A fuel injection system includes (i) an injector for injecting gaseous fuel and liquid fuel into a cylinder of an internal combustion engine, (ii) a gaseous fuel supplying unit having a gaseous feel tank as a first high-pressure accumulating source for pressurizing gaseous fuel, (iii) a liquid fuel supplying unit having a common rail as a second high-pressure accumulating source for pressurizing liquid fuel; (iv) a fuel pump as a pressure feeding unit that pressure feeds liquid fuel to the common rail; and (v) a compressor as a pressure increasing unit, which is operated under pressure of the pressurized gaseous fuel to increase pressure of liquid fuel pressure fed from the fuel pump.
