“…The dynamic performance of direct-acting solenoid valves has been studied since the late 1990s. However, since the so-called "green car" is globally under the spotlight, the dynamic performance of direct-acting solenoid valves is gaining more attention, and related research is actively being conducted [4].…”

Direct-acting solenoid valves are used in the automotive industry due to their simple structure and quick response in controlling the flow of fluid. We performed an optimization study of response time in order to improve the dynamic performance of a direct-acting solenoid valve. For the optimal design process, we used the commercial optimization software PIAnO, which provides various tools for efficient optimization including design of experiments (DOE), approximation techniques, and a design optimization algorithm. 35 sampling points of computational experiments are performed to find the optimum values of the design variables. In all cases, ANSYS Maxwell electromagnetic analysis software was used to model the electromagnetic dynamics. An approximate model generated from the electromagnetic analysis was estimated and used for the optimization. The best optimization model was selected using the verified approximation model called the Kriging model, and an optimization algorithm called the progressive quadratic response surface method (PQRSM).

“…The variable valve timing (VVT) changes camshaft phase of intake valve with respect to exhaust valve while variable valve lift (VVL) provides different valve displacements. The VVT controls valve independent of crank angle thus results in reduction in CO2 emission by 20%, an improvement of 15% in fuel economy, an improved torque output of 10% and HC (Hydrocarbon) emission at cold start is reduced by 50% [1][2][3][4][5][6][7][8][9].…”

“…Therefore at start-up the armature is latched to solenoid and is not at equilibrium position. The HVA with rectangular core, PM, and non-asymmetric armature is studied [3][4][5][6][7][8]. Rectangular core HVA requires precise motion of armature stem to prevent failure of operation.…”

Abstract. This paper proposes a novel hybrid valve actuator (HVA) with permanent magnet (PM) and electromagnet (EM) magnetomotive force (MMF) for variable valve timing camless engine. Traditional double solenoid valve actuator (DSVA) has inherent problem of high power consumption, as armature is at equilibrium position away from electromagnet therefore to move armature to open/close position and for keeping armature latched to EM. Hybrid PM/EM valve actuator is proposed in this study. The finite element analysis is performed with Ansys Maxwell on static characteristics of traditional DSVA and HVA on bases of actuator holding force. The equivalent model of static analysis is introduced into Ansys Simplorer for dynamic analysis. The simulation results depict reduce power consumption and transition time of proposed HDSVA over DSVA.
