Numerical Analysis and Optimal Design on the Electromagnetic Fuel Delivery Regulating Actuator of Common Rail System

To study electromagnetic actuator used in common rail fuel injection system, AMESim software was applied to establish mechanical, fluid dynamic and electromagnetic valve models. Impacts of main factors on the system performance were figured out by simulation, including mechanism, hydraulic pressure and driving. Important design principles on electromagnetic fuel delivery regulating actuator were put forward. This method has been applied on a certain fuel delivery regulating actuator to accomplish its optimizing design.
