PURPOSE: A system for reducing a temperature of fuel is provided to uniformly control an output of engine according to a change of temperature by cooling the fuel increased the temperature with a cool air of air conditioner to prevent a reduction of output efficiency in the engine by the increase of fuel temperature. CONSTITUTION: A supplying line of fuel(70) is closed if a temperature of fuel is over a set temperature. And a cooling line of fuel(10) is opened by supplying a power into a three-directional valve(30) with a thermo switch(20). The fuel flowed inside is cooled by touching a cold air passed a heat exchanger(12) on a surface of fuel cooling line(10). The fuel is supplied into a jetting nozzle(80) by passing a check valve(40), flowing into the supplying line of fuel(70) and passing a jetting pump of fuel(54). Thereby, the reduction of engine output according to a rising of fuel temperature is prevented by equaling the temperature of fuel supplied into a combustor.
