I-Auto Parts Fuel Injector Diesel Injection 178-0199 ye-CAT Auto Fuel Common Rail Injector

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) ukunciphisa okunamandla kwe-NOx ngokungeza i-urea N2, idinga enye eyengeziwe. isethi yemishini emikhulu yangemuva 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 esinengcindezi ephezulu ezinjinini zasolwandle ezinejubane eliphansi ukuthuthukiswa kwesakhiwo sohlelo lomjovo kanye nokuguquguquka kwesu lomjovo kuye kwabonakala kunamandla amakhulu okuthuthukisa ukuxutshwa kukawoyela oyi-cylinder negesi kanye nenqubo yokuvutha. Ezincwadini i-algorithm yezakhi zofuzo ezincane isetshenziselwa ukuthuthukisa imingcele yangaphambi komjovo futhi kutholakala ukuthi isu elifanele lokujova langaphambi komjovo lingafinyeza isikhathi sokubambezeleka kokuthungela lithuthukise ukusebenza kahle komlilo futhi linciphise ngempumelelo ukusetshenziswa kukaphethiloli.
