Abstract
The invention provides a fuel distribution pipe which can restrict an increase of temperature of a fuel flowing within a fuel distribution path of the fuel distribution pipe, whereby it is possible to improve an operation property of the engine. In the fuel distribution pipe, the fuel distribution path is pierced along a line X—X in a direction of a longitudinal axis of the fuel distribution pipe and an injection valve supporting hole for inserting and supporting a rear end portion of the fuel injection valve and a fuel introduction path for supplying a fuel having a pressure increased by a fuel pump are continuously provided in the fuel distribution path of the fuel distribution pipe, and a cooling water flow path extending along the line X—X in the direction of the longitudinal axis of the fuel distribution path and sectioned from the fuel distribution path is provided on an outer periphery of the fuel distribution path, thereby introducing a cooling water into the cooling water flow path.
