GDI injini
Imwe yenzira dzekuvandudza kushanda kweinjini yekupisa yemukati uye kuderedza kuburitswa kwezvinhu zvine chepfu ndeyekugonesa nzira yekupisa yemusanganiswa mumasilinda.
Nzira yekuzadzisa chinangwa ichi ndeyekugadzirira nemazvo musanganiswa unopisa uchishandisa jekiseni repeturu. Izvo zvakajairika kushandisa imwechete uye yakawanda-chiteshi jekiseni remafuta mune yakawanda yekudyara, asi chete kwemakore maviri chete mota-yakagadzirwa yakawanda inofambiswa neinjini yekudzima moto, ichimhanya papeturu inobaiwa yakananga mumasilinda pasi pekumanikidza kwakanyanya GDI. (peturu ine jekiseni rakananga), mumugwagwa kwemakore makumi maviri. Mukana usina kupokana wemota iyi kuderera kwemafuta, kuyerwa neiyo nyowani yeEurope kutenderera. Kuchengetedza kunogona kusvika ku2%. zvichienzaniswa neakajairika injini. Injini iyi inoshandisa mhepo yakapfava/mafuta musanganiswa muchikamu chekutakura. Kupisa kwemusanganiswa wakadaro kunogoneka nekuda kwechimiro chakakosha chekamuri yekupisa, umo nzvimbo yemusanganiswa wakapfuma, unopisa zvakanyanya unogadzirwa pedyo ne spark plug. Kubva pairi, murazvo unopararira kunzvimbo dzemusanganiswa wakaonda.
Kana simba rakazara richidiwa, injini inopisa musanganiswa wemhepo-mafuta ane lambda inokosha ye 1. Nguva yekutanga jekiseni inobvumira kusanganiswa kwehomogeneous kuumbwa, kupisa izvo zvisiri dambudziko.
GDI injini dzine imwe mukana pane dzakajairwa injini. Izvi zvakaderedzwa kabhoni dhaibhoni emissions uye yakaderera kusanganiswa kwenitrogen oxides kana injini iri kushanda pane zvishoma.
Kuzadza kwakananga kwejini ne-high-pressure peturu, inozivikanwa kwemakore makumi matanhatu, yakangoitwa, sezvo yakagadzira matambudziko mazhinji ehunyanzvi kune vanogadzira (mafuta haana zvivakwa zvekuzora).
Mota yekutanga yekugadzira ine injini yeGDI yakaunzwa neMitsubishi, Toyota iri padyo nekubudirira kweToyota, uye mugadziri weEuropean jekiseni masisitimu Bosch akagadzira GDI simba system ine control module, uye pamwe ichaenda kumotokari kubva. mubatanidzwa wekare?
