<P>PROBLEM TO BE SOLVED: To provide a technique by which injection fuel supply can be stabilized in a compression ignition internal combustion engine with a plurality of fuel injection valves. <P>SOLUTION: The fuel supply system is equipped with a main fuel injection valve, a sub fuel injection valve, a main fuel accumulator for supplying fuel to the main fuel injection valve, a sub fuel accumulator for supplying the fuel to the sub fuel injection valve, a main fuel supply pipe for making the main fuel accumulator and a fuel pump communicate with each other, and a sub fuel supply pipe for making the sub fuel accumulator and the fuel pump communicate with each other. During a given period of time from a start of fuel injection output from the main fuel injection valve, the fuel is supplied to the sub fuel accumulator. When supplying the fuel to the sub fuel accumulator, e.g., a decompression valve is made to open which is provided in a mid-course of the sub fuel supply pipe coupled to the main fuel supply pipe between the main fuel accumulator and the fuel pump. <P>COPYRIGHT: (C)2007,JPO&INPIT |
