A model-based study is conducted to develop a high-performance solenoid gas Injector applied for compressed natural gas (CNG) fueled engines. Operation of the solenoid gas Injector is described through mathematical models, Including mechanical and electrical models. The solenoid of the gas injector is modeled in Maxwell software to simulate its electromagnetic force in static mode, which is based on specifications of a real solenoid gas injector. The electromagnetic force along with flux obtained by the solenoid model in Maxwell is then imported into AMESim software to simulate the operating characteristics of the solenoid gas injector in transient mode, such as motion characteristics of the plunger, response time, and injection quantity. The electromagnetic force and operating characteristics of the solenoid gas injector are investigated under the effects of structural parameters, including core and sleeve shapes. The simulation results show that the electromagnetic force and open response time of the solenoid gas injector are significantly improved by changing the core and sleeve shapes.
