I-Diesel Injector Fuel Injector 0445120145 Ihambisana Ne-Bosch Cr/IPL26/Ziris20s

Umthelela we-Double Injector on Combustion Process ku-396 Series Diesel Engine (ingxenye 2)

1 1Isingeniso

Injini yedizili engu-396 isetshenziswe kabanzi emikhunjini yasekhaya, ezimotweni nasezimbonini zamandla kagesi, njll., ngoba injini inokusebenza okuthembekile, impilo ende yesevisi, amandla aphezulu kanye nomnotho futhi ingaguqulwa isetshenziswe kwezinye izinto ezibaswayo ezifana negesi yemvelo. .1-3.Ngokuncishiswa okwandayo kwemithombo ye-petroleum, ukusetshenziswa kwamafutha e-biodiesel kanye notshwala (njenge-methanol ne-ethanol) enjinini yedizili kuyenyuka.

Njengoba uphethiloli wotshwala ungahlangani nodizili, inani likaphethiloli wotshwala kuphethiloli oxubile kaphethiloli wotshwala nodizili ngokuvamile lingaphansi kuka-10%.Uphethiloli oxubile unokuzinza okuphansi, ubekwe kalula futhi awukwazi ukugcinwa isikhathi eside ngisho nokwengezwa kwe-cosoluent.4-6 Kunconywa ukusebenzisa uphethiloli wotshwala enjini ye-diesel nge-double-injection.Enye indlela iwukufafaza uphethiloli wotshwala endaweni eningi oyithathayo bese ufafaza udizili njengophethiloli wokuthungela kusilinda, futhi enye indlela iwukufafaza ngokuqondile uphethiloli wotshwala nodizili kusilinda ngama-injection ahlukene, ngodizili obasa uphethiloli wotshwala.

Isistimu yomjovo kaphethiloli yenjini yokuqala engu-396 yochungechunge lwe-diesel yashintshwa, futhi ama-injection amabili afanayo angama-4 afakwe kusilinda ngasinye.Ngakho-ke, udizili ungafuthwa ngama-injector amabili, noma umjovo owodwa ungasetshenziswa ukufafaza udizili kanti omunye umjovo ungasetshenziswa ukufafaza i-biodiesel noma uphethiloli wotshwala.

Imodeli yokuvutha engu-3D yochungechunge lwe-396 injini yedizili isungulwa kusetshenziswa isoftware ye-computational fluid dynamics FIRE, kanye nenqubo yokuvutha lapho kwamukelwa ama-injector angama-5-hole kanye nezimbobo eziyi-8 kanye nomjovo we-doal-hole ongu-4 waqhathaniswa futhi wahlaziywa ngokulingisa. indlela ukuze kuthuthukiswe inqubo yokushiswa kwenjini engu-396 yochungechunge lwe-diesel ene-dual-injector kanye nokuhlinzeka ngesisekelo sokusebenzisa i-biodiesel kanye nophethiloli wotshwala esikhathini esizayo.7, 8.
