Abavelisi beemoto kunye namalungu achanekileyo bahlala bejonge izinto ezintsha nezisebenzayo ngakumbi ukunyusa ukucaciswa kunye nokusebenza kweemveliso zabo.Abenzi beemoto banomdla ngakumbi ekusebenziseni izinto ezintsha kwizithuthi zabo, ezikhokelela ekulingeni ngeentlobo ezahlukeneyo zentsimbi kunye nealloyi ye-aluminiyam.

IFord kunye neGeneral Motors, umzekelo, zibandakanye ezi zinto kwizithuthi zabo ukunciphisa ubunzima obupheleleyo boomatshini babo kwaye baqinisekise amandla kunye nokuqina, ingxelo yoyilo.I-GM yanciphisa ubunzima be-chevy Corvette's chassis nge-99 pounds ngokutshintshela kwi-aluminiyam, ngelixa i-Ford yanciphisa malunga ne-700 yeponti ukusuka kubunzima obupheleleyo be-F-150 kunye nendibaniselwano yentsimbi ephezulu kunye ne-alloys ye-aluminium.

"Wonke umenzi wemoto kufuneka ayenze," uBart DePompolo, umphathi wentengiso yemoto e-US Steel Corp., uxelele umthombo."Bathathela ingqalelo yonke into abanokuyikhetha, yonke into."
Inani lezinto ezinegalelo kwimfuno yezinto eziphambili zokuvelisa iimoto, kubandakanywa nemigaqo-nkqubo yoqoqosho lwe-fuel ephakathi, ngokutsho kweendaba.Le migangatho ifuna abavelisi beemoto bafikelele kwi-avareji yokusebenza kwepetroli ye-54.5 ngo-2025 kubo bonke oomatshini abaveliswa kwishishini liphela.

Izinto ezinobunzima obuphantsi, amandla aphezulu anokuba negalelo ekuphuculeni uqoqosho lwepetroli, nto leyo ezenza zibe ziinketho ezinomtsalane zokuhlangabezana neemfuno zikarhulumente.Ukuncipha kobunzima bezi mathiriyeli kubeka ubunzima obuncinci kwiinjini, kwaye zifuna ukusetyenziswa kwamandla okuncinci.

Imigangatho engqongqo yokuphahlazeka ikwaphakathi kwengqwalasela ekhuthaza ukusetyenziswa kweentsimbi eziphambili kunye nealloys aluminiyam.Le migaqo ifuna ukudityaniswa kwezinto ezomeleleyo kumacandelo athile emoto, afana noluhlu lwecab.

"Ezinye zeentsimbi eziphezulu kakhulu zisetyenziselwa iintsika zophahla kunye nama-rockers, apho kufuneka ulawule amandla amaninzi okuphahlazeka," uTom Wilkinson, umkhulumeli weChevy, utshele umthombo."Emva koko uya kwintsimbi encinci yexabiso eliphantsi kwiindawo apho ungadingi mandla angako."

Ubunzima boyilo

Nangona kunjalo, ukusetyenziswa kwezi zixhobo kubangela imingeni kwiinjineli, ezijongene neendleko kunye nokusebenza kakuhle.Olu rhwebo lwenziwa mandundu ngakumbi kukuba iiprojekthi ezininzi zokuvelisa iimoto ziqalwa kwiminyaka ngaphambi kokuba izithuthi zikhutshelwe emarikeni.

Abaqulunqi kufuneka bafumanise iindlela zokudibanisa izixhobo ezitsha kwimveliso yeemoto kunye nokwenza izinto ngokwabo, ngokutsho komthombo.Bakwafuna ixesha lokusebenzisana nabasasazi ukwenza i-aluminium ivumela kunye neentsimbi.

"Kuthiwa i-50 pesenti yeentsimbi kwiimoto zanamhlanje azizange zibekho kwiminyaka eyi-10 eyadlulayo," utshilo uDePompolo."Oko kukubonisa ukuba le nto iguquka ngokukhawuleza kangakanani."

Ngaphezu koko, ezi zixhobo zinokubiza kakhulu, zibalela ukuya kuthi ga kwi-1,000 yeedola zexabiso lenani lezithuthi ezitsha, inqaku leendaba latsho.Ukuphendula kwiindleko eziphezulu, i-GM ikhethe iintsimbi ngaphezu kwe-aluminium kwiimeko ezininzi.Ngokufanelekileyo, iinjineli kunye nabavelisi kufuneka bafumane iindlela zokulinganisa ukusebenza kunye neendleko zezi zinto ziphambili.
