Injini ye-GDI

Enye yezindlela zokuthuthukisa ukusebenza kahle kwenjini evuthayo yangaphakathi kanye nokunciphisa ukukhishwa kwezinto ezinobuthi ukwenza ngcono inqubo yokuvutha kwengxube kumasilinda.

Indlela yokufeza lo mgomo ukulungisa ngokunembile ingxube evuthayo usebenzisa umjovo kaphethiloli. Kujwayeleke ngokwanele ukusebenzisa umjovo kaphethiloli owodwa kanye nonamachweba amaningi endaweni eningi esetshenziswayo, kodwa kuphela iminyaka emi-2 okuwukuphela kwemoto ekhiqizwe ngobuningi enikwa amandla yinjini ekhipha inhlansi egijima ngophethiloli efakwa ngqo kumasilinda ngaphansi kwengcindezi ephezulu ye-GDI. (uphethiloli onomjovo oqondile), emgwaqweni iminyaka engu-20. Inzuzo engangabazeki yale moto ukusetshenziswa kukaphethiloli okuphansi, kukalwa ngomjikelezo omusha waseYurophu. Ukonga kungafika ku-XNUMX%. uma kuqhathaniswa nezinjini ezijwayelekile. Le njini isebenzisa umoya omncane/uphethiloli othambile ebangeni lomthwalo oyingxenye. Ukushiswa kwengxube enjalo kungenzeka ngenxa yesimo esikhethekile segumbi elivuthayo, lapho indawo yengxube ecebile, evutha kakhulu yenziwa eduze kwepulaki ye-spark. Kusuka kuwo, ilangabi lisakazeka ezindaweni zengxube ethambile.

Uma amandla aphelele edingeka, injini ishisa ingxube ye-air-fuel enenani le-lambda engu-1. Isikhathi sokujova sangaphambi kwesikhathi sivumela ingxube ye-homogeneous ukuba yakheke, ukuvutha kwayo akuyona inkinga.

Izinjini ze-GDI zinenye inzuzo ngaphezu kwezinjini ezivamile. Lokhu ukukhishwa kwe-carbon dioxide encishisiwe kanye nokuhlushwa okuphansi kwe-nitrogen oxides lapho injini isebenza ngokwengxenye yemithwalo.

I-refueling eqondile yenjini ene-high-pressure petroli, eyaziwa iminyaka engu-60, isanda kuqaliswa, njengoba idale izinkinga eziningi zobuchwepheshe kubaklami (uphethiloli awunazo izakhiwo zokugcoba).

Imoto yokuqala yokukhiqiza enenjini ye-GDI yethulwa ngabakwaMitsubishi, iToyota isondele kakhulu empumelelweni yeToyota, futhi umkhiqizi waseYurophu wezinhlelo zomjovo uBosch usungule uhlelo lwamandla e-GDI olunemojula yokulawula, futhi mhlawumbe luzoya ezimotweni ezivela. isiqephu esidala?
