Injini m'galimoto. Chidwi. Chodabwitsa ichi chikhoza kuwononga mphamvu yamagetsi

LSPI phenomenon ndi lingaliro latsopano mumakampani amagalimoto. Ichi ndi chochokera ku kuyaka kogogoda, komwe makampani amagalimoto adathana nawo ndi chitukuko chaukadaulo wama injini oyatsira mkati omwe amayatsa spark. Chodabwitsa n'chakuti, chitukuko cha sayansi, makamaka kuchepetsa kukula, kwachititsa kuti kuyaka kwa detonation kwabwerera ku mtundu woopsa kwambiri wa zochitika za LSPI (Low-Speed ​​​​Pre-Ignition), zomwe zimamasuliridwa momasuka. , kutanthauza kuyatsa kusanachitike kutentha pang'ono.

Kumbukirani zomwe kuyaka kwa detonation kuli mu injini yoyatsira moto.

Ndi njira yoyatsira yolondola, kutangotsala pang'ono kutha kwa kuponderezana (nthawi yoyatsira), kusakaniza kwamafuta-mpweya kumayatsidwa kuchokera ku spark plug ndipo lawi lamoto limafalikira m'chipinda chonse choyaka ndi liwiro lokhazikika la 30-60 RS. Mpweya wotulutsa mpweya umapangidwa womwe umapangitsa kuti mphamvu ya silinda ikwere kupitirira 60 kgf/cm2, zomwe zimapangitsa kuti pisitoni ibwerere chammbuyo.

Mtengo wa LSPI. kuyaka kwa detonation

Mu kuyaka kogogoda, phokoso limayatsa chisakanizocho pafupi ndi spark plug, yomwe nthawi yomweyo imakanikiza otsalawo. Kuwonjezeka kwa kuthamanga ndi kuwonjezeka kwa kutentha kumayambitsa kudziwotcha ndi kuyaka mofulumira kwa osakaniza kumapeto kwa chipindacho. Ichi ndi unyolo anachita detonation, chifukwa cha chimene chiwopsezo choyaka kumawonjezeka kwambiri, kuposa 1000 m / s. Izi zimayambitsa kugogoda kwapadera, nthawi zina kulira kwachitsulo. Njira yomwe ili pamwambapa imakhala ndi mphamvu yotentha komanso yamakina pa pistoni, ma valve, ndodo zolumikizira ndi zinthu zina. Pamapeto pake, kunyalanyaza kuyaka kwa detonation kumabweretsa kufunikira kokonzanso injini yayikulu.

Kale m'zaka za m'ma XNUMX, mainjiniya adathana ndi vuto loyipali poyika sensor ya piezoelectric knock. Chifukwa cha iye, makompyuta olamulira amatha kuzindikira chodabwitsa ichi ndikusintha nthawi yoyatsira mu nthawi yeniyeni, yomwe nthawi zambiri imathetsa vutoli.

Masiku ano, komabe, chodabwitsa cha kuyaka kwamoto chikubwereranso mwanjira yowopsa kwambiri yoyatsira moto pa liwiro lotsika la injini.

Tiyeni tifufuze momwe kupita patsogolo kwaukadaulo kwapangitsa kubwereranso kwa zowopseza zodziwika bwino komanso pafupifupi kuyiwalika kumakampani amagalimoto.

Mtengo wa LSPI. Kuchepetsa

Pamodzi ndi zofunikira zachilengedwe zoperekedwa ndi mabungwe apadziko lonse lapansi, opanga magalimoto adayamba kuchepetsa mphamvu zama injini zoyatsira moto ndikugwiritsa ntchito kwambiri turbocharging. Kutulutsa kwa CO2 ndi kuyaka kwatsika kwenikweni, mphamvu ndi torque pa akavalo zawonjezeka, ndipo chikhalidwe chogwirira ntchito chakhalabe chokhutiritsa. Mosiyana ndi zomwe anthu ambiri amakhulupirira, monga chitsanzo cha injini yoyamba ya Ford ikuwonetsa, kulimba kwa injini zazing'ono kumakhalanso kofunikira. Zikuwoneka kuti pali zolakwika zambiri mu njira yothetsera vutoli.

