I-Diesel Injector Fuel Injector 0445120149 Bosch ye-Longgong855 Forklift Engine Weichai Wd10

Umthelela we-Double Injector on Combustion Process ku-396 Series Diesel Engine (ingxenye 5)

Lapho i-injector ye-8-hole yamukelwa, umthelela webanga elincishisiwe lokungena enqubweni yokuvutha uyaqiniswa, indawo ephelele yokusabalalisa uphethiloli kanye nokushiswa okuxutshwe ngaphambili kuyancishiswa, futhi ukushiswa kokusabalalisa kuyancishiswa, ngaleyo ndlela kwenza ukushisa kungaqedi futhi. ukusebenza kahle okushisayo kuphansi. Ngemuva kokuthi i-4-hole i-double-injector yamukelwe, njengoba ama-injection amabili ehlukaniswa ibanga elithile, indawo yokusabalalisa indawo kaphethiloli iyanda, futhi umphumela wokuxuba phakathi kwe-fuel spray nomoya ku-cylinder uqiniswa.

Nakuba ibanga lokungena liselifushane futhi ukushiswa okuxutshwe ngaphambilini kusengaphansi kwalokho komjovo wezimbobo ezi-5, ukukhululwa kokushisa okuqoqiwe kulingana nalelo lomjovo onezimbobo ezi-5 ngoba umoya okusilinda usetshenziswa ngokugcwele, ukusha. ubude besikhathi sokusha kokusabalalisa buthe ukuba kude futhi ukuvutha kuphelele kakhulu. Umfanekiso wesi-5 ubonisa ukuthi, lapho i-injector ye-8-hole yamukelwa, ukushiswa akuphelele, ingcindezi yokusha kanye nezinga lokushisa elijwayelekile ku-cylinder kanye nokukhishwa kwe-NO kuphansi. Uma kwamukelwa i-4-hole-double-injector, ukukhishwa kwe-NO cishe ku-60% kwalokho komjovo wemigodi emi-5 ngenxa yezinga lokushisa eliphansi eliphezulu lokuvutha.

4 Imiphumela yokulingisa nokuhlaziywa kokufinyeza ubude besikhathi somjovo we-4-hole dual-injector

Ngaphansi kwesimo sokuthi ubude bomjovo kanye nendawo yokugeleza esebenzayo akuguquki, ukusebenza kahle kokushisa kuyancishiswa lapho kushintsha i-injector ye-5-hole kumjovo we-8-hole. Kodwa-ke, uma i-4-hole dual-injector yamukelwa, ukusebenza kahle kwe-thermal kugcinwa kufana nalokho komjovo we-5-hole. Uma ingcindezi yomjovo inyuswa, ubude bomjovo buyafinyezwa futhi ibanga lokungena le-oyela likhuphuka, ukuxutshwa kukaphethiloli nomoya kuyanda futhi inqubo yokuvutha iyathuthukiswa. Umfanekiso 6, Umfanekiso 7 kanye noFigure 8 ngokulandelana ubonisa ingcindezi kusilinda, izinga lokukhishwa kokushisa, izinga lokushisa elimaphakathi kusilinda, ukukhululwa kokushisa okunqwabelene kanye AKUKHO ingxenye enkulu yomjovo lapho i-engeli yomjovo ye-4-hole dual-injector ingu-26.84°CA, 22° I-CA kanye no-20°CA.
