Abstract
Abstract An insulated coil (20) of wire (23) of a prescribed length and number of turns is positioned to surround a linearly-extending portion of a metal or plastic fuel conduit (10) associated with an internal combustion engine or conduit transporting a burner gas to a stove burner or furnace. The coil core (22) may be electrically conductive wire which is surrounded by electrical insulation or liquid electrolyte (31) contained in plastic tubing (30) which tubing is coiled around the fuel conduit (10). The use of the device is shown to increase the miles per gallon of fuel performance of an auto and to improve combustion emissions. In gas burner applications, the number of days of use from a standard volume gas cylinder has been substantially increased when the device is used.
