Dizilo Injector Fuel Injector 0445120103 Bosch ya Dodge RAM 2500 / RAM 3500 5.9L Cummins Turbo Dizilo I6 injini

Kutengera Injector Yothamanga Kwambiri ya Dizilo ICE(gawo 2)

Zomwe zimaganiziridwa kuti ndizofunikira za lamulo la jakisoni wamafuta m'makina zimagwiritsa ntchito kuthamanga kosinthika, kuphatikiza mu Common Rail systems [1,2].Ma jekeseni a Electrohydraulic (EHI) m'makinawa amapangidwa kuti agwiritse ntchito jakisoni wa ma multicycle ndi kuchuluka kwa ma cycle ndi kuchuluka kwa ntchito kumachepetsedwa ndi liwiro la jekeseni.Kuchepetsa pang'ono kwa liwiro la ntchito ndi chifukwa cha kusinthasintha kwa jekeseni malinga ndi zovuta zake zogwirira ntchito.Zotsatira za kuthamanga kosakwanira kogwira ntchito ndikupatuka kwa momwe jakisoni weniweni amafunikira [3-5].

2 Kuthamanga kosalekeza kwa jekeseni wothamanga kwambiri

Ma jekeseni a electrohydraulic akuphatikizapo

- chowongolera ngati singano yokhala ndi chowonjezera choyimira silinda ya hydraulic yokhala ndi m'mimba mwake yachipinda chogwirira ntchito yopitilira singano m'mimba mwake ndikupanga chipinda chowongolera, ndi kasupe wa singano woyimira chida chosindikizira pakalibe kukakamizidwa;

- chipangizo chowongolera kupanikizika mu chipinda chowongolera cha ochulukitsa ngati mawonekedwe a slider kapena valavu yokhala ndi solenoid drive.

Valavu 4 ndi yaying'ono, choncho ndi valavu yothamanga kwambiri popeza kutuluka kwakukulu kwa mafuta ojambulidwa sikudutsa.Kumbali ina, kuyenda kwa singano 7 kumayendetsedwa ndi mphamvu ya hydraulic ya valve.Valve ili pambali yotulutsa, yomwe imathandizira kamangidwe kake, imateteza kuthekera kwa kuzizira, imachepetsa zofunikira za hydraulic tightness yake ndikuchepetsa mphamvu yofunikira kuti iwononge.Mapeto a solenoid 1 ndi disk armature 3 amatsegula valavu ya mpira 4 pogonjetsa kasupe 2. Kuthamanga kochokera pamwamba pa kuchulukitsa kumachepa, ndipo singano imatsegula njira yopita ku injector orifices 8. Pambuyo pa solenoid 1 ndi deenergized ndipo kukonzanso ma valve, kukakamiza kumanja kwa chochulukitsa kumabwezeretsedwa kudzera mu jet ya atomizing (Chithunzi 1)
