepala achitsulo a silicon 0.3mm, ndipo pali zotchingira zachiwiri ndi zoyambirira kuzungulira pachimake chitsulo.Mtundu wa maginito wotsekedwa umagwiritsa ntchito pachimake chachitsulo chofanana ndi Ⅲ kuzungulira koyilo yoyambira, kenako ndikuwomba koyilo yachiwiri kunja, ndipo mzere wa maginito umapangidwa ndi pachimake chachitsulo.Ubwino wa koyilo yotsekedwa ndi maginito ndi kutha kwa maginito, kutaya mphamvu pang'ono komanso kakulidwe kakang'ono, motero makina oyatsira amagetsi nthawi zambiri amagwiritsa ntchito koyilo yotseka yoyatsira maginito.
Nambala control poyatsira
Mu injini yamafuta othamanga kwambiri pamagalimoto amakono, njira yoyatsira yomwe imayendetsedwa ndi microprocessor, yomwe imadziwikanso kuti digito zamagetsi zamagetsi, yakhazikitsidwa.Dongosolo poyatsira lili ndi magawo atatu: ma microcomputer (kompyuta), masensa osiyanasiyana ndi ma actuators.
M'malo mwake, mu injini zamakono, jekeseni wamafuta ndi ma subsystems amawongoleredwa ndi ECU yomweyi, yomwe imagawana sensa.Sensayi imakhala yofanana ndi kachipangizo kamene kamayendetsedwa ndi magetsi, monga crankshaft position sensor, camshaft position sensor, throttle position sensor, intake multiple pressure sensor, dedetonation sensor, etc. Pakati pawo, dedetonation sensor ndi kwambiri kachipangizo odzipereka kwa magetsi ankalamulira poyatsira (makamaka injini ndi utsi mpweya turbocharging chipangizo), amene akhoza kuwunika ngati dedetonation injini ndi mlingo wa dedetonation, monga ndemanga chizindikiro kupanga ECU lamulo kukwaniritsa poyatsira pasadakhale, kuti injini sichidzasokoneza ndipo imatha kupeza kuyaka bwino kwambiri.
Digital electronic ignition system (ESA) imagawidwa m'mitundu iwiri molingana ndi kapangidwe kake: mtundu wa distributor ndi non-distributor type (DLI).Makina oyatsira amtundu wamagetsi amagwiritsa ntchito koyilo imodzi yokha yoyatsira kuti apange voteji yayikulu, ndiyeno wogawayo amayatsa spark plug ya silinda iliyonse motsatana ndi njira yoyatsira.Popeza ntchito yozimitsa ya coil yoyamba ya coil yoyatsira imachitika ndi dera loyatsira pamagetsi, wogawayo waletsa chipangizo chophwanyira ndipo amangosewera ntchito yogawa kwambiri.
Kuyatsa kwamitundu iwiri
Kuyatsa kwa ma silinda awiri kumatanthauza kuti ma silinda awiri amagawana coil imodzi yoyatsira, motero kuyatsa kwamtunduwu kungagwiritsidwe ntchito pa injini zokhala ndi ma silinda angapo.Ngati pa makina a 4-cylinder, pamene ma pistoni awiri a cylinder ali pafupi ndi TDC panthawi imodzimodzi (imodzi ndi yoponderezedwa ndipo ina ikutha), mapulagi awiri amagawana coil yoyatsira imodzimodzi ndikuyaka nthawi imodzi, ndiye kuti imodzi ndi yothandiza. poyatsira ndipo winayo ndi wosagwira ntchito poyatsira, choyambiriracho chimakhala chosakanikirana ndi kuthamanga kwambiri ndi kutentha kochepa, chotsiriziracho chiri mu mpweya wotulutsa mpweya wochepa komanso kutentha kwakukulu.Choncho, kukana pakati pa spark plug maelekitirodi awiriwa ndi osiyana kwambiri, ndipo mphamvu yopangidwa si yofanana, zomwe zimapangitsa kuti pakhale mphamvu yowonjezereka yoyatsira mogwira mtima, yomwe imawerengera pafupifupi 80% ya mphamvu zonse.
Kuyatsa kosiyana
Njira yoyatsira yosiyana imagawira koyilo yoyatsira pa silinda iliyonse, ndipo coil yoyatsira imayikidwa mwachindunji pamwamba pa spark plug, yomwe imachotsanso waya wokwera kwambiri.Njira yoyatsira iyi imatheka ndi sensa ya camshaft kapena kuyang'anira kuponderezedwa kwa silinda kuti ikwaniritse kuyatsa kolondola, ndikoyenera kwa injini zamasilinda angapo, makamaka ma injini okhala ndi ma valve 4 pa silinda.Chifukwa chophatikizira cha spark plug ignition coil chitha kukhazikitsidwa pakati pa camshaft yapawiri yapawiri (DOHC), malo ocheperako amagwiritsidwa ntchito mokwanira.Chifukwa cha kuthetsedwa kwa wogawa ndi mzere wamagetsi okwera kwambiri, kutayika kwamagetsi ndi kutayika kwa kutayikira kumakhala kochepa, palibe kuvala kwamakina, ndipo coil yoyatsira ndi spark plug ya silinda iliyonse imasonkhanitsidwa palimodzi, ndipo phukusi lakunja lachitsulo limachepetsa kwambiri kusokonezedwa kwa ma elekitiroma, komwe kumatha kuwonetsetsa kuti injini yoyang'anira zamagetsi ikugwira ntchito bwino.
Chonde tiyimbireni ngati mukufuna such mankhwala.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zolandiridwa kuti mugule.
