| Popis: | The conventional mechanical driven valve train for the internal combustion engines has difficulty to handle the various valve events. In this paper, an electromechanical actuated valve train system is developed to provide a more efficient option for valve timing management. The details of the mechanical design of the valve have been discussed, as well as the control system. A prototype of the valve actuation system has been built to verify the design. The testing has shown that the prototype system can actuate the valves to any desired timing at a maximum reliable speed of 3,000 RPM without soft seating, and achieve a partial soft seating at an engine speed of 500 RPM. |
