Liebherr ga-ewepụta engines hydrogen prototype ya na Bauma 2022.
Na Bauma 2022, akụkụ ngwaahịa nke Liebherr na-ewebata ụdị abụọ nke injin hydrogen ya maka saịtị ihe owuwu echi.Ihe nlere nke ọ bụla na-eji teknụzụ injection hydrogen dị iche iche, injection ozugbo (DI) yana ntụtụ mmanụ ụgbọ mmiri (PFI).
N'ọdịniihu, injin ndị na-agba ọkụ agaghịzi enwe ike naanị site na dizel fosil.Iji nweta nnọpụiche ihu igwe n'afọ 2050, a ga-eji mmanụ ọkụ sitere na isi mmalite ike na-adigide.Green hydrogen bụ otu n'ime ha, ebe ọ bụ mmanụ carbon na-ekwe nkwa, nke na-adịghị eme ka ikuku CO2 ọ bụla na-ere ọkụ n'ime engine combustion (ICE).
Ọkachamara Liebherr na mmepe nke ICE ga-emekwa ka iwebata teknụzụ hydrogen ngwa ngwa n'ahịa.
Igwe mmiri hydrogen: ọdịnihu na-ekwe nkwa
Akụkụ ngwaahịa nke Liebherr etinyela nnukwu ego n'oge na-adịbeghị anya n'ime mmepe nke injin hydrogen na akụrụngwa nnwale ya.A nwalere engines prototype kemgbe 2020. Ka ọ dị ugbu a, prototypes egosila nsonaazụ na-agba ume n'ihe gbasara arụmọrụ na ikuku, ma na oche ule na n'ọhịa.
A na-enyochakwa teknụzụ ịgba mmiri na teknụzụ ọkụ dị iche iche, dị ka ntụtụ mmanụ ụgbọ mmiri (PFI) na injection ozugbo (DI), na usoro a.Igwe ihe owuwu nke mbụ nwere igwe ndị a na-arụ ọrụ kemgbe 2021.
Teknụzụ PFI: mmalite na mmepe
Mgbalị mbụ na mmepe nke injin hydrogen atụlewo PFI dị ka nkà na ụzụ mbụ kwesịrị ekwesị.Igwe mbụ na-eji ICE nwere mmanụ ọkụ 100% na-agba ọsọ bụ Liebherr R 9XX H2 crawler excavator.
N'ime ya, igwe efu 6-cylinder engine H966 na-emezu ihe a kapịrị ọnụ n'ihe gbasara ike na ike.R 9XX H2 nwere injin H966 na nhazi ntụtụ mmanụ ụgbọ mmiri ya
ga-egosipụta na ụlọ ntu 809 - 810 na 812 - 813. N'ebe dị nso, a ga-egosipụta H966 n'ebe ahụ na InnoLab.
DI: nzọụkwụ na-aga n'ihu igwe hydrogen dị mma
N'ịbụ onye na-agba ume site na nsonaazụ ndị e nwetara na nkà na ụzụ PFI, Liebherr na-aga n'ihu na-eme nchọpụta na mmepe mmepe na mpaghara DI.
Ihe nlere nke igwe 4-cylinder H964 gosipụtara n'ụlọ ntu components 326 dị n'ụlọ nzukọ A4 nwere teknụzụ kwuru.N'okwu a, a na-agbanye hydrogen ozugbo n'ime ụlọ combustion, ebe ngwọta PFI na-agbanye n'ọdụ ụgbọ mmiri ikuku.
DI na-enye ikike dị ukwuu n'ihe gbasara arụmọrụ combustion na njupụta ike, nke na-eme ka engines hydrogen bụrụ ihe na-adọrọ adọrọ na mmanụ dizel ma a bịa na ngwa ndị na-achọsi ike karị.
Gịnị na-esote na-abịa?
Akụkụ nke akụkụ ahụ na-atụ anya ịmalite mmepụta usoro nke engines hydrogen site na 2025. Ka ọ dị ugbu a, ụlọ ọrụ ahụ na-ewepụta ọrụ nyocha ya na mmanụ ụgbọala iji mee ka ọkụ dịkwuo mma na iji hụ na njupụta ike kachasị.
Na mgbakwunye na 100% mmanụ ọkụ hydrogen, ọtụtụ nyocha nyocha na mpaghara mmanụ ọkụ ọzọ na-aga n'ihu ugbu a.Otu ihe atụ bụ igwe mmanụ abụọ nwere ike ịgba ọsọ na hydrogen nke HVO na-agbanye ma ọ bụ zuru ezu na HVO.Nkà na ụzụ a ga-enye ohere maka mgbanwe ndị ọzọ na-arụ ọrụ ụgbọ ala na nhazi dị iche iche.
