PURPOSE:To provide an emulsion fuel engine which enables the reduction in exhaust of NC and white smoke when the engine load is low or the engine is started at a low temperature. CONSTITUTION:A first fuel tank stores a first fuel, and second fuel tank stores a second fuel, a three-way valve 42 mixes the first fuel from the first fuel tank and the second fuel from the second fuel tank at a specified ratio and thus second the mixture and a circulation path 31 circulates and retains emulsion fuel as mixture of the first and second fuel sent from the three-way valve 42, by using a circulation pump 41. The circulation path 31 is then connected to an injection pipe 17 pathway, respectively, via a connection pipe 33a-33d, for each cylinder. A magnet spill valve 34a-34d is provided to a branch pipe branching from the point of the injection pipe, a certain distance away from the connection point toward an injection pump. A controller 51 is provided which opens magnet spill valves corresponding to cylinders suspended at least at the time of low engine load or cold engine state. |
