Diesel Injector Fuel Injector 0445120474 inoenderana neinjector Weichai Wp10

Low speed two-stroke Marine diesel engines, inoratidzwa nehupfumi hwakanaka uye kuvimbika kwepamusoro, inoshandiswa zvakanyanya mungarava huru, ichityaira inenge 70% yehuwandu hwekutakura kwepasi rose, uye kutamba basa rinokosha muhurongwa hwehupfumi hwenyika. Low kumhanya maviri sitiroko Marine dhiziri injini ine simba rakawanda uye kuburitsa kwakanyanya kwezvinhu zvinokuvadza. Sangano reInternational Maritime Organisation (IMO) rakatanga kushandisa zviyero zveTier III mune dzimwe nzvimbo dzekudzora kuburitswa kwemhepo muna 2016, zvichida kuti injini dzedhiziri dzeMarine dzine spidhi yakaderera kupfuura 130r/min kuti ibudise isingapfuure 3.4g/(kW·h) yeNOx mukati me Emission control nzvimbo. Ngarava dzinotadza kuzadzisa mwero wekuburitsa hutsi dzakatarisana nekutadza kuenda kumahombekombe kune dzimwe nyika dzakabudirira. Parizvino, kune nzira mbiri huru dzehunyanzvi hwepasi-speed Marine dhiziri injini kusangana neTier III emission miyero: (1) iyo yakasarudzika catalytic reduction (selectivecatalyticreduction, SCR) tekinoroji, iyo catalytic kuderedza NOx nekuwedzera urea N2, inoda yakawedzera seti yeakawanda post-processing midziyo, uye yakakwirira yekugadzirisa mutengo; (2) exhaust-gas recirculation (EGR) tekinoroji inoderedza kupisa kwekupisa mucylinder nekuunza exhaust-gasi, nekudaro ichidzivirira chizvarwa cheNOx muhumburumbira, asi zvichikonzera kuwedzera kwemafuta. Mumakore achangopfuura, nekushandiswa kwekutanga kwekumanikidza kwakajairika njanji tekinoroji mune yakaderera kumhanya Marine injini, kuvandudzwa kwejekiseni system yekumisikidza uye jekiseni zano kuchinjika kwakaratidza kuve nekugona kukuru kwekuvandudza mu-cylinder oiri uye gasi musanganiswa uye kupisa maitiro. Muzvinyorwa, iyo micro-genetic algorithm inoshandiswa kukwidziridza pre-injection paramita, uye inowanikwa kuti yakakodzera pre-jekiseni zano rinogona kupfupisa kupisa kunonoka nguva, kunatsiridza kupisa kwemoto uye zvinobudirira kuderedza kushandiswa kwemafuta.
