Binciken jihohi na wucin gadi na injin injectors na CI tare da amfani da hanyoyin gani(KASHI NA 7)

Ga masu allura biyu ana ɗaukar jinkirin amsawar hardware a matsayin akai-akai kuma 0.012 ms ne na piezo- da 0.016 don injector na solenoid. Kamar yadda siginar hasken diode ke faruwa akan firam guda bayan farkon kowane ma'auni, ana iya bayyana cewa ma'auni sun tabbata kuma ana iya maimaita su. Hoto na 5 yana gabatar da ɗan gajeren lokacin ƙarfafawa ga nau'ikan alluran guda biyu, kamar yadda aka riga aka ambata a cikin hanyoyin bincike. Wannan lokacin ya kai 0.2 ms da 0.3 ms na piezo- da solenoid injector, bi da bi.

A kan ginshiƙi na piezo-injector, an gabatar da yanayin don hanzarta allura tare da matsa lamba a cikin ɗakin. Don Pinj = 60 MPa kawai wannan dabi'a ta bambanta, amma yanayi na iya yin tasiri. Injector na solenoid yana aiki a cikin hanyar da za a iya maimaitawa kuma matsa lamba na baya bai haifar da wani muhimmin bambanci a cikin lokacin jinkiri ba. A wannan yanayin, matsa lamba na allura shine abin da ya hanzarta yin allurar, kamar yadda aka riga aka lura don allurar piezo-injector. Abin da ya kamata a ambata shi ne gaskiyar, cewa sakamakon don injector solenoid daga Pinj a kan 60 MPa a mafi yawan lokuta ya bambanta ta hanyar ± 1 kawai, don haka dangane da daidaiton ma'auni ya kamata a bi da su azaman babu bambanci. Piezo-injector a ƙananan matsi na allura ya sami jinkirin jinkiri fiye da electro-injector, amma tare da karuwa a matsa lamba wanda aka juya baya. Ya kamata a lura cewa piezo-injector wani tsofaffin ƙira ne: injector na lantarki ya maye gurbin piezo-injector a cikin ƙirar masana'anta.

An gabatar da sakamakon jinkirin allurar na matsakaici da tsawon lokacin allura a cikin adadi na 6 da adadi 7, bi da bi. Ana iya kimanta aikin piezo-injector azaman ƙarin bazuwar. Dangane da kwatancen sakamakon za a iya bayyana, cewa matsa lamba na iska (matsa lamba na baya) yana da tasiri mai mahimmanci akan jinkiri kuma tasirin man fetur yana da iyaka. An sami sakamako mai kama da haka don injectors na solenoid, amma a cikin wannan yanayin mafi girman tasiri a kan jinkirin allurar yana da karfin man fetur kuma tasirin iska ba shi da kyau.
