Isitofu se-Diesel Fuel Injector 0445120474 iyahambelana ne-injector ye-Weichai Wp10

Iinjini zedizili zaseLwandle ezinesantya esiphantsi, ezibonakaliswa luqoqosho oluhle kunye nokuthembeka okuphezulu, zisetyenziswa kakhulu kwiinqanawa ezinkulu, ziqhuba malunga ne-70% yomthamo wempahla yehlabathi, kwaye zidlala indima ebalulekileyo kwinkqubo yezoqoqosho yehlabathi. Isantya esisezantsi istrowuku ezimbini Marine Injini yedizili inamandla aphezulu kunye nokukhutshwa okuphezulu kwezinto eziyingozi. I-International Maritime Organisation (IMO) yaqala ukuphumeza imigangatho ye-Tier III kwezinye iindawo zokulawula ukukhutshwa ngo-2016, ifuna iinjini ze-diesel zaseLwandle ezinesantya esingaphantsi kwe-130r / min ukuba zikhuphe akukho ngaphezu kwe-3.4g / (kW · h) ye-NOx ngaphakathi indawo yokulawula ukukhutshwa. Iinqanawa ezisilelayo ukuhlangabezana nemigangatho yokukhutshwa kwezinto ezikhutshwayo zijongene nokungakwazi ukuhamba ngolwandle kumazwe athile aphuhlileyo. Okwangoku, kukho iindlela ezimbini eziphambili zobugcisa kwiinjini zedizili ze-Marine ezinesantya esiphantsi ukuhlangabezana nemigangatho yokukhutshwa kweTier III: (1) iteknoloji yokunciphisa i-catalytic (selectivecatalyticreduction, SCR), ukunciphisa i-NOx ngokudibanisa i-urea N2, idinga iseti eyongezelelweyo yezixhobo ezinkulu zasemva kokulungiswa, kunye neendleko eziphezulu zokulondolozwa; (2) i-teknoloji ye-exhaust-gas recirculation (EGR) iyanciphisa ukushisa okutshisayo kwi-cylinder ngokuzisa i-exhaust-gas, ngaloo ndlela inqanda ukuveliswa kwe-NOx kwi-cylinder, kodwa kubangele ukwanda kokusetyenziswa kwamafutha. Kwiminyaka yakutshanje, ngokusetyenziswa kokuqala koxinzelelo oluphezulu lwetekhnoloji kaloliwe eqhelekileyo kwisantya esisezantsi iinjini zaseMarine, ukuphuculwa koyilo lwesistim yesitofu kunye nokuguquguquka kwesicwangciso sokutofa kubonakalise ukuba namandla amakhulu okuphucula i-oyile ye-cylinder kunye negesi yokuxuba kunye nenkqubo yokutsha. Kuncwadi, i-algorithm ye-micro-genetic isetyenziselwa ukunyusa iiparameters zangaphambili, kwaye kufunyenwe ukuba isicwangciso esifanelekileyo sokujova ngaphambili singanciphisa ixesha lokulibaziseka komlilo, ukuphucula ukusebenza kokutsha kunye nokunciphisa ngokufanelekileyo ukusetyenziswa kwamafutha.
