PROBLEM TO BE SOLVED: To provide an emulsion fuel supply device of a diesel engine showing a high responsiveness to change in a water ratio by reducing an emulsifing fuel amount. SOLUTION: This device is a loop passing a mixer 45 provided before the fuel flow in part to the fuel injection part 3 in a fuel circulation loop, an emulsion fuel return line 46 for communicating a fuel return line 26 with the position near suction side of the mixer 45 and a fuel injection part 3 and is provided with an emulsion fuel circulation loop formed smaller than the inner volume of the fuel circulation loop and a controller for switching the fuel circulation loop to the emulsion fuel circulation loop. By the switching of the controller, an operatable pure fuel circulation loop is formed separatingly from the emulsion fuel circulation loop. Thereby, the amount of an emulsified fuel is reduced in comparison with the past and change in the water ratio of the fuel can be carried out in a short time and the responsiveness becomes high. |
