Pakutanga kuona hazvina musoro: injini hombe kusangana neramangwana emission standard? Ndizvo zvakataurwa naFrank-Steffen Walliser, director wemitambo kuPorsche, akaudza bhuku reAustralia mavhiri, achitaura nezveramangwana re911.
Iyo inotevera emission standard kuti itange kushanda muEurope ichave Euro7 uye, sekureva kwaWalliser, ichave yakaomesesa emission zviyero papasi, kunyanya maererano nekusiyana pakati pekubuda kunowanikwa mukuyedzwa uye mumamiriro chaiwo.
Kuzadzisa zvese zvinodiwa, mhinduro chete iri kuona, ikozvino, ndeye kudzokera kukushandisa injini hombe, sezvakaitika kune iyo 911, uye kunyangwe…
Frank-Steffen Walliser, Mutungamiriri weMitambo paPorsche"Ini ndinofanoona 20% kuwedzera huwandu paavhareji kune idzi injini dzinoenderana neEuro7. Vagadziri vakawanda vachasvetuka kubva paina kusvika panhanhatu (cylinder), kubva pamatanhatu kusvika masere (cylinder)."
Asi chii chakaitika pakuderedzwa?
Euro7 inosanganisira miedzo mitsva yekubuda nejini inotonhora, chaizvo kana injini dzemoto dzichisvibisa zvakanyanya, sezvo zvinokonzeresa zvisiri patembiricha yekushanda (izvi zvinosiyana, asi kukosha mu600º C kwakajairwa).
Nyorera kune tsamba yedu
Ikoku kuchamanikidzira kuva nezvinokonzeresa zvikuru sokutaura kunoita Walliser: “apo ndinotaura zvikuru, ndiri kutaura pamusoro pechimwe chinhu chakapetwa katatu kana kuti kana, naizvozvo tichava nefekitari duku yamakemikari okugadzira zvinhu mumotokari kudzora ikoku”; uye ichamisawo simba chairo reinjini (mabhiza parita). Mhinduro yacho? Kurisa injini.
Kana kudzikisira kwatakaita mumakore gumi apfuura kwakanangana nekuderedza kuburitswa kweCO2, iko zvino, sekupesana, tichazoshandisa mafuta akawanda (Kushandisa uye CO2 emissions inofambidzana), kurwisa mamwe magasi emhepo (NOx uye zvikamu, pamusoro pezvose). Frank-Steffen Walliser:
“Hatikwanise kuita zvese zvinodiwa pasina kutambisa mafuta. Zvinoita sekupenga, asi ichokwadi chehunyanzvi parizvino. "
Izvi zvinoreva kuti mune ramangwana rePorsche 911 tichaona imwe kana dzinoverengeka injini itsva. Aya acharamba ari matanhatu-cylinder boxer asi achange ari mainjini makuru. Parizvino hapanazve imwe mhinduro mukuona kunze kwekushandiswa kwe supercharging (turbos), iri kuisawo mubvunzo nezve injini dzinoshuvira dzatinadzo parizvino mu911 GT3 uye 911 GT3 RS.
Chikwata cheRazão Automóvel chicharamba chiri pamhepo, maawa makumi maviri nemana pazuva, panguva yekubuda kweCCIDID-19. Tevedzera kurudziro yeGeneral Directorate yehutano, dzivirira kufamba kusingakoshi. Pamwe chete tichakwanisa kukunda chikamu chakaoma ichi.
