Injini ya Wankel idzakhala yogwirizana ndi Mazda. Unali mtundu uwu womwe wakhwima, pafupifupi, pafupifupi zaka makumi asanu zapitazi. Ndipo sabata ino amakondwerera ndendende zaka 50 kuyambira chiyambi cha malonda Mazda Cosmo Sport (110S kunja Japan), amene sanali Japanese mtundu woyamba masewera galimoto, komanso chitsanzo choyamba kugwiritsa ntchito injini rotary ndi rotors awiri.
Cosmo adafotokoza mbali yofunika kwambiri ya DNA ya mtunduwo. Iye anali wotsogolera wa zitsanzo monga mafano monga Mazda RX-7 kapena MX-5. Mazda Cosmo Sport anali roadster ndi zomangamanga tingachipeze powerenga: kutsogolo longitudinal injini ndi magudumu kumbuyo. Wankel yemwe adagwirizana ndi chitsanzo ichi anali mapasa-rotor ndi 982 cm3 ndi 110 mahatchi, omwe adakwera mpaka 130 hp ndi kukhazikitsidwa, patatha chaka chimodzi, mndandanda wachiwiri wa chitsanzo.
Mavuto a Injini ya Wankel
Zovuta zazikulu zidayenera kuthetsedwa kuti Wankel akhale womanga bwino. Kuti asonyeze kudalirika kwa teknoloji yatsopano, Mazda adaganiza zokhala nawo ndi Cosmo Sport, mu 1968, mu umodzi mwa mipikisano yovuta kwambiri ku Ulaya, maola 84 - ndikubwereza -, 84 Hours Marathon de la Route pa dera la Nürburgring.
Mwa omwe adatenga nawo gawo 58 panali awiri a Mazda Cosmo Sport, pafupifupi okhazikika, ochepera 130 mahatchi kuti alimbikitse kulimba. M'modzi wa iwo adakwanitsa mpaka kumapeto, ndikumaliza pa 4th. Winayo anatuluka pa mpikisanowo, osati chifukwa cha kulephera kwa injini, koma chifukwa cha chitsulo chimene chinawonongeka pambuyo pa maola 82 akuthamanga.
Cosmo Sport inapanga mayunitsi 1176 okha, koma zotsatira zake pa Mazda ndi injini zozungulira zinali zovuta kwambiri. Mwa opanga onse omwe adagula ziphaso ku NSU - wopanga magalimoto aku Germany ndi njinga zamoto - kuti agwiritse ntchito ndikukulitsa ukadaulo, Mazda okha adapeza bwino kugwiritsa ntchito kwake.
Unali chitsanzo ichi chomwe chinayambitsa kusintha kwa Mazda kuchokera kwa opanga magalimoto ang'onoang'ono ndi magalimoto amalonda kupita ku imodzi mwazinthu zosangalatsa kwambiri pamakampani. Ngakhale lero, Mazda amatsutsana ndi misonkhano ya engineering ndi mapangidwe, popanda kuopa kuyesa. Kaya zaukadaulo - monga zaposachedwa za SKYACTIV - kapena zogulitsa - monga MX-5, zomwe zidabwezeretsa bwino lingaliro la magalimoto ang'onoang'ono komanso otsika mtengo azaka za m'ma 60.
Tsogolo lanji la Wankel?
Mazda yapanga magalimoto pafupifupi mamiliyoni awiri okhala ndi ma Wankel powertrains. Ndipo adapanga nawo mbiri ngakhale pampikisano. Kuchokera pa kulamulira mpikisano wa IMSA ndi RX-7 (mu 1980s) mpaka kupambana kotheratu pa 24 Hours of Le Mans (1991) ndi 787B. Chitsanzo chokhala ndi ma rotor anayi, okwana malita 2.6, okhoza kupulumutsa mphamvu zoposa 700. 787B imapita m'mbiri osati chifukwa chokhala galimoto yoyamba yaku Asia kupambana mpikisano wodziwika bwino, komanso yoyamba yokhala ndi injini yozungulira kuti ikwaniritse izi.
Pambuyo pa mapeto a kupanga "Mazda RX-8" mu 2012, palibenso malingaliro a mtundu uwu wa injini mu mtundu. Kubwera kwake kwalengezedwa ndikukanidwa kangapo. Komabe, zikuwoneka kuti apa ndi pomwe mungabwerere (onani ulalo pamwambapa).
