LIQUID FUEL PROCESSING DEVICE

Provided is a liquid fuel processing device which can sharply reduce hazardous substances contained in exhaust gas discharged from a thermomotor. A liquid fuel processing device (10) arranged above a channel (26) for supplying liquid fuel to a thermomotor has a plurality of magnetic action walls (50a, 50b) which are arranged on an appropriate interval on the channel (26), wherein the upstream side surface of the channel (26) in the magnetic action walls (50a, 50b) consists of a magnet having S pole magnetism of 0.2-1.5 mT and therefore the S pole magnetism can be made to act efficiently on the liquid fuel. Thus, combustion efficiency of a thermomotor such as a diesel vehicle, a gasoline vehicle, an LP gas vehicle, a vessel, a boiler, or the like, is enhanced and energy saving effect can be attained while sharply reducing all hazardous substances such as CO2, CO, HC, NOx, PM, and the like in the exhaust gas.
