Injini yakwaWankel izohlotshaniswa neMazda kuze kube phakade. Kwakuyilolu hlobo olukhule, cishe ngokukhethekile, phakathi neminyaka engamashumi amahlanu edlule. Futhi kuleli sonto igubha ncamashi iminyaka engu-50 kusukela ekuqaleni ukumaketha "Mazda Cosmo Sport" (110S ngaphandle Japan), okwakungeyona nje imoto yokuqala yezemidlalo Japanese brand, kodwa futhi imodeli yokuqala ukusebenzisa injini rotary nge rotors ezimbili.
U-Cosmo weza ukuzochaza ingxenye ebalulekile ye-DNA yomkhiqizo. Ube ngumanduleli wamamodeli anjenge-Mazda RX-7 noma i-MX-5. I-Mazda Cosmo Sport yayiyi-roadster enezakhiwo zakudala: injini yobude bangaphambili kanye nokushayela ngamasondo angemuva. I-Wankel efake le modeli bekuyi-twin-rotor eno-982 cm3 enamandla amahhashi angu-110, ekhuphuke yafinyelela ku-130 hp lapho kwethulwa, ngemva konyaka, kochungechunge lwesibili lwale modeli.
I-Wankel Engine Challenges
Izinselelo ezinkulu bekufanele zinqotshwe ukuze kwenziwe i-Wankel i-architecture esebenzayo. Ukukhombisa ukwethembeka kobuchwepheshe obusha, iMazda yanquma ukubamba iqhaza neCosmo Sport, ngo-1968, komunye wemijaho enzima kakhulu eYurophu, amahora angama-84 - ngiyaphinda -, 84 Hours Marathon de la Route kusekethe yaseNürburgring.
Phakathi kwabahlanganyeli abangu-58 bekukhona iMazda Cosmo Sport emibili, ejwayelekile, elinganiselwe kumandla amahhashi angu-130 ukuqinisa ukuqina. Omunye wabo ufinyelele ekugcineni, waqeda endaweni yesi-4. Omunye uhoxile emjahweni, hhayi ngenxa yokwehluleka kwenjini, kodwa ngenxa yokulimala kwe-asi ngemva kwamahora angu-82 kulo mjaho.
ICosmo Sport ikhiqize amayunithi angu-1176 kuphela, kodwa umthelela wayo kuMazda nezinjini ezijikelezayo wawubalulekile. Kubo bonke abakhiqizi abathenge amalayisensi kwa-NSU - inkampani yaseJalimane ekhiqiza izimoto nezithuthuthu - ukusebenzisa nokuthuthukisa ubuchwepheshe, yiMazda kuphela eyathola impumelelo ekusebenziseni kwayo.
Yilolu hlobo olwaqala ukuguquka kweMazda isuka ekubeni ngumkhiqizi ojwayelekile wezimoto ezincane kanye nezimoto zezentengiselwano yaba enye yezinhlobo ezijabulisa kakhulu embonini. Ngisho nanamuhla, i-Mazda iphikisana nezivumelwano zobunjiniyela nokuklama, ngaphandle kokwesaba ukuhlola. Kungakhathaliseki ukuthi okobuchwepheshe - njenge-SKYACTIV yakamuva - noma imikhiqizo - efana ne-MX-5, ebuyise ngempumelelo umqondo wezimoto zemidlalo ezincane nezithengekayo zama-60's.
Liyini ikusasa likaWankel?
IMazda isikhiqize izimoto ezibalelwa ezigidini ezimbili ezihlome ngeWankel powertrains. Futhi uqophe umlando nabo ngisho emqhudelwaneni. Ukusuka ekuphatheni umqhudelwano we-IMSA nge-RX-7 (ngawo-1980s) kuya ekunqobeni okuphelele kuma-24 Hours of Le Mans (1991) nge-787B. Imodeli efakwe ama-rotor amane, afinyelela ku-2.6 litres, ekwazi ukuletha amandla angaphezu kuka-700 amahhashi. I-787B yehlela emlandweni hhayi nje ngokuba imoto yokuqala yase-Asia ukuwina umjaho odumile, kodwa futhi neyokuqala efakwe injini ye-rotary ukufeza lokho.
Ngemva kokuphela kokukhiqizwa kwe-Mazda RX-8 ngo-2012, azisekho iziphakamiso zalolu hlobo lwenjini kumkhiqizo. Ukubuya kwakhe kumenyezelwe futhi kwanqatshwa izikhathi eziningi. Nokho, kubonakala sengathi kulapho ongabuyela khona (bheka isixhumanisi ngenhla).