Komabe, m'kupita kwa nthawi, nthawi zina injini zochokera kwa opanga osiyanasiyana zinayamba kuonekera zachilendo, zolakwika zazikulu za pistoni - mphete zowonongeka, mashelufu osweka, kapena ming'alu ya pistoni yonse. Vutoli, chifukwa cha kusakhazikika kwake, zakhala zovuta kuzizindikira. Chizindikiro chokhacho chomwe dalaivala amatha kuwona ndi kugogoda kosasangalatsa, kosagwirizana, mokweza kuchokera pansi pa hood yomwe imapezeka pokhapokha. Opanga magalimoto akuwunikabe vutoli, koma tikudziwa kale kuti pali zinthu zingapo zomwe zimayambitsa zochitika za LSPI.

Monga momwe zimakhalira ndi kuyaka kwanthawi yayitali, mafuta okhala ndi octane otsika kuposa momwe wopanga amapangira angakhale chimodzi mwazomwe zimayambitsa. Chinthu chachiwiri chomwe chimayambitsa kuyatsa chisanadze ndi kudzikundikira kwa mwaye m'chipinda choyaka moto. Kuthamanga kwakukulu ndi kutentha kwa silinda kumapangitsa kuti mpweya wa carbon uyambe kuyaka. China, mwina chinthu chofunikira kwambiri ndi chodabwitsa cha kutsuka filimu yamafuta pamakoma a silinda. Chifukwa cha jekeseni wamafuta mwachindunji, nkhungu ya petulo yomwe imapangidwa mu silinda imapangitsa kuti filimu yamafuta ikhale pamphuno ya pistoni. Panthawi yoponderezedwa, kuthamanga kwambiri ndi kutentha kungayambitse kudziwotcha kosalamulirika ngakhale moto usanayambike. Njirayi, yachiwawa yokhayokha, imakulitsidwanso ndi kuyatsa koyenera (kuphulika pamwamba pa silinda), zomwe zimawonjezera kupanikizika ndi chiwawa cha chochitika chonsecho.

Pambuyo pomvetsetsa momwe ndondomekoyi ikukhalira, funso limakhalapo, kodi n'zotheka kuthana ndi LSPI m'ma injini amakono, osasunthika, amphamvu kwambiri?

Mtengo wa LSPI. Kodi kukana?

Choyamba, tsatirani malangizo a wopanga kuti mugwiritse ntchito mafuta ochepa octane. Ngati wopanga akuvomereza 98 octane mafuta, ayenera kugwiritsidwa ntchito. Zosungirako zowonekera zidzalipidwa mwamsanga ndi kufunikira kwa kukonzanso mwamsanga pambuyo pa mndandanda woyamba wa zowonongeka zisanayambe. Dzazani petulo pamasiteshoni ena okha. Kugwiritsa ntchito mafuta osadziwika kumawonjezera chiwopsezo chakuti mafutawo sakhalabe ndi kuchuluka kwa octane.

Chinthu china ndikusintha kwamafuta okhazikika, osapitilira 10-15 zikwi. makilomita. Komanso, opanga mafuta asintha kale zinthu zawo pofuna kuthana ndi vuto la LSPI. Pali mafuta pamsika omwe amalonjeza kuti athana ndi vuto loyaka moto molingana ndi zomwe zanenedwa. Chifukwa cha mayeso a labotale, zidapezeka kuti kuchotsedwa kwa tinthu ta calcium m'mafuta kumathandizira izi. Kuika m'malo ndi mankhwala ena kwachepetsadi chiopsezo cha vutoli. Chifukwa chake, ngati muli ndi injini yotsika pamahatchi, mafuta odana ndi LSPI amayenera kugwiritsidwa ntchito posunga mafotokozedwe a SAE ndi API omwe amafotokozedwa ndi wopanga magalimoto.

Monga pafupifupi zolemba zonse za "malangizo agalimoto", ndimaliza ndi mawu - kupewa ndikwabwino kuposa kuchiza. Choncho, kukhala ndi injini yamphamvu yaing'ono, tcherani khutu mwapadera, wokondedwa Reader, mafuta, mafuta ndi nthawi yake m'malo.
