Ithinteke kakhulu yinkinga kawoyela yango-1973, i-US yaqala iminyaka eyishumi yokufuna izixazululo ezazingeke zenze izimoto zonge nje kuphela kodwa zize ziyeke ngokuphelele uphethiloli, futhi kwakungalesi simo lapho I-Renault 12 "weqa" ne-NASA.
Imakethwa e-US, imodeli ye-Gallic yayingenye yalezo ezikhethelwe ukuba yingxenye yephrojekthi ye-NASA ye-ERDA, iphrojekthi lapho i-ejensi enesibopho sokuyisa umuntu enyangeni eminyakeni embalwa ngaphambili yayifuna ukuthola ukusebenza kahle kwezentengiselwano kwamamodeli kagesi nama-hybrid.
Kuze kube manje, i-Renault 12 "yaseNyakatho Melika" (ebonakala kalula ngenxa yezibani zayo ezimbili kanye nobhampa abakhulu) yaguqulwa yaba imodeli kagesi engu-100% yinkampani "EVA" (Electric Vehicle Associates).
Yasungulwa ngo-1974 esifundazweni sase-Ohio e-US, le nkampani yanikezelwa ekuguquleni amamodeli anezinjini ezivuthayo zibe izimoto zikagesi, ngokusekelwa uMnyango Wezamandla wase-US, njengoba sikutshelile, ufuna ukuthola ukuthi izimoto zikagesi banazo yini. "imilenze ukuhamba".
I-EVA Metro
Ngaphandle kokuthi ithuthukiswe ngokusemthethweni ngabakwaRenault, i-12 efakwe ugesi yashintsha igama layo, yaziwa ngokuthi i-EVA Metro. Ifakelwe amabhethri e-lead-acid angu-19 6-volt ngaphansi kwesivalo kanye nesiqu, i-EVA Metro yayinesisindo esingu-500 kg ngaphezu kweRenault 12, nesikalo esasinesisindo esingamakhilogremu angu-1429 ngaleso sikhathi.
Ukuze inyakaze yonke le nqwaba, i-EVA ihlomise i-12 (sorry, iMetro) ngenjini kagesi engu-13 hp eyivumela ukuthi ifinyelele isivinini esiphezulu esingu-90 km/h futhi isheshise iye ku-50 km/h ngemizuzwana engu-12. Ugearbox ubuphethe ugearbox onamagiya amathathu ozishintshayo.
Mayelana nokuzimela, kwabonisa ubuchwepheshe obukhona ngaleso sikhathi. Ngokushaja okuphelele (okuthathe cishe amahora ayisithupha endaweni engu-220V) i-EVA Metro yayikwazi ukuhamba phakathi kuka-65 no-100 km.
Futhi uma ucabanga ukuthi ukuqasha amabhethri ezimoto zikagesi zakwaRenault "kuyisicefe", kufanele wazi ukuthi amabhethri ale moto kagesi yakwaRenault 12 adinga ukwengezwa okujwayelekile kwamanzi acwecwe njengesilinganiso sokunakekela.
Izivivinyo
Obunye ubufakazi bokuziphendukela kwemvelo okungavamile kwezimoto zikagesi eminyakeni yamuva nje irekhodi lokwethembeka le-EVA Metro ekuhlolweni kweNASA (okungaboniswa ngemiphumela yayo lapha).
Kwavivinywa ngo-1975 no-1976 (enenjini entsha nesetshenzisiwe nebhethri), i-EVA Metro yaqala ukuhlaba umxhwele ekuhlolweni kokuzimela: ngesivinini esingaguquki esingu-40 km / h ihlanganisa amakhilomitha angu-91, lapho ijubane likhuphuka lafika ku-56 km. /h ukuzimela kwakhe bekuku-57 km kanti ngisho ne-speedometer imiswe ku-85 km/h ubekwazi ukugijima ku-45 km.
Ungakhohlwa ukuthi konke lokhu kwafezwa ngaphambi kwamabhethri e-lithium-ion yesimanje kanye nezinhlelo zokubhuleka ezivuselelayo. Nokho, emkhakheni wokwethembeka izinto azihambanga kahle.
Kuzo zonke, ngesikhathi sokuhlolwa kwakudingeka ukushintsha injini ye-EVA Metro izikhathi ezine. Noma kunjalo, kwakungenzeka ukubona ukuthi amabhethri e-archaic 6 volt lead-acid azokwazi ukumelana namakhilomitha angu-45,000, futhi inani elikhulu uma kubhekwa ukuthi sasiseminyakeni yawo-1970.
Ngaphandle kwebhalansi enhle yokuhlolwa, i-EVA Metro ayizange ikhiqizwe ngobuningi. Sekukonke, kwakhiqizwa amayunithi ayisikhombisa kuphela (athengiselwa abantu, izinkampani noma anikelwe emanyuvesi) futhi amabili kuphela aziwayo. Enye iseCanada kanti enye ise-US, isibuyiselwe.
