Abstract
A supply pump for a common rail fuel injection system applicable to a multi-cylinder engine, that exerts a smaller load on a drive power transmission mechanism connecting the engine to the supply pump. To this end, fuel delivery timing of the supply pump is optimized. The number of engine cylinders may be different from that of fuel delivery of the supply pump. A first fuel delivery end timing is 30.degree..+-.5.degree. after compression top dead center of #1 cylinder, and subsequent fuel delivery end timings come at constant intervals. The constant intervals are obtained by dividing 720.degree. by the number of fuel delivery per two rotations of an engine crankshaft.
