<p>The present invention relates to a fuel filter for diesel vehicles and, more specifically, to a device for preventing moisture or paraffin included in diesel fuel from stopping fuel supply by being frozen in the winter, by improving the fuel filter for diesel vehicles. The filter comprises a body part (100) filtering fuel by embedding a filter member in a housing (110); and a head part (200) which is prepared at the inlet of the body part (100) and comprises a supply line (210) having an inlet connected to a fuel tank (10) and having an outlet connected to a common rail (30) of a diesel engine (20) via the body part (100), a collecting line (220) having an inlet connected to the common rail (30) of the diesel engine (20) and having an outlet connected to the fuel tank (10), a circulation line (230) connected from the collecting line (220) to the body part (100), and a valve (240) prepared in the circulation line (230) to open and close the circulation line (230) according to the temperature of fuel in the body part (100). Thus, as the fuel filter is heated by using high temperature fuel returning from the common rail of the diesel engine according to the temperature of fuel in the fuel filter, fuel is more smoothly supplied to diesel vehicles while driving.</p> |
