I-Common Rail Fuel Injector Control Valve Assembly F00RJ01052 ye-Injector 0445120028 0445120069

Ukuhlaziywa kwe-Transient states kwama-injection enjini ye-CI kusetshenziswa izindlela zokubona(INGXENYE 5)

Uphenyo lwenziwa ngamavelu amapharamitha ajwayelekile okusebenza okuvamile kwenjini evuthayo yangaphakathi.Uhlelo locwaningo lwakhiwe ngenhloso yokunquma umthelela wepharamitha ngayinye ngesikhathi sokulibaziseka komjovo.Njengoba okuguquguqukayo kwenqubo kukhethiwe: ingcindezi yomjovo, ingcindezi yangemuva kanye nobude besikhathi sokujova.Kufanele kuqashelwe ukuthi ipharamitha yokugcina kufanele ithole inani eliphakeme lomjovo we-solenoid ngenxa yezinga eliphansi lokugeleza kukaphethiloli.Ububanzi bokuhlukahluka kwamapharamitha buboniswa kuthebula 2.

2.1.Ukuhlaziywa kwesignali kagesi Ngesikhathi sokuhlolwa, imingcele kagesi yabhalwa (umdwebo 2).Le datha yasetshenziselwa ukunquma ukubambezeleka kwesikhathi phakathi komfutho oqalayo nesignali kagesi efanele ( ikalwe kumjovo kusetshenziswa isofthiwe ye-AVL Concerto).Umfutho wokuqala ukhethiwe njengesiqalo sesiginali yokulawula ye-TTL yomjovo;iphuzu lokugcina lalokhu kuhlaziya labekwa njengesikhathi lapho impendulo kuma-clamp amanje yabonwa.Umehluko phakathi kwalawo maphuzu amabili usayinwe njenge-te futhi uchaza ukubambezeleka kwehadiwe ohlelweni lomjovo.Kulokhu kuhlaziya isikhathi se-td sichazwe njengesikhathi kusukela ekuqaleni komfutho (komjovo) ukuya ekuphenduleni kwe-diode.Incazelo yalesi sikhathi izochazwa kabanzi kulesi sahluko.

3.4.Ukuhlaziywa kokuhlolwa kokubona Izithombe ezivela ekuhlolweni kokubona zahlaziywa kusetshenziswa isoftware ye-DaVis evela kuLaVision.Indlela yokuhlaziywa kwesithombe ichazwe emfanekisweni 3. Ijubane lokurekhoda lalibekwe ku-250 kfps ngokulungiswa kwendawo yamaphikseli angu-128 × 16.Ekuqaleni, ingemuva likhishwe ezithombeni ezingavuthiwe ukuze kuzuzwe isithombe esicacile sokuthuthukiswa kwesifutho sikaphethiloli.Isithombe sokuqala esihlaziywe ukuze kutholwe ukubambezeleka komjovo kwakuyisithombe esine-diode ebonakalayo ohlangothini lwesobunxele (isithombe sesithathu kumfanekiso 3).Isikhathi sokukhanya kwe-diode sasisethwe kunani lika-4 µs, ngakho-ke bekungenzeka ukubuka i-diode kuhlaka olulodwa kuphela.Isinyathelo esilandelayo sokuhlaziya bekuwukuthola ifreyimu lapho amaphikseli aseduze nombhobho wokujova ashintshe izinga lawo lokukhanya.Ukushintsha kokukhanya kusho ukwenzeka kwamaconsi kaphethiloli.Leso sikhathi sachazwa ngokuthi.
