Binciken jihohi na wucin gadi na injin injectors na CI tare da amfani da hanyoyin gani(KASHI NA 5)

An gudanar da binciken don ƙima na sigogi na yau da kullun don aiki na yau da kullun na injin konewa na ciki. An ƙirƙiri shirin binciken tare da nufin tantance tasirin kowane siga akan lokacin jinkirin allurar. Kamar yadda aka zaɓi masu canji na tsari: matsa lamba na allura, matsa lamba na baya da tsawon lokacin allura. Ya kamata a lura cewa siga na ƙarshe ya sami ƙimar mafi girma don injector na solenoid saboda ƙarancin kwararar mai. Ana nuna kewayon bambancin sigogi a cikin tebur 2.

2.1. Binciken siginar lantarki A lokacin gwaje-gwaje, an yi rikodin sigogin lantarki (Figure 2). An yi amfani da wannan bayanan don ƙayyade jinkirin lokaci tsakanin motsin farawa da siginar lantarki mai dacewa (wanda aka auna a cikin injector tare da amfani da software na AVL Concerto). An zaɓi motsin farawa azaman farkon siginar sarrafa TTL don injector; An saita ƙarshen ƙarshen wannan binciken azaman lokacin da aka lura da martani akan matsi na yanzu. Bambanci tsakanin waɗannan maki biyu an sanya hannu a matsayin te kuma yana bayyana jinkirin kayan aikin a cikin tsarin allura. A cikin wannan bincike an ayyana lokacin td a matsayin lokacin daga farkon yunƙurin (na allura) zuwa martanin diode. Za a yi bayani dalla-dalla ma'anar wannan lokacin a cikin wannan babi.

3.4. Binciken gwaje-gwaje na gani Hotuna daga gwaje-gwaje na gani an yi nazari tare da amfani da software na DaVis daga LaVision. Hanyar nazarin hoto an bayyana shi a cikin adadi 3. An saita saurin rikodi akan 250 kfps tare da ƙudurin sararin samaniya na 128 × 16 pixels. Da farko, an cire bangon baya daga ƴanyen hotuna don cimma cikakkiyar hoto na ci gaban feshin mai. Hoton farko da aka bincika don tantance jinkirin allurar shine hoton tare da diode da ake gani a gefen hagu (hoto na uku a adadi 3). An saita lokacin filasha diode akan ƙimar 4µs, don haka yana yiwuwa a lura da diode akan firam ɗaya kawai. Mataki na gaba na binciken shine nemo firam inda pixels kusa da bututun injector suka canza matakin haskensu. Canjin haske yana nufin faruwar faɗuwar man fetur. An bayyana wancan lokacin da cewa.
