Ngophuhliso olukhawulezayo lwezithuthi zamandla amatsha, iinjini zokutsha zangaphakathi zisondela ekuphelisweni. Izithuthi ze-Hybrid kunye nezithuthi zombane zineenzuzo ezininzi ekunciphiseni ukukhutshwa kunye nokunciphisa iindleko zokusebenza. Ukongeza kwiimoto zombane ezicocekileyo, ii-injini zisadlala indima ebalulekileyo kwi-plug-in hybrid kunye nezithuthi zoluhlu olwandisiweyo.
I-Subaru ifake isicelo selungelo elilodwa lomenzi wechiza kwindlela esebenza kakuhle yokutshisa kwangaphambili. IPorsche okwangoku iphonononga ezo nkqubo zokwandisa amandla. Nangona kunjalo, i-Subaru ayijongi amandla ngokwawo, kodwa ukusebenza kakuhle. I-patent ikakhulu isombulula ingxaki yokuqalisa okubandayo kwe-injini.
Njengoko sonke sisazi, ukuze isiguquli sendlela-ntathu sisebenze ngokukhawuleza ukukhupha ukukhutshwa ngexesha elibandayo, isantya se-injini siya kuba phezulu kunesiqingatha sesantya esiqhelekileyo sokungenzi nto, kwaye siya kugcinwa phakathi kwe-1500 kunye ne-1800 rpm. Ukongezelela, xa injini iyancipha ngokukhawuleza ngexesha lokuqhuba ngokuqhelekileyo, i-fuel ayikwazi ukutshiswa ngokupheleleyo kwaye iya kubambelela eludongeni lwegumbi lokutsha. Ezi meko ziya kwandisa ukuxinana kwamafutha kwaye zenze inkqubo yokutsha ye-injini ikhuphe ii-hydrocarbons eziyingozi ngakumbi. Ilungelo elilodwa lomenzi wechiza langaphambili elisetyenziswa yi-Subaru yindlela yokusombulula ingxaki yenkunkuma yamafutha kunye nokukhutshwa kwezinto ezikhutshwayo okwandisiweyo ngexesha lokuqala kwengqele yemveli.
Ukutsha kwangaphambili akusiyo iteknoloji entsha, kodwa ayifane isetyenziswe kwiimoto eziqhelekileyo. Ngenxa yokuba, nokuba isetyenziswe, ubukhulu becala ayaziwa kuluntu. Kwi-injini yokutshisa yangaphakathi yendabuko, umxube we-fuel-air ophunyezwe yi-injector kunye ne-valve yokungena iyatshiswa kwigumbi eliphambili lokutshisa ngeplagi ye-spark. Itekhnoloji yokutsha kwangaphambili isebenzisa iqokobhe le-hemispherical ejikeleze i-spark plug ukwenza igumbi lokutsha elahlukileyo apho kunokutsha kwangaphambili.
Inkqubo yokutsha yangaphambili isebenzisa isixhobo esincinci sokutshisa kwigumbi lokutshisa elahlukileyo ukuze ikhuphe ilangatye kwaye ikhanyise ifutha kwigumbi eliphambili lokutsha. Le yenye inkqubo yokutshisa ikhulisa umgangatho wokutsha ngokubanzi, ivumela umjikelo we-injini ngokucokisekileyo kunye nokunciphisa inkunkuma, ngakumbi ngexesha lengqele yokuqala apho amafutha amaninzi atshiswa ngesantya esisezantsi. Igumbi lokutsha langaphambili linendawo esembindini/engundoqo kunye nezimbini ezincinci kwimingxunya emacaleni omabini, ukuvuleka kunye nemingxuma ilungiselelwe ukuqondisa umoya ukusuka kwigumbi lokutshisa ngaphambili kwivalve yomoya yoxinzelelo oluphezulu, kunye nokwalathisa intlantsi evutha umlilo.

I-valve yoxinzelelo lomoya enikezela umoya kwi-pre-chamber isebenza njengekhaka ngexesha lokuqalisa, ijikeleze i-pre-igumbi kunye nomgangatho womoya, ukuthintela umxube we-fuel ukuba unamathele ngaphandle kwegumbi langaphambili, ngelixa liququzelela ukutshisa ngokufanelekileyo umxube we-fuel / air ngaphakathi kwegumbi langaphambili. Ngethuba lokuqalisa, i-injector yomoya iyasebenza kuqala, ilandelwa yi-injector ye-fuel, idala i-"swirl" isiphumo ngaphakathi kwegumbi lokutsha, kunye nenaliti ezimbini ezidlulayo ngexesha.
Itekhnoloji ayizi kuzisa iinjini zokutsha zangaphakathi kumanqanaba okusebenza kwe-hybrid okanye izithuthi zombane, kodwa zinokukhokelela kwizinto ezintsha ezitsha.
