I-Diesel Injector Fuel Injector 5296723 Denso Injector ye-Foton Aulin 2.8 D, Cummins Engine Isf3.8

Umjovo kaphethiloli uyingxenye ebalulekile yokusebenza kudivayisi yomjovo kaphethiloli wenjini yedizili. Ikakhulukazi yakhiwe ngomjovo wamafutha kanye nomzimba wokujova uwoyela. Isikhundla sayo sokufaka kanye ne-Angle ekhanda le-cylinder kuncike ekuklanyweni kwegumbi elivuthayo. Umjovo kaphethiloli wenza i-atomize uphethiloli womfutho ophezulu othunyelwa yiphampu yomjovo kaphethiloli ube isifutho okulula ukubamba umlilo futhi sishise, futhi senza isifutho sihambisane nosayizi nokuma kwegumbi elivuthayo bese sihlakazeka siye egumbini elivuthayo bese sixuba umoya. Ngaphezu kokuthinta ikhwalithi ye-atomizing, ukusatshalaliswa kanye nokungena kwezici zesifutho sikaphethiloli, umjovo ubuye ube nomthelela omkhulu kumfutho womjovo, indawo yokuqala yomjovo, ubude besikhathi somjovo kanye nezinga lomjovo. Ngakho-ke, i-fuel injector idlala indima ebalulekile ekusebenzeni kwenjini ye-diesel.

Umgomo wokusebenza komjovo kaphethiloli

Ingxenye eyinhloko esebenzayo yomjovo umbhangqwana we-nozzle, owakhiwa i-valve yenaliti kanye nomzimba we-valve yenaliti. Ngokuvamile, i-valve yenaliti ivaliwe ngaphansi kwengcindezi elawula intwasahlobo ku-injector. I-plunger yepompo yomjovo kaphethiloli icindezela uphethiloli futhi idlulisela uphethiloli ocindezelwe ophezulu wokucindezela uwoyela egumbini lokugcina uwoyela lombhobho, okwenza i-PD yokucindezela ekamelweni lokugcina uwoyela ikhuphuke. Lapho umfutho kaphethiloli PD egumbini lokugcina uwoyela uphakeme kunokucindezela kokuvula i-PNO valvu yewashi ikhuphuka, uphethiloli ufuthwa ngaphandle kwegebe eliphakathi kwenozzle nevalvu yenaliti enkungu.
