POWER CONSUMPTION OF ELECTRODYNAMIC VALVE ACTUATOR

Abstract

: The presented analysis deals with a procedure how to compute electric energy consumption of electrodynamic valve actuator of combustion engine. The main aim of the electrodynamic valve control is to ensure independent valve lift and timing. Magnetic field of the actuator was determined using finite element analysis software. The paper also deals with an optimizing of the actuator coil. Forces from the flue-gas acting on valve is included in this model. Valve lift, coil current, voltage and electric energy consumption are graphically shown.
