FUEL INJECTION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE, METHOD FOR INJECTING FUEL, AS WELL AS AN INTERNAL COMBUSTION ENGINE

摘要

PURPOSE: An internal combustion engine, a fuel injection system, and a fuel injection method for the same are provided to reduce a pressure drop in a high pressure pipe to absolute minimum pressure by applying the volume of a fuel common rail between a fuel injector and the exit of a pressure intensifier. CONSTITUTION: A fuel injection system for an internal combustion engine comprises an injector control unit. The injector control unit controls the injection of fuel(2) into a cylinder(3). The fuel injector is connected to the outlet of a pressure amplifier(6) by a high pressure pipe(5). The pressure intensifier forms an inlet for accommodating fuel which is provided with a low inlet pressure(PL) state. The pressure intensifier changes the low inlet pressure of the fuel into high outlet pressure(PH) for providing to the outlet of the pressure intensifier.
