Kuyendetsa MultiAir kumachepetsa kugwiritsa ntchito mafuta ndi 25%
Fiat yatulutsa tekinoloje yomwe, kudzera pamagetsi oyendetsera valavu iliyonse, imachepetsa kugwiritsa ntchito mafuta ndi mpweya mpaka 25%. Choyamba chake chikuyenera chaka chino ku Alfa Mito.
Njira imeneyi imachotsera camshaft wamba wamagalimoto okhala ndi mavavu anayi pa silinda iliyonse. Imalowetsedwa m'malo ndi magetsi oyendetsa magetsi.
Kugwiritsa ntchito 25% kocheperako komanso mphamvu zowonjezera 10%
Ubwino ndikuti ma valve oyamwa amayendetsedwa mosadalira crankshaft. M'dongosolo la MultiAir, mavavu oyamwa amatha kutsegulidwa ndikutseka nthawi iliyonse. Chifukwa chake, kudzazidwa kwa silinda kumatha kusinthidwa nthawi iliyonse mpaka katundu wagawo. Izi zimalola kuti injini igwire bwino ntchito mulimonse momwe zingakhalire.
Kuphatikiza pakuchepetsa kwakukulu kwamafuta ndi mpweya, Fiat imalonjezanso kuwonjezeka kwa 15% kwa torque mumayendedwe otsika a rpm, komanso kuyankha mwachangu kwa injini. Malingana ndi kampaniyo, kuwonjezeka kwa mphamvu kumafika 10%. Kuphatikiza apo, pa injini yozizira, mpweya wa nitrous oxide uyenera kuchepetsedwa mpaka 60%, makamaka mpweya woipa wa monoxide ndi 40%.
Fiat ikufuna kugwiritsa ntchito ukadaulo wa MultiAir mu injini zonse zachilengedwe komanso zotulutsa turbocharged. Kuphatikiza apo, injini za dizilo ziyeneranso kupindula ndi izi.
Mipikisano ya MultiAir mu Alfa Romeo Mito
Alfa Romeo Mito watsopano azikhala ndi ukadaulo wa MultiAir mkatikati mwa chaka chino. Ipezeka ndi injini yamafuta okwana lita imodzi yopezeka mwachilengedwe komanso mtundu wa turbocharged. Kuphatikiza apo, Fiat yalengeza injini yatsopano yama 1,4cc yama cylinder awiri yamphamvu. Onani ndi ukadaulo wa MultiAir.
Injiniyi idzasinthidwa kuti igwiritse ntchito mafuta ndi gasi wachilengedwe (CNG), ndipo ipangidwanso mumlengalenga komanso mumtunda wa turbo. Malinga ndi nkhawa, mpweya wake wa CO2 ukhala pansi pa magalamu 80 pa kilomita.
Ma injini a dizilo nawonso azikhala ndi makina a MultiAir.
Fiat ikukonzekera kugwiritsa ntchito ukadaulo wa MultiAir pamainjini ake a dizilo mtsogolo. Amachepetsanso kwambiri mpweya pakuwongolera bwino ndikusinthira fyuluta ya tinthu.
