Liebherr achatangisa injini dzayo dzehydrogen prototype kuBauma 2022.
PaBauma 2022, iyo Liebherr components chigadzirwa chikamu chiri kuunza maviri prototypes einjini yayo yehydrogen yenzvimbo dzekuvaka mangwana.Imwe neimwe prototype inoshandisa akasiyana hydrogen jekiseni matekinoroji, jekiseni rakananga (DI) uye jekiseni remafuta echiteshi (PFI).
Mune ramangwana, injini dzinopisa hadzichashandiswi chete nefossil diesel.Kuti uwane kusarerekera kwemamiriro ekunze panosvika 2050, mafuta emagetsi anobva kune inogoneka magetsi anozofanirwa kushandiswa.Green hydrogen ndeimwe yayo, sezvo iri vimbiso isina kabhoni-isina mafuta, isingakonzere chero CO2 emissions ichitsva mukati meinjini yekupisa yemukati (ICE).
Hunyanzvi hwaLiebherr mukuvandudza maICEs huchafambisawo kukurumidza kuunzwa kwehydrogen tekinoroji kumusika.
Injini dzeHydrogen: ramangwana rinovimbisa
Iyo Liebherr zvikamu zvechigadzirwa chikamu ichangobva kuita yakakosha mari mukuvandudza kwayo hydrogen injini uye bvunzo zvivakwa.Prototype injini dzakaedzwa kubvira 2020. Zvichakadaro, iyo prototypes yakaratidza mhedzisiro inokurudzira maererano nekuita uye kuburitsa, zvese pamabhenji ebvunzo uye mumunda.
Yakasiyana jekiseni uye tekinoroji yekupisa, senge port mafuta jekiseni (PFI) uye yakananga jekiseni (DI), yakaongororwawo mukuita.Michina yekutanga yekuvaka prototype ine injini idzi yanga ichimhanya kubvira 2021.
PFI tekinoroji: nzvimbo yekutanga mukusimudzira
Kwekutanga kuedza mukugadzirwa kweinjini yehydrogen vakafunga PFI seyekutanga yakakodzera tekinoroji.Muchina wekutanga unoshanda ne100% hydrogen-fuelled ICE ndiyo Liebherr R 9XX H2 crawler excavator.
Mariri, iyo zero-emission 6-cylinder injini H966 inozadzisa izvo zvinodiwa maererano nesimba uye simba.Iyo R 9XX H2 ine H966 injini mune yayo chiteshi mafuta jekiseni kumisikidzwa
ichave ichiratidzwa pa booth 809 - 810 uye 812 - 813. Padhuze, iyo H966 ichaunzwa imomo muInnoLab.
DI: nhanho yekuenda kune inoshanda mahydrogen injini
Achikurudzirwa nemhedzisiro yakawanikwa neiyo PFI tekinoroji, Liebherr anoenderera mberi nekuita zvekutsvaga nekusimudzira zviitiko mumunda weDI.
Iyo 4-cylinder injini prototype H964 inoratidzwa pane zvikamu 'dumba 326 muhoro A4 ine yakashongedzwa tekinoroji.Muchiitiko ichi, hydrogen inobaiwa yakananga mukamuri yekupisa, nepo nePFI mhinduro inopeperetswa muchiteshi chemhepo.
Iyo DI inopa yakawedzera kugona maererano nekubatidza kunyatsoita uye simba density, izvo zvinoita kuti injini dzehydrogen ive inoyevedza imwe nzira kune injini dzedhiziri kana zvasvika kune zvakanyanya kudiwa maapplication.
Chii chinotevera kuuya?
Chikamu chezvikamu chinotarisira kutanga kugadzirwa kweinjini dzehydrogen panosvika 2025. Zvichakadaro, kambani inotangisa mabasa ayo ekutsvagisa mujekiseni remafuta kuti iwedzere kuwedzera kupisa uye kuve nechokwadi chekuwanda kwesimba.
Pamusoro pe100% hydrogen-fuelled engines, akati wandei tsvakurudzo kuedza munzvimbo yemamwe mafuta arikuenderera mberi.Mumwe muenzaniso injini yemafuta maviri inokwanisa kumhanya pahydrogen yakabatidzwa nejekiseni reHVO kana zvizere paHVO.Iyi tekinoroji inobvumira kuchinjika kwakawanda mukushanda kwemotokari nemaitiro akasiyana.
Zvinonyanya kukosha:
Iyo Liebherr zvikamu zvechigadzirwa chikamu chinounza yekutanga prototypes yeinjini yekupisa yehydrogen, iyo H964 uye H966, paBauma yegore rino.
Iyo H966 prototype inopa simba Liebherr yekutanga hydrogen-inotyairwa inokambaira yekuchera.
