Genetic Algorithm-Based Design Optimization of Electromagnetic Valve Actuators in Combustion Engines

Abstract

Abstract:In this research, the design of a new electromagnetic engine valve in the limited space of combustion engine is optimized by multidisciplinary simulation using MATLAB and Maxwell. An electromagnetic engine valve actuator using a permanent magnet is a new actuator concept for overcoming the inherent drawbacks of the conventional solenoid-driven electromagnetic engine valve actuator, such as high power consumption and so on. This study aims to maximize the vibration frequency of the armature to reduce the transition time of the engine valve. The higher performance of the new actuator is demonstrated by dynamic finite element analysis.

Lumped parameter modeling of hybrid magnetomotive force electromechanical valve actuator

“…The power consumption required to overcome the spring force and latching the armature at the seat, can be avoided by using a permanent magnet (PM). PM reluctance latches the armature without current requirement [7], [13] and [14]. A hybrid valve actuator (HVA) consisting a non-asymmetric armature and rectangular core has been studied [15], [16], [12], [17] and [18].…”

A Novel Design Concept of Electromagnetic Valve Actuator with High Starting Force

“…Promising candidates for fully independent valve system are electromagnetic based valve actuators [2][3][4]. Most popular among the proposed electromagnetic valve actuation solutions is the Pischinger EMV system [5,11]. The later versions of the valve actuator systems were upgraded with a permanent magnet core [2][3][4].…”

“…The later versions of the valve actuator systems were upgraded with a permanent magnet core [2][3][4]. In addition to this system, there are many other electromechanical solutions and most of them have integrated permanent magnets [11,12]. However, the actuators having permanent magnets are expensive and they may be problematic when used in harsh physical environments with extremely high or low temperatures [13] as well as humidity and vibrations.…”

“…This challenge in independent ICE valve electromagnetic control is being approached by developing an electromagnetic valve actuator design with an appropriate force-stroke characteristic, which would enable a high level of flexibility in valve timing control and lifting [2,5]. However, so far finding an appropriate solution for successful electromagnetic valve timing control has been a demanding task due to the pronounced nonlinearity of the force stroke characteristic and high landing velocity [2,4,11,12,[16][17][18][19][20].…”

Analysis, Design and Dynamic Simulation of Novel Limited Swing Angle Torque Permanent Magnet Motor for High Voltage Circuit Breaker Application

“…These traditional actuators are mostly assembled by complex drive gears and many components, which require a difficult fabrication process and result in an uncontrollable movement process. Therefore, the circuit breaker of a permanent magnet actuator, which has a small volume and fewer components, as well as a simple and reliable structure, is studied [9][10][11].…”
