Ukuthi ikusasa lemboni yezimoto lisezimotweni zikagesi (ibhethri noma i-fuel cell) ngokuya ngokuthula - umuntu ongazi kakhulu ongasho okuhlukile. Kodwa-ke, kule ndaba lapho imibono ivame ukuhlukana, ukucatshangelwa okufanayo kuyadingeka ekucatshangelweni okwenziwa ngekusasa lezinjini ezivuthayo.
Injini evuthayo ayikapheli, futhi kunezimpawu ezimbalwa ezibonisa lokho. Ake sikhumbule ezimbalwa nje:
- Wena amafutha okwenziwa , esesike sakhuluma ngayo, ingase ibe ngokoqobo;
- I-Mazda ihlala iqinile ku- ukuthuthukiswa kwenjini nobuchwepheshe ukuthi esikhathini esingeside esidlule kwakubonakala kungenakwenzeka ukukufaka ekukhiqizeni;
- Ngisho nabakwaNissan/Infiniti ababheja kakhulu ngezimoto zikagesi bakhombisile lokho kusekhona "ujusi" ongeziwe ongakhama kuwolintshi elidala okuyinjini yomlilo;
- IToyota inentsha 2.0 litre injini (ekhiqizwe ngobuningi) enerekhodi elisebenza kahle elishisayo elingu-40%
Izolo u-Bosch ushaye enye impama yamagilavu amhlophe - asangcolile kusukela ku-Dieselgate... ulithandile ihlaya? - kulabo abaphikelela ekuzameni ukungcwaba injini endala evuthayo. Umkhiqizo waseJalimane umemezele ngobukhazikhazi kanye nesimo "inguquko enkulu" ekukhiqizweni kwenjini kadizili..
Njengoba ubona, injini yomlilo yangaphakathi iyaphila futhi iyakhahlela. Futhi njengokungathi lezi zimpikiswano azanele, iNyuvesi yaseWisconsin-Madinson yathola obunye futhi ubuchwepheshe obukwazi ukuhlanganisa umjikelezo we-Otto (uphethiloli) noDizili (udizili) kanye kanye. Kubizwa nge-Reactivity Controlled Compression Ignition (RCCI).
Injini esebenzisa udizili nophethiloli… ngesikhathi esifanayo!
Uxolo ngesingeniso esihle, ake singene ezindabeni. Inyuvesi yaseWisconsin-Madison ithuthukise injini ye-RCCI ekwazi ukuzuza ukusebenza kahle kwezinga lokushisa okungama-60% - okungukuthi, u-60% kaphethiloli osetshenziswa injini uguqulwa ube yizisebenzi futhi awumoshi ngendlela yokushisa.Kufanele kuqashelwe ukuthi le miphumela ifinyelelwe ekuhlolweni kwaselabhorethri.
Kwabaningi, kwakucatshangwa ukuthi akunakwenzeka ukufinyelela amanani alo myalelo, kodwa futhi injini endala yomlilo yamangala.
Isebenza kanjani i-RCCI?
I-RCCI isebenzisa ama-injection amabili isilinda ngasinye ukuze ixube uphethiloli osabela kancane (uphethiloli) nophethiloli osabela kakhulu (udizili) egumbini elifanayo. Inqubo yokushiswa komlilo iyathakazelisa - ama-petrolheads awadingi okuningi ukuze athatheke.
Okokuqala, ingxube yomoya nophethiloli ijovwa ekamelweni elivuthayo, bese kufakwa idizili kuphela. Amafutha amabili ahlanganayo njengoba i-piston isondela endaweni ephezulu efile (PMS), ngaleso sikhathi kufakwa enye isamba esincane sikadizili, okubangela ukuthungela.
Lolu hlobo lokuvutha lugwema izindawo ezishisayo ngesikhathi somlilo — uma ungazi ukuthi "izindawo ezishisayo" ziyini, sichazile kulo mbhalo mayelana nezihlungi zezinhlayiya ezinjinini zikaphethiloli. Njengoba ingxube i-homogenized kakhulu, ukuqhuma kusebenza kahle futhi kuhlanzekile.
Okokugcina, u-Jason Fenske ovela ku-EngineeringExplained wenze ividiyo echaza yonke into, uma ungafuni ukuqonda izisekelo nje:
Ngalolu cwaningo oluvela eNyuvesi yaseWisconsin-Madison, lo mqondo wafakazelwa ukuthi uyasebenza, kodwa usadinga ukuthuthukiswa okwengeziwe ngaphambi kokuba ufinyelele ekukhiqizeni. Ngokwezinto ezibonakalayo, okuwukuphela kwe-drawback yisidingo sokugcwalisa imoto ngamafutha amabili ahlukene.
