The unevenness of injection rates of cylinders is reduced in a fuel supply system of a direct injection engine which uses a variable-displacement single plunger pump. The unevenness of injection rates of cylinders can be reduced by effecting a control such that the cam 100, which drives the high-pressure fuel pump 101, makes one reciprocation, while the engine makes explosions in two cylinders, and by causing the controller 55 to extend the injection time width of one of two injectors 54 which inject during one discharge of the high-pressure fuel pump and to shorten the injection time width of the other injector.
