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 yakaringana 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 yekumanikidza jekiseni uye nguva yejekiseni pakushandiswa kwemafuta 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 emamilimita, kuitira kuti mweya unyatsoshandisa mhepo 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%. Pesvedzero yeinotungamira yenozzle pakupisa uye kubuda yakadzidzwa mumabhuku. Mhedzisiro yacho yakaratidza kuti iyo nozzle nzira yaive padhuze 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.
