Pfupisa nyaya yacho:  Audi yakagadzira chinonzi 'green' chinotyaira mafuta chinogadzirwa nokushandisa musanganiswa wemvura necarbon dioxide. Mugadziri wemotokari akarondedzera kubudirira kwake se'mafuta emangwana' uye anotaura kuti aigona kugovera nzira isina kabhoni yokufambisa motokari. Nyanzvi dzakashandisa simba rinowanikazve kuti dzishandure carbon dioxide nemvura kuti zvive mafuta asina kuchena anozivikanwa se'blue crude oil,' ayo aibva acheneswa kuti ave mafuta edhiziri. Dzorera pasi kuti uone vhidhiyo. Audi inotaura kuti yakagadzira mafuta emangwana - diesel (inoratidzwa pamusoro apa) yakagadzirwa nemvura uye carbon dioxide. Nyanzvi dzinoshandisa simba rinowanikwazve kushandura carbon dioxide nemvura kuva rudzi rwezvinhu zvisina kuchena zvinozivikanwa se'blue crude oil', iyo inobva yagadziriswa kuva diesel. Miedzo yakaratidza kuti inogona kusanganiswa nedhiziri inobva mumafuta, kana kuti kushandiswa sechinhu chinotsigira motokari pachayo. Audi yakatotanga kushandisa e-diesel itsva kupa simba motokari yebasa yomukuru mukuru weGermany wedzidzo nokutsvakurudza Dr. Johanna Wanka. Reiner Mangold, mukuru wezvokugadzirwa kwezvinhu zvinogadzirika paAudi, akati: "Mukugadzira Audi e-diesel tiri kukurudzira imwe mafuta yakavakirwa pa carbon dioxide iyo ichabvumira kufamba kwemakiromita marefu pasina chinenge chisina kukanganisa mamiriro okunze. Mafuta eAudi akagadzirwa neSunfire, kambani yoruzivo rwokugadzira magetsi yeDresden. Kuti agadzire mafuta acho, mvura inotanga kupiswa kuti iite mhute iyo inobva yaputswa kuita hydrogen uye okisijeni ichishandisa electrolysis inopisa zvikuru. Nokuita izvi patembiricha inopfuura 800°C (1,472°F), mvura inoparara zvinobudirira zvikuru kupfuura patembiricha yomukamuri. Hydrogen yacho inobva yapomberwa mu reactor ine carbon dioxide pakumanikidzwa kwakakwirira uye tembiricha yakakwirira. Ikoku kunozviparira kuita kuti zvibudise mahydrocarbon emvura ane ngetani refu. Mahydrocarbon ndiwo anovaka mafuta ose anogadzirwa nemakemikari, asi zvinhu zvinogadzirwa mumagetsi zvinonzi "blue crude". Audi inotaura kuti muitiro wose unogona kupiwa simba uchishandisa simba rinowanikwazve uye unogona kuwanikwa nekubudirira kweanenge 70%. Petroli yakasvibirira inogona kunatswa nenzira yakafanana neyemafuta akasvibirira enguva dzose kuti...
Mugadziri wemotokari wokuGermany akashandisa simba rinowanikwazve kuti ashandure carbon dioxide nemvura kuva 'blue crude' oiri iyo yaizonatswa kuva dizero. Carbon dioxide inogona kubviswa mumhepo kana kuti muzvirimwa zvemagetsi. Audi inotaura kuti e-diesel yayo haina kabhoni isingakonzeri kuchinja kwemamiriro okunze. Miedzo inoratidza kuti inobvumira motokari kumhanya chinyararire uye kubudisa tsvina shomanene.
