Abstract: Modern petrol engines demand lightweight, compact, fast-acting fuel-injectors. There has been an increasing focus in recent years on the development of automotive fuel injector solenoids that would allow reduction in size while not compromising their performance. The main objective of this research is to develop a specific virtual design approach capable of reducing the size of the fuel injector solenoid while improving its response time and attraction force. The simplicity and effectiveness of the developed virtual design methods allow for quick and accurate evaluation of alternative fuel injector designs early in the design and development stage.

Keywords: electromechanical; modelling; control; fuel injectors; solenoid actuators; actuating force; response time; vehicle design; automotive solenoids; virtual design; size reduction; fuel injector design.
