I-Common Rail Fuel Injector entsha F00RJ01683 Control Valve Assembly for Injector 0445120080 0445120268

Ukuhlaziywa kwezinombolo kanye nezifundo zokuhlola kumjovo we-solenoid wesitimela ovamile one-valve yokulawula egugile(ingxenye1)

Abstract.

imodeli yezibalo ye-solenoid common rail fuel injector yasungulwa.Umehluko wayo kumamodeli akhona uwukulinganisa kokugqoka kwe-valve.Umjovo wesitimela ojwayelekile ongu-0445110376 Series (injini ye-Cummins ISf 2.8 Diesel) okhiqizwe yi-Bosch Company wasetshenziswa njengento yocwaningo.Amapharamitha omjovo (ukulethwa kukaphethiloli nokuvuza emuva) anqunywa ngokubala nezindlela zokuhlola.Imodeli ye-GT-Suite eyisilinganiso esingu-R2 ngu-0.93 okusho ukuthi ibikezela umumo wezinga lomjovo ngokunembe kakhulu (izimo zobuchwepheshe ezivamile nezincane kakhulu zomjovo).Ukuhlaziywa kwezinombolo kanye nocwaningo lokuhlola lubonise ukuthi ukugqokwa kwamavalvu okulawula kwandisa ukuvuza emuva kanye nokulethwa kukaphethiloli (ikakhulukazi ku-160 MPa).Amamodeli okuhlehla okunquma ukulethwa kukaphethiloli kanye nemiphumela yokuvuza emuva kumfutho kaphethiloli kanye nesikhathi sokunika amandla athuthukiswa (ngezimo zobuchwepheshe ezivamile nezincane).

1. Isingeniso

Izimoto eziningi zesimanje ezinezinjini zikadizili zifakelwe amasistimu omjovo wamafutha kaloliwe ajwayelekile.Zisiza ukuhlangabezana nezidingo eziqinile zamazinga okuphuma kwegesi ephumayo.Lokhu kungenzeka ngenxa yokukhiqiza uphethiloli ophezulu (kuze kufike ku-300 MPa) kanye nokusetshenziswa kukaphethiloli we-biodiesel [1-4].Ama-injection kagesi kaloliwe ajwayelekile ayizingxenye ezibaluleke kakhulu zesistimu [5].Bavumela ukulethwa kukaphethiloli kumasilinda ngokunemba okuphezulu kuye ngemodi yenjini yokusebenza.Kunezinhlobo ezimbili zama-injection - ane-piezo actuators kanye nama-solenoid actuators [6-8].Ngamunye wabo unezinzuzo ezithile kanye nokubi [9].Kungakhathalekile ukuthi hlobo luni lomjovo osetshenzisiwe, ukunemba okuphezulu kokulethwa kukaphethiloli kufanele kuhlinzekwe isikhathi eside impela.Izimo zobuchwepheshe zesistimu yomjovo kaloliwe ojwayelekile ziyashintsha ngokukhuphuka kwemayela lemoto [10].
