New Injector Nozzle Dlla147s071 yeInjector 6105zqc, Yc6105zqc

Kufurira kwepre-jekiseni pane huru jekiseni kupisa maitiro yakadzidzwa mumabhuku.Mhedzisiro yacho inoratidza kuti chigadzirwa chekupisa chepre-jekiseni chine inhibitory mhedzisiro pakupisa kukuru kwejekiseni.Kana iyo yepamberi Angle yepre-jekiseni yakakura, iyo chaiyo chiyero che pre-jekiseni inogona kuvandudza iyo NOx kubuda.Kufuridzirwa kwemashure-injection kwakakurukurwa mumabhuku, uye zvakaonekwa kuti kuwedzera kwemashure-injection volume uye nguva inogona kuderedza kugadzirwa kweNOx, asi hupfumi hwemafuta hwakawedzera.Mhedzisiro yekumanikidzwa kwejekiseni uye nguva yejekiseni pakushandisa mafuta uye kuburitsa pasi peEGR mamiriro ekunze zvakadzidzwa mumabhuku.Mhedzisiro yacho inoratidza kuti yakakodzera jekiseni kudzvanywa uye jekiseni nguva inogona kukwirisa kushandiswa kwemafuta.Nekune rimwe divi, nekuti humburumbira dhayamita yeinjini yakaderera-speed two-stroke Marine inosvika mazana emamirimita, kuitira kuti mhepo ishandiswe zvizere mukamuri rinopisa, maviri kana anopfuura majekiseni emafuta anowanzo kurongwa kunze kwehumburumbira. , uye kurongeka kwemajekiseni emafuta kuchavawo nemigumisiro inokosha pakugadzirisa kupisa.Chidzidzo pamusoro pejekiseni Angle yejini-stroke dizeli injini yakaitwa mumabhuku, uye zvakaonekwa kuti kugadzirisa nzira yejekiseni kunogona kuderedza kugadzirwa kweNOx ne20%.Kufurira kweiyo nozzle kutungamira pakupisa uye kubuda kwakadzidzwa mumabhuku.Mhedzisiro yacho yakaratidza kuti iyo nozzle nzira yaive padyo zvakanyanya, uye nzvimbo dzakapfuma neoiri mucylinder dzakagadzirwa, izvo zvakawedzera kuburitsa soot.Yakanyanya divergent nozzle direction inowedzera musanganiswa wakaonda, kuderedza kushandiswa kwemafuta asi kuwedzera NOx emission.
