PURPOSE:To enable an overheating preventive countermeasure for a fuel distributing system to be performed without increasing an external size but restricting an increased cost by a method wherein a condensed water guiding means for flowing on a surface of fuel feeding pipe for an engine is provided to flow condensed water generated on a surface of an evaporator. CONSTITUTION:Condensed water naturally generated due to condensation of water vapor in air on a cold surface of an evaporator 4 constituting a refrigerating cycle is guided onto a surface of a fuel feeding pipe 13 heated by generated heat from an engine 10 by a quite simple condensed water feeding means 14 and then fuel heated in a pipe is cooled. The condensed water guiding means 14 is, for example, a component element such as a cylindrical cover of which structure is simple and not cumbersome and which is externally inserted onto the fuel feeding pipe 13, resulting in that an outer size of the device is not increased, and further a manufacturing and fixing cost is quite low. Therefore, it is possible to provide an overheating preventive countermeasure to prevent an increasing cost as much as possible without increasing an external size. |
