I-Rotary ngaphambi kwe-Mazda RX-7: I-Nissan, i-Chevrolet, i-Mercedes-Benz nezinye izinhlobo ezazinezinhlelo ezinhle ze-Rotary

I-Mazda RX-7 yenza injini ye-rotary yaduma ngo-1978.

Manje sekuwumlando ukuthi ukubekezela kweMazda ngenjini ejikijelwa yi-rotary sekuyiphendule iyunithi ethokozisayo nethembekile esizoba yintandokazi kubanikazi abaningi abanomdlandla.

Endleleni, lo mqondo ubuye wafakazela amandla awo okunqoba i-Mazda's 24 Hours of Le Mans ngo-1991, umsebenzi okungekho omunye umkhiqizi waseJapane ongakwazi ukuwenza cishe iminyaka engamashumi amathathu.

Kodwa njengamanoveli amaningi, inoveli ye-Wankel inesabelo sayo esifanele sobudlelwane obunesiyaluyalu kanye nomkhondo wesiginesha wosizi lwenhliziyo.

Abanye uzobe ubazi, abanye hhayi kangako ...

Iningi lezimoto ezibalwe lapha azikaze zikhishwe. Futhi nakulabo abakwenzile lokho, ukomela uphethiloli nokungathembeki kwesikhungo sikagesi sakwa-Wankel kwakuyizici eziyinhloko ekushoneni kwabo.

Kodwa bonke babelane ngephupho lezinjini ezijikelezayo, futhi bonke bandulele umshini owagcina uxazulule izinkinga futhi empeleni wanikeza amaphiko ajikelezayo; yasekuqaleni 7 Mazda RX-1978.

I-Citroen Bureau

Phakathi kuka-1973 no-1975, i-Citroën yafaka imodeli enamandla e-rotary ekukhiqizeni.

Yayibizwa nge-Birotor futhi empeleni yayiyi-GS enenjini ye-Wankel enamagumbi amabili ngaphansi kwe-hood.

Ziningana izinto ezidlale ngokumelene ne-GS Birotor, ziqala ngokuthi kwakubiza ukuyikhiqiza futhi ngenxa yalokho yafika emakethe ngentengo ecishe ilingane naleyo yohlobo lwe-Citroen DS enkulu futhi ewubukhazikhazi.

ICitroen iphinde yabambelela ku-twitchy, clunky three-speed semi-automatic transmission, kanti ijubane eliphezulu belijwayelekile ukuthi libe ngu-170 km/h, ijubane lifike ku-100 km/h ngemizuzwana engu-14.

Okwenza izinto zibe zimbi nakakhulu, ukusetshenziswa kukaphethiloli kwakubi kakhulu - abanye bathi kufika ku-20 l / 100 km - lokho ezwekazini laseYurophu kwakungeke kwenzeke.

Ngisho nangaphambi kwe-Birotor, ngo-1971, i-Citroen yayivele izama izinjini ezijikelezayo.

Wakha i-prototype i-M35 esebenzisa umzimba we-Ami 8 oguqulelwe ekubeni yi-coupe futhi enikwa amandla yinjini efanayo yamawele we-Wankel.

Ayizange ifakwe ekukhiqizeni, mhlawumbe ngenxa yokuthi yayibukeka njengesiteyi sokubamba imoto yangempela.

I-AMC Pacer

Khumbula imoto exakile efana ne-aquarium u-Wayne no-Garth abayigibele ngesikhathi bezamazama e-Bohemian Rhapsody Umhlaba kaWayne?

Le moto bekuyi-AMC Pacer futhi yaklanywa kusukela ekuqaleni inomzimba omusha (owase-US) we-hatchback kanye ne-rotary powerplant.

Naphezu kokubukeka kwayo okudwetshiwe, i-Pacer yayiklanyelwe ukulinga abantu baseMelika abathanda izimoto ezinkulu ukuthi benze okuthile okuhlangene nokusebenza kahle.

I-Pacer yayimfushane ngokugcwele ngamamitha angu-1.4 kuneCadillac, kodwa yayibanzi ngo-50 mm, okuyenza icishe ibe isikwele.

Uhlelo lwe-rotary lubhuntshile ngesikhathi kuvela ukuthi injini (i-AMC eyayihlele ukuyithenga kwaGeneral Motors) yayingase ingathembeki futhi iphelelwe amandla.

Esikhundleni salokho, isitokwe i-1975 Pacer sasinikwa amandla injini enkulu engaphakathi kwe-inline-six eyayinkulu kakhulu ngokomzimba (futhi yafakwa ngaphansi kwe-windshield ngenxa yalokho, okwenza ukufinyelela kwesevisi kube nzima), kuyilapho isitsha sesaladi esihlanekeziwe sibukeka sengathi sesifikile. amagumbi ombukiso.

Bese ukukhetha okungokwemvelo kukaWayne noGarth.

I-Trio General Motors

Ngawo-1970, i-GM yayiyizinjini ezijikelezayo kakhulu.

Yayinomklamo olungele ukukhiqiza futhi inesibindi.

Nakuba izinjini eziningi zezimoto ezijikelezayo zisukela kumalitha owodwa kuye ku-1.3, injini ye-GM enemigqomo emibili yayiwumthamo omkhulu wamalitha angu-3.3, okuphakamisa ukuthi ingashayela njengesihogo futhi iphuze njengesikebhe esikhulu.

Ekugcineni, izinto zaba nzima kakhulu, futhi ukuhlolwa kwaqinisekisa ukonga kukaphethiloli ngendlela eshaqisayo kanye nokuthambekela okubi kokuzilimaza. Ngamanye amazwi, izinto ezijwayelekile zakuqala ezijikelezayo.

