Isibaseli ukucabanga

ENingizimu Melika, izimoto zisebenzisa i-ethanol iminyaka ngaphandle kwesigameko. Kodwa ngaphandle kokwengeza ingcosana yale nto kuphethiloli wethu ongenamthofu, ayikagxili lapha.

Futhi nalesi samba esincane asizange sibe ngaphandle kwengxabano, nezinsolo zokuthi zingalimaza izinjini.

Lokho kungase kushintshe, nokho, ngokufika kwezimoto ze-Saab BioPower eziklanyelwe ngokuqondile ukusebenzisa i-ethanol, eholwa yi-Saab 9-5 BioPower.

Asikhulumi nge-10%, kodwa i-E85 noma i-85% ye-ethanol ehlanzekile, ehlanganiswe ne-15% kaphethiloli ongenantambo.

Nakuba i-E85 idinga izinguquko ezithile zobuchwepheshe ukuze isebenze, i-Saab ithi ayidingi ubuchwepheshe obukhethekile. Izimoto ze-BioPower zizosebenza ngempumelelo kukho kokubili uphethiloli kanye ne-ethanol, kodwa ezinye izinguquko zizodingeka ngaphambi kokuba uqale ukugcwalisa ithangi nge-ethanol ngenxa yokugqwala kwayo.

Lokhu kufaka phakathi ukwengezwa kwamavalvu aqinile nezihlalo zamavalvu, kanye nokusetshenziswa kwezinto ezihambisana ne-ethanol ohlelweni lukaphethiloli, okuhlanganisa ithangi, iphampu, imigqa, nezixhumi. Ukubuyisela, uthola uphethiloli ohlanzekile osebenza kangcono ngenxa yokulinganisa okuphezulu kwe-octane. I-trade-off ukuthi ushisa kakhulu.

I-Ethanol iwutshwala obutholakala ngokuxutshwa kokusanhlamvu, i-cellulose noma umoba. Yenziwe ngomoba eBrazil iminyaka eminingi, futhi ibuye yenziwe ngommbila e-US Midwest.

E-Sweden, ikhiqizwa nge-pulp yezinkuni kanye nemfucumfucu yehlathi, futhi ucwaningo olungenzeka luyenziwa ukuze kubonakale ukuthi ingakhiqizwa yini nge-lignocellulose.

Njengophethiloli, umehluko obaluleke kakhulu phakathi kukaphethiloli ne-ethanol ukuthi i-ethanol ayinyusi amazinga e-carbon dioxide (CO2).

Lokhu kungenxa yokuthi i-CO2 ikhishwa emkhathini ngesikhathi se-photosynthesis izitshalo ezitshalwe ukukhiqiza i-ethanol.

Into eyinhloko, yiqiniso, ukuthi i-ethanol ivuselelwa, kodwa amafutha awekho. I-Saab okwamanje inikeza izinguqulo ze-BioPower zezinjini zayo ezingama-2.0- kanye ne-2.3-litre turbocharged four-cylinder.

Imoto yethu yokuhlola bekuyinqola yesiteshi engu-2.0 litre ebhalwe ukuthi "Saab BioPower" eceleni. Ngokujwayelekile le njini ikhiqiza amandla angu-110kW kanye ne-torque engu-240Nm, kodwa nge-octane ephakeme i-E85 104RON, leso sibalo sikhuphukela ku-132kW kanye no-280Nm.

Inqola, yiqiniso, ineziphu eziningi, kodwa ngesikhathi esifanayo, kubonakala sengathi ihlafuna ithangi eligcwele le-E85 ngokushesha.

Besingakahambi ibanga elingu-170 km ngesikhathi ithangi elingu-68-litre (hhayi elijwayelekile elingu-75-litre) liba yingxenye engenalutho, kwathi ngo-319 km kwakhanya ilambu likaphethiloli eliphansi.

Ngebanga lika-347 km, ikhompuyutha esebhodini yafuna ukufaka uphethiloli emotweni. Uma uhlela uhambo olude lokhu kungaba inkinga njengoba kuneziteshi zikaphethiloli eziyingxenye yeshumi nambili eNew South Wales ezihlinzeka nge-E85. Ngesikhathi sigcwalisa ithangi, ikhompuyutha esebhodini ibikhombisa ukuthi isebenzisa amalitha angu-13.9 ngebanga lika-100 km.

Nokho, ithangi kuphela ephethe 58.4 amalitha E85, okuyinto, ngokubala kwethu, kwaba 16.8 amalitha 100 km ngalinye - cishe efanayo grey V8 ubudala.

Azikho izibalo ezisemthethweni zokusebenzisa uphethiloli nge-9-5 BioPower, kodwa uma uyiqhathanisa, yona le moto enenjini engu-2.0 litre ikhiqiza amalitha angu-10.6 ngebanga lika-100 km.

Yebo, lokhu kufanele kukalwe ngezindleko ze-E85 (amasenti angu-85.9 ilitha ngesikhathi sigcwalisa) uma kuqhathaniswa nophethiloli ongafakwa umthamo, odayiswe nge-servo efanayo ngo-116.9 cents - 26.5% ngaphansi. Kodwa-ke, njengoba besishisa uphethiloli ongu-58% ngaphezulu, lokhu empeleni bekuyi-31.5% ngemuva kwabayisishiyagalombili abahamba phambili.

Khonamanjalo, iSaab ithi ukusetshenziswa kukaphethiloli kweBioPower kucishe kufane nokwemodeli kaphethroli ehamba ngesivinini esingaguquki. Kodwa ezimeni zokushayela ezixubile, isebenzisa cishe amaphesenti angama-25-30 ngaphezulu kwe-E85. Ukukhishwa kwekhabhoni enjinini kaphethiloli kungu-251 amagremu, futhi azikho izibalo ze-ethanol.
