Design and analysis of multi fuel injector

Abstract

Abstract In accordance with strict emission norms, the depletion of fossil fuels requires a fuel injection system that is efficient, responsive, and adaptable to various locally available fuels. Hence, electronically controlled fuel injector technology is the best option for fulfilling this requirement. Commercially, there are various types of fuel injectors which are mainly used for specific fuels such as gasoline, diesel, CNG, LPG, etc. This research outlined in this paper is based on the design of a multi-fuel injectorwhich will be compatible to both gaseous and liquid fuels as a tremendous volume of research has been done in the usage of alternative fuels like hydrogen, JP-8, biogas, producer gas, acetylene, alcohol, and biodiesel. Since the government is primarily focused on green fuels and biogas fuels, the design of such a type of injector will become an excellent opportunity for the design of new products that will be compatible with automobile engines, gas-turbines, aerospace combustion furnaces, gas stoves, etc. An electronically controlled solenoid-operated multi-fuel injector was designed by utilizing the properties and parameters of liquid and gaseous fuel injectors. The designed Multi-fuel injector was modeled in Solid Works and simulated in ANSYS software. The simulated injector was tested with fuels, including gasoline, CNG, and acetylene. Due to a pressure limitation of 5 bar, the designed injector was tested only for low viscous fuels. The injector worked in the velocity range of 70 to 100 m/s. The usage of the Solenoid coil control enabled the injector to function with quick response, injected fuel quantity, and start of injection for various fuels.
