Auto Parts Fuel Injector Diesel Injection 178-0199 yeCAT Auto Fuel Common Rail Nozzle Injector

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 dzekudzika-speed Marine diesel engines kusangana neTier III emission standards: (1) iyo yakasarudzika inokonzeresa kuderedza (selectivecatalyticreduction, SCR) tekinoroji iyo catalytic kuderedzwa kweNOx nekuwedzera urea N2, inoda imwezve. seti yemidziyo yakakura yemashure-yekugadzirisa, uye mutengo wakakura wekugadzirisa; (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 dhizaini uye jekiseni zano kuchinjika kwakaratidza kuve nekugona kukuru kwekuvandudza mu-cylinder oiri uye gasi musanganiswa uye kupisa maitiro. Muzvinyorwa iyo micro-genetic algorithm inoshandiswa kukwirisa pre-injection paramita uye inowanikwa kuti yakakodzera pre-jekiseni zano rinogona kupfupisa kunonoka kunonoka nguva inovandudza kupisa kwemoto uye zvinobudirira kuderedza kushandiswa kwemafuta.
