I-Diesel Injector Fuel Injector 0445120071 Bosch ye-Cummins Qsb6.7 Isb6.7 Engine

Ukuhlolwa kwama-injection kaphethiloli
Uma izimo zivuma, umjovo kaphethiloli ungafakwa ngokuqondile ebhentshini lokuhlola lomjovo kaphethiloli ukuze uhlolwe ngokwezidingo ezishiwo. Uma kungekho ibhentshi lokuhlola i-fuel injector, ukulungiswa kungabhekwa ngokuqondile enjini ye-diesel, engenziwa ngezindlela ezimbili ezilandelayo:
(1) Okokuqala lungisa umjovo ojwayelekile wamafutha (umjovo kaphethiloli omfutho womjovo kaphethiloli kanye nekhwalithi yesifutho iyahlolwa futhi ilungiswe) kanye nejoyinti lezindlela ezintathu, lifake empompini yokujova uphethiloli (ipompo yomjovo kaphethiloli kufanele inikeze uwoyela ngokujwayelekile) Vuliwe. i-valve yokuphuma kwamafutha, yenza ukuhlola okuqhathanisayo. Beka i-throttle endaweni ephezulu yokunikeza uwoyela, cindezela injini ye-diesel, uzungezisa i-crankshaft ngesivinini esingu-100 ~ 200 r/min, futhi uqhathanise isijojo sikaphethiloli esijwayelekile nesijovo sikaphethiloli esihloliwe.
Uma umjovo kaphethiloli ojwayelekile kanye nomjovo kaphethiloli ohloliwe ujova uphethiloli ngesikhathi esifanayo, i-atomization ilungile, umsindo womjovo kaphethiloli ucwebile, futhi akukho ukuvuza kwamafutha nokuconsa, kusho ukuthi ingcindezi yomjovo kaphethiloli kanye nekhwalithi ye-atomization i-fuel injector ehloliwe ifanelekile. Uma umjovo ohloliwe ujova uwoyela ngaphambi noma ngemuva komjovo ojwayelekile, kusho ukuthi umfutho womjovo womjovo ohloliwe uphansi noma uphakeme, futhi kufanele ulungiswe ngokufaka isikulufu esilawula ukucindezela phakathi noma ukubuyisela emuva isikulufu esilawula ukucindezela, kuze kube yilapho isijojo sikaphethiloli esihloliwe siwumphumela. efanayo naleyo ejwayelekile. Uma ama-injection amabili kaphethiloli ejova uphethiloli ngesikhathi esisodwa, futhi umjovo kaphethiloli otholiwe une-atomization embi, imishayo kawoyela noma amaconsi kawoyela, kusho ukuthi kunenkinga ngokuhlangana kwe-valve yenaliti enaliti, futhi idinga ukulungiswa noma ukushintshwa.
