I-Diesel Injector Fuel Injector 0445120474 iyahambisana nomjovo Weichai Wp10

Izinjini zikadizili zasolwandle ezinejubane eliphansi, ezibonakala ngomnotho omuhle nokuthembeka okuphezulu, zisetshenziswa kakhulu emikhunjini emikhulu, zishayela cishe u-70% wevolumu yempahla yomhlaba wonke, futhi zidlala indima ebalulekile ohlelweni lwezomnotho lomhlaba. Ijubane eliphansi eliphindwe kabili Injini kadizili yasolwandle inamandla aphezulu kanye nokukhipha izinto eziyingozi. I-International Maritime Organisation (IMO) yaqala ukusebenzisa izindinganiso ze-Tier III kwezinye izindawo zokulawula ukungcola ngo-2016, idinga izinjini zikadizili zaseMarine ezinesivinini esingaphansi kuka-130r/min ukuthi zikhiphe okungaphezu kuka-3.4g/(kW·h) we-NOx ngaphakathi indawo yokulawula ukungcola. Imikhumbi ehlulekayo ukuhlangabezana nezindinganiso zokukhishwa kwekhabhoni ibhekene nokungakwazi ukuya ogwini kwamanye amazwe athuthukile. Njengamanje, kunemizila emibili eyinhloko yobuchwepheshe yezinjini zedizili ze-Marine ezinesivinini esiphansi ukuze zihlangabezane nezindinganiso zokukhishwa kwe-Tier III: (1) ubuchwepheshe bokunciphisa okukhethiwe (selectivecatalyticreduction, SCR), ukuncipha okunamandla kwe-NOx ngokungeza i-urea N2, idinga isethi eyengeziwe yezinto ezinkulu zangemuva kokucubungula, kanye nezindleko zokuyilungisa eziphezulu; (2) ubuchwepheshe be-exhaust-gas recirculation (EGR) bunciphisa izinga lokushisa elivuthayo kusilinda ngokwethula i-exhaust-gas, ngaleyo ndlela kuvimbela ukukhiqizwa kwe-NOx kusilinda, kodwa okuholela ekwandeni kokusetshenziswa kukaphethiloli. Eminyakeni yamuva nje, ngokusetshenziswa kokuqala kobuchwepheshe besitimela obuvamile obunengcindezi ephezulu ezinjinini zasolwandle ezinejubane eliphansi, ukuthuthukiswa kwesakhiwo sohlelo lomjovo kanye nokuguquguquka kwesu lomjovo kuye kwabonakala kunamandla amakhulu okuthuthukisa inqubo yokuxutshwa kukawoyela oyi-cylinder negesi kanye nokuvutha. Ezincwadini, i-algorithm yezakhi zofuzo ezincane isetshenziselwa ukuthuthukisa imingcele yangaphambi komjovo, futhi kutholakala ukuthi isu elifanele lokujova langaphambi kokujova linganciphisa isikhathi sokulibaziseka ukuthungela, lithuthukise ukusebenza kahle komlilo futhi linciphise ngempumelelo ukusetshenziswa kukaphethiloli.
