Pazifukwa zodziwikiratu (kusowa kwa okosijeni), injini yoyaka mkati sinatengedwerepo mumlengalenga… mpaka pano. Gulu la Roush Fenway Racing, gulu lomwe limathamanga ku NASCAR, likupanga injini yoyatsira moto yomwe ingaphatikize mautumiki apamlengalenga ndi cholinga chimodzi: kupereka mphamvu yamagetsi panjira yoyendetsera ndege.
Ntchitoyi ndi gawo la pulogalamu ya IVF - Integrated Vehicle Fluids - ya United Launch Alliance, kampani yomwe imapereka ntchito zonyamula katundu kupita mumlengalenga. Pulojekitiyi ikufuna kupangitsa kuti magalimoto aziyenda bwino m'mlengalenga akachoka padziko lapansi, azingotsala mafuta awiri okha: oxygen ndi hydrogen. Vuto lalikulu ndilakuti makina oyendetsa magetsi akugwiritsa ntchito mphamvu zambiri zamagetsi. Ndipamene injini yathu yakale yoyatsira mkati imabwera.
Kuti apereke mphamvu zamagetsi pamakina, Roush Fenway Racing adapeza yankho losavuta komanso lachidziwitso: amagwiritsa ntchito injini yaying'ono yokhala ndi silinda sikisi yomwe imatha kupereka kutentha ndi magetsi. Yomangidwa ndi zida zapamwamba, injini iyi ya 600cc, 26hp imayendetsedwa ndi mpweya wopanikizidwa, womwe umalola kuti igwire ntchito mumlengalenga.
M'mayambiriro ake, iyi ndi injini yoyaka mkati monga zina zambiri - ndodo zogwirizanitsa, spark plugs ndi zigawo zina zimachokera ku pick-up - koma zinapangidwa kuti zigwire ntchito kwa nthawi yaitali pa ulamuliro waukulu wa 8,000 rpm. Roush Fenway Racing poyambirira adayesa injini zapamlengalenga za Wankel (mwachidziwitso chosavuta), komabe chipika chowongoka chachisanu ndi chimodzi chidakhala chogwirizana kwambiri potengera kulemera, magwiridwe antchito, kulimba kwa magwiridwe antchito, kugwedezeka pang'ono ndi mafuta.
Kuphatikiza pa kukhala opepuka kuposa mabatire, ma cell a dzuwa ndi matanki osungira madzimadzi, injini yoyaka moto imakhala ndi moyo wautali wogwiritsa ntchito komanso kuwotcha mwachangu. Pakadali pano, ntchitoyi ikuwoneka bwino - titha kudikirira kuti tidziwe nthawi yomwe injini yaying'ono yoyatsira motoyi idzayambe kulowa mumlengalenga.
