“…The electrical circuit provides input voltage to the coil to control plunger movement through electromagnetic force. The mechanical circuit describes the forces that apply to the plunger during its movement, as shown in equation (6). In order to simulate the operation of the solenoid injector with the equivalent circuits mentioned above, the Simplorer software is used as a solver.…”

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.

The fuel injection system is one of the key components of an in-cylinder direct injection engine. Its performance directly affects the economy, power and emission of the engine. Previous research found that the Taguchi method can be used to optimize the fuel injection map and operation parameters of the injection system. The electronic control injector was able to steadily control the operation performance of a high-pressure fuel injection system, but its control was not accurate enough. This paper conducts an experimental analysis for the fuel injection quantity of DI injectors using the Taguchi-Regression approach, and provides a decision-making analysis to improve the design of electronic elements for the driving circuit. In order to develop a more stable and energy-saving driver, a functional experiment was carried out. The hybrid Taguchi-regression algorithm for injection quantity of a direct injection injector was examined to verify the feasibility of the proposed algorithm. This paper also introduces the development of a high-pressure fuel injection system and provides a new theoretical basis for optimizing the performance of an in-cylinder gasoline direct injection engine. Finally, a simulation study for the fuel injection control system was carried out under the environment of MATLAB/Simulink to validate the theoretical concepts.
