NOx can be reduced, fear of misfire can be reduced, engine speed can be controlled in the same way regardless of emulsion fuel and oil, and emulsion fuel can be circulated, so that the actual hydrolysis rate can be controlled. It is possible to avoid emulsion fuel without installing a buffer tank, or to consume emulsion fuel in the circulation circuit as much as possible without causing misfire in the case of water system abnormality, and to change the engine speed when changing the actual hydrolysis rate. The aim is to be able to reduce then n n Emulsion with fuel tank 10, injection valve 11, pressurized circulation pump 12, injection pump 42 for controlling the amount of oil, control unit 13, mixer 14, water pump 15 In the fuel supply apparatus, a target yield is set to reduce NOx and misfire, and the amount of water supplied to the mixer is controlled based on the target hydrolysis rate. The control unit performs PID control and changes the control variable based on the command yield so that the engine speed is accelerated and decelerated in the same manner as the operation of oil only. |
