New Common Rail Fuel Injector F00RJ01683 Control Valve Assembly for Injector 0445120080 0445120268

Kuongororwa kwenhamba uye zvidzidzo zvekuyedza pane solenoid yakajairika njanji dizeli injector ine yakasakara yekudzora vharafu(chikamu1)

Abstract.

masvomhu modhi ye solenoid common rail fuel injector yakagadzirwa. Musiyano wayo kubva kumhando dziripo ndeye control valve kupfeka simulation. Yakajairika njanji jekiseni ye0445110376 Series (Cummins ISf 2.8 Diesel injini) yakagadzirwa neBosch Company yakashandiswa sechinhu chekutsvagisa. Injector parameters (kuunza mafuta uye kudonha kwemashure) kwakatemwa nekuverenga uye nzira dzekuyedza. GT-Suite modhi yeavhareji R2 i0.93 zvinoreva kuti inofanotaura chimiro chejekiseni nemazvo chaizvo (mazita uye mumucheto tekinoroji mamiriro ejekiseni). Kuongororwa kwenhamba uye zvidzidzo zvekuyedza zvakaratidza kuti kupfeka kwevharuvhu yekudzora kunowedzera kudonha nekuburitswa kwemafuta (kunyanya pa160 MPa). Mamodheru ekudzoreredza ekutarisa kuunza mafuta uye kumashure ekudonha mhedzisiro pakumanikidza kwemafuta uye nguva inosimbisa yakagadziridzwa (yezita uye marginal tekinoroji mamiriro).

Mota zhinji dzemazuvano dzine injini dzedhiziri dzine majekiseni akajairika enjanji. Ivo vanobatsira kuzadzisa zvakaomesesa zvinodikanwa zveexhaust gasi emission rates. Izvi zvinogoneka nekuda kwekukura kwemafuta ekumanikidza (kusvika 300 MPa) uye kushandiswa kwemafuta ebiodiesel [1-4]. Yakajairika njanji mafuta majekiseni ndiwo anonyanya kukosha eiyo system [5]. Vanobvumira kuendeswa kwemafuta mumasilinda nehupamhi hwepamusoro zvichienderana neinjini yekushandisa mode. Kune marudzi maviri emajekiseni - ane piezo actuators uye ane solenoid actuators [6-8]. Mumwe nemumwe wavo ane zvimwe zvakanakira uye nekuipa [9]. Pasinei nerudzi rwejekiseni rinoshandiswa, kurongeka kwemafuta kunofanirwa kupihwa kwenguva yakareba. Mamiriro ehunyanzvi eyakajairwa njanji mafuta jekiseni system inoshanduka nekuwedzera kwemotokari mileage [10].
