I-prototype yokuhlola ye-Toyota GR Yaris H2 yaboniswa ngesikhathi se-Kenshiki Forum futhi yabelana ngenjini ye-hydrogen ne-Corolla Sport eqhudelana ekuqeqesheni i-Super Taikyu e-Japan.
Phansi kwale njini kukhona injini ye-G16E-GTS, yona kanye i-turbocharged engu-1.6 l in-line block three-cylinder esesiyazi kusukela ku-GR Yaris, kodwa ejwayele ukusebenzisa i-hydrogen njengophethiloli esikhundleni sikaphethiloli.
Naphezu kokusetshenziswa kwe-hydrogen, akuwona ubuchwepheshe obufanayo esithola, isibonelo, kuToyota Mirai.
I-Mirai iyimoto kagesi esebenzisa i-hydrogen fuel cell (egcinwe ku-high-pressure tank) okuthi, lapho isabela nge-oxygen emoyeni, ikhiqize amandla kagesi adingekayo adingwa yimoto kagesi (amandla agcinwe ezigubhu) .
Kule GR Yaris H2, njengasendabeni yomjaho iCorolla, i-hydrogen isetshenziswa njengophethiloli enjinini evuthayo yangaphakathi, njengokuthi injini kaphethiloli.
Yiziphi izinguquko?
Kukhona nokho umehluko phakathi kwe-hydrogen G16E-GTS kanye nophethiloli i-G16E-GTS.
Ngokubikezelwa, ukudla kukaphethiloli kanye nesistimu yomjovo kwadingeka kushintshwe ukuze kusetshenziswe i-hydrogen njengophethiloli. Ibhulokhi nayo yaqiniswa, njengoba ukushiswa kwe-hydrogen kushube kakhulu kunophethiloli.
Lokhu kusha ngokushesha kuphinde kuphumele ekuphenduleni kwenjini okuphakeme futhi ukusebenza kahle okuqondile vele kuyadlula injini efanayo kaphethiloli, okungenani uma kubhekwa izitatimende zakwaToyota mayelana nokuvela kokusebenza kwenjini esetshenziswa kwiCorolla emqhudelwaneni.
Kusuka ku-Mirai, le GR Yaris H2 enenjini ye-hydrogen izuza ifa lesistimu yokugcwalisa i-hydrogen, kanye namathangi afanayo anengcindezi ephezulu.
Yiziphi izinzuzo zenjini ye-hydrogen?
Lokhu kubheja kweToyota kuyingxenye yemizamo ekhulayo yesikhondlakhondla saseJapan sokugqugquzela ukusetshenziswa kwe-hydrogen - kungakhathaliseki ukuthi ezimotweni zikaphethiloli njenge-Mirai, noma manje njengophethiloli ezinjinini ezivuthayo zangaphakathi, njengakulesi sibonelo se-GR Yaris - ukuze kuzuzwe ukungathathi hlangothi kwe-carbon.
Ukusha kwe-hydrogen enjinini evuthayo yangaphakathi kuhlanzeke ngokwedlulele, akukhiqizi i-CO2 (carbon dioxide) ephumayo. Kodwa-ke, ukukhishwa kwe-CO2 akuyona i-zero ngokuphelele, ngenxa yokuthi isebenzisa uwoyela njengento yokugcoba, ngakho-ke "inani elincane lamafutha enjini liyashiswa ngenkathi ushayela".
Enye inzuzo enkulu, evumelana kakhulu futhi ngokuqinisekile nokuthandwa kwawo wonke ama-petrolheads ukuthi ivumela ulwazi lokushayela ukuthi luhlale lufana nolwenjini evamile evuthayo yangaphakathi, kungakhathaliseki ukuthi ikwimodi yayo yokusebenza noma ezingeni lemizwa. , ikakhulukazi i-acoustic.
Ingabe i-GR Yaris esebenza nge-hydrogen izofinyelela ekukhiqizeni?
I-GR Yaris H2 iyisibonelo nje okwamanje. Lobu buchwepheshe busathuthukiswa kanti kwaToyota basebenzise umhlaba wokuncintisana ukubuthuthukisa ngeCorolla emqhudelwaneni weSuper Taikyu.
Okwamanje abakwaToyota abaqinisekisi ukuthi izokhiqizwa noma cha iGR Yaris H2, futhi kungashiwo okufanayo nangenjini ye-hydrogen uqobo.
Kodwa-ke, amahlebezi akhombisa ukuthi injini ye-hydrogen izoba ngokoqobo kwezohwebo futhi kungenzeka kube enye yezinhlobo ezixubile zakwaToyota ukuyikhipha okokuqala:
