PURPOSE:To improve combustion efficiency and remarkably reduce suspended particulate matters in exhaust gas by utilizing a plurality of kinds of fuel in the same system, injecting high-temperature and high-pressure liquefied fuel from an injection nozzle and at the same time gasifying it. CONSTITUTION:A heater 22 of a fuel tank 15 is required when B heavy oil or C heavy oil is used. Fuel and water is supplied under pressurizing to a high- temperature and pressurizing mixer 28 through the fuel tank 15, a water tank 16, a check valve 17, a heating area 18 generated by an engine heat and the heater, by means of a fuel pump 19 and a water pump 20. Pressure at this time is set by setting a sequence valve 3. The set values of the sequence valve 3 is of course the same for water supplying and fuel supplying. Emulsion fuel in the mixer 28 passes a circulation passage 27, and is further increased in its temperature by means of a heat exchanger 18 having the heater 22. It is thereby possible to realize a low fuel consumption of an engine and reduce suspended particulate matters and sulfur oxides, etc., included in exhaust gas, and to attain energy saving and low-pollution at the same time. |
