Abstract: A system for improving efficiency of an internal combustion engine includes an electronic controller generating an RF signal and an electrolysis reactor electrically connected to the electronic controller. The electrolysis reactor includes a plurality of substantially parallel plates arranged in a stack. The plurality of plates includes a central positive plate, a first positive end plate, and a second positive end plate. The plurality of plates also includes a first negative plate located in the stack equidistantly between the central positive plate and the first positive end plate, and a second negative plate located in the stack equidistantly between the central positive plate and the second positive end plate. The plurality of plates further includes a plurality of neutral plates. The system also includes an aqueous solution flowing through the electrolysis reactor, the solution containing an electrolyte.
