Highly pressurized common rail for internal combustion engine

摘要

A partitioning wall (111) divides the inner space of the piping main body into fuel flow passages (101,102) that communicate through communication portions (105-105d). A fuel introduction portion leads to the fuel flow passage (101). Fuel injection devices are inserted into inserting sections (104a-104d) that are formed to communicate with at least one of the fuel flow passages. An independent claim is also included for a method applicable to a highly pressurized fuel piping for an internal combustion engine.
