Mafuta ekufunga
MuSouth America, motokari dzinoshandisa ethanol kwemakore pasina chiitiko. Asi kunze kwekuwedzera chidimbu chechinhu ichi papeturu yedu isina lead, haisati yadzika midzi pano.
Uye kunyange iyi shoma shoma haina kumbove pasina kukakavara, nekutaura kuti inogona kukuvadza injini.
Izvo zvinogona kuchinja, zvisinei, nekuuya kweSaab BioPower mota dzakagadzirirwa chaizvo kumhanya pa ethanol, inotungamirwa neSaab 9-5 BioPower.
Hatisi kutaura nezve 10%, asi E85 kana 85% yakachena ethanol, iyo inosanganiswa ne15% unleaded peturu.
Kunyange iyo E85 ichida shanduko yehunyanzvi kuti imhanye, Saab inoti haidi chero tekinoroji yakakosha. Mota dzeBioPower dzinomhanya zvinobudirira papeturu ne ethanol, asi kumwe kugadziridzwa kunozodiwa usati watanga kuzadza tangi ne ethanol nekuda kwekuora kwayo.
Izvi zvinosanganisira kuwedzerwa kwemavharuvhu akasimba uye zvigaro zvevharuvhu, uye kushandiswa kwezvinhu zvinopindirana ethanol muhurongwa hwemafuta, kusanganisira tangi, pombi, mitsetse, uye zvibatanidza. Mukudzoka, iwe unowana yakachena mafuta nekuita zvirinani nekuda kwepamusoro octane chiyero. Kutengeserana ndiko kuti unopisa zvakanyanya.
Ethanol idoro rinowanikwa nekunyungudutswa kubva muzviyo, cellulose kana nzimbe. Yakagadzirwa kubva kunzimbe muBrazil kwemakore mazhinji, uye zvakare kubva kuchibage muUS Midwest.
MuSweden, inogadzirwa kubva muhuni hwehuni uye marara emasango, uye zvidzidzo zvinogoneka zviri kuitwa kuti vaone kana inogona kugadzirwa kubva ku lignocellulose.
Sehuni, musiyano unonyanya kukosha pakati pepeturu ne ethanol ndewekuti ethanol haiwedzere mazinga ecarbon dioxide (CO2).
Izvi zvinodaro nekuti CO2 inobviswa mumhepo panguva yephotosynthesis nezvirimwa zvinorimwa kugadzira ethanol.
Chinhu chikuru, chokwadi, ndechokuti ethanol inogona kudzorerwa, asi mafuta haasi. Saab parizvino inopa BioPower vhezheni yayo 2.0- uye 2.3-litre turbocharged ina-cylinder injini.
Mota yedu yekuyedza yaive 2.0-litre station wagon ine "Saab BioPower" yakanyorwa padivi. Kazhinji injini iyi inounza 110kW ne240Nm yetorque, asi ine octane yepamusoro E85 104RON, nhamba iyoyo inokwira kusvika ku132kW ne280Nm.
Ngoro, hongu, ine zip yakawanda, asi panguva imwe chete, yaiita seyakakurumidza kutsenga tangi rakazara reE85.
Isu takanga tisina kumboenda 170 km apo 68-litre (kwete yakajairwa 75-liter) tangi yakava hafu isina chinhu, uye pa319 km mwenje wemafuta wakadzika wakauya.
Pamakiromita 347, komputa iri pabhodhi yakada kuwedzera mafuta mumotokari. Kana uri kuronga nzendo dzenzendo refu iri rinogona kuve dambudziko sezvo kuchingori nehafu gumi nemaviri zviteshi zvegasi muNew South Wales zvinopa E85. Patakasimudza tangi, komputa iri pabhodhi yakaratidza kushandisa mafuta emarita 13.9 pamakiromita zana.
Zvisinei, tangi yakangobata 58.4 malita eE85, iyo, nekuverenga kwedu, yaiva 16.8 malita pa100 km - inenge yakafanana neyekare grey V8.
Iko hakuna huwandu hwehuwandu hwekushandisa mafuta e9-5 BioPower, asi kuenzanisa, mota imwe chete ine 2.0-litre peturu injini inoburitsa inonzi 10.6 l/100 km.
Ehe, izvi zvinofanirwa kuyerwa nemutengo weE85 (85.9 masendi parita patakazadza) zvichienzaniswa nepeturu isina lead, iyo yakatengeswa nesevha imwe chete ye116.9 cents - 26.5% pasi. Zvisinei, sezvo takanga tichipisa 58% mamwe mafuta, izvi chaizvoizvo 31.5% shure kwevasere vepamusoro.
Saab, zvakadaro, inotaura kuti kushandiswa kwemafuta kweBioPower kwakada kufanana neiyo yemodhi yepeturu painomhanya inogara ichifamba. Asi mumamiriro ezvinhu akasanganiswa ekutyaira, inoshandisa inenge 25-30 muzana yakawanda E85. Carbon emissions yeinjini yepeturu i251 gramu, uye hapana nhamba dze ethanol.
