PROBLEM TO BE SOLVED: To reduce the number of components by commonalizing and reducing a shape of a pipe.SOLUTION: A common rail type fuel injection device comprises: a supply pump 11; a common rail 12; plural injectors 14 arranged on each cylinder 2; first fuel injection pipes 15 communicating each injector of a former half with the common rail 12; and second fuel injection pipes 16 communicating each injector of a latter half with the common rail 12. First fuel injection pipe connection ports 20 connected with the first fuel injection pipes 15, and second fuel injection pipe connection ports 21 connected with the second fuel injection pipes 16 are alternately arranged on the common rail 12. The first fuel injection pipe connection ports 20 are arranged at the same pitch P3 as an arrangement pitch P1 of the cylinder 2, and the second fuel injection pipe connection ports 21 are arranged at the same pitch P4 as the arrangement pitch P1 of the cylinder 2, and are eccentric to an intermediate position between the adjacent first fuel injection pipe connection ports 20 on a latter half side of the common rail 12. |
