“…14 The gaseous fuel direct injectors require new technology to adapt to high-pressure gas injection and precision. Recently, there have been many investigations of solenoid-type gasoline and diesel injectors, [15][16][17][18][19][20][21][22][23][24][25][26] but there are very few investigations of gaseous fuel injectors using electric solenoids. Therefore, gaseous fuel injectors using electric solenoid valves ought to be investigated further.…”

Purpose of this study is to develop a solenoid actuator that can be used for natural gas injector. Operation of the solenoid injector is described by two mathematical models including an electrical model and a mechanical model. The solenoid injector is also modeled and simulated in Maxwell and Simplorer based on the specifications of a real solenoid injector. The operating characteristics of the solenoid injector, including the current, electromagnetic force, and displacement of the plunger, are investigated under the effects of input parameters. In addition, experimental systems are established to examine the electromagnetic force and the plunger displacement in the solenoid injector under the effects of air gap and input voltage, respectively. The simulation results show that the electromagnetic force and displacement of the plunger can be easily increased by reducing the length and increasing the width of the cross-sectional shape of the coil. In addition, the increased length and diameter of plunger also contribute to improving the electromagnetic force. The increase in plunger mass results in fluctuating plunger displacement, which can affect the quality of injection. The simulation results are validated by experimental results on the effects of air gap and input voltage.

“…Xie et al [12] found that driving strategy is one of the most important factors affecting power loss and thermodynamic characteristics of HSV, with power loss being the main heat source that raises coil temperature. At the same time, temperature rise reduces magnetic flux density and weakens magnetic induction intensity of HSV, increasing total energy loss significantly and affecting durability of HSV [13]. Therefore, considering service life, energy loss characteristics need to be taken into account when optimizing HSV.…”

Under high-frequency operating conditions, the high-speed solenoid valve (HSV) experiences energy loss and heat generation, which significantly impact its operational lifetime. Reducing the energy loss of HSV without compromising its opening response characteristics poses a significant challenge. To address this issue, a finite element simulation model of HSV coupled with a current feedback model is constructed to investigate the synergistic effects of dynamic response and energy loss. Predictive models for the opening response time, HSV driving energy, and Joule energy using Back Propagation neural network (BPNN) are established. Furthermore, a multi-objective optimization study on the current driving strategy using Non-dominated Sorting Genetic Algorithm II (NSGA-II) is conducted. After optimization, although there was a 6.24% increase in the opening response time, both HSV drive energy and Joule energy were significantly reduced by 15.67% and 22.49%, respectively. The proposed multi-objective optimization method for HSV driving strategy holds great significance in improving its working durability.
