I-Diesel Injector Fuel Injector 0445120151 Bosch ye-Ko-Matsu PC200-8 PC210-8 SAA6d107e-1 Engine Cummins Industrial Engines

Umthelela we-Double Injector on Combustion Process ku-396 Series Diesel Engine (ingxenye6)

Umfanekiso 6, Umfanekiso 7 kanye noMfanekiso 8 ubonisa ukuthi, lapho ubude bomjovo bufinyezwa, ukuvutha

isikhathi sokulibaziseka sifinyezwa kancane futhi indawo yokuqala yomlilo isithuthukisiwe. Uma izinga eliphezulu lokukhishwa kokushisa komlilo liphezulu, yilapho isigaba esihambisanayo siba ngaphambili. Lapho ukucindezela okukhulu komlilo kukhuphuka, isigaba esihambisanayo sithuthukisiwe. Uma izinga lokushisa eliphakeme elimaphakathi kusilinda linyuswa, isigaba esihambisanayo siyathuthukiswa kodwa izinga lokushisa elimaphakathi kusilinda phakathi nesikhathi sokuvutha sakamuva liyehliswa kancane. Ukukhishwa kokushisa okuvuthayo kugxilile, ukukhululwa kokushisa okuqoqiwe kuyafana, kodwa ukukhishwa kwe-NO kukhuphuke kakhulu.13

Njengoba iphoyinti lokuqala lomjovo ligcinwa liku-352°CA, ubude besikhathi somjovo obufushane, uphethiloli

okufuthwe kusilinda kuyandiswa nge-engeli efanayo ye-crank kanye nebanga elingenayo liyakhuphuka.14 Lokhu kuhambisa ekuxubeni kukaphethiloli okwengeziwe nomoya kanye ne-atomization kaphethiloli engcono, ngakho isikhathi sokulibaziseka kokuvutha siyafinyezwa, ukusha kukaphethiloli okuxutshwe ngaphambili kuyenziwa. ukwanda, futhi ukuvutha kokusabalalisa kuyashesha. Ngenxa yalokho, ukukhululwa kokushisa okuvuthayo kugxilile, ukucindezela komlilo kanye nezinga lokushisa le-cylinder liyakhuphuka, futhi AKUKHO ukukhiqizwa kwanda ngokufanele15. Umfanekiso 9 ubonisa ingxenye yedizili esabalalisa ethathwe esigabeni esiphambanayo endaweni ephakeme efana nembobo yombhobho ku-380°CA. Kungatholakala ukuthi njengoba ubude bomjovo bufinyezwa, ukusha kuqala kuqala futhi kugxile kakhulu; ngaphezu kwalokho, ingxenye yedizili esele yehliswa ku-380°CA kanti ingxenye yangemuva kokushiswa nayo iyancipha. Lokhu kuyasiza ekuthuthukiseni amandla asebenzayo.
