Can Electrorheaology Boost Mileage?

Directory page for Electro - Rhealogy technologies and resources.

Rheology is defined as the science of the deformation and flow of matter. This involves the study of what can informally be called "funny fluids" and soft solids. In theory it could include the study of all materials that deform or flow but, by convention, classical (Hookean) elastic solids and viscous (Newtonian) liquids are excluded. Both non-Newtonian and elastic liquids and viscoelastic solids are included in the science.

Resent research by researchers at Temple University in Philadelphia suggest a method by which electrorheology could be used to 'boost fuel efficiency by up to 20%'. Their small device consists of an electrically charged tube that can be attached to the fuel line of a car's engine near the fuel injector. With the use of a power supply from the vehicle's battery, the device creates an electric field that thins fuel, or reduces its viscosity, so that smaller droplets are injected into the engine. That leads to more efficient and cleaner combustion than a standard fuel injector.

:"Scientists and engineers are most familiar with single-crystal or polycrystialline field-responsive materials responses typically occurring while the materials remain in the solid state. These materials demonstrate dramatic changes in their rheological properties including yield stress, loss and storage moduli etc. in response to an externally applied electric or magnetic field are known as electrorheological fluid (ERF) or magnetorheological fluid (MRF), respectively." (Jong Hyeok Park and O Ok Park

:In contrast to electro-rheological (ER) fluids, magneto-rheological (MR) fluids:

:Are 20-50 times stronger

:Are significantly less sensitive to contaminants and extremes in temperature

:Can be operated directly from low-voltage power supplies

:MR technology can provide flexible control capabilities in designs that are far less complicated and more reliable than those based on ER technology. (Lord)
