I-Diesel Injector Fuel Injector 0445120277 Bosch ye-FAW J6 Ca6dm2 Xichai Engine

I-injector plunger ibambekile
Ngemva kokuhlaziya, kwatholakala ukuthi i-plunger (kanye nesilinda) yesijovo sikaphethiloli esinephutha konke kwakunokuqina phezulu. Ngokuhlaziywa kwedatha, kutholakala ukuthi inani elikhulu lama-injection lisenokwehluleka kwe-jamming phakathi nesikhathi sokusebenza sika-0-500h (kude kakhulu ngaphansi kokuphila kokuklama komjovo). Ukuze uchaze kangcono lesi simo, i-injector enephutha phakathi kuka-0-500h iyahlakazwa. Kwatholakala ukuthi i-plunger yomjovo yayinzima kakhulu, futhi kwakungekho carbon deposit nokunye ukungcola emseleni we-plunger. Ngokwalesi simo, kunqunywa ngokuyisisekelo ukuthi isizathu esibaluleke kakhulu esithinta impilo yesevisi yomjovo ukuthi igebe phakathi kwe-plunger nomkhono we-plunger lincane kakhulu, okuholela ekugxumeni kwe-plunger.
4.2 Ukuvuza kwe-injector reverse (ukubala okungu-25.6%) Isenzakalo sokuthi uphethiloli uvuza esipholiseni sekhanda likawoyela kuthiwa yi-reverse leakage. Ngokudilizwa, kuphinde kwatholakala ukuthi into ebambekile yevalve yenaliti ibikhona kuzijovo zikaphethiloli ezinokuvuza okubuyela emuva. Ngesikhathi esifanayo izibalo zithola: ngemuva kokuthi izinga lokushisa likawoyela kaphethiloli lidlule ku-97 ℃, ukuvuza okungemuva kwesijojo sikaphethiloli kuzokhuphuka.
Okuhle nokuvuzayo (kubala u-3.28%)
Isenzo sokuthi uwoyela opholisa ikhanda likawoyela uvuzela kuphethiloli bese uyasha ubizwa ngokuthi ukuvuza okuhle.
Kwatholakala esizeni ukuthi izinga lokwehluleka komjovo kaphethiloli liguquguquka kakhulu ngomkhiqizo kawoyela. Ngemuva kokuhlolwa, kwatholakala ukuthi lapho izinga lokushisa likaphethiloli lenyuka laya ku-102C (ngalesi sikhathi, i-kinematic viscosity kaphethiloli yehla yaba ngu-6Sct), i-plunger empeleni ayizange ibambeke: kodwa ngenxa yokuthi izinga lokushisa laliphezulu kakhulu ngemva komjovo. ngenani lokwehluleka kokuvuza okuhle kanye nokuvuza okuhlanekezelwe komjovo kaphethiloli kuqinisekisa isiphetho sangaphambilini: isizathu esiyinhloko esithinta impilo yesevisi yomjovo kaphethiloli ukuthi igebe phakathi kwe-plunger. futhi umkhono we-plunger mncane kakhulu, okwenza ukuthi i-plunger ibhajwe.
Ngokuhlaziywa okuphelele okungenhla, kunqunywa ukuthi imbangela yenkinga yile: ngenxa yokushintshwa kwekhwalithi yamafutha, igebe phakathi kwe-plunger yokujova kanye ne-valve yenaliti lincane kakhulu, okwenza lingakwazi ukuzivumelanisa nezimo ezintsha zokusebenza. futhi kwandisa izinga lokuhluleka.
