Fuel supply system i.e. common rail fuel supply system, for internal combustion engine i.e. marine diesel internal combustion engine, has casing with wall thickness withstanding emergency operating pressure in case of fuel line breakage

摘要

The system has a pump device for pumping a fuel from a low pressure region of the system to a high pressure region. A pressure storage system (13) is connected with injectors by a high pressure fuel line (10). The high pressure fuel line connects the pump device with the pressure storage system, where the high pressure fuel line stays permanently under high pressure. A casing (15) is attached to the high pressure fuel line. The casing exhibits a wall thickness that withstands a definite emergency operating pressure in case of a breakage of the high pressure fuel line.
