Injini yakwaWankel iyakuhlala idityaniswa neMazda. Yayiluphawu oluye lwakhula, phantse ngokukhethekileyo, kule minyaka ingamashumi amahlanu idlulileyo. Kwaye le veki ibhiyozela kanye iminyaka engama-50 ukususela ekuqaleni ukuthengiswa Mazda Cosmo Sport (110S ngaphandle Japan), nto leyo yayingeyona nje imoto ezemidlalo Japanese brand yokuqala, kodwa imodeli yokuqala ukusebenzisa injini rotary kunye rotors ezimbini.
I-Cosmo yeza ukuchaza inxalenye ebalulekileyo ye-DNA ye-brand. Wayengumanduleli weemodeli ezinomfanekiso njengeMazda RX-7 okanye iMX-5. I-Mazda Cosmo Sport yayiyi-roadster ene-architecture yakudala: i-injini ye-longitudinal yangaphambili kunye ne-wheel drive yangasemva. I-Wankel eyayifake le modeli yayiyi-rotor ye-twin kunye ne-982 cm3 kunye ne-110 horsepower, eyanyuka yaya kwi-130 hp kunye nokuqaliswa, emva konyaka, kochungechunge lwesibini lwemodeli.
Imingeni ye-injini yeWankel
Imiceli mngeni emikhulu kwafuneka yoyiswe ukwenza i-Wankel ibe yi-architecture esebenzayo. Ukubonisa ukuthembeka kobuchwephesha obutsha, uMazda wagqiba ekubeni athathe inxaxheba kunye neCosmo Sport, ngo-1968, kwenye yezona ntlanga zinzima eYurophu, iiyure ezingama-84 - ndiyaphinda-, Iiyure ezingama-84 iMarathon de la Route kwisekethe yaseNürburgring.
Phakathi kwabathathi-nxaxheba abangama-58 kukho iMazda Cosmo Sport ezimbini, ezisemgangathweni, zilinganiselwe kumandla amahashe angama-130 ukomeleza ukuqina. Omnye wabo uye wafikelela esiphelweni, ephuma kwindawo yesi-4. Omnye urhoxile elugqatsweni, hayi ngenxa yokusilela kwenjini, kodwa ngenxa yokonakala kweasi emva kweeyure ezingama-82 elugqatsweni.
I-Cosmo Sport inemveliso yeeyunithi ezili-1176 kuphela, kodwa impembelelo yayo kwi-Mazda kunye neenjini ezijikelezayo zazibalulekile. Kubo bonke abavelisi abathenge iilayisensi kwi-NSU – inkampani yaseJamani eyenza iimoto nezithuthuthu – ukusebenzisa nokuphuhlisa obu buchwepheshe, yiMazda kuphela efumene impumelelo ekusebenziseni kwayo.
Yaba lo mzekelo owaqalisa inguqu yeMazda ukusuka kumenzi oqhelekileyo weemoto ezincinci kunye neenqwelo zorhwebo ukuya kwezona mpawu zinika umdla kweli shishini. Nanamhla oku, iMazda iyazichasa iindibano zobunjineli kunye noyilo, ngaphandle koloyiko lokuzama. Nokuba itekhnoloji - ezifana SKYACTIV yamva nje - okanye iimveliso - ezifana MX-5, leyo ngempumelelo waphinda wafumana ingqiqo sportscars ezincinane kwaye ezifikelelekayo ka 60.
Liliphi ikamva likaWankel?
IMazda yenze malunga nezigidi ezibini zeemoto ezixhotyiswe ngeWankel powertrains. Kwaye wenza imbali nabo nakukhuphiswano. Ukusuka ekulawuleni ubuntshatsheli be-IMSA nge-RX-7 (ngoo-1980) ukuya kuloyiso olupheleleyo kwiiyure ezingama-24 zeLe Mans (1991) kunye ne-787B. Imodeli exhotyiswe ngee-rotors ezine, i-2.6 yelitha iyonke, ekwazi ukuhambisa ngaphezu kwe-700 yamahashe. I-787B yehla kwimbali kungekuphela nje ngokuba yimoto yokuqala yaseAsia ukuphumelela ugqatso oludumileyo, kodwa neyokuqala ixhotyiswe nge-injini ejikelezayo ukufezekisa loo nto.
Emva kokuphela kokuveliswa kweMazda RX-8 ngo-2012, akusekho naziphi na izindululo zolu hlobo lwenjini kwi-brand. Ukubuya kwakhe kuye kwabhengezwa kwaye kwaliwa amaxesha amaninzi. Nangona kunjalo, kubonakala ngathi kulapho unokubuyela khona (jonga ikhonkco elingasentla).
