HIGH-PRESSURE FUEL LINE OF INTERNAL COMBUSTION ENGINE, PROMOTING SIMPLIFICATION OF MANUFACTURING PROCESS AND REDUCTION OF MANUFACTURING COST

摘要

PURPOSE: A high-pressure fuel line of an internal combustion engine is provided to reduce a deviation of fuel injection amount under high fuel pressure and to facilitate manufacture at low cost. CONSTITUTION: A high-pressure fuel line of an internal combustion engine includes a fuel tank and plural fuel injection devices to which fuel supplied from the fuel tank is distributed. The high-pressure fuel line of the internal combustion engine comprises a pipe body having an outer peripheral wall and a partition plate formed integrally with the outer peripheral wall; first and second fuel passages(101,102) partitioned by the partition plate of the pipe body and formed in the inner space of the pipe body and extended parallel; a fuel inlet part(103) communicating with the first fuel passage; plural insertion parts(104a¯104d) communicating with at least one of the first and second fuel passages; and plural communicating parts(105a¯105d) making the first and second fuel passages communicate with each other. The fuel injection devices are each inserted in the insertion parts.
