ULiebherr uza kudlala iinjini zakhe zokuqala ze-hydrogen eBauma ngo-2022.
E-Bauma 2022, icandelo lemveliso ye-Liebherr lizisa iiprototypes ezimbini ze-injini yayo ye-hydrogen kwiziza zokwakha zangomso.Umzobo ngamnye usebenzisa itekhnoloji yesitofu se-hydrogen eyahlukeneyo, inaliti ethe ngqo (DI) kunye ne-port fuel injection (PFI).
Kwixesha elizayo, ii-injini zokutsha azisayi kusetyenziswa kuphela nge-diesel yefosili.Ukuze ufezekise ukungathathi hlangothi kwemozulu ngo-2050, amafutha avela kwimithombo yamandla ezinzileyo kuya kufuneka asetyenziswe.Ihydrogen eluhlaza yenye yazo, kuba isisibaso esithembisayo esingenakhabhoni, esingabangeli nakuphi na ukukhutshwa kweCO2 ngelixa kuvutha ngaphakathi kwinjini yokutsha yangaphakathi (ICE).
Ubuchwephesha bukaLiebherr kuphuhliso lwee-ICE buya kuqhuba ngakumbi ukwazisa ngokukhawuleza kobuchwepheshe be-hydrogen kwintengiso.
Iinjini zeHydrojeni: ikamva elithembisayo
Icandelo lemveliso yamacandelo e-Liebherr kutshanje lenze utyalo-mali olubalulekileyo kuphuhliso lwe-injini ye-hydrogen kunye nezixhobo zovavanyo.Iinjini zePrototype ziye zavavanywa ukususela ngo-2020. Okwangoku, iiprototypes zibonise iziphumo ezikhuthazayo ngokubhekiselele ekusebenzeni kunye nokukhutshwa, zombini kwiibhentshi zokuvavanya nakwintsimi.
Iinaliti ezahlukeneyo kunye nobuchwephesha bokutsha, obufana ne-port fuel injection (PFI) kunye nenaliti ethe ngqo (DI), nazo ziye zavavanywa kwinkqubo.Oomatshini bokuqala bokwakha abaxhotyiswe ngezi njini bebeqhuba ukusukela ngo-2021.
Itekhnoloji yePFI: indawo yokuqala kuphuhliso
Imizamo yokuqala ekuphuhliseni injini ye-hydrogen ithathele ingqalelo i-PFI njengeteknoloji efanelekileyo yokuqala.Umatshini wokuqala osebenza nge-100% ye-hydrogen-fuelled ICE yi-Liebherr R 9XX H2 i-crawler excavator.
Kuyo, i-zero-emission 6-cylinder injini H966 izalisekisa iimfuno ezithile ngokwamandla kunye namandla.I-R 9XX H2 kunye ne-injini ye-H966 kwi-port yayo yokumisela inaliti yamafutha
iya kuboniswa kwi-booth 809 - 810 kunye ne-812 - 813. Kufutshane, i-H966 iya kuboniswa apho kwi-InnoLab.
DI: inyathelo eliya kwiinjini zehydrogen ezisebenzayo
Ekhuthazwe ziziphumo eziphunyeziweyo ngetekhnoloji yePFI, uLiebherr uqhubela phambili nokulandela uphando kunye nemisebenzi yophuhliso kwicandelo le-DI.
Injini ye-4-cylinder prototype ye-H964 eboniswe kwindawo yecandelo le-326 kwiholo ye-A4 ixhotyiswe ngobuchwepheshe obuxeliweyo.Kule meko, i-hydrogen ifakwe ngokuthe ngqo kwigumbi lokutsha, ngelixa isisombululo se-PFI sivuthelwa kwi-port yokungenisa umoya.
I-DI ibonelela ngesakhono esongeziweyo malunga nokusebenza kakuhle kunye noxinaniso lwamandla, okwenza iinjini zehydrogen zibe yeyona ndlela inomtsalane kwiinjini zedizili xa kufikwa kwizicelo ezifuna kakhulu.
Yintoni elandelayo ezayo?
Icandelo lamacandelo lilindele ukuqalisa ukuveliswa kweenjini ze-hydrogen ngo-2025. Okwangoku, inkampani ibeka imisebenzi yayo yophando kwinaliti yamafutha ukuqhubela phambili ukutshisa kunye nokuqinisekisa ukuxinwa kwamandla aphezulu.
Ukongeza kwi-100% yeenjini ze-hydrogen-fuelled, iinzame ezininzi zophando kwindawo yamafutha angamanye ziyaqhubeka.Omnye umzekelo yinjini yamafutha amabini enokuthi isebenze kwi-hydrogen evuthayo ngenaliti ye-HVO okanye ngokupheleleyo kwi-HVO.Le teknoloji iya kuvumela ukuguquguquka ngakumbi ekusebenzeni kwesithuthi kunye nokucwangciswa okuhlukeneyo.
Amagqabantshintshi:
Icandelo lemveliso yeLiebherr lazisa iiprototypes zokuqala zeenjini zokutsha ze-hydrogen, i-H964 kunye ne-H966, kwi-Bauma yalo nyaka.
Iprototype ye-H966 inika amandla i-Liebherr yokuqala eqhutywa yi-hydrogen.
