Uma uthi nhlá akwenzi mqondo: izinjini ezinkulu ukuze zihlangabezane nezindinganiso zokukhishwa kwekusasa? Yilokho uFrank-Steffen Walliser, umqondisi wezemidlalo kwa-Porsche, atshele incwadi yase-Australia ethi Wheels, ekhuluma ngekusasa le-911.
Izinga elilandelayo lokukhishwa kwegesi elizoqala ukusebenza eYurophu kuzoba yi-Euro7 futhi, ngokusho kukaWalliser, kuzoba izindinganiso eziqine kakhulu zokukhipha umoya emhlabeni, ikakhulukazi ngokwehlukana phakathi kwesisi esitholakala ezivivinyweni nasezimeni zangempela.
Ukufeza zonke izidingo, okuwukuphela kwesixazululo esibonakalayo, okwamanje, ukubuyela emuva ekusebenziseni izinjini ezinkulu, njengasendabeni ye-911, futhi ngisho… ngenani lamasilinda, esimweni sabanye abakhiqizi.
UFrank-Steffen Walliser, Umqondisi Wezemidlalo kwa-Porsche"Ngibona kusengaphambili u-20% womthamo owengeziwe ngokwesilinganiso walezi zinjini ezithobela i-Euro7. Abakhiqizi abaningi bazogxuma ukusuka kwezine ziye kweziyisithupha (amasilinda), zisuka kweziyisithupha ziye kweziyisishiyagalombili (isilinda)."
Kodwa kwenzekani ngokuncipha kwabasebenzi?
I-Euro7 ihlanganisa izivivinyo ezintsha zokukhishwa kwekhabhoni ngokubanda kwenjini, khona kanye lapho izinjini ezivuthayo zingcolisa kakhulu, njengoba ama-catalyst engekho ezingeni lokushisa elifanele lokusebenza (lokhu kuyehluka, kodwa amanani ebangeni elingu-600º C ajwayelekile).

Lokhu kuzophoqa ukuba kube nama-catalyst amakhulu njengoba uWalliser esho: “uma ngithi enkulu, ngikhuluma ngesici esiphindwe kathathu noma kane esikhulu, ngakho sizoba nefekthri encane yamakhemikhali ezimboni emotweni ukuze silawule lokhu”; futhi izonciphisa amandla athile enjini (amahhashi ilitha ngalinye). Isixazululo? Khulisa izinjini.
Uma ukwehliswa kwabantu esibe nakho kule minyaka eyishumi edlule kugxile ekwehliseni ukukhishwa kwe-CO2, manje, njengokungqubuzana, kuzodingeka sichithe uphethiloli owengeziwe (Ukusetshenziswa kanye nokukhishwa kwe-CO2 kuyahambisana), ukulwa namanye amagesi e-exhaust (NOx nama-particle, ngaphezu kwakho konke). UFrank-Steffen Walliser:
“Asikwazi ukuhlangabezana nayo yonke imithetho ngaphandle kokumosha uphethiloli. Kuzwakala njengokuhlanya, kodwa kuyiqiniso lobuchwepheshe okwamanje.”
Lokhu kusho ukuthi esikhathini esizayo se-Porsche 911 sizobona injini eyodwa noma eziningana ezintsha. Laba bazoqhubeka nokuba ngabashayisibhakela abayisixcylinder kodwa bazoba izinjini ezinkulu. Okwamanje asikho esinye isixazululo esisibonayo ngaphandle kokusetshenziswa kwe-supercharging (turbos), nayo efaka imibuzo ngezinjini ezishibhile ngokwemvelo esinazo njengamanje kwi-911 GT3 kanye ne-911 GT3 RS.
Ithimba likaRazão Automóvel lizoqhubeka ku-inthanethi, amahora angama-24 ngosuku, ngesikhathi sokugqashuka kwe-COVID-19. Landela izincomo zoMqondisi Jikelele Wezempilo, gwema ukuhamba okungenasidingo. Ngokubambisana sizokwazi ukunqoba lesi sigaba esinzima.
