Effect of Alternating Magnetic Field-Based Preprocessing Equipment on Fuel Atomization.

This study investigates the fuel atomization effect of alternating magnetic field (AMF)-based preprocessing equipment that promotes the atomization of automobile fuel. Two coils are connected to the output terminal of the preprocessing equipment and wound on an STS 316 L fuel pipe in the form of a solenoid. Positive sine waves and negative sine waves are output to the two coils, and the AMF in the solenoids causes atomization of the fuel flowing inside the pipe. A spray visualization experiment was conducted with fine particles sprayed from the injector, and the spray arrival distance, spray angle, and spray area were recorded. The information was analyzed to digitize the spray penetration, angle, and area at 2 ms after firing the injector. The fuel atomization effect of the AMF-based preprocessing equipment was also investigated Gasoline was used as the fuel, and the fuel atomization effect was analyzed using the number of windings around the STS 316 L fuel pipe, the frequency applied to the coil, the distance between the two solenoid coils, and the fuel injection pressure as variables.
