A model-based study is carried out based on a combination of mathematical and Maxwell models to develop a high-performance electric pressure regulator utilized for compressed-natural-gas-fueled vehicles. To reduce computational cost, a symmetric two-direction model of the electric pressure regulator is established in Maxwell software, in which its material properties and dimension parameters are obtained on the base of specifications of a real electric pressure regulator. The output of simulating in Maxwell is the electromagnetic force, which is significantly improved when changing core shape in the various dimensions ∆1, ∆2, and ∆3. The optimal electromagnetic force is utilized for the mathematical models as an input variable to simulate the operational characteristics of the electric pressure regulator such as displacement and response time of plunger. The operational characteristics of the electric pressure regulator are examined under the influences of key parameters, including inlet gas pressure, diameter of orifice, and spring stiffness. By optimizing these key parameters, the simulated results in this study show that an electric pressure regulator with high performance can be obtained.

On July 6, 2009, the world's first commercial single compressed natural gas (CNG) fueled ship, M.V. NP Jenjosh—the first of 12 contracted vessels built in Dajiang and Hongyu shipyards located in Wuhu city of Anhui Province, P.R. China and classed to China Classification Society (CCS)—was delivered to the owner, Jenjosh Group based in Thailand. This paper contains some technical discussions that took place during the class plan review of the subject vessels, including: hull technical practices, machinery, and electrical technical practices, and also discusses designing the similar CNG fueled ships and developing the international gas-fueled (IGF) ship code in future. Finally, this paper draws conclusions and looks forward to the future practice of the CNG fueled ship.

A model-based study was conducted to examine the effects of plug shape on electromagnetic force and dynamic response of an electric pressure regulator (EPR) applied for gaseous fueled vehicles. Mathematical models were established to describe the operation of the EPR, including mechanical and electrical models. A two-dimensional (2D) symmetric model of the EPR was built in Maxwell software to simulate the electromagnetic force under the effects of plug shape. Afterward, the 2D symmetric model of EPR with the electromagnetic force calculated was imported into Simplorer software to simulate the dynamic response of the EPR based on the influence of plug shape. The shape of plug in the EPR was changed through the dimension parameters denoted by dimension (h) and slope angle (). The simulation results show that the electromagnetic force and dynamic response of the EPR can be optimized when h and  are selected at 3mm and 480, respectively.