Futhi ngokushabalala kwe-RC2-206 (njengoba injini yayibizwa kanjalo), ayengasekho amathemba okukhethwa kwenjini ejikelezayo ye-Chevrolet Vega, i-2+2 rotary Monza, ngisho nenguqulo ejikelezayo ehleliwe yalesi sisekelo sokugcina sezinjini ze-piston. . amandla, Corvette.

IMercedes-Benz C111

Uma ucabanga ngempela ngakho, i-Benz C111's gullwing doors yayenza yagqama ngaleso sikhathi (1969) njengohlobo lomlandeli we-300SL yodumo yama-1950s.

Kodwa-ke, imoto yakamuva yayiwumbhede wokuhlola ubuchwepheshe, okuhlanganisa umzimba we-fiberglass, i-turbocharging, i-multi-link suspension, futhi-ke, injini ye-rotary enamagumbi amathathu efakwe ngemuva kwezihlalo.

I-Benz ibone kusenesikhathi ukuthi uma iqhathaniswa namanani ayisisekelo omkhiqizo, injini ejikelezayo yayiyindawo yokucasha kwezobuchwepheshe, ngakho-ke yizibonelo zesizukulwane sokuqala se-C111 kuphela ezazinalolu lungiselelo.

Kamuva izimoto zasebenzisa izinjini zikaphethiloli eziyi-V8, kodwa ngisho nakulolu hlobo oluhlanjululwe, imoto ayizange ingene ekukhiqizeni.

Kodwa-ke, i-C111 esebenzisa udizili yabeka amarekhodi amaningi esivinini ngo-1978, okuhlanganisa nophawu lwemilingo luka-200 mph.

Datsun Sunny RE

Nakuba i-Mazda kuwuphawu lwaseJapane oluhlotshaniswa kakhulu nenjini ye-Wankel rotary, i-Nissan (eyayiyi-Datsun ngaleso sikhathi) nayo yehla.

I-Datsun yaqala ukuhlola umqondo we-rotary ngeminyaka yawo-60, kwathi ngo-1972, kwaboniswa i-rotary-powered coupe prototype embukisweni wezimoto i-Tokyo Motor Show.

Ngokusekelwe ku-Datsun 1200 ejwayelekile, i-RE isebenzisa ilitha elilodwa, injini ejikelezayo eyimiphongolo emibili. Lezi zinhlelo bezihlanganisa ibhukwana elinamagiya amahlanu kanye ne-automatic version enamagiya amathathu.

Kodwa njengawo wonke umuntu ngaphandle kwe-Mazda, i-Datsun yaxoshwa ukwethembeka kanye nezindaba zokusetshenziswa kukaphethiloli ekwakhiweni kwenjini engaphansi, futhi i-1200RE ayizange ifakwe ekukhiqizeni.

Uma kucatshangelwa ukuthi kungaguqula okujabulisayo okungu-1200 kube ugibe lokufa ku-175 mph, mhlawumbe lokho kungcono kakhulu.

Upelepele 2101

Akwaziwa kahle ngokuthambekela kwabo ukulandela izitayela zomhlaba, amaRussia, nokho, nawo athinte injini ejikelezayo.

Kusukela ngomklamo owodwa we-rotor ngo-1974, amaRussia agcina akhe inguqulo engama-twin rotor eyathuthukisa amandla amahhashi angaphezu kuka-100 futhi yaqhubeka nokukhiqizwa kuze kube yiminyaka yawo-1980.

Njengezinto eziningi zaseRussia, i-VAZ 311 (njengoba injini yayibizwa kanjalo) yayidakiwe futhi idinga ukulungiswa njalo, kodwa i-twin-rotor "Lada" yayicishe ibe ngokushesha njengedrayivu yamasondo amane e-Cold War USSR.

Mhlawumbe akumangalisi ukuthi umlandeli omkhulu we-Rotary Lada kwakuyi-KGB, futhi uLada waze wakha izinguqulo ezikhethekile zemoto ukuze nje amaphoyisa ayimfihlo adlale "isivakashi esimangalisayo."

I-NSU Spider

Nakuba sonke sazi i-NSU Ro80 njengemoto eyabulala i-marque (noma kunalokho, yaphoqa ukuthi ihlangane ne-Audi) ngenxa yenkinga yenjini ye-Wankel kanye nezimangalo zewaranti eyalandela, i-Ro80 empeleni kwakungeyona imoto yokuqala yokukhiqiza ye-NSU, kukhona injini.

Lokho kuhlonishwa kuya ku-1964 NSU Spider, eyayisekelwe ku-NSU Prinz eguqulekayo eyethulwa okokuqala ngo-1959.

Injini ye-Rotary yegumbi elilodwa eno-498 cc kuphela cm, kodwa yayinamandla ngokwanele ukwenza imoto ehlekisayo nethi yezemidlalo ngeSpider esincane.

Isakhiwo esinenjini yangemuva sibolekwe kuPrinz futhi, njengale moto, isitayela se-brash sasiwumsebenzi kaBertone.

I-NSU yakha ama-Spider angaphansi kuka-2400, kodwa ukube yakhiwe ngamavolumu e-Ro80 (amayunithi angaphezu kuka-37,000 eminyakeni eyishumi yokukhiqiza), cishe yayizoyiqeda inkampani ngokwayo, ngakho-ke izinkinga zenjini ezijikelezayo ngaleso sikhathi.
