Dizilo Injector Fuel Injector 0445120474 yogwirizana ndi injector Weichai Wp10

Ma injini a dizilo otsika othamanga awiri a Marine, omwe amadziwika ndi chuma chabwino komanso kudalirika kwambiri, amagwiritsidwa ntchito kwambiri m'zombo zazikulu, akuyendetsa pafupifupi 70% ya kuchuluka kwa katundu wapadziko lonse lapansi, ndikuchita gawo lofunikira pazachuma padziko lonse lapansi. Low liwiro awiri sitiroko Marine injini dizilo ali mkulu mphamvu ndi mkulu umuna wa zinthu zoipa. Bungwe la International Maritime Organization (IMO) linayamba kugwiritsa ntchito mfundo za Tier III m'madera ena oyendetsa mpweya mu 2016, zomwe zimafuna kuti injini za dizilo za Marine zothamanga kwambiri kuposa 130r / min kuti zitulutse zosaposa 3.4g/(kW·h) za NOx mkati mwa malo owongolera umuna. Zombo zomwe zimalephera kukwaniritsa miyezo yotulutsa mpweya zimakumana ndi vuto lolephera kupita kumtunda m'maiko ena otukuka. Pakalipano, pali njira ziwiri zamakono zama injini a dizilo a Marine otsika kwambiri kuti akwaniritse miyezo ya Tier III: (1) teknoloji yochepetsera (selectivecatalyticreduction, SCR), kuchepetsa kuchepetsa NOx powonjezera urea N2, kumafunika zida zowonjezera zochulukirapo pambuyo pokonza, komanso mtengo wokonza; (2) utsi-gasi recirculation (EGR) amachepetsa kuyaka kutentha mu yamphamvu poyambitsa utsi-gasi, potero inhibiting m'badwo wa NOx mu yamphamvu, koma chifukwa cha kuchuluka mafuta. M'zaka zaposachedwa, ndikugwiritsa ntchito koyambirira kwaukadaulo waukadaulo wapa njanji wothamanga kwambiri pama injini otsika a Marine, kuwongolera kachitidwe ka jakisoni ndi kusinthasintha kwa njira ya jakisoni kwakhala ndi kuthekera kwakukulu kopititsa patsogolo kusanganikirana kwamafuta ndi gasi mu silinda ndi kuyaka. M'mabuku, ma aligorivimu ang'onoang'ono amagwiritsidwa ntchito kukhathamiritsa magawo a jakisoni, ndipo amapezeka kuti njira yoyenera yojambulira isanakwane imatha kufupikitsa nthawi yochedwa, kuwongolera kuyatsa bwino komanso kuchepetsa kugwiritsa ntchito mafuta.
