FUEL INJECTION SYSTEM FOR INTERNAL COMBUSTION ENGINE

摘要

A fuel injection system that can efficiently supply high-pressure fuel to a fuel injection section of an internal combustion engine, that can be easily designed and produced by simplifying its mechanical structure, and that has excellent maintainability for repair and removal and installation. The fuel injection system has a cassette pump that is removably attached to an internal combustion engine having a cam and in which a plunger reciprocating with the rotation of the cam raises the pressure of fuel to a high level and sends the fuel under pressure, a common rail that accumulates the high-pressure fuel sent under pressure from the cassette pump and supplies the high-pressure fuel to fuel injection sections, a pressure regulation section that regulates the pressure in the common rail, and pressure control means that controls the pressure regulation section according to the value of the pressure in the common rail.
