Abstract

Green vehicles include electric vehicles, natural gas vehicles, fuel cell vehicles (FCV), and vehicles running on fuel such as a biodiesel or an ethanol blend. An FCV is equipped with a cylinder valve installed in an ultra-high pressure vessel to control the hydrogen flow. For this purpose, an optimum design of the solenoid actuator is necessary to ensure reliability when driving an FCV. In this study, an electromagnetic field analysis for ensuring reliable operation of the solenoid actuator was conducted by using Maxwell V15. The electromagnetic field analysis was performed by magneto static technique, according to the distance between magnetic poles, in order to predict the attraction force. Finally, the attraction force was validated through comparison between the Maxwell results and measurement results. From the results, the error of attraction force ranged from 2.33 to 3.85 N at testing conditions.

Summary

Introduction

In recent years, growing concerns regarding environmental pollution have recently increased the demand for green vehicles. It is composed of a manual manipulation device for opening and closing the flow path, a solenoid actuator, a temperature sensitized pressure relief device, and an overflow blocking device to secure safety against leakage and fire. There are growing demands injection systems of internal combustion engine are using solenoid actuators for reduction of fuel for high frequency response,exhaust reduction of actuation andgrowing strong anti‐pollution capabilities of consumption and hazardous emissions [5,6]. Solenoid actuator design requires the necessary maximum for cylinder valve applications has been the focus of research recently, and it is one of the key attractive force safety actuator factors, magnetic flux density analysis,maximum the shape attractive of the solenoid technologies of considering. Performance evaluation tests were conducted to validate the actuator
