A fuel pump for a liquid fuel water injection system of a motor vehicle is provided. The fuel pump includes a low-pressure pump that mixes water from a water tank of the motor vehicle with liquid fuel from a fuel tank of the motor vehicle to a liquid fuel water emulsion and provides the liquid fuel water emulsion at a low pressure. A high-pressure pump is in fluid communication with the low-pressure pump and compresses the liquid fuel water emulsion from the low pressure to a high pressure for injecting the liquid fuel water emulsion into an internal combustion engine of the motor vehicle via an injection rail of the motor vehicle. A pump drive drives the low-pressure pump and the high-pressure pump synchronously with a pump frequency independently from an engine speed of the internal combustion engine of the motor vehicle.

A method for preparing a stabilized assembly includes combining a first liquid phase including nanoparticles and a second, immiscible liquid phase, dissolving in the second phase a first end-functionalized polymer having a first molecular weight, and a second end-functionalized polymer having a second molecular weight, wherein the second molecular weight is greater than the first molecular weight, applying a shearing external deformation field to increase the surface area of the first phase to create a new interface, wherein the nanoparticle surfactants form a disordered, jammed assembly at the new interface, and releasing the shearing external deformation field. The polymer and the nanoparticles can interact at an interface through ligand interactions to form nanoparticle surfactants and upon releasing the external deformation field the jammed assembly at the new interface traps the first phase in a deformed state having the first liquid phase and the second liquid phase as interpenetrating domains.

The manufacturing method for an emulsion of the present invention is a manufacturing method for an emulsion, including circulating a mixed liquid containing a water phase and an oil phase in a circulation circuit including a plurality of tanks, a porous body, a liquid-delivering means, and circulation pipes configured to connect the tanks, the porous body, and the liquid-delivering means so that the mixed liquid passes through the porous body a plurality of times, wherein a tank to supply the mixed liquid to the circulation pipes toward the porous body and a tank to recover the mixed liquid that has passed through the porous body are different tanks.

A progressive shear emulsifier can include an outer body and an inner body. The outer body can have a central opening therethrough, an inlet, an outlet, and an inner surface along the central opening defining a first three-dimensional contour. The inner body can be positioned within the central opening and configured to rotate with respect to the outer body about an axis of rotation along the central opening. The inner body can have an outer surface defining a second three-dimensional contour that correlates to the first three-dimensional contour to form a material passage between the outer body and inner body. Rotation of the inner body within the outer body can create progressive amounts of shear across materials passing through the material passage, which can result in emulsified material. Conic transitions can create turbulent regions that mix the materials passing therethrough. Collective geometry can create conveyance and/or pumping of materials, which can be methylcellulose and free water.

One or more suction tanks may be fluidly coupled to the one or more liquid-liquid ejectors; the one or more suction tanks may supply the one or more liquid-liquid ejectors with a suction fluid. One or more discharge tanks may be fluidly coupled to the one or more liquid-liquid ejectors; the one or more discharge tanks may collect an emulsion from the one or more liquid-liquid ejectors. Additionally, a flow line coupled to the one or more discharge tanks may feed the emulsions into a formation.
