This paper discusses a new concept of an electronically controlled hydrogen injector for a multipoint injection system for a Wankel engine. This injector can be designed with the use of CFD (Computational Fluid Dynamics) methods, the AVL Fire software to optimise injector geometrical parameters, and magnetic field simulations to optimise an electromagnetic coil. Prototype injector test stand research, the current voltage and intensity in an electrical circuit are analysed to determine lag times for opening and closing an injector valve. Also, the impact of supply pressure for the operating parameters (opening time, closing time) and the pressure in an injector nozzle are analysed. Finally, injector flow characteristics as a function of injection time is developed. The paper supports the hypothesis that the value of supply pressure can increase injector opening lag time. At the same time, higher supply pressure can decrease lag delay time for valve closing. The reference flow rate to ensure a proper supply in the Wankel engine tested has been achieved.
