U-Liebherr uzokhombisa okokuqala izinjini zakhe ze-hydrogen prototype e-Bauma 2022.
Kwa-Bauma 2022, ingxenye yomkhiqizo wezingxenye ze-Liebherr yethula ama-prototypes amabili enjini yayo ye-hydrogen ezindaweni zokwakha zakusasa.I-prototype ngayinye isebenzisa ubuchwepheshe obuhlukene bomjovo we-hydrogen, umjovo oqondile (DI) kanye nomjovo wamafutha echwebeni (PFI).
Ngokuzayo, izinjini ezivuthayo ngeke zisanikezwa amandla udizili wezinto ezimbiwa phansi kuphela.Ukuze kuzuzwe ukungathathi hlangothi kwesimo sezulu ngo-2050, kuzofanele kusetshenziswe amafutha avela emithonjeni yamandla esimeme.I-hydrogen eluhlaza ingenye yazo, njengoba ingamafutha athembisayo angenayo i-carbon, engadali noma yikuphi ukukhishwa kwe-CO2 ngenkathi ivutha ngaphakathi kwenjini yomlilo yangaphakathi (ICE).
Ubuchwepheshe buka-Liebherr ekuthuthukisweni kwama-ICE buzophinde busize ukwethulwa okusheshayo kobuchwepheshe be-hydrogen emakethe.
Izinjini ze-Hydrogen: ikusasa elithembisayo
Ingxenye yomkhiqizo we-Liebherr components isanda kwenza utshalomali olukhulu ekuthuthukisweni kwenjini yayo ye-hydrogen nezindawo zokuhlola.Izinjini ze-prototype zihlolwe kusukela ngo-2020. Khonamanjalo, ama-prototypes abonise imiphumela ekhuthazayo mayelana nokusebenza kanye nokukhipha, kokubili emabhentshini okuhlola nasensimini.
Ubuchwepheshe obuhlukene bomjovo kanye nokuvutha, obufana nomjovo kaphethiloli wembobo (PFI) nomjovo oqondile (DI), nawo ahloliwe kule nqubo.Imishini yokuqala yokwakha eyisibonelo enalezi zinjini ibisebenza kusukela ngo-2021.
Ubuchwepheshe be-PFI: indawo yokuqala ekuthuthukisweni
Imizamo yokuqala yokwakhiwa kwenjini ye-hydrogen ithathe i-PFI njengobuchwepheshe bokuqala obufanele.Umshini wokuqala osebenza nge-ICE engu-100% ephehlwa yi-hydrogen yi-Liebherr R 9XX H2 crawler excavator.
Kuyo, injini engu-zero-emission 6-cylinder H966 ifeza izidingo ezithile ngokwamandla namandla.I-R 9XX H2 enenjini ye-H966 ekucushweni kwayo komjovo kaphethiloli echwebeni
izoboniswa ku-booth 809 – 810 naku-812 – 813. Eduze, i-H966 izokwethulwa lapho ku-InnoLab.
DI: isinyathelo esiya ezinjinini ze-hydrogen ezisebenzayo
Ekhuthazwe imiphumela ezuzwe ngobuchwepheshe be-PFI, u-Liebherr uqhubeka nokuphishekela imisebenzi yakhe yocwaningo nentuthuko emkhakheni we-DI.
I-prototype yenjini engu-4-cylinder H964 ekhonjiswe endaweni yezingxenye ze-326 ehholo A4 ifakwe ubuchwepheshe obushiwo.Kulokhu, i-hydrogen ijovwa ngqo ekamelweni elivuthayo, kuyilapho ngesisombululo se-PFI ivuthela endaweni yokungena emoyeni.
I-DI inikezela ngamathuba anyukile ngokuya ngokusebenza kahle komlilo kanye nokuminyana kwamandla, okwenza izinjini ze-hydrogen zibe enye indlela ekhangayo kunezinjini zikadizili uma kukhulunywa ngezinhlelo zokusebenza ezifuna kakhulu.
Yini elandelayo ezayo?
Ingxenye yezingxenye ilindele ukuqalisa uchungechunge lokukhiqizwa kwezinjini ze-hydrogen ngo-2025. Okwamanje, inkampani ibeka imisebenzi yayo yocwaningo ngomjovo kaphethiloli ukuze iqhubekisele phambili ukusha nokuqinisekisa ukuminyana kwamandla okukhulu.
Ngaphezu kwezinjini eziphehlwa yi-hydrogen engu-100%, imizamo eminingana yocwaningo endaweni yamanye amafutha iyaqhubeka.Isibonelo esisodwa injini kaphethiloli embaxambili engasebenza nge-hydrogen ebaswe ngomjovo we-HVO noma ngokugcwele ku-HVO.Lobu buchwepheshe buzovumela ukuguquguquka okwengeziwe ekusebenzeni kwemoto ngokucushwa okuhlukile.
Okuvelele:
Ingxenye yomkhiqizo we-Liebherr components yethula ama-prototypes okuqala ezinjini ezivuthayo ze-hydrogen, i-H964 ne-H966, e-Bauma yalo nyaka.
I-H966 prototype inika amandla isiseshi sokuqala sika-Liebherr esiqhutshwa yi-hydrogen
