An injection device for a fuel motor is provided to enable boot rate shaping and inject a small amount of fuel under a lower pressure in a combustion chamber of the fuel motor. An injection device for a fuel motor includes a fuel reservoir(1), a high pressure fuel conveyance device(2), a pressure tank(3), a 3/2 way valve(4), and an injector(7). The fuel reservoir stores fuel. The high pressure fuel conveyance device conveys fuel with a pressure of 600 to 2500 bar. The pressure tank receives the fuel conveyed by the high pressure fuel conveyance device. The 3/2 way valve is connected to the pressure tank. The 3/2 way valve supplies the fuel to the injector depending on its adjustment position. In a first position(4.1) of the 3/2 way valve, a connection pipe(10.2) having a pressure regulation valve and a adjustable neck is separated from the 3/2 way valve.
