Abstract:
The intake and exhaust valves in an internal combustion engine (IC) have been traditionally operated by a mechanically driven camshaft, the valve mechanisms have improved over long years. They became more versatile, the electromechanical valve (or electromagnetic valve) provides improvements in engine efficiency, fuel consumptions, emissions, and performance by changing the valve lift and valve timing as a function of engine operating conditions. In an electromagnetic valve train (EMV), actuator replaces the camshaft and tappet from conventional engine. The electromagnetic actuator contains two electromagnets (solenoids), an actuator spring and an armature. However, the aim of this paper is to investigate experimentally electromagnetic valve train performance and vibration characteristics. For this reason, a special test rig was designed to evaluation electromagnetic valve train performance. The vibration responses were measured on the valve face at different operating conditions.The experimental results show the dynamic behavior of the (EMV) train system. The reasonable power consumption and energy of (EMV) valve are obtained with the design.
