I-Diesel Injector Fuel Injector 0445120142 Bosch for Yamz 65011112010 Cr/IPL32/Ziris20s

Umthelela we-Double Injector on Combustion Process ku-396 Series Diesel Engine (ingxenye 1)

Abstract.

Injini ye-diesel engu-396 inokusebenza okuphezulu, ukwethembeka nempilo ende yesevisi, esetshenziswe kabanzi emikhakheni eminingi ehlanganisa umkhumbi, imoto kanye neyunithi yamandla ezimboni. Ngohlelo lomjovo oluthuthukisiwe kanye nomjovo okabili kusilinda ngasinye, izijovo ezimbili zikadizili zingafutha udizili ngesikhathi esisodwa; noma umjovo oyedwa ufafaza udizili wokuthungela kanti omunye umjovo ufutha i-biodiesel noma uphethiloli wotshwala.

Imodeli evuthayo eyi-3D yochungechunge lwenjini yedizili engu-396 enegumbi elivuthayo le-convex eliphansi phezulu isungulwa kusetshenziswa i-computational fluid dynamics.

isoftware FIRE, kanye nenqubo yomlilo lapho kwamukelwa umfaniswano wezimbobo ezi-5 nezingu-8 kanye nomjovo okabili wemigodi emi-4 kuyenziwa ukuqhathanisa nokuhlaziya isifutho sikaphethiloli, indawo yokuqala yokuthungela, ingcindezi yomlilo, izinga lokukhishwa kokushisa komlilo, izinga lokushisa elimaphakathi. kusilinda futhi AKUKHO ukuphuma. Uma iqhathaniswa nenjini kadizili ethatha i-8-hole injector, injini kadizili esebenzisa i-4-hole dual-injector inendawo ebanzi yokusatshalaliswa kwesikhala, ingcindezi ephezulu kanye nezinga lokushisa kusilinda, kanye nokusebenza kahle okushisayo okushisayo.

Inqubo yokushiswa komjovo ubude besikhathi esingu-26.84°CA, 22°CA kanye ne-20°I-CA ye-396 series engine diesel ethatha i-4-hole dual-injector ilingisiwe

ngokulandelana, futhi umphumela wokulingisa ubonisa ukuthi ubude besikhathi somjovo obufushane bungakwazi ukuletha ukucindezela okuphezulu okuphezulu kanye nesilinganiso esiphezulu sokushisa esimaphakathi kusilinda, isikhathi esifushane sokulibaziseka ukuthungela, indawo yokuqala yokuthungela ethuthukisiwe, inani eliphakeme eliphakeme lezinga lokukhishwa kokushisa komlilo, kakhulu ukukhululwa kokushisa komlilo okugxilile, ukukhishwa kwe-NO okuphezulu.

Lezi zimo ezintathu zicishe zibe nokukhululwa okufanayo kokushisa okuqoqiwe kanye nokusetshenziswa kukaphethiloli okuphelele uma kuqhathaniswa. Ubude besikhathi somjovo obufanele buyokhethwa ngokusekelwe ekucatshangelweni okuphelele kwengcindezi kusilinda, amandla asebenzayo kanye AKUKHO ukuphuma. Lo mphumela wocwaningo uyasebenza ukuthuthukisa inqubo yokushiswa kwenjini ye-396 series ene-dual-injector futhi inikeza isisekelo sokusebenzisa i-biodiesel kanye nophethiloli wotshwala enjinini kadizili.
