Ukuba ikamva loshishino lweemoto lilele kwizithuthi zombane (ibhetri okanye i-fuel cell) liya lisiba noxolo - kuphela umntu ongaziyo unokuthi ngenye indlela. Nangona kunjalo, kulo mba apho izimvo zidla ngokuhlukana, kufuneka kuqwalaselwe okufanayo kwiingcamango ezenziwayo malunga nekamva leenjini zokutsha.
Injini yokutsha ayikapheli, kwaye kukho imiqondiso emininzi kuloo nto. Masikhumbule nje ezimbalwa:
- Wena Amafutha okwenziwa , esele sithethe ngayo, inokuba yinto yokwenene;
- I-Mazda ihlala iqinile kwi injini kunye nophuhliso lobuchwephesha ukuba kungekudalanga kudala kwabonakala kungenakwenzeka ukuba kufakwe kwimveliso;
- KwaNissan/Infiniti, ababheja kakhulu kwiimoto zombane, bayibonisile loo nto kusekho "ijusi" eninzi ekufuneka icudiswe kwiorenji endala eyinjini yokutsha;
- IToyota inento entsha 2.0 ilitha injini (iveliswe ngobuninzi) kunye nerekhodi esebenzayo ye-thermal ye-40%
Izolo uBosch wenze enye impama yeeglavu ezimhlophe - isemdaka kwi-Dieselgate… ubuwuthandile lo mqhulo? - kwabo banyanzelisa ukuzama ukungcwaba injini endala yokutsha. I-brand yaseJamani yabhengeza ngobukhazikhazi kunye neemeko "i-mega-revolution" kukukhutshwa kwe-injini ye-diesel..
Njengoko ubona, injini yokutshisa yangaphakathi iyaphila kwaye iyakhaba. Kwaye ngokungathi ezi ngxoxo azanele, iYunivesithi yaseWisconsin-Madinson yafumanisa obunye ubuchwephesha obukwaziyo ukudibanisa imijikelo ye-Otto (petroli) kunye neDizili (idizili) ngaxeshanye. Ibizwa ngokuba yiReactivity Controlled Compression Ignition (RCCI).
Injini esebenzisa idizili kunye nepetroli… ngaxeshanye!
Uxolo ngentshayelelo enkulu, masingene ezindabeni. IYunivesithi yaseWisconsin-Madison iphuhlise i-injini ye-RCCI ekwazi ukuphumeza ukusebenza kakuhle kwe-thermal ye-60% - oko kukuthi, i-60% yamafutha asetyenziswa yi-injini iguqulwa ibe yimisebenzi kwaye ayichithwanga ngendlela yobushushu.Kufuneka kuqatshelwe ukuba ezi ziphumo zaphunyezwa kwiimvavanyo zaselabhoratri.
Kwabaninzi, kwakucingwa ukuba akunakwenzeka ukufikelela kumaxabiso alo myalelo, kodwa kwakhona injini yokutsha endala yamangaliswa.
Isebenza njani iRCCI?
I-RCCI isebenzisa ii-injection ezimbini nge-cylinder ukuxuba i-fuel ephantsi (i-petroli) kunye ne-fuel-reacting fuel (diesel) kwigumbi elifanayo. Inkqubo yokutshisa inika umdla - iintloko zepetroli azifuni kakhulu ukuba zibe nomdla.
Okokuqala, umxube womoya kunye nepetroli utofwa kwigumbi lokutsha, kwaye emva koko kufakwe idizili. Amafutha amabini adibanisa njengoko i-piston isondela kwiziko eliphezulu lokufa (PMS), apho elinye ixabiso elincinci le-diesel lifakwe, elibangela ukuvutha.
Olu hlobo lokutshisa luthintela iindawo ezishushu ngexesha lokutsha - ukuba awuyazi ukuba zeziphi "iindawo ezitshisayo", siye sachaza kulo mbhalo malunga nezihluzo ze-particulate kwiinjini zepetroli. Njengoko umxube une-homogenized kakhulu, ukuqhuma kusebenza kakuhle kwaye kucoceke.
Kwirekhodi, uJason Fenske ovela kwi-EngineeringExplained wenze ividiyo echaza yonke into, ukuba awufuni ukuqonda izinto ezisisiseko:
Ngolu phononongo oluvela kwiYunivesithi yaseWisconsin-Madison, lo mbono wangqinwa ukuba usebenza, kodwa usafuna uphuhliso olongezelelweyo ngaphambi kokuba ufikelele kwimveliso. Ngokwezinto eziphathekayo, i-drawback kuphela iyimfuneko yokunyusa imoto ngamafutha amabini ahlukeneyo.
