In this study, a novel design concept of magnet-less, high response time electromagnetic valve actuator with high starting force for independent valve actuation control of internal combustion engines is proposed. The new actuator geometry design is based on the theoretical analysis of electromagnetic and mechanical properties of a curve shaped object rolling on a fixed surface, which may be either flat or curved. The prototype of the new electromagnetic valve actuator was built according to the results that were obtained with finite element based numerical modelling and analysis. Finally, the experimental measurements are performed and the theoretical predictions were confirmed by obtaining good agreement between the experimental and numerical simulation results.
