Nyowani rehydrogen peji reBMW

Bavaria kambani iri kugadzirira diki X5 ine mafuta maseru

BMW ndiyo inonyanya kumhanya kambani mune iyo hydrogen hupfumi. Iyo kambani yanga ichigadzira injini dzehydrogen kupisa makore apfuura. Iye zvino imwe pfungwa iri kuitika.

Kufamba kwemagetsi kunogona kusimuka, asi iine nuances ayo. Kunze kwekunge, chokwadi, isu tichifungidzira kuti hydrogen mafuta maseru mota ari mune iri boka. Izvi zvinonzwisisika, zvichipiwa chokwadi chekuti sero riri kutaurwa rinogadzira magetsi zvichibva mukubatanidzwa kwehydrogen uye okisijeni mune chigadzirwa chemakemikari, uye inoshandiswa kumisikidza mota yemagetsi inotyaira mota. Volkswagen Boka rine rakasimba zano rekusimudzira yerudzi urwu rwetekinoroji uye rakapihwa kukudziridzwa kwevainjiniya veAudi.

Toyota, iyo iri kugadzirira Mirai nyowani, pamwe neHyundai neHonda, iri kunyanya kushingaira muchiitiko ichi. Mukati meboka rePSA, Opel inoona nezvekuvandudzwa kwehydrogen cell matekinoroji, ayo ane makumi emakore echiitiko mundima iyi senge tekinoroji yeGeneral Motors.

Mota dzakadai hadziwanzo kuve dzakajairika mumigwagwa yeEurope, asi tarisiro yacho zvakadaro inofungidzirwa zvichipa chokwadi chekuti mapurazi emhepo emunharaunda anogona kuvakwa kuti agadzire magetsi nehydrogen kubva mumvura nekupa mahydrogen zvinomera. Masero emafuta ari chikamu cheiyo equation iyo inobvumira iro rakawandisa simba kuti rishandurwe kuti riunze magetsi kubva kunovandudzwa sosi kuenda kuhydrogen uye kudzokera kusimba, ndiko kuti, kwekuchengetedza.

Kuburikidza nekudyidzana neToyota, BMW inogona zvakare kuvimba nekuvapo mumusika uyu mudiki niche. Gore nehafu mushure mekuratidzwa kweBMW I-Hydrogen Inotevera muFrankfurt, BMW yakapa rumwe ruzivo nezve mota iri padyo neyakatevedzana kugadzirwa - panguva ino zvichibva pane yazvino X5. Kwemakore, BMW yanga ichiratidza hydrogen mota prototypes inoshandisa hydrogen sehuni yeinjini dzinopisa mukati. Iyo hydrogen sero ndiyo yakanakisa mhinduro maererano nekubudirira, asi mainjiniya eBMW akawana ruzivo rwakakosha mumunda wekupisa maitiro emafuta asina kabhoni mumamorekuru avo. Zvisinei, iyi inyaya yakasiyana.

Kusiyana nemudiwa Toyota, iyo ichakurumidza kuvhura yechipiri-chizvarwa Mirai yakavakirwa paTNGA modular system, BMW inonyanya kungwarira munzvimbo ino. Naizvozvo, iyo itsva I-NEXT inoratidzwa kwete semotokari yekugadzira, asi semota diki yakatevedzana iyo ichaunzwa kune vashoma vakasarudzwa vatengi. Tsananguro yeizvi iri mune zvisingakoshi zvivakwa. "Semaonero edu, sesimba remagetsi, hydrogen inofanira kutanga kugadzirwa muhuwandu hwakakwana uye nerubatsiro rwegirinhi simba, uye zvakare kuwana yemakwikwi mitengo. Injini dzemafuta edzimotokari dzichashandiswa mumotokari dzinonetsa kuisa magetsi panguva ino, semarori anorema, "akadaro Klaus Fröhlich, nhengo yebhodhi revatungamiriri veBMW AG uye ane basa rekutsvaga nekusimudzira.

Bhatiri uye mafuta sero mune symbiosis

Nekudaro, BMW yakazvipira kune yakajeka hydrogen zano kwenguva refu. Ichi chikamu chehurongwa hwekambani hwese hwekugadzira akasiyana emagetsi emagetsi, kwete emota dzinofambiswa nemabhatiri chete. "Tine chokwadi chekuti munguva pfupi iri kutevera kuchave nemhando dzakasiyana dzekufamba, sezvo pasina mhinduro imwe chete inozadzisa zvese zvinodiwa zvevatengi. Tinotenda kuti hydrogen sehuni ichava mbiru yechina mune yedu powertrain portfolio munguva refu, "anowedzera Fröhlich.

PaI-Hydrogen Inotevera, BMW inoshandisa tekinoroji mhinduro dzakagadzirwa mukubatana neindasitiri-inotungamira Toyota. Iwo makambani maviri anga achidyidzana munzvimbo ino kubvira 2013. Pasi pevhavha yekumberi yeX5 pane murwi wemafuta maseru anogadzira magetsi nekuita pakati pehydrogen neoksijeni (kubva mumhepo). Simba rekuburitsa rinogoneswa nechinhu icho i125 kW. Iyo peturu sero pasuru ikambani yeBavaria inosimudzira, yakafanana neyayo gadzira bhatiri (ine lithiamu-ion maseru kubva kune vanotengesa seSamsung SDI), uye maseru iwo pachawo akabatanidzwa pamwe neToyota.

Iyo hydrogen inochengetwa mumatangi maviri akanyanya (700 bar) matangi. Maitiro ekuchaja anotora maminetsi mana, unova mukana wakakosha pamusoro pemotokari dzinoshandiswa nebhatiri. Iyo sisitimu inoshandisa iyo lithium-ion bhatiri sechinhu chebhuku, ichipa zvese zviri zviviri kupora panguva yekumisa brake uye simba muyero uye, nekudaro, rubatsiro panguva yekumhanyisa. Panyaya iyi, iyo sisitimu yakafanana nemotokari yakasanganiswa. Zvese izvi zvinodikanwa nekuti mukuita bhatiri simba rekuburitsa rakakura kudarika iro remafuta esero, kureva kuti, kana iyo yekupedzisira ichikwanisa kuitakura yakazara mutoro, bhatiri rinogona kupa yakakwira kuburitsa simba uye system system ye374 hp panguva yepamusoro mutoro. Iyo yemagetsi inotyaira pachayo ndiyo yazvino yechishanu-chizvarwa BMW uye ichatanga kuita muBMW iX3.

Muna 2015, BMW yakafumura mota yehydrogen mota yakatarwa neBMW 5 GT, asi mukuita, I-Hydrogen Inotevera ichavhura peji nyowani yehydrogen yechiratidzo. Ichatanga neakateedzana mudiki muna 2022, iine mahombe akateedzana anotarisirwa muhafu yepiri yemakore gumi.
