Isayensi yerokethi yokwenyani kwisitayile se-petrolhead.
Ngenxa yezizathu ezicacileyo (ukungabikho kweoksijini), injini yokutsha yangaphakathi ayizange isiwe esithubeni… kude kube ngoku. I-Roush Fenway Racing, iqela elibaleka kwi-NASCAR, liphuhlisa injini yokutsha eya kudibanisa imisebenzi yendawo ngenjongo enye: ukubonelela ngamandla ombane kwisistim somqhubi we-spacecraft.
Le projekthi iyinxalenye ye-IVF – i-Integrated Vehicle Fluids – inkqubo ye-United Launch Alliance, inkampani ebonelela ngeenkonzo zothutho lwemithwalo emajukujukwini. Le nkqubo ijolise ekwenzeni lula ukuhamba kweenqwelo-moya emva kokushiya i-atmosfera yoMhlaba, ukukhawulela kumafutha amabini kuphela: i-oxygen kunye ne-hydrogen. Ingxaki enkulu kukuba iinkqubo zangoku zokuqhubela phambili zisebenzisa amandla ombane amaninzi. Kulapho injini yethu endala eqhelekileyo yokutshisa ngaphakathi ingena khona.
Ukubonelela ngamandla ombane kwinkqubo, iRoush Fenway Racing ifumene isisombululo esilula kunye nentsha: isebenzisa i-injini encinci ye-cylinder emithandathu ekwaziyo ukunika ubushushu kunye nombane. Eyakhelwe ngezinto eziphezulu, le 600cc, i-26hp injini inikwe amandla okubonelela nge-oxygen ecinezelekileyo, evumela ukuba isebenze kwindawo.
Kwi-genesis yayo, le injini yokutshisa yangaphakathi njengamanye amaninzi - iintambo zokudibanisa, iiplagi ze-spark kunye nezinye izinto zivela kwi-pick-up - kodwa yaphuhliswa ukuba isebenze ixesha elide kwi-regimen enkulu ye-8,000 rpm. Umdyarho we-Roush Fenway waqala ukulinga iinjini ze-Wankel zasemoyeni (kwithiyori elula), nangona kunjalo, ibhloko ethe tye-yesithandathu yajika yaba yeyona nto ilungileyo yokuthomalalisa malunga nobunzima, ukusebenza, ukomelela kokusebenza, ukungcangcazela okuphantsi kunye nokuthambisa.
Ukongeza kokukhaphukhaphu kuneebhetri, iiseli zelanga kunye neetanki zokugcina amanzi, i-injini yokutsha inobomi obude bokusebenza kunye nokutshisa ngokukhawuleza. Okwangoku, iprojekthi ibonakala iqhuba kakuhle - sinokulinda kuphela ukufumanisa ukuba le njini incinci yokutshisa iqala nini ukungena emajukujukwini.
