Patent ID: 7938385

Claim:
A method that increases fuel efficiency in, and lowers pollutant-gas emission from, an internal combustion engine within a motorized vehicle, the method comprising: installing an on-board fuel-refining system within the motorized vehicle, the on-board fuel-refining system then drawing fuel from the fuel tank of the motorized vehicle, refining the fuel, and providing refined fuel to the internal-combustion engine; and monitoring the fuel efficiency of the internal-combustion engine and the output of various sensors in order to continuously adjust operational on-board-fuel-refining parameters in order to optimize fuel efficiency obtained by the internal combustion engine; wherein the on-board fuel-refining system comprises: a first reservoir; a lift pump that provides fuel to the first reservoir from the fuel tank of the motorized vehicle; a fuel-refining unit in which fuel is refined, the fuel-refining unit including a rotor driven by a motor, the rotor enclosed by a rotor-and-rotor-chamber housing that, together with the rotor, forms a rotor chamber in which fuel is subject to fluid-shear forces; a fuel-refining-unit pump that provides fuel from the first reservoir to the fuel-refining unit; and a second reservoir into which refined fuel output by the fuel-refining unit is introduced.
