Kunyaka ophelileyo, i-website esemthethweni yoLawulo lwaMandla kaZwelonke yazisa ukuba ukunyuswa kwepetroli ye-ethanol kuya kukhawuleziswa kwaye kwandiswe, kwaye ukugubungela ngokupheleleyo kuya kufezekiswa ngokukhawuleza ngo-2020. Oku kuthetha ukuba kwiminyaka emi-2 ezayo, siya kuqalisa ngokuthe ngcembe. sebenzisa i-E10 ethanol petroli ene-ethanol eyi-10%. Ngapha koko, i-E10 petroli ye-ethanol sele iqalile umsebenzi wokulinga kwango-2002.
Yintoni i-ethanol petroli? Ngokwemigangatho yelizwe lam, i-ethanol petroli yenziwa ngokuxuba i-90% yepetroli eqhelekileyo kunye ne-10% ye-ethanol yamafutha. I-10% ye-ethanol ngokubanzi isebenzisa umbona njengento ekrwada. Isizathu sokuba ilizwe lidume kwaye likhuthaze ipetroli ye-ethanol ikakhulu ngenxa yeemfuno zokhuseleko lokusingqongileyo kunye nokwanda kwemfuno yasekhaya kunye nokwanda kwemfuno yokutya okuziinkozo (umbona), kuba ilizwe lam linesivuno esikhulu sokutya okuziinkozo minyaka le. ukuqokelelwa kweenkozo ezindala kukhulu. Ndiyakholwa ukuba wonke umntu ubone iindaba ezininzi ezinxulumeneyo. ! Ukongeza, imithombo ye-parafini yelizwe lam inqabile, kwaye ukuphuhliswa kwesibaso se-ethanol kunokunciphisa ukuxhomekeka kwi-kerosene evela kumazwe angaphandle. I-Ethanol ngokwayo luhlobo lwesibaso. Emva kokuxuba umlinganiselo othile we-ethanol, inokugcina izixhobo ezininzi ze-kerosene xa kuthelekiswa nepetroli esulungekileyo phantsi komgangatho ofanayo. Ke ngoko, i-bioethanol ithathwa njengenye imveliso enokutshintsha amandla efosili.
Ngaba i-ethanol petroli inefuthe elikhulu kwiimoto? Okwangoku, iimoto ezininzi kwimarike zinokusebenzisa i-ethanol petroli. Ngokubanzi, ukusetyenziswa kwepetroli ye-ethanol kuphezulu kancinci kunepetroli esulungekileyo, kodwa inani le-octane liphezulu kancinci kwaye ukusebenza kokuchasana nokunkqonkqoza kungcono kancinci. Xa kuthelekiswa nepetroli eqhelekileyo, i-ethanol ngokungathanga ngqo iphucula ukusebenza kakuhle kwe-thermal ngenxa yomxholo we-oksijini ephezulu kunye nokutsha okupheleleyo. Nangona kunjalo, kungenxa yeempawu ze-ethanol ezahlukileyo kwipetroli. Xa kuthelekiswa nepetroli eqhelekileyo, i-ethanol inamandla angcono kwisantya esiphezulu. Amandla mabi ngakumbi kwii-revs eziphantsi. Enyanisweni, i-ethanol petroli isetyenziswe eJilin ixesha elide. Ukuthetha ngenjongo, inempembelelo kwisithuthi, kodwa ayicacanga, ngoko akufanele ukhathazeke!
Ngaphandle kweTshayina, ngawaphi amanye amazwe akhuthaza i-ethanol petroli? Okwangoku, elona lizwe liphumeleleyo ekukhuthazeni i-ethanol petroli yiBrazil. IBrazil ayingowesibini ngobukhulu umvelisi we-ethanol kwihlabathi, kodwa ikwalelona lizwe liphumelele kakhulu ekukhuthazeni i-ethanol petroli emhlabeni. Kwangowe-1977, iBrazil yayisebenzisa ipetroli ye-ethanol. Ngoku, zonke izikhululo zegesi eBrazil azinayo i-petroli ecocekileyo yokongeza, kwaye yonke i-petroli ye-ethanol enomxholo osuka kwi-18% ukuya kwi-25% iyathengiswa.
