I-Common Rail Fuel Injector Control Valve Assembly F00VC01386 yama-Injector 0445110387 & 0445110388

Ukuhlaziywa kwe-Transient states kwama-injection enjini ye-CI kusetshenziswa izindlela zokubona(INGXENYE 7)

Kuwo womabili ama-injection ukubambezeleka kokuphendula kwehadiwe kuthathwa njengokujwayelekile futhi kungu-0.012 ms we-piezo- kanye no-0.016 womjovo we-solenoid. Njengoba isignali yokukhanya kwe-diode ivela kuhlaka olufanayo ngemva kokuqala kokulinganisa ngakunye, kungase kuthiwe izilinganiso zizinzile futhi ziyaphindaphindeka. Umfanekiso wesi-5 uveza isikhathi esifushane sokunika amandla kuzo zombili izinhlobo zamajoyi, njengoba kwase kushiwo endleleni yocwaningo. Lesi sikhathi silingana no-0.2 ms no-0.3 ms we-piezo- kanye nomjovo we-solenoid, ngokulandelanayo.

Eshadini le-piezo-injector, ukuthambekela kokusheshisa umjovo ngokucindezela okuphezulu ekamelweni kwethulwe. Ku-Pinj = 60 MPa kuphela lokhu kuthambekela kuhlukile, kodwa kungase kuthonywe izimo ezingahleliwe. Umjovo we-solenoid ubusebenza ngendlela ephindaphindwayo futhi ingcindezi engemuva ayenzanga noma yimuphi umehluko obalulekile ngesikhathi sokulibaziseka. Kuleso simo ukucindezela komjovo kwakuyisici esasheshisa umjovo, njengoba wawusuvele uqashelwe ngomjovo we-piezo. Okufanele kukhulunywe ngakho iqiniso, ukuthi imiphumela yesijovo se-solenoid esivela ku-Pinj ngaphezu kuka-60 MPa ezimweni eziningi ihluka ngohlaka olu-±1 kuphela, ngakho-ke ngokuya ngokunemba kokulinganisa kufanele ithathwe njengongekho umehluko. I-Piezo-injector ekucindezelweni komjovo okuphansi ithole ukubambezeleka okuphansi kunomjovo we-electro-injector, kodwa ngokunyuka kwengcindezi ehlehlisiwe. Kufanele kuqashelwe ukuthi i-piezo-injector iyidizayini endala: i-electromagnetic injector ithathe indawo ye-piezo-injector kumadizayini womkhiqizi.

Imiphumela yokubambezeleka komjovo ubude besikhathi somjovo omaphakathi nesikhathi eside uvezwa kumfanekiso 6 nomfanekiso 7, ngokulandelana. Umsebenzi we-piezo-injector ungase uhlolwe njengokungahleliwe. Ngokwesisekelo sokuqhathaniswa kwemiphumela kungashiwo, ukuthi umfutho womoya (i-back-pressure) unethonya elibaluleke kakhulu ekubambezelekeni kanye nomthelela wokucindezela kukaphethiloli kuncane. Imiphumela efanayo kakhulu yafinyelelwa kuma-solenoid injector, kodwa kulesi simo umthelela omkhulu ekubambezelekeni komjovo ube nomfutho kaphethiloli kanye nomthelela womfutho womoya wawungekho.
