Reduction of Valve Seating Velocity in Electro Hydraulic Valve Actuation System
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 2
Abstract
The engine has two valves one in the inlet and other in the outlet. The valve timing is a significant thing of the engine. The valve actuation system is of two different types (1) Cam Based and (2) Camless Based actuation system. Initially valves were actuated by cam based system. Since these systems are mechanical, the performance diminishes overtime. To overcome this disadvantage and for accurate valve timing came the cam less actuation system. The electro hydraulic variable valve actuation system is one of the popular cams less actuation system in which the rotary spool valve is controlled by PI controller. The valve seating velocity is defined as the linear motion of the valve. The valve seating velocity is not optimized for good performance in the real engine. Hence we propose a system to optimize the valve seating velocity. The proposed system is modeled using bond graphs and the outputs are verified.
