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

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 zaseLwandle ezisezantsi ukuhlangabezana nemigangatho yokukhutshwa kweTier III: (1) iteknoloji yokunciphisa i-catalytic (selectivecatalyticreduction, SCR) iteknoloji yokunciphisa i-NOx ngokongeza i-urea N2, idinga i-extra iseti yezixhobo ezinkulu zasemva kokulungiswa, kunye neendleko eziphezulu zokulondolozwa; (2) itekhnoloji ye-exhaust-gas recirculation (EGR) inciphisa 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 zaselwandle ukuphuculwa koyilo lwesistim yesitofu kunye nokuguquguquka kwesicwangciso sokutofa kubonakalise ukuba namandla amakhulu okuphucula i-oyile ekwi-cylinder kunye negesi yokuxuba kunye nenkqubo yokutsha. Kuncwadi i-algorithm ye-micro-genetic isetyenziselwa ukunyusa iiparameters zangaphambili ze-injection kwaye kufunyenwe ukuba isicwangciso esifanelekileyo sokujova ngaphambili singanciphisa ixesha lokulibaziseka komlilo siphucule ukusebenza kakuhle kokutsha kunye nokunciphisa ngokufanelekileyo ukusetyenziswa kwamafutha.
