Umjovo omusha we-Dlla147s071 we-Injector 6105zqc, Yc6105zqc

Umthelela womjovo wangaphambili enqubweni yokushiswa komjovo oyinhloko uhlolisiswe ezincwadini. Imiphumela ibonisa ukuthi umkhiqizo ovuthayo womjovo wangaphambili unomphumela ovimbelayo ekushiseni komjovo oyinhloko. Uma i-engeli engaphambi komjovo inkulu, inani elifanele lomjovo wangaphambili lingathuthukisa ukukhishwa kwe-NOx. Umthelela we-post-injection waxoxwa ngawo ezincwadini, futhi kwatholakala ukuthi ukwandisa umthamo we-post-injection kanye nekhefu kunganciphisa ukukhiqizwa kwe-NOx, kodwa umnotho wephethiloli wawubi kakhulu. Imithelela yengcindezi yomjovo nesikhathi sokujova ekusetshenzisweni kukaphethiloli kanye nokuphumayo ngaphansi kwe-EGR atmosphere kuhlolisiswe ezincwadini. Imiphumela ibonisa ukuthi ingcindezi yomjovo efanelekile kanye nesikhathi somjovo singathuthukisa ukusetshenziswa kukaphethiloli. Ngakolunye uhlangothi, ngenxa yokuthi ububanzi besilinda senjini ye-Marine enesivinini esiphansi esiphindwe kabili bufika emamilimitha angamakhulu, ukuze kusetshenziswe umoya ngokugcwele endaweni evuthayo, ama-injection kaphethiloli amabili noma ngaphezulu ngokuvamile ahlelwa ngaphandle kwesilinda. , kanye nokuhlelwa kwama-injector kaphethiloli nakho kuzoba nomthelela omkhulu enqubweni yokuvutha. Ucwaningo lwe-Angle yomjovo wenjini ye-diesel ene-stroke emibili lwenziwe ezincwadini, futhi kutholakala ukuthi ukulungisa isiqondiso somjovo kunganciphisa ukukhiqizwa kwe-NOx ngo-20%. Umthelela wesiqondiso se-nozzle ekushiseni nasekukhishweni kwafundwa ezincwadini. Imiphumela yabonisa ukuthi isiqondiso se-nozzle sasiseduze kakhulu, futhi izindawo zendawo ezinothile ngowoyela kusilinda zakhiwe, okwandisa ukukhishwa kwe-soot. Isiqondiso se-nozzle esihluke kakhulu sizokwandisa ingxube encane, kunciphise ukusetshenziswa kukaphethiloli kodwa kukhuphule ukuphuma kwe-NOx.
