FUEL INJECTION SYSTEM FOR INTERNAL COMBUSTION ENGINE

Title:

FUEL INJECTION SYSTEM FOR INTERNAL COMBUSTION ENGINE

Document Type and Number:

WIPO Patent Application WO/2007/097052

Kind Code:

A1

Abstract:

A fuel injection system for an internal combustion engine, which can efficiently feed high-pressure fuel to fuel injection sections of the internal combustion engine, where different kinds of pumps can be used, and which has excellent maintainability including service, replacement, and attachment and detachment of the pump. The fuel injection system has a cassette pump and a common rail. The cassette pump is detachably attached to the internal combustion engine having a cam and pressurizes and feeds the fuel under pressure as the cam rotates. The common rail accumulates the high-pressure fuel fed under pressure from the cassette pump and feeds the high-pressure fuel to the fuel injection sections. The fuel injection system is characterized in that the cam is secured to a camshaft, the camshaft is connected to the crankshaft of the internal combustion engine at a predetermined gear ratio, and the cassette pump has only a single plunger for pressurizing the fuel by the rotation of the cam and a single discharge valve for discharging the fuel pressurized by the plunger.
