Abstract
The paper deals with mathematical modeling and numerical computing of electromagnetic valve actuator. It describes the computing method for an internal combustion engine valve mechanism. The presented approach considers real magnetic material of electromagnets. The mathematical model reflects the B-H characteristic of the core and movable armature and deals with losses of magnetic material. The controlled current in the electromagnet coil prevents the valve bouncing from its seat. Forces from the flue-gas acting on the valve are included in this model. Valve lift, coil current, voltage and electric energy consumption are graphically shown.
