Iinjini zepetroli zanamhlanje zisebenza ngokufanelekileyo ngokushushu kwe-40% (uninzi, nangona kunjalo, zipesenti ezininzi zeepesenti ezingezantsi), kodwa iNissan ithi ine-prototype ye-injini yokutsha yepetroli yangaphakathi ekwazi ukufikelela kwi-50% , ixabiso elingaphezulu kunelo leenjini ze-Diesel. (eziphakathi kwama-43-45%).
Ukuba nomgangatho ophezulu wokusebenza kakuhle kwe-thermal - ukuthatha inzuzo yokuguqulwa kwamandla okushisa ukusuka kwi-chemical reaction of conbustion ibe yi-mechanical energy - kubalulekile ukunciphisa ukusetyenziswa kwe-CO2 / ukukhutshwa. Nangona kunjalo, ukuphumeza eli xabiso liphezulu le-50% yokusebenza kakuhle, i-Nissan yatshintsha injongo ye-injini yokutsha.
Le njongo intsha ayisasebenzi njengepropellant yesithuthi (apho idityaniswe namavili) kwaye ngoku isebenza kuphela njengejenereyitha (engaqhagamshelwanga kumavili) yamandla enjini yokutsala umbane.
I-injini yepetroli esebenza ngokufanelekileyo yokunikezela… ezombane
Akumangalisi ke ngoko, ukuba esi sibhengezo sifike phantsi kobuchwephesha be-Nissan's e-POWER (iteknoloji ye-hybrid), esele ikhonza imodeli efana neNqaku kwaye iya kukhonza isizukulwana sesithathu iNissan Qashqai.Njengoko sele sikhankanyile kumatyeli aliqela, iimodeli ze-e-POWER zikaNissan zizithuthi zombane. Nangona kunjalo, amandla ombane abawadingayo ukuze basebenze awaveli kwibhetri enkulu, enzima kunye nexabiso eliphezulu, kodwa kwi-injini yokutsha yangaphakathi ethatha indima yejenereyitha. Kusekho ibhetri, yinyani, kodwa incinci kakhulu, ikhonza ukugcina amandla aveliswa yi-injini yokushisa.
STARC, injini yomfuziselo
Ukuba yijeneretha nje, kunokwenzeka ukunciphisa ukusebenza kwe-injini yobushushu kulawulo lwayo olusebenzayo lokujikeleza kunye nemithwalo. Linyathelo lokuqala ekufezekiseni i-50% ukusebenza kakuhle kwe-thermal. I-Nissan ngoku ibonisa amanyathelo alandelayo okuphumeza loo njongo ibhongo, phantsi kophuhliso lwesizukulwana esilandelayo setekhnoloji ye-e-POWER, sele ibangele injini yeprototype, i-STARC.
Bhalisa kwincwadana yethu
I-STARC sisishunqulelo segama elithi "ijelo eliqinileyo, eliwayo neliluliweyo ngokufanelekileyo" - nangale nkcazo, besilahlekelwe ngandlel' ithile... NgokukaNissan, singayiguqulela ngokukhululekileyo le nto kwinto efana "negumbi eliqinileyo, eliyilwe ngokukodwa kunye negumbi lokutshisa elongeziweyo. ” .
Ukucacisa intsingiselo yako konke oku, umsebenzi weenjineli zakwaNissan ugxile ekukhawuleziseni ukuhamba komxube we-fuel-air ngaphakathi kwi-cylinder ngexesha lomlilo, oya kuvumela ukutsha okupheleleyo komxube wamafutha. ngomlinganiselo ophezulu woxinzelelo.
Into engazange ikwazi ukufezekiswa kwi-injini yokushisa esetyenziswa njenge-propeller. Kufuneka iphendule kwiinguqu eziqhubekayo zomthwalo kunye namandla kumzuzu ngamnye (ukukhawuleza, ukuhla, ukuthambekela), okudinga ukulungelelaniswa kwiiparamitha zayo zokusebenza (ukuhamba komxube kwi-cylinder, ixesha lokucima kunye nomlinganiselo wokunyanzeliswa). Ngaloo ndlela ukusebenza kwayo kuphazamisekile.
Yonke le miqobo iyanyamalala xa i-injini yobushushu iba yijenereyitha, apho iqala ukusebenza kuphela kwindlela efanelekileyo yokujikeleza kunye nolawulo lomthwalo, apho lusebenza khona ngakumbi (kuluhlu olulinganiselwe kakhulu), luvumela, ukususela ekuqaleni, ukusetyenziswa okuphantsi kunye izinto ezikhutshwayo.
Iziphumo zovavanyo lokuqala lophuhliso kwi-injini ye-multi-cylinder ziyathembisa. Ukusebenza kakuhle kwe-43% kuye kwafikelelwa xa kusetyenziswa i-EGR (ivalve yokukhupha igesi ejikelezayo) indlela yokudilution kunye ne-46% ngokufaka umxube obhityileyo wamafutha omoya (oko kukuthi ngomxube apho kukho umoya ongaphezulu kunezibaso ngokunxulumene nomxube ofanelekileyo ukutshiswa ngokupheleleyo kwamafutha).
I-50% ye-thermal esebenzayo ye-injini entsha ye-STARC iphunyeziwe xa la manyathelo edityaniswe nobuchwepheshe bokubuyisela ubushushu benkunkuma kunye ne-injini esebenza ngokuqhubekayo kunye nokujikeleza. Ngoku kushiyeke ukuba kulinde ixesha elingakumbi lokuziswa kwale njini yobushushu ikhethekileyo.
UToshihiro Hirai, uSekela Mongameli oMkhulu, iCandelo lobuNjineli beMoto yoMbane kunye ne-Powerplants e-Nissan Motor Co. Ltd“Ngeenjongo zokufezekisa ukungathathi hlangothi kwekhabhoni kumjikelo wobomi beemveliso zabo kude kube ngu-2050, uNissan ujonge ukufaka umbane ekuqaleni kweminyaka yoo-2030 zonke iimodeli ezintsha eziqaliswe kwiimarike eziphambili zehlabathi. Isicwangciso sombane se-Nissan sikhuthaza ukuphuhliswa kwamandla ombane kunye neebhetri ezisebenza kakhulu kwiimoto zombane, kunye ne-teknoloji ye-e-POWER emele intsika ebalulekileyo yeqhinga kule ndlela".
