Abstract
A fuel filter heating device may include an exhaust gas pipe through which exhaust gas generated from an engine flows, a heat transfer medium, which is disposed near a fuel filter to receive radiation heat transferred from the exhaust gas pipe and transfer the radiation heat to the fuel filter upon contacting the fuel filter, and a temperature-sensitive actuator for moving the heat transfer medium in a selected direction depending on the temperature of fuel in the fuel filter such that the heat transfer medium contacts the fuel filter to heat the fuel in the fuel filter or the heat transfer medium is separated from the fuel filter to block heat transfer therebetween.
