To reduce dead volume to prevent vapor lock by providing plural fuel injection valves adapted to open and close according to the pressure of fule in a fuel pipe to inject fuel from the other end part in a designated timing in the respective designated positions of the fuel pipe.
A fuel injection device 1 comprises a solenoid valve part 2 for supplying fuel, a fuel pipe 3 and plural poppet valves 4 which are fuel injection valves connected to the fuel pipe 3 for injecting fuel. A designated number of poppet valves are arranged in designated positions according to the type and the cylinder number of an engine. The poppet valve 4 has one end part 41 connected to the fuel pipe 3 and the other end part 42 set on the fuel injection side. When pressure in the fuel pipe 3 exceeds a designated alue, the poppet valves 4 inject fuel. Thus, the dead volume can be reduced so as to decrease the generation amount of vapor lock.
