Ikhwalithi Ephakeme I-Common Rail Diesel /Fuel Injector Nozzle DLLA140P643

Amasu amabili amakhulu ezobuchwepheshe ekuthuthukisweni kobuchwepheshe benjini ye-diesel ahlobene nohlelo lukaphethiloli. Ukusetshenziswa kobuchwepheshe bokulawula i-elekthronikhi kuthathwa njengengqophamlando ekuthuthukisweni kobuchwepheshe benjini kadizili.

Izingxenye eziyinhloko ze-fuel injector yi-solenoid valve, i-valve yokulawula, i-piston kanye nezingxenye ze-valve inaliti. Uphethiloli womfutho ophezulu uthuthwa ngepayipi lesitimela elivamile. Kunemizila emibili yokulethwa kukaphethiloli kumjovo kaphethiloli, enye ingena egumbini lokulawula ngaphezu kwepiston yokulawula bese enye ingena egunjini le-accumulator phezulu kwevalve yenaliti. Lapho i-valve ye-solenoid ingenawo amandla, i-outlet yamafutha ekamelweni lokulawula ivaliwe. Ngenxa yokuthi indawo ye-cross-sectional ye-piston yokulawula inkulu kunendawo ye-valve yenaliti ye-conical pressure surface, ihlanganiswe namandla okulayisha ngaphambili e-piston spring, i-valve yenaliti icindezelwe ngokuqinile endaweni yokuhlala; Lapho i-valve ye-solenoid ithola isignali yokulawula futhi ixhunyiwe, imbobo yokukhipha uwoyela ivulwa kancane kancane, ngalesi sikhathi, umehluko wokugeleza kukaphethiloli egumbini lokulawula uyancipha kancane kancane, ingcindezi yoketshezi ku-piston iyancipha, i-valve yenaliti kancane kancane. ikhuphuka, uphethiloli ugeleza ekamelweni lokucindezela le-nozzle ngemva komgodi wokufafaza, ukwakheka kwe-fuel spray. Lapho amandla e-valve ye-solenoid, amandla kazibuthe kagesi encishisiwe, ingcindezi ye-hydraulic akwanele ukunqoba amandla okulayisha kuqala entwasahlobo nokwenza i-valve yenaliti ihlale futhi, ukuphela komjovo kawoyela.
