Ngonyaka odlule, iwebhusayithi esemthethweni ye-National Energy Administration yamemezela ukuthi ukukhuthazwa kukaphethiloli we-ethanol kuzosheshiswa futhi kwandiswe, futhi ukutholakala okugcwele kuzotholakala ngokushesha nje ngo-2020. Lokhu kusho futhi ukuthi eminyakeni engu-2 ezayo, sizoqala kancane kancane sebenzisa i-E10 ethanol petroli ene-ethanol engu-10%. Eqinisweni, uphethiloli we-ethanol we-E10 usuvele waqala umsebenzi wokuhlola kusukela ngo-2002.
Iyini i-ethanol petroli? Ngokwezindinganiso kazwelonke zezwe lami, uphethiloli we-ethanol wenziwa ngokuhlanganisa uphethiloli ojwayelekile ongu-90% no-10% we-ethanol kaphethiloli. I-ethanol engu-10% ngokuvamile isebenzisa ummbila njengento eluhlaza. Isizathu esenza izwe lidume futhi likhuthaze uphethiloli we-ethanol kungenxa yezidingo zokuvikelwa kwemvelo kanye nokwanda kwesidingo sasekhaya kanye nokwanda kwesidingo sokusanhlamvu (ummbila), ngoba izwe lami linesivuno esikhulu sokusanhlamvu minyaka yonke, ukunqwabelana kokusanhlamvu okudala kukhulu. Ngikholwa ukuthi wonke umuntu ubone izindaba eziningi ezihlobene. ! Ngaphezu kwalokho, izinsiza zikaphalafini zezwe lami ziyindlala uma kuqhathaniswa, futhi ukuthuthukiswa kukaphethiloli we-ethanol kunganciphisa ukuncika kuphalafini ovela kwamanye amazwe. I-Ethanol ngokwayo iwuhlobo lwamafutha. Ngemva kokuxuba inani elithile le-ethanol, lingonga izinsiza eziningi zikaphalafini uma kuqhathaniswa nophethiloli omsulwa ngaphansi kwekhwalithi efanayo. Ngakho-ke, i-bioethanol ibhekwa njengomkhiqizo ohlukile ongashintsha amandla ezinsalela.
Ingabe uphethiloli we-ethanol unomthelela omkhulu ezimotweni? Njengamanje, izimoto eziningi emakethe zingasebenzisa uphethiloli we-ethanol. Ngokuvamile, ukusetshenziswa kukaphethiloli kaphethiloli we-ethanol kuphakeme kancane kunophethiloli omsulwa, kodwa inombolo ye-octane iphakeme kancane futhi ukusebenza kwe-anti-knock kungcono kancane. Uma iqhathaniswa nophethiloli ojwayelekile, i-ethanol ithuthukisa ngokungaqondile ukusebenza kahle kokushisa ngenxa yokuqukethwe komoya-mpilo ephezulu kanye nokusha okuphelele. Nokho, kungenxa yezimpawu ze-ethanol ezihlukile kuphethiloli. Uma kuqhathaniswa nophethiloli ojwayelekile, uphethiloli we-ethanol unamandla angcono ngesivinini esikhulu. Amandla mabi nakakhulu kuma-revs aphansi. Eqinisweni, uphethiloli we-ethanol ususetshenziswe isikhathi eside eJilin. Uma sikhuluma ngendlela eqondile, inomthelela emotweni, kodwa ayibonakali, ngakho akumele ukhathazeke!
Ngaphandle kweChina, yimaphi amanye amazwe akhuthaza uphethiloli we-ethanol? Njengamanje, izwe eliphumelele kakhulu ekukhuthazeni uphethiloli we-ethanol yiBrazil. I-Brazil ayiyona nje isibili ngobukhulu emhlabeni ngokukhiqiza uphethiloli we-ethanol, kodwa futhi iyizwe eliphumelele kakhulu ekukhuthazeni uphethiloli we-ethanol emhlabeni. Kusukela ngo-1977, iBrazil yayisebenzisa uphethiloli we-ethanol. Manje, zonke iziteshi zikaphethiloli eBrazil azinawo uphethiloli omsulwa ongawengeza, futhi wonke uphethiloli we-ethanol onokusuka ku-18% kuya ku-25% uyathengiswa.
